    Cigarette smoking is a behavior, which is influenced by genetic, demographic, and psychological factors. A large body of research has examined the association of cigarette smoking variables with individual differences in personality traits. The aim of the current study was to replicate the findings of higher self-reported impulsivity in smokers compared with never-smokers in a German sample using Eysenck´s construct of impulsivity. Furthermore, it was intended to further the knowledge about associations between different self-reported impulsivity components and different smoking variables. We used the Impulsiveness-Venturesomeness-Empathy questionnaire (I7) to measure self-reported impulsiveness and venturesomeness and the Temperament and Character Inventory (TCI) to measure novelty seeking (NS) in a sample of 82 nicotine-dependent smokers and 119 never-smokers. Smokers scored higher on impulsiveness, venturesomeness, and NS than never-smokers independent of age, gender, and years of education. We found a significant association between venturesomeness, impulsiveness and smoking status in daily smokers. In summary, this study provides evidence that impulsiveness and venturesomeness as well as the novelty-seeking subscale extravagance are significantly associated with smoking status in a German sample of female and male smokers compared with never-smokers.

    Impulsivity is considered a core feature of problem gambling; however, self-reported impulsivity and inhibitory control may reflect disparate constructs. We examined self-reported impulsivity and inhibitory control in 39 treatment-seeking problem gamblers and 41 matched controls using a range of self-report questionnaires and laboratory inhibitory control tasks. We also investigated differences between treatment-seeking problem gamblers who prefer strategic (e.g., sports betting) and nonstrategic (e.g., electronic gaming machines) gambling activities. Treatment-seeking problem gamblers demonstrated elevated self-reported impulsivity, more go errors on the Stop Signal Task, and a lower gap score on the Random Number Generation task than matched controls. However, overall we did not find strong evidence that treatment-seeking problem gamblers are more impulsive on laboratory inhibitory control measures. Furthermore, strategic and nonstrategic problem gamblers did not differ from their respective controls on either self-reported impulsivity questionnaires or laboratory inhibitory control measures. Contrary to expectations, our results suggest that inhibitory dyscontrol may not be a key component for some treatment-seeking problem gamblers.

    Stress and impulsivity contribute to alcohol use, and stress may also act via impulsivity to increase drinking behavior. Impulsivity represents a multi-faceted construct and self-report and behavioral assessments may effectively capture distinct clinically relevant factors. The present research investigated whether aspects of impulsivity mediate the effect of stress on alcohol use. A community-based sample of 192 men and women was assessed on measures of cumulative stress, alcohol use, self-reported impulsivity, and behavioral choice and response impulsivity. Data were analyzed using regression and bootstrapping techniques to estimate indirect effects of stress on drinking via impulsivity. Cumulative adversity exhibited both direct effects and indirect effects (via self-reported impulsivity) on drinking behavior. Additional models examining specific types of stress indicated direct and indirect effects of trauma and recent life events, and indirect effects of major life events and chronic stressors on drