    Full Text Available Objectives: This study aimed to assess risky driving behaviours among medical students in Erbil, Iraq, and to explore the relationship between risky driving behaviours and perceptions of risky driving. Methods: This self-administered questionnaire-based survey was conducted from January to May 2014 among a random sample of 400 medical students at Hawler Medical University in Erbil. The questionnaire was designed to assess the frequency of engagement in 21 risky driving behaviours, the perceived risk of each behaviour and the preference for each behaviour as ranked on a 5-point scale. Results: A total of 386 students responded to the survey (response rate: 96.5%. Of these, 211 reported that they currently drove a vehicle (54.7%. Drivers most frequently engaged in the following behaviours: playing loud music (35.9%, speeding (30.4%, allowing front seat passengers to not wear seat belts (27.9% and using mobile phones (27.7%. Least frequent driving behaviours included not stopping at a red light (3.9%, driving while sleepy (4.4%, driving after a mild to moderate intake of alcohol (4.5% and drunk driving (6.4%. Mean risky driving behaviour scores were significantly higher among males (P 20-year-olds (P = 0.028. There was a significant positive relationship between the preference for risky behaviours and risky driving behaviours (beta = 0.44; P <0.001. Conclusion: Medical students in Erbil reported high frequencies of several serious risky driving behaviours. The preference for risky behaviours was found to be an important predictor of risky driving behaviours among medical students in Erbil.

    Adolescents are at a greater risk of being involved in traffic accidents than most other age groups, even before they start driving cars. This article aims to determine the factor structure of a self-report questionnaire measuring adolescent risky cycling behaviour, the ACBQ (Adolescent Cycling Behaviour Questionnaire). The questionnaire's structure was based on the widely used Driver Behaviour Questionnaire (DBQ). A sample of secondary school students (N = 1749; age range: 13-18 years) filled out the questionnaire. Factor analysis revealed a three-factor structure underlying the questionnaire, which was confirmed on two equally large portions of the entire sample. These three underlying factors were identified as errors, common violations and exceptional violations. The ACBQ is a useful instrument for measuring adolescents' risky cycling behaviour.

    Self-report measures of driving-related attitudes and beliefs miss potentially important precursors of driving behaviour, namely, automatic and implicit thought processes. The present study used an adapted Go/No-go Association Task to measure implicit thought without relying on the participants......' self-reports. Implicit attitudes towards safe and risky driving were measured in 53 Danish drivers (31 female, 22 male). Further, we explored the relationship between implicit attitudes towards risky and safe driving, and self-reported driving behaviour and skills. The results suggest that implicit...... attitudes were significantly related to self-reported driving behaviour and skills for male (but not female) drivers. Pending future research with larger sample sizes, the difference between implicit attitudes towards safe versus risky driving that we observed may contribute to a greater theoretical...

    While there is research indicating that many factors influence the young novice driver's increased risk of road crash injury during the earliest stages of their independent driving, there is a need to further understand the relationship between the perceived risky driving behaviour of parents and friends and the risky behaviour of drivers with a Provisional (intermediate) licence. As part of a larger research project, 378 drivers aged 17-25 years (M=18.22, SD=1.59, 113 males) with a Provisional licence completed an online survey exploring the perceived riskiness of their parents' and friends' driving, and the extent to which they pattern (i.e. base) their driving behaviour on the driving of their parents and friends. Young drivers who reported patterning their driving on their friends, and who reported they perceived their friends to be risky drivers, reported more risky driving. The risky driving behaviour of young male drivers was associated with the perceived riskiness of their fathers' driving, whilst for female drivers the perceived riskiness of their mothers' driving approached significance. The development and application of countermeasures targeting the risky behaviour of same-sex parents appears warranted by the robust research findings. In addition, countermeasures need to encourage young people in general to be non-risky drivers; targeting the negative influence of risky peer groups specifically. Social norms interventions may minimise the influence of potentially-overestimated riskiness. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Several studies have shown that risky driving is especially prevalent among young drivers and recent research has pointed out that driving in adolescence should be investigated in the more general context of adolescent development. The first aim of this contribution was to analyze involvement in risky driving in a normative sample of 645 Italian adolescents, boys and girls, aged 14-17, through a self-report questionnaire. A second aim was to evaluate the association between risky driving and lifestyle, defined as involvement in other health risk behaviors and leisure activities. The main results showed that many adolescents drove cars and motorcycles without the required driving license and the most frequent offences were speeding and failure to maintain a safe braking distance. Gender and age differences were also investigated. Results concerning the association between risky driving and lifestyle showed that risky driving was not an isolated behavior. Boys who displayed risky driving practices were more likely to adopt a lifestyle characterized by high involvement in antisocial behaviors, tobacco smoking, comfort eating and time spent in non-organized activities with friends. Girls involved in risky driving were more likely to be involved in other risk-taking behaviors, antisocial behaviors and drug use.

    Risky driving is a common cause of traffic accidents and injuries. However, there is no clear evidence of how difficulties in emotion regulation contribute to risky driving behavior, particularly in small post-Soviet countries. The present study aimed to investigate the relationship between difficulties in emotion regulation and self-reported risky driving behavior in a sample of Lithuanian drivers. A total of 246 nonprofessional Lithuanian drivers participated in a cross-sectional survey. Difficulties in emotion regulation were assessed using the Difficulties in Emotion Regulation Scale (DERS; Gratz and Roemer 2004), and risky driving behavior was assessed using the Manchester Driver Behaviour Questionnaire (DBQ; Lajunen et al. 2004). Males scored higher than females in aggressive violations and ordinary violations. Females scored higher for the nonacceptance of emotional responses, whereas males had more difficulties with emotional awareness than females. More difficulties in emotion regulation were positively correlated with driving errors, lapses, aggressive violations, and ordinary violations for both males and females. Structural equation modeling showed that difficulties in emotion regulation explained aggressive and ordinary violations more clearly than lapses and errors. When controlling for interactions among the distinct regulation difficulties, difficulties with impulse control and difficulties engaging in goal-directed behavior predicted risky driving. Furthermore, nonacceptance of emotional responses and limited access to emotion regulation strategies were related to less violations and more driving errors. Emotion regulation difficulties were associated with the self-reported risky driving behaviors of Lithuanian drivers. This provides useful hints for improving driver training programs in order to prevent traffic injuries.

    Risky driving is a significant contributor to road traffic crashes, especially in young drivers. Transient mind wandering states, an internal form of distraction, are associated with faster driving, reduced headway distance, slower response times, reduced driver vigilance, and increased crash risk. It is unclear whether a trait tendency to mind wander predicts risky driving, however. Mind wandering is also associated with poor executive control, but whether this capacity moderates the putative link between mind wandering tendency and risky driving is uncertain. The present study tested whether mind wandering tendency predicts risky driving behaviour in young male drivers aged 18-21 (N=30) and whether this relationship is mediated by driver vigilance and moderated by executive control capacity. Mind wandering was measured with the Sustained Attention to Response Task (SART) and the Daydreaming Frequency Scale (DDFS). Risky driving was assessed by mean speed in a driving simulator and driver vigilance was quantified by horizontal eye movements measured with eye tracking. Results showed that greater mind wandering tendency based on SART performance significantly predicts faster mean speed, confirming the main hypothesis. Neither driver vigilance mediated nor executive control capacity moderated this relationship as hypothesized. These findings speak to the complexity of individual differences in mind wandering. Overall, mind wandering tendency is a significant marker of risky driving in young drivers, which could guide the development of targeted interventions. Copyright © 2017 Elsevier Ltd.

    Iran has one of the highest fatality rates due to road traffic crashes (RTC) in the world. The disability adjusted life years (DALYs) for RTC in Iran is more than 1,300,000 years, which is more than that for any other disease such as cardiovascular or cancer. We evaluated risky driving behaviors in Tehran, the capital of Iran. A retrospective analysis was conducted based on the data obtained from the Tehran Police Safety Driving Department. Offenses and crashes were studied in different municipal districts in Tehran from March 2006 to March 2007. The inclusion criteria were risky driving behaviors fined by the police. Nonbehavioral offences were excluded. There were 3,821,798 offenses in Tehran. Not wearing a seat belt was the most common (59%) example of risky driving behavior, followed by tailgating, not wearing motorcycle helmets, talking on the cell phone while driving, overtaking from the wrong side, speeding, not driving between the lanes, weaving in and out of traffic, left deviation, and changing lanes without signals. The most common causes of RTC in Tehran are speeding, overtaking from the wrong side, and the rapid changing of driving lanes. The study factors effective in preventing risky driving behaviors in Tehran is recommended. The consideration of specific characteristics of the municipal districts is necessary to reduce risky driving behaviors.

    ; further, self-reports of the intention to drive safely (or not) are socially sensitive. Therefore, we examined automatic preferences towards safe and risky driving with a Go/No-go Association Task (GNAT). The results suggest that (1) implicit attitudes towards driving behavior can be measured reliably...... with the GNAT; (2) implicit attitudes towards safe driving versus towards risky driving may be separable constructs. We propose that research on driving behavior may benefit from routinely including measures of implicit cognition. A practical advantage is a lesser susceptibility to social desirability biases......, compared to self-report methods. Pending replication in future research, the apparent dissociation between implicit attitudes towards safe versus risky driving that we observed may contribute to a greater theoretical understanding of the causes of unsafe and risky driving behavior....

    The study aims to evaluate how the factors of motivation and attitudes about traffic safety are related to risky driving evaluated by young drivers both subjectively and objectively. Risky driving was evaluated in three ways: self-knowledge, driving in a simulation environment, and recalled violations of road traffic regulations as well as accidents caused. 226 respondents aged 18–29 answered the questions from the self-knowledge questionnaire, 40 of them participated in the experiment of dri...

    Drivers' risk-taking is a key issue of road safety. This study explored individual differences in drivers' decision-making, linking external behaviours to internal neural activity, to reveal the cognitive mechanisms of risky driving. Twenty-four male drivers were split into two groups (risky vs. safe drivers) via the Drivier Behaviour Questionnaire-violation. The risky drivers demonstrated higher preference for the risky choices in the paradigms of Iowa Gambling Task and Balloon Analogue Risk Task. More importantly, the risky drivers showed lower amplitudes of feedback-related negativity (FRN) and loss-minus-gain FRN in both paradigms, which indicated their neural processing of error-detection. A significant difference of P300 amplitudes was also reported between groups, which indicated their neural processing of reward-evaluation and were modified by specific paradigm and feedback. These results suggested that the neural basis of risky driving was the decision patterns less revised by losses and more motivated by rewards. Risk-taking on the road is largely determined by inherent cognitive mechanisms, which can be indicated by the behavioural and neural patterns of decision-making. In this regard, it is feasible to quantize drivers’ riskiness in the cognitive stage before actual risky driving or accidents, and intervene accordingly.

    Road traffic accidents (RTAs) constitute a serious global health risk, and evidence suggests that young drivers are significantly overrepresented among those injured or killed in RTAs. This study explores the role of anger, impulsivity, sensation seeking and driver attitudes as correlates for risky driving practices among drivers, drawing comparisons between age and gender. The study used a cross-sectional survey design, with a sample of 306 post-graduate university students from two universities in Durban, South Africa, who completed the self-administered questionnaire. The results indicate that drivers with higher driver anger, sensation seeking, urgency, and with a lack of premeditation and perseverance in daily activities were statistically more likely to report riskier driving acts. Males reported significantly more acts of risky driving behaviour (RDB) than females. Driver attitudes significantly predicted self-reported acts of RDB on most indicators. Older drivers (25 years and older) had safer driver attitudes and a lower sense of sensation seeking and urgency in life. Interventions targeting young drivers, which focus on impeding the manifestation of anger, impulsivity and sensation seeking are recommended. Also, the empirical support for the attitude-behaviour hypothesis evidenced in this study vindicates the development or continuation of interventions that focus on this dynamic.

    This paper presents the results of a national survey of drivers in the Republic of Ireland that sought to examine psychological predictors of specific driving behaviours. 1638 respondents attending National Car Testing (NCT) centres nationwide completed a questionnaire battery that included personality, attitudinal, locus of control and social influence measures. The driving behaviours examined were drawn from a Driving Behaviour Scale (Iversen, 2004) and included Speeding and Rule Violation, Reckless Driving, Wearing of Seat Belts, Cautious Driving and Drink Driving. Cross-group comparisons suggested that males engaged in more risky and less cautious driving behaviours than females, and participants under the age of 25 were more risky and less cautious than those 25 years or older. Statistically significant models of each driving outcome emerged. The best model fit was for speeding and rule violation, which was predicted by a model including positive attitudes towards speeding, greater normative influences of friends and higher perceived behavioural control, extraversion and driving anger. These findings offer important insights into the correlates of different driving behaviours and can help inform the work of road safety practitioners. Copyright © 2012 Elsevier Ltd.

    The risky driving of young drivers may owe in part to youthful motivations (such as experience-seeking, authority rebellion, desire for peer approval) combined with incompletely developed impulse control. Although self-reported impulsiveness has been positively associated with self-reports of risky driving, results based on objective measures of response inhibition (e.g., Go/No-go tasks) have been inconclusive. The present study examined interrelationships between measures of response inhibition, self-report impulsiveness scales, and responses to events during a simulated drive that were designed to detect impulsive, unsafe behaviours (e.g., turning across on-coming traffic). Participants were 72 first-year Psychology students. More speeding and "Unsafe" responding to critical events during simulated driving were associated with poorer impulse control as assessed by commission errors during a Go/No-Go task. These results consolidate evidence for a relationship between impulse control and risky driving amongst young drivers. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The present study examined the predictive effects of five impulsivity-like traits (Premeditation, Perseverance, Sensation Seeking, Negative Urgency, and Positive Urgency) on driving outcomes (driving errors, driving lapses, driving violations, cell phone driving, traffic citations, and traffic collisions). With a convenience sample of 266 college student drivers, we found that each of the impulsivity-like traits was related to multiple risky driving outcomes. Positive Urgency (tendency to act impulsively when experiencing negative affect) was the most robust predictor of risky driving outcomes. Positive Urgency is a relatively newly conceptualized impulsivity-like trait that was not examined in the driving literature previously, suggesting a strong need to further examine its role as a personality trait related to risky driving. These findings generally support the multidimensional assessment of impulsivity-like traits, and they specifically support the addition of Positive Urgency to a list of risk factors for risky driving behaviors.

    The purpose of this investigation was to determine the relationship between distress tolerance and risky and aggressive driving. Distress tolerance, defined as an individual's capability to experience and endure negative emotional states, was hypothesized to be related negatively to aggressive driving and risky driving. An anonymous, web-based survey of 769 college students was conducted at a large East Coast university. After controlling for age, gender, race, ethnicity, year in school, grade point average, and driving frequency, distress tolerance was significantly inversely related to reported risky driving and aggressive driving. College drivers who have a diminished capacity to endure frustration without experiencing negative emotional states (i.e., low distress tolerance) tend to drive aggressively and in a risky manner. Traditional deterrence-based approaches to highway safety may benefit from inclusion of a wider array of prevention strategies that focus on emotion regulation while driving.

    The overrepresentation of young drivers in poor road safety outcomes has long been recognized as a global road safety issue. In addition, the overrepresentation of males in crash statistics has been recognized as a pervasive young driver problem. Though progress in road safety evidenced as a stabilization and/or reduction in poor road safety outcomes has been made in developed nations, less-developed nations contribute the greatest road safety trauma, and developing nations such as Colombia continue to experience increasing trends in fatality rates. The aim of the research was to explore sex differences in self-reported risky driving behaviors of young drivers, including the associations with crash involvement, in a sample of young drivers attending university in Colombia. The Spanish version of the Behaviour of Young Novice Drivers Scale (BYNDS-Sp) was applied in an online survey to a sample of 392 students (225 males) aged 16-24 years attending a major university. Appropriate comparative statistics and logistic regression modeling were used when analyzing the data. Males reported consistently more risky driving behaviors, with approximately one quarter of all participants reporting risky driving exposure. Males reported greater crash involvement, with violations such as speeding associated with crash involvement for both males and females. Young drivers in Colombia appear to engage in the same risky driving behaviors as young drivers in developed nations. In addition, young male drivers in Colombia reported greater engagement in risky driving behaviors than young female drivers, a finding consistent with the behaviors of young male drivers in developed nations. As such, the research findings suggest that general interventions such as education, engineering, and enforcement should target transient rule violations such as speeding and using a handheld mobile phone while driving for young drivers in Colombia. Future research should investigate how these

  20. Personality, Executive Control, and Neurobiological Characteristics Associated with Different Forms of Risky Driving.

    Full Text Available Road crashes represent a huge burden on global health. Some drivers are prone to repeated episodes of risky driving (RD and are over-represented in crashes and related morbidity. However, their characteristics are heterogeneous, hampering development of targeted intervention strategies. This study hypothesized that distinct personality, cognitive, and neurobiological processes are associated with the type of RD behaviours these drivers predominantly engage in.Four age-matched groups of adult (19-39 years males were recruited: 1 driving while impaired recidivists (DWI, n = 36; 2 non-alcohol reckless drivers (SPEED, n = 28; 3 drivers with a mixed RD profile (MIXED, n = 27; and 4 low-risk control drivers (CTL, n = 47. Their sociodemographic, criminal history, driving behaviour (by questionnaire and simulation performance, personality (Big Five traits, impulsivity, reward sensitivity, cognitive (disinhibition, decision making, behavioural risk taking, and neurobiological (cortisol stress response characteristics were gathered and contrasted.Compared to controls, group SPEED showed greater sensation seeking, disinhibition, disadvantageous decision making, and risk taking. Group MIXED exhibited more substance misuse, and antisocial, sensation seeking and reward sensitive personality features. Group DWI showed greater disinhibition and more severe alcohol misuse, and compared to the other RD groups, the lowest level of risk taking when sober. All RD groups exhibited less cortisol increase in response to stress compared to controls.Each RD group exhibited a distinct personality and cognitive profile, which was consistent with stimulation seeking in group SPEED, fearlessness in group MIXED, and poor behavioural regulation associated with alcohol in group DWI. As these group differences were uniformly accompanied by blunted cortisol stress responses, they may reflect the disparate behavioural consequences of dysregulation of the stress system. In sum, RD

    Although there are several studies on the effects of personality and attitudes on risky driving among young drivers, related research in older drivers is scarce. The present study assessed a model of personality-attitudes-risky driving in a large sample of active older drivers. A cross-sectional design was used, and structured and anonymous questionnaires were completed by 485 older Italian drivers (Mean age=68.1, SD=6.2, 61.2% males). The measures included personality traits, attitudes toward traffic safety, risky driving (errors, lapses, and traffic violations), and self-reported crash involvement and number of issued traffic tickets in the last 12 months. Structural equation modeling showed that personality traits predicted both directly and indirectly traffic violations, errors, and lapses. More positive attitudes toward traffic safety negatively predicted risky driving. In turn, risky driving was positively related to self-reported crash involvement and higher number of issued traffic tickets. Our findings suggest that theoretical models developed to account for risky driving of younger drivers may also apply in the older drivers, and accordingly be used to inform safe driving interventions for this age group.

    We examined the prevalence of impaired driving among US high school students and associations with substance use and risky driving behavior. We assessed driving while alcohol or drug impaired (DWI) and riding with alcohol- or drug-impaired drivers (RWI) in a nationally representative sample of 11th-grade US high school students (n = 2431). We examined associations with drinking and binge drinking, illicit drug use, risky driving, and demographic factors using multivariate sequential logistic regression analysis. Thirteen percent of 11th-grade students reported DWI at least 1 of the past 30 days, and 24% reported RWI at least once in the past year. Risky driving was positively associated with DWI (odds ratio [OR] = 1.25; P phone calls (OR = 3.2) while driving. Our findings suggest the need for comprehensive approaches to the prevention of DWI, RWI, and other risky driving behavior.

  3. Reducing Risky Security Behaviours: Utilising Affective Feedback to Educate Users

    Full Text Available Despite the number of tools created to help end-users reduce risky security behaviours, users are still falling victim to online attacks. This paper proposes a browser extension utilising affective feedback to provide warnings on detection of risky behaviour. The paper provides an overview of behaviour considered to be risky, explaining potential threats users may face online. Existing tools developed to reduce risky security behaviours in end-users have been compared, discussing the success rates of various methodologies. Ongoing research is described which attempts to educate users regarding the risks and consequences of poor security behaviour by providing the appropriate feedback on the automatic recognition of risky behaviour. The paper concludes that a solution utilising a browser extension is a suitable method of monitoring potentially risky security behaviour. Ultimately, future work seeks to implement an affective feedback mechanism within the browser extension with the aim of improving security awareness.

    The purpose of this study was to explore the role of personality traits and driving experience in the prediction of risky driving behaviors and accident risk among Chinese population. A convenience sample of drivers (n=511; mean (SD) age=34.2 (8.8) years) completed a self-report questionnaire that was designed based on validated scales for measuring personality traits, risky driving behaviors and self-reported accident risk. Results from structural equation modeling analysis demonstrated that the data fit well with our theoretical model. While showing no direct effects on accident risk, personality traits had direct effects on risky driving behaviors, and yielded indirect effects on accident risk mediated by risky driving behaviors. Both driving experience and risky driving behaviors directly predicted accident risk and accounted for 15% of its variance. There was little gender difference in personality traits, risky driving behaviors and accident risk. The findings emphasized the importance of personality traits and driving experience in the understanding of risky driving behaviors and accident risk among Chinese drivers and provided new insight into the design of evidence-based driving education and accident prevention interventions.

    We explored the risky driving behaviors and risk perceptions of a cohort of young novice drivers and sought to determine their associations with crash risk. Provisional drivers aged 17 to 24 (n = 20 822) completed a detailed questionnaire that included measures of risk perception and behaviors; 2 years following recruitment, survey data were linked to licensing and police-reported crash data. Poisson regression models that adjusted for multiple confounders were created to explore crash risk. High scores on questionnaire items for risky driving were associated with a 50% increased crash risk (adjusted relative risk = 1.51; 95% confidence interval = 1.25, 1.81). High scores for risk perception (poorer perceptions of safety) were also associated with increased crash risk in univariate and multivariate models; however, significance was not sustained after adjustment for risky driving. The overrepresentation of youths in crashes involving casualties is a significant public health issue. Risky driving behavior is strongly linked to crash risk among young drivers and overrides the importance of risk perceptions. Systemwide intervention, including licensing reform, is warranted.

    Motor vehicle accidents are the leading cause of injury-related fatalities in China and pose the most serious threat to driving safety. Driver personality is considered as an effective predictor for risky driving behavior and accident liability. Previous studies have focused on the relationship between personality and risky driving behavior, but only a few of them have explored the effects of personality variables on accident involvement. In addition, few studies have examined the effects of personality on Chinese drivers' risky driving and accident involvement. The present study aimed to examine the effects of personality variables on Chinese drivers' unsafe driving behaviors and accident involvement. Two hundred and twenty-four Chinese drivers aged 20 to 50 were required to complete questionnaires assessing their personality traits (anger, sensation-seeking, altruism, and normlessness), risky driving behaviors (aggressive violations, ordinary violations), and accident involvement (all accidents, serious accidents, at-fault accidents). Multivariate regression analyses, adjusting for gender, age, and overall mileage, were conducted to identify the personality traits related to risky driving behaviors and accident involvement. Participants' personality traits were found to be significantly correlated with both risky driving behavior and accident involvement. Specifically, the traits of anger and normlessness were effective predictors for aggressive violations. The traits of anger, sensation-seeking, normlessness, and altruism were effective predictors for ordinary violations. Moreover, altruism and normlessness were significant predictors for the total number of accidents participants had during the past 3 years. Consistent with previous studies, the present study revealed that personality traits play an important role in predicting Chinese drivers' risky driving behaviors. In addition, Chinese drivers' personality characteristics were also associated with accident

    Worldwide statistics indicate that novice drivers are still one of the riskiest drivers’ groups as they highly contribute to road accidents and traffic rules violations. Thus, the psychological variables that allow predicting whether novice drivers will violate traffic rules are important in risky driving research. The aim of this study is to find out if pre-drivers’ attitudes towards risky driving measured before obtaining driving license could predict future traffic offences during the firs...

    Full Text Available BACKGROUND: The use of psychoactive substances is one of the most important public health issues. Tobacco, alcohol and illicit drugs are among the top risk factors for ill-health defined by World Health Organisation. The risky behaviours acquired in teenage can be magnified or decreased during university when a person starts having more awareness about the importance of own wellness. This paper describes the results of the project "Sportello Salute Giovani" ("Youth Health Information Desk" with respect to risky behaviours in a large sample of Italian university students. MATERIALS AND METHODS: 18 questions of the survey "Sportello Salute Giovani" dealing with risky behaviors, the use of psychoactive substances such as tobacco, alcohol and illicit drugs were included. Absolute and relative frequencies were calculated. Besides, chi square test were used to test the differences in sex, age class and socio-economic status. RESULTS: About 24% of the interviewed students currently smokes. 89% and 42.2% respectively drinks at least rarely or weekly beer, wine or spirits. About 40% of students smoked at least a joint and about 2% used other drugs (mostly cocaine. CONCLUSION: The "Sportello Salute Giovani" survey suggests that the frequency of risky behaviours in Italian university students is not reassuring, although they should be aware about the negative consequences on their and others health because of their educational level.

    A range of situational and lifestyle-related factors in drink-driving fatal accidents were studied involving young adult and middle-aged male drivers in Finland. Fatal drink-driving accidents were compared to fatal accidents in which the driver had been sober. The study included all 18-to 59-year-old male drivers' fatal car and van accidents investigated by the Road Accident Investigation Teams in Finland between 2000 and 2002 (n = 366 accidents). The variables describing the situation included the time of the accident, the road condition, the speed, possession of a valid licence, seat-belt usage, and the presence of passengers. The study found that among young adult males most of the studied situational factors bore no relation to the state of the driver (sober or drink driver). Only the time of day, seat-belt, usage, and possession of a valid licence were related to the state of the driver. Among middle-aged male drivers, drink-driving and sober driving accidents differed more clearly. Further, when the social situation in the car was examined, it was found that accidents of sober and drink drivers differed from each other within the group of middle-aged drivers but not within the group of young adult drivers. Heavy alcohol usage was found to characterize the lifestyle of the studied middle-aged drink drivers. It was concluded that for young adult males drink-driving was a part of a more general risky driving style. Among middle-aged males drink-driving was more related to a risky lifestyle with drinking problems. Possible countermeasures are discussed with regard to drink-driving among young adult and middle-aged males.

    2013-03-01

    Being a hurried driver is associated with a variety of risky driving behaviors, yet the mechanisms underlying this behavior remain unknown. Distress tolerance, defined as an individual's capability to experience and endure negative emotional states, was examined as a predictor of hurried driving among 769 college students. Results indicate that after controlling for age, gender, race, ethnicity, the student's year in school, their grade point average, driving frequency, angry driving, aggressive driving as well as other forms of self-reported risky driving; hurried driving was significantly associated with lower levels of distress tolerance. Hurried drivers also reported greater levels of frustration and impatience with other drivers, suggesting that they have difficulty in withstanding or coping with negative psychological states when driving. Traditional traffic safety campaigns that emphasize enforcement may be less successful with these drivers. The need to develop campaigns that address the affective coping abilities that contribute to this behavioral pattern is discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Due to its perception as a disease of development, road traffic accident and related injuries tend to be under recognized as a major health problem in developing countries. However, majority of the world's fatalities on the roads occur in low income and middle income countries. Since the main cause of road traffic accident is attributed to human risky behaviors, it is important to identify significant factors for risky behaviors of drivers. Methods A quantitative cross-sectional study with a sample size of 350 drivers was conducted in April 2011. The study was conducted among Taxi, Bajaj (three tire vehicles and private owned car drivers. After proportion to size allocation for Taxi (75, Baja (103 and private owned car (172 drivers, we used systematic random sampling method to identify illegible study subjects. Data was collected with face to face interview using a pretested questioner. Univariate, bivariate and multivariate analysis was done using SPSS version 16. Results The mean age of the respondents was 28.7 (SD 9.9. Majority were 339 (96.9% males. Significant number of the study subjects 233 (66.6% had risky driving behaviors. More than a quarter 100 (28.6% had less knowledge about basic traffic signs. Majority of drivers 181 (51.7% had negative attitude towards risky driving behaviors. Significant percent of them 148 (42.3% had a habit of using mobile phone while driving vehicle and 28 (9.7% had experience of driving after drinking alcohol. All the Bajaj, 97(62.6% house car and 58(37.4% taxi unfasten their seat belt while driving. Majority 303 (86.6% followed the recommended speed limit of driving. About 66 (18.9% of them had experience of punishment or warning by traffic polices in the previous 1 year and 77 (22% ever had car accident while driving.

    To examine differences in risky driving behavior and likelihood of traffic crash according to the country of birth of recently licensed young drivers. The groups examined include those born in Australia, those born in Asia, and those born in other countries. The DRIVE study is a prospective cohort study of drivers aged 17-24 years holding their first-year provisional driver license in New South Wales, Australia. Information obtained from 20,822 participants who completed a baseline questionnaire was linked to police-reported traffic crashes. Self-reported risky driving behaviors and police-reported traffic crashes in young drivers. Young drivers who were born in Asian countries were less likely to report engaging in risky driving behaviors than their Australian-born counterparts. The proportion of participants reporting a high level of risky driving was 31.5 percent (95% confidence intervale [CI], 30.8-32.1) among Australian-born drivers compared to 25.6 percent (95% CI, 23.1-28.2) among Asian-born drivers and 30.4 percent (95% CI, 28.4-32.5) among those born in other regions. Asian-born participants had half the risk of a crash as a driver than their Australian-born counterparts (relative risk [RR] 0.55; 95% CI, 0.41-0.75) after adjusting for a number of demographic factors and driving and risk-taking behaviors. The comparative risk was even lower among those aged 17 years (RR 0.29; 95% CI, 0.29-0.75). Risk estimates for people born in other regions did not differ to those for Australian-born respondents. The study highlights the lower level of risky driving and significantly reduced crash risk for Australian drivers born in Asian countries relative to those born locally. Further research is needed to examine factors underlying this reduced risk and the impact of the length of residence in the host country.

    Several studies have related aggressive and risky driving behaviours to accidents. However, the cognitive processes associated with driving aggression have received very little attention in the scientific literature. With the aim of shedding light on this topic, the present research was carried out on a sample of 414 participants in order to validate the Driver's Angry Thoughts Questionnaire (DATQ) with a sample of Spanish drivers and to test the hypothesis of the mediation effect of aggressive and risky driving on the relationship between drivers' angry thoughts and crash-related events. The results showed a good fit with the five-factor model of the questionnaire (Judgmental and Disbelieving Thinking, Pejorative Labelling and Verbally Aggressive Thinking, Revenge and Retaliatory Thinking, Physically Aggressive Thinking, and Coping Self-Instruction). Moreover, slight gender differences were observed in drivers' angry thoughts, with women scoring higher than men (η 2 =0.03). However, younger drivers had higher scores than older drivers in general (η 2 =0.06). Finally, several mediation effects of aggressive driving and risky driving on the relationship between aggressive thinking and the crash-related events were found. Implications of the results for research in traffic psychology and clinical assessment of aggressive drivers as well as limitations of the study are discussed. Copyright © 2017 Elsevier Ltd.

    The present study explored whether aggression, emotional regulation, cognitive inhibition, and attentional bias towards emotional stimuli were related to risky driving behavior (driving errors, and driving violations). A total of 117 applicants for taxi driver positions (89% male, M age=36.59years, SD=9.39, age range 24-62years) participated in the study. Measures included the Ahwaz Aggression Inventory, the Difficulties in emotion regulation Questionnaire, the emotional Stroop task, the Go/No-go task, and the Driving Behavior Questionnaire. Correlation and regression analyses showed that aggression and emotional regulation predicted risky driving behavior. Difficulties in emotion regulation, the obstinacy and revengeful component of aggression, attentional bias toward emotional stimuli, and cognitive inhibition predicted driving errors. Aggression was the only significant predictive factor for driving violations. In conclusion, aggression and difficulties in regulating emotions may exacerbate risky driving behaviors. Deficits in cognitive inhibition and attentional bias toward negative emotional stimuli can increase driving errors. Predisposition to aggression has strong effect on making one vulnerable to violation of traffic rules and crashes. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Drink driving contributes significantly to road traffic injuries. Little is known about the relationship between drink driving and other high-risk behaviors in non-Western countries. The study aimed to assess the relationship between drink driving and other risky behaviors including making phone calls, sending text messages, nonuse of protective gear, and driving against traffic. A cross-sectional survey of risky behavior among undergraduates was conducted. A stratified random sampling method was used to identify young undergraduates who had driven a motorized vehicle in the past year. The Alcohol Use Disorder Identification Test (AUDIT) and other tools developed by researchers were used to identify the risky behaviors. Of 431 respondents, 10.7% had engaged in drink driving in the past 12 months. The most common risky behavior was making phone calls (63.7%), followed by nonuse of helmets (54.7%), driving against traffic (49.2%), nonuse of seat belts (46.8%), and sending text messages (26.1%). Alcohol use was significantly associated with making phone calls (U = 1.148; P < .0001), sending text messages (U = 1.598; P = .021), nonuse of helmets (U = 1.147; P < .0001), driving against traffic (U = 1.234; P < .0001), and nonuse of seat belts (U = 3.233; P = .001). Drink driving was associated with all risky behaviors except nonuse of seat belts (U = 1.842; P = .065). Alcohol use and drink driving were associated with multiple risky driving behaviors. This provides useful insight for policy development and presents additional challenges for traffic injury prevention.

    This study examined the driving behavior of 42 parent-teenager dyads for 18 months, under naturalistic driving conditions. At baseline participants' personality characteristics were assessed. Objective risky driving measures (kinematic risky driving) were captured by accelerometers for the duration of the study. To estimate teenage and parent correlations in kinematic risky driving, separate Poisson regression models were fit for teenagers and parents. Standardized residuals were computed for each trip for each individual. Correlations were obtained by estimating the Spearman rank correlations of the individual average residuals across teenagers and parents. The bootstrap technique was used to estimate the standard errors associated with the parent-teenager correlations. The overall correlation between teenage and parent kinematic risky driving for the 18-month study period was positive, but weak (r=0.18). When the association between parent and teenagers' risky driving was adjusted for shared personality characteristics, the correlation reduced to 0.09. Although interesting, the 95% confidence intervals on the difference between these two estimates overlapped zero. We conclude that the weak similarity in parent-teen kinematic risky driving was partly explained by shared personality characteristics. Published by Elsevier Ltd.

    Young novice drivers are significantly more likely to be killed or injured in car crashes than older, experienced drivers. Graduated driver licensing (GDL), which allows the novice to gain driving experience under less-risky circumstances, has resulted in reduced crash incidence; however, the driver's psychological traits are ignored. This paper explores the relationships between gender, age, anxiety, depression, sensitivity to reward and punishment, sensation-seeking propensity, and risky driving. Participants were 761 young drivers aged 17-24 (M=19.00, SD=1.56) with a Provisional (intermediate) driver's licence who completed an online survey comprising socio-demographic questions, the Impulsive Sensation Seeking Scale, Kessler's Psychological Distress Scale, the Sensitivity to Punishment and Sensitivity to Reward Questionnaire, and the Behaviour of Young Novice Drivers Scale. Path analysis revealed depression, reward sensitivity, and sensation-seeking propensity predicted the self-reported risky behaviour of the young novice drivers. Gender was a moderator; and the anxiety level of female drivers also influenced their risky driving. Interventions do not directly consider the role of rewards and sensation seeking, or the young person's mental health. An approach that does take these variables into account may contribute to improved road safety outcomes for both young and older road users. ©2011 The British Psychological Society.

    There is consistent scientific evidence that professional drivers constitute an occupational group that is highly exposed to work related stressors. Furthermore, several recent studies associate work stress and fatigue with unsafe and counterproductive work behaviors. This study examines the association between stress-related work conditions of Bus Rapid Transport (BRT) drivers and risky driving behaviors; and examines whether fatigue is a mechanism that mediates the association between the two. A sample of 524 male Bus Rapid Transit (BRT) operators were drawn from four transport companies in Bogotá, Colombia. The participants answered a survey which included an adapted version of the Driver Behavior Questionnaire (DBQ) for BRT operators, as well as the Effort-Reward Imbalance and Job Content Questionnaires, the Subjective Fatigue subscale of the Checklist Individual Strength (CIS) and the Need for Recovery after Work Scale (NFR). Utilizing Structural Equation Models (SEM) it was found that risky driving behaviors in BRT operators could be predicted through job strain, effort-reward imbalance and social support at work. It was also found that fatigue and need for recovery fully mediate the associations between job strain and risky driving, and between social support and risky driving, but not the association between effort/reward imbalance (ERI) and risky driving. The results of this study suggest that a) stress related working conditions (Job Strain, Social Support and ERI) are relevant predictors of risky driving in BRT operators, and b) that fatigue is the mechanism which links another kind of stress related to working conditions (job strain and low social support) with risky driving. The mechanism by which ERI increases risky driving in BRT operators remains unexplained. This research suggests that in addition to the individual centered stress-reduction occupational programs, fatigue management interventions aimed to changing some working conditions may reduce

    Entry of terms reflective of extreme risky driving behaviors into the YouTube website yields millions of videos. The majority of the top 20 highly subscribed automotive YouTube websites are focused on high-performance vehicles, high speed, and often risky driving. Moreover, young men are the heaviest users of online video sharing sites, overall streaming more videos, and watching them longer than any other group. The purpose of this article is to review the literature on YouTube videos and risky driving. A systematic search was performed using the following specialized database sources-Scopus, PubMed, Web of Science, ERIC, and Google Scholar-for the years 2005-2015 for articles in the English language. Search words included "YouTube AND driving," "YouTube AND speeding," "YouTube AND racing." No published research was found on the content of risky driving videos or on the effects of these videos on viewers. This literature review presents the current state of our published knowledge on the topic, which includes a review of the effects of mass media on risky driving cognitions; attitudes and behavior; similarities and differences between mass and social media; information on the YouTube platform; psychological theories that could support YouTube's potential effects on driving behavior; and 2 examples of risky driving behaviors ("sidewalk skiing" and "ghost riding the whip") suggestive of varying levels of modeling behavior in subsequent YouTube videos. Every month about 1 billion individuals are reported to view YouTube videos (ebizMBA Guide 2015 ) and young men are the heaviest users, overall streaming more YouTube videos and watching them longer than women and other age groups (Nielsen 2011 ). This group is also the most dangerous group in traffic, engaging in more per capita violations and experiencing more per capita injuries and fatalities (e.g., Parker et al. 1995 ; Reason et al. 1990 ; Transport Canada 2015 ; World Health Organization 2015 ).

    Full Text Available South Africa has one of the highest incidences of road accidents in the world. Most accidents are avoidable and are caused by driver behaviour and errors. The purpose of this article was to identify the riskiest driver behaviours in commercial fleets in South Africa, to determine the business impact of such behaviour, to establish a framework for the management of risky driver behaviour and to test the framework by applying a leading commercial driver behaviour management system as a case study. The case study comprised three South African commercial fleets. Using data from these fleets, critical incident triangles were used to determine the ratio data of risky driver behaviour to near-collisions and collisions. Based on managing the riskiest driver behaviours as causes of more serious incidents and accidents, the results indicated that through the implementation of an effective driver risk management system, risky incidents were significantly reduced.

    2012-02-17

    This work proposes a critical, non systematic, review of the three main lines of health policy interventions to deal with risky behaviours, such as over-eating, smoking, sedentary lives, and excess alcohol drinking, namely: i) the release of information on health risks and consequences; ii) the use of incentives; and iii) direct policy intervention in markets, through regulation and taxation. First, the health and economic impact of the risky behaviours epidemics are briefly described. Then a critical review follows on the evidence existing on the effectiveness of each type of intervention. The review will also highlight the public health approach staying beyond each type of policy on risky behaviours and critically consider them within the context of more general health and social policy interventions.

    Drug and alcohol use are known to increase the risk of traffic accidents, especially among youth. However, the association between habitual drug use and the adoption of risky driving behavior is not well known. The aim of this study was to identify and quantify the association between habitual drug use and involvement in risky driving practices overall and by gender among university students. A cross sectional study was conducted. The study population was composed of 559 car drivers younger than 31 years who completed an online questionnaire during the 2011-2012 academic year. Among other factors, the questionnaire assessed the following items: habitual drug consumption (20 or more days) during the last year and involvement in other risky driving practices during the last month. A total of 27.7% of students reported they had used drugs regularly during the last year. Drug use was associated with a higher frequency of involvement in risky driving practices. In men, the factors most strongly associated with drug consumption were speeding, driving under influence of alcohol, and feeling drowsy while driving. In women, drug consumption was mainly associated with smoking while driving, drunk driving, and driving without rest. The results of our study support the hypothesis that habitual drug use is associated with an increased frequency of risky driving behavior. Copyright © 2014 SESPAS. Published by Elsevier Espana.

    The link between economic empowerment and high risky sexual behaviour has been debated by different scholars in various settings. However, no consistently clear connection between poverty and lack of education has been found regarding engagement in risky sexual behaviour. Also, not much research has been done to examine the strength of these relationships for adolescents and women. The objectives of this study were to assess the relationship between female economic empowerment and risky sexual behaviour in Africa. Using the latest Demographic and Health Surveys Data (DHS 2011-2014) from Gabon, Mozambique, Sierra Leone and Zambia, univariate, bivariate and multivariate analysis was done on women aged 15 to 49 to examine the patterns of and differences in the association between women's economic empowerment and risky sexual behaviour. The findings both at community and individual level indicate that empowered women (higher education and wealth household) and adolescents aged 15 to 19 are highly significantly associated with engagement in high risky behaviour. The result of this study stresses the need to look further than individual factors in the quest to resolve risky sexual behaviour in Africa. The interrelations between female economic empowerment and engagement in risky sexual behaviour are more complicated and less straightforward than usually presumed.

    2014-01-01

    Grounded in self-determination theory, obsessive passion for an activity has been associated with increased risky behaviour and rigid persistence, both symptomatic of dependence. However, it is unknown whether obsessive passion may predict the development of dependence, and furthermore, theoretically important relationships between basic need satisfaction, passion, exercise dependence and subsequent risky behaviour have not been fully explored. A sample of 100 professional dancers (50(fs); 50(ms); Mage = 20.88; SD = 2.69) completed self-ratings of risk-related behaviours (doctor visits; following treatment, and warming up), passion for dance and dance dependence. Findings supported the maladaptive nature of obsessive passion in relation to risky behaviour and as predicted dance dependence mediated this relationship. Interestingly, need satisfaction was positively related to both obsessive passion and harmonious passion. Results are discussed in the light of self-determination theory and dysfunctions of obsessive passion, suggesting that professional dancers are at risk of employing maladaptive behaviours if high in obsessive passion, which may be detectable via symptoms of dance dependence.

    The aim of this article is to investigate the impact of ART perception on risky sexual behaviours in Botswana. Using binary logistic regression analysis controlling for individual characteristics, the results tend to support the hypothesis that ART misconceptions do not necessarily increase risky sexual behaviours. In particular, the study findings suggest the belief that ARVs cure HIV and AIDS and that people on ARVs should not always use condoms do not necessarily lead to increased risky sexual behaviours, particularly among women. Gender differentials exist in the perceived sexual risk resulting from the use of ART. Risky sexual behaviours increase for women who, wrongly, believed that ARVs cure HIV and AIDS and people on ARVs should not always use condoms. Although there is evidence to suggest ART perceptions do not necessarily lead to increased risky sexual behaviours, HIV and AIDS prevention programmes are needed to strengthen their information, education and communication intervention component that can address misconceptions about ART treatment and provide correct information that is gender-appropriate.

    The aim of the study was to examine the relative importance of young novice drivers' family climate on their driving behavior. A sample of young novice drivers (N=171) between the age of 17 and 24, who held their permanent (or temporary) driver's license for no longer than one year, participated. The questionnaire included items related to the participants' family climate, 3 socio-cognitive determinants (i.e., attitude, locus of control and social norm), and risky driving behaviors. We expected both family climate and the socio-cognitive determinants to exert a direct effect on risky driving. Furthermore we hypothesized that the socio-cognitive determinants would moderate the impact of family climate on risky driving. The results showed that the effect of family climate on risky driving only originated from one single factor (i.e., noncommitment). Besides that, the results confirmed the importance of the three socio-cognitive determinants to the degree that attitude, locus of control, and social norm significantly predicted the self-reported risky driving. In line of what we hypothesized, attitude moderated the relationship between noncommitment and risky driving. Lastly, we found an unexpected three-way interaction which indicated that locus of control moderated the relation between noncommitment and risky driving only when young drivers' attitude was risk-supportive. We recommend scholars and practitioners to take into account the interaction between external sources of influence (such as an individual's family climate) and more personally oriented dispositions (such as an individual's attitude, social norm and locus of control) when trying to explain and change young novices' risky driving.

    This study examines predictors of later risky driving behavior in children with attention-deficit/hyperactivity disorder (ADHD). Stepwise logistic regression and receiver operating characteristic (ROC) analysis were used to explore baseline predictors of risky driving behavior for adolescents who completed the 8-year follow-up assessment in the Multimodal Treatment Study of Children with Attention-Deficit/Hyperactivity Disorder (MTA). Stepwise logistic regression analysis explained 19% of the total variance in risky driving behavior. Increased likelihood of risky driving behavior was associated with parental history of conduct disorder, low parental monitoring and supervision, and increased age. ROC analysis identified discriminative predictors for adolescents older and younger than 16 years of age at follow-up. The most discriminative predictors of later risky driving behavior were parental stress at baseline (for children 16 years or older) and increased child-rated parental protectiveness (for children less than 16 years old). Risky driving behavior was significantly predicted by baseline characteristics for the MTA cohort. Aspects of parenting behavior (or the child's perception of them), including parental stress levels, parental protectiveness, and parental levels of monitoring and supervision, were most informative in predicting these outcomes. Our results suggest that interventions to reduce high-risk behaviors in these high-risk children with ADHD might involve targeted parenting interventions.

    The use of the social marketing approach for public health issues is increasing. This approach uses marketing concepts borrowed from the principles of commercial marketing to promote beneficial health behaviors. In this qualitative study, four focus groups involving 42 participants were used in consumer research to explore taxi drivers' views on the driving situation and the determinants of risky driving behaviors in Tehran, as well as to gather their ideas for developing a social marketing program to reduce risky driving behaviors among taxi drivers in Tehran, Iran. Participants were asked to respond to questions that would guide the development of a marketing mix, or four Ps (product, price, place and promotion). The discussions determined that the program product should involve avoiding risky driving behaviors through increased attention to driving. They pointed out that developing and communicating with a well-designed persuasive message meant to draw their attention to driving could affect their driving behaviors. In addition, participants identified price, place and promotion strategies. They offered suggestions for marketing nonrisky driving to the target audience. The focus group discussions generated important insights into the values and the motivations that affect consumers' decisions to adopt the product. The focus group guided the development of a social marketing program to reduce risky driving behaviors in taxi drivers in Tehran, Iran. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Smorti, Martina; Guarnieri, Silvia

    2016-01-01

    The present study examined the contribution of impulsiveness and aggressive and negative emotional driving to the prediction of traffic violations and accidents taking into account potential mediation effects. Three hundred and four young drivers completed self-report measures assessing impulsiveness, aggressive and negative emotional driving, driving violations, and accidents. Structural equation modeling was used to assess the direct and indirect effects of impulsiveness on violations and accidents among young drivers through aggressive and negative emotional driving. Impulsiveness only indirectly influenced drivers' violations on the road via both the behavioral and emotional states of the driver. On the contrary, impulsiveness was neither directly nor indirectly associated with traffic accidents. Therefore, impulsiveness modulates young drivers' behavioral and emotional states while driving, which in turn influences risky driving.

    This study assessed the impact of an education program on knowledge of sleepiness and driving behaviour in young adult drivers and their performance and behaviour during simulated night driving. Thirty-four participants (18-26 years old) were randomized to receive either a four-week education program about sleep and driving or a control condition. A series of questionnaires were administered to assess knowledge of factors affecting sleep and driving before and after the four-week education program. Participants also completed a two hour driving simulator task at 1am after 17 h of extended wakefulness to assess the impact on driving behaviour. There was an increase in circadian rhythm knowledge in the intervention group following the education program. Self-reported risky behaviour increased in the control group with no changes in other aspects of sleep knowledge. There were no significant differences in proportion of intervention and control participants who had microsleeps (p ≤ .096), stopped driving due to sleepiness (p = .107), recorded objective episodes of drowsiness (p = .455), and crashed (p = .761), although there was a trend towards more control participants having microsleeps and stopping driving. Those in the intervention group reported higher subjective sleepiness at the end of the drive [M = 6.25, SD = 3.83, t(31) = 2.15, p = .05] and were more likely to indicate that they would stop driving [M = 3.08, SD = 1.16, t(31) = 2.24, p = .04]. The education program improved some aspects of driver knowledge about sleep and safety. The results also suggested that the education program lead to an increased awareness of sleepiness. Education about sleep and driving could reduce the risk of drowsy driving and associated road trauma in young drivers, but requires evaluation in a broader sample with assessment of real world driving outcomes.

    2018-01-01

    Full Text Available Background: Over a million people globally acquire sexually transmitted infections (STI every day mainly through unprotected sexual contact. While the consequences of risky sexual behaviour are well documented, the literature on young educated women's perceptions of, and narratives about risky sexual behaviour is limited, and thus, it is difficult to fathom from available sources why such behaviour persists. This study examined the prevalence of sexual risk-taking and assessed female University students' knowledge of the consequences of unprotected sex and reasons why such behaviour persists. Paradoxes between their narratives and risky sexual behaviour were discussed. Methods: The study adopted a mixed study design involving a survey of 420 students selected using cluster random sampling, 20 in-depth interviews and 5 focus group discussions. The analysis of the quantitative data involves the use of descriptive and inferential statistics, while thematic content analysis was used to analyse the qualitative data. Results: High prevalence of unprotected sexual intercourse was reported and was not associated with age, year of study, place of residence and religion. The narratives of participants indicate that female university students were aware of the risks associated with unprotected sex. Participants generally condemned sexual risk-taking and asserted that freedom, peer influence, poverty, ignorance, lack of sex education, civilisation, promiscuity, and satisfying sexual urge were the reasons for the persistent risky sexual behaviour among female university students. Also, perceived reduced fun associated with condom use, nourishment of marital expectations, and equivalence of unprotected sex with trust are among the reasons for persistent sexual risk-taking among female university students. Conclusion: Our findings show that female students practice risky sexual behaviour despite having knowledge of its consequences. Change in sexual behaviour

    An interest exists in understanding why adolescents partake in risky sexual behaviours, as well as the risk and protective practices associated with risky sexual behaviour. The aim of this study was to investigate the moderator effect of future time perspective in the relationship between self-efficacy and risky sexual behaviour. A random cluster consisting of 467 learners from English medium high schools of central South Africa participated in this study. The participants' risky sexual behaviour, self-efficacy and future time perspective were measured with the Perceptions of HIV/AIDS Risk Survey, Generalised Perceived Self-efficacy Scale and the Zimbardo Time Perspective Inventory, respectively. Product term regression analysis was performed. It was found that both self-efficacy and future time perspective were negatively related to risky sexual behaviour. No moderating effect was found for future time perspective in the relationship between self-efficacy and risky sexual behaviour. Self-efficacy and future time perspective were identified as qualities that protect adolescents from engaging in risky sexual behaviours. This finding can be useful in developing prevention programmes. Intervention programmes aimed at the youth should foster a sense of hope and possibility about the future and the development of goals and aspirations to prevent risky behaviour.

    The present study explored the relationship between risky cybersecurity behaviours, attitudes towards cybersecurity in a business environment, Internet addiction, and impulsivity. 538 participants in part-time or full-time employment in the UK completed an online questionnaire, with responses from 515 being used in the data analysis. The survey included an attitude towards cybercrime and cybersecurity in business scale, a measure of impulsivity, Internet addiction and a 'risky' cybersecurity behaviours scale. The results demonstrated that Internet addiction was a significant predictor for risky cybersecurity behaviours. A positive attitude towards cybersecurity in business was negatively related to risky cybersecurity behaviours. Finally, the measure of impulsivity revealed that both attentional and motor impulsivity were both significant positive predictors of risky cybersecurity behaviours, with non-planning being a significant negative predictor. The results present a further step in understanding the individual differences that may govern good cybersecurity practices, highlighting the need to focus directly on more effective training and awareness mechanisms.

    Young adults and teens are documented as the riskiest drivers on the road, and newer issues such as texting and driving are a growing concern. This study sought to determine the risk perceptions of young adults regarding various driving behaviors, their past experiences, how their social circles are structured, and how this might affect their driving. This study conducted qualitative research with 25 college undergraduate students to determine their peer and social influences regarding distracted driving. Data were analyzed and related to the health belief model and past research on social influence. Though most participants felt that their behaviors were set after learning to drive, they were, in fact, quite susceptible to the influence of those in their social circles (e.g., fear of judgment and accountability) and, more broadly, to social norms. Texting and driving was the largest and most topical distracted driving issue and was also identified as very difficult to stop due to perceived barriers and the idea that intervening is rude. Participants identified low perceived susceptibility and severity (perceived threat) for a number of risky driving behaviors, including texting and driving. Training is needed to encourage people to intervene and speak up regarding behaviors other than drinking and driving, and cues to action and campaigns should target intervention to increase self-efficacy, as well as norms, susceptibility, and common rationalizations for risky behavior.

    Within a research project on the role played by human factors on road accidents, the aim of the present study is to evaluate, in young adults, the relationships between driver behaviour and personality factors as well as to assess the neuroendocrine correlates of psychological and behavioural factors investigated. Another aim is to estimate in what measure the performance levels are affected by demographic, psychological and chronobiological variables. It has been found a positive relation between highway code violations, extroversion trait of personality and Sensation Seeking scores, so confirming that this component of personality can affect risky behaviour. Furthermore the subjects more oriented to morningness chronotype were found to be prone to adopt safe driving behaviour. Regarding the relations of the neuroendocrine parameters and driving behaviour a positive correlation was observed between dopamine levels and frequency of driving violations while a negative relationship was found between adrenaline levels and frequency of driving errors. In conclusion the identification of psycho-physiological variables related to driving risky behaviour might be a useful instrument to design traffic safety programs tailored to high risk subjects.

  8. Acute disinhibiting effects of alcohol as a factor in risky driving behavior

    Automobile crash reports show that up to 40% of fatal crashes in the United States involve alcohol and that younger drivers are over-represented. Alcohol use among young drivers is associated with impulsive and risky driving behaviors, such as speeding, which could contribute to their over-representation in alcohol-related crash statistics. Recent laboratory studies show that alcohol increases impulsive behaviors by impairing the drinker’s ability to inhibit inappropriate actions and that this effect can be exacerbated in conflict situations where the expression and inhibition of behavior are equally motivating. The present study tested the hypothesis that this response conflict might also intensify the disruptive effects of alcohol on driving performance. Fourteen subjects performed a simulated driving and a cued go/no-go task that measured their inhibitory control. Conflict was motivated in these tasks by providing equal monetary incentives for slow, careful behavior (e.g., slow driving, inhibiting impulses) and for quick, abrupt behavior (fast driving, disinhibition). Subjects were tested under two alcohol doses (0.65 g/kg and a placebo) that were administered twice: when conflict was present and when conflict was absent. Alcohol interacted with conflict to impair inhibitory control and to increase risky and impaired driving behavior on the drive task. Also, individuals whose inhibitory control was most impaired by alcohol displayed the poorest driving performance under the drug. The study demonstrates potentially serious disruptions to driving performance as a function of alcohol intoxication and response conflict, and points to inhibitory control as an important underlying mechanism.

    We investigated the moderating effects of drug/alcohol use in the past 3 months on the relationships of peer influence, parental permissiveness, and teen disposition (i.e., achievement motivation, attitude toward school, and value placed on health) with adolescent risky sexual behaviour. Participants were 207 adolescents receiving psychiatric care. Substance use did not moderate the relationship between adolescent disposition and risky sex. By contrast, peer influence and parental permissiveness were linked to risky sex but only for teens who reported using drugs/alcohol. Controlling for other predictors in the model, negative peer influence explained 21% and parental permissiveness explained 13% of the variance in risky sex among substance users, but less than half of 1% of the variance among non-substance users. The disinhibiting effects of substance use on decision-making and the need for effective parental monitoring to reduce opportunities for risk behaviour are discussed.

    2016-01-01

    We hypothesised that resiliency may protect adolescents against risky behaviours, and that both the practicing of sports, and gender are moderating variables in relationships between resiliency and risky behaviours. The study included 18-year-old pupils from a selection of secondary schools (n = 556). A total of 188 individuals practiced competitive sports and the remaining 368 participants were non-athletes. The participants were examined with the Resiliency Assessment Scale for Children and Adolescents (SPP-18) and with a survey containing questions and statements related to high-risk "experiments with adulthood". Adolescent athletes showed higher levels of resiliency than their peers. The power of the "Determination and Persistence in Action" effect on "Alcohol" scale differed significantly between male athletes and male non-athletes. Only in the athletes groups were higher scores on this scale reflected by lower values on the "Drugs" scale. Moreover, it is possible to observe differences in undertaking risky behaviour between male and female athletes. The analysis of risky sexual behaviour suggests that sport is a risk factor for men, and a protective factor for women. These data suggest that consistent prophylactic and psycho-educative activities, with a special attention to differences between genders, should be provided to all the adolescents, irrespective of their sport performance levels.

    This paper explores problematic Internet gaming in the context of other forms of risky behaviour. The basic premise is that children and adolescents at risk will display different types of risky behaviour in various settings. Children and adolescents (N=1150) were surveyed about (cyber)violence, problematic gaming (habits, motives and symptoms), self-disclosure via Facebook and self-esteem. Regular gamers were more violent both face-to-face and via the Internet, and were more prone to problematic gaming than occasional gamers. Those who played games for more than five hours per day (9% of respondents) were classified as potentially problematic gamers. They experienced and committed more violence both face-to-face and via the Internet, were more involved in self-disclosure and had more problematic gaming symptoms than those who played for less than five hours a day, but these groups did not differ in self-esteem. Participants could choose from a list of eight different motives for their gaming; those motivated by peer communication, a sense of control, relaxation, conformism, self-efficacy and to distract from problems reported more symptoms of problematic gaming than those not motivated by these factors. Gender, age, self-esteem, self-disclosure and committing violence contributed to explaining the variance in problematic gaming, accounting for about 26% of its variance. Boys, lower self-esteem, more self-disclosure and committing both types of violence more regularly were connected with reporting more symptoms of problematic gaming. The results will be discussed in the context of a general proneness to risky behaviour. Committing violence against peers (both traditional and cyber) predicts significantly problematic gaming. This supports the premise that children and adolescents at risk are prone to exhibiting different forms of risky behaviour in different settings.

    2012-01-01

    Purpose Teenage risky driving may be due to teenagers not knowing what is risky, preferring risk, or the lack of consequences. Elevated gravitational-force (g-force) events, caused mainly by hard braking and sharp turns, provide a valid measure of risky driving and are the target of interventions using in-vehicle data recording and feedback devices. The effect of two forms of feedback about risky driving events to teenagers only or to teenagers and their parents was tested in a randomized controlled trial. Methods Ninety parent-teen dyads were randomized to one of two groups: (1) immediate feedback to teens (Lights Only); or (2) immediate feedback to teens plus family access to event videos and ranking of the teen relative to other teenage drivers (Lights Plus). Participants’ vehicles were instrumented with data recording devices and events exceeding 0.5 g were assessed for two weeks of baseline and 13 weeks of feedback. Results Growth analysis with random slopes yielded a significant decrease in event rates for the Lights Plus group (slope = −.11, p teenagers did not. Implications and Contribution Reducing elevated g-force events due to hard stops and sharp turns could reduce crash rates among novice teenage drivers. Using materials from the DriveCam For Families Program we found that feedback to both teens and parents significantly reduced rates, while feedback only to teens did not. PMID:23375825

    The present study aims to compare differences in reported risky driving behaviors of drivers - males and females - having and not having Attention Deficit Hyperactivity Disorder (ADHD), by using a checklist of driving behaviors based on the Driving Behavior Questionnaire (DBQ). Unlike the studies which employ the DBQ by asking the subjects to fill the questionnaire once, in this present study, the participants were asked to report their behaviors on a daily basis for 30 consequent days. The checklist included two factors of risky driving behavior: Violation and Faults. Thirty-eight drivers - 10 males and 9 females with ADHD, and 9 males and 10 females without ADHD (N-ADHD) as control groups - participated in the study. The results showed that the mean of the unsafe behaviors of ADHD was higher, i.e., less safe driving, compared to that of N-ADHD. However, a statistically significant effect was found only between male ADHD and male N-ADHD for the Faults. In order to check the effect of the length of the study, the 30 days duration of the research was divided into three consecutive periods. The reported driving habits of the female ADHD showed safer behaviors than those of the males. Unlike the findings of N-ADHD of both genders, which showed a tendency towards safer driving reports in the three periods, both genders of the ADHD showed higher rates of Faults, i.e., a decrease in safety driving reports, in the three periods. The findings suggest that ADHD drivers differ from the N-ADHD drivers in making driving mistakes, i.e., Faults, due to their lack of sustained attention, but not in making Violations. However, some of the results in the present study were not very strong. Possible explanations for this as well as methodological considerations are discussed, and further research is suggested.

    Wishart, Darren; Somoray, Klaire; Evenhuis, Amanda

    2017-12-01

    Introduction Within many industrialized countries, the leading cause of worker fatalities and serious injuries can be attributed to road trauma. In non-occupational research, high levels of sensation seeking personality, and specifically thrill and adventure seeking, have been associated with risky driving behaviors. In work driving literature, high organizational safety climate has been associated with reduced risky driving in work drivers. However, the extent that factors such as safety climate and thrill seeking interact in regard to work driving safety remains unclear, and the current research examined this interaction. Methods A total of 1,011 work drivers from four organizations participated in the research. Surveys were distributed online and hardcopies were sent via mail. The survey included measures of thrill and adventure seeking, safety climate and work-related driving behaviors, as well as questions relating to participant demographics and information about their work driving. Results The results demonstrated that safety climate significantly moderated the effect of thrill and adventure seeking trait on driving errors, driving violations, and driving while fatigued. Conclusion These results suggest that the development of a strong safety climate has the potential to improve work driving safety outcomes by reducing the impact of particular personality traits such as thrill seeking within an organizational context. Practical application To improve work driving safety, organizations and management need to develop strategies to encourage and foster positive work driving safety climate, particularly within work settings that may attract thrill and adventure seeking employees.

    Full Text Available The purpose of this meta-analysis was to assess the association between risky sexual behaviour and level of education and economic status in male youth. Previous tests of the association of risky sexual behaviour with levels of education and economic status have yielded inconsistent results. Using data from 26 countries, from both within and outside Africa, we performed a meta-analysis with a specific focus on male youths’ risky sexual behaviour. We applied a random effects analytic model and calculated a pooled odds ratio. Out of 19,148 males aged 15–24 years who reported having sexual intercourse in the 12 months preceding the survey, 75% engaged in higher-risk sex. The proportion of higher-risk sex among male youth aged 15–19 years was nearly 90% in 21 of the 26 countries. The pooled odds ratio showed a statistically significant association of higher-risk sex with male youth younger than 20 years, living in urban centers, well educated, and of a high economic status. The overall proportion of condom use during youths’ most recent higher-risk sexual encounter was 40% and 51% among 15–19-year-olds and 20–24-year-olds, respectively. Our findings suggest that male youth’s socioeconomic status is directly related to the likelihood that they practice higher-risk sex. The relationship between income and sexual behaviour should be explored further.

    Full Text Available The aim of this study was to determine the risky health behaviors and to raise the awareness of adolescents (attending high school education about prevention of risky behaviors and solutions by the effect of module-based training courses (about reproductive health and birth control, sexually transmitted infections, harmful habits, psychosocial behavior. Being planned as cross-sectional, this study was performed between September 2013-June 2014 in three states and a private high school in Zonguldak and conducted with a group of students aged between 14 and 19.926 students have participated before the training and 534 students have participated after training. It was seen that the mean scores of ‘The Adolescent Risk-Taking Questionnaire', ‘The Adolescent's Attitudes Towards Violence Scale' and ‘taking risk about social status', ‘traffic', ‘subtance use' subscales have decreased after the risk prevention trainings. The means scores of ‘Adolescent Coping with Problems Scale', ‘Nutrition Behaviour Scale' and ‘Nutrition Attitude Scale' have raised. Hence, the scores of domains reflecting adolescent health perception such as hygiene, sleep and exercise have raised while the scores of somatic symptoms domain, such as abdominal pain, headache, and fatigue have been failed. Consequently, it was determined that the training courses about risky health behaviours were effective in preventing risky health behaviors and creating positive health perceptions of adolescents.

    Full Text Available Abstract Background The association between risky sexual behaviours and substance uses among Ghanaian youth were investigated. Methods An in-school cross-sectional representative survey was conducted among 12-18-year- old youth in Ghana in 2008 (N = 1195, response rate =90%. Logistic regression analyses were employed to investigate the association between substance use (tobacco use, drunkenness, marijuana use and other drug uses and risky sexual behaviours (sexual debut, condom use and number of sexual partners. Results Of all youth, 25% (28% boys and 23% girls were sexually experienced. The mean age for first sexual intercourse was 14.8 years (14.4 years for boys and 15.1 years for girls. Among the sexually experienced, 31% had multiple sexual partners. Older age (OR = 3.4, 95% CI = 1.7-3.4 and rural residency (OR = 1.5, 95% CI = 1.1-2.1 were independently associated with sexual debut while only older age (OR = 2.4, 95% CI = 1.7-3.4 was associated with condom use. Additionally, smoking (OR = 3.7, 95% CI = 2.0-6.8, tawa use (OR = 2.4, 95% CI = 1.3-4.7, tobacco use (OR = 2.8, 95% CI = 1.7-4.7 drunkenness (OR = 1.7, 95% CI = 1.1-2.8 and marijuana use (OR = 3.3, 95% CI = 1.6-7.0 were independently associated with sexual debut. Furthermore, all substance uses studied were associated with having one or multiple sexual partners. Conclusion Substance use seems to be a gateway for risky sexual behaviours among Ghanaian youth. Public health interventions should take into account the likelihood of substance use among sexually experienced youth.

    Roadway incidents are the leading cause of work-related death in the United States. The objective of this research was to evaluate whether two types of feedback from a commercially available in-vehicle monitoring system (IVMS) would reduce the incidence of risky driving behaviors in drivers from two companies. IVMS were installed in 315 vehicles representing the industries of local truck transportation and oil and gas support operations, and data were collected over an approximate two-year period in intervention and control groups. In one period, intervention group drivers were given feedback from in-cab warning lights from an IVMS that indicated occurrence of harsh vehicle maneuvers. In another period, intervention group drivers viewed video recordings of their risky driving behaviors with supervisors, and were coached by supervisors on safe driving practices. Risky driving behaviors declined significantly more during the period with coaching plus instant feedback with lights in comparison to the period with lights-only feedback (ORadj=0.61 95% CI 0.43-0.86; Holm-adjusted p=0.035) and the control group (ORadj=0.52 95% CI 0.33-0.82; Holm-adjusted p=0.032). Lights-only feedback was not found to be significantly different than the control group's decline from baseline (ORadj=0.86 95% CI 0.51-1.43; Holm-adjusted p>0.05). The largest decline in the rate of risky driving behaviors occurred when feedback included both supervisory coaching and lights. Supervisory coaching is an effective form of feedback to improve driving habits in the workplace. The potential advantages and limitations of this IVMS-based intervention program are discussed.

    To explore whether measurements of self-regulatory mechanisms and cognition predict driving behaviour after an acquired brain injury (ABI). Consecutive follow-up study. At baseline participants included 77 persons with stroke and 32 persons with a traumatic brain injury (TBI), all of whom completed a multidisciplinary driving assessment (MDA). A follow-up cohort of 34 persons that succeeded the MDA was included. Baseline measurements: Neuropsychological tests and measurements of self-regulatory mechanisms (BRIEF-A and UPPS Impulsive Behaviour Scale), driving behaviour (DBQ) and pre-injury driving characteristics (mileage, compensatory driving strategies and accident rates). Follow-up measurements: Post-injury driving characteristics were collected by mailed questionnaires from the participants who succeeded the MDA. A MDA, which included a medical examination, neuropsychological testing and an on-road driving test, was considered in the decision for or against granting a driver's license. Self-regulatory mechanisms and driving behaviour were examined for research purposes only. At baseline, self-regulatory mechanisms were significantly associated to aberrant driving behaviour, but not with neuropsychological data or with the outcome of the on-road driving test. Aspects of self-regulation were associated to driving behaviour at follow-up. It is recommended that self-regulatory measurements should regularly be considered in the driving assessments after ABI.

    The apparently higher crash risk among individuals who use cell phones while driving may be due both to the direct interference of cell phone use with the driving task and tendencies to engage in risky driving behaviors independent of cell phone use. Measurements of actual highway driving performance, self-reported aberrant driving behaviors as measured by the Manchester Driver Behavior Questionnaire (DBQ), and attitudes toward speeding, passing behaviors and relative concern about being involved in a crash were assessed. Individuals who reported frequently using cell phones while driving were found to drive faster, change lanes more frequently, spend more time in the left lane, and engage in more instances of hard braking and high acceleration events. They also scored higher in self-reported driving violations on the DBQ and reported more positive attitudes toward speeding and passing than drivers who did not report using a cell phone regularly while driving. These results indicate that a greater reported frequency of cell phone use while driving is associated with a broader pattern of behaviors that are likely to increase the overall risk of crash involvement.

    Bagdadi, Omar; Várhelyi, András

    2011-07-01

    This study uses continuously logged driving data from 166 private cars to derive the level of jerks caused by the drivers during everyday driving. The number of critical jerks found in the data is analysed and compared with the self-reported accident involvement of the drivers. The results show that the expected number of accidents for a driver increases with the number of critical jerks caused by the driver. Jerk analyses make it possible to identify safety critical driving behaviour or "accident prone" drivers. They also facilitate the development of safety measures such as active safety systems or advanced driver assistance systems, ADAS, which could be adapted for specific groups of drivers or specific risky driving behaviour.

    This study examined the role of stress as a mediator of the relationship between prior drug addiction and current high-risk sexual behaviour. Eight hundred twenty women aged 18 to 30 years, who received care at community-based family planning clinics, were interviewed using the Composite International Diagnostic Interview and the Sexual Risk Behavior Assessment Schedule. They also completed the brief version of the Self-Control Scale as a measure of problem-solving strategies and measures of recent stressful events, daily hassles and ongoing chronic stress. Regardless of addiction history, stress exposure during the previous 12 months was associated with risky sexual behaviour during the previous 12 months. Structural equation modelling revealed that 12-month stress levels mediated the relationship between past drug addiction and 12-month high-risk sexual behaviours, as well as the negative relationship between problem-solving strategies and high-risk sexual behaviours. Problem-solving strategies did not moderate the relationship between drug addiction and high-risk sexual behaviours. These findings suggest that stress management training may help reduce risky behaviour among young, low-income women. Copyright © 2014 John Wiley & Sons, Ltd.

    Full Text Available Previous research suggests that the market driving behaviour of firms is linked to exceptional performance. However, the elements of market driving, its antecedents and outcomes, have so far not been empirically measured. The primary objectives of this study are to identify factors that describe market driving, develop a conceptual model, and then consider influencing factors and performance indicators drawn from the entrepreneurship and marketing literature. The model has been empirically tested using a sample of managers in the South African healthcare industry. A fully structured questionnaire was used to address the objective of this study. The realised sample of n=328 was used to analyse the conceptual model applying a partial least squares path modelling approach (PLS-PM. The results revealed that market driving is a firm behaviour and is distinguished by three distinct concepts: market sensing, influencing customer preferences and alliance formation. Three out of four antecedents: strategic orientation, entrepreneurial capital and entrepreneurial behaviour, influenced market driving ability positively. The study also demonstrated that market driving behaviour positively influences firm performance and relative competitive strength

In the presentstudy two demographic variables (gender and age, two non-psychological driving-experiencerelated variables (annual mileage and legal driving experience in years and aggressiveness asa personality trait (including behavioural and affective components as psychological variableof individual differences were examined as potential predictors of aggressive driving. The aimof the study was to find out the best predictors of aggressive driving behaviour. The study wasbased on an online survey, and 228 vehicle drivers in Latvia participated in it. The questionnaireincluded eight-item Aggressive Driving Scale (Bone & Mowen, 2006, short Latvian versionof the Buss-Perry Aggression Questionnaire (AQ; Buss & Perry, 1992, and questions gainingdemographic and driving experience information. Gender, age and annual mileage predictedaggressive driving: being male, young and with higher annual driving exposure were associatedwith higher scores on aggressive driving. Dispositional aggressiveness due to anger componentwas a significant predictor of aggressive diving score. Physical aggression and hostility wereunrelated to aggressive driving. Altogether, the predictors explained a total of 28% of thevariance in aggressive driving behaviour. Findings show that dispositional aggressiveness,especially the anger component, as well as male gender, young age and higher annual mileagehas a predictive validity in relation to aggressive driving. There is a need to extend the scope ofpotential dispositional predictors pertinent to driving aggression.

    Full Text Available Climate change is receiving increasing attention in recent years. The transportation sector contributes substantially to increased fuel consumption, greenhouse gas (GHG emissions, and poor air quality, which imposes a serious respiratory health hazard. Road transport has made a significant contribution to this effect. Consequently, many countries have attempted to mitigate climate change using various strategies. This study analysed and compared the number of policies and other approaches necessary to achieve reduced fuel consumption and carbon emission. Frequency aggregation indicates that the mitigation policies associated with driving behaviours adopted to curtail this consumption and decrease hazardous emissions, as well as a safety enhancement. Furthermore, car-sharing/carpooling was the least investigated approach to establish its influence on mitigation of climate change. Additionally, the influence of such driving behaviours as acceleration/deceleration and the compliance to speed limits on each approach was discussed. Other driving behaviours, such as gear shifting, compliance to traffic laws, choice of route, and idling and braking style, were also discussed. Likewise, the influence of aggression, anxiety, and motivation on driving behaviour of motorists was highlighted. The research determined that driving behaviours can lead to new adaptive driving behaviours and, thus, cause a significant decrease of vehicle fuel consumption and CO2 emissions.

    Drivers' behaviors such as violations and errors have been demonstrated to predict crash involvement among young Omani drivers. However, there is a dearth of studies linking risky driving behaviors to the personality of young drivers. The aim of the present study was to assess such traits within a sample of young Omani drivers (as measured through the behavioral inhibition system [BIS] and the behavioral activation system [BAS]) and determine links with aberrant driving behaviors and self-reported crash involvement. A cross-sectional study was conducted at the Sultan Qaboos University that targeted all licensed Omani's undergraduate students. A total of 529 randomly selected students completed the self-reported questionnaire that included an assessment of driving behaviors (e.g., Driver Behaviour Questionnaire, DBQ) as well as the BIS/BAS measures. A total of 237 participants (44.8%) reported involvement in at least one crash since being licensed. Young drivers with lower BIS-Anxiety scores and higher BAS-Fun Seeking tendencies as well as male drivers were more likely to report driving violations. Statistically significant gender differences were observed on all BIS and BAS subscales (except for BAS-Fun) and the DBQ subscales, because males reported higher trait scores. Though personality traits were related to aberrant driving behaviors at the bivariate level, the constructs were not predictive of engaging in violations or errors. Furthermore, consistent with previous research, a supplementary multivariate logistic regression analysis revealed that only driving experience was predictive of crash involvement. The findings highlight that though personality traits influence self-reported driving styles (and differ between the genders), the relationship with crash involvement is not as clear. This article further outlines the key findings of the study in regards to understanding core psychological constructs that increase crash risk.

    This paper reports on the prevalence of texting while driving and other risky driving behaviors by age and gender in two large samples of youth aged 16-19 years in Ontario, Canada. In Study 1 (N=6133), we found that males reported more frequent texting while driving and speeding than females and, in terms of age, sixteen year olds reported frequent texting while driving than older participants. In Study 2 (N=4450), which was conducted two years later, males again reported more frequent texting while driving, however there was no difference in the rate of talking on the phone while driving among males and females. Participants also reported on experiences that led to a significant reduction in their texting while driving. The most common reasons were the perceived danger of texting while driving, laws and fines against texting while driving, and observing close-calls and accidents experienced by other people. The results of both studies suggest that driving-related risk-taking behaviors co-occur and that young passengers in vehicles, including 14 and 15 year olds, are bystanders to texting while driving. Finally, there was a substantial decline in the prevalence of texting while driving across the studies. In Study 1, 27% of participants reported "sometimes" to "almost always" texting while driving compared to 6% of participants in Study 2. Limitations and implications for public campaigns targeted youth distracted driving are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Researchers agree that a consistent definition for aggressive driving is lacking. Such definitional ambiguity in the literature impedes the accumulation of accurate and precise information, and prevents researchers from communicating clearly about findings and implications for future research directions. This dramatically slows progress in understanding the causes and maintenance factors of aggressive driving. This article critiques prevailing definitions of driver aggression and generates a definition that, if used consistently, can improve the utility of future research. Pertinent driving behaviors have been variably labeled in the literature as risky, aggressive, or road rage. The authors suggest that the term "road rage" be eliminated from research because it has been used inconsistently and has little probability of being clarified and applied consistently. Instead, driving behaviors that endanger or have the potential to endanger others should be considered as lying on a behavioral spectrum of dangerous driving. Three dimensions of dangerous driving are delineated: (a). intentional acts of aggression toward others, (b). negative emotions experienced while driving, and (c). risk-taking. The adoption of a standardized definition for aggressive driving should spark researchers to use more explicit operational definitions that are consistent with theoretical foundations. The use of consistent and unambiguous operational definitions will increase the precision of measurement in research and enhance authors' ability to communicate clearly about findings and conclusions. As this occurs over time, industry will reap benefits from more carefully conducted research. Such benefits may include the development of more valid and reliable means of selecting safe professional drivers, conducting accurate risk assessments, and creating preventative and remedial dangerous driving safety programs.

    Some evidence suggests that in recent years the prevalence of heavy drinking has increased among Russian adolescents. However, as yet, little is known about either heavy alcohol consumption or its relationship with other adolescent health risk behaviours in Russia. The aim of this study therefore was to investigate the association between binge drinking and health risk behaviours among adolescents in Russia. Data were drawn from the Social and Health Assessment (SAHA), a survey carried out in Arkhangelsk, Russia in 2003. Information was obtained from a representative sample of 2868 adolescents aged 13-17 regarding the prevalence and frequency of binge drinking (five or more drinks in a row in a couple of hours) and different forms of substance use, risky sexual behaviour and violent behaviour. Logistic regression analysis was used to examine the association between binge drinking and adolescent involvement in various health risk behaviours. Adolescent binge drinking was associated with the occurrence of every type of health risk behaviour - with the sole exception of non-condom use during last sex. In addition, there was a strong association between the number of days on which binge drinking occurred and the prevalence of many health risk behaviours. Binge drinking is associated with a variety of health risk behaviours among adolescents in Russia. Public health interventions such as reducing the affordability and accessibility of alcohol are now needed to reduce binge drinking and its harmful effects on adolescent well-being.

    The main aim of this research was to investigate the decision making process in risky situations. We studied how different types of feedback on risky driving behaviors modulate risk evaluation and risk-taking. For a set of risky traffic situations, participants had to make evaluative judgments (judge the situation as risky or not) and urgent decisions (brake or not). In Experiment 1, participants received feedback with and without negative emotional content when they made risky behaviors. In Experiment 2 we investigated the independent effects of feedback and negative emotional stimuli. The results showed three important findings: First, urgent decisions were faster [F(1, 92) = 6.76, p = .01] and more cautious [F(1, 92) = 17.16, p towards more cautious responses [F(1, 111) = 14.09, p emotional stimuli had an effect only when they were presented as feedback. The results of this research increase our understanding of the processes involved in risky driving behavior and suggest efficient ways to control risk taking through the use of feedback.

    Problem This paper summarizes the findings on novice teenage driving outcomes (e.g., crashes and risky driving behaviors) from the Naturalistic Teenage Driving Study. Method Survey and driving data from a data acquisition system (Global Positioning System, accelerometers, cameras) were collected from 42 newly-licensed teenage drivers and their parents during the first 18 months of teenage licensure; stress responsivity was also measured in teenagers. Result Overall teenage crash and near crash (CNC) rates declined over time, but were >4 times higher among teenagers than adults. Contributing factors to teenage CNC rates included secondary task engagement (e.g., distraction), kinematic risky driving, low stress responsivity, and risky social norms. Conclusion The data support the contention that the high novice teenage CNC risk is due both to inexperience and risky driving behavior, particularly kinematic risky driving and secondary task engagement. Practical Applications Graduated driver licensing policy and other prevention efforts should focus on kinematic risky driving, secondary task engagement, and risky social norms. PMID:26403899

    The burden of injuries due to drunk drivers has been estimated only indirectly. Indeed, alcohol is considered one of the most important contributing cause of car crash injuries and its effect on cognitive functions needs to be better elucidated. Aims of the study were i) to examine the effect of alcohol on attentive abilities involved while driving, and ii) to investigate whether Italian law limits for safe driving are sufficiently accurate to prevent risky behaviours and car crash risk while driving. We conducted a cross-over study at IRCCS Fondazione Santa Lucia Rehabilitation Hospital in Rome. Thirty-two healthy subjects were enrolled in this experiment. Participants were submitted to an attentive test battery assessing attention before taking Ethylic Alcohol (EA-) and after taking EA (EA+). In the EA+ condition subjects drank enough wine until the blood alcohol concentration, measured by means of Breath Analyzer, was equal to or higher than 0.5 g/l. Data analysis revealed that after alcohol assumption, tonic and phasic alertness, selective, divided attention and vigilance were significantly impaired when BAC level was at least 0.5 g/l. These data reveal that alcohol has a negative effect on attentive functions which are primarily involved in driving skills and that Italian law limits are adequate to prevent risky driving behaviour.

    Full Text Available Objective: The engagement and use of Information and Communications Technologies (ICTs has increased exponentially across societies worldwide with implications for social and psychological development in young people. In this context, the risk of negative sexual experience and victimisation online is known to have real world consequences for young people. This article seeks to: explore the nature of adolescent risk taking online behaviour from a group of young adults in different European countries; develop types of online risk profiles; explore the impact of help-seeking and to consider the potential real world harmful consequences. Method: A survey was administered across the United Kingdom, Ireland and Italy of 18 to 25 year olds in higher education, asking them about their online experiences between the ages of 12 and 16. Risky behaviour on and off-line, types of victimisation (on and offline and sexual solicitation requests online were analysed together with help-seeking behaviour. Results: Four profiles concerning adolescent risky behaviours were identified through cluster analysis. Each were distinguishable by a pattern of latent constructs linked to risk offline and online. Two were considered normative (adapted adolescents and inquisitive online and two high risk (risk-taking aggressive and sexually inquisitive online. Additionally, regression analysis demonstrated significant factors linked to predicting both likelihood of meeting an adult for sexual purposes, and help-seeking behaviour. Conclusions: The profiles developed are a useful tool for educators, police and health and social care practitioners in identifying adolescents at risk in order to undertake preventative work. Common help-seeking behaviour from peers could be used to effect interventions.

    Approximately 40% of all drowning deaths involve a motor vehicle. Regardless of its significance as a cause of flood-related mortality, there is continued prevalence of driving through flooded waterways in Australia and worldwide. We aimed to understand the motivational determinates of driving through flooded waterways in low and high-risk scenarios by utilizing an augmented theory of planned behaviour (TPB) with behavioural willingness as the outcome variable as well as the influence of additional predictors; namely perceived risk and past behaviour. Participants (n=174; Mage=27.43, SD=10.76) answered standard TPB-based questions in regards to attitudes, subjective norm, and perceived behavioural control (PBC), as well as additional variables of perceived risk (i.e., perceived susceptibility and perceived severity) and past behaviour. Support was found for the augmented TPB as attitude, subjective norm, and PBC predicted behavioural willingness. Support was also found for perceived severity in the high-risk but not the low-risk scenario. No support was found for perceived susceptibility. Past behaviour emerged as a significant predictor of willingness in the low and high-risk scenario. The findings provide support for an augmented TPB in understanding individuals' willingness to drive through flooded waterways, suggesting that a multi-strategy approach may be critical in attempts to reduce the incidence of such risky driving behaviour.

    Longitudinal patterns of maternal depressive symptoms have yet to be linked to risky behaviours, such as substance use or violence, in early adolescence, when such behaviours may be particularly detrimental. This study was carried out to do this. Using data from the UK's Millennium Cohort Study, it modelled the effect of trajectories of maternal depressive symptoms at child ages 3, 5, 7 and 11 years on antisocial behaviour and delinquency at age 11 years (N = 12,494). It also explored their role in predicting moral judgement and attitudes to alcohol at age 11, important predictors of delinquent or antisocial behaviour and alcohol use, respectively. Latent class analysis showed four longitudinal types of maternal depressive symptoms (chronically high, consistently low, moderate-accelerating and moderate-decelerating). Maternal symptom typology predicted antisocial behaviour in males and attitudes to alcohol in females, even after adjusting for youth's age and pubertal status and after correcting for confounding. Specifically, compared to males growing up with never-depressed mothers, those exposed to chronically high or accelerating maternal depressive symptoms were more likely to report engaging in loud and rowdy behaviour, alcohol use and bullying. Females exposed to chronically high maternal depressive symptoms were more likely than those growing up with never-depressed mothers to support the view that alcohol use is harmless. While causal conclusions cannot be drawn, these findings suggest that preventing or treating maternal depressive symptoms in childhood may be a useful approach to reducing future externalising and health-risk behaviours in offspring.

    Road traffic injuries are the largest cause of loss of disability-adjusted life years for men and women of all ages in the Kingdom of Saudi Arabia, but data on driving habits there are lacking. To inform policymakers on drivers' abilities and driving habits, we analyzed data from the Saudi Health Interview Survey 2013. We surveyed a representative sample of 5,235 Saudi males aged 15 years or older on wearing seat belts, exceeding speed limits, and using a handheld cell phone while driving. Male and female respondents were surveyed on wearing seat belts as passengers. Among Saudi males, 71.7% reported having had a driver's license, but more than 43% of unlicensed males drove a vehicle. Among drivers, 86.1% engaged in at least one risky behavior while driving. Older and unlicensed drivers were more likely to take risks while driving. This risk decreased among the more educated, current smokers, and those who are physically active. Up to 94.9% and 98.5% of respondents reported not wearing a seat belt in the front and the back passenger seats, respectively. The high burden of road traffic injuries in the Kingdom is not surprising given our findings. Our study calls for aggressive monitoring and enforcement of traffic laws. Awareness and proper education for drivers and their families should be developed jointly by the Ministries of Health, Interior Affairs, and Education and provided through their channels.

    The fishing communities are among population groups that are most at risk of HIV infection, with some studies putting the HIV prevalence at 5 to 10 times higher than in the general population. Alcohol consumption has been identified as one of the major drivers of the sexual risk behaviour in the fishing communities. This paper investigates the relationship between alcohol consumption patterns and risky behaviour in two fishing communities on Lake Victoria. Face-to-face interviews were conducted among 303 men and 172 women at the fish landing sites; categorised into fishermen, traders of fish or fish products and other merchandise, and service providers such as casual labourers and waitresses in bars and hotels, including 12 female sexual workers. Stratified random sampling methodology was used to select study units. Multivariable analysis was conducted to assess independent relationship between alcohol consumption and sexual risky behaviour. Measures of alcohol consumption included the alcohol use disorder test score (AUDIT), having gotten drunk in previous 30 days, drinking at least 2 times a week while measures for risky behaviour included engaging in transactional sex, inconsistent condom use, having sex with non-regular partner and having multiple sexual partners. The level of harmful use of alcohol in the two fishing communities was quite high as 62% of the male and 52% of the female drinkers had got drunk in previous 30 days. The level of risky sexual behaviour was equally high as 63% of the men and 59% of the women had unprotected sex at last sexual event. Of the 3 occupations fishermen had the highest levels of harmful use of alcohol and risky sexual behaviour followed by service providers judging from values of most indicators. The kind of alcohol consumption variables correlated with risky sexual behaviour variables, varied by occupation.

  11. Investigating Car Users’ Driving Behaviour through Speed Analysis

    Full Text Available Speed has been identified for a long time as a key risk factor in road traffic: inappropriate speeds contribute to a relevant part of traffic accidents. Many literature studies have focused on the relationship between speed and accident risk. Starting from this consideration this paper investigates traffic accident risk by analysing the travelling speeds recorded by real tests on the road. A survey was conducted to collect experimental speed values in a real context. A specific road segment, belonging to an Italian rural two-lane road, was repeatedly run by 27 drivers in order to collect the instantaneous speed values for each trajectory. Smartphone-equipped vehicles were used to record continuous speed data. The recorded data were used to calculate: the average speed, 50th and 85th percentile speed for each geometric element of the analysed road segment. The main result of the research is the classification of car users’ driving behaviour based on the speed values. By using the above mentioned ranges of speed, the classification provides three types of driving behaviour: safe, unsafe, and safe but potentially dangerous. It was found that only four drivers feature “safe” behaviour, driving in a safe manner on most of the road elements. However, the major part of drivers, even if they feature safe behaviour, could be dangerous for other drivers because they drive at very low speeds.

    We examined the potential moderating effects of appearance investment, body image disturbance, and situational body image dysphoria on the drive for muscularity attitude-behaviour relationship. Participants (339 British college men, M(AGE)=20.00 years, SD=2.59) completed drive for muscularity attitude and behaviour, appearance investment, body image disturbance, and situational body image dysphoria measures. Results indicated higher levels of appearance investment, body image disturbance, and situational body image dysphoria were associated with increases in the drive for muscularity attitude's relationship with physique-enhancing behavioural engagement. Results help extend recent research that has moved beyond identifying correlates to examining ways that groups of variables interact to predict drive for muscularity behavioural engagement and may contribute to theory development.

    Background Naturalistic driving studies, designed to objectively assess driving behavior and outcomes, are conducted by equipping vehicles with dedicated instrumentation (eg, accelerometers, gyroscopes, Global Positioning System, and cameras) that provide continuous recording of acceleration, location, videos, and still images for eventual retrieval and analyses. However, this research is limited by several factors: the cost of equipment installation; management and storage of the large amounts of data collected; and data reduction, coding, and analyses. Modern smartphone technology includes accelerometers built into phones, and the vast, global proliferation of smartphones could provide a possible low-cost alternative for assessing kinematic risky driving. Objective We evaluated an in-house developed iPhone app (gForce) for detecting elevated g-force events by comparing the iPhone linear acceleration measurements with corresponding acceleration measurements obtained with both a custom Android app and the in-vehicle miniDAS data acquisition system (DAS; Virginia Tech Transportation Institute). Methods The iPhone and Android devices were dashboard-mounted in a vehicle equipped with the DAS instrumentation. The experimental protocol consisted of driving maneuvers on a test track, such as cornering, braking, and turning that were performed at different acceleration levels (ie, mild, moderate, or hard). The iPhone gForce app recorded linear acceleration (ie, gravity-corrected). The Android app recorded gravity-corrected and uncorrected acceleration measurements, and the DAS device recorded gravity-uncorrected acceleration measurements. Lateral and longitudinal acceleration measures were compared. Results The correlation coefficients between the iPhone and DAS acceleration measurements were slightly lower compared to the correlation coefficients between the Android and DAS, possibly due to the gravity correction on the iPhone.

    Risky decision-making is characteristic of depression and of addictive disorders, including pathological gambling. However it is not clear whether a propensity to risky choices predisposes to depressive symptoms or whether the converse is the case. Here we tested the hypothesis that rats showing risky decision-making in a rat gambling task (rGT) would be more prone to depressive-like behaviour in the learned helplessness (LH) model. Results showed that baseline rGT choice behaviour did not predict escape deficits in the LH protocol. In contrast, exposure to the LH protocol resulted in a significant increase in risky rGT choices on retest. Unexpectedly, control rats subjected only to escapable stress in the LH protocol showed a subsequent decrease in riskier rGT choices. Further analyses indicated that the LH protocol affected primarily rats with high baseline levels of risky choices and that among these it had opposite effects in rats exposed to LH-inducing stress compared to rats exposed only to the escape trials. Together these findings suggest that while baseline risky decision making may not predict LH behaviour it interacts strongly with LH conditions in modulating subsequent decision-making behaviour. The suggested possibility that stress controllability may be a key factor should be further investigated.

    South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL) were searched for combinations of keywords including 'healthcare workers', 'risky sexual behaviour' and 'HIV and AIDS'. Articles from a range of countries met inclusion and exclusion criteria. Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

    Health-related problems and risky behaviours (substance use) are frequent in adolescents, may alter their physical and mental capabilities, and may thus generate school absenteeism, low academic performance, and school dropout ideation. This study assessed their associations and the contribution of socioeconomic factors among 1559 middle-school adolescents (mean age 13.5+1.3) from north-eastern France. They completed a questionnaire including socioeconomic characteristics, health-related problems (poor physical health, psychological health, social relationships, and living environment) assessed with the World Health Organization's quality of life measure (scoreschool absences during the present school year, last-trimester academic performance, and school dropout ideation. Data were analysed using logistic regression models. School absenteeism was frequent (12.6% of subjects for 8-14 days, and 6.0% for ≥15 days); 8.2% of subjects had low academic performance (average school-mark school dropout ideation. All school difficulties were strongly associated with all health-related problems (gender-age-school-level-adjusted odds ratios gasOR between 1.5 and 4.2), and with risky behaviours (gasOR between 1.4 and 14). Socioeconomic factors differently contributed to these associations (contribution reaching 77%). Policy makers, schools, physicians and parents should be more aware of the problems and help adolescents to reduce health-related problems and risky behaviours and to increase resilience.

    The purpose of this study was to examine the relationships among risky driving attitudes, self-perceptions as a risky driver, playing of "drive'em up" (which rewarded players for frequent traffic and other violations) and "circuit" racing video games as well as self-reported risky driving through a web-based survey of car and racing club members in relation to a socio-cognitive model of the effects of racing video game playing. An Internet questionnaire was developed and included: (1) self-perceptions as a risky driver scales (Driver Thrill Seeking and Competitive Attitude Toward Driving); (2) attitudes regarding street racing; (3) street racing video game playing, and (4) self-reported risky driving (Risk-Taking Driving Scale). A sequential logistic regression was performed entering age and driving exposure as control variables in the first block, self-perceptions as a risky driver in the second block, attitudes in the third block and playing "drive'em up" and "circuit" racing games in the last block to examine their effects on self-reported risk-taking driving. A total of 503 survey respondents were included in the analyses and only 20% reported any risk-taking driving. Higher score on the Competitive Attitude Toward Driving Scale, more positive attitudes toward street racing, and more frequent reported playing of "drive'em up" video games were associated with higher odds on the self-reported Risk-Taking Driving Scale. However, the Driver Thrill Seeking Scale and "circuit" video game playing failed to predict self-reported risk-taking driving. Self-perceptions as a risky driver, positive attitudes toward risky driving and "drive'em up" street-racing games, but not "circuit" racing games, are associated with increased risk-taking driving. These findings are congruent with experimental studies in which games that reward driving violations increased risk taking, suggesting that risk taking may be a function of type of street racing game played by affecting self

  20. From risky behaviour to sexy adventures: reconceptualising young people's online sexual activities.

    Western discourses about young people and sexuality centre around the concept of risk. Anxieties have been fuelled by the increasing popularity of social media and practices such as 'sexting' and watching 'sexually explicit' materials online. Research has shown however that such risk discourses mainly serve to moralise about, pathologise and police particular behaviours and children. In order to counter such paternalism, researchers advocated a reconceptualisation of youth not as passive victims, but as active agents who actively negotiate sexual experiences and discourses. In this paper, which is based on ethnographic fieldwork among young people in The Netherlands, I argue that we need a reconceptualisation not only of youth, but also of their sexual practices, especially their online sexual practices. Mobilising an interdisciplinary interaction between critical socio-cultural studies of risk, feminist theory and adventure studies, I propose to reconceptualise these practices as 'adventures' rather than 'risky behaviour'. This opens up possibilities for a more reasoned analysis that acknowledges: (1) the distinction between risks and outcomes of an activity; (2) the constructive potential of risk; and (3) the subjective, dynamic character of risk and pleasure.

    Full Text Available Risky outdoor play has been associated with promoting children’s health and development, but also with injury and death. Risky outdoor play has diminished over time, concurrent with increasing concerns regarding child safety and emphasis on injury prevention. We sought to conduct a systematic review to examine the relationship between risky outdoor play and health in children, in order to inform the debate regarding its benefits and harms. We identified and evaluated 21 relevant papers for quality using the GRADE framework. Included articles addressed the effect on health indicators and behaviours from three types of risky play, as well as risky play supportive environments. The systematic review revealed overall positive effects of risky outdoor play on a variety of health indicators and behaviours, most commonly physical activity, but also social health and behaviours, injuries, and aggression. The review indicated the need for additional “good quality” studies; however, we note that even in the face of the generally exclusionary systematic review process, our findings support the promotion of risky outdoor play for healthy child development. These positive results with the marked reduction in risky outdoor play opportunities in recent generations indicate the need to encourage action to support children’s risky outdoor play opportunities. Policy and practice precedents and recommendations for action are discussed.

    Novice motorists are at high crash risk during the first few months of driving. Risky behaviours such as speeding and driving while distracted are well-documented contributors to crash risk during this period. To reduce this public health burden, effective road safety interventions need to target the pre-driving period. We use the Theory of Planned Behaviour (TPB) to identify the pre-driver beliefs underlying intentions to drive over the speed limit (N=77), and while over the legal alcohol limit (N=72), talking on a hand-held mobile phone (N=77) and feeling very tired (N=68). The TPB explained between 41% and 69% of the variance in intentions to perform these behaviours. Attitudes were strong predictors of intentions for all behaviours. Subjective norms and perceived behavioural control were significant, though weaker, independent predictors of speeding and mobile phone use. Behavioural beliefs underlying these attitudes could be separated into those reflecting perceived disadvantages (e.g., speeding increases my risk of crash) and advantages (e.g., speeding gives me a thrill). Interventions that can make these beliefs safer in pre-drivers may reduce crash risk once independent driving has begun. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The workplace provides an important avenue to prevent HIV. To evaluate the effect of behavioral interventions for reducing HIV on high risk sexual behavior when delivered in an occupational setting. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and PsycINFO up until March 2011 and CINAHL, LILACS, DARE, OSH Update, and EPPI database up until October 2010. Randomised control trials (RCTs) in occupational settings or among workers at high risk for HIV that measured HIV, sexual transmitted diseases (STD), Voluntary Counseling and Testing (VCT), or risky sexual behaviour. Two reviewers independently selected studies for inclusion, extracted data and assessed risk of bias. We pooled studies that were similar. We found 8 RCTs with 11,164 participants but one study did not provide enough data. Studies compared VCT to no VCT and education to no intervention and to alternative education.VCT uptake increased to 51% when provided at the workplace compared to a voucher for VCT (RR=14.0 (95% CI 11.8 to16.7)). After VCT, self-reported STD decreased (RR = 0.10 (95% CI 0.01 to 0.73)) but HIV incidence (RR=1.4 (95% CI 0.7 to 2.7)) and unprotected sex (RR=0.71 (0.48 to 1.06)) did not decrease significantly. .Education reduced STDs (RR = 0.68 (95%CI 0.48 to 0.96)), unprotected sex (Standardised Mean Difference (SMD)= -0.17 (95% CI -0.29 to -0.05), sex with a commercial sex worker (RR = 0.88 (95% CI 0.81 to 0.96) but not multiple sexual partners (Mean Difference (MD) = -0.22 (95% CI -0.52 to 0.08) nor use of alcohol before sex (MD = -0.01 (95% CI of -0.11 to 0.08). Workplace interventions to prevent HIV are feasible. There is moderate quality evidence that VCT offered at the work site increases the uptake of testing. Even though this did no lower HIV-incidence, there was a decrease in self-reported sexual transmitted diseases and a decrease in risky sexual behaviour. There is low quality evidence that educational interventions decrease sexually

    While studies in demography and public health have acknowledged the role of ethnic differences, the influence of ethnicity on youth sexual behaviour in Nigeria has received little or no attention. It is important to know how cultural norms and gender roles, which vary by ethnicity, may promote or prevent risky behaviour. Such information could provide insights into previously undetected sexual behaviour in multi-ethnic situations. The Nigeria Demographic and Health Surveys (NDHS) for 2003, 2008 and 2013 were pooled to examine the relationship between ethnicity and youth sexual reproductive health, proxied by age at sexual debut, multiple sexual partners (MSP) and condom use at last sexual activity, among the 6304 females and 1549 males who reported being sexually active in the four weeks preceding the survey. Multivariate analysis using a Cox proportional hazard regression model was used to determine the risk factors for early sexual activity among young people (15-24). Logistic regression was used to predict condom use at last sexual activity and MSP. The median age at first sexual activity was 16 for females and 17 for males. 43% of male youths used condoms in their last sexual activity, compared to only 16% among females and a higher number of males (81%) had multiple sexual partners compared to females (35%). For females, elevated risks of first sex was higher among Hausa/Fulanis aged 15-19 and elevated risk of first sex was higher among Yoruba males. This study provides further evidence that in order to promote protective sexual behaviours among youth in Nigeria, social, cultural and gender-specific tactics should be put in place for the prevention of HIV and other STIs.

    Full Text Available The goal of the study was to investigate if the drivers behave in the same way when they are driving a motorcycle or a car. For this purpose, the Motorcycle Rider Behaviour Questionnaire and Driver Behaviour Questionnaire were conducted among the same drivers population. Items of questionnaires were used to develop a structural equation model with two factors, one for the motorcyclist’s behaviour, and the other for the car driver’s behaviour. Exploratory and confirmatory factor analyses were also applied in this study. Results revealed a certain difference in driving behaviour. The principal reason lies probably in mental consciousness that the risk-taking driving of a motorbike can result in much more catastrophic consequences than when driving a car. The drivers also pointed out this kind of thinking and the developed model has statistically confirmed the behavioural differences. The implications of these findings are also argued in relation to the validation of the appropriateness of the existing traffic regulations.

    Full Text Available In the present study, we investigated gender-related effects on road safety attitudesin 2,681 young drivers (1,458 males, 54.4%; aged 18-22 who filled out several scales assessing attitudes towards road safety issues, driving behaviour in specific hypothetical situations, accident risk perception, and concerns about such a risk. We focused only on young drivers to better understand the role of gender in road safety attitudes in a period of life in which risky behaviours are widespread for males and females. Indeed, there is still no agreement as to the nature of these gender differences. According to some authors, the effects of gender on being involved in a crash due to driving skills are either non-existent or largely explained by differences in alcohol consumption. In our study, we found gender differences in road safety attitudes (i.e., negative attitude toward traffic rules and risky driving; negative attitude towards drugs and alcohol and tolerance toward speeding and in driver behaviour (i.e., errors in inattentive driving and driving violations. This result is consistent in all drivers coming from nine different European countries. Our analyses yielded an important finding concerning risk perception. The results indicate that the level of risk perception during driving is the same for males and females. However, these two groups differ in the level of concern about this risk, with males being less concerned about the risk of a road accident. This suggests that the main difference between these two groups is not strictly related to judgment of the perceived risk probability but rather to the level of concern experienced about the consequences of the risk. This difference between risk perception and worry could explain differences in the frequency of car accidents in the two groups. The present findings may provide new insights for the development of gender-based prevention programs.

    Full Text Available Risky driving attitude terminology is used to explain behaviors, which directly increase accident risk, such as over speeding or violation to traffic rules while driving and attitudes related to traffic safety. This study is focused on driver factors in traffic accidents and was carried out in order to show risky drivers' attitudes tendency, especially. In this study, in order to develop a risky driver attitude model, factors explaining obedience to speed rules, caring about traffic accidents, risk taking tendency in traffic and violations of basic traffic rules were studied. For this reason with the assistance of structural equation models LISREL 8.54 was used to try to develop a model, and fitness of the model has been discussed considering various fitness criteria. On the other hand, analysis of variance was performed for factors measuring sex, education level, age and driving experience, in order to portrait risky drivers.

    Full Text Available Abstract Background Bicycle use entails high safety and health risks especially for adolescents. Most safety education programs aimed at adolescents focus on accident statistics and risk perceptions. This paper proposes the investigation of the social-cognitive correlates of risky cycling behaviors of adolescents prior to developing safety education programs. Method Secondary school students aged 13 to 18 years (n = 1446 filled out questionnaires regarding bicycle behavior, risky intentions, accident experience, and social-cognitive determinants as suggested by the theory of planned behavior. Results Regression analysis revealed that the proximal variables (i.e., self-efficacy, attitudes towards drunk driving, personal norm regarding safekeeping of self and others, and compared risk were able to predict 17% of the variance of risky behavior and 23% of the variance of risky intentions. The full model explained respectively 29% and 37% of the variance in risky behavior and risky intentions. Adolescents with positive attitudes towards risky behavior and low sense of responsibility report risky behavior, even when having been (close to an accident. Conclusions Adolescents realize whether they are risk takers or not. This implies that the focus of education programs should not be on risk perceptions, but on decreasing positive attitudes towards alcohol in traffic and increasing sense of responsibility instead. Cognitions regarding near accidents should be studied, the role of safe cycling self-efficacy is unclear.

    Thailand is among the first non-OECD countries to have introduced a form of Universal Health Coverage (UHC). This policy represents a natural experiment to evaluate the effects of public health insurance on health behaviours. In this paper, we examine the impact of Thailand's UHC programme on preventive activities, unhealthy or risky behaviours and health care consumption using data from the Thai Health and Welfare Survey. We use doubly robust estimators that combine propensity scores and linear regressions to estimate differences-in-differences (DD) and differences-in-DD models. Our results offer important insights. First, UHC increases individuals' likelihood of having an annual check-up, especially among women. Regarding health care consumption, we observe that UHC increases hospital admissions by over 2% and increases outpatient visits by 13%. However, there is no evidence that UHC leads to an increase in unhealthy behaviours or a reduction of preventive efforts. In other words, we find no evidence of ex ante moral hazard. Overall, these findings suggest positive health impacts among the Thai population covered by UHC.

    Risky health behaviours such as tobacco and alcohol abuse, physical inactivity and poor diet may play an important role in disease development. The aim of the present study was to assess the geographical distribution and socio-demographic determinants of risky health-related behaviours in 27 member states (MSs) of the European Union (EU). Data from the 2009 Eurobarometer survey (wave 72.3; n = 26 788) were analysed. Tobacco use, alcohol consumption, physical activity and fruit consumption were assessed through a self-reported questionnaire provided to participants from 27 EU MSs. Within the analyses, participants with three or more lifestyle risk factors were classified as individuals with co-occurrence of risk factors. Among respondents aged 15 or older, 28.2% had none of the aforementioned behavioural risk factors, whereas 9.9% had three or more lifestyle risk factors. Males [adjusted odds ratio (aOR) = 2.50; 95% confidence interval (95% CI): 2.17-2.88] and respondents of middle (aOR = 1.60; 95% CI: 1.36-1.89) or lower income (aOR = 2.63; 95% CI: 2.12-3.26) were more likely to report co-occurrence of behavioural risk factors, as well as respondents in Northern (aOR = 1.43; 95% CI: 1.14-1.78), Western (aOR = 1.28; 95% CI: 1.06-1.56) and Eastern Europe (aOR = 1.28; 95% CI: 1.06-1.55), when compared with Southern European respondents. The above analyses indicate significant geographical and social variation in the distribution of the co-occurrence of behavioural risk factors for disease development. © The Author 2015.

  18. Simulation Analysis on Driving Behavior during Traffic Sign Recognition

    Directory of Open Access Journals (Sweden)

    2011-05-01

    Full Text Available The traffic signs transfer trip information to drivers through vectors like words, graphs and numbers. Traffic sign with excessive information often makes the drivers have no time to read and understand, leading to risky driving. It is still a problem of how to clarify the relationship between traffic sign recognition and risky driving behavior. This paper presents a study that is reflective of such an effort. Twenty volunteers participated in the dynamic visual recognition experiment in driving simulator, and the data of several key indicators are obtained, including visual cognition time, vehicle acceleration and the offset distance from middle lane, etc. Correlations between each indicator above are discussed in terms of risky driving. Research findings directly show that drivers' behavior changes a lot during their traffic sign recognition.

    Little is known about the impact of cognitive impairments on driving in adults with ADHD. The present study compared the performance of adults with and without ADHD in a driving simulator on two different routes: an urban route which we hypothesised would exacerbate weak impulse control in ADHD and a motorway route, to challenge deficits in sustained attention. Adults with (n = 22, 16 males) and without (n = 21, 18 males) ADHD completed a simulated driving session while eye movement data were recorded simultaneously. Participants also completed the Manchester Driving Behaviour Questionnaire (DBQ) and the Conners Adult ADHD Rating Scale (CAARS). Measures of driving performance included average speed, proportion distance travelled over speed limit (speeding) and lane deviation. These variables and the eye movement measures (spread of fixations, mean fixation duration) were compared between groups and routes. Also, driving behaviours, including responses to programmed events, were categorised and the frequencies within categories were compared between groups. Finally, speech analysis was performed to compare emotional verbal expressions during driving between groups. ADHD participants reported significantly more Violations and Lapses on the DBQ than control participants and significantly more accidents. Average speed and speeding were also higher but did not interact with route type. ADHD participants showed poorer vehicle control, greater levels of frustration with other road users (including greater frequencies of negative comments) and a trend for less safe driving when changing lanes/overtaking on the motorway. These effects were predicted by hyperactive/impulsive CAARS scores. They were also more likely to cause a crash/near miss when an event occurred on the urban route. The results suggest that difficulty regulating and controlling impulsive behavior, reflected in speeding, frustration with other road users, less safety when changing lanes on the

    While some studies have found that those who perceive a behavior to be more risky are less likely to engage in it, others have found that those who engage in more risky behaviors see themselves as being more at-risk. Using an online questionnaire we investigated whether such conflicting findings may be due to the types of risk-questions employed in past studies. We assessed risk-perception using outcome-focused questions (e.g. the likelihood of being in an accident) and a behavior-focused question (the riskiness of speeding). Participants who reported engaging in more risky driving gave higher estimates of their chances of experiencing a negative outcome. However, those same participants gave lower estimates of the general riskiness of risky driving. Drivers may think about the risks of risky driving in different ways depending on the focus of the questions. Published by Elsevier Ltd.

    One of the prominent issues in contemporary research on young drivers deals with the mechanisms underlying parents' influences on their offspring's driving behavior. The present study combines two sets of data: the first gathered from in-vehicle data recorders tracking the driving of parents and their teenage sons, and the second derived from self-report questionnaires completed by the young drivers. The aim was to evaluate the contribution of parents' driving behavior, participation in a parent-targeted intervention, and the teen drivers' perception of the family climate for road safety, to the driving behavior of young drivers during solo driving. The data was collected over the course of 12 months, beginning with the licensure of the teen driver, and examined a sample of 166 families who were randomly assigned to one of three intervention groups (receiving different forms of feedback) or a control group (with no feedback). Findings indicate that young male drivers' risky driving events rate was positively associated with that of their parents. In addition, any type of intervention led to a lower rate of risky driving events among young drivers compared to the control group. Finally, a higher perception of parents as not committed to safety and lower perceived parental monitoring were related to a higher risky driving events rate among young drivers. The results highlight the need to consider a complex set of antecedents in parents' attitudes and behavior, as well as the family's safety atmosphere, in order to better understand young drivers' risky driving. The practical implications refer to the effective use of the family as a lever in the attempt to promote safety awareness among young drivers. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Background: South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV and acquired immune deficiency syndrome (AIDS globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Objectives: Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. Methods: This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL were searched for combinations of keywords including ‘healthcare workers’, ‘risky sexual behaviour’ and ‘HIV and AIDS’. Articles from a range of countries met inclusion and exclusion criteria. Results: Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. Conclusion: More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

    Assessing driving aptitude in dementia patients is critically important for both patient and public safety. However, there have been only a few reports on the driving behaviours and accident risk of patients with dementia, especially frontotemporal lobar degeneration (FTLD). Therefore, we compared the characteristics of driving behaviours in patients with FTLD and those with Alzheimer's disease (AD). The subjects were 28 FTLD and 67 AD patients who visited the Department of Psychiatry, Kochi Medical School Hospital. We conducted semi-structured interviews with their families and caregivers about traffic accident history and changes in patient driving behaviours after dementia onset and then compared the findings between the two groups. Overall changes in driving behaviours were reported in 89% (25/28) and 76% (51/67) of the FTLD and AD patients, respectively (P = 0.17). In the FTLD group, difficulty in judging inter-vehicle distances, ignoring road signs and traffic signals, and distraction were reported in 50% (14/28), 61% (17/28), and 50% (14/28) of patients, respectively, and 75% (21/28) patients had caused a traffic accident after dementia onset. The risk of causing an accident was higher in the FTLD group than in the AD group (odds ratio = 10.4, 95% confidence interval = 3.7-29.1). In addition, the mean duration between dementia onset and a traffic accident was 1.35 years in the FTLD group compared with 3.0 years in the AD group (P driving behaviours than those with AD, and the risk of causing a traffic accident may be higher in patients with FTLD from an early disease stage. © 2015 The Authors.

    Full Text Available Risky driving behavior is a major cause of traffic conflicts, which can develop into road traffic accidents, making the timely and accurate identification of such behavior essential to road safety. A platform was therefore established for analyzing the driving behavior of 20 professional drivers in field tests, in which overclose car following and lane departure were used as typical risky driving behaviors. Characterization parameters for identification were screened and used to determine threshold values and an appropriate time window for identification. A neural network-Bayesian filter identification model was established and data samples were selected to identify risky driving behavior and evaluate the identification efficiency of the model. The results obtained indicated a successful identification rate of 83.6% when the neural network model was solely used to identify risky driving behavior, but this could be increased to 92.46% once corrected by the Bayesian filter. This has important theoretical and practical significance in relation to evaluating the efficiency of existing driver assist systems, as well as the development of future intelligent driving systems.

    Recent examinations of road safety communications, including anti-speeding advertisements, have considered the differential effects of positive and negative emotional appeals on driver behaviour. However, empirical evaluations of anti-speeding messages have largely relied on measures of viewers' reported intentions to comply with speed limits and the self-reported driving behaviour of viewers post-exposure, which might not be indicative of the direct effects that these messages have on real-world driving behaviour. The current research constitutes a first empirical evaluation of different real-world anti-speeding advertisements, as measured by their effects on young drivers' speeding behaviour, using a driving simulator. Licensed drivers (N=116) aged 17-25 years completed driving measures prior to, immediately following, and 7-10days after viewing one of four social marketing advertisements. Results indicated that young drivers' average driving speeds were modestly reduced immediately after they viewed an anti-speeding advertisement that depicted social consequences for speeding and employed a positive emotional appeal when compared to an emotion-matched control advertisement; however, this effect was not found for the anti-speeding advertisement depicting a crash. Interestingly, the results based on reported intentions to reduce speeding predicted the opposite pattern of results. However, there was no evidence that the immediate changes to speeding were maintained 7-10days later, and prompts during Phase 2 did not appear to have an effect. The implications of these findings for road safety advertisements targeting young drivers are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Prior studies indicated higher collision rates among young novice drivers with peer passengers. This driving simulator study provided a test for a dual process theory of risky driving by examining social rewards (peer passengers) and cognitive control (inhibitory control). The analyses included age (17-18 yrs, n=30; 21-24 yrs, n=20). Risky, distracting, and protective effects were classified by underlying driver error mechanisms. In the first drive, participants drove alone. In the second, participants drove with a peer passenger. Red-light running (violation) was more prevalent in the presence of peer passengers, which provided initial support for a dual process theory of risk driving. In a subgroup with low inhibitory control, speeding (violation) was more prevalent in the presence of peer passengers. Reduced lane-keeping variability reflected distracting effects. Nevertheless, possible protective effects for amber-light running and hazard handling (cognition and decision-making) were found in the drive with peer passengers. Avenues for further research and possible implications for targets of future driver training programs are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Prior research has indicated that attention-deficit/hyperactivity disorder (ADHD) symptoms may be associated with an increased likelihood of engaging in risky sexual behaviour (RSB). However, research on this association among adolescents has been comparatively limited and mainly confined to North America. The aim of this study was to examine if inattention and hyperactivity/impulsivity symptoms were linked to RSB in a community cohort sample of Russian adolescents. The study was based on a group of 537 adolescents from Northern Russia. Information on inattention and hyperactivity/impulsivity as well as conduct problems was obtained through teacher ratings, while information on RSB (previous unprotected sex, number of sexual partners, sex while intoxicated and partner pregnancies), substance use, perception of risk, and parenting behaviour was based on students' self-reports. Binary logistic regression analysis was used to examine associations between the variables. Teacher-rated inattention symptoms predicted RSB, independently of co-morbid conduct problems, substance use, risk perception, and different parenting styles (parental warmth, involvement and control). In addition, male sex, binge drinking and a lower assessment of perceived risk were all significantly associated with RSB in an adjusted model. Neither teacher-rated hyperactivity/impulsivity symptoms nor conduct problems were linked to RSB in the full model. Deficits in planning and organizing behaviours, being easily distracted and forgetful seem to be of importance for RSB in Russian adolescents. This highlights the importance of discriminating between different ADHD symptoms in adolescence to prevent risk behaviours and their potentially detrimental outcomes on health and well-being.

    Full Text Available Abstract Background While alcohol-related health and social problems amongst youths are increasing internationally, both consumption and associated harms are particularly high in British youth. Youth drinking patterns, including bingeing, frequent drinking and drinking in public spaces, are associated with increased risks of acute (e.g. violence and long-term (e.g. alcohol-dependence health problems. Here we examine economic, behavioural and demographic factors that predict these risky drinking behaviours among 15–16 year old schoolchildren who consume alcohol. A cross-sectional survey was conducted among schoolchildren in North West England (n = 10,271 using an anonymous questionnaire delivered in school settings. Analysis utilised logistic regression to identify independent predictors of risky drinking behaviour. Results Of all respondents, 87.9% drank alcohol. Of drinkers, 38.0% usually binged when drinking, 24.4% were frequent drinkers and 49.8% drank in public spaces. Binge, frequent and public drinking were strongly related to expendable income and to individuals buying their own alcohol. Obtaining alcohol from friends, older siblings and adults outside shops were also predictors of risky drinking amongst drinkers. However, being bought alcohol by parents was associated with both lower bingeing and drinking in public places. Membership of youth groups/teams was in general protective despite some association with bingeing. Conclusion Although previous studies have examined predictors of risky drinking, our analyses of access to alcohol and youth income have highlighted eradicating underage alcohol sales and increased understanding of children's spending as key considerations in reducing risky alcohol use. Parental provision of alcohol to children in a family environment may also be important in establishing child-parent dialogues on alcohol and moderating youth consumption. However, this will require supporting parents to ensure they

    The goal of this study was to (a) investigate the association between nonprescription stimulant use (NPSU) and risky behaviors, including risky sex, driving, financial behaviors, and drug use and (b) collect preliminary evidence on mechanisms that may link NPSU to risky behaviors. A sample of 555 college students was collected between August 2010 and February 2012. Students completed several self-report measures assessing their drug use history, attention-deficit and hyperactivity symptoms, temperament, and risky behaviors beyond drug use. Those who reported more frequent NPSU were more likely to engage in high-risk behavior across all 4 domains studied. Further, effortful control abilities partially mediated the link between NPSU and risky behaviors. These results highlight the associated risks of frequent NPSU for college students as well as provide future directions for examining effortful control as a potentially important mechanism linking NPSU to other risky behaviors.

As safe and secure driving is a key strategy to reduce car injuries and offenses, the present research aimed to explore safe driving behaviours among taxi drivers based on the Health Belief Model (HBM). This study was conducted on 184 taxi drivers in Bandar Abbas who were selected based on a multiple stratified sampling method. Data were collected by a questionnaire comprised of a demographic information section along with the constructs of the HBM. Data were analysed by SPSS ver19 via a Pearson's correlation coefficient and multiple regressions. The mean age of the participants was 45.1 years (SD = 11.1). They all had, on average, 10.3 (SD = 7/5) years of taxi driving experience. Among the HBM components, cues to action and perceived benefits were shown to be positively correlated with safe driving behaviours, while perceived barriers were negatively correlated. Cues to action, perceived barriers and perceived benefits were shown to be the strongest predictors of a safe drivers' behaviour. Based on the results of this study in designing health promotion programmes to improve safe driving behaviours among taxi drivers, cues to action, perceived benefits and perceived barriers are important. Therefore, advertising, the design of information campaigns, emphasis on the benefits of safe driving behaviours and modification barriers are recommended.

    Full Text Available The personality traits that mediate risky driving and accidents among university students drivers were investigated. Study 1 (N=132 tested for the relation between risky behaviors and personality (16PF-5 second order dimensions. Three factors were extracted concerning risky driving: driving errors of commission, distraction, and driving errors of omission. Individuals with low self-control and high levels of anxiety were more prone to commit distractive behavior and driving errors of omission. Low self-control and high independence levels were associated with driving errors of commission. In study 2 (N=540, we tested if the number of road accidents for which an individual has been responsible was related to risky driving behavior. Drivers who committed more accidents presented higher scores in three new risky driving factors obtained: reckless driving, impaired concentration and division of attention.

    The aim of the study was to characterize the predictive value of socio-economic data, alcohol consumption measures, smoking, platelet monoamine oxidase (MAO) activity, traffic behaviour habits and impulsivity measures for actual drunk driving. Data were collected from 203 male drunk driving offenders and 211 control subjects using self-reported questionnaires, and blood samples were obtained from the two groups. We identified the combination of variables, which predicted correctly, approximately 80% of the subjects' belonging to the drunk driving and control groups. Significant independent discriminators in the final model were, among the health-behaviour measures, alcohol-related problems, frequency of using alcohol, the amount of alcohol consumed and smoking. Predictive traffic behaviour measures were seat belt use and paying for parking. Among the impulsivity measures, dysfunctional impulsivity was the best predictor; platelet MAO activity and age also had an independent predictive value. Our results support the notion that drunk driving is the result of a combination of various behavioural, biological and personality-related risk factors.

    The purpose of this study was to investigate the relationship between driving anger and aberrant driving behaviours. An internet-based questionnaire survey was administered to a sample of Chinese drivers, with driving anger measured by a 14-item short Driving Anger Scale (DAS) and the aberrant driving behaviours measured by a 23-item Driver Behaviour Questionnaire (DBQ). The results of Confirmatory Factor Analysis demonstrated that the three-factor model (hostile gesture, arrival-blocking and safety-blocking) of the DAS fitted the driving anger data well. The Exploratory Factor Analysis on DBQ data differentiated four types of aberrant driving, viz. emotional violation, error, deliberate violation and maintaining progress violation. For the anger-aberration relation, it was found that only "arrival-blocking" anger was a significant positive predictor for all four types of aberrant driving behaviours. The "safety-blocking" anger revealed a negative impact on deliberate violations, a finding different from previously established positive anger-aberration relation. These results suggest that drivers with different patterns of driving anger would show different behavioural tendencies and as a result intervention strategies may be differentially effective for drivers of different profiles.

    HIV is most prevalent among men who have sex with men (MSM), and although most MSM use condoms consistently during casual sex, some take risks. To better understand the psychology of those risky decisions, we examined neural correlates of playing a virtual sexual 'hook up' game in an functional magnetic resonance imaging scanner in MSM who had, in the past 90 days, been sexually risky (N = 76) or safe (N = 31). We found that during potentially risky sexual choices, previously risky MSM had more right insula activity than previously safe MSM. Real-life sexual risk was related to trait positive and negative urgency. Insula activity that differentiated risky and safe MSM was related to trait positive and negative urgency. Future work should further examine if, and to what extent, insula activation during safe sex negotiation drives MSM's rash risky sexual decision-making. © The Author (2017).

    Attitudes and individual difference variables of car and racing enthusiasts regarding high-risk behaviors of street racing and stunt driving have recently been investigated. Positive attitudes toward high-risk driving, personality variables such as driver thrill seeking, and other self-reported risky driving acts were associated with these behaviors. However, probable relationships among high-risk driving tendencies, everyday driving behaviors, and negative road safety outcomes have remained largely unexamined. This study aimed to investigate the associations among car and racing enthusiasts' high-risk driving attitudes, self-reported everyday driving violations (i.e., ordinary and aggressive violations), and self-reported negative outcomes (i.e., collisions and driving offense citations). A web-based survey was conducted with members and visitors of car club and racing websites in Ontario, Canada. Data were obtained from 366 participants. The questionnaire included 4 attitude measures-(1) attitudes toward new penalties for Ontario's Street Racers, Stunt and Aggressive Drivers Legislation; (2) attitudes toward new offenses of stunt driving under the same legislation; (3) general attitudes toward street racing and stunt driving; (4) comparison of street racing with other risky driving behaviors-self-reported driving violations (i.e., ordinary and aggressive violations); self-reported collisions and offense citations; and background and driving questions (e.g., age, driving frequency). Results revealed that attitudes toward stunt driving offenses negatively and general attitudes toward street racing and stunt driving positively predicted ordinary violations, which, in turn, predicted offense citations. Moreover, general attitudes toward street racing and stunt driving positively predicted aggressive violations, which, in turn, predicted offense citations. The findings indicate that positive high-risk driving attitudes may be transferring to driving violations in

    The public's negative attitudes towards household insects drive tolerance for these insects and their control. Tolerance levels are important in integrated pest management (IPM), as are pest knowledge and information. The risk information seeking and processing (RISP) model describes the relationships between personal factors and information-seeking behaviour. We combined IPM and RISP to determine important relationships between factors driving insect tolerance levels and information-seeking behaviour through an online survey and tested whether this model is valid and generally applicable. Relationships between variables from both IPM and RISP models were tested for seven insect species. Tolerance levels were measured with two factors: willingness to pay for pest control and whether insects are tolerated. Willingness to pay for control was positively affected by age, experience, risk perception, insect characteristics, and negative emotions and affected behavioural intention, by influencing information sufficiency and information-seeking behaviour. Tolerability was influenced by perception of insect characteristics and determines whether control measures are taken. It was possible to combine the RISP and IPM models. Relevant driving factors were a person's age, experience, risk perception, negative affective responses, tolerance levels, relevant channel beliefs about online forums, information sufficiency and information-seeking behaviour. There was, however, variation in important factors between different insects. © 2017 The Authors.

    Few studies have investigated the role of disenfranchisement and denial of agency in women's sexual health. To address this, a cross-sectional study of disenfranchisement, control (general and reproductive control) and health was conducted in Ireland, where abortion is severely restricted. Multiple mediation models ( N = 513 women) indicated that general but not reproductive control mediates the association between disenfranchisement and psychological well-being. Additionally, serial mediation shows disenfranchisement is associated with lower sense of control, which is linked to poorer well-being and risky sexual behaviour. Disenfranchisement arising from socio-political contexts may have important implications for women's sexual health.

    Risky decision making and disadvantageous choices constitute core characteristics of patients with attention-deficit/hyperactivity disorder (ADHD). Consequences include negative psychosocial and health-related outcomes. However, risky decision making and its interrelations with emotional states in ADHD are poorly understood. Therefore, the authors investigated risky decision making without and after boredom induction in adults with and without ADHD. In study 1, ADHD patients (n = 15) and age/education matched controls (CG; n = 16) were compared on the Game of Dice Task (GDT), an established task measuring decision making in unambiguous situations. In study 2, ADHD patients (n = 14) and CG (n = 13) underwent boredom induction prior to the GDT. In study 1, ADHD patients selected the disadvantageous alternatives significantly more often than CG. In study 2, no significant group differences were found due to an increase in risky decision making in CG following the boredom induction. Even if severity of depression did not affect our results, it may be necessary to compare GDT responses in ADHD patients with and without current depression. Risk as a motor of disadvantageous decision making needs to be taken into account in therapeutic contexts as a maintenance factor of dysfunctional behaviour. The findings of study 2 are in line with postulated alterations of emotional state adjustment in ADHD. The link between decisions making and emotional regulation in ADHD needs further attention in research. Copyright © 2012 Elsevier Ltd. All rights reserved.

    While in-vehicle eco-driving support systems have the potential to reduce greenhouse gas emissions and save fuel, they may also distract drivers, especially if the system makes use of a visual interface. The objective of this study is to investigate the visual behaviour of drivers interacting with such a system, implemented on a five-inch screen mounted above the middle console. Ten drivers participated in a real-world, on-road driving study where they drove a route nine times (2 pre-baseline drives, 5 treatment drives, 2 post-baseline drives). The route was 96 km long and consisted of rural roads, urban roads and a dual-lane motorway. The results show that drivers look at the system for 5-8% of the time, depending on road type, with a glance duration of about 0.6 s, and with 0.05% long glances (>2s) per kilometre. These figures are comparable to what was found for glances to the speedometer in this study. Glance behaviour away from the windscreen is slightly increased in treatment as compared to pre- and post-baseline, mirror glances decreased in treatment and post-baseline compared to pre-baseline, and speedometer glances increased compared to pre-baseline. The eco-driving support system provided continuous information interspersed with additional advice pop-ups (announced by a beep) and feedback pop-ups (no auditory cue). About 20% of sound initiated advice pop-ups were disregarded, and the remaining cases were usually looked at within the first two seconds. About 40% of the feedback pop-ups were disregarded. The amount of glances to the system immediately before the onset of a pop-up was clearly higher for feedback than for advice. All in all, the eco-driving support system under investigation is not likely to have a strong negative impact on glance behaviour. However, there is room for improvements. We recommend that eco-driving information is integrated with the speedometer, that optional activation of sound alerts for intermittent information is made

    Serious crashes are more likely when teenage drivers have teenage passengers. One likely source of this increased risk is social influences on driving performance. This driving simulator study experimentally tested the effects of peer influence (i.e., risk-accepting compared to risk-averse peer norms reinforced by pressure) on the driving risk behavior (i.e., risky driving behavior and inattention to hazards) of male teenagers. It was hypothesized that peer presence would result in greater driving risk behavior (i.e., increased driving risk and reduced latent hazard anticipation), and that the effect would be greater when the peer was risk-accepting. Fifty-three 16- and 17-year-old male participants holding a provisional U.S., State of Michigan driver license were randomized to either a risk-accepting or risk-averse condition. Each participant operated a driving simulator while alone and separately with a confederate peer passenger. The simulator world included scenarios designed to elicit variation in driving risk behavior with a teen passenger present in the vehicle. Significant interactions of passenger presence (passenger present vs. alone) by risk condition (risk-accepting vs. risk-averse) were observed for variables measuring: failure to stop at yellow light intersections (Incident Rate Ratio (IRR)=2.16; 95% Confidence Interval [95CI]=1.06, 4.43); higher probability of overtaking (IRR=10.17; 95CI=1.43, 73.35); shorter left turn latency (IRR=0.43; 95CI=0.31,0.60); and, failure to stop at an intersection with an occluded stop sign (IRR=7.90; 95CI=2.06,30.35). In all cases, greater risky driving by participants was more likely with a risk-accepting passenger versus a risk-averse passenger present and a risk-accepting passenger present versus driving alone. Exposure of male teenagers to a risk-accepting confederate peer passenger who applied peer influence increased simulated risky driving behavior compared with exposure to a risk-averse confederate peer

    This study examined the association of risky dieting amongst adolescent girls with depressed mood, family conflict, and parent-child emotional closeness. Grade 6 and 8 females (aged 11-14years, N=4031) were recruited from 231 schools in 30 communities, across three Australian States (Queensland, Victoria, and Western Australia). Key measures were based on the Adolescent Dieting Scale, Short Mood and Feelings Questionnaire, and widely used short measures of family relationship quality. Controls included age, early pubertal onset, and socioeconomic status. Risky dieting was significantly related to family conflict and depressed mood, depressed mood mediated the association of family conflict and risky dieting, and these associations remained significant with controls in the model. Family conflict and adolescent depressed mood are associated with risky dieting. Prevention programs may benefit from a broadening of behavioural targets to include depressed mood and family problems. Copyright © 2016 Elsevier Ltd. All rights reserved.

  7. Risky business: rhesus monkeys exhibit persistent preferences for risky options.

    Rhesus monkeys have been shown to prefer risky over safe options in experiential decision-making tasks. These findings might be due, however, to specific contextual factors, such as small amounts of fluid reward and minimal costs for risk-taking. To better understand the factors affecting decision-making under risk in rhesus monkeys, we tested multiple factors designed to increase the stakes including larger reward amounts, distinct food items rather than fluid reward, a smaller number of trials per session, and risky options with greater variation that also included non-rewarded outcomes. We found a consistent preference for risky options, except when the expected value of the safe option was greater than the risky option. Thus, with equivalent mean utilities between the safe and risky options, rhesus monkeys appear to have a robust preference for the risky options in a broad range of circumstances, akin to the preferences found in human children and some adults in similar tasks. One account for this result is that monkeys make their choices based on the salience of the largest payoff, without integrating likelihood and value across trials. A related idea is that they fail to override an impulsive tendency to select the option with the potential to obtain the highest possible outcome. Our results rule out strict versions of both accounts and contribute to an understanding of the diversity of risky decision-making among primates.

    Full Text Available Cocaine use disorder is associated with maladaptive decision-making behaviour, which strongly contributes to the harmful consequences of chronic drug use. Prior research has shown that cocaine users exhibit impaired neuropsychological test performances, particularly with regard to attention, learning, and memory but also in executive functions such as decision-making and impulse control. However, to what extent cocaine users show impaired decision-making under risk without feedback has not yet been investigated systematically. Therefore, to examine risk-taking behaviour, 31 chronic cocaine users and 26 stimulant-naïve healthy controls, who were part of the Zurich Cocaine Cognition Study, performed the Randomized Lottery Task (RALT with winning lotteries consisting of an uncertain and a certain prospect. Results revealed that risky decisions were associated with male sex, increased cocaine use in the past year, higher cocaine concentrations in the hair, and younger age. In addition, higher levels of cocaine in the hair and cumulative lifetime consumption were associated with risky decisions, whereas potentially confounding factors including cognition and psychiatric symptoms had no significant effect. Taken together, our results indicate that cocaine users who increased their consumption over a period of one year show deficits in the processing of risky information accompanied with increased risk-taking. Future research should analyse whether risky decisions could potentially serve as a prognostic marker for cocaine use disorder.

    Early smoking is considered an indicator for risky behaviour in adolescents. Although social indicators predicting adolescent smoking are known, biological indicators have not been defined. This study aimed to establish whether salivary testosterone could be used as a "predictive biomarker" for smoking-associated peer pressure. Saliva samples were collected from Bruneian adolescents (aged 13-17 years) by the passive drool method. Salivary testosterone concentration was determined by enzyme-linked immunosorbent assay. Salivary testosterone concentration and smoking-associated peer pressure indicators were compared between adolescent males and females and statistical significance was determined by an independent samples t-test. A significant positive relationship between smoking-associated peer pressure and salivary testosterone levels in adolescents was found. However, this relationship was not significant when males and females were considered separately. Our data suggest that students who have tried cigarette smoking and have friends who are cigarette smokers have higher salivary testosterone levels.

    A large, district-wide, home-based HIV counselling and testing (HBHCT) programme was implemented in Bushenyi district of Uganda from 2004 to 2007. This programme provided free HBHCT services to all consenting adults of Bushenyi district and had a very high uptake and acceptability. We measured population-level changes in knowledge of HIV status, stigma and HIV-risk behaviours before and after HBHCT to assess whether widespread HBHCT had an effect on trends of risky sexual behaviours and on stigma and discrimination towards HIV. Serial cross-sectional surveys were carried out before and after the implementation of HBHCT programme in Bushenyi district of Uganda. A total of 1402 randomly selected adults (18 to 49 years) were interviewed in the baseline survey. After the implementation, a different set of randomly selected 1562 adults was interviewed using the same questionnaire. Data was collected on socio-demographic characteristics, sexual behaviour, whether respondents had ever tested for HIV and stigma and discrimination towards HIV/AIDS. The proportion of people who had ever tested for HIV increased from 18.6% to 62% (pHIV test result with a sexual partner increased from 41% to 57% (pHIV services especially in areas where access to HCT is low.

    Kuwait mandated seat-belt use by drivers in 1976 and by front seat passengers in 1994. The study objectives were to identify and estimate current factors associated with seat-belt use and levels of potentially unsafe driving behaviours in Kuwait. In 2010, 741 adults were surveyed regarding driving habits and history. Only 41.6% of drivers reported always using a seat belt. Front seat passenger belt use was more common (30.5%) than rear seat belt use (6.5%). Distracted driving behaviours were common, including mobile phone use ('always' or 'almost always': 51.1%) and texting/SMS (32.4%). Logistic regression indicated that drivers who were young (18-19 years), male, Kuwaiti nationals or non-Kuwaiti Arabs, drove over the speed limit, had traffic violation tickets or >1 car crashes in the last year, were less likely to use seat belts. Targeted initiatives to increase public awareness and to enforce car-safety legislation, including use of seat belts, are necessary to decrease the health burden of car crashes in Kuwait.

    The developed world faces major socioeconomic and medical challenges associated with motor vehicle accidents caused by risky driving. Functional magnetic resonance imaging (fMRI) of individuals using virtual reality driving simulators may provide an important research tool to assess driving safety, based on brain activity and behavior. A fMRI-compatible driving simulator was developed and evaluated in the context of straight driving, turning, and stopping in 16 young healthy adults. Robust maps of brain activity were obtained, including activation of the primary motor cortex, cerebellum, visual cortex, and parietal lobe, with limited head motion (driving is a feasible undertaking.

    ADHD has been associated with various forms of risky real life decision making, for example risky driving, unsafe sex and substance abuse. However, results from laboratory studies on decision making deficits in ADHD have been inconsistent, probably because of between study differences. We therefore performed a meta-regression analysis in which 37 studies (n ADHD=1175; n Control=1222) were included, containing 52 effect sizes. The overall analysis yielded a small to medium effect size (standardized mean difference=.36, pdecision making than control groups. There was a trend for a moderating influence of co-morbid Disruptive Behavior Disorders (DBD): studies including more participants with co-morbid DBD had larger effect sizes. No moderating influence of co-morbid internalizing disorders, age or task explicitness was found. These results indicate that ADHD is related to increased risky decision making in laboratory settings, which tended to be more pronounced if ADHD is accompanied by DBD. We therefore argue that risky decision making should have a more prominent role in research on the neuropsychological and -biological mechanisms of ADHD, which can be useful in ADHD assessment and intervention.

    Although most motorised countries have experienced massive improvements in road safety over the last decades, human behaviour and differences in accident risk across sub-groups of drivers remains a key issue in the area of road safety. The identification of risk groups requires the identification of reliable predictors of safe or unsafe driving behaviour. Given this background, the aim of this study was to test whether driver sub-groups identified based on self-reported driving behaviour and skill differed in registered traffic law offences and accidents, and whether group membership was predictive of having traffic law offences. Sub-groups of drivers were identified based on the Driver Behaviour Questionnaire (DBQ) and the Driver Skill Inventory (DSI), while traffic offences and accidents were register-based (Statistics Denmark). The participants (N=3683) were aged 18-84 years and randomly selected from the Danish Driving License Register. Results show that the driver sub-groups differed significantly in registered traffic offences but not in registered accidents. In a logistic regression analysis, the sub-group "Violating unsafe drivers" was found predictive of having a traffic offence, even when socio-demographic variables and exposure were controlled for. The most important predictive factor, however, was having a criminal record for non-traffic offences, while gender, living without a partner, and being self-employed also had a significant effect. The study confirms the use of the DBQ and DSI as suitable instruments for predicting traffic offences while also confirming previous results on accumulation of problematic behaviours across life contexts. The finding that driver sub-groups did not differ in registered accidents supports the recent research activities in finding and modelling surrogate safety measures. Copyright © 2016 Elsevier Ltd.

    The aim of this research was to explore unwanted sexual behaviour amongs young people. Sexual aggression was operationalized at three levels: ‘‘verbal’’, ‘‘non-verbal/intimidating’’ and ‘‘physically violent’’. A total of 1,700 Dutch adolescents completed a questionnaire that included six clusters of possible determinants of unwanted sexual behaviour: background characteristics, personality characteristics, family environment, school environment, friends and deviant behaviour and sexuality and...

    Previous research on older drivers has indicated connections between self-rated driving ability, confidence in their own driving, driving-related stress, and self-regulatory behaviour. However, more systematic associations between older drivers' perceptions on their own driving and self......-regulation or driver stress and self-regulation behaviour, and possible gender differences in these, have not been obtained in previous studies. The aim of the present study was to gain a better understanding of older drivers' self-regulatory driving and the motivators behind this behaviour, by placing this behaviour...... and avoidance than situations related to infrastructure, and women were more likely to report discomfort and avoidance of driving situations. The results suggest that older drivers generally show good self-judgement of changes in their driving skills and acknowledge the different types of skills comprised...

    Racing games have emerged as top-selling products in the video and computer game industry. The effect of playing racing games on the inclination of gamers to take risks has been investigated. Two experiments were conducted. In experiment 1, the impact of personality traits on the effects of playing racing games on risk-taking inclination was examined. The Vienna Test System, which includes the Eysenck Personality Profile Test and the Vienna Risk-Taking Test, was used to measure risk-taking inclination and risk-taking while driving. Experiment 2 was designed and conducted to analyse the effects of different intensity levels of car racing games on risk-taking inclination, and to study the relationship between physiological data and risk-taking inclination. Physiological data on skin conductance, heart rate and blood pressure were measured with the NeuroDyne System. Participants playing a racing game were more inclined to take risks in critical road traffic situations than those playing a neutral game. The adventurousness dimension of the Eysenck Personality Profile Test correlated significantly positively with risk-taking inclination. More importantly, the effect of the intensity level of a racing game on risk-taking inclination was significant. The higher the intensity level of the racing game, the higher the risk-taking inclination while driving. The effect of intensity level of the racing game on skin conductance was significantly positive. Skin conductance correlated significantly positively with risk-taking inclination. The effect of playing racing games on risk-taking inclination is linked to personality and physiological data. Some recommendations are proposed as a result of this study for racing game management.

    Individual differences in morningness-eveningness preference may influence susceptibility and response to sleepiness. These differences could influence driving performance, but the influence of morningness-eveningness preference on driving behavior and accident risk has not been comprehensively studied. As morningness-eveningness preference is associated with personality characteristics, we also investigated how the interaction between morningness-eveningness preference and personality may be related to dangerous driving behaviors. Two hundred and ninety five drivers completed the reduced Morningness-Eveningness Questionnaire, the Dula Dangerous Driving Index, and personality scales for agreeableness, conscientiousness and neuroticism, and reported demographic information (gender, age, level of education, driving years and annual average driving mileage) and self-reported traffic violations (accidents, penalty points and fines). The results showed that more Risky Driving, Aggressive Driving, Negative Cognitive/Emotional Driving and Drunk Driving, as measured by the Dula Dangerous Driving Index, were all significantly correlated with more eveningness, corresponding to lower scores on the reduced Morningness-Eveningness Questionnaire. Moreover, eveningness was correlated with self-reported traffic accidents, penalty points and fines. Furthermore, a moderation effect was found: eveningness was more strongly associated with risky driving and negative emotional driving in those who scored high for trait agreeableness.

    2018-04-03

    Although the taxi industry is playing an important role in Chinese everyday life, little attention has been posed towards occupational health issues concerning the taxi drivers' working conditions, driving behaviour and road safety. A cross-sectional survey was administered to 1021 taxi drivers from 21 companies in four Chinese cities and collected information about (i) sociodemographic characteristics, (ii) working conditions, (iii) frequency of daily aberrant driving behaviour, and (iv) involvement in property-damage-only (PDO) and personal injury (PI) crashes over the past two years. A hybrid bivariate model of crash involvement was specified: (i) the hybrid part concerned a latent variable model capturing unobserved traits of the taxi drivers; (ii) the bivariate part modelled jointly both types of crashes while capturing unobserved correlation between error terms. The survey answers paint a gloomy picture in terms of workload, as taxi drivers reported averages of 9.4 working hours per day and 6.7 working days per week that amount on average to about 63.0 working hours per week. Moreover, the estimates of the hybrid bivariate model reveal that increasing levels of fatigue, reckless behaviour and aggressive behaviour are positively related to a higher propensity of crash involvement. Lastly, the heavy workload is also positively correlated with the higher propensity of crashing, not only directly as a predictor of crash involvement, but also indirectly as a covariate of fatigue and aberrant driving behaviour. The findings from this study provide insights into potential strategies for preventive education and taxi industry management to improve the working conditions and hence reduce fatigue and road risk for the taxi drivers.

    2014-01-01

    Motor vehicle crashes are the leading source of morbidity and mortality in adolescents in the United States and the developed world. Inadequate allocation of attention to the driving task and to driving hazards are important sources of adolescent crashes. We review major explanations for these attention failures with particular focus on the roles that brain immaturity and lack of driving experience play in causing attention problems. The review suggests that the potential for overcoming inexperience and immaturity with training to improve attention to both the driving task and hazards is substantial. Nevertheless, there are large individual differences in both attentional abilities and risky driving tendencies that pose challenges to novice driver policies. Research that can provide evidence-based direction for such policies is urgently needed. PMID:24759442

    Impulse control disorders (ICDs) in Parkinson's disease (PD) are considered dopaminergic treatment side effects. Cognitive and affective factors may increase the risk of ICD in PD. The aim is to investigate risky decision-making and associated cognitive processes in PD patients with ICDs within a four-stage conceptual framework. Relationship between ICDs and affective factors was explored. Thirteen PD patients with ICD (ICD+), 12 PD patients without ICD (ICD-), and 17 healthy controls were recruited. Overall risky decision-making and negative feedback effect were examined with the Balloon Analogue Risk Task (BART). A cognitive battery dissected decision-making processes according to the four-stage conceptual framework. Affective and motivational factors were measured. ANOVA showed no effect of group on overall risky decision-making. However, there was a group × feedback interaction [F (2, 39) = 3.31, p = 0.047]. ICD+, unlike ICD- and healthy controls, failed to reduce risky behaviour following negative feedback. A main effect of group was found for anxiety and depression [F(2, 38) = 8.31, p = 0.001], with higher symptoms in ICD+ vs. healthy controls. Groups did not differ in cognitive outcomes or affective and motivational metrics. ICD+ may show relatively preserved cognitive function, but reduced sensitivity to negative feedback during risky decision-making and higher symptoms of depression and anxiety.

    Young drivers are overrepresented in collisions resulting in fatalities. It is not uncommon for young drivers to socially binge drink and decide to drive a vehicle a few hours after consumption. To better understand the risks that may be associated with this behaviour, the present study has examined the effects of a social drinking bout followed by a simulated drive in undergraduate students on the descending limb of their BAC (blood alcohol concentration) curve. Two groups of eight undergraduate students (n = 16) took part in this study. Participants in the alcohol group were assessed before drinking, then at moderate and low BAC as well as 24 hours post-acute consumption. This group consumed an average of 5.3 ± 1.4 (mean ± SD) drinks in an hour in a social context and were then submitted to a driving and a predicted crash risk assessment. The control group was assessed at the same time points without alcohol intake or social context.; at 8 a.m., noon, 3 p.m. and 8 a.m. the next morning. These multiple time points were used to measure any potential learning effects from the assessment tools (i.e. driving simulator and useful field of view test (UFOV)). Diminished driving performance at moderate BAC was observed with no increases in predicted crash risk. Moderate correlations between driving variables were observed. No association exists between driving variables and UFOV variables. The control group improved measures of selective attention after the third assessment. No learning effect was observed from multiple sessions with the driving simulator. Our results show that a moderate BAC, although legal, increases the risky behaviour. Effects of alcohol expectancy could have been displayed by the experimental group. UFOV measures and predicted crash risk categories were not sensitive enough to predict crash risk for young drivers, even when intoxicated.

  15. A qualitative exploration of driving stress and driving discourtesy.

    Driving courtesy, and conversely driving discourtesy, recently has been of great interest in the public domain. In addition, there has been increasing recognition of the negative impact of stress upon the individual's health and wellbeing, with a plethora of interventions aimed at minimising stress more generally. The research literature regarding driving dis/courtesy, in comparison, is scant, with a handful of studies examining the dis/courteous driving behaviour of road users, and the relationship between driving discourtesy and driving stress. To examine courteous and discourteous driving experiences, and to explore the impact of stress associated with such driving experiences. Thirty-eight drivers (20 females) from the Sunshine Coast region volunteered to participate in one of four 1-1.5 h focus groups. Content analysis used the verbatim utterances captured via an Mp3 device. Three themes pertaining to stressful and discourteous interactions were identified. Theme one pertained to the driving context: road infrastructure (eg, roundabouts, roadwork), vehicles (eg, features), location (eg, country vs city, unfamiliar areas), and temporal aspects (eg, holidays). Theme two pertained to other road users: their behaviour (eg, tailgating, merging), and unknown factors (eg, illicit and licit drug use). Theme three pertained to the self as road user: their own behaviours (eg, deliberate intimidation), and their emotions (eg, angry reaction to other drivers, being in control). Driving dis/courtesy and driving stress is a complex phenomenon, suggesting complex intervention efforts are required. Driving discourtesy was reported as being highly stressful, therefore intervention efforts which encourage driving courtesy and which foster emotional capacity to cope with stressful circumstances appear warranted.

    This study clarifies the associations between accident history, perception of the riskiness of road travel and traffic safety behaviours by taking into account the number and severity of accidents experienced. A sample of 525 road users in Cameroon answered a questionnaire comprising items on perception of risk, safe behaviour and personal accident history. Participants who reported involvement in more than three accidents or involvement in a severe accident perceived road travel as less risky and also reported behaving less safely compared with those involved in fewer, or less severe accidents. The results have practical implications for the prevention of traffic accidents. Practitioner Summary: The associations between accident history, perceived risk of road travel and safe behaviour were investigated using self-report questionnaire data. Participants involved in more than three accidents, or in severe accidents, perceived road travel as less risky and also reported more unsafe behaviour compared with those involved in fewer, or less severe accidents. Campaigns targeting people with a less serious, less extensive accident history should aim to increase awareness of hazards and the potential severity of their consequences, as well as emphasising how easy it is to take the recommended preventive actions. Campaigns targeting those involved in more frequent accidents, and survivors of serious accidents, should address feelings of invulnerability and helplessness.

    The incidence of STI is high and increasing in Bhutan. Poor understanding of risky sexual behavior could be a cause. Comprehensive community surveys have not been previously done. This study was conducted to assess local knowledge on STIs and sexual risk behaviour in two rural districts of Bhutan: Gasa and Zhemgang. The study population included residents aged 15-49 years in the two districts. Health Assistants (HAs) visited all households to distribute questionnaires assessing understanding of knowledge on STIs and risk behaviour. Questionnaires were scored and analyzed. The average score was 61.6%. Respondents had highest knowledge about prevention and lowest about disease and complications. There was a positive correlation between level of education and knowledge on STI (P sexual behavior with 31.2% having sexual relationships with non-regular partners and 10.9% had extramarital sexual contacts. Regular use of condoms with non-regular partners was 49.1%. The most common reason for not using condom was unavailability during the sexual encounter. The study showed that despite increasing knowledge there was no reduction in risky sexual behaviour (p > 0.05). The study population had variable understanding of STIs and their complications. One in three persons practiced risky sexual behaviour, higher in men. Condom use was low. There was no reduction of risky sexual behaviour with increasing level of knowledge indicating that increasing level of knowledge does not necessarily reduce risky sexual behaviour.

    This study explored the impact of personality traits on driving safety in high-speed railway drivers. A sample of high-speed railway drivers in Beijing (N=214) completed a questionnaire, including information on personality traits and background variables. The NEO Five Factor Inventory (NEO-FFI) was administered to characterize participants based on five personality traits: Neuroticism, Extraversion, Agreeableness, Openness to Experience, and Conscientiousness. The survey data were combined with naturalistic data of accident involvement and risky driving behavior in China. Poisson regression results show that drivers with high Conscientiousness and Extraversion caused fewer accidents. Higher Conscientiousness and lower Agreeableness were related to less frequent risky driving behavior. Education level and age negatively moderated the relation between certain personality traits and driving safety. The findings suggest that personality traits should be considered when selecting and training high-speed railway drivers. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Alcohol and energy drinks are commonly used substances by youth in Canada, and are often mixed (AmED). While several studies have shown that AmED can have dangerous effects, less well understood is how AmED is associated with driving under the influence of either alcohol or drugs. This study sought to determine whether youth who use AmED were more likely to engage in driving, or being a passenger of a driver, under the influence of alcohol or cannabis compared to youth who use either alcohol or energy drinks alone. This study used data from grade 10-12 students who took part in the 2014/2015 Canadian Student Tobacco, Alcohol and Drugs Survey (N=17,450). The association of past-year AmED use with past-30day: driving under the influence of alcohol or cannabis, and riding with an alcohol- or cannabis-influenced driver, was assessed using logistic regression. One in four youth had consumed AmED in the previous 12months. AmED users were more likely to engage in all risk behaviours except riding with a drinking driver, relative to youth who only consumed alcohol. No association was observed for youth who consumed alcohol and energy drinks on separate occasions. Youth who use AmED demonstrate a higher risk profile for driving under the influence of alcohol or cannabis, than youth who use alcohol alone. Future research should explore the biopsychosocial pathways that may explain why using energy drinks enhances the already heightened risk posed by alcohol on other health-related behaviours such as driving under the influence.

    Literature indicates that unlicensed driving (UD) offenders report substance use risk behaviours, yet data related to sexual risk behaviours is unknown. This study examined sexual and other risk behaviours among young adults in Miami, Florida, comparing UD and non-UD offenders (n=498). Compared with others, UD offenders were more likely to report group sex history, being high for sex half the time or more, purchasing sex and sexually transmissible infection history. Results suggest that locating sexual risk reduction interventions inside of the justice system would benefit UD offenders.

    Smoking, excessive drinking, lack of exercise and a poor diet remain key causes of premature morbidity and mortality globally, yet it is not clear what proportion of patients attending for routine primary care are eligible for interventions about these behaviours, the extent to which they co-occur within individuals, and which individuals are at greatest risk for multiple unhealthy behaviours. The aim of the trial was to examine 'intervention eligibility' and co-occurrence of the 'big four' risky health behaviours - lack of exercise, smoking, an unhealthy diet and excessive drinking - in a primary care population. Data were collected from adult patients consulting routinely in general practice across South Wales as part of the Pre-Empt study; a cluster randomised controlled trial. After giving consent, participants completed screening instruments, which included the following to assess eligibility for an intervention based on set thresholds: AUDIT-C (for alcohol), HSI (for smoking), IPAQ (for exercise) and a subset of DINE (for diet). The intervention following screening was based on which combination of risky behaviours the patient had. Descriptive statistics, χ2 tests for association and ordinal regressions were undertaken. Two thousand sixty seven patients were screened: mean age of 48.6 years, 61.9 % female and 42.8 % in a managerial or professional occupation. In terms of numbers of risky behaviours screened eligible for, two was the most common (43.6 %), with diet and exercise (27.2 %) being the most common combination. Insufficient exercise was the most common single risky behaviour (12.0 %). 21.8 % of patients would have been eligible for an intervention for three behaviours and 5.9 % for all four behaviours. Just 4.5 % of patients did not identify any risky behaviours. Women, older age groups and those in managerial or professional occupations were more likely to exhibit all four risky behaviours.

    A sample of 158 male and 357 female college students at a midwestern university participated in an on-line study of psychosocial motives for texting while driving. Men and women did not differ in self-reported ratings of how often they texted while driving. However, more women sent texts of less than a sentence while more men sent texts of 1-5 sentences. More women than men said they would quit texting while driving due to police warnings, receiving information about texting dangers, being shown graphic pictures of texting accidents, and being in a car accident. A hierarchical regression for men's data revealed that lower levels of feeling distracted by texting while driving (20% of the variance), higher levels of cell phone dependence (11.5% of the variance), risky behavioral tendencies (6.5% of the variance) and impulsivity (2.3%) of the variance) were significantly associated with more texting while driving (total model variance=42%). A separate regression for women revealed that higher levels of cell phone dependence (10.4% of the variance), risky behavioral tendencies (9.9% of the variance), texting distractibility (6.2%), crash risk estimates (2.2% of the variance) and driving confidence (1.3% of the variance) were significantly associated with more texting while driving (total model variance=31%.) Friendship potential and need for intimacy were not related to men's or women's texting while driving. Implications of the results for gender-specific prevention strategies are discussed.

    Both human and non-human animals frequently deal with risky decisions in a social environment. Nevertheless, the influence of the social context on decision-making has been scarcely investigated. Here, we evaluated for the first time whether the presence of a conspecific influences risk preferences in rats and in tufted capuchin monkeys. Subjects received a series of choices between a constant, safe option and a variable, risky option, both alone (Alone condition) and when paired with a conspecific (Paired condition). The average payoff of the risky option was always lower than that of the safe option. Overall, the two species differed in their attitude towards risk: whereas rats were indifferent between options, capuchins exhibited a preference for the safe option. In both species, risk preferences changed in the Paired condition compared to the Alone condition, although in an opposite way. Whereas rats increased their risk preferences over time when paired with a conspecific, capuchins chose the risky option less in the Paired condition than in the Alone condition. Moreover, whereas anxiety-like behaviours decreased across sessions in rats, these behaviours where more represented in the Paired condition than in the Alone condition in capuchins. Thus, our findings extends to two distantly-related non-human species the evidence, so far available for human beings, that a decrease in anxiety corresponds to an increase in risk preferences, and vice versa. This suggests that the modulation of risk preferences by social influences observed in rats and capuchin monkeys may rely on a common, evolutionarily ancient, mechanism.

    Five studies examined the effects of positive emotion priming on the willingness to drive recklessly. In all five, young drivers were exposed to one of the following primes of positive affect: a positive mood story; happy memories; an exciting film; a relaxing film; or thoughts on the meaning in life. Following the prime, the participants were asked to report on their willingness to drive recklessly. The responses were compared to those of groups exposed either to neutral affect, another kind of positive affect, or negative affect priming. In two of the studies, participants were also asked to report on their driving styles (risky, anxious, angry, or careful) as a second dependent variable. Positive affect, especially in the form of arousal, was found to be related to higher willingness to drive recklessly. Although men tended to report higher intentions to drive recklessly, men and women did not react differently to the emotional induction. Most interestingly, positive emotions of a relaxing nature, as well as thinking about the meaning in life, lowered the willingness to engage in risky driving. The discussion emphasizes the importance of looking for new ways to use positive emotions effectively in road safety interventions, and considers the practical implications of the studies.

    Motor vehicle crashes are the leading source of morbidity and mortality in adolescents in the United States and the developed world. Inadequate allocation of attention to the driving task and to driving hazards are important sources of adolescent crashes. We review major explanations for these attention failures with particular focus on the roles that brain immaturity and lack of driving experience play in causing attention problems. The review suggests that the potential for overcoming inexperience and immaturity with training to improve attention to both the driving task and hazards is substantial. Nevertheless, there are large individual differences in both attentional abilities and risky driving tendencies that pose challenges to novice driver policies. Research that can provide evidence-based direction for such policies is urgently needed. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    Crashes are the leading cause of death for teens, and parent-based interventions are a promising approach. We assess the effectiveness of Steering Teens Safe, a parent-focused program to increase safe teen driving. Steering Teens Safe aimed to improve parental communication with teens about safe driving using motivational interviewing techniques in conjunction with 19 safe driving lessons. A randomized controlled trial involved 145 parent-teen dyads (70 intervention and 75 control). Intervention parents received a 45-minute session to learn the program with four follow-up phone sessions, a DVD, and a workbook. Control parents received a standard brochure about safe driving. Scores were developed to measure teen-reported quantity and quality of parental communication about safe driving. The main outcome measure was a previously validated Risky Driving Score reported by teens. Because the Score was highly skewed, a generalized linear model based on a gamma distribution was used for analysis. Intervention teens ranked their parent's success in talking about driving safety higher than control teens (p = 0.035) and reported that their parents talked about more topics (non-significant difference). The Risky Driving Score was 21% lower in intervention compared to control teens (85% CI = 0.60, 1.00). Interaction between communication quantity and the intervention was examined. Intervention teens who reported more successful communication had a 42% lower Risky Driving Score (95% CI = 0.37, 0.94) than control parents with less successful communication. This program had a positive although not strong effect, and it may hold the most promise in partnership with other programs, such as Driver's Education or Graduated Driver's License policies.

    The pace-of-life syndrome (POLS) hypothesis predicts associations between life history and 'risky' behaviours. Individuals with 'fast' lifestyles should develop faster, reproduce earlier, exhibit more risk-prone behaviours, and die sooner than those with 'slow' lifestyles. While support for POLS has been equivocal to date, studies have relied on individual-level (phenotypic) patterns in which genetic trade-offs may be masked by environmental effects on phenotypes. We estimated genetic correlations between life history (development, lifespan, size) and risky behaviours (exploration, aggression) in a pedigreed population of Mediterranean field crickets ( Gryllus bimaculatus ). Path analyses showed that behaviours mediated some genetic relationships between life history traits, though not those involved in trade-offs. Thus, while specific predictions of POLS theory were not supported, genetic integration of behaviour and life history was present. This implies a major role for risky behaviours in life history evolution. © 2017 The Author(s).

    The present study aims to investigate differences in road safety attitude, driver behaviour and traffic risk perception between Malaysia and Singapore. A questionnaire-based survey was conducted among a sample of Singaporean (n = 187) and Malaysian (n = 313) road users. The data was analysed using confirmatory factor analysis and structural equation modelling applied to measure comparative fit indices of Malaysian and Singaporean respondents. The results show that the perceived traffic risk of Malaysian respondents is higher than Singaporean counterparts. Moreover, the structural equation modelling has confirmed perceived traffic risk performing the role of full mediation between perceived driving skills and perceived road safety for both the countries, while perceived traffic skills was found to perform the role of partial mediation between aggression and anxiety, on one hand, and road safety, on the other hand, in Malaysia and Singapore. In addition, in both countries, a weak correlation between perceived driving skills, aggression and anxiety with perceived road safety was found, while a strong correlation exists with traffic risk perception. The findings of this study have been discussed in terms of theoretical, practical and conceptual implications for both scholars and policy-makers to better understand the young drivers' attitude and behaviour relationship towards road safety measures with a view to future research.

    This paper analyses driving behaviour in car-following conditions, based on extensive individual vehicle data collected during experimental field surveys carried out in Italy and the UK. The aim is to contribute to identify simple evidence to be exploited in the ongoing process of driving assistance and automation which, in turn, would reduce rear-end crashes. In particular, identification of differences and similarities in observed car-following behaviours for different samples of drivers could justify common tuning, at a European or worldwide level, of a technological solution aimed at active safety, or, in the event of differences, could suggest the most critical aspects to be taken into account for localisation or customisation of driving assistance solutions. Without intending to be exhaustive, this paper moves one step in this direction. Indeed, driving behaviour and human errors are considered to be among the main crash contributory factors, and a promising approach for safety improvement is the progressive introduction of increasing levels of driving automation in next-generation vehicles, according to the active/preventive safety approach. However, the more advanced the system, the more complex will be the integration in the vehicle, and the interaction with the driver may sometimes become unproductive, or risky, should the driver be removed from the driving control loop. Thus, implementation of these systems will require the interaction of human driving logics with automation logics and then an enhanced ability in modelling drivers' behaviour. This will allow both higher active-safety levels and higher user acceptance to be achieved, thus ensuring that the driver is always in the control loop, even if his/her role is limited to supervising the automatic logic. Currently, the driving mode most targeted by driving assistance systems is longitudinal driving. This is required in various driving conditions, among which car-following assumes key importance

    The relationship between stress and road safety has been studied for many years, but the effect of global stress and its joint effect with personality on driving behavior have received little attention in previous studies. This study aimed to elucidate the impact of global stress and various personality traits on driving behavior. 242 drivers completed the Perceived Stress Scale-10 (PSS-10), the Dula Dangerous Driving Index (DDDI), and several personality trait scales related to anger, sensation seeking, and altruism. The results showed that perceived stress and sensation seeking were significantly correlated with the four subcategories of dangerous driving behavior, namely, negative cognitive/emotional driving (NCED), aggressive driving (AD), risky driving (RD), and drunk driving (DD). Moreover, anger was positively correlated with negative cognitive/emotional driving, aggressive driving, and risky driving, and altruism was negatively correlated with aggressive driving and drunk driving. Hierarchical multiple regressions were applied to analyze the mediating effect of personality traits, and the results showed that anger mediated the relationship between stress and dangerous driving behavior and that this mediating role was especially strong for negative cognitive/emotional driving and aggressive driving. Collectively, the results showed that stress is an important factor that can affect people's driving behavior but that personality traits mediate the effect of stress on driving behavior. The findings from this study regarding the relationship among stress, anger, and dangerous driving behavior could be applied in the development of intervention programs for stress and anger management in order to improve drivers' ability to manage emotional thoughts and adjust their behavior on the road.

    Diabetes mellitus is a disease which may affect the eligibility to hold a driving license and increase the risk of a road accident. Hypoglycemia while driving is considered to be the most risky situation, with diabetes increasing the mentioned risk for instance due to impaired vision in the case of possible retinopathy. The group of drivers with diabetes being at the greatest risk as to accidents are those with a case history of severe hypoglycemia or hypoglycemia occurred while driving, or possibly of a road accident. Measuring glycaemia before driving and their knowledge how to prevent and treat hypoglycemia - those are the two crucial preventive elements indispensable for insulin treated diabetes patients in order to secure safe road traffic.

    Texting while driving is highly prevalent among adolescents and young adults in the United States. Texting while driving can significantly increase the risk of road crashes and is associated with other risky driving behaviors. Most states have enacted distracted driving laws to prohibit texting while driving. This study examines effects of different all-driver distracted driving laws on texting while driving among high school students. High school student data were extracted from the 2013 National Youth Risk Behavior Survey. Distracted driving law information was collected from the National Conference of State Legislatures. The final sample included 6,168 high school students above the restricted driving age in their states and with access to a vehicle. Logistic regression was applied to estimate odds ratios of laws on texting while driving. All-driver text messaging bans with primary enforcement were associated with a significant reduction in odds of texting while driving among high school students (odds ratio = 0.703; 95% confidence interval, 0.513-0.964), whereas all-driver phone use bans with primary enforcement did not have a significant association with texting while driving (odds ratio = 0.846; 95% confidence interval, 0.501-1.429). The findings indicate that all-driver distracted driving laws that specifically target texting while driving as opposed to all types of phone use are effective in reducing the behavior among high school students.

    Novice drivers are overrepresented in traffic collisions, especially in their first year of solo driving. It is widely accepted that some driving behaviours (such as speeding and thrill-seeking) increase risk in this group. Increasingly research is suggesting that attitudes and behavioural intentions held in the pre-driver and learning stage are important in determining later driver behaviour in solo driving. In this study we examine changes in several self-reported attitudes and behavioural intentions across the learning stage in a sample of learner drivers in Great Britain. A sample of 204 learner drivers completed a self-report questionnaire near the beginning of their learning, and then again shortly after they passed their practical driving test. Results showed that self-reported intentions regarding speed choice, perceptions regarding skill level, and intentions regarding thrill-seeking (through driving) became less safe over this time period, while self-reported intentions regarding following distance and overtaking tendency became safer. The results are discussed with reference to models of driver behaviour that focus on task difficulty; it is suggested that the manner in which behind-the-wheel experience relates to the risk measures of interest may be the key determining factor in how these change over the course of learning to drive.

    Adolescence and young adulthood is a time of risky health behaviour initiation and experimentation. Smoking, risky drinking, poor nutrition and physical activity, and a lack of sun protection behaviour, often become established in early adulthood. Levels of health risk behaviours occurring amongst tertiary education and training students and their preferences for types of on-campus health promotion programs were examined. A cross-sectional pen-and-paper classroom survey was conducted at one Sydney-based TAFE New South Wales Institute campus in May 2010. The survey assessed demographics, smoking, alcohol use, sun protection, nutrition, physical activity and health promotion program preferences. Two hundred and twenty-four students participated (97% consent); the majority were aged 16-24 years (59%) and female (51%). Current smoking (35%), risky drinking (49%) and inadequate physical activity (88%) rates were high. Adequate vegetable intake (3.6%) and sun protection behaviours (5.4%) were low and 33% of students were overweight or obese. Popular health promotion programs included food and activity subsidies, practical skills classes and social outings. Participation in health risk behaviours among this sample was high. The setting of tertiary education and workplace training represents an opportunity for early intervention into risky health behaviours among young people. SO WHAT?: This study is the first to provide information on the prevalence of health risk behaviours and preferences for types of health promoting programs among students of an Australian community college. The results show that young adults regularly participate in multiple health risk behaviours, such as smoking, drinking, poor nutrition, physical activity and lack of sun protection.

    The question of how urbanisation and poverty are linked in sub-Saharan Africa is an increasingly pressing one. The urban character of the HIV epidemic in sub-Saharan Africa exacerbates concern about the urbanisation - poverty relationship. Recent empirical work has linked urban poverty, and particularly slum residence, to risky sexual behaviour in Kenya's capital city, Nairobi. This paper explores the generalisability of these assertions about the relationship between urban poverty and sexual behaviour using Demographic and Health Survey data from five African cities: Accra (Ghana), Dar-es-Salaam (Tanzania), Harare (Zimbabwe), Kampala (Uganda) and Nairobi (Kenya). The study affirms that, although risky behaviour varies across the five cities, slum residents demonstrate riskier sexual behaviour compared with non-slum residents. There is earlier sexual debut, lower condom usage and more multiple sexual partners among women residing in slum households regardless of setting, suggesting a relatively uniform effect of urban poverty on sexual risk behaviour.

    It has been estimated that one-third of all work-related deaths occur while driving for work-related purposes. Despite this, many organisations are unaware of the practices, beyond those that identify and control the impact of unforeseen events (i.e., risk management), that predispose drivers to risk. This study addresses the issue by identifying the management practices operationalised as, High Performance Workplace Systems (HPWS) that influence safe driver behaviour. The study also explores the value given to safety by senior level management as a moderator of the relationship between HPWS practices and driver behaviour. Each factor was tested within a two level hierarchical model consisting of 911 drivers, nested within 161 supervisors and 83 organisations. The findings highight that under conditions of high investment in job and work design, communication and selection practices, drivers reported poorer driving behaviour. An interaction effect also demonstrated that under conditions of high investment in remuneration, drivers reported safer behaviour, but only when they perceived that managers valued and prioritised safety. The findings challenge current thinking in the management of workplace road safety. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2018-04-30

    Background: Body hair removal is a behaviour that has become normative among women in Westernised cultures, and is presented by the media as the feminine ideal, despite being painful and a potential cause of infection. Of concern, removal may be part of a more global pattern of appearance dissatisfaction and risky sexual behaviour. The aim of the present study was to examine the relationships among pubic hair removal, body image and sexual health indicators. Methods: Women (n=264; Mage=33.82, s.d.=11.13, range=18-66) completed self-report questionnaires assessing these constructs, including an assessment of body hair removal practices. Results: Greater appearance concerns (as measured by thin-ideal internalisation, appearance investment and self-objectification) and sexual health indicators (i.e. less condom use self-efficacy when a partner disapproves of condom use) all predicted greater importance of reasons for pubic hair removal (R2=0.315, F(8184)=9.97, Pwomen who removed a greater amount of hair reported more thin-ideal internalisation and appearance investment than those who removed less hair. Conclusions: Women who express stronger reasoning for pubic hair removal, and remove a larger amount of it, may endorse problematic beliefs and behaviours particularly related to appearance concerns. It is important for practitioners to consider this practice as distinct from grooming and to be aware of its association with a broader array of risky beliefs and behaviours that can compromise women's well-being.

    Full Text Available Many automobile drivers having knowledge of the driving behaviours and habits that can lead to inefficient and unsafe driving. However it is often the case that these same drivers unknowingly manifest these inefficient and unsafe driving behaviours in their everyday driving activity. The proposed system proposes a practical and economical way to capture measure and alert drives of inefficient and unsafe driving as well as highly efficient system aimed at early detection and alert of dangerous vehicle maneuvers typically related to drunk driving. The upcoming solution consists of a mobile application running on a modern smartphone device paired with a compatible OBDII On-board diagnostics II reader.

    This study explored the impact of adolescents' playing of racing and drive'em up games on their risky driving behavior. Participants were 354 adolescent boys and girls who took part in a longitudinal panel survey on video game playing and risk taking attitudes, intentions and behaviors. In line with cultivation theory and theory of planned behavior the results showed that (even after controlling for aggression and sensation seeking) video game playing during adolescence succeeded in predicting later risky driving behavior through adolescents' attitudes and intentions to exhibit this behavior in the future. The results suggest that this relationship may in part be explained by the game content. Copyright © 2010 Elsevier Ltd. All rights reserved.

    2013-01-01

    Young novice drivers continue to be overrepresented in fatalities and injuries arising from crashes even with the introduction of countermeasures such as graduated driver licensing (GDL). Enhancing countermeasures requires a better understanding of the variables influencing risky driving. One of the most common risky behaviours performed by drivers of all ages is speeding, which is particularly risky for young novice drivers who, due to their driving inexperience, have difficulty in identifying and responding appropriately to road hazards. Psychosocial theory can improve our understanding of contributors to speeding, thereby informing countermeasure development and evaluation. This paper reports an application of Akers' social learning theory (SLT), augmented by Gerrard and Gibbons' prototype/willingness model (PWM), in addition to personal characteristics of age, gender, car ownership, and psychological traits/states of anxiety, depression, sensation seeking propensity and reward sensitivity, to examine the influences on self-reported speeding of young novice drivers with a Provisional (intermediate) licence in Queensland, Australia. Young drivers (n=378) recruited in 2010 for longitudinal research completed two surveys containing the Behaviour of Young Novice Drivers Scale, and reported their attitudes and behaviours as pre-Licence/Learner (Survey 1) and Provisional (Survey 2) drivers and their sociodemographic characteristics. An Akers' measurement model was created. Hierarchical multiple regressions revealed that (1) personal characteristics (PC) explained 20.3%; (2) the combination of PC and SLT explained 41.1%; (3) the combination of PC, SLT and PWM explained 53.7% of variance in self-reported speeding. Whilst there appeared to be considerable shared variance, the significant predictors in the final model included gender, car ownership, reward sensitivity, depression, personal attitudes, and Learner speeding. These results highlight the capacity for

    Full Text Available Introduction: Today, all kinds of people need vehicles for performing their daily activities. The need for use of these vehicles for transportation frequently leads to a high rate of road accidents and it seems that certain people do not have enough ability to use these vehicles. Dangerous behaviors lead to financial and life risking irreparable damages. Methods: The aim of the study was to examine the relationship between psychological characteristics (mental health, aggression, type A characteristic and driving habits. The researchers chose 110 injured men drivers and asked them to complete the Manchester Driving Behavior, Type A Characteristic, Ahvaz Aggressive and Mental Health questionnaires. The data was analyzed by Pearson's Correlation and Regression Analysis. Results: The findings showed that there is a significant relation between psychological characteristics (mental health, aggression, type A characteristic and driving habits. The regression analysis also foresees the aggressive and mental health of testers’ dangerous driving behavior. Meanwhile, Type A characteristic is not able to foresee driving behaviors. Conclusion: Risky driving is a phenomenon that leads to many irreparable damages for the society and individual. Present study suggests that in order to reduce dangers and probable damages, procurement of driving license procedures should be prolonged and drivers should be regularly assessed psychologically (personal or public. Risky drivers or the attackers who need education or consultation should attend education-consultation programs.

  11. Health literacy of older drivers and the importance of health experience for self-regulation of driving behaviour.

    2011-05-01

    This study provides much needed information on the education level of older drivers regarding the impact of health conditions and medications on personal driving safety, where they source this information, and how this knowledge influences self-regulation of driving. Random and convenience sampling secured 322 Australian drivers (63.9% males) aged 65 years and over (M = 77.35 years, SD = 7.35) who completed a telephone interview. The majority of respondents (86%) had good knowledge about health conditions (health knowledge) and driving safety, however more than 50% was classified as having poor knowledge on the effects of certain medications (medication knowledge) and driving safety. Poorer health knowledge was associated with a reduced likelihood of driving over 100 km in adjusted models. Being older and having more than one medical condition was found to increase the likelihood of self-regulation of driving. Results indicate that health knowledge was less important for predicting driving behaviour than health experience. Of great interest was that up to 85.7% of respondents reported not receiving advice about the potential impact of their medical condition and driving from their doctor. The findings indicate a need for improved dissemination of evidence-based health information and education for older drivers and their doctors. Copyright © 2010 Elsevier Ltd. All rights reserved.

    To examine pre-licensure agreement on driving expectations and predictors of teen driving expectations among parent-teen dyads. Cross-sectional survey of 163 parent-teen dyads. Descriptive statistics, weighted Kappa coefficients, and linear regression were used to examine expectations about post-licensure teen driving. Teens reported high pre-licensure unsupervised driving (N = 79, 48.5%) and regular access to a car (N = 130, 81.8%). Parents and teens had low agreement on teen driving expectations (eg, after dark, κw = 0.23). Each time teens currently drove to/from school, their expectation of driving in risky conditions post-licensure increased (β = 0.21, p = .02). Pre-licensure improvement of parent-teen agreement on driving expectations are needed to have the greatest impact on preventing teens from driving in high risk conditions.

    In the United States, one third of all deaths in teens are a result of motor vehicle crashes, accounting for 6,000 deaths annually. Injury Free Coalition for Kids-Worcester in collaboration with Worcester Juvenile Court has developed an interactive program for first-time teenaged driving offenders, Reality Intensive Driver Education (Teen RIDE). This full-day program at the trauma center provides a realistic exposure to the consequences of risky driving behaviors. This article examined the driving offense recidivism rates for Teen RIDE participants versus a comparison group (CG). The intervention group (IG) consists of teenagers between 13 years and 17 years who have been arrested for the first time for a serious driving offense and are sentenced by a Worcester Juvenile Court Judge or Magistrate to the Teen RIDE program. They are required to attend the program as a condition of probation, so attendance is mandatory. Each participant in the IG completed the program and was tracked for driving reoffenses for 6 months after completion of the course. The CG consists of also first-time driving offenders. The CG was matched with the IG with respect to age (13-17 years), sex, and offense type. Springfield, Massachusetts, serves as the site for recruitment of the CG, since it is demographically similar to Worcester but 60 mi away. Students in the CG had no exposure to this program. Each CG member was also tracked for 6 months after arrest. The recidivism rate for Teen RIDE participants 6 months after the course is 6% with 0% reoffending more than once. The CG has a recidivism rate of 56% 6 months after the arrest and 14% have more than one reoffense. The CG is 13.062 (4.296-39.713) times more likely to reoffend, and this is significant (p Teen RIDE program provides an impactful exposure of the consequences of risky driving behaviors to teenaged participants. In addition, Teen RIDE participants are significantly less likely to reoffend after completion of the course

    Research indicates that using a cell phone to talk or text while maneuvering a vehicle impairs driving performance. However, few published studies directly compare the distracting effects of texting using a hands-free (i.e., speech-based interface) versus handheld cell phone, which is an important issue for legislation, automotive interface design and driving safety training. This study compared the effect of speech-based versus handheld text entries on simulated driving performance by asking participants to perform a car following task while controlling the duration of a secondary text-entry task. Results showed that both speech-based and handheld text entries impaired driving performance relative to the drive-only condition by causing more variation in speed and lane position. Handheld text entry also increased the brake response time and increased variation in headway distance. Text entry using a speech-based cell phone was less detrimental to driving performance than handheld text entry. Nevertheless, the speech-based text entry task still significantly impaired driving compared to the drive-only condition. These results suggest that speech-based text entry disrupts driving, but reduces the level of performance interference compared to text entry with a handheld device. In addition, the difference in the distraction effect caused by speech-based and handheld text entry is not simply due to the difference in task duration. Copyright © 2014 Elsevier Ltd.

    A lack of behavioural engagement in health promotion or disease prevention is a problem across many health domains. In these cases where people face a genuine danger, a reduced focus on threat and low levels of anxiety or worry are maladaptive in terms of promoting protection or prevention behaviour. Therefore, it is possible that increasing the processing of threat will increase worry and thereby enhance engagement in adaptive behaviour. Laboratory studies have shown that cognitive bias modification (CBM) can increase or decrease anxiety and worry when increased versus decreased processing of threat is encouraged. In the current study, CBM for interpretation (CBM-I) is used to target engagement in sun protection behaviour. The goal was to investigate whether inducing a negative rather than a positive interpretation bias for physical threat information can enhance worry elicited when viewing a health campaign video (warning against melanoma skin cancer), and consequently lead to more adaptive behaviour (sun protection). Participants were successfully trained to either adopt a positive or negative interpretation bias using physical threat scenarios. However, contrary to expectations results showed that participants in the positive training condition reported higher levels of worry elicited by the melanoma video than participants in the negative training condition. Video elicited worry was, however, positively correlated with a measure of engagement in sun protection behaviour, suggesting that higher levels of worry do promote adaptive behaviour. These findings imply that more research is needed to determine under which conditions increased versus decreased processing of threat can drive adaptive worry. Various potential explanations for the current findings and suggestions for future research are discussed.

    Philosophers and psychologists have long been interested in identifying factors that influence moral judgment. In the current analysis, we compare the literatures on moral psychology and decision making under uncertainty to propose that utilitarian choices are driven by the same forces that lead to risky choices. Spanning from neurocognitive to hormonal to interpersonal levels of analysis, we identify six antecedents that increase both utilitarian and risky choices (ventromedial prefrontal cortex brain lesions, psychopathology, testosterone, incidental positive affect, power, and social connection) and one antecedent that reduces these choices (serotonin activity). We identify the regulation of negative affect as a common mechanism through which the effects of each antecedent on utilitarian and risky choices are explained. By demonstrating that the same forces and the same underlying mechanism that produce risky choices also promote utilitarian choices, we offer a deeper understanding of how basic psychological systems underlie moral judgment. © The Author(s) 2015.

    2014-01-01

    Novice teen drivers have long been known to have an increased risk of crashing, as well as increased tendencies toward unsafe and risky driving behaviors. Teens are unique as drivers for several reasons, many of which have implications specifically in the area of distracted driving. This paper reviews several of these features, including the widespread prevalence of mobile device use by teens, their lack of driving experience, the influence of peer passengers as a source of distraction, the role of parents in influencing teens’ attitudes and behaviors relevant to distracted driving and the impact of laws designed to prevent mobile device use by teen drivers. Recommendations for future research include understanding how engagement in a variety of secondary tasks by teen drivers affects their driving performance or crash risk; understanding the respective roles of parents, peers and technology in influencing teen driver behavior; and evaluating the impact of public policy on mitigating teen crash risk related to driver distraction.

    As China continues to motorise rapidly, solutions are needed to reduce the burden of road trauma that is spread inequitably across the community. Little is currently known about how new drivers are trained to deal with on-road challenges, and little is also known about the perceptions, behaviours and attitudes of road users in China. This paper reports on a pilot study conducted in a driver retraining facility in one Chinese city where people who have had their licence suspended for accrual of 12 demerit points in a one year period must attend compulsory retraining in order to regain their licence. A sample of 239 suspended drivers responded to an anonymous questionnaire that sought information about preferred driving speeds and perceptions of safe driving speeds across two speed zones. Responses indicated that speeds higher than the posted limits were commonly reported, and that there was incongruence between preferred and safe speeds, such that a greater proportion of drivers reported preferred speeds that were substantially faster than what were reported as safe speeds. Participants with more driving experience reported significantly fewer crashes than newly licensed drivers (less than 2 years licensed) but no differences were found in offences when compared across groups with different levels of driving experience. Perceptions of risky behaviours were assessed by asking participants to describe what they considered to be the most dangerous on-road behaviours. Speeding and drink driving were the most commonly reported by far, followed by issues such as fatigue, ignoring traffic rules, not obeying traffic rules, phone use while driving, and non-use of seatbelts, which attracted an extremely low response which seems consistent with previously reported low belt wearing rates, unfavourable attitudes towards seatbelt use, and low levels of enforcement. Finally, observations about culturally specific considerations are made from previous research conducted by the

    The role of cannabis consumption in traffic crashes is unclear and the causal link between cannabis and collisions is still to be demonstrated. While cannabis use is very likely to impair driving ability, there is as yet no overwhelming evidence that cannabis use in isolation contributes more to collisions than other characteristics inherent to cannabis users. As noted in a growing body of literature, individuals driving under the influence of cannabis (DUIC) seem to exhibit a general reckless driving style putting them at higher risk to be involved in traffic crashes. This study aims at investigating the relationship between self-reported DUIC and reckless driving by means of self-reported measures and direct observations made in a driving simulator. Participants (n=72) were required to be between 18 and 25 years of age, to hold a valid driver's license, and to drive at least twice a week. They completed standard driving simulation tasks recreating everyday on-road trivial conditions. Results show that people admitting that they commit more real-life dangerous driving behaviors reached higher maximum speed and demonstrated more reckless driving behaviors on the driving simulation tasks. Self-reported DUIC is associated with a risky driving style including a broad range of reckless on-road behaviors and support the problem driving behavior theory. Moreover, beyond confounding factors, both self-report DUIC and observed dangerous behaviors are associated with real-life traffic violations. Since DUIC appears to be related to an overall reckless style of driving, it is proposed that public safety policies should be more holistic, simultaneously targeting multiple on-road dangerous behaviors for intervention.

    The impairing effect from sleepiness is a major contributor to road crashes. The ability of a sleepy driver to perceive their level of sleepiness is an important consideration for road safety as well as the type of sleepiness countermeasure used by drivers as some sleepiness countermeasures are more effective than others. The aims of the current study were to determine the extent that the signs of driver sleepiness were associated with sleepy driving behaviours, as well as determining which individual factors (demographic, work, driving, and sleep-related factors) were associated with using a roadside or in-vehicle sleepiness countermeasure. A sample of 1518 Australian drivers from the Australian State of New South Wales and the neighbouring Australian Capital Territory took part in the study. The participants' experiences with the signs of sleepiness were reasonably extensive. A number of the early signs of sleepiness (e.g., yawning, frequent eye blinks) were related with continuing to drive while sleepy, with the more advanced signs of sleepiness (e.g., difficulty keeping eyes open, dreamlike state of consciousness) associated with having a sleep-related close call. The individual factors associated with using a roadside sleepiness countermeasure included age (being older), education (tertiary level), difficulties getting to sleep, not continuing to drive while sleepy, and having experienced many signs of sleepiness. The results suggest that these participants have a reasonable awareness and experience with the signs of driver sleepiness. Factors related to previous experiences with sleepiness were associated with implementing a roadside countermeasure. Nonetheless, the high proportions of drivers performing sleepy driving behaviours suggest that concerted efforts are needed with road safety campaigns regarding the dangers of driving while sleepy.

    Acute stress may escalate risky decision-making in men, while there is no such effect in women. Although first evidence links these gender-specific effects of stress to stress-induced changes in cortisol, whether elevated cortisol is indeed sufficient to boost risk-taking, whether a potential cortisol effect depends on simultaneous noradrenergic activation, and whether cortisol and noradrenergic activation exert distinct effects on risk-taking in men and women is unknown. In this experiment, we therefore set out to elucidate the impact of cortisol and noradrenergic stimulation on risky decision-making in men and women. In a fully-crossed, placebo-controlled, double-blind design, male and female participants received orally either a placebo, hydrocortisone, yohimbine, an alpha-2-adrenoceptor-antagonist leading to increased noradrenergic stimulation, or both drugs before completing the balloon analogue risk task, a validated measure of risk-taking. Overall, participants' choice was risk-sensitive as reflected in reduced responding in high- compared to moderate- and low-risk conditions. Cortisol, however, led to a striking increase in risk-taking in men, whereas it had no effect on risk-taking behavior in women. Yohimbine had no such effect and the gender-specific effect of cortisol was not modulated by yohimbine. Our data show that cortisol boosts risk-taking behavior in men but not in women. This differential effect of cortisol on risk-taking may drive gender differences in risky decision-making under stress. Copyright © 2017 Elsevier Ltd. All rights reserved.

  13. Statistical and time domain signal analysis of the thermal behaviour of wind turbine drive train components under dynamic operation conditions

    International Nuclear Information System (INIS)

    2012-01-01

    Gearboxes and generators are fundamental components of all electrical machines and the backbone of all electricity generation. Since the wind energy represents one of the key energy sources of the future, the number of wind turbines installed worldwide is rapidly increasing. Unlike in the past wind turbines are more often positioned in arctic as well as in desert like regions, and thereby exposed to harsh environmental conditions. Especially the temperature in those regions is a key factor that defines the design and choice of components and materials of the drive train. To optimize the design and health monitoring under varying temperatures it is important to understand the thermal behaviour dependent on environmental and machine parameters. This paper investigates the behaviour of the stator temperature of the double fed induction generator of a wind turbine. Therefore, different scenarios such as start of the turbine after a long period of no load, stop of the turbine after a long period of full load and others are isolated and analysed. For each scenario the dependences of the temperature on multiple wind turbine parameters such as power, speed and torque are studied. With the help of the regression analysis for multiple variables, it is pointed out which parameters have high impact on the thermal behaviour. Furthermore, an analysis was done to study the dependences in the time domain. The research conducted is based on 10 months of data of a 2 MW wind turbine using an adapted data acquisition system for high sampled data. The results appear promising, and lead to a better understanding of the thermal behaviour of a wind turbine drive train. Furthermore, the results represent the base of future research of drive trains under harsh environmental conditions, and it can be used to improve the fault diagnosis and design of electrical machines.

    Alcohol is the root cause of numerous traffic accidents due to its pharmacological action on the human central nervous system. This study conducted a detection process to distinguish drunk driving from normal driving under simulated driving conditions. The classification was performed by a support vector machine (SVM) classifier trained to distinguish between these two classes by integrating both driving performance and physiological measurements. In addition, principal component analysis was conducted to rank the weights of the features. The standard deviation of R-R intervals (SDNN), the root mean square value of the difference of the adjacent R-R interval series (RMSSD), low frequency (LF), high frequency (HF), the ratio of the low and high frequencies (LF/HF), and average blink duration were the highest weighted features in the study. The results show that SVM classification can successfully distinguish drunk driving from normal driving with an accuracy of 70%. The driving performance data and the physiological measurements reported by this paper combined with air-alcohol concentration could be integrated using the support vector regression classification method to establish a better early warning model, thereby improving vehicle safety.

    2015-07-16

    The increasing prevalence of HIV in Uganda during the last decade (7.5% in 2004-05 to 8.3% in 2011 among women and 5.0% in 2004-05 to 6.1% among men in 2011 of 15 to 49 years) clearly shows that women are disproportionately affected by HIV epidemic. Hence, we assessed the prevalence of HIV and focused on differences in risky sexual behaviour and knowledge of HIV among Ugandan youth. Uganda AIDS Indicator Survey 2011 data was used. The total samples of men and women (15 to 24 years), interviewed and tested for HIV, were 3450 and 4504 respectively. The analysis of risky sexual behaviour was based on 1941 men and 3127 women who had ever had sex and were tested for HIV. Pearson's Chi-square test and multivariate logistic regression analysis were used. Findings showed that young women were almost two times more vulnerable than young men in acquiring HIV (OR=1.762, Pgap in risky sexual behaviour and new transmission of HIV in Uganda. Significance for public healthThe present study represents the evidence of a recent increase in HIV infection in Uganda from the latest round of AIDs indicator survey. This manuscript describes how young women (15-24 years-old) are disproportionately HIV-infected compared to young men in Uganda. They are more vulnerable to HIV than young men. Moreover, it is also observed that young women are at greater risk of acquiring HIV because of their risky sexual behaviour and inappropriate knowledge of HIV transmission. Some educational programmes, growing gender equity in HIV/AIDS activities and services, dropping violence and coercion, addressing male norms and behaviours, improving women's legal protection, and rising women's access to income and productive resources can be very effective in minimising the vulnerability of young women to HIV/AIDS.

  18. Concealing their communication: exploring psychosocial predictors of young drivers' intentions and engagement in concealed texting.

    Making a conscious effort to hide the fact that you are texting while driving (i.e., concealed texting) is a deliberate and risky behaviour involving attention diverted away from the road. As the most frequent users of text messaging services and mobile phones while driving, young people appear at heightened risk of crashing from engaging in this behaviour. This study investigated the phenomenon of concealed texting while driving, and utilised an extended Theory of Planned Behaviour (TPB) including the additional predictors of moral norm, mobile phone involvement, and anticipated regret to predict young drivers' intentions and subsequent behaviour. Participants (n=171) were aged 17-25 years, owned a mobile phone, and had a current driver's licence. Participants completed a questionnaire measuring their intention to conceal texting while driving, and a follow-up questionnaire a week later to report their behavioural engagement. The results of hierarchical multiple regression analyses showed overall support for the predictive utility of the TPB with the standard constructs accounting for 69% of variance in drivers' intentions, and the extended predictors contributing an additional 6% of variance in intentions over and above the standard constructs. Attitude, subjective norm, PBC, moral norm, and mobile phone involvement emerged as significant predictors of intentions; and intention was the only significant predictor of drivers' self-reported behaviour. These constructs can provide insight into key focal points for countermeasures including advertising and other public education strategies aimed at influencing young drivers to reconsider their engagement in this risky behaviour.

    Full Text Available In the world there are tendencies of early entering into sexual relations and simultaneous withdrawal of the age of marriage, an increase in the number of early pregnancies and abortions among minors. Existing programs for the prevention of risky sexual behavior are ineffective, since they are one-time, narrowly focused. The author presents the results of an experiment on the prevention of risky sexual behavior in adolescents based on the formation of their ideas of parenting and child-parent relations, and through the prism of this topic, allowing to build an image of reproductive behavior in the present and future. The program is designed taking into account the psychology of modern adolescents, in accordance with the principles of awareness and responsibility, is based on a restorative approach and resource approach to the formation of psychological readiness for parenthood M.E. Lantsburg. The program for the development of psychological preparedness for parenting in adolescents has two targets: the nearest: preventing adolescent pregnancy and reducing its negative consequences in the event of an early pregnancy, and strategic - preparing for the planning and birth of the coveted child in the future. The results prove that the adolescents' views about the family depend both on the experiences they experienced in their own childhood and on the trends in the social and political space discussed in this topic. The study showed that adolescents' views on sexual relations, family and parenthood can be purposefully influenced through a program based on the knowledge of age-related psychology, resource and recovery approaches and using interactive methods of teaching relevant to this age group.

    2014-10-24

    This paper discusses the overall design and implementation of a video sensor for the detection of risky behaviors of car drivers near previously identified and georeferenced black spots. The main goal is to provide the driver with a visual audio alert that informs of the proximity of an area of high incidence of highway accidents only if their driving behavior could result in a risky situation. It proposes a video sensor for detecting and supervising driver behavior, its main objective being manual distractions, so hand driver supervision is performed. A GPS signal is also considered, the GPS information is compared with a database of global positioning Black Spots to determine the relative proximity of a risky area. The outputs of the video sensor and GPS sensor are combined to evaluate a possible risky behavior. The results are promising in terms of risk analysis in order to be validated for use in the context of the automotive industry as future work.

The main goal is to provide the driver with a visual audio alert that informs of the proximity of an area of high incidence of highway accidents only if their driving behavior could result in a risky situation. It proposes a video sensor for detecting and supervising driver behavior, its main objective being manual distractions, so hand driver supervision is performed. A GPS signal is also considered, the GPS information is compared with a database of global positioning Black Spots to determine the relative proximity of a risky area. The outputs of the video sensor and GPS sensor are combined to evaluate a possible risky behavior. The results are promising in terms of risk analysis in order to be validated for use in the context of the automotive industry as future work.

    By applying unitive vocabulary, "die" or "save," to respective frames of the Asian disease problem, Tversky and Kahneman were able to define framing effect. In this study, we preliminarily explored the effect of mixed frames, which are characterized by the use of different vocabulary in one frame. In study 1, we found that only the sure option description had significant effect on decision-making, while the effects of risky option descriptions were not significant, nor were interactions between descriptions. In study 2, the results suggested that after controlling the effects of the hedonic tone of the sure options, risky option description did not significantly predict decision-making. In study 3, we found that neither the sure-to-risky option presentation order nor presentation order within risky options had significant effect on decision-making. We thus concluded that sure option description can serve as the decision-making foundation (reference point) for decision-makers in mixed frames.

    Improving safety at railway level crossings is an important issue for the Australian transport system. Governments, the rail industry and road organisations have tried a variety of countermeasures for many years to improve railway level crossing safety. New types of intelligent transport system (ITS) interventions are now emerging due to the availability and the affordability of technology. These interventions target both actively and passively protected railway level crossings and attempt to address drivers' errors at railway crossings, which are mainly a failure to detect the crossing or the train and misjudgement of the train approach speed and distance. This study aims to assess the effectiveness of three emerging ITS that the rail industry considers implementing in Australia: a visual in-vehicle ITS, an audio in-vehicle ITS, as well as an on-road flashing beacons intervention. The evaluation was conducted on an advanced driving simulator with 20 participants per trialled technology, each participant driving once without any technology and once with one of the ITS interventions. Every participant drove through a range of active and passive crossings with and without trains approaching. Their speed approach of the crossing, head movements and stopping compliance were measured. Results showed that driver behaviour was changed with the three ITS interventions at passive crossings, while limited effects were found at active crossings, even with reduced visibility. The on-road intervention trialled was unsuccessful in improving driver behaviour; the audio and visual ITS improved driver behaviour when a train was approaching. A trend toward worsening driver behaviour with the visual ITS was observed when no trains were approaching. This trend was not observed for the audio ITS intervention, which appears to be the ITS intervention with the highest potential for improving safety at passive crossings.

    2017-11-01

    Ageing drivers experience a higher risk of intersection crashes because of their decrease in driving efficiency, including the decline in cognitive ability, head and neck flexibility, and visual acuity. Although several studies have been conducted to examine the factors associated with ageing driver crashes at intersections, little research has been conducted to examine the differences in the factors related to ageing drivers' turning paths and intersection geometric features. This study aims to improve the safety of ageing drivers at intersections by identifying the maneuvers that are risky for them and tracking their turning movements at selected intersections. We find that ageing drivers experience more crashes at intersections than younger drivers, especially crashes involving turning movements. Furthermore, ageing drivers experience more crashes at unchannelized intersections compared to channelized intersections. In addition, this study finds that ageing drivers exhibit greater and more inconsistent offsets during turning movements compared to those of younger drivers at both channelized and unchannelized intersections. Ageing drivers also tend to make relatively sharper or tighter turns than younger drivers. Hence, transportation engineers and road safety professionals should consider appropriate countermeasures to reduce the risks of crashes involving ageing drivers at intersections.

    Background Early callous–unemotional behaviours identify children at risk for antisocial behaviour. Recent work suggests that the high heritability of callous–unemotional behaviours is qualified by interactions with positive parenting. Aims To examine whether heritable temperament dimensions of fearlessness and low affiliative behaviour are associated with early callous–unemotional behaviours and whether parenting moderates these associations. Method Using an adoption sample (n = 561), we examined pathways from biological mother self-reported fearlessness and affiliative behaviour to child callous–unemotional behaviours via observed child fearlessness and affiliative behaviour, and whether adoptive parent observed positive parenting moderated pathways. Results Biological mother fearlessness predicted child callous–unemotional behaviours via earlier child fearlessness. Biological mother low affiliative behaviour predicted child callous–unemotional behaviours, although not via child affiliative behaviours. Adoptive mother positive parenting moderated the fearlessness to callous–unemotional behaviour pathway. Conclusions Heritable fearlessness and low interpersonal affiliation traits contribute to the development of callous–unemotional behaviours. Positive parenting can buffer these risky pathways.

    Full Text Available This study sheds light on the investment portfolio’s decisions through behavioral insights. The study intends to identify personal characteristics that drive the level of diversification and lead investors to allocate resources in risky assets in an emergent economy, deepening the discussion about investment decisions and bringing some behavioral insights to the debate. The study has a unique and heterogeneous database of individual financial allocations from Brazil, one of the largest emergent economies. The characteristics of Brazilian investors play an important role in investment decisions, high educated and married investors tend to display diversified portfolios. To invest in risky assets, male investors have a 43% greater likelihood of investing in risky assets than females, highlighting the discussion on gender and investment decisions. Moreover, married investors tend to exhibit conservative portfolios. We observed that traditional investors are under-diversified, allocating primarily in traditional and safety assets. The results suggest that the investment decisions can be subject to psychological biases defined in behavioral finance theory.

    To investigate how exposure to sex, alcohol and violent content in mainstream and Black-oriented movies relates to corresponding adolescent behavior among Black youth from the United States and whether those relationships are moderated by ethnic identity. The present study uses survey data from an online sample of 1000 Black adolescents and content analysis ratings on top-grossing 2014 films and 2013/2014 Black-oriented films. Content-specific exposure measures for alcohol, sexual activity, and violence were calculated from self-reported exposure data and content analysis ratings. Regression analyses estimated the associations among exposures to risky health content in mainstream and Black-oriented films and adolescent behaviors as well as moderation by ethnic group identity. Black adolescents were mostly unaffected by exposure to risk portrayals in mainstream films, but exposure to risk in Black-oriented films was related to their behavior in all three domains. Strong group identity strengthened the relationship between exposure to sex in Black-oriented and mainstream films depending on the sexual outcome. The type of movie (i.e., mainstream or Black-oriented) through which Black adolescents are exposed to risky health portrayals is important for understanding its relationship to their behavior, and variations by ethnic identity were limited to sex content. Future research should identify the mechanisms through which risk content in Black-oriented films is associated with Black adolescents' risky behaviors to determine how media influence contributes to behavioral disparities among youth.

    2012-05-01

    Full Text Available Problem: The number of killed and injured persons in incidents at railway level crossings is generally increasing on the Serbian Railways, particularly at passive crossings. In this paper we researched the direct behaviour of road traffic participants at a conventional railway passive crossing. Method: Direct observational study of drivers’ behaviour at a level crossing. Results: Sixty-one road vehicle drivers were observed in the moments of train approach. The probability of crossing varies depending on the train distance and the time the driver has to cross the crossing. The drivers who have limited visibility cannot estimate the speed of the approaching train well and make more risky decisions. Conclusion: This study shows that the number of “risky crossings” is worrying as the result of such crossings is a large number of accidents with fatal consequences at the passive crossings in Serbia.

    Traffic safety climate is defined as road users' attitudes and perceptions of traffic in a specific context at a given point in time. The current study aimed to validate the Chinese version of the Traffic Climate Scale (TCS) and to explore its relation to drivers' personality and dangerous driving behavior. A sample of 413 drivers completed the Big Five Inventory (BFI), the Chinese version of the TCS, the Dula Dangerous Driving Index (DDDI) and a demographic questionnaire. Exploratory factor analysis and confirmatory factor analysis were performed to confirm a three-factor (external affective demands, internal requirements and functionality) solution of the TCS. The reliability and validity of the Chinese version of TCS were verified. More importantly, the results showed that the effect of personality on dangerous driving behavior was mediated by traffic climate. Specifically, the functionality of the TCS mediated the effect of neuroticism on negative cognitive/emotional driving and drunk driving, while openness had an indirect impact on aggressive driving, risky driving and drunk driving based on the internal requirements of the TCS. Additionally, agreeableness had a negative direct impact on four factors of the DDDI, while neuroticism had a positive direct impact on negative cognitive/emotional driving, drunk driving and risky driving. In conclusion, the Chinese version of the TCS will be useful to evaluate drivers' attitudes towards and perceptions of the requirements of traffic environment in which they participate and will also be valuable for comparing traffic cultures and environments in different countries.

    2012-09-01

    The primary purposes of this study were to explore the relationship between risk-taking acts while driving motorcycles and perceived causes of motorcycle accidents, as well as their contribution to active involvement in traffic accidents among Chinese motorcyclists in Hong Kong. Active involvement means the riders was likely at fault for the crash. A total of 774 motorcyclists were recruited, of whom 292 had been involved in active motorcycle accident in the previous 3 years. All were asked to fill in a questionnaire, which was developed to assess their risk-taking acts while driving a motorcycle and perception of motorcycle accident causes. The results of the study revealed 3 dimensions of accident causes, namely, driving-related, environment-related, and belief-related causes. These motorcycle accident causes were correlated with risk-taking acts while driving a motorcycle. A multivariate logistic regression analysis showed that risk-taking acts while driving motorcycles (adjusted odds ratio [OR]: 1.036, 95% confidence interval [CI]: 1.020-1.052), perception of driving-related cause (adjusted OR: 0.941, 95% CI: 0.916-0.967), and belief-related cause (adjusted OR: 1.134, 95% CI: 1.088-1.182) were significant factors contributing to involvement in active traffic accidents by motorcycle riders after controlling for concurrent demographic variables. The study highlights that perceived causes of motorcycle accidents are multidimensional, including those areas related to driving, the environment, and beliefs. It substantiates previous studies that a higher degree of driving-related risk perception is related to a lower degree of risk-taking acts while driving. Further research is needed to understand why belief-related causes, sometimes called superstitions, lead riders to believe that it is beyond their ability to affect accident causation and prevention.

    Given the increasing vehicle numbers and expanding road construction in developing countries, the importance of safe road user behaviour is critical. Road traffic crashes (RTCs) are a significant problem in Pakistan; however, the factors that contribute to RTCs in Pakistan are not well researched. Fatalistic beliefs are a potential barrier to the enhancement of road safety, especially participation in health-promoting and injury prevention behaviours, and also contribute to risk taking. Fatalistic beliefs relating to road safety have been found in some developing countries, although research is scarce and indicates that the nature and extent of fatalism differs in each country. Qualitative research was undertaken with a range of drivers, religious orators, police and policy makers to explore associations between fatalism, risky road use and associated issues. Findings indicate that fatalistic beliefs are pervasive in Pakistan, are strongly linked with religion, present a likely barrier to road safety messages and contribute to risky road use. Fatalism appears to be a default attribution of RTC and the intensity of belief in fate surpasses the kinds of fatalism noted in the limited existing literature. These findings have importance to developing road safety countermeasures in countries where fatalistic beliefs are strong.

  18. Acute effects of alcohol on inhibitory control and simulated driving in DUI offenders.

    The public health costs associated with alcohol-related traffic accidents have prompted considerable research aimed at identifying characteristics of individuals who drive under the influence (DUI) in order to improve treatment and prevention strategies. Survey studies consistently show that DUI offenders self-report higher levels of impulsivity compared to their nonoffending counterparts. However, little is known about how individuals with a DUI history respond under alcohol. Inhibitory control is a behavioral component of impulsivity thought to underlie risky drinking and driving behaviors. The present study examined the degree to which DUI drivers display deficits of inhibitory control in response to alcohol and the degree to which alcohol impaired their simulated driving performance. It was hypothesized that DUI offenders would display an increased sensitivity to the acute impairing effects of alcohol on simulated driving performance. Young adult drivers with a history of DUI and a demographically-comparable group of drivers with no history of DUI (controls) were tested following a 0.65 g/kg dose of alcohol and a placebo. Inhibitory control was measured by using a cued go/no-go task. Drivers then completed a driving simulation task that yielded multiple indicators of driving performance, such as within-lane deviation, steering rate, centerline crossings and road edge excursions, and drive speed. Results showed that although DUI offenders self-reported greater levels of impulsivity than did controls, no group differences were observed in the degree to which alcohol impaired inhibitory control and driving performance. The findings point to the need to identify other aspects of behavioral dysfunction underlying the self-reported impulsivity among DUI offenders, and to better understand the specific driving situations that might pose greater risk to DUI offenders. The systematic study of candidate cognitive deficits in DUI offenders will provide important

    Traffic Injuries are a major public health problem, especially among young people. However, we have not found any useful questionnaire designed in our country for the epidemiological research in this field. The objective of this study was to design and validate an easy and quickly-to-fill questionnaire aimed to collect information on how frequently university car drivers report to be involved in driving circumstances theoretically related to traffic crashes. Between 2007 and 2010, a total of 1597 young undergraduate students at the University of Granada answered a self-administered questionnaire collecting information about exposure, accidents and involvement in 28 different driving circumstances. For designing this questionnaire, an extensive literature review was carried out and the opinions of five experts in a panel were also taken into account. By applying the tetracoric correlation coefficient, we conducted a factor analysis. Internal consistency was assessed using Cronbach's alpha coefficient. Finally, we evaluated the crude and adjusted association of each identified factor with the odds for having suffered an accident. After excluding 8 circumstances, the remaining ones were grouped into three factors: the first one included ten high-prevalence circumstances and explained 31.9% of the total variability. Meanwhile, the other two factors included five circumstances each one which respectively explained 15.2% and 12.5% of the variability. Cronbach's alpha coefficients ranged between 0.816 and 0.553. When adjustments according age, sex, years in possession of the driving license and intensity of exposure were made, the first factor obtained the score more strongly associated with the accident rate (OR = 1.51; CI95%: 1.25-1.85). The final version (20 circumstances) identified three factors related to higher accident rates among the young drivers. The first one integrated, among other circumstances, the excessive speed and driving while sleepy or tired and it

  20. Risk Perception and Risk-Taking Behaviour during Adolescence: The Influence of Personality and Gender.

    This study investigated the influence of personality characteristics and gender on adolescents' perception of risk and their risk-taking behaviour. Male and female participants (157 females: 116 males, aged 13-20) completed self-report measures on risk perception, risk-taking and personality. Male participants perceived behaviours as less risky, reportedly took more risks, were less sensitive to negative outcomes and less socially anxious than female participants. Path analysis identified a model in which age, behavioural inhibition and impulsiveness directly influenced risk perception, while age, social anxiety, impulsiveness, sensitivity to reward, behavioural inhibition and risk perception itself were directly or indirectly associated with risk-taking behaviour. Age and behavioural inhibition had direct relationships with social anxiety, and reward sensitivity was associated with impulsiveness. The model was representative for the whole sample and male and female groups separately. The observed relationship between age and social anxiety and the influence this may have on risk-taking behaviour could be key for reducing adolescent risk-taking behaviour. Even though adolescents may understand the riskiness of their behaviour and estimate their vulnerability to risk at a similar level to adults, factors such as anxiety regarding social situations, sensitivity to reward and impulsiveness may exert their influence and make these individuals prone to taking risks. If these associations are proven causal, these factors are, and will continue to be, important targets in prevention and intervention efforts.

    Due to rapidly increasing greenhouse gas emissions, the transport sector is a key issue in any sustainability and climate strategy. Still, it is the one most difficult to deal with because of it's complexity and direct impact on everybody's life. Innovative transport technologies can significantly contribute to reducing emissions and energy use, but there is also a need for behavioural changes to turn down energy demand, especially in individual motorised transport. One of the most cost-effective measures in this field is Ecodriving, an energy efficient and road safety improving driving style. Nowadays, there are several stand-alone initiatives in Europe. But to strengthen Ecodriving and increase its market share it needs: - an overview of existing offers and facilities, - pilot projects with different target groups, - training courses (both for novice drivers and experienced road users), - quality standards, - scientific proof of the various benefits, - awareness raising and marketing. That's why ECO-DRIVING Europe has been initiated by the main stakeholders in Europe. It aims to change the behaviour of drivers by using technological developments, influencing legislation and supporting long term driving and mobility culture change. The Europe-wide ECO-DRIVING project (www.ecodrive.org ) tries to reach this goal by integrating Ecodriving into various policy fields such as energy, climate change, road safety, local environment, sustainable transport and legislation for driver licence procedures. By decreasing greenhouse gas emission by 10-20% compared to normal driving, Ecodriving can considerably contribute to reduce energy demand in transport and fight climate change.

    The Centre for Learning and Knowledge Management and Department of Computer Science in Engineering of the Technical University Aachen has developed a truck driving simulator which combines a driving simulation as well as traffic flow calculations to the interactive Driving Simulator (InDriveS). In real-time the effects of the driver's behaviour on the surrounding traffic are considered and vice versa. The integrative part of InDriveS is a software-in-the-loop and hardware-in-the-loop development environment. By means of this tool, all phases of development (Analysis, Design, Modelling, Simulation, Implementation as well as Testing and Evaluation) of new vehicle technologies, e.g. Information and Assistance Systems, can be realised in consideration of the road traffic and the driver's behaviour.

    This study examines the associations between fathers' driving styles, the family's general and driving-related atmosphere, and the young drivers' motivations, on one hand, and young males' driving styles, on the other. The 242 father and son pairs that participated in the study independently completed several self-report questionnaires at different points in time within the first year after licensure of the young drivers. A structural equation model (SEM) was developed, in which the contribution of fathers' driving style and their sons' perceptions of the general family relations, the family climate for road safety (FCRS), and costs and benefits of driving, to the driving styles of the young male drivers was examined. The SEM estimation results show direct as well as indirect significant effects between the various dimensions. The FCRS factors of non-commitment and messages, and the cost of thrill, were found to be the strongest mediators between the fathers' driving style and the family cohesion, on one hand, and the driving style of the young driver, on the other. These results may be useful in pointing out directions for the development of interventions that could assist in reducing the involvement of youngsters in risky driving and car crashes, and encourage safe and considerate driving.

    Full Text Available Background. The increasing prevalence of HIV in Uganda during the last decade (7.5% in 2004-05 to 8.3% in 2011 among women and 5.0% in 2004-05 to 6.1% among men in 2011 of 15 to 49 years clearly shows that women are disproportionately affected by HIV epidemic. Hence, we assessed the prevalence of HIV and focused on differences in risky sexual behaviour and knowledge of HIV among Ugandan youth. Design and Methods. Uganda AIDS Indicator Survey 2011 data was used. The total samples of men and women (15 to 24 years, interviewed and tested for HIV, were 3450 and 4504 respectively. The analysis of risky sexual behaviour was based on 1941 men and 3127 women who had ever had sex and were tested for HIV. Pearson’s Chi-square test and multivariate logistic regression analysis were used. Results. Findings showed that young women were almost two times more vulnerable than young men in acquiring HIV (OR=1.762, P<0.001. Women who had first sex under age 15 (7.3%, had more than 2 sexual partners (9.2% and did not use condom during last sex (6.4% were more HIV-positive. Higher risk was found among women (6.3% than men (2.2%. Significantly (P<0.01 less percentage (81.3% of women as compared to men (83.8% perceived that the probability of HIV transmission may be reduced by correct and consistent use of the condom during sex. Conclusions. Hence, there is an urgent need for effective strategies and programmes to raise awareness on sexual health and risky behaviour, particularly targeting the youth, which will reduce the gender gap in risky sexual behaviour and new transmission of HIV in Uganda.

    2012-11-01

    An increase in the use of pipe umbrellas made of long piles or self drilling injection anchors can be seen in conventional tunnel drives. They are used as reinforcement ahead of the face. This paper consists of investigations concerning the structural and geotechnical behaviour of such umbrellas in granular soils. The research is based on finite element method calculations using a diverse range of essential influencing factors. From the evaluation of the calculations, conclusions can be drawn about the load bearing behaviour of the umbrellas and their interaction with the surrounding ground. A forecasting model is derived in order to predict the internal forces of the umbrella elements and a design methodology is presented. (orig.)

    Texting while driving is risky but common. This study evaluated how texting using a Head-Mounted Display, Google Glass, impacts driving performance. Experienced drivers performed a classic car-following task while using three different interfaces to text: fully manual interaction with a head-down smartphone, vocal interaction with a smartphone, and vocal interaction with Google Glass. Fully manual interaction produced worse driving performance than either of the other interaction methods, leading to more lane excursions and variable vehicle control, and higher workload. Compared to texting vocally with a smartphone, texting using Google Glass produced fewer lane excursions, more braking responses, and lower workload. All forms of texting impaired driving performance compared to undistracted driving. These results imply that the use of Google Glass for texting impairs driving, but its Head-Mounted Display configuration and speech recognition technology may be safer than texting using a smartphone.

    Full Text Available Taking care of oneself is crucial for maintaining one´s psychical and physical health. In the context of risky profession this topic can play an even more important role, because it can be the source of necessary information for improvement of coping capacity when one is confronted with crisis situations. The aim of the present study is to identify the most common forms of self-care among selected risky professions. In the second part is the attention focused on the comparison of the specificities of risky to non-risky professions in self-care. Methods: For data collection Self-regulation Self-care Questionnaire by authors Hricová and Lovaš (in press is used. The sample consists of two groups. In the first one participated 156 respondents, who worked in risky professions - namely police officers (60 at the age between 22 to 55 years (average age is 36.88, SD=9.49, fire fighters (46 at the age between 22 to 62 years (average age is 35.13, SD=8.31 and paramedics (50 at the age between 25 to 55 years (average age is 40.3, SD=6.62. 76.2% of the sample are men, 19.0% are women and 4,8% didn´t state their gender. The second sample consists of 161 participants who work in administrative, industry production or IT sphere. They were at the age between 23 to 61 years (average age is 38.01, SD=10.45. 74% of the sample are men and 21.7% are women. Results and discussion: Results confirmed the dominance of psychological self-care above physical among risky professions. To the forefront gets the need to live meaningful life, to fully use one´s skills and to be satisfied with one´s life and decisions. All this needs can be assigned to the necessity of sense, which could be seen as a result of everyday contact with critical and life threaten situations. Equally important sphere of self-care is the necessity of high-quality relationships, which doesn´t mean only relationships with family or friends. It is important to highlight also relationships with

    Most developing countries have only limited information on the burden of Non Communicable Diseases (NCDs) even though rapid transitions in these NCDs have been predicted. To describe the burden of selected NCDs and associated risk behaviours in an urban university community in Nigeria. A cross-sectional survey of 525 representative staff of a University in a large city in Nigeria was conducted. In all, 27.6% were already diagnosed with at least one NCD (hypertension-21.5%, diabetes-11%, cancer 2.9%) while 67.4% reported at least one risk behaviour (unhealthy diet- 96%, sedentary living- 27.4% excessive alcohol use-5.1% and smoking- 1.9%). Multiple risk behaviours were observed in 29.9% with no significant variation by sex or age. Those 40 years and above had significantly higher prevalence of NCD, particularly for hypertension (p<0.05). Only 7%, considered themselves to be at risk of NCDs. Those whose parents had NCDs OR: 5.9 (2.4-14.5) and those who currently had NCDs OR: 3.9(1.8-8.1) perceived themselves at risk of one or more NCDs, but not those with multiple risk behaviours. The high burden of NCDs and risk behaviours in the face of limited self-perceived risk has been demonstrated and calls for urgent intervention.

  11. Reason and reaction: the utility of a dual-focus, dual-processing perspective on promotion and prevention of adolescent health risk behaviour.

    Gibbons, Frederick X; Houlihan, Amy E; Gerrard, Meg

    2009-05-01

    A brief overview of theories of health behaviour that are based on the expectancy-value perspective is presented. This approach maintains that health behaviours are the result of a deliberative decision-making process that involves consideration of behavioural options along with anticipated outcomes associated with those options. It is argued that this perspective is effective at explaining and predicting many types of health behaviour, including health-promoting actions (e.g. UV protection, condom use, smoking cessation), but less effective at predicting risky health behaviours, such as unprotected, casual sex, drunk driving or binge drinking. These are behaviours that are less reasoned or premeditated - especially among adolescents. An argument is made for incorporating elements of dual-processing theories in an effort to improve the 'utility' of these models. Specifically, it is suggested that adolescent health behaviour involves both analytic and heuristic processing. Both types of processing are incorporated in the prototype-willingness (prototype) model, which is described in some detail. Studies of health behaviour based on the expectancy-value perspective (e.g. theory of reasoned action) are reviewed, along with studies based on the prototype model. These two sets of studies together suggest that the dual-processing perspective, in general, and the prototype model, in particular, add to the predictive validity of expectancy-value models for predicting adolescent health behaviour. Research and interventions that incorporate elements of dual-processing and elements of expectancy-value are more effective at explaining and changing adolescent health behaviour than are those based on expectancy-value theories alone.

    Previous research has shown the association between stress and crash involvement. The impact of stress on road safety may also be mediated by behaviours including cognitive lapses, errors, and intentional traffic violations. This study aimed to provide a further understanding of the impact that stress from different sources may have upon driving behaviour and road safety. It is asserted that both stress extraneous to the driving environment and stress directly elicited by driving must be considered part of a dynamic system that may have a negative impact on driving behaviours. Two hundred and forty-seven public sector employees from Queensland, Australia, completed self-report measures examining demographics, subjective work-related stress, daily hassles, and aspects of general mental health. Additionally, the Driver Behaviour Questionnaire (DBQ) and the Driver Stress Inventory (DSI) were administered. All participants drove for work purposes regularly, however the study did not specifically focus on full-time professional drivers. Confirmatory factor analysis of the predictor variables revealed three factors: DSI negative affect; DSI risk taking; and extraneous influences (daily hassles, work-related stress, and general mental health). Moderate intercorrelations were found between each of these factors confirming the 'spillover' effect. That is, driver stress is reciprocally related to stress in other domains including work and domestic life. Structural equation modelling (SEM) showed that the DSI negative affect factor influenced both lapses and errors, whereas the DSI risk-taking factor was the strongest influence on violations. The SEMs also confirmed that daily hassles extraneous to the driving environment may influence DBQ lapses and violations independently. Accordingly, interventions may be developed to increase driver awareness of the dangers of excessive emotional responses to both driving events and daily hassles (e.g. driving fast to 'blow off steam

    2011-08-01

    Recent research has shown that shame activates both a restore and a protect motive (De Hooge, Zeelenberg, & Breugelmans, 2010), explaining the hitherto unexpected finding that shame can lead to both approach and avoidance behaviours. In the present article we show a clear difference in priority and development of restore and protect motives over time. Our experiment reveals that shame mainly motivates approach behaviour to restore the damaged self, but that this restore motive decreases when situational factors make it too risky or difficult to restore. In contrast, the motive to protect one's damaged self from further harm is not influenced by such situational factors. As a consequence, the approach behaviour that shame activates may change over time. These findings add to our understanding of the motivational processes and behaviours following from shame.

    This study investigated the influence of personality characteristics and gender on adolescents’ perception of risk and their risk-taking behaviour. Male and female participants (157 females: 116 males, aged 13–20) completed self-report measures on risk perception, risk-taking and personality. Male participants perceived behaviours as less risky, reportedly took more risks, were less sensitive to negative outcomes and less socially anxious than female participants. Path analysis identified a model in which age, behavioural inhibition and impulsiveness directly influenced risk perception, while age, social anxiety, impulsiveness, sensitivity to reward, behavioural inhibition and risk perception itself were directly or indirectly associated with risk-taking behaviour. Age and behavioural inhibition had direct relationships with social anxiety, and reward sensitivity was associated with impulsiveness. The model was representative for the whole sample and male and female groups separately. The observed relationship between age and social anxiety and the influence this may have on risk-taking behaviour could be key for reducing adolescent risk-taking behaviour. Even though adolescents may understand the riskiness of their behaviour and estimate their vulnerability to risk at a similar level to adults, factors such as anxiety regarding social situations, sensitivity to reward and impulsiveness may exert their influence and make these individuals prone to taking risks. If these associations are proven causal, these factors are, and will continue to be, important targets in prevention and intervention efforts. PMID:27100081

    Individuals with bulimia nervosa (BN) frequently endorse risky behaviors such as self-harm and substance use. However, no studies of BN to date have examined factors associated with engaging in individual or co-occurring risky behaviors. Given that individuals with BN often have personality psychopathology, which has been linked to symptoms and course of illness, this study sought to examine how personality may differentiate engagement in risky behaviors among BN individuals. A sample of 133 women with BN completed self-report measures of personality psychopathology at baseline, and then reported on bulimic and risky behaviors (e.g., substance misuse, self-harm) over 2 weeks using ecological momentary assessment. A series of hierarchical multiple regression analyses were conducted to examine the unique associations between state-level predictor variables (each risky behavior, e.g., substance misuse, and combination of risky behaviors, e.g., substance misuse plus self-harm) and trait-level personality constructs. Substance misuse behavior, above and beyond all other risky behaviors, was significantly associated with higher scores on trait dissocial behavior (P = 0.004). Substance misuse in BN has a unique association with dissocial behavior, a personality trait characterized by hostility, impulsivity, and entitlement. These results suggest that targeting personality variables may help facilitate more effective treatment of risky behaviors, including substance use in BN. © 2016 Wiley Periodicals, Inc.

    While the number of motor vehicle crashes has declined over the years, crashes resulting from distracted driving are increasing in the United States resulting in significant morbidity and mortality. The national public seems to be aware of the dangers associated with using technology while driving, but continues to engage in this dangerous behaviour, and may be unaware of or underestimate the impact of cell phone use on their own driving performance. Problems associated with distracted driving are not limited to novice or teenage drivers; multifaceted universal prevention efforts aimed at impacting large segments of the population may have the greatest impact. Legislation limiting drivers' cell phone use has had little impact, possibly due to low regulation and enforcement. Behaviour change programmes, improved vehicle safety, and public awareness campaigns have been developed as potential preventive efforts to reduce accidents caused by distracted drivers.

    Full Text Available AIMS - The aims were to compare past-year at-risk and problem gambling (ARPG and other at-risk behaviours (computer gaming, risky alcohol consumption, tobacco smoking by age and gender, and to explore how ARPG is associated with risky alcohol consumption, tobacco smoking, poor mental health and loneliness in males and females. DESIGN - Data from respondents aged 15-28 (n = 822 were derived from a cross-sectional random sample of population-based data (n = 4484. The data were collected in 2011-2012 by telephone interviews. The Problem Gambling Severity Index (PGSI, score≥2 was used to evaluate ARPG. Prevalence rates for risk behaviours were compared for within gender-specific age groups. Regression models were gender-specific. RESULTS - The proportion of at-risk and problem gamblers was higher among males than females in all age groups except among 18-21-year-olds, while frequent computer gaming was higher among males in all age groups. The odds ratio (95% CI of being a male ARPGer was 2.57 (1.40-4.74 for risky alcohol consumption; 1.95 (1.07-3.56 for tobacco smoking; 2.63 (0.96-7.26 for poor mental health; and 4.41 (1.20-16.23 for feeling lonely. Likewise, the odds ratio (95% CI of being a female ARPGer was 1.19 (0.45-3.12 for risky alcohol consumption; 4.01 (1.43-11.24 for tobacco smoking; 0.99 (0.18-5.39 for poor mental health; and 6.46 (1.42-29.34 for feeling lonely. All 95% CIs of ARPG correlates overlapped among males and females. CONCLUSIONS - Overall, past-year at-risk and problem gambling and computer gaming seem to be more common among males than females; however, for risky alcohol consumption similar gender differences were evident only for the older half of the sample. No clear gender differences were seen in correlates associated with ARPG.

    The present study examined the predictive utility of constructs specified by the theory of planned behaviour (TPB) and prototype willingness model (PWM) for young and older male drivers' willingness to drive while intoxicated. A cross-sectional questionnaire was employed. Two hundred male drivers, recruited via a street survey, voluntarily completed measures of attitude, subjective norm, perceived behavioural control, prototype perceptions, and willingness. Findings showed that the TPB and PWM variables explained 65% of the variance in young male drivers' willingness and 47% of the variance in older male drivers' willingness, with the interaction between prototype favourability and similarity contributing 7% to the variance explained in older males' willingness to drive while intoxicated. The findings possess implications for theory, research, and anti-drink driving campaigns. ©2010 The British Psychological Society.

    Full Text Available Road safety is a substantial issue worldwide. Speeding contributed to one-third of all the fatal crashes reported from year 2002 to 2011 with young drivers reported to have the highest fatality and injury rates. This paper studied on the speeding driving behavior of 10 teenagers and 10 adults, from both genders. The aim was to investigate the relationship between age and gender with speeding driving behavior. The drivers were required to drive within an enclosed compound by using a test car. Results showed young and male drivers averagely travelled at higher velocity before entering the roundabout and at the same time accelerate to higher velocity upon exiting the roundabout compared to old and female drivers.

    Issue addressed The fly-in, fly-out (FIFO) and drive-in, drive-out (DIDO) models of mining in Australia have led to concerns about adverse health and psychosocial impacts. Despite speculation that increased levels of sexually transmitted infections (STIs) in Australia, including HIV, are associated with FIFO/DIDO work, we know little about sexual risk-taking behaviours in mining populations. This study explores differences in sexual risk taking and perceptions of risk between FIFO/DIDO miners and residential miners. Methods A cross-sectional survey was administered to a sample (n=444) of male miners working in Queensland, Australia. The self-completed survey contained 49 questions relating to knowledge, attitudes and behaviour and included demographic information and specific items related to sex and relationships. Results FIFO/DIDO status was not associated with any differential sexual risk-taking behaviours, except for an increased probability of reporting 'ever being diagnosed with an STI'; 10.8% of FIFO/DIDO respondents versus 3.6% of others (x(2) (1)=4.43, P=0.35). Conclusions Our results appear to counter anecdotal evidence that FIFO/DIDO miners engage in higher sexual risk behaviours when compared with residential miners. So what? Anecdotal evidence linking the rise of sexually transmitted infections with the FIFO/DIDO mining workforce could drive costly and unnecessary approaches to prevention. Further research, surveillance and monitoring are required to inform health promotion interventions.

    Full Text Available Abstract Background Many countries have adopted health policies that are targeted at reducing the risk factors for chronic non-communicable diseases. These policies promote a healthy population by encouraging people to adopt healthy lifestyle behaviours. This paper examines healthy lifestyle behaviour among Ghanaian adults by comparing behaviours before and after the introduction of a national health policy. The paper also explores the socio-economic and demographic factors associated with healthy lifestyle behaviour. Method Descriptive, bivariate and multivariate regression techniques were employed on two nationally representative surveys (2003 World Health Survey (Ghana and 2008 Ghana Demographic and Health Survey to arrive at the results. Results While the prevalence of some negative lifestyle behaviours like smoking has reduced others like alcohol consumption has increased. Relatively fewer people adhered to consuming the recommended amount of fruit and vegetable servings per day in 2008 compared to 2003. While more females (7.0% exhibited healthier lifestyles, more males (9.0% exhibited risky lifestyle behaviours after the introduction of the policy. Conclusion The improvement in healthy lifestyle behaviours among female adult Ghanaians will help promote healthy living and potentially lead to a reduction in the prevalence of obesity among Ghanaian women. The increase in risky lifestyle behaviour among adult male Ghanaians even after the introduction of the health policy could lead to an increase in the risk of non-communicable diseases among men and the resultant burden of disease on them and their families will push more people into poverty.

    Teen drivers' over-involvement in crashes has been attributed to a variety of factors, including distracted driving. With the rapid development of in-vehicle systems and portable electronic devices, the burden associated with distracted driving is expected to increase. The current study identifies predictors of secondary task engagement among teenage drivers and provides basis for interventions to reduce distracted driving behavior. We described the prevalence of secondary tasks by type and driving conditions and evaluated the associations between the prevalence of secondary task engagement, driving conditions, and selected psychosocial factors. The private vehicles of 83 newly-licensed teenage drivers were equipped with Data Acquisition Systems (DAS), which documented driving performance measures, including secondary task engagement and driving environment characteristics. Surveys administered at licensure provided psychosocial measures. Overall, teens engaged in a potentially distracting secondary task in 58% of sampled road clips. The most prevalent types of secondary tasks were interaction with a passenger, talking/singing (no passenger), external distraction, and texting/dialing the cell phone. Secondary task engagement was more prevalent among those with primary vehicle access and when driving alone. Social norms, friends' risky driving behaviors, and parental limitations were significantly associated with secondary task prevalence. In contrast, environmental attributes, including lighting and road surface conditions, were not associated with teens' engagement in secondary tasks. Our findings indicated that teens engaged in secondary tasks frequently and poorly regulate their driving behavior relative to environmental conditions. Practical applications: Peer and parent influences on secondary task engagement provide valuable objectives for countermeasures to reduce distracted driving among teenage drivers.

    To examine, among adolescents and emerging adults attending inner-city lower education, associations between risky music-listening behaviors (from MP3 players and in discotheques and at pop concerts) and more traditional health-risk behaviors: substance use (cigarettes, alcohol, cannabis, and hard drugs) and unsafe sexual intercourse. A total of 944 students in Dutch inner-city senior-secondary vocational schools completed questionnaires about their music-listening and traditional health-risk behaviors. Multiple logistic regression analyses were used to examine associations between music-listening and traditional health-risk behaviors. Risky MP3-player listeners used cannabis more often during the past 4 weeks. Students exposed to risky sound levels during discotheque and pop concert attendance used cannabis less often during the past 4 weeks, were more often binge drinkers, and reported inconsistent condom use during sexual intercourse. The coexistence of risky music-listening behaviors with other health-risk behaviors provides evidence in support of the integration of risky music-listening behaviors within research on and programs aimed at reducing more traditional health-risk behaviors, such as substance abuse and unsafe sexual intercourse.

    Some people love taking risks, while others avoid gambles at all costs. The neural mechanisms underlying individual variation in preference for risky or certain outcomes, however, remain poorly understood. Although behavioral pathologies associated with compulsive gambling, addiction and other psychiatric disorders implicate deficient serotonin signaling in pathological decision making, there is little experimental evidence demonstrating a link between serotonin and risky decision making, in part due to the lack of a good animal model. We used dietary rapid tryptophan depletion (RTD) to acutely lower brain serotonin in three macaques performing a simple gambling task for fluid rewards. To confirm the efficacy of RTD experiments, we measured total plasma tryptophan using high-performance liquid chromatography (HPLC) with electrochemical detection. Reducing brain serotonin synthesis decreased preference for the safe option in a gambling task. Moreover, lowering brain serotonin function significantly decreased the premium required for monkeys to switch their preference to the risky option, suggesting that diminished serotonin signaling enhances the relative subjective value of the risky option. These results implicate serotonin in risk-sensitive decision making and, further, suggest pharmacological therapies for treating pathological risk preferences in disorders such as problem gambling and addiction.

    Men who have sex with men (MSM) experience significant inequalities in health and well-being. They are the group in the UK at the highest risk of acquiring a human immunodeficiency virus (HIV) infection. Guidance relating to both HIV infection prevention, in general, and individual-level behaviour change interventions, in particular, is very limited. To conduct an evidence synthesis of the clinical effectiveness of behaviour change interventions to reduce risky sexual behaviour among MSM after a negative HIV infection test. To identify effective components within interventions in reducing HIV risk-related behaviours and develop a candidate intervention. To host expert events addressing the implementation and optimisation of a candidate intervention. All major electronic databases (British Education Index, BioMed Central, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Educational Resource Index and Abstracts, Health and Medical Complete, MEDLINE, PsycARTICLES, PsycINFO, PubMed and Social Science Citation Index) were searched between January 2000 and December 2014. A systematic review of the clinical effectiveness of individual behaviour change interventions was conducted. Interventions were examined using the behaviour change technique (BCT) taxonomy, theory coding assessment, mode of delivery and proximity to HIV infection testing. Data were summarised in narrative review and, when appropriate, meta-analysis was carried out. Supplemental analyses for the development of the candidate intervention focused on post hoc realist review method, the assessment of the sequential delivery and content of intervention components, and the social and historical context of primary studies. Expert panels reviewed the candidate intervention for issues of implementation and optimisation. Overall, trials included in this review ( n  = 10) demonstrated that individual-level behaviour change interventions are effective in reducing key HIV infection risk

    Secondary task engagement such as cell phone use while driving is a common behavior among adolescents and emerging adults. Texting and other distracting cell phone use in this population contributes to the high rate of fatal car crashes. Peer engagement in similar risky driving behaviors, such as texting, could socially influence driver phone use behavior. The present study investigates the prospective association between peer and emerging adult texting while driving the first year after high school. Surveys were conducted with a national sample of emerging adults and their nominated peers. Binomial logistic regression analyses, adjusting for gender, race/ethnicity, parental education, and family affluence, showed that participants (n=212) with peers (n=675) who reported frequently texting while driving, were significantly more likely to text while driving the following year (odds ratio, 3.01; 95% CI, 1.19-7.59; P=0.05). The findings are consistent with the idea that peer texting behavior influences the prevalence of texting while driving among emerging adults. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Since the inception of the Internet there has been immense growth in the number of internet users worldwide, and the integration of social media in our daily lives has become commonplace for many. Yet, alongside the many benefits of this global connectivity come numerous risks. Research shows that individuals of all ages are exposed to, and engage in, risky activities online, despite numerous campaigns to highlight the perils of risky online behaviour. Although the rates of victimisation incr...

    The link between risk-taking behavior in various aspects of life has long been an area of debate among economists and psychologists. Using an extensive data set from Denmark, this study provides an empirical investigation of the link between risky driving and risk taking in other aspects of life...... results in this study suggest that risk-taking behavior in various aspects of life can be associated, and our results corroborate previous evidence on the link between individuals’ risk preferences across various aspects of life. This implies that individuals’ driving behavior, which is commonly...

    Usage-Based Insurances (UBI) enable policyholders to actively reduce the impact of vehicle insurance costs by adopting a safer and more eco-friendly driving style. UBI is especially relevant for younger drivers, who are a high-risk population. The effectiveness of UBI should be enhanced by providing in-car feedback optimised for individual drivers. Thirty young novice drivers were therefore invited to complete six experimental drives with an in-car interface that provided real-time information on rewards gained, their driving behaviour and the speed limit. Reward size was either displayed directly in euro, indirectly as a relatively large amount of credits, or as a percentage of the maximum available bonus. Also, interfaces were investigated that provided partial information to reduce the potential for driver distraction. Compared to a control no-UBI condition, behaviour improved similarly across interfaces, suggesting that interface personalisation after an initial familiarisation period could be feasible without compromising feedback effectiveness. Practitioner Summary: User experiences and effects on driving behaviour of six in-car interfaces were compared. The interface provided information on driving behaviour and rewards in a UBI setting. Results suggest that some personalisation of interfaces may be an option after an initial familiarisation period as driving behaviour improved similarly across interfaces.

    The National Highway Traffic Safety Administration suggests that given the changing demographics of the United States it is important to examine motor vehicle statistics by race and ethnicity. The current study sought to explore differences in traffic safety concerns and driving behaviors between black and white drivers. An annual, anonymous, random-digit-dial telephone survey was used to collect data between 2003 and 2009 from Maryland drivers. Drivers (N = 5503) were assessed regarding their driving behaviors and perceived risk of receiving a traffic violation. Results showed that black drivers perceived a greater likelihood of being stopped for driving under the influence (DUI), for not wearing a seat belt and for speeding than white drivers. These differences were found among drivers with or without a history of being ticketed. Black drivers were also more likely to report a variety of risky driving behaviors than white drivers. However, black drivers were not more likely to report receiving a ticket or citation in the last month after controlling for demographic factors, risky driving behaviors, and geographic region of the state, where traffic enforcement may vary. Findings indicate that black drivers are not more likely to be ticketed, despite perceptual biases that may exist among some drivers. These differences appear to be explained by demographic as well as regional factors. These results highlight the need for more research to understand the potential differences in driving behaviors between racial and ethnic groups. More research is also needed to develop countermeasures for racial and ethnic groups most at risk for motor vehicle violations and crashes.

    Youth are engaging in multiple risky behaviours, increasing their risk of overweight, obesity, and related chronic diseases. The objective of this study was to examine the effect of engaging in unique clusters of unhealthy behaviours on youths' body mass index (BMI) trajectories. This study used a linked-longitudinal sample of Grades 9 and 10 students (13 to 17 years of age) participating in the COMPASS host study. Students reported obesity-related and other risky behaviours at baseline and height and weight (to derive BMI) at baseline (2012/2013) and annually for 2 years post-baseline (2013/14 and 2014/15). Students were grouped into behavioural clusters based on response probabilities. Linear mixed effects models, using BMI as a continuous outcome measure, were used to examine the effect of engaging in clusters of risky behaviours on BMI trajectories. There were significant differences in BMI of the four behavioural clusters at baseline that remained consistent over time. Higher BMI values were found among youth classified at baseline to be Typical High School Athletes (β = 0.232 kg/m2, [confidence interval (CI): 0.03-0.50]), Inactive High Screen-User (β = 0.348 kg/m2, CI: 0.11-0.59) and Moderately Active Substance Users (β = 0.759 kg/m2, CI: 0.36-1.15) compared to students classified as Health Conscious. Despite these baseline differences, BMI appeared to increase across all behavioural clusters annually by the same amount (β = 0.6097 kg/m2, (CI) = 0.57-0.64). Although annual increases in BMI did not differ by behavioural clusters, membership in a particular behavioural cluster was associated with baseline BMI, and these differences remained consistent over time. Results indicate that intervening and modifying unhealthy behaviours earlier might have a greater impact than during adolescence. Health promotion strategies targeting the highest risk youth as they enter secondary school might be promising means to prevent or delay the onset of obesity.

    A questionnaire survey was carried out among 1041 students in secondary schools and colleges in Dar-es-Salaam, Tanzania to evaluate the relationship between HIV-risky sexual behaviour and anti-condom bias, as well as with AIDS-related information, knowledge, perceptions and attitudes. Self-reportedly, 54% of students (75% of the boys and 40% of the girls) were sexually active, 39% had a regular sexual partner and 13% had multiple partners in the previous year. The condom use rate was higher than previous reports. However, 30% of sexually active respondents did not always use condoms (Risk-1 behaviour) and 35% of those with multiple partners in the previous year did not always use condoms (Risk-2 behaviour). Multiple logistic regression analyses indicated that 'sex partner hates condom' had association with both Risk-1 behaviour (OR 2.47; 95% CI 1.58-3.85) and Risk-2 behaviour (OR 2.47; 95% CI 1.10-5.48). 'Use of condom prevents HIV infection' also had association with both Risk-1 behaviour (OR 2.09; 95% CI 1.19-3.67) and Risk-2 behaviour (OR 3.73; 95% CI 1.28-11.03). Students engaging in risky behaviour were aware of the risk, even though they failed to change their behaviour. Reasons for the AIDS epidemic among Tanzanian students and the importance of more effective AIDS education are also discussed.

    The ability to make advantageous decisions under circumstances in which there is a risk of adverse consequences is an important component of adaptive behavior; however, extremes in risk taking (either high or low) can be maladaptive and are characteristic of a number of neuropsychiatric disorders. To better understand the contributions of various affective and cognitive factors to risky decision making, cohorts of male Long-Evans rats were trained in a "Risky Decision making Task" (RDT), in which they made discrete trial choices between a small, "safe" food reward and a large, "risky" food reward accompanied by varying probabilities of footshock. Experiment 1 evaluated the relative contributions of the affective stimuli (i.e., punishment vs. reward) to RDT performance by parametrically varying the magnitudes of the footshock and large reward. Varying the shock magnitude had a significant impact on choice of the large, "risky" reward, such that greater magnitudes were associated with reduced choice of the large reward. In contrast, varying the large, "risky" reward magnitude had minimal influence on reward choice. Experiment 2 compared individual variability in RDT performance with performance in an attentional set shifting task (assessing cognitive flexibility), a delayed response task (assessing working memory), and a delay discounting task (assessing impulsive choice). Rats characterized as risk averse in the RDT made more perseverative errors on the set shifting task than did their risk taking counterparts, whereas RDT performance was not related to working memory abilities or impulsive choice. In addition, rats that showed greater delay discounting (greater impulsive choice) showed corresponding poorer performance in the working memory task. Together, these results suggest that reward-related decision making under risk of punishment is more strongly influenced by the punishment than by the reward, and that risky and impulsive decision making are associated with

    New genetic technologies promise to generate valuable insights into the aetiology of several psychiatric conditions, as well as a wider range of human and animal behaviours. Advances in the neurosciences and the application of new brain imaging techniques offer a way of integrating DNA analysis with studies that are looking at other biological markers of behaviour. While candidate 'genes for' certain conditions, including schizophrenia and bipolar disorders, are said to be 'un-discovered' at a faster rate than they are discovered, many studies are being conducted on personality traits such as aggressiveness and anti-social traits. The clinical applicability and implications of these studies are often discussed within the scientific community. However, little attention has so far been paid to their possible policy implications in relation to criminality management and to Criminal Law itself. Similarly, the related ethical issues arising in the field of crime control, and the tensions between enhancing security for society and protecting civil liberties, are currently under-explored. This paper investigates these ethical issues by focusing on the views of those professionals - including judges, lawyers, probation officers and social workers - who work with individuals 'deemed at risk' of violent and aggressive behaviours. It also discusses and problematizes mainstream rhetoric and arguments around the notion of 'risky individuals'.

    People with moderate central vision loss are legally permitted to drive with a bioptic telescope in 39 US states and the Netherlands, but the safety of bioptic driving remains highly controversial. There is no scientific evidence about bioptic use and its impact on safety. We propose searching for evidence by recording naturalistic driving activities in patients' cars. In a pilot study we used an analogue video system to record two bioptic drivers' daily driving activities for 10 and 5 days, respectively. In this technical report, we also describe our novel digital system that collects vehicle manoeuvre information and enables recording over more extended periods, and discuss our approach to analyzing the vast amount of data. Our observations of telescope use by the pilot subjects were quite different from their reports in a previous survey. One subject used the telescope only seven times in nearly 6 h of driving. For the other subject, the average interval between telescope use was about 2 min, and Mobile (cell) phone use in one trip extended the interval to almost 5 min. We demonstrate that computerized analysis of lengthy recordings based on video, GPS, acceleration, and black box data can be used to select informative segments for efficient off-line review of naturalistic driving behaviours. The inconsistency between self reports and objective data as well as infrequent telescope use underscores the importance of recording bioptic driving behaviours in naturalistic conditions over extended periods. We argue that the new recording system is important for understanding bioptic use behaviours and bioptic driving safety. © 2011 The College of Optometrists.

  5. Dissecting the risky-choice framing effect

    Full Text Available Using five variants of the Asian Disease Problem, we dissected the risky-choice framing effect by requiring each participant to provide preference ratings for the full decision problem and also to provide attractiveness ratings for each of the component parts, i.e., the sure-thing option and the risky option. Consistent with previous research, more risky choices were made by respondents receiving negatively framed versions of the decision problems than by those receiving positively framed versions. However, different processes were evident for those scoring high and low on numeracy. Whereas the choices of the less numerate showed a large effect of frame above and beyond any influence of their evaluations of the separate options, the choices of the highly numerate were almost completely accounted for by their attractiveness ratings of the separate options. These results are consistent with an increased tendency of the highly numerate to integrate complex numeric information in the construction of their preferences and a tendency for the less numerate to respond more superficially to non-numeric sources of information.

    Full Text Available Abstract Background Knowledge about the prevalence of sexual risk behaviour (SRB in adolescence is needed to prevent unwanted health consequences. Studies on SRB among adolescents in Central Europe are rare and mostly rely on a single indicator for SRB. This study aims to assess the association of behavioural and psychological factors with three types of SRB in adolescents in Central Europe. Methods We obtained data on behavioural factors (having been drunk during previous month, smoking during previous week, early sexual initiation, psychological factors (self-esteem, well-being, extroversion, neuroticism, religiousness, and SRB (intercourse under risky conditions, multiple sexual partners, and inconsistent condom use in 832 Slovak university students (response 94.3%. Results Among those with sexual experience (62%, inconsistent condom use was the most prevalent risk behaviour (81% in females, 72% in males. With the exception of having been drunk in males, no factor was associated with inconsistent condom use. Regarding the other types of SRB, early sexual initiation was most strongly associated. In addition, other, mostly behavioural, factors were associated, in particular having been drunk. Conclusion Results suggest that behavioural factors are more closely related to SRB than psychological factors. Associations differ by type of SRB and gender but offer few clues to target risk groups for inconsistent condom use. Results show a high need for health-promotion programmes in early adolescence that target SRB in conjunction with other health risk behaviours such as alcohol abuse.

    This paper investigates the relationship between personality traits and health behaviours in adolescence using a large and recent cohort study. In particular, we investigate the impact of locus of control, self-esteem and work ethics at ages 15-16 years on the incidence of health behaviours such as alcohol consumption, cannabis and other drug use, unprotected and early sexual activity and sports and physical activity. We use matching methods to control for a very rich set of adolescent and family characteristics, and we find that personality traits do affect health behaviours. In particular, individuals with external locus of control, low self-esteem or with low levels of work ethics seem more likely in engage in risky health behaviours.

    To identify the characteristics of current drinker and risky alcohol-drinking pattern by profiles in Malaysia. We analyzed data from the National Health and Morbidity Survey 2011. It was a cross-sectional population-based with two stages stratified random sampling design. A validated Alcohol Use Disorder Identification Test Malay questionnaire was used to assess the alcohol consumption and its alcohol related harms. Analysis of complex survey data using Stata Version 12 was done for descriptive analysis on alcohol use and risky drinking by socio-demography profiles. Logistic regression analysis was used to measure the association of risky drinking status with the socio-demography characteristics. The prevalence of current alcohol use was 11.6% [95% confidence interval (CI): 10.5, 12.7], among them 23.6% (95% CI: 21.0, 26.4) practiced risky drinking. The onset for alcohol drinking was 21 years old (standard deviation 7.44) and majority preferred Beer. Males significantly consumed more alcohol and practiced risky drinking. Current alcohol use was more prevalent among urbanites, Chinese, those with high household income, and high education. Conversely, risky drinking was more prevalent among rural drinkers, Bumiputera Sabah and Sarawak, low education and low household income. The estimated odds of risky drinking increased by a factor of 3.5 among Males while a factor of 2.7 among Bumiputera Sabah and Sarawak. Education status and household income was not a significant predictor to risky drinking. There was an inverse drinking pattern between current drinker and risky drinking by the socio-demography profiles. Initiating early screening and focused intervention might avert further alcohol related harms and dependence among the risky drinkers. © The Author 2014.

    We examined whether exposure to high-performing schools reduces the rates of risky health behaviors among low-income minority adolescents and whether this is due to better academic performance, peer influence, or other factors. By using a natural experimental study design, we used the random admissions lottery into high-performing public charter high schools in low-income Los Angeles neighborhoods to determine whether exposure to successful school environments leads to fewer risky (eg, alcohol, tobacco, drug use, unprotected sex) and very risky health behaviors (e.g., binge drinking, substance use at school, risky sex, gang participation). We surveyed 521 ninth- through twelfth-grade students who were offered admission through a random lottery (intervention group) and 409 students who were not offered admission (control group) about their health behaviors and obtained their state-standardized test scores. The intervention and control groups had similar demographic characteristics and eighth-grade test scores. Being offered admission to a high-performing school (intervention effect) led to improved math (P performance of public schools in low-income communities may be a powerful mechanism to decrease very risky health behaviors among low-income adolescents and to decrease health disparities across the life span.

    This study sought to investigate the relationship between cell phone conversation type and dangerous driving behaviors. It was hypothesized that more emotional phone conversations engaged in while driving would produce greater frequencies of dangerous driving behaviors in a simulated environment than more mundane conversation or no phone conversation at all. Participants were semi-randomly assigned to one of three conditions: (1) no call, (2) mundane call, and, (3) emotional call. While driving in a simulated environment, participants in the experimental groups received a phone call from a research confederate who either engaged them in innocuous conversation (mundane call) or arguing the opposite position of a deeply held belief of the participant (emotional call). Participants in the no call and mundane call groups differed significantly only on percent time spent speeding and center line crossings, though the mundane call group consistently engaged in more of all dangerous driving behaviors than did the no call participants. Participants in the emotional call group engaged in significantly more dangerous driving behaviors than participants in both the no call and mundane call groups, with the exception of traffic light infractions, where there were no significant group differences. Though there is need for replication, the authors concluded that whereas talking on a cell phone while driving is risky to begin with, having emotionally intense conversations is considerably more dangerous.

  11. Decision Making under Risk Condition in Patients with Parkinson’s Disease: A Behavioural and fMRI Study

    Kirsten Labudda

    2010-01-01

    Full Text Available We aimed to study whether previously described impairment in decision making under risky conditions in patients with Parkinson's disease (PD is affected by deficits in using information about potential incentives or by processing feedback (in terms of fictitious gains and losses following each decision. Additionally, we studied whether the neural correlates of using explicit information in decision making under risk differ between PD patients and healthy subjects. We investigated ten cognitively intact PD patients and twelve healthy subjects with the Game of Dice Task (GDT to assess risky decision making, and with an fMRI paradigm to analyse the neural correlates of information integration in the deliberative decision phase. Behaviourally, PD patients showed selective impairment in the GDT but not on the fMRI task that did not include a feedback component. Healthy subjects exhibited lateral prefrontal, anterior cingulate and parietal activations when integrating decision-relevant information. Despite similar behavioural patterns on the fMRI task, patients exhibited reduced parietal activation. Behavioural results suggest that PD patients’ deficits in risky decision making are dominated by impaired feedback utilization not compensable by intact cognitive functions. Our fMRI results suggest similarities but also differences in neural correlates when using explicit information for the decision process, potentially indicating different strategy application even if the interfering feedback component is excluded.

    2005-01-01

    We reviewed literature on cognitive, sensory, motor and physical factors associated with safe driving and crash risk in older adults with the goal of developing a model of factors enabling safe driving behaviour. Thirteen empirical studies reporting associations between cognitive, sensory, motor and physical factors and either self-reported crashes, state crash records or on-road driving measures were identified. Measures of attention, reaction time, memory, executive function, mental status, visual function, and physical function variables were associated with driving outcome measures. Self-monitoring was also identified as a factor that may moderate observed effects by influencing driving behavior. We propose that three enabling factors (cognition, sensory function and physical function/medical conditions) predict driving ability, but that accurate self-monitoring of these enabling factors is required for safe driving behaviour.

  13. Environmental determinants of celeration behaviour.

    2015-01-01

    Celeration (speed change) behaviour of drivers has been posited to be the best predictor of their traffic accident involvement. The origins of this behaviour, however, have not been specified. A model is therefore introduced, where celeration is partly due to the individual disposition of the driver (i.e., driving style), and partly to the environment (road layout, rules and traffic density). Three measurement problems for celeration were studied; the effect of traffic density, of regular versus irregular routes, and weight of the vehicle (loaded/unloaded) on celeration behaviour. Two small samples of truck drivers in Sweden were measured for several months each. There was a strong effect of vehicle load, with behaviour being more cautious with increased weight. Driving on different roads also yielded differences in behaviour, although the design used did not permit conclusions about what caused these. Traffic volume was not found to have any reliable effect on celeration.

    During the summer of 1977, the speeds of 5742 motor vehicles were registered in the Katschbergtunnel. On the basis of the average speed, the frequency distribution of the speed increases and decreases of the individual vehicles between the loops, the reference distance, the reference time and the average maximum speed difference in the tunnel, a tunnel cycle was elaborated, reproducing the representative driving behaviour of the individual vehicle in the Katschbergtunnel. The tunnel cycle shows a driving behaviour with speeds fluctuating around the average speed of 74 km/h (46 m.p.h.) and corresponds to a steady traffic flow. The CO-emission during constant driving at 74 km/h (46 m.p.h.) and the CO-emission in the tunnel cycle were measured during test drives with eight test vehicles on the dynamometer of the Institute for Internal Combustion Engines and Automotive Engineering (Institut fuer Verbrennungskraftmaschinen und Kraftfahrwesen) of the Technical University Vienna.

    2018-03-01

    Full Text Available Analyzing naturalistic driving behavior recorded with in-car cameras is an ecologically valid method for measuring driving errors, but it is time intensive and not easily applied on a large scale. This study validated a semi-automated, computerized method using archival naturalistic driving data collected for drivers with mild Alzheimer’s disease (AD; n = 44 and age-matched healthy controls (HC; n = 16. The computerized method flagged driving situations where safety concerns are most likely to occur (i.e., rapid stops, lane deviations, turns, and intersections. These driving epochs were manually reviewed and rated for error type and severity, if present. Ratings were made with a standardized scoring system adapted from DriveCam®. The top eight error types were applied as features to train a logistic model tree classifier to predict diagnostic group. The sensitivity and specificity were compared among the event-based method, on-road test, and composite ratings of two weeks of recorded driving. The logistic model derived from the event-based method had the best overall accuracy (91.7% and sensitivity (97.7% and high specificity (75.0% compared to the other methods. Review of driving situations where risk is highest appears to be a sensitive data reduction method for detecting cognitive impairment associated driving behaviors and may be a more cost-effective method for analyzing large volumes of naturalistic data.

  18. A framework for safer driving in Mauritius

    2017-12-01

    Full Text Available According to the National Transport Authority (NTA, there were 493,081 registered vehicles in Mauritius in April 2016, which represents a 1.4% annual increase compared to 2015. Despite the sensitization campaigns and the series of measures setup by the Minister of Public Infrastructure and Land Transport, the number of road accidents continues to rise. The three main elements that contribute to accidents are: road infrastructure, vehicle and driver. The driver has the highest contribution in collisions. If the driver is given the right information (e.g. driving behaviour, accident-prone areas and vehicle status at the right time, he/she can make better driving decisions and react promptly to critical situations. This paper proposes a framework for safer driving in Mauritius that uses an on-board car diagnostic module (OBDII to collect data such as vehicle average speed, engine revolution and acceleration. This module relays the data to a cloud environment where an adaptive algorithm analyses the data and predicts driver behaviour in real-time. Based on driving behaviour, mobile alerts can be sent to the driver in the form of messages, voice commands or beeps. A survey was also carried out to evaluate the acceptance rate of such a framework by people of different age groups in Mauritius.

    Despite being identified as an unsafe (and, in some jurisdictions, illegal) driving practice, the psychological factors underlying people's decision to use their mobile phone while driving have received little attention. The present study utilised the theory of planned behaviour (TPB) to examine the role of attitudes, norms, control factors, and risk perceptions, in predicting people's intentions to use their mobile phone while driving. We examined the predictors of intentions to use a mobile phone while driving in general, and for calling and text messaging in 4 scenarios differing in descriptions of vehicle speed and time pressure. There was some support for the TPB given that attitudes consistently predicted intentions to drive while using a mobile phone and that pressure from significant others (norms) determined some phone use while driving intentions, although less support was found for the role of perceptions of control. Risk was not generally predictive of safer driving intentions. These findings indicate that different factors influence each form of mobile phone use while driving and, hence, a multi-strategy approach is likely to be required to address the issue.

    Sexual activity online may result in positive experiences for young people, or lead them to engage in risky behaviours possibly resulting in sexual assault or abuse. The aim of our study was to investigate associations between online sexual behaviours among Swedish youth and background factors as well as aspects of well-being. The behaviours investigated were: having sex online with a contact met online, having sex with an online contact offline, posting sexual pictures online, and selling sex online. We used data from a representative sample of 3,432 Swedish youth who were asked about their lifetime experiences as well as their experiences within the previous year. We hypothesized that more advanced online sexual behaviours were associated with more problematic background factors, worse psychosocial well-being and riskier behaviours in general. Bivariate relationships were evaluated followed by a multiple logistic regression model. Our data suggested that most Swedish youth do not perform any of the assessed online sexual behaviours. Young people who reported online sexual behaviour showed a more problematic background, rated their health as poorer, had a more sexualized life and had experienced more sexual or physical abuse. Professionals who work with young people need to help them better evaluate potential risks online and offer support when needed. Youths who sell sex online are especially at risk and need extra attention, as they might be in greater need of protection and therapeutic support.

    Adolescence is a period characterized by increased sensitivity to social cues, as well as increased risk-taking in the presence of peers. For example, automobile crashes are the leading cause of death for adolescents, and driving with peers increases the risk of a fatal crash. Growing evidence points to an interaction between neural systems implicated in cognitive control and social and emotional context in predicting adolescent risk. We tested such a relationship in recently licensed teen drivers. Participants completed an fMRI session in which neural activity was measured during a response inhibition task, followed by a separate driving simulator session 1 week later. Participants drove alone and with a peer who was randomly assigned to express risk-promoting or risk-averse social norms. The experimentally manipulated social context during the simulated drive moderated the relationship between individual differences in neural activity in the hypothesized cognitive control network (right inferior frontal gyrus, BG) and risk-taking in the driving context a week later. Increased activity in the response inhibition network was not associated with risk-taking in the presence of a risky peer but was significantly predictive of safer driving in the presence of a cautious peer, above and beyond self-reported susceptibility to peer pressure. Individual differences in recruitment of the response inhibition network may allow those with stronger inhibitory control to override risky tendencies when in the presence of cautious peers. This relationship between social context and individual differences in brain function expands our understanding of neural systems involved in top-down cognitive control during adolescent development.

    Full Text Available The main research problem is focused on the following question: Is it possible to identify specific patterns of interaction between precipitating and protective factors for the risky behavior among adolescents. The research was conducted on the sample of 204 adolescents of both genders (18 to 20 years old. Specific personality traits and socio-demographic characteristics are manifested as the most important precipitating and/or protective factors for the risky behavior. The frame of reference for personality assessment was the alternative five-factor model (Zuckerman, 2002, specified in the ZKPQ-50-CC questionnaire, and consisted of the five biologically determined personality traits: activity, aggressiveness/hostility, impulsive sensation seeking, neuroticism/anxiety and sociability. Latent dimensions of the risky behavior: risky activities and life - conditions, were extracted by applying the homogeneity analyses (HOMALS. The matrix of squared Euclidean distances (in the common space of factor scores on the principal components of ZKPQ questionnaire, scores on HOMALS dimensions and school grades was a subject of the Ward hierarchical cluster analysis method, extracting three clusters. According to the discriminant functions: risk proneness and pro-social activity, the clusters were identified: the group of pro-social oriented adolescents, the aloof group and the group of adolescents prone to risky behavior. The results have considerable implications for the prevention programs’ development and implementation.

    A range of species exploit anthropogenic food resources in behaviour known as 'raiding'. Such behavioural flexibility is considered a central component of a species' ability to cope with human-induced environmental changes. Here, we study the behavioural processes by which raiding male chacma baboons (Papio ursinus) exploit the opportunities and mitigate the risks presented by raiding in the suburbs of Cape Town, South Africa. Ecological sampling and interviews conducted with 'rangers' (employed to manage the baboons' space use) revealed that baboons are at risk of being herded out of urban spaces that contain high-energy anthropogenic food sources. Baboon-attached motion/GPS tracking collars showed that raiding male baboons spent almost all of their time at the urban edge, engaging in short, high-activity forays into the urban space. Moreover, activity levels were increased where the likelihood of deterrence by rangers was greater. Overall, these raiding baboons display a time-activity balance that is drastically altered in comparison to individuals living in more remote regions. We suggest our methods can be used to obtain precise estimates of management impact for this and other species in conflict with people.

    Parasites are ubiquitous components of the environment that contribute to behavioural and life-history variation among hosts. Although it is well known that host behaviour can affect parasite infection risk and that parasites can alter host behaviour, the potential for dynamic feedback between these processes is poorly characterized. Using Grant's gazelle (Nanger granti) as a model, we tested for reciprocal effects of behaviour on parasites and parasites on behaviour to understand whether behaviour-parasite feedback could play a role in maintaining variation in male reproductive behaviour. Adult male gazelles either defend territories to attract mates or reside in bachelor groups. Territoriality is highly variable both within- and between-individuals, suggesting that territory maintenance is costly. Using a combination of longitudinal and experimental studies, we found that individual males transition frequently between territorial and bachelor reproductive status, and that elevated parasite burdens are a cost of territoriality. Moreover, among territorial males, parasites suppress aspects of behaviour related to territory maintenance and defence. These results suggest that territorial behaviour promotes the accumulation of parasites in males, and these parasites dampen the very behaviours required for territory maintenance. Our findings suggest that reciprocal feedback between host behaviour and parasitism could be a mechanism maintaining variation in male reproductive behaviour in the system. © 2016 The Author(s).

    Highlights: • Rhombic drive and crank drive mechanisms of a beta type engine were compared. • Nodal analysis method was used to compare engines having different drive mechanism. • Maximum specific power was 1410 W/L for rhombic-drive engine. • Heat transfer coefficient was determined as 475 W/m"2K for rhombic-drive engine. • Rhombic drive provided higher efficiency because of its better kinematic behaviours. - Abstract: In this study, the effect of rhombic drive and crank drive mechanisms on the performance of a beta-type Stirling engine was investigated by nodal analysis. Kinematic and thermodynamic relations for both drive mechanisms were introduced and a Fortran code was written for the solution. Piston strokes, cylinder and displacer diameters, hot and cold end temperatures, regenerator volumes and heat transfer surface areas were taken equal for both engines with two different drive mechanisms. In the analysis, air was used as the working gas. Engine power and efficiency were compared for different charge pressure values, working gas mass values, heat transfer coefficients and hot end temperatures. Maximum specific engine power was 1410 W/L for the engine with rhombic drive mechanism and 1200 W/L for the engine with crank drive mechanism at 4 bars of charge pressure and 500 W/m"2K heat transfer coefficient. Rhombic drive mechanism was relatively advantageous at low working gas mass values and high hot end temperatures. In comparison with the engine having rhombic drive mechanism, the relatively poor kinematic behaviour of the engine having crank drive mechanism caused lower engine efficiency and performance. Heat transfer coefficient was also predicted by using an experimental pressure trace.

    There is controversy over the real existence of differences in mental health and academic performance between the Mapuche ethnic minority male adolescents and the male adolescents not belonging to this ethnicity in Chile. In consequence, the aim of this study was to investigate the differences in emotional and behavioural symptoms, risky behaviours and academic success on the Chilean Mapuche and non-Mapuche adolescents. The sample consisted of 233 adolescents of which 119 were Mapuche adolescents and 114 were non-Mapuche adolescents. The results showed that the Mapuche adolescents do not have more anxiety problems and depression than the non-Mapuche adolescents. Furthermore, the Mapuche adolescents present less drug consumption and behavioural problems. Moreover, there were no differences in academic performance. This study provides social interest data of the adolescents' mental health, which can be useful for the country's socio-sanitary and political decisions. Future studies should investigate these and other variables related to the mental health of minorities in greater depth.

    There is no systematic identification of parents with excessive alcohol use who have a child admitted to hospital. Children in families with excessive alcohol issues form a high risk group as substantial alcohol consumption has a damaging influence on a child emotionally, cognitively, socially and physically. Alcohol consumption is a sensitive issue, and health staff needs knowledge, qualifications and adequate training in communicating with parents about this taboo. • To identify specific patterns in subgroups of parents by comparing results from screening and demographic variables • To identify systematic patterns in staff members by demographic variables to decide whether these factors influence the screening results. During 1 year, screening and brief intervention (SBI) was accomplished, including health staff conducting dialogues with parents of a hospitalized child using motivational interviewing (MI) and screening for risky alcohol behaviour by Cut down, Annoyance from others, feel Guilty, Early-morning Craving (CAGE)-C. Data were analysed by descriptive statistics, and relationships were tested with a statistical significance level of 0.05, using SPSS (version 16.0). Motivational dialogues with 779 parents were conducted by 43 staff members, and 11% of the parents were screened positive for risky alcohol behaviour. Drinking alcohol 4 days a week or more and drinking alcohol outside mealtimes were main risk factors. Parents' gender was the strongest predictor of screening positive and OR was 6.8 for men (CI 4.03-11.74) compared to women, pparents' age (CI 1.02-1.42) indicates the risk of screening positive increases with age, p=0.027. Brief intervention using CAGE-C and MI has proven successful in mapping parents' alcohol consumption patterns and in identifying parents with risky alcohol consumption habits. Health staff is able to manage health promotion and prevention when having the right competences and when being supervised. © 2010 The Authors

  13. Alcohol Dependence and Altered Engagement of Neural Networks in Risky Decisions

    Full Text Available Alcohol dependence is associated with heightened risk tolerance and altered decision- making. This raises the question as to whether alcohol dependent patients (ADP are incapable of proper risk assessment. We investigated how healthy controls (HC and ADP engage neural networks to cope with the increased cognitive demands of risky decisions. We collected fMRI data while 34 HC and 16 ADP played a game that included safe and risky trials. In safe trials, participants accrued money at no risk of a penalty. In risky trials, reward and risk simultaneously increased as participants were instructed to decide when to stop a reward accrual period. If the participant failed to stop before an undisclosed time, the trial would bust and participants would not earn the money from that trial. Independent Component Analysis was used to identify networks engaged during the anticipation and the decision execution of risky compared with safe trials. Like HC, ADP demonstrated distinct network engagement for safe and risky trials at anticipation. However, at decision execution, ADP exhibited severely reduced discrimination in network engagement between safe and risky trials. Although ADP behaviorally responded to risk they failed to appropriately modify network engagement as the decision continued, leading ADP to assume similar network engagement regardless of risk prospects. This may reflect disorganized network switching and a facile response strategy uniformly adopted by ADP across risk conditions. We propose that aberrant salience network (SN engagement in ADP might contribute to ineffective network switching and that the role of the SN in risky decisions warrants further investigation.

    Full Text Available Driving is a multifactorial behaviour drawing on multiple cognitive, sensory, and physical systems. Dementia is a progressive and degenerative neurological condition that impacts the cognitive processes necessary for safe driving. While a number of studies have examined driving among individuals with Alzheimer’s disease, less is known about the impact of Dementia with Lewy Bodies (DLB on driving safety. The present study compared simulated driving performance of 15 older drivers with mild DLB with that of 21 neurologically healthy control drivers. DLB drivers showed poorer performance on all indicators of simulated driving including an increased number of collisions in the simulator and poorer composite indicators of overall driving performance. A measure of global cognitive function (i.e., the Mini Mental State Exam was found to be related to the overall driving performance. In addition, measures of attention (i.e., Useful Field of View, UFOV and space processing (Visual Object and Space Perception, VOSP, Test correlated significantly with a rater’s assessment of driving performance.

    Although research has documented negative effects of combat deployment on mental health, few studies have examined whether deployment increases risky or self-destructive behavior. The present study addressed this issue. In addition, we examined whether deployment effects on risky behavior varied depending on history of pre-deployment risky behavior, and assessed whether psychiatric conditions mediated effects of deployment on risky behavior. In an anonymous survey, active duty members of the U.S. Marine Corps and U.S. Navy (N = 2116) described their deployment experiences and their participation in risky recreational activities, unprotected sex, illegal drug use, self-injurious behavior, and suicide attempts during three time frames (civilian, military pre-deployment, and military post-deployment). Respondents also reported whether they had problems with depression, anxiety, or PTSD during the same three time frames. Results revealed that risky behavior was much more common in civilian than in military life, with personnel who had not deployed, compared to those who had deployed, reporting more risky behavior and more psychiatric problems as civilians. For the current time period, in contrast, personnel who had deployed (versus never deployed) were significantly more likely to report both risky behavior and psychiatric problems. Importantly, deployment was associated with increases in risky behavior only for personnel with a pre-deployment history of engaging in risky behavior. Although psychiatric conditions were associated with higher levels of risky behavior, psychiatric problems did not mediate associations between deployment and risky behavior. Implications for understanding effects of combat deployment on active duty personnel and directions for future research are discussed. Published by Elsevier Ltd.

    The role of peer harassment in the association between sexual minority status and adolescent risky behavior was examined for 15-year-olds in the NICHD Study of Early Child Care and Youth Development (n = 957). The findings, although exploratory, suggest the importance of gender. For girls, peer harassment was best viewed as a moderator of the link between sexual minority status and increased risky behavior. It intensified an existing association, reflecting the gendered nature of the impact of sexual minority status on the adolescent social context. For boys, peer harassment was primarily a mediator, such that sexual minority status was associated with more risky behavior via elevated harassment, although sexual minority status itself was associated with lower risky behavior overall.

    Self-esteem, a value one places on oneself, influences one's cognitive, emotional and behavioral responses across various situations. In the case of risky decision-making, high self-esteem (SE) individuals rely on their positive self-views and tend to be less defensive in response to a risky task; low SE individuals, on the contrary, tend to have fewer accessible positive resources and thus, are more prone to risk-aversion. While past studies have provided evidence for a link between self-esteem and a behaviorally-risky response, no study has explored the relation between self-esteem and the electrophysiological correlates of risky response. Therefore, the current study investigated the correlates of risky decision-making in high SE compared to low SE participants using event-related potentials (ERP) technology in 28 undergraduate students playing a blackjack game. The results showed that there was no difference between the high SE participants and the low SE participants with respect to the behavioral assessments of the risk-taking decision-making. However, for the electrophysiological data, we observed that the amplitude of P2 (150-300 ms) was more positive in the high SE participants compared to the low SE participants over the central-posterior scalp region. Dipole source analysis indicated that this positive component was generated in posterior cingulate cortex (PCC). These findings suggest that the high SE participants experienced more emotional signals than the low SE participants during decision-making.

  18. Acute stress does not affect risky monetary decision-making

    Full Text Available The ubiquitous and intense nature of stress responses necessitate that we understand how they affect decision-making. Despite a number of studies examining risky decision-making under stress, it is as yet unclear whether and in what way stress alters the underlying processes that shape our choices. This is in part because previous studies have not separated and quantified dissociable valuation and decision-making processes that can affect choices of risky options, including risk attitudes, loss aversion, and choice consistency, among others. Here, in a large, fully-crossed two-day within-subjects design, we examined how acute stress alters risky decision-making. On each day, 120 participants completed either the cold pressor test or a control manipulation with equal probability, followed by a risky decision-making task. Stress responses were assessed with salivary cortisol. We fit an econometric model to choices that dissociated risk attitudes, loss aversion, and choice consistency using hierarchical Bayesian techniques to both pool data and allow heterogeneity in decision-making. Acute stress was found to have no effect on risk attitudes, loss aversion, or choice consistency, though participants did become more loss averse and more consistent on the second day relative to the first. In the context of an inconsistent previous literature on risk and acute stress, our findings provide strong and specific evidence that acute stress does not affect risk attitudes, loss aversion, or consistency in risky monetary decision-making.

  19. Is international exploration really more risky

    Over the past few years many Canadian oil producers have shifted their exploration efforts to finding larger reserves outside of Canada. Evaluation of such international projects requires the same type of economic analysis as is carried out for domestic projects, essentially discounted cash flow or net present value analysis. Applying this evaluation methodology requires two types of data: a series of forecasted cash flows and an appropriate hurdle rate. Conventional wisdom states that foreign projects should be evaluated at a higher discount rate than domestic projects. This wisdom is called into question. While some overseas projects may indeed be of higher risk, especially unconventional projects or those located in politically unstable areas, it is not obvious that overseas projects located in politically stable economies and comparable technologically to domestic projects are indeed more risky. In addition to evaluating the market riskiness of overseas projects, the extent to which on-going globalization of world financial markets might impact the riskiness of both domestic and overseas investments in the energy industry is assessed. It is indicated that it may be appropriate for Canadian oil and gas companies to revisit the methods used to measure their corporate hurdle rates in light of this globalization process. 3 tabs

    The Export Development Corporation (EDC) supports Canadian exporters and investors in international projects by providing export credit insurance for commodities and by providing financing for projects ranging from chemical plants to pipeline projects. EDC has been an active participant in financing projects in 'risky markets' in China, Columbia, India, Indonesia, Mexico, Russia and Venezuela. This presentation reviewed the origins and dimensions of the Asian crisis and how the spillover effects are showing up in most regions of the world. It was suggested that the factors which contributed to the crisis were: (1) growing macroeconomic imbalances, (2) excessive private capital inflows financing risky and low-profitability ventures, (3) financial sector mismanagement, (4) political uncertainty, and (5) decline in investor confidence. The Asian financial crisis will affect other developing countries in the following ways: (1) shrinking foreign private capital flows, (2) widening spreads for foreign and private borrowers, (3) reduced trade volumes due to import compression, (4) lower prices for traded goods, (5) depressed international interest rates. As a result of the Asian crisis, banks in Japan, Korea, Singapore, Europe and North America have cancelled or restructured several billion dollars in loans. Several projects are now under review, have been delayed or cancelled. It was suggested that significant changes in risk management strategies must be made in order for the countries of Asia to restructure their economies. Putting an end to 'cronyism' establishing well-supervised banking, legal and court systems that are up-to-date and transparent, are also essential ingredients of recovery

    This study was designed to examine prospective associations of risky family environments with subsequent levels of negative emotions and peripheral blood mononuclear cell telomere length (TL), a marker of cellular aging. A second purpose was to determine whether negative emotions mediate the hypothesized link between risky family processes and diminished telomere length. Participants were 293 adolescents (age 17 years at the first assessment) and their primary caregivers. Caregivers provided data on risky family processes when the youths were age 17 years, youths reported their negative emotions at age 18 years, and youths' TL was assayed from a blood sample at age 22 years. The results revealed that (a) risky family processes forecast heightened negative emotions (β = .316, p emotions forecast shorter TL (β = -.187, p = .012), and (c) negative emotions served as a mediator connecting risky family processes with diminished TL (indirect effect = -0.012, 95% CI [-0.036, -0.002]). These findings are consistent with the hypothesis that risky family processes presage premature cellular aging through effects on negative emotions, with potential implications for lifelong health.

    Children's risky play is associated with a variety of positive developmental, physical and mental health outcomes, including greater physical activity, self-confidence and risk-management skills. Children's opportunities for risky play have eroded over time, limited by parents' fears and beliefs about risk, particularly among mothers. We developed a digital tool and in-person Risk-reframing (RR) workshop to reframe parents' perceptions of risk and change parenting behaviours. The purpose of this paper is to describe our RR intervention, rationale and protocol for a randomised controlled trial to examine whether it leads to increases in mothers' tolerance of risk in play and goal attainment relating to promoting their child's opportunities for risky play. We use a randomised controlled trial design and will recruit a total of 501 mothers of children aged 6-12 years. The RR digital tool is designed for a one-time visit and includes three chapters of self-reflection and experiential learning tasks. The RR in-person tool is a 2-h facilitated workshop in which participants are guided through discussion of the same tasks contained within the digital tool. The control condition consists of reading the Position Statement on Active Outdoor Play. Primary outcome is increased tolerance of risk in play, as measured by the Tolerance of Risk in Play Scale. Secondary outcome is self-reported attainment of a behaviour-change goal that participants set for themselves. We will test the hypothesis that there will be differences between the experimental and control conditions with respect to tolerance of risk in play using mixed-effects models. We will test the hypothesis that there will be differences between the experimental and control conditions with respect to goal attainment using logistic regression. The results of this trial will have important implications for facilitating the widespread change in parents' risk perception that is necessary for promoting broad societal

    The main objective of this study was to analyze and estimate the relations between risky riding behaviors and some personality and sociocognitive variables through structural equation modeling. We focused on two-wheel riding behavior among a sample of 1,028 Italian adolescents at their first driving experience. The main findings confirmed the role of personality in influencing riding behavior directly as well as indirectly through risk perception. In particular, risk perception was a significant mediator between personality, social norm, and riding behavior. The significant relations that emerged in the general sample were further confirmed in the two specific sub-samples of males and females. In terms of social marketing and educational communication, it may consequently be advisable to proceed in an integrated and coordinated manner at both the cognitive and social level, taking into account some "dispositions to risk" related to personality. The integrated and coordinated action on different levels--cognitive, social, and personality--may therefore allow more effective and significant results in reducing those risky riding behaviors that often underlie young two-wheel riders' higher involvement in traffic accidents.

    Full Text Available Driving under the influence of alcohol and substance use is an important traffic problem that caused many people in the world to lose their lieves. Many features that are important in terms of driving adversely affected under the influence of alcohol and substance and therefore impaired driving behavior arises in drivers. The most effective way to fight for prevent this impaired driver behavier is the restrictions and regulations imposed on drivers in traffic related to alcohol and drug use. Nevertheless, in the literature, some drivers continue to impaired driving function with a risky traffic behavior, in which the driver personality (risk-taking, thrill-seeking, self-control, psychopathological (substance abuse, personality disorders, mood disorders, attention deficit hyperactivity disorder, post-traumatic stress disorder, anxiety, anger and aggression, and many other neuropsychological features are considered to have a relationship with this situation. In this article psychological, psychopathological and neuropsychological studies have examined regarding drive under the influence of alcohol and drug.

    This study was undertaken to assess the association between adult attention deficit/hyperactivity disorder (ADHD) symptoms and high-risk sexual behavior. This cross-sectional study interviewed 462 low-income women aged 18-30 years. We used the 18-item Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist to assess ADHD symptoms. Risky sexual behaviors included sex before 15 years of age, risky sex partners in lifetime, number of sex partners in the last 12 months, condom use in the last 12 months, alcohol use before sex in the last 12 months, traded sex in lifetime, and diagnosed with sexually transmitted infection (STI) in lifetime. Mean ADHD symptom score was 19.8 (SD±12.9), and summary index of all risky sexual behavior was 1.77 (SD±1.37). Using unadjusted odds ratios (OR), women who endorsed more ADHD symptoms reported engaging in more risky sexual behaviors of all types. However, when multivariable logistic regression was applied adjusting for various sociodemographic covariates, the adjusted ORs remained significant for having risky sex partners and having ≥3 sex partners in the prior 12 months. We observed some differences in risky sexual behavior between two domains of ADHD. The ADHD symptom score appears to be associated with some risky sexual behaviors and deserves further attention. A brief ADHD screening can identify this high-risk group for timely evaluation and safe sex counseling.

    Objective To examine dating violence perpetration and victimization (physical, psychological, and sexual) and lifetime substance use (alcohol, marijuana, and hard drugs) as longitudinal predictors of adolescents’ risky sexual behavior across one year, and to determine whether predictors varied across adolescents’ gender and ethnicity. Methods A sample of Caucasian, African American, and Hispanic male and female adolescents from 7 public high schools in Texas (N = 882) participated. Adolescents completed self-report measures of dating violence, lifetime substance use, and risky sexual behavior at baseline and, 1-year later, completed a second assessment of their risky sexual behavior. Results Path analysis demonstrated that greater physical dating violence victimization, lifetime alcohol use, lifetime marijuana use, and age (being older) were all significant predictors of risky sexual behavior at the 1-year follow-up. These results did not vary across gender or the three ethnic groups (Caucasian, African American, and Hispanic). Conclusions Overall, substance use was a longitudinal predictor of risky sexual behavior across the three ethnic groups, with physical dating violence victimization being the only type of dating violence longitudinally predicting risky sexual behavior. Prevention efforts should consider the roles of physical dating violence and substance use in preventing risky sexual behavior. PMID:25797949

    Background Ethnographic evidence suggests that transactional sex is sometimes motivated by youth’s interest in the consumption of modern goods as much as it is in basic survival. There are very few quantitative studies that examine the association between young people’s interests in the consumption of modern goods and their sexual behaviour. We examined this association in two regions and four residence zones of Madagascar: urban, peri-urban and rural Antananarivo, and urban Antsiranana. We expected risky sexual behaviour would be associated with interests in consuming modern goods or lifestyles; urban residence; and socio-cultural characteristics. Methods We administered a population-based survey to 2, 255 youth ages 15–24 in all four residence zones. Focus group discussions guided the survey instrument which assessed socio-demographic and economic characteristics, consumption of modern goods, preferred activities and sexual behaviour. Our outcomes measures included: multiple sexual partners in the last year (for men and women); and ever practicing transactional sex (for women). Results Overall, 7.3% of women and 30.7% of men reported having had multiple partners in the last year; and 5.9% of women reported ever practicing transactional sex. Bivariate results suggested that for both men and women having multiple partners was associated with perceptions concerning the importance of fashion and a series of activities associated with modern lifestyles. A subset of lifestyle characteristics remained significant in multivariate models. For transactional sex bivariate results suggested perceptions around fashion, nightclub attendance, and getting to know a foreigner were key determinants; and all remained significant in multivariate analysis. We found peri-urban residence more associated with transactional sex than urban residence; and ethnic origin was the strongest predictor of both outcomes for women. Conclusions While we found indication of an association

    Full Text Available This paper considers young people's sexual decision-making in the context of New Labour's policies on teenage pregnancy. In 1999, the newly formed Social Exclusion Unit sought to understand why the UK had the highest number of teenage conceptions in Europe (SEU 1999. One of the conclusions was that young people in the UK are engaging in "risky" rather than "safe" sex. Although New Labour has since developed policies designed to help young people avoid what is seen as risky sexual activity, there is a tension in sexual health policy between the overall aim of providing young people with the knowledge and confidence to practice "safe sex", and an underlying belief amongst many in the undesirability of "underage sex". This is partly a legacy of disagreements evident in the 1980s and 1990s when some organisations argued against sex education and contraceptive provision for young people on the grounds that it encouraged promiscuous and risky behaviour. The paper shows how alternative meanings of risk and responsibility are present in young mothers' own representations of their sexual decision-making. It does this through an analysis of two research projects on Young Women, Sex and Choices. URN: urn:nbn:de:0114-fqs0601283

    The technical advancement of driving simulators has decreased their cost and increased both their accuracy and fidelity. This makes them a useful tool for examining driving behavior in risky or unique situations. With the approaching increase of older licensed drivers due to aging of the baby boomers, driving simulators will be important for conducting driving research and evaluations for older adults. With these simulator technologies, some people may experience significant effects of a unique form of motion sickness, known as simulator sickness. These effects may be more pronounced in older adults. The present study examined the feasibility of an intervention to attenuate symptoms of simulator sickness in drivers participating in a study of a driving evaluation protocol. Prior to beginning the experiment, the experimental groups did not differ in subjective simulator sickness scores as indicated by Revised Simulator Sickness Questionnaire scores (all p>0.5). Participants who experienced a two-day delay between an initial acclimation to the driving simulator and the driving session experienced fewer simulator sickness symptoms as indicated by RSSQ total severity scores than participants who did not receive a two-day delay (F(1,88)=4.54, p=.036, partial η(2)=.049). These findings have implications for improving client well-being and potentially increasing acceptance of driving simulation for driving evaluations and for driving safety research.

    This study evaluates prevalence and trends in drugged driving in Canada based on multiple indicators collected from the Road Safety Monitor (RSM) and Canada's National Fatality Database maintained by the Traffic Injury Research Foundation (TIRF). The objective of this paper is to identify the state of drug-positive driving in Canada, as well as to make comparisons with data from previous years to determine whether changes have occurred. Available data from the RSM on self-reported drugged driving behaviours were collected and analyzed using multivariate techniques in various years spanning from 2002 to 2015. Data from TIRF's National Fatality Database from 2000 to 2012 were also analyzed to evaluate trends and prevalence of drugs in fatally injured drivers across Canada. Additionally, differences among drugged drivers with respect to gender and age were studied. Analyses of the RSM data and of the National Fatality Database showed that, as a whole, the prevalence of drugged driving has remained relatively stable over the past decade, with some changes noticed in specific years for some drug types. Specifically from the RSM, there was a 62.5% increase from the 1.6% of drivers reporting driving within two hours of using marijuana in 2013 to 2.6% in 2015. The analyses of the fatality data revealed a 16.9% increase in the percentage of fatally injured drivers testing positive for drugs between 2000 and 2012 (from 33.56% to 39.24%). Cocaine-positive fatally injured drivers increased from 3.6% in 2000 to 6.2% in 2012. Similarly, marijuana-positive fatally injured drivers increased from 12.8% in 2000 to 19.7% in 2012. Results showed varying characteristics with respect to gender and age among self-reported and fatally injured drugged drivers. Drugged driving behaviours remain prevalent among Canadian drivers and drugs continue to be found in over one-third of tested fatally injured drivers. Although self-reported behaviours have neither decreased nor increased overall in

    The Theory of Planned Behaviour (TPB) plus moral norms, anticipated regret, past behaviour, self-identity and perceived susceptibility was applied to predicting motorcyclists' intention to ride above the speed limit and ride at inappropriate speeds. Past behaviour, control beliefs, attitudes, moral norm, normative beliefs, age and self-identity explained 60% of the variance in motorcyclists' intention to exceed the speed limit on motorways (N=1381). A total of 62% of the variance in motorcyclists' intention to really go for it on rural roads was accounted for, with past behaviour, attitudes, control beliefs, age, normative beliefs, anticipated regret, self-identity, behavioural beliefs and training status being significant (N=1116). Finally, attitudes, past behaviour, control beliefs, moral norm, anticipated regret, behavioural beliefs, normative beliefs, engine size and self-identity explained 57% of the variance in motorcyclists' intention to ride faster than felt safe in order to keep up with the group (N=1940). The belief-based measures also successfully differentiated between those who intended to speed and those who did not. Theoretical and practical implications of the findings are discussed.

    Warp drives, at least theoretically, provide a way to travel at superluminal speeds. However, even if one succeeded in providing the necessary exotic matter to construct them, it would still be necessary to check whether they would survive to the switching on of quantum effects. In this contribution we will report on the behaviour of the Renormalized Stress-Energy Tensor (RSET) in the spacetimes associated with superluminal warp drives. We find that the RSET will exponentially grow in time close to the front wall of the superluminal bubble, hence strongly supporting the conclusion that the warp-drive geometries are unstable against semiclassical back-reaction.

    Existing studies suggest that individual and household level economic shocks affect the demand for and supply of risky sex. However, little evidence exists on the effects of an aggregate shock on equilibrium risky sexual behavior. This paper examines the effects of the early twenty-first century copper boom on risky sexual behavior in Zambian copper mining cities. The results indicate that the copper boom substantially reduced rates of transactional sex and multiple partnerships in copper min...

    Full Text Available Objective: This study aimed to identify certain risky behavior patterns (unsafe sex, tobacco and drug use, and binge drinking and the factors affecting these behaviors among first- and third-year students in a university. Method: The study included a total of 8407 students enrolled as first- (4392 and third- (4015 year students. A self-administered questionnaire was used for data collection. In data analysis, respecting sampling weights, models were formed by logistic regression method to determine factors that affect the risky behaviors. Results: 731 male–1114 female students from the first year and 560 male–1096 female students from the third year were interviewed. Male students were found to be engaged in risky behaviors more frequently than females. Logistic models of the study indicated that gender, place of residence, relationship with parents, and socialization with friends have profound effects on risky behaviors. Conclusion: After leaving home, young people develop their own lifestyles, and this study demonstrates that lifestyle is the main effective factor for risky behaviors in this group. Universities need to assume more responsibility to guide students’ lives and to provide the facilities and opportunities that encourage and facilitate their adoption of a healthy lifestyle.   Key Words: University students, risky behaviours Bir Üniversitede Öğrencilerin Riskli Davranışları: Kesitsel Bir Çalışma Amaç: Bu çalışmanın amacı, bir üniversitenin birinci ve üçüncü sınıf öğrencileri arasında bazı riskli davranış modellerini (güvensiz seks, tütün ve uyuşturucu kullanımı ve aşırı alkol ve bu davranışları etkileyen faktörleri saptamaktır.

    Adolescents in sexual minority groups are known to be at risk of contracting sexually transmitted diseases through risky sexual behavior. However, few studies have examined associations between sexual orientation and risky sexual behavior and sexually transmitted diseases in Korean adolescents. Therefore, this cross-sectional study used raw data from the Tenth Korea Youth Risk Behavior Web-Based Survey to explore these relationships. Logistic regression analyses were performed to examine the associations between risky sexual behavior and sexual orientation in adolescents. The participants were 6,884 adolescents who provided data regarding demographic characteristics, sexual orientation, and risky sexual behavior. The proportions of homosexual and bisexual subjects who used condoms, engaged in sexual intercourse after drinking alcohol, and experienced sexually transmitted diseases were higher relative to those of heterosexual subjects. Associations between homosexuality and bisexuality and sexually transmitted diseases and engagement in sexual intercourse after drinking remained after multivariate adjustment. Interventions to prevent risky sexual behavior should target sexual orientation, to improve sexual health and prevent sexually transmitted disease in homosexual and bisexual adolescents.

    Full Text Available This study examines the knowledge of HIV/AIDS, attitudes towards risky sexual behaviour and perceived behavioural control among students in Botswana. Data were collected from 445 students randomly selected from the University of Botswana and Boitekanelo College. Hundred and seventy three males and 272 females participated in the study. The study established that although more than 90% of students correctly identified routes of HIV transmission, misconceptions regarding HIV/AIDS still exist. This includes the belief that people can be infected with HIV because of witchcraft and that only people who have sex with gay or homosexual partners can be infected with HIV. Majority of students were aware of various sexual risks. However, the percentage of students who indicated that “it is difficult to ask my partner to use a condom” was still relatively high (13.5% based on the assumption that students are supposed to know the consequences of sexual risky behaviour. It was also found that male students were 3.48 times more likely to negotiate sex than their female counterparts (OR = 3.48, 95% CI: 1.09 − 11.13 and students who were 18 years and below were more likely to negotiate sex than students above 18 years of age (OR = 2.78, 95% CI: 1.42 − 18.32. Christians are four times less likely to negotiate sex compared to non-Christians (OR = 0.219, 95% CI: 0.095 − 0.506. More than 80% of students were comfortable discussing HIV or sex and sexuality with their friends, boyfriends/girlfriends or partners but uncomfortable discussing the same issues with their parents.

    The aim of this study was to determine to what extent the theory of planned behaviour (TPB) extended with moral norm and descriptive norm is able to predict intentions not to drink and drive. We also wanted to examine whether different processes guide intentions among young drivers (35 years and below) versus drivers aged above 35 years, and women's versus men's intentions. Questionnaires were sent to a sample of 4000 people in Norway aged between 18 and 70 years, and were completed by 1025 respondents. Analyses were conducted among those who had a driver's licence and who reported drinking at least 1-2 times per year, resulting in a sample of 879 individuals (46.6% were men, 30.3% were 35 years and younger, M=43.9 years). The results showed that the TPB variables explained 10% of the variance in intentions in the sample as a whole, and that the extension variables added 2% to the explained variance after controlling for the impact of the TPB components. Perceived behavioural control was the strongest predictor of intentions (β=0.24, pdrive will be outlined. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Previous research examining social influences on driving behavior has primarily focused on the effects of passengers and surrounding vehicles (e.g., speed contagion. Of current interest was the interaction between drivers that occurs in a “following a friend” scenario, i.e., the driver of one vehicle (the leader knows how to get to the desired destination while the driver of a second vehicle (the follower does not. Sixteen participants drove through a simulated city in a driving simulator under three conditions: (i a baseline condition in which they could choose their own route, (ii a navigation system condition in which they were given audible route instructions, and (iii a “follow a friend” condition in which they required to follow a simulated vehicle. In the follow a friend condition, drivers engaged in significantly more risky behaviors (in comparison to the other conditions such as making more erratic and higher speed turns and lane changes, maintaining overall higher speed, as well as maintaining a shorter time headway when following a lead vehicle. These effects suggest a relationship to time pressure caused by a fear of getting lost.

    Neuroimaging allows to estimate brain activity when individuals are doing something. The location and intensity of this estimated activity provides information on the dynamics and processes that guide choice behaviour and associated actions that should be considered a complement to behavioural studies. Decision neuroscience therefore sheds new light on whether the brain evaluates and compares alternatives when decisions are made, or if other processes are at stake. This work helped to demonstrate that the situations faced by individuals (risky, uncertain, delayed in time) do not all have the same (behavioural) complexity, and are not underlined by activity in the cerebral networks. Taking into account brain dynamics of people (suffering from obesity or not) when making food consumption decisions might allow for improved strategies in public health prevention, far from the rational choice theory promoted by neoclassical economics. © 2011 médecine/sciences – Inserm / SRMS.

    This article investigates the attitudes and behavior of Greek drivers with specific focus on mobile phone use while driving. The research is based on the data of the pan-European SARTRE 4 survey, which was conducted on a representative sample of Greek drivers in 2011. Analysis of the drivers' behavior was carried out by the statistical methods of factor and cluster analysis. According to the results of factor analysis, Greek drivers' responses in the selected questions were summarized into 4 factors, describing road behavior and accident involvement probability as well as their views on issues concerning other drivers' road behaviors, fatigued driving, enforcement of road safety, and mobile phone use while driving. The results of cluster analysis indicated 5 different groups of Greek drivers--the moderate, the optimistic, the conservative, the risky, and the reasonably cautious--and the characteristics of each group where identified. These results may be useful for the appropriate design of targeted road safety campaigns and other countermeasures.

    To describe empirically the risky sexual behavior of an at-risk sample of adolescent girls, to assess psychosocial correlates of risky behavior, and to examine the utility of applying a risk and protective model to predicting teens' risky sexual behavior. Participants included 158 African American girls, ages 12 to 19, who were receiving medical care in an adolescent primary care clinic. Teens completed measures of depression, conduct problems, substance use, peer norms, social support, HIV knowledge, sexual self-efficacy, and sexual behavior. Teens in this sample reported high rates of risky sexual behaviors, including early sexual debuts and frequent unprotected sexual encounters with multiple partners. African American girls who reported high rates of substance use and who reported that their peers engaged in risky behaviors also reported engaging in high rates of risky sexual behaviors. Little support was obtained for protective factors (HIV knowledge, social support, sexual self-efficacy) moderating the relations between risk factors and adolescents' risky sexual behavior in this sample. Teens presenting in primary care settings in urban environments seem to be at high risk for HIV, STDs, and substance abuse, and risk reduction strategies should be introduced during the preteen years. An interdisciplinary model of care in primary care settings serving adolescents is clearly indicated, and prevention-oriented interventions aimed at reducing risky behaviors and preventing the development of more significant health, mental health, or substance abuse disorders are needed.

    Driver sleepiness is a major contributor to road crashes. The current study sought to examine the association between perceptions of effectiveness of six sleepiness countermeasures and their relationship with self-reports of continuing to drive while sleepy among 309 drivers after controlling for the influence of age, sex, motivation for driving sleepy, and risk perception of sleepy driving. The results demonstrate that the variables of age, sex, motivation, and risk perception were significantly associated with self-reports of continuing to drive while sleepy and only one countermeasure was associated with self-reports of continuing to drive while sleepy. Further, it was found that age differences in self-reports of continuing to drive while sleepy was mediated by participants' motivation and risk perception. These findings highlight modifiable factors that could be focused on with interventions that seek to modify drivers' attitudes and behaviours of driving while sleepy. Copyright © 2014 Elsevier Ltd.

    Risky sexual practice is a major public health problem in Ethiopia. There are various studies on the prevalence and determinants of risky sexual practice in different regions of the country but there is no study which shows the national estimate of risky sexual practices in Ethiopia. Therefore, this review was conducted to estimate the national pooled prevalence of risky sexual practice and its risk factors in Ethiopia. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline was followed to review published and unpublished studies in Ethiopia. The databases used were; PubMed, Google Scholar, CINAHL and African Journals Online. Search terms were; risky sexual behavior, risky sexual practice, unprotected sex, multiple sexual partner, early sexual initiation, and/or Ethiopia. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument was used for critical appraisal. The meta-analysis was conducted using Review Manager software. Descriptive information of studies was presented in narrative form and quantitative results were presented in forest plots. The Cochran Q test and I 2 test statistics were used to test heterogeneity across studies. The pooled estimate prevalence and the odd ratios with 95% confidence intervals were computed by a random effect model. A total of 31 studies with 43,695 participants were included in the meta-analysis. The pooled prevalence of risky sexual practice was 42.80% (95% CI: 35.64%, 49.96%). Being male (OR: 1.69; 95% CI: 1.21, 2.37), substance use (OR: 3.42; 95% CI: 1.41, 8.31), peer pressure (OR: 3.41; 95% CI: 1.69, 6.87) and watching pornography (OR: 3.6; 95% CI: 2.21, 5.86) were factors associated with an increase in risky sexual practices. The prevalence of risky sexual practices is high in Ethiopia. Being male, substance use, peer pressure and viewing pornographic materials were found to be associated with risky sexual practices. Therefore, life skills training is recommended to

    Behavioural addictions are characterized by an inability to resist an urge or drive resulting in actions that are harmful to oneself or others. Behavioural addictions share characteristics with substance and alcohol abuse, and in areas such as natural history, phenomenology, and adverse consequences. Behavioural addictions include pathological gambling, kleptomania, pyromania, compulsive buying, compulsive sexual behaviour, Internet addiction, and binge eating disorder. Few studies have examined the efficacy of pharmacological and psychological treatment for the various behavioural addictions, and therefore, currently, no treatment recommendations can be made.

    A significant minority of parents are concerned about adolescents engaging in risky sexual behavior following human papillomavirus (HPV) vaccination. The way the HPV vaccine is reported in the media has the potential to influence public understanding and vaccination decisions. The present study examined the content of articles published between 2003 and 2008 in British national newspapers that addressed the issue of adolescents engaging in risky sexual behavior following HPV vaccination. We used mixed methods to analyze 92 articles in which the issue was mentioned. Qualitative framework analysis highlighted three main types of discussion: news stories proposing that adolescents will engage in risky sexual behavior following HPV vaccination, counterarguments insisting that adolescents will not engage in risky sexual behavior after HPV vaccination, and parents' views of the issue of risky sexual behavior. The results indicated that newspapers provide parents with broadly positive descriptive norms about vaccination; however, the issue that adolescents will engage in risky sexual behaviors following HPV vaccination is regularly discussed in the national press and has the potential to increase parents' concerns about vaccination.

    To develop and validate a risky sexual behavior index specific to cervical cancer research. Sexual behavior data on 428 women from the Community Awareness Resources and Education (CARE) study were utilized. A weighting scheme for eight risky sexual behaviors was generated and validated in creating the CARE Risky Sexual Behavior Index. Cutpoints were then identified to classify women as having a low, medium, or high level of risky sexual behavior. Index scores ranged from 0 to 35, with women considered to have a low level of risky sexual behavior if their score was less than six (31.3% of sample), a medium level if their score was 6–10 (30.6%), or a high level if their score was 11 or greater (38.1%). A strong association was observed between the created categories and having a previous abnormal Pap smear test (p Sexual Behavior Index provides a tool for measuring risky sexual behavior level for cervical cancer research. Future studies are needed to validate this index in varied populations and test its use in the clinical setting.

    Risky patterns of alcohol use prior to pregnancy increase the risk of alcohol-exposed pregnancies and subsequent adverse outcomes. It is important to understand how consumption changes once women become pregnant. The aim of this study was to describe the characteristics of women that partake in risky drinking patterns before pregnancy and to examine how these patterns change once they become pregnant. A sample of 1577 women from the 1973-78 cohort of the Australian Longitudinal Study on Women's Health were included if they first reported being pregnant in 2000, 2003, 2006, 2009 and reported risky drinking patterns prior to that pregnancy. Multinomial logistic regression was used to determine which risky drinking patterns were most likely to continue into pregnancy. When reporting risky drinking patterns prior to pregnancy only 6% of women reported weekly drinking only, whereas 46% reported binge drinking only and 48% reported both. Women in both binge categories were more likely to have experienced financial stress, not been partnered, smoked, used drugs, been nulliparous, experienced a violent relationship, and were less educated. Most women (46%) continued these risky drinking patterns into pregnancy, with 40% reducing these behaviors, and 14% completely ceasing alcohol consumption. Once pregnant, women who binged only prior to pregnancy were more likely to continue (55%) rather than reduce drinking (29%). Of the combined drinking group 61% continued to binge and 47% continued weekly drinking. Compared with the combined drinking group, binge only drinkers prior to pregnancy were less likely to reduce rather than continue their drinking once pregnant (OR = 0.37, 95% CI  =  0.29, 0.47). Over a third of women continued risky drinking into pregnancy, especially binge drinking, suggesting a need to address alcohol consumption prior to pregnancy.

    Multitasking, such as the concurrent use of a mobile phone and operating a motor vehicle, is a significant distraction that impairs driving performance and is becoming a leading cause of motor vehicle crashes. This study investigates the impact of mobile phone conversations on car-following behaviour. The CARRS-Q Advanced Driving Simulator was used to test a group of young Australian drivers aged 18-26 years on a car-following task in three randomised phone conditions: baseline (no phone conversation), hands-free and handheld. Repeated measure ANOVA was applied to examine the effect of mobile phone distraction on selected car-following variables such as driving speed, spacing, and time headway. Overall, drivers tended to select slower driving speeds, larger vehicle spacings, and longer time headways when they were engaged in either hands-free or handheld phone conversations, suggesting possible risk compensatory behaviour. In addition, phone conversations while driving influenced car-following behaviour such that variability was increased in driving speeds, vehicle spacings, and acceleration and decelerations. To further investigate car-following behaviour of distracted drivers, driver time headways were modelled using Generalized Estimation Equation (GEE). After controlling for various exogenous factors, the model predicts an increase of 0.33s in time headway when a driver is engaged in hands-free phone conversation and a 0.75s increase for handheld phone conversation. The findings will improve the collective understanding of distraction on driving performance, in particular car following behaviour which is most critical in the determination of rear-end crashes.

    Injury prevention plays a key role in keeping children safe, but emerging research suggests that imposing too many restrictions on children's outdoor risky play hinders their development. We explore the relationship between child development, play, and conceptions of risk taking with the aim of informing child injury prevention. Generational trends indicate children's diminishing engagement in outdoor play is influenced by parental and societal concerns. We outline the importance of play as a necessary ingredient for healthy child development and review the evidence for arguments supporting the need for outdoor risky play, including: (1) children have a natural propensity towards risky play; and, (2) keeping children safe involves letting them take and manage risks. Literature from many disciplines supports the notion that safety efforts should be balanced with opportunities for child development through outdoor risky play. New avenues for investigation and action are emerging seeking optimal strategies for keeping children "as safe as necessary," not "as safe as possible." This paradigm shift represents a potential for epistemological growth as well as cross-disciplinary collaboration to foster optimal child development while preserving children's safety.

    The design, operation, management and regulation of risky, human-technical systems are considered as instances of problem solving systems. This paper presents a part of the problem solving perspective on nuclear power plant operation, both the engineered systems and the human role. The Three Mile Island accident is described as a ''fundamental surprise'' (the term is explained in a short paper at the end of the volume). However, when the accident investigation recommendations were being carried out, the accident became treated as a ''situational surprise''. The way in which behaviour science can contribute to nuclear safety is discussed, and the kinds of research needed is explored. Nuclear power plants are looked at as a problem solving system and human error and person-machine mismatches are considered. Automation and computer-based human performance aids are looked at. (UK)

    Full Text Available This study investigated the relevance of social settings as predictors of risky sexual behavior. In a young adult sample (n = 324, M age = 20.2 years, we examined the association between frequency of attendance at five different settings and frequency of engaging in four risky sexual behaviors (i.e., unprotected intercourse when not drunk or high, unprotected intercourse when drunk or high, casual sex when not drunk or high, casual sex when drunk or high. Predictive associations were examined using negative binomial regression, and all analyses controlled for frequency of recent alcohol use and age at first use of alcohol. Greater attendance at fraternity/sorority parties predicted more frequent intercourse for females in the not drunk or high and drunk or high contexts, and more frequent casual sex for males in the not drunk or high context. Greater attendance at large private parties predicted more frequent intercourse for females in the not drunk or high context. Greater attendance at bars without dance floors predicted more frequent intercourse for males in the drunk or high context. These findings highlight the importance of socializing habits in understanding risky sexual behavior.

    2009-01-01

    Graduated Driver Licensing (GDL) is a critical policy tool for potentially improving teenage driving while reducing teen accident exposure. While previous studies demonstrated that GDL reduces teenage involvement in fatal crashes, much remains unanswered. We explore the mechanisms through which GDL influences accident rates as well as its long term effectiveness on teen driving. In particular, we investigate; 1) whether GDL policies improve teenage driving behavior, or simply reduce teenage prevalence on the roads; 2) whether GDL exposed teens become better drivers in later years. We employ a unique data source, the State Data System, which contains all police reported accidents (fatal and non-fatal) during 1990–2005 for twelve states. We estimate a structural model that separately identifies GDL s effect on relative teenage prevalence and relative teenage riskiness. Identification of the model is driven by the relative numbers of crashes between two teenagers, two adults, or a teenager and an adult. We find that the GDL policies reduce the number of 15–17 year-old accidents by limiting the amount of teenage driving rather than by improving teenage driving. This prevalence reduction primarily occurs at night and stricter GDL policies, especially those with nighttime driving restrictions, are the most effective. Finally, we find that teen driving quality does not improve ex-post GDL exposure. PMID:19942310

    Full Text Available Substance abuse and risky sexual behavior have been identified as behaviors that can endanger adolescent psychosocial development. This study examined the relationship between methamphetamine (MAMP use and risky sexual behavior in adolescents. Risky sexual behavior was compared not only between MAMP users and non-users, but also between high-frequency and low-frequency MAMP users. We compared the sexual intercourse histories of 85 adolescents formally charged as MAMP users with those of 170 gender-matched adolescents with no record of MAMP use. MAMP usage characteristics were compared between users who had and those who had not experienced sexual intercourse. Previous sexual experience was more likely in MAMP users than in non-users. MAMP users were also more likely to have had a greater total number of sexual partners and were more likely to have had unplanned sex under the influence of alcohol. High-frequency MAMP use was associated with increased tendencies to engage in unprotected sex and to use MAMP before sexual intercourse. In general, the chance of sexual intercourse increased in proportion to frequency of MAMP use. Given the clear link between MAMP use and risky sexual behavior, risk-reduction programs directed at teen MAMP users are urgently needed.

    The purpose of this study was to use an ecological lens to explore gender differences in risky sexual behavior among urban adolescents exposed to violence. This was a secondary analysis of data from a larger behavioral intervention trial that targeted drinking behaviors among adolescents. Data from a total of 2,560 male and female urban adolescents between the ages of 14 and 21 were analyzed for personal, interpersonal, and community exposure to violence and risky sexual behavior. Violence has an impact on sexual risk. For females, carrying a weapon (p= 0.020) and feeling safe in intimate relationships (p= 0.029) were individual correlates of risky sexual behavior, while for males, race/ethnicity (p= 0.019) and being in a physical fight (p= 0.001) were significant correlates of risky sexual behavior. Risky sexual behavior among adolescents may lead to negative reproductive health outcomes. Nurse practitioners are in an excellent position to affect change in this population through their frequent contact with adolescents in a variety of community and school-based venues. Nurse practitioners are also well-prepared to identify at-risk adolescents and provide them with individualized care, education, and support. ©2012 The Author(s) Journal compilation ©2012 American Academy of Nurse Practitioners.

    Alcohol and other drug (AOD) use is increasingly recognised as having a direct and indirect effect on the transmission of human immunodeficiency virus (HIV). However, there is evidence to suggest that drug- and sex-related HIV risk-reduction interventions targeted at drug users within drug treatment centres or via community outreach efforts can lead to positive health outcomes. This study aimed to test whether a community-level intervention aimed at AOD users has an impact on risky AOD use and sexual risk behaviour. In 2007, in collaboration with a local non-governmental organisation (NGO) in Durban, an initiative was begun to implement a number of harm reduction strategies for injection and non-injection drug users. The NGO recruited peer outreach workers who received intensive initial training, which was followed by six-monthly monitoring and evaluation of their performance. Participants had to be 16 years of age or older, and self-reported alcohol and/or drug users. Peer outreach workers completed a face-to-face baseline questionnaire with participants which recorded risk behaviours and a risk-reduction plan was developed with participants which consisted of reducing injection (if applicable) and non-injection drug use and sex-related risks. Other components of the intervention included distribution of condoms, risk-reduction counselling, expanded access to HIV Testing Services, HIV/sexually transmitted infection care and treatment, and referrals to substance abuse treatment and social services. At follow-up, the baseline questionnaire was completed again and participants were also asked the frequency of reducing identified risk behaviours. Baseline information was collected from 138 drug users recruited into the study through community-based outreach, and who were subsequently followed up between 2010 and 2012. No injection drug users were reached. The data presented here are for first contact (baseline) and the final follow-up contact with the participants

    Public policy interventions designed to deter or prevent drunk driving depend, in part, on modifying beliefs concerning the riskiness, social acceptability and immorality of driving under the influence of alcohol. The current study examines the association of these beliefs with the incidence of alcohol-impaired driving. Interviews were conducted with 273 people with multiple driving under the influence (DUI) offenses. Data included self-reported frequency of driving after drinking in the past year, as well as measures of moral and prescriptive beliefs concerning alcohol-impaired driving (internal behavioral controls), perceived risks of criminal punishment and accidents associated with alcohol-impaired driving (external behavioral controls) and perceived peer group attitudes toward alcohol-impaired driving (social controls). Logit regression modeling showed significant, unique protective associations with behavioral control items in each category. Behavioral controls may protect against alcohol-impaired driving behavior even in a high-risk sample of repeat DUI offenders. Policy interventions designed to curtail drunk driving might seek to enhance these sorts of behavioral controls among DUI offenders.

    The purpose of this study was to investigate the role of age, gender, peer, family, and culture in adolescent risky sexual behavior for Cambodian and Laotian (Lao)/Mien youth. We obtained cross-sectional, in-home interview data including measures of individualism, collectivism, acculturation, risky sexual behavior, peer delinquency, parent engagement, and parent discipline from a sample of mostly second-generation Cambodian (n = 112) and Lao/Mien (n = 67) adolescents. Data were analyzed using step-wise, hierarchical multiple regressions. Peer delinquency and age (older) were significant predictors of risky sexual behavior in both groups. Parent discipline also significantly predicted risky sexual behavior, but only for Lao/Mien adolescents. Vertical and horizontal individualism were associated positively with risky sexual behavior for Cambodian youth whereas collectivism (horizontal) was associated negatively with risky sexual behavior for Lao/Mien youth. Acculturation was nonsignificant in both groups. In addition to age, parents, and peer groups, the findings suggest that culture also matters in risky sexual behavior, particularly for Cambodian and Laotian youth.

    Driving safety, impaired driving, and legislation to address these concerns remain important issues. It is imperative countermeasures be targeted toward the most appropriate groups. This paper explores the potential relationship between gender and driving attitudes toward safety issues and impaired-driving countermeasures. The data are from the 2007 Impaired Driving Survey commissioned by Transport Canada and Mothers Against Drunk Driving (MADD) Canada. The survey is a, stratified by region, telephone survey of 1,514 Canadian drivers 18years of age and older with a valid driver's license who had driven within the past 30days. The findings illustrate a consistent impact of gender on these issues. Other variables were also identified as relevant factors although less consistently. Current findings suggest that strategies for building support for interventions, or for changing risk perception/concern for risky driving behaviors should be tailored by gender to maximize the potential for behavior change. This information may assist program and policy developers through the identification of more or less receptive target groups. Future research directions are also presented.

    Although most countries state that fighting social intolerance against persons with HIV is part of their national HIV strategy, the impact of reducing intolerance on risky sexual behavior is largely unknown. In this paper, we estimate the effect of social intolerance against HIV+ persons on risky sexual behavior in rural Malawi using data from roughly 2000 respondents from the 2004 and 2006 waves of the Malawi Longitudinal Study of Families and Health (MLSFH). The effect of social intolerance on risky behavior is a priori ambiguous. On the one hand, higher social intolerance or stigma can lead people to disassociate from the stigmatized group and hence promote risky behavior. On the other hand, intolerance can be viewed as a social tax on being HIV+ and thus higher intolerance may reduce risky behavior. We find that a decrease in social intolerance is associated with a decrease in risky behavior, including fewer partners and a lower likelihood of having extra-marital relations. This effect is mainly driven by the impact of social intolerance on men. Overall the results suggests that reducing social intolerance might not only benefit the HIV positive but might also forestall the spread of HIV. Copyright © 2014 Elsevier Ltd. All rights reserved.

  11. What you may not see might slow you down anyway: masked images and driving.

    Directory of Open Access Journals (Sweden)

    Ben Lewis-Evans

    Full Text Available Many theories of driver behaviour suggest that unconscious or implicit emotions play a functional role in the shaping and control of behaviour. This has not been experimentally tested however. Therefore, in this study the effects of emotive masked images on driver behaviour were examined. While driving a simulator, participants were repeatedly exposed to negative or neutral emotionally laden target images that were sandwich masked by emotionally neutral images. These images were encountered across two different trials each of which consisted of 3-4 minutes of driving on a rural road. The results indicate an effect of the negative target images primarily in reducing the extent of familiarisation occurring between the first and second experimental drives. This is evident in a reduced decrease in heart rate and a reduced increase in high band heart rate variability and actual travelling speed from the first to second drives if the negative target image was presented in the second drive. In addition to these findings there was no clear effect of the target image on subjective ratings of effort or feelings of risk. There was however an effect of gender, with the majority of the effects found in the study being limited to the larger female dataset. These findings suggest that unconscious or implicit emotional stimuli may well influence driver behaviour without explicit awareness.

    Yvonne Groen

    Full Text Available OBJECTIVE: The aim of this review was to gain insight into the relationship between Attention deficit hyperactivity disorder (ADHD and risky performance in gambling tasks and to identify any potential alternate explanatory factors. METHODS: PsycINFO, PubMed, and Web of Knowledge were searched for relevant literature comparing individuals with ADHD to normal controls (NCs in relation to their risky performance on a gambling task. In total, fourteen studies in children/adolescents and eleven studies in adults were included in the review. RESULTS: Half of the studies looking at children/adolescents with ADHD found evidence that they run more risks on gambling tasks when compared to NCs. Only a minority of the studies on adults with ADHD reported aberrant risky behavior. The effect sizes ranged from small to large for both age groups and the outcome pattern did not differ between studies that applied an implicit or explicit gambling task. Two studies demonstrated that comorbid oppositional defiant disorder (ODD and conduct disorder (CD increased risky behavior in ADHD. Limited and/or inconsistent evidence was found that comorbid internalizing disorders (IDs, ADHD subtype, methylphenidate use, and different forms of reward influenced the outcomes. CONCLUSION: The evidence for increased risky performance of individuals with ADHD on gambling tasks is mixed, but is stronger for children/adolescents with ADHD than for adults with ADHD, which may point to developmental changes in reward and/or penalty sensitivity or a publication bias for positive findings in children/adolescents. The literature suggests that comorbid ODD/CD is a risk factor in ADHD for increased risky behavior. Comorbid IDs, ADHD subtype, methylphenidate use, and the form of reward received may affect risky performance in gambling tasks; however, these factors need further examination. Finally, the implications of the findings for ADHD models and the ecological validity of gambling tasks

    2012-12-01

    Existing studies suggest that individual and household level economic shocks affect the demand for and supply of risky sex. However, little evidence exists on the effects of an aggregate shock on equilibrium risky sexual behavior. This paper examines the effects of the early twenty-first century copper boom on risky sexual behavior in Zambian copper mining cities. The results suggest that the copper boom substantially reduced rates of transactional sex and multiple partnerships in copper mining cities. These effects were partly concentrated among young adults and copper boom induced in-migration to mining cities appears to have contributed to these reductions. Copyright © 2012.

    Full Text Available Research on the neural correlates of risk-related behaviors and personality traits has provided insight into mechanisms underlying both normal and pathological decision-making. Task-based neuroimaging studies implicate a distributed network of brain regions in risky decision-making. What remains to be understood are the interactions between these regions and their relation to individual differences in personality variables associated with real-world risk-taking.We employed resting state functional magnetic resonance imaging (R-fMRI and resting state functional connectivity (RSFC methods to investigate differences in the brain's intrinsic functional architecture associated with beliefs about the consequences of risky behavior. We obtained an individual measure of expected benefit from engaging in risky behavior, indicating a risk seeking or risk-averse personality, for each of 21 participants from whom we also collected a series of R-fMRI scans. The expected benefit scores were entered in statistical models assessing the RSFC of brain regions consistently implicated in both the evaluation of risk and reward, and cognitive control (i.e., orbitofrontal cortex, nucleus accumbens, lateral prefrontal cortex, dorsal anterior cingulate. We specifically focused on significant brain-behavior relationships that were stable across R-fMRI scans collected one year apart. Two stable expected benefit-RSFC relationships were observed: decreased expected benefit (increased risk-aversion was associated with 1 stronger positive functional connectivity between right inferior frontal gyrus (IFG and right insula, and 2 weaker negative functional connectivity between left nucleus accumbens and right parieto-occipital cortex.Task-based activation in the IFG and insula has been associated with risk-aversion, while activation in the nucleus accumbens and parietal cortex has been associated with both risk seeking and risk-averse tendencies.

    The lifetime of the control rod drives is studied. Their function is to take out or to pull in the control rods. The drive and the experiments carried out, are described. The analysis of the behaviour under operation, the drive inspections and surveyance, are also considered. The results are obtained from: the investigations performed on the fatigue strength of the 900 MW and 1300 MW drives, which allowed to deduce a low of wear and to identify the important aspects to be studied, the measurements of the dynamical stresses of mobile elements and a dynamical calculation model. The study leads to the conclusion that a probabilistic approach is needed for the fatigue damage analysis of some elements. Moreover, a systematic examination is also needed, to verify the agreement betwem the drives calculated aging values and the measured ones [fr

    During the last 25 years, prospect theory and its successor, cumulative prospect theory, replaced expected utility as the dominant descriptive theories of risky decision making. Although these models account for the original Allais paradoxes, 11 new paradoxes show where prospect theories lead to self-contradiction or systematic false predictions.…

    Full Text Available It is not known whether patients with juvenile myoclonic epilepsy (JME differ from healthy people in decision making under risk, i.e., when the decision-making context offers explicit information about options, probabilities, and consequences already from the beginning. In this study, we adopted the Game of Dice Task-Double to investigate decision making under risk in a group of 36 patients with JME (mean age 25.25/SD 5.29 years and a group of 38 healthy controls (mean age 26.03/SD 4.84 years. Participants also underwent a comprehensive neuropsychological assessment focused on frontal executive functions. Significant group differences were found in tests of psychomotor speed and divided attention, with the patients scoring lower than the controls. Importantly, patients made risky decisions more frequently than controls. In the patient group, poor decision making was associated with poor executive control, poor response inhibition, and a short interval since the last seizure episode. Executive control and response inhibition could predict 42% of variance in the frequency of risky decisions. This study indicates that patients with JME with poorer executive functions are more likely to make risky decisions than healthy controls. Decision making under risk is of major importance in every-day life, especially with regard to treatment decisions and adherence to long-term medical therapy. Since even a single disadvantageous decision may have long-lasting consequences, this finding is of high relevance.

    Objective: To provide size estimation and to determine risky behaviours and HIV prevalence among female sex workers in Pakistan, which has progressed from a low to concentrated level of HIV epidemic. Methods: A cross-sectional study (geographic mapping and integrated behavioural and biological survey-IBBS) was conducted between August 2005 to January 2006 in Karachi, Hyderabad and Sukkur. A detailed questionnaire and dry blood spot (DBS) specimen for HIV testing were collected by trained interviewers after informed consent. The study was ethically approved by review boards in Canada and Pakistan. Results: About 14,900 female sex workers were estimated to be functional in Sindh. A total of 1158 of them were interviewed for the study. Average age of sex workers was 27.4+- 6.7 years, and the majority 787 (67.9%) were married, and uneducated 764 (65.9%). Sindhi (26.4%) was the predominant ethnicity. Mean number of paid clients was 2.1+-1.2. Three workers were confirmed HIV positive (0.75%, 95 percent CI 0.2-2.2%) from Karachi. Condom use at last sexual act was highest (68%) among brothel-based workers from Karachi, and the lowest in Sukkur where only 1.3% street-based workers reported using a condom at last sexual act. Overall use of illicit drugs through injections was negligible. Conclusion: HIV prevalence among female sex workers in Sindh, Pakistan is low but risky behaviours are present. Well organised service delivery programmes can help promoting safer practices. (author)

    Adolescent ethanol exposure increases risky choice and alters corticotropin releasing factor (CRF) systems in adulthood. The impact of stress on risky choice after adolescent intermittent ethanol (AIE) exposure is not known. We investigated time-specific effects of AIE vapor exposure during early adolescence on risky choice after stress or no stress in adulthood. Male Wistar rats were exposed to air or AIE vapor on postnatal days 28-42 (adolescence) and were exposed to 10days of social defeat or no stress on postnatal days 172-181 (adulthood). Risky choice was assessed in the probability discounting task under baseline conditions and after days 1 and 10 of social defeat. CRF and CRF receptor 1 (CRFR1) mRNA levels were assessed in the prefrontal cortex (PFC) and the central nucleus of the amygdala (CeA) 24h post-stress to evaluate persistent effects of stress on the brain. AIE exposure had no effect on risky choice either at baseline or after social defeat. Additionally, neither acute nor chronic social defeat affected risky choice in air-exposed rats. In the PFC, chronic social defeat selectively decreased CRF mRNA levels in air-exposed rats and increased CRFR1 mRNA levels in all rats. AIE exposure increased CRF mRNA levels in the CeA with no effect of social stress. Our results indicate no effect of ethanol exposure via vapor during early adolescence on risky choice, while our previous findings indicated that AIE exposure via gavage affected risky choice. Both AIE exposure and social defeat altered CRF and CRFR1 mRNA levels in the brain. Copyright © 2016 Elsevier B.V. All rights reserved.

    In party circuits dexamphetamine is frequently used in combination with alcohol. It is hypothesized that co-administration of dexamphetamine to alcohol might reduce the sedative effects of alcohol, but may potentiate risk-taking behaviour. The study was aimed at assessing the effects of alcohol, dexamphetamine and the combination of both on simulated driving and cognitive performance. Eighteen subjects participated in a randomized, crossover, placebo-controlled study employing four conditions: 10 mg dexamphetamine, 0.8 g/kg alcohol, 10 mg dexamphetamine + 0.8 g/kg alcohol, and placebo. Fundamental driving skills and risk-taking behaviour were assessed in a driving simulator. Subjects also completed vigilance and divided attention tasks, and subjective ratings. Mean BAC levels during simulated driving were between 0.91‰ and 0.64‰. Subjects using alcohol showed a significantly larger mean standard deviation of lateral position and shorter accepted gap time and distance. Use of alcohol or dexamphetamine + alcohol was associated with a higher frequency of red light running and collisions than the dexamphetamine or placebo conditions. Performance of vigilance and divided attention tasks was significantly impaired in the alcohol condition and, to a lesser degree, in the dexamphetamine + alcohol condition. Single doses of 0.8 g/kg alcohol increased risk-taking behaviours and impaired tracking, attention and reaction time during a 3-h period after drinking when BACs declined from 0.9 to 0.2 mg/ml. The stimulatory effects of co-administration of dexamphetamine 10 mg were not sufficient to overcome the impairing effects of alcohol on skills related to driving.

    2007-01-01

    The purpose of this investigation was to identify risky driving behaviors and dispositions that distinguish drivers who use a cell phone while operating a motor vehicle from non-cell phone using drivers. Annual telephone surveys were used to identify drivers who reported using a cell phone while driving in the last month (n=1803) and were compared to those who said they did not use cell phones while driving (n=1578). Cell phone using drivers were more likely to report driving while drowsy, going 20 mph over the speed limit, driving aggressively, running a stop sign or red light, and driving after having had several drinks. They were also more likely to have had a prior history of citation and crash involvement than non-cell phone using drivers. Cell phone using drivers also reported they were less careful and more in a hurry when they drive than non-cell phone using drivers. Cell phone using drivers report engaging in many behaviors that place them at risk for a traffic crash, independent of the specific driving impairments that cell phone usage may produce. Strategies that combine coordinated and sustained enforcement activities along with widespread public awareness campaigns hold promise as effective countermeasures for these drivers, who resemble aggressive drivers in many respects.

    Accurate self-assessment of skill is important because it creates an appropriate level of confidence and hence behaviour. Inaccurate self-assessment of driving ability has been linked to reckless driving and accidents. Inaccurate self-assessment of driving skills may be a contributing factor...... to the over-representation of young male drivers in accident statistics. Most previous research on self-assessment of driving skills did not compare self-reported skills to objectively measured driving skills, so the aims of this study were: (1) to test the accuracy of young male drivers’ self......-assessments of specific driving skills by comparing them with performance in a driving simulator; (2) to test whether self-assessment accuracy varied with driving skill, driving experience and sensation-seeking propensity. We found that young male drivers’ self-assessments were inconsistent with their driving performance...

    To determine (i) whether the strength of Australian alcohol control policy in three domains (youth access, trading hours and drink driving) changed during the 2000s; and (ii) estimate associations between these policies and adolescent drinking after adjusting for television alcohol advertising exposures, alcohol outlet density, alcohol price changes, exposure to negative articles about alcohol in daily newspapers and adult drinking prevalence. Repeated cross-sectional surveys conducted triennially from 2002 to 2011. Multi-level modelling examined the association between alcohol control policies and drinking prevalence after adjusting for covariates. Four Australian capital cities between 2002 and 2011. Students aged 12-17 years participating in a triennial national representative school-based survey (sample size range/survey: 9805-13 119). Outcome measures were: past month drinking and risky drinking (5+ drinks on a day) in the past 7 days. Policy strength in each of three domains (youth access, trading hours, drink-driving) were the key predictor variables. Covariates included: past 3-month television alcohol and alcohol-control advertising, alcohol outlet density, alcohol price change, negatively framed newspaper alcohol articles, adult drinking prevalence and student demographic characteristics. During the study period, the strength of youth access policies increased by 10%, trading hours policies by 14% and drink-driving policies by 58%. Past-month and risky drinking prevalence decreased (e.g. past-month: 2002: 47.4% to 2011: 26.3%). Multivariable analyses that included all policy variables and adjusted for year, student and other covariates showed past-month drinking to be associated inversely with stronger trading hours policies [odds ratio (OR) = 0.80, 95% confidence interval (CI) = 0.69, 0.94], but not youth access (OR = 0.92 95% CI = 0.81, 1.04) or drink-driving (OR = 1.00, 95% CI = 0.93, 1.09).

    The objective of this prospective one-year follow-up study was to explore the associations between self-regulatory mechanisms and neuropsychological tests as well as baseline and follow-up ratings of driver behaviour. The participants were a cohort of subjects with stroke and traumatic brain injury (TBI) who were found fit to drive after a multi-disciplinary driver assessment (baseline). Baseline measures included neuropsychological tests and ratings of self-regulatory mechanisms, i.e., executive functions (Behavior Rating Inventory of Executive Function-Adult Version; BRIEF-A) and impulsive personality traits (UPPS Impulsive Behavior Scale). The participants rated pre-injury driving behaviour on the Driver Behaviour Qestionnaire (DBQ) retrospectively at baseline and after one year of post-injury driving (follow-up). Better performance on neuropsychological tests was significantly associated with more post-injury DBQ Violations. The BRIEF-A main indexes were significantly associated with baseline and follow-up ratings of DBQ Mistakes and follow-up DBQ Inattention. UPPS (lack of) Perseverance was significantly associated with baseline DBQ Inattention, whereas UPPS Urgency was significantly associated with baseline DBQ Inexperience and post-injury DBQ Mistakes. There were no significant changes in DBQ ratings from baseline (pre-injury) to follow-up (post-injury). It was concluded that neuropsychological functioning and self-regulatory mechanisms are related to driver behaviour. Some aspects of driver behaviour do not necessarily change after brain injury, reflecting the influence of premorbid driving behaviour or impaired awareness of deficits on post-injury driving behaviour. Further evidence is required to predict the role of self-regulatory mechanisms on driver behaviour and crashes or near misses.

    There is a view that young people presenting with an animal cruelty and firesetting combination represent a uniquely risky group, but prior work has relied on samples with insufficient power. What is the prevalence of the co-occurrence of animal cruelty and firesetting behaviour among young delinquents? What other features correlate with this? We measured the prevalence of animal cruelty and firesetting among 292,649 juvenile offenders and used rare events logistic regression to examine demographic, criminal, mental health and family histories as correlates. The prevalence of animal cruelty was 0.59%, accounting for 1732 young people, and of firesetting 1.56% (n = 4553). The co-occurrence of these behaviours was rare: 0.17% (n = 498), but approximately twice that expected by chance based on the prevalence of each behaviour individually (0.59% × 1.56% = 0.009%). Rates were higher in males, older youths and Whites. Among historical variables, criminal history was the strongest correlate, followed by mental health problems, then familial and individual indicators. As only male gender and being a victim of sexual abuse increased the odds of evidencing both animal cruelty and firesetting behaviour substantially above the odds for each behaviour individually, there thus appears to be little that is unique to the co-occurrence. Our findings suggest that sensitivity to the occurrence of each is the best way forward, with rather familiar assessments and interventions offering some hope of reducing these seriously damaging behaviours.

  14. Does compulsive behaviour in Anorexia Nervosa resemble an addiction? A qualitative investigation

    Directory of Open Access Journals (Sweden)

    Lauren Rose Godier

    2015-10-01

    Full Text Available The characteristic relentless self-starvation behaviour seen in Anorexia Nervosa (AN has been described as evidence of compulsivity, with increasing suggestion of parallels with addictive behaviour. This study used a thematic qualitative analysis to investigate the parallels between compulsive behaviour in AN and Substance Use Disorders (SUD. Forty individuals currently suffering from AN completed an online questionnaire reflecting on their experience of compulsive behaviour in AN. Eight main themes emerged from thematic qualitative analysis; compulsivity as central to AN, impaired control, escalating compulsions, emotional triggers, negative reactions, detrimental continuation of behaviour, functional impairment, and role in recovery. These results suggested that individuals with AN view the compulsive nature of their behaviour as central to the maintenance of their disorder, and as a significant barrier to recovery. The themes that emerged also showed parallels with the DSM-V criteria for Substance Use Disorders (SUDs, mapping onto the four groups of criteria (impaired control, social impairment, risky use of substance, pharmacological criteria. These results emphasise the need for further research to explore the possible parallels in behavioural and neural underpinnings of compulsivity in AN and SUDs, which may inform novel treatment avenues for AN.

    Full Text Available This study (1 reports frequency rates of mutually exclusive traditional, cyber and combined (both traditional and cyber bullying roles; and (2 investigates whether adolescents belonging to particular bullying roles show higher levels of involvement in risky online activities (Compulsive Internet Use (CIU, online grooming victimization, and sexting and risky offline activities (bad behavior in school, drinking alcohol and truancy than non-involved adolescents. The sample comprised self-reports of 1928 German, Dutch and Thai adolescents (Age = 12–18; M = 14.52; SD = 1.6. The results revealed age, sex and country differences in bullying frequency rates. CIU, sending of sexts and risky offline activities were most strongly associated with combined bully-victims. The receiving of sexts was most strongly associated with combined bullies; and online grooming victimization was most strongly related to cyber bully-victims. Another important finding is that the associations between risky offline activities and combined bullying are stronger than for traditional and cyber bullying. The findings contribute to better understanding of the associations between varying bullying roles and risky online and offline activities among adolescents. In sum, the results underscore the need to promote life skills rather than adopting more conventional approaches, which focus almost exclusively on reduction of risks.

  16. Everything's better in moderation: young women's gender role attitudes and risky sexual behavior.

    Leech, Tamara G J

    2010-05-01

    This study examines the association between gender role attitudes and risky sexual behavior among young women. Previous studies have posed seemingly contradictory arguments: that either traditional attitudes or egalitarian attitudes are associated with riskier behavior. Data are based on the children of the National Longitudinal Survey of Youth, representing 520 sexually active 18-19-year-old women. Propensity radius matching was used to assess differences in rates of multiple sexual partners and sex outside of a committed relationship. Relative to moderate gender role attitudes, both egalitarian gender role attitudes and traditional gender role attitudes are associated with higher rates of risky sexual behavior. Both women with egalitarian role attitudes and those with traditional role attitudes have about a 10% higher prevalence of risky behavior compared to women with more moderate gender role attitudes. Existing, seemingly contradictory contentions about the relationship between gender role attitudes and risky sexual behavior may be more coherent than they seem. By shifting focus from risk to protection, the results suggest that moderate gender role attitudes are protective against risky sexual behavior. Future studies should investigate the causal mechanisms and intervention implications of this protective relationship. Copyright 2010 Society for Adolescent Medicine. Published by Elsevier Inc.

    Risky sexual behavior, particularly among adolescents, continues to be a major source of concern. In order to develop effective education and prevention programs, there is a need for research that identifies the antecedents of such behavior. This study investigated the mediators that link parenting experiences during early adolescence to subsequent risky sexual behaviors among a diverse sample of African American youth (N = 629, 55 % female). While there is ample evidence that parenting practices (e.g., supportive parenting, harsh parenting, parental management) are antecedent to risky sexual behavior, few studies have examined whether one approach to parenting is more strongly related to risky sex than others. Using a developmental approach, the current study focused on factors associated with six theories of risky sexual behavior. While past research has provided support for all of the theories, few studies have assessed the relative contribution of each while controlling for the processes proposed by the others. The current study addresses these gaps in the literature and reports results separately by gender. Longitudinal analyses using structural equation modeling revealed that the mediating mechanisms associated with social learning and attachment theories were significantly related to the risky sexual behavior of males and females. Additionally, there was support for social control and self-control theories only for females and for life history theory only for males. We did not find support for problem behavior theory, a perspective that dominates the risky sex literature, after controlling for the factors associated with the other theories. Finally, supportive parenting emerged as the parenting behavior most influential with regard to adolescents' risky sexual behavior. These results provide insight regarding efficacious approaches to education and preventative programs designed to reduce risky sexual behaviors among adolescents.

    Opioid overdose and other related harms are a major source of morbidity and mortality among US Veterans, in part due to high-risk opioid prescribing. We sought to determine whether having multiple sources of payment for opioids-as a marker for out-of-system access-is associated with risky opioid therapy among veterans. Cross-sectional study examining the association between multiple sources of payment and risky opioid therapy among all individuals with Veterans Health Administration (VHA) payment for opioid analgesic prescriptions in Kentucky during fiscal year 2014-2015. Source of payment categories: (1) VHA only source of payment (sole source); (2) sources of payment were VHA and at least 1 cash payment [VHA+cash payment(s)] whether or not there was a third source of payment; and (3) at least one other noncash source: Medicare, Medicaid, or private insurance [VHA+noncash source(s)]. Our outcomes were 2 risky opioid therapies: combination opioid/benzodiazepine therapy and high-dose opioid therapy, defined as morphine equivalent daily dose ≥90 mg. Of the 14,795 individuals in the analytic sample, there were 81.9% in the sole source category, 6.6% in the VHA+cash payment(s) category, and 11.5% in the VHA+noncash source(s) category. In logistic regression, controlling for age and sex, persons with multiple payment sources had significantly higher odds of each risky opioid therapy, with those in the VHA+cash having significantly higher odds than those in the VHA+noncash source(s) group. Prescribers should examine the prescription monitoring program as multiple payment sources increase the odds of risky opioid therapy.

    We developed a behavioral task in rats to assess the influence of risk of punishment on decision making. Male Long-Evans rats were given choices between pressing a lever to obtain a small, 'safe' food reward and a large food reward associated with risk of punishment (footshock). Each test session consisted of 5 blocks of 10 choice trials, with punishment risk increasing with each consecutive block (0, 25, 50, 75, 100%). Preference for the large, 'risky' reward declined with both increased probability and increased magnitude of punishment, and reward choice was not affected by the level of satiation or the order of risk presentation. Performance in this risky decision-making task was correlated with the degree to which the rats discounted the value of probabilistic rewards, but not delayed rewards. Finally, the acute effects of different doses of amphetamine and cocaine on risky decision making were assessed. Systemic amphetamine administration caused a dose-dependent decrease in choice of the large risky reward (ie, it made rats more risk averse). Cocaine did not cause a shift in reward choice, but instead impaired the rats' sensitivity to changes in punishment risk. These results should prove useful for investigating neuropsychiatric disorders in which risk taking is a prominent feature, such as attention deficit/hyperactivity disorder and addiction.

  3. Physical Health Risk Behaviours in Young People with Mental Illness.

    Comorbid physical health conditions, commonly associated with mental illness, contribute to increased morbidity and reduced life expectancy. The trajectory to poorer health begins with the onset of mental illness. For young people with mental illness, health risk behaviours and poor physical health can progress to adulthood with long-term detrimental impacts. Using a cross-sectional survey design, self-reported health risk behaviours were gathered from 56 young (16-25 years) Australians who had been hospitalised for mental illness and taking psychotropic medication. Smoking, alcohol use, minimal physical activity, and lack of primary health care were evident. While these behaviours are typical of many young people, those with mental illness have substantially increased vulnerability to poor health and reduced life expectancy. Priority needs to be given to targeted health promotion strategies for young people with mental illness to modify their risky long-term health behaviours and improve morbidity and mortality outcomes. Nurses in mental health settings play a vital role in promoting young peoples' well-being and preventing poorer physical health outcomes. Implementation of a cardiometabolic health nurse role in inpatient settings for young people with mental illness could facilitate prevention and early intervention for health risk behaviours.

    To ease some of the major problems in the field of mobility and transport a change in travel and driving behaviour is needed. At this moment, too many travellers use the car and drive at the same moment in time. In order to change travel behaviour various measures can be taken. However, often one

    The human thermoregulatory system relies primarily on behavioural adaptation and secondarily on autonomic and endocrine responses for thermal homeostasis. This is because autonomic and endocrine responses have a limited capacity in preventing hyper/hypothermia in extreme environments. Until recently, the neuroanatomy of behavioural thermoregulation as well as the neuroanatomic substrate of the various thermoregulatory behaviours remained largely unknown. However, this situation has changed in recent years as behavioural thermoregulation has become a topic of considerable attention. The present review evaluates the current knowledge on behavioural thermoregulation in order to summarize the present state-of-the-art and to point towards future research directions. Findings on the fundamental distinction between thermal (dis)comfort and sensation are reviewed showing that the former drives behaviour while the latter initiates autonomic thermoregulation. Moreover, the thermosensitive neurons and thermoeffector functions of behavioural thermoregulation are presented and analysed in a detailed discussion.

    Isotropic and anisotropic Oslo models (IOM and AOM) under a bulk driving mechanism have been investigated. We apply the moment analysis to evaluate critical exponents and the finite size scaling method to consistently test the obtained results. We find that both types of Oslo model have different critical behaviour. However, the critical exponents are the same for deterministic and random IOMs, and are independent of the strength of the anisotropy for the AOM. In contrast to a boundary driving mechanism, we find that the critical exponents depend crucially on the driving mechanism for the IOM, and are independent of the driving mechanism for the AOM.

    Yuan-Wei Yao

    Full Text Available Individuals with Internet gaming disorder (IGD tend to exhibit disadvantageous risky decision-making not only in their real life but also in laboratory tasks. Decision-making is a complex multifaceted function and different cognitive processes are involved in decision-making for gains and losses. However, the relationship between impaired decision-making and gain versus loss processing in the context of IGD is poorly understood. The main aim of the present study was to separately evaluate decision-making for risky gains and losses among college students with IGD using the Cups task. Additionally, we further examined the effects of outcome magnitude and probability level on decision-making related to risky gains and losses respectively. Sixty college students with IGD and 42 matched healthy controls (HCs participated. Results indicated that IGD subjects exhibited generally greater risk taking tendencies than HCs. In comparison to HCs, IGD subjects made more disadvantageous risky choices in the loss domain (but not in the gain domain. Follow-up analyses indicated that the impairment was associated to insensitivity to changes in outcome magnitude and probability level for risky losses among IGD subjects. In addition, higher Internet addiction severity scores were associated with percentage of disadvantageous risky options in the loss domain. These findings emphasize the effect of insensitivity to losses on disadvantageous decisions under risk in the context of IGD, which has implications for future intervention studies.

    2011-06-21

    This theoretical article views children's risky play from an evolutionary perspective, addressing specific evolutionary functions and especially the anti-phobic effects of risky play. According to the non-associative theory, a contemporary approach to the etiology of anxiety, children develop fears of certain stimuli (e.g., heights and strangers) that protect them from situations they are not mature enough to cope with, naturally through infancy. Risky play is a set of motivated behaviors that both provide the child with an exhilarating positive emotion and expose the child to the stimuli they previously have feared. As the child's coping skills improve, these situations and stimuli may be mastered and no longer be feared. Thus fear caused by maturational and age relevant natural inhibition is reduced as the child experiences a motivating thrilling activation, while learning to master age adequate challenges. It is concluded that risky play may have evolved due to this anti-phobic effect in normal child development, and it is suggested that we may observe an increased neuroticism or psychopathology in society if children are hindered from partaking in age adequate risky play.

    Decision making is a multifaceted process, consisting of several distinct phases that likely require different cognitive operations. Previous work showed that the basolateral amygdala (BLA) is a critical substrate for decision making involving risk of punishment; however, it is unclear how the BLA is recruited at different stages of the decision process. To this end, the current study used optogenetics to inhibit the BLA during specific task phases in a model of risky decision making (risky decision-making task) in which rats choose between a small, "safe" reward and a large reward accompanied by varying probabilities of footshock punishment. Male Long-Evans rats received intra-BLA microinjections of viral vectors carrying either halorhodopsin (eNpHR3.0-mCherry) or mCherry alone (control) followed by optic fiber implants and were trained in the risky decision-making task. Laser delivery during the task occurred during intertrial interval, deliberation, or reward outcome phases, the latter of which was further divided into the three possible outcomes (small, safe; large, unpunished; large, punished). Inhibition of the BLA selectively during the deliberation phase decreased choice of the large, risky outcome (decreased risky choice). In contrast, BLA inhibition selectively during delivery of the large, punished outcome increased risky choice. Inhibition had no effect during the other phases, nor did laser delivery affect performance in control rats. Collectively, these data indicate that the BLA can either inhibit or promote choice of risky options, depending on the phase of the decision process in which it is active. SIGNIFICANCE STATEMENT To date, most behavioral neuroscience research on neural mechanisms of decision making has used techniques that preclude assessment of distinct phases of the decision process. Here we show that optogenetic inhibition of the BLA has opposite effects on choice behavior in a rat model of risky decision making, depending on the phase

  15. Risky Play and Children’s Safety: Balancing Priorities for Optimal Child Development

    2012-08-01

    Full Text Available Injury prevention plays a key role in keeping children safe, but emerging research suggests that imposing too many restrictions on children’s outdoor risky play hinders their development. We explore the relationship between child development, play, and conceptions of risk taking with the aim of informing child injury prevention. Generational trends indicate children’s diminishing engagement in outdoor play is influenced by parental and societal concerns. We outline the importance of play as a necessary ingredient for healthy child development and review the evidence for arguments supporting the need for outdoor risky play, including: (1 children have a natural propensity towards risky play; and, (2 keeping children safe involves letting them take and manage risks. Literature from many disciplines supports the notion that safety efforts should be balanced with opportunities for child development through outdoor risky play. New avenues for investigation and action are emerging seeking optimal strategies for keeping children “as safe as necessary,” not “as safe as possible.” This paradigm shift represents a potential for epistemological growth as well as cross-disciplinary collaboration to foster optimal child development while preserving children’s safety.

    Rates of sexually transmitted infections (STIs) among adolescents are on the rise. The majority of adolescents who contract STIs do so through risky sexual behavior. Previous literature has identified multiple correlates of risky sexual behaviors among adolescents, including physical and sexual victimization, mental health concerns, and substance use. Few studies, however, have examined these relationships together in a comprehensive model. The primary purpose of this study was to examine whether relationship violence was related to risky sexual behavior, and whether mental health symptoms and substance use mediated this relationship. A cross-sectional design was used, and adolescent females (N = 179), recruited from social service agencies, were 18.9 years old on average and were 37.2% White, 19.3% Black, 37.9% multiracial, and 5.6% other. Regression results revealed that females who were physically assaulted and sexually victimized by their intimate partners did engage in more sex without condoms. Mediational analyses indicated that PTSD symptoms significantly influenced the relationship between (1) physical assault and risky sexual behavior and (2) sexual victimization and risky sexual behavior. Contrary to expectations, PTSD may act to reduce risk perhaps by reducing interest in sex. It is important to address victimization, PTSD, and sexual risk in young women. More work is needed to understand these complex relationships using longitudinal designs. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  19. Mobile device use while driving--United States and seven European countries, 2011.

    2013-03-15

    Road traffic crashes are a global public health problem, contributing to an estimated 1.3 million deaths annually. Known risk factors for road traffic crashes and related injuries and deaths include speed, alcohol, nonuse of restraints, and nonuse of helmets. More recently, driver distraction has become an emerging concern. To assess the prevalence of mobile device use while driving in Belgium, France, Germany, the Netherlands, Portugal, Spain, the United Kingdom (UK), and the United States, CDC analyzed data from the 2011 EuroPNStyles and HealthStyles surveys. Prevalence estimates for self-reported talking on a cell phone while driving and reading or sending text or e-mail messages while driving were calculated. This report describes the results of that analysis, which indicated that, among drivers ages 18-64 years, the prevalence of talking on a cell phone while driving at least once in the past 30 days ranged from 21% in the UK to 69% in the United States, and the prevalence of drivers who had read or sent text or e-mail messages while driving at least once in the past 30 days ranged from 15% in Spain to 31% in Portugal and the United States. Lessons learned from successful road safety efforts aimed at reducing other risky driving behaviors, such as seat belt nonuse and alcohol-impaired driving, could be helpful to the United States and other countries in addressing this issue. Strategies such as legislation combined with high-visibility enforcement and public education campaigns deserve further research to determine their effectiveness in reducing mobile device use while driving. Additionally, the role of emerging vehicle and mobile communication technologies in reducing distracted driving-related crashes should be explored.

    In today's world, more adolescents are using the Internet as an avenue for social communication and a source of information and to experiment with risky online behaviors. To better understand how early adolescents are using the Internet, a study was undertaken to more clearly identify online use and online risky behaviors and to describe any online relationships with strangers middle-school students may be participating in. This exploratory study adapted the Youth Internet Safety Survey of Finkelhor et al to identify the usage and characteristics of online youth, solicitation of youth, and risky behaviors. Four hundred and four students, with a mean age of 12 years, were recruited from public and parochial schools located in the Northeast. Findings from this study indicate that of a total sample of 404 middle-school students, a small grouping (n = 59; 14.6%) are beginning risky online communication behaviors with strangers. Students who communicated online with strangers were older and had higher rates of posting personal information, risky online behaviors, and stealing. The majority of this group (84%) met offline with the online stranger, and three students reported having been assaulted. Findings suggest that early adolescents are beginning risky online and offline behaviors. Understanding their experiences is important since they highlight how middle-school students are undertaking risks in a new environment that many adults and parents do not fully understand. Clinicians, educators, healthcare providers, and other professionals need to be informed of Internet behaviors in order to assess for risk, to make referrals, to intervene, and to educate.

    To describe levels of risky sexual behaviour, HIV testing and HIV knowledge among men and women in Guatemala by ethnic group and to identify adjusted associations between ethnicity and these outcomes. Data on 16,205 women aged 15-49 and 6822 men aged 15-59 from the 2008-2009 Encuesta Nacional de Salud Materno Infantil were used to describe ethnic group differences in sexual behaviour, HIV knowledge and testing. We then controlled for age, education, wealth and other socio-demographic factors in a multivariate logistic regression model to examine the effects of ethnicity on outcomes related to age at sexual debut, number of lifetime sex partners, comprehensive HIV knowledge, HIV testing and lifetime sex worker patronage (men only). The data show low levels of risky sexual behaviour and low levels of HIV knowledge among indigenous women and men, compared to other respondents. Controlling for demographic factors, indigenous women were more likely than other women never to have been tested for HIV and to lack comprehensive HIV knowledge. They were less likely to report early sexual debut and three or more lifetime sexual partners. Indigenous men were more likely than other men to lack comprehensive HIV knowledge and demonstrated lower odds of early sexual debut, 10 or more lifetime sexual partners and sex worker patronage. The Mayan indigenous population in Guatemala, while broadly socially vulnerable, does not appear to be at elevated risk for HIV based on this analysis of selected risk factors. Nonetheless, low rates of HIV knowledge and testing may be cause for concern. Programmes working in indigenous communities should focus on HIV education and reducing barriers to testing. Further research into the factors that underlie ethnic self-identity and perceived ethnicity could help clarify the relative significance of these measures for HIV risk and other health outcomes.

  2. Young drivers and their cars: Safe and sound or the perfect storm?

    Consistent with the experiences in high-income countries, young drivers remain overrepresented in road trauma statistics in low- and middle-income countries. This article pursues the emerging interest of approaching the young driver problem from a systems thinking perspective in order to design and deliver robust countermeasures. Specifically, the focus of this paper is the cars driven by young drivers. The study of vehicles' characteristics and their interaction with driving behaviour is, more often than not, considered a minor concern when developing countermeasures in young drivers' safety not only in developed nations, but especially in developing nations. Participants completed an online survey containing the 44-item Behaviour of Young Novice Drivers Scale Spanish version (BYNDS-Sp), in addition to providing information regarding their vehicle, any crash involvement, and driving offences. Based on the vehicle model information, the assessment of vehicle safety was conducted for three safety programs (ANCAP, Latin NCAP, U.S. NCAP). Young drivers in Colombia reported a breadth of risky driving behaviours worth targeting in broader interventions. For example, interventions can target speeding, particularly as three quarters of the participants drove small-medium cars associated with poorer road safety outcomes. Moreover, risky driving exposure was highly prevalent amongst the young driver participants, demonstrating the need for them to be driving the safest vehicles possible. It is noteworthy that few cars were able to be assessed by the Latin NCAP (with half of the cars rated having only 0-2 star ratings), and that there was considerable discrepancy between ANCAP, U.S. NCAP, and Latin NCAP ratings. The need for system-wide strategies to increase young driver road safety-such as improved vehicle safety-is vital to improve road safety outcomes in jurisdictions such as Colombia. Such improvements may also require systemic changes such as enhanced vehicle safety

    Motivation models in driving behaviour postulate that driver motives and emotional states dictate risk tolerance under various traffic conditions. The present study used time and driver performance-based payment systems to manipulate motivation and risk-taking behaviour. Ten participants drove to a predefined location in a simulated driving environment. Traffic patterns (density and velocity) were manipulated to cause driver behaviour adjustments due to the need to conform with the social norms of the roadway. The driving environment complexity was investigated as a mediating factor in risk tolerance. Results revealed the performance-based payment system to closely relate to risk-taking behaviour as compared with the time-based payment system. Drivers conformed with social norms associated with specific traffic patterns. Higher roadway complexity led to a more conservative safety margins and speeds. This research contributes to the further development of motivational models of driver behaviour. This study provides empirical justification for two motivation factors in driver risk-taking decisions, including compliance with social norm and emotions triggered by incentives. Environment complexity was identified as a mediating factor in motivational behaviour model. This study also recommended safety margin measures sensitive to changes in driver risk tolerance.

    The objective of this study was to describe self-reported high alcohol use at each of the 3 licensing stages of graduated driver licensing and its relationship to drink-driving behaviors, intentional risky driving, aggressive driving, alcohol traffic offenses, non-alcohol traffic offenses, and traffic crashes. The New Zealand Drivers Study (NZDS) is a multistage, prospective cohort study of newly licensed drivers interviewed at all 3 stages of the graduated driver licensing system: learner (baseline), restricted (intermediate), and full license. At each stage, alcohol use was self-reported using the Alcohol Use Disorders Identification Test (AUDIT-C), with high alcohol use defined as a score of ≥4 for males and ≥3 for females. Sociodemographic and personality data were obtained at the baseline interview. Alcohol-related, intentional risky, and aggressive driving behaviors were self-reported following each license stage. Traffic crashes and offenses were identified from police records. Crashes were also self-reported. Twenty-six percent (n = 397) reported no high alcohol use, 22% at one license stage, 30% at 2 stages, and 22% at 3 stages. Poisson regression results (unadjusted and adjusted) showed that the number of stages where high alcohol use was reported was significantly associated with each of the outcomes. For most outcomes, and especially the alcohol-involved outcomes, the relative risk increased with the number of stages of high alcohol use. We found that high alcohol use was common among young newly licensed drivers and those who repeatedly reported high alcohol use were at a significantly higher risk of unsafe driving behaviors. Recently introduced zero blood alcohol concentration (BAC) should help to address this problem, but other strategies are required to target persistent offenders.

In this paper we extend this notion to examine the role that information at different (particularly cardinal orientations might play in a number of established phenomena each a behavioural “signature” of face processing. In particular we consider (a the face inversion effect (FIE, (b the facial identity after-effect, (c face-matching across viewpoint, and (d interactive, so-called holistic, processing of face parts. We report that filtering faces to remove all but the horizontal information largely preserves these effects but conversely, retaining vertical information generally diminishes or abolishes them. We conclude that preferential processing of horizontal information is a central feature of human face processing that supports many of the behavioural signatures of this critical visual operation.

    Understanding the role of emotional states is critical for predicting the kind of decisions people will make in risky situations. Currently, there is little understanding as to how emotion influences decision-making in situations such as terrorist attacks, natural disasters, pandemics, and combat. To help address this, we used behavioral and neuroimaging methods to examine how emotion states and traits influence decisions. Specifically, this study used a wheel of fortune behavioral task and functional magnetic resonance imaging (fMRI) to examine the effects of emotional states and traits on decision-making pertaining to the degree of risk people are willing to make in specific situations. The behavioral results are reported here. The neural data requires additional time to analyze and will be reported at a future date. Biases caused by emotion states and traits were found regarding the likelihood of making risky decisions. The behavioral results will help provide a solid empirical foundation for modeling the effects of emotion on decision in risky situations.

    Full Text Available The study reported in this manuscript used a mixture item response model with data from the Youth Risk Behavior Survey 2009 (N = 16,410 to identify subtypes of adolescents at-risk for engaging in unhealthy behaviors, and to find individual survey items that were most effective at identifying such students within each subtype. The goal of the manuscript is twofold: 1 To demonstrate the utility of the mixture item response theory model for identifying subgroups in the population and for highlighting the use of group specific item response parameters and 2 To identify typologies of adolescents based on their propensity for engaging in sexually and substance use risky behaviors. Results indicate that 4 classes of youth exist in the population, with differences in risky sexual behaviors and substance use. The first group had a greater propensity to engage in risky sexual behavior, while group 2 was more likely to smoke tobacco and drink alcohol. Group 3 was the most likely to use other substances, such as marijuana, methamphetamine, and other mind altering drugs, and group 4 had the lowest propensity for engaging in any of the sexual or substance use behaviors included in the survey. Finally, individual items were identified for each group that can be most effective at identifying individuals at greatest risk. Further proposed directions of research and the contribution of this analysis to the existing literature are discussed.

    Alcohol consumption can lead to risky driving and increase the frequency of traffic accidents, injuries and mortalities. The main purpose of our study was to compare simulated driving performance between two groups of drivers, one consumed alcohol and the other not consumed, using a systematic review. In this systematic review, electronic resources and databases including Medline via Ovid SP, EMBASE via Ovid SP, PsycINFO via Ovid SP, PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINHAL) via EBSCOhost were comprehensively and systematically searched. The randomized controlled clinical trials that compared simulated driving performance between two groups of drivers, one consumed alcohol and the other not consumed, were included. Lane position standard deviation (LPSD), mean of lane position deviation (MLPD), speed, mean of speed deviation (MSD), standard deviation of speed deviation (SDSD), number of accidents (NA) and line crossing (LC) were considered as the main parameters evaluating outcomes. After title and abstract screening, the articles were enrolled for data extraction and they were evaluated for risk of biases. Thirteen papers were included in our qualitative synthesis. All included papers were classified as high risk of biases. Alcohol consumption mostly deteriorated the following performance outcomes in descending order: SDSD, LPSD, speed, MLPD, LC and NA. Our systematic review had troublesome heterogeneity. Alcohol consumption may decrease simulated driving performance in alcohol consumed people compared with non-alcohol consumed people via changes in SDSD, LPSD, speed, MLPD, LC and NA. More well-designed randomized controlled clinical trials are recommended. Copyright © 2017. Production and hosting by Elsevier B.V.

    The purpose of traffic law enforcement is to deter risky driving behaviours. The aim of this study was to examine the individual factors of demographic, personality constructs, and attitudes for their association with perceived legitimacy of traffic law enforcement of sleep-related crashes. In total, 293 drivers completed a survey that assessed perceived legitimacy of enforcement and attitudes towards sleepy driving, as well as individual factors of demographic, personality and risk taking factors. The results demonstrate that younger drivers, drivers with higher levels of extraversion, and those with tolerant attitudes towards sleepy driving were less likely to agree that it is legitimate to charge someone if they crash due to sleepiness. The attitudes towards sleepy driving variable had the largest association with perceived legitimacy. Thus, the factors associated with perceived legitimacy of traffic law enforcement of sleep-related crashes are multifaceted. Overall, the findings have relevance with attitudinal and behaviour change programs, particularly with younger drivers. Copyright © 2017 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

    The link between HIV stigma with substance use is understudied. We characterized individuals with high HIV stigma and examined whether HIV stigma contributes to substance use among HIV-positive Russians reporting risky alcohol use. We analyzed data from HERMITAGE, a randomized controlled trial of 700 people living with HIV/AIDS (PLWHA) with past 6-month risky sex and risky alcohol use in St. Petersburg, Russia (2007-2011). Participants who were female and reported depressive symptoms and lower social support were more likely to endorse high HIV stigma (all p's stigma was not significantly associated with the primary outcome unhealthy substance use and was not consistently associated with secondary substance use outcomes. Interventions to enhance social and mental health support for PLWHA, particularly women, may reduce stigma, though such reductions may not correspond to substantial decreases in substance use among this population.

    2005-01-01

    To create a culture of safe practices, we need to understand how and under what conditions the public makes risky decisions about their health. Because risky sexual behaviors are known to be common in young adults, we investigated their decision making regarding sexual activities that could incur a high risk of HIV infection. Sixty young urban adults maintained journals for two weeks and were interviewed regarding condom use and sexual history. We characterized four patterns...

  16. Interactions between risky decisions, impulsiveness and smoking in young tattooed women

    2013-01-01

    Background According to previous studies, one of the common problems of everyday life of persons with tattoos is risky behavior. However, direct examination of the decision making process, as well as factors which determine women’s risk-taking decisions to get tattoos, have not been conducted. This study investigates whether risk taking decision-making is associated with the self-assessment impulsiveness in tattooed women. Methods Young women (aged 18–35 years) with (N = 60) and without (N = 60) tattoos, performed the Iowa Gambling Task (IGT), as a measure of decision-making processes, as well as completing the Barratt Impulsivity Scale (BIS-11). Results Tattooed women showed significantly higher scores in the BIS-11 and preference for disadvantageous decks on the IGT compared to non-tattooed women. There was no significant correlation between risky decision-making in the IGT and BIS-11 impulsivity measures. A significantly higher rate of smoking was observed in the tattooed women. However, the analysis did not reveal a group effect after adjustment for smoking in the IGT and the BIS-11 measures. Conclusions The present study was specifically designed to resolve questions regarding associations between impulsiveness and risky decision-making in tattooed women. It shows that in tattooed women, risky decisions are not a direct result of their self-reported impulsiveness. Smoking does not explain the psychometric differences between tattooed women and controls. PMID:24180254

    Highlights: → Fuel consumption and emissions of Euro 3 scooters defined on different driving cycles. → Comparison of standard, real world driving cycles and measured urban speed patterns. → Statistical analysis of kinematic parameters to group driving cycle in clusters. → Clusters can explain pollutant and fuel consumption behaviour in hot conditions. → Cold start mixture enrichment strategy has a major influence on extra-emissions. - Abstract: Regulated pollutant emissions and fuel consumption were characterized at the exhaust of two Euro 3 4-stroke medium-size motorcycles during the execution of both standard and real world driving cycles. A principal component analysis was carried out to group in a cluster the driving cycles with similar kinematic parameters. Hot start results, analysed according to this cluster grouping, show that the main differences are explained by overall mean speed and high positive acceleration of driving cycles. Lower mean speeds produce higher CO 2 emission factors, while the influence on CO and HC is more complex. NO X are not significantly affected by the driving pattern. Inside the same cluster, the whole duration of the acceleration phases could discriminate emission behaviour. In-depth analysis of cold start results was conducted in order to assess the influence of the driving cycle and vehicle characteristics on cold start duration. Cold start extra emissions are more influenced by the duration of the enrichment phase than by the catalyst light-off. The larger number of accelerations occurring during real world driving cycles produces higher variability of air fuel ratio and hence higher cold start extra emissions.

    Research in cognitive neuropsychology suggests that investigation of the within-person variability, or inconsistency, of cognitive performance may provide valuable insights into ageing mental processes. It is rare though, for this interest in intraindividual variability to extend to everyday activities. As this may provide important information about driving behaviour, we therefore assessed age differences in driving inconsistency in younger (n=24, M age=21.29 years) and older (n=21, M age=71.24 years) persons who drove in residential, urban and motorway conditions in a fully immersive driving simulator. In measures of headway (maintaining a safe distance to a preceding vehicle) and lateral lane position, older drivers exhibited significantly greater performance inconsistency, and this was particularly marked in the faster motorway condition. Older drivers also recorded greater perceived mental demands associated with driving, and greater within-person variability across a range of cognitive measures. The findings suggest that age-related deficits in attentional and executive control may affect the consistency of driving performance in older persons. Discussion considers interventions to introduce in-vehicle systems to help maintain attention in older drivers, and to intervene when safety-critical boundaries are exceeded.

    Customers’ engagement behaviours are considered an important source of value to the company. So far, the discussion has mainly been conceptual and focused on the company’s perspective. By adopting the customer’s perspective we investigated how customers perceive their service relationship...... encounters with a company, using in-depth interviews. We found the following key factors driving and explaining customers’ engagement behaviours: (1) transactions matter and inconsistent engagement behaviours are a reality, (2) mundane products and services are still highly relevant for customers, and (3......) different degrees of customer experience alignment with services and products exist. Moreover, the distinction between true and false engagement behaviours we suggest indeed is relevant and we could establish their mediating capabilities....

    Full Text Available Aim: In the last decade, the prevalence of injecting drugs has been increasing rapidly. Injecting drug use puts one at the risk of risky behaviors that affect the health of individual and society. The present study aims at evaluating and comparing risky behaviors of injecting and non-injecting drug users. Methods: In this cross-sectional descriptive study, 4400 addicts referred to public, private and drop-in-centers (DICs in 2014 were enrolled. The addicts were divided into injecting and non-injecting drug users. A researcher-made questionnaire was used to collect demographic data and the pattern of drug use and risky behavior. Data were analyzed by SPSSV21, chi-square test and ANOVA. A significance level of less than 0.05 was considered. Results: Among the addicts, 4% were injecting drug users (IDUs and 96% non-injecting drug addicts (non-IDUs. The age of the first injection was 24.68 ± 6.45 years old. The age of onset of drug use in IDUs was significantly lower than in non-IDUs (P<0.001. Risky behaviors including the use of shared needles, risky sexual relations, a history of sexually transmitted infections and a history of imprisonment and suicide were significantly higher in IDUs. Addiction relapse and slip during treatment were higher in IDUs (P<0.001. Conclusion: Injecting drug addiction significantly increases the risk of relapse and risky behaviors. Priority should be given to risky behavior prevention programs.

    To investigate the current status on knowledge for unintentional injury and risky behavior among school-age children in Changsha, China, and to provide scientific evidence for the preventive strategies.
 A cross-sectional study was conducted on 866 students who were between 6 and 12 years old in Changsha. Two primary schools were selected by stratified cluster random sampling from all primary schools of Changsha city to collect the information regarding knowledge for unintentional injury and risky behavior occurring in the 6-month period before the survey.
 The mean score for knowledge of unintentional injury was 11.83±2.38. The levels of knowledge for unintentional injury differed significantly in child's age, parents' education background and child's injury history (Pchild's knowledge level was correlated with child's age, mother's education, child's injury history. The mean score for risky behavior was 17.61±10.35. The levels of risky behavior differed significantly in child's gender, father's age to have the child, parents' marriage status, whom does/do child live with, child's injury history and medical history since the birthday (Pchild's injury history, parents' marriage status, child's gender. There was no significant correlation between knowledge and risky behavior (P>0.05).
 It is a common phenomenon in school-age children who are lack of the knowledge for unintentional injury and risky behavior. This study provides useful information on the risk factors for unintentional injury and risky behavior, which would be significant for prevention program.

    With about one quarter of new human immunodeficiency virus (HIV) infections occuring in young people, there is an on-going debate regarding the role of social capital on youth sexual behaviour. Some studies have suggested that high levels of family and community social capital may act as protective factors that lessen the likelihood of negative consequences; while others have concluded that social capital may be a risk factor for risky sexual behaviour among youth. Using data from the Third National Communications Survey (2012) conducted in South Africa, we examined the relationship between perceptions of social capital and youth sexual behaviour measured by age at first sex and condom use among 3 399 males and females (aged between 16 and 24 years). We assessed community perceptions of social capital with questions that measured trust, social participation, and support. The Cox proportional hazards regression model was used to predict the risk for early sexual debut. Logistic regression was used to predict the odds of condom use. There was no association between perceptions of social capital and youth sexual behaviour. This work reveals that youth sexual behaviour in South Africa may be influenced by socio-economic characteristics, especially at the individual level.

    Boonchuay, Chanwit; Ongsakul, Weerakorn

    2011-01-01

    In this paper, an optimal risky bidding strategy for a generating company (GenCo) by self-organising hierarchical particle swarm optimisation with time-varying acceleration coefficients (SPSO-TVAC) is proposed. A significant risk index based on mean-standard deviation ratio (MSR) is maximised to provide the optimal bid prices and quantities. The Monte Carlo (MC) method is employed to simulate rivals' behaviour in competitive environment. Non-convex operating cost functions of thermal generating units and minimum up/down time constraints are taken into account. The proposed bidding strategy is implemented in a multi-hourly trading in a uniform price spot market and compared to other particle swarm optimisation (PSO). Test results indicate that the proposed SPSO-TVAC approach can provide a higher MSR than the other PSO methods. It is potentially applicable to risk management of profit variation of GenCo in spot market.

  6. Age differences in the effect of framing on risky choice: A meta-analysis

    2015-01-01

    The framing of decision scenarios in terms of potential gains versus losses has been shown to influence choice preferences between sure and risky options. Normative cognitive changes associated with aging have been known to affect decision-making, which has led to a number of studies investigating the influence of aging on the effect of framing. Mata, Josef, Samanez-Larkin, and Hertwig (2011) systematically reviewed the available literature using a meta-analytic approach, but did not include tests of homogeneity nor subsequent moderator variable analyses. The current review serves to extend the previous analysis to include such tests as well as update the pool of studies available for analysis. Results for both positively and negatively framed conditions were reviewed using two meta-analyses encompassing data collected from 3,232 subjects across 18 studies. Deviating from the previous results, the current analysis finds a tendency for younger adults to choose the risky option more often than older adults for positively framed items. Moderator variable analyses find this effect to likely be driven by the specific decision scenario, showing a significant effect with younger adults choosing the risky option more often in small-amount financial and large-amount mortality-based scenarios. For negatively framed items, the current review found no overall age difference in risky decision making, confirming the results from the prior meta-analysis. Moderator variable analyses conducted to address heterogeneity found younger adults to be more likely than older adults to choose the risky option for negatively framed high-amount mortality-based decision scenarios. Practical implications for older adults are discussed. PMID:26098168

  7. Developing a driving Safety Index using a Delphi stated preference experiment.

    Whilst empirical evidence is available concerning the effect of some aspects of driving behaviour on safety (e.g. speed choice), there is scant knowledge about safety thresholds, i.e. the point at which behaviour can be considered unsafe. Furthermore, it is almost impossible to ascertain the interaction between various aspects of driving behaviour. For example, how might drivers' lateral control of a vehicle be mediated by their speed choice-are the effects additive or do they cancel each other out. Complex experimental or observational studies would need to be undertaken to establish the nature of such effects. As an alternative, a Delphi study was undertaken to use expert judgement as a way of deriving a first approximation of these threshold and combinatory effects. Using a stated preference technique, road safety professionals make judgements about drivers' safe or unsafe behaviour. The aim was to understand the relative weightings that are assigned to a number of driver behaviours and thereby to construct a Safety Index. As expected, experts were able to establish thresholds, above (or below) which changes to the behavioural parameters had minimal impact on safety. This provided us with a Safety Index, based on a model that had face validity and a convincing range of values. However, the experts found the task of combining these driver behaviours more difficult, reflecting the elusive nature of safety estimates. Suggestions for future validation of our Safety Index are provided.

    To evaluate the effect of training primary care health professionals in behaviour change counselling on the proportion of patients self reporting change in four risk behaviours (smoking, alcohol use, exercise, and healthy eating). Cluster randomised trial with general practices as the unit of randomisation. General practices in Wales. 53 general practitioners and practice nurses from 27 general practices (one each at all but one practice) recruited 1827 patients who screened positive for at least one risky behaviour. Behaviour change counselling was developed from motivational interviewing to enable clinicians to enhance patients' motivation to change health related behaviour. Clinicians were trained using a blended learning programme called Talking Lifestyles. Proportion of patients who reported making beneficial changes in at least one of the four risky behaviours at three months. 1308 patients from 13 intervention and 1496 from 14 control practices were approached: 76% and 72% respectively agreed to participate, with 831 (84%) and 996 (92%) respectively screening eligible for an intervention. There was no effect on the primary outcome (beneficial change in behaviour) at three months (362 (44%) v 404 (41%), odds ratio 1.12 (95% CI 0.90 to 1.39)) or on biochemical or biometric measures at 12 months. More patients who had consulted with trained clinicians recalled consultation discussion about a health behaviour (724/795 (91%) v 531/966 (55%), odds ratio 12.44 (5.85 to 26.46)) and intended to change (599/831 (72%) v 491/996 (49%), odds ratio 2.88 (2.05 to 4.05)). More intervention practice patients reported making an attempt to change (328 (39%) v 317 (32%), odds ratio 1.40 (1.15 to 1.70)), a sustained behaviour change at three months (288 (35%) v 280 (28%), odds ratio 1.36 (1.11 to 1.65)), and reported slightly greater improvements in healthy eating at three and 12 months, plus improved activity at 12 months.

    2012-01-01

    This study has two main objectives. First, it is examined whether the frequent exposure to music video viewing is associated with driving after the consumption of alcohol. Second, it is examined which theoretical framework, a combination of Cultivation Theory and the Theory of Planned Behavior or the Problem Behavior Theory, is suited best to explain this relationship. Participants were 426 Flemish adolescents who took part in a two-wave panel survey (2006-2008) about media use, risk-taking attitudes, intentions, and behaviors. In line with Cultivation Theory and the Theory of Planned Behavior, the results showed that adolescents' music video viewing is a significant marker of later risky driving behavior and that this relationship is mediated through their attitudes and intentions. No support was found for the hypothesis that music video viewing is part of a cluster of problem behaviors (Problem Behavior Theory). Thus, the results of this study seem to indicate that a combination of Cultivation Theory and the Theory of Planned Behavior provides a more useful framework for explaining the relationship between music video viewing and driving after the consumption of alcohol. The implications for prevention and the study's limitations are discussed.

  12. An investigation of r.f. travelling wave current drive using the model

    1988-01-01

    Previous experimental investigations in the use of travelling r.f. waves to drive steady toroidal currents in a toroidal plasma have shown that I t , the amount of current driven, is strongly dependent on the ratio of the static toroidal magnetic field B z , to the strength of the r.f. magnetic field B ω . This dependence is characterised by an initial increase and subsequent decrease of I t when B t /B ω increases. It is shown that this observed behaviour is entirely consistent with the behaviour predicted by the current drive model. Results from numerical computations using the model show good quantitative agreement with the published experimental results

    Sexual behaviour is the core of sexuality matters in adolescents and youths. Their modest or dynamic behaviour vulnerable them to risky sexual behaviours. In Ethiopia, there is scarcity of multicentered representative data on sexual behaviours in students to have a national picture at higher education. This study therefore conducted to assess sexual behaviours and associated factors at Bahir Dar University, Ethiopia. A cross sectional study was conducted among Bahir Dar University students from December to February 2013. Multistage sampling and self administered questionnaires were employed. Descriptive statistics such as frequency and mean were used to describe the study participants in relation to relevant variables. Multivariate analysis was carried for those variables that had a p-value of ≤ 0.2 in the bivariate analysis to identify the predictor variables. Of the 817 study participants, 297 (36.4%) students had ever had sex. The mean age at first sexual practice was 18.6 years. Unprotected sex, having multiple sex partners, sex with commercial sex workers and sex for the exchange of money was practiced by 184 (62%), 126 (42.7%), 22 (7.4%) and 12 (4%) of sexually active students, respectively. The proportion of attending night clubs and watching porn videos was 130 (15.8%) and 534 (65.4%), respectively. Male respondents had significant positive association with watching porn videos (AOR = 4.8, CI = 3.49 - 6.54) and attending night clubs (AOR = 3.9, CI = 2.3 - 6.7). Watching porn videos, attending night clubs, khat chewing and taking alcohol frequently were significantly associated for ever had sex and having multiple sexual partners. Khat chewing practice (AOR = 8.5, CI =1.31 - 55.5) and attending night clubs (AOR = 4.6, CI = 1.8 - 11.77) had statistical significant association with the purpose of sexual intercourse for the sake of money and for having sex with commercial sex workers, respectively. Significant number of students had different risky sexual

    Because the nature of their work seafarers spend long periods of time away from their families and therefore represent a group at risk for sexually transmitted diseases, including HIV infection. This paper reports the results of a survey to evaluate awareness and knowledge of the risk of HIV infection among seafarers. Risky behaviours for HIV transmission were also assessed. The survey was conducted using anonymous questionnaires on 197 workers of 9 vessels and 26 office employees of an Italian shipping company (FINAVAL S.p.A., Rome). The respondents considered HIV/AIDS as one of the diseases with a high risk of transmission. Most respondents had a good general knowledge of HIV/AIDS and on the ways of its transmission. However, there is still lack of knowledge on the basics of this disease. On the other hand, in spite of knowledge and awareness about the risks of the disease, only 56.35% of the interviewed crewmembers used protection in sexual intercourse with occasional partners. Compared to data available in literature, the percentage of self-protecting people is increasing, but the number of seafarers exposing themselves to risky behaviours is still high. As expected, condoms are used with regular partners with lower frequency compared to occasional intercourse. The results of this survey indicate that adequate prevention campaigns and major attention paid to seafarers health is useful for stimulating responsible conduct for the prevention of infectious diseases, including HIV infection. Nevertheless, it is still necessary to increase information about the risk of sexually transmitted diseases and how to reduce it.

    2013-01-01

    Only very recently has research demonstrated that experimentally induced emotion regulation strategies (cognitive reappraisal and expressive suppression) affect risky choice (e.g., Heilman et al., 2010). However, it is unknown whether this effect also operates via habitual use of emotion regulation strategies in risky choice involving deliberative decision making. We investigated the role of habitual use of emotion regulation strategies in risky choice using the "cold" deliberative version of the Columbia Card Task (CCT; Figner et al., 2009). Fifty-three participants completed the Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) and--one month later--the CCT and the PANAS. Greater habitual cognitive reappraisal use was related to increased risk taking, accompanied by decreased sensitivity to changes in probability and loss amount. Greater habitual expressive suppression use was related to decreased risk taking. The results show that habitual use of reappraisal and suppression strategies predict risk taking when decisions involve predominantly cognitive-deliberative processes.

    Full Text Available Aim – Previous studies of the association between polydrug use and other risk behaviours have generally been limited to specific substances and a small number of behaviours. The aim of this study is to obtain better insight into polydrug use (comprising legal and illegal substances: tobacco, alcohol, tranquillisers/sedatives, cannabis, and other illegal drugs and its association with co-occurring problem behaviours drawn from various broad domains (sexual, aggressive, delinquent, school achievement, relationships among European adolescents. METHODS – Data were obtained from 101,401 16-year-old students from 35 European countries participating in the 2011 ESPAD survey. Associations between polydrug use and other problem behaviours were examined by multinomial and binary logistic regression analyses. RESULTS – Tranquillisers/sedatives appeared among the commonest combinations in the polydrug use pattern, especially for females. A strong trend was found between levels of involvement with polydrug use and other problem behaviours for both genders. The highest associations with polydrug use were for problems with the police, risky sexual behaviour and skipping school. Gender differences showed higher prevalences among boys than girls of problem behaviours of aggressive, antisocial type, while girls prevailed over boys in relationship problems. CONCLUSION – An incremental relationship exists between the level of involvement with polydrug use and the co-occurrence of problem behaviours. Preventative interventions should consider the misuse of tranquillisers/sedatives within the context of polydrug use by adolescents and expand their target groups towards multiple problem behaviours.

    Increased propensity for risky behavior in adolescents, particularly in peer groups, is thought to reflect maturational imbalance between reward processing and cognitive control systems that affect decision-making. We used functional magnetic resonance imaging (fMRI) to investigate brain functional correlates of risk-taking behavior and effects of peer influence in 18-19-year-old male adolescents. The subjects were divided into low and high risk-taking groups using either personality tests or risk-taking rates in a simulated driving task. The fMRI data were analyzed for decision-making (whether to take a risk at intersections) and outcome (pass or crash) phases, and for the influence of peer competition. Personality test-based groups showed no difference in the amount of risk-taking (similarly increased during peer competition) and brain activation. When groups were defined by actual task performance, risk-taking activated two areas in the left medial prefrontal cortex (PFC) significantly more in low than in high risk-takers. In the entire sample, risky decision-specific activation was found in the anterior and dorsal cingulate, superior parietal cortex, basal ganglia (including the nucleus accumbens), midbrain, thalamus, and hypothalamus. Peer competition increased outcome-related activation in the right caudate head and cerebellar vermis in the entire sample. Our results suggest that the activation of the medial (rather than lateral) PFC and striatum is most specific to risk-taking behavior of male adolescents in a simulated driving situation, and reflect a stronger conflict and thus increased cognitive effort to take risks in low risk-takers, and reward anticipation for risky decisions, respectively. The activation of the caudate nucleus, particularly for the positive outcome (pass) during peer competition, further suggests enhanced reward processing of risk-taking under peer influence.
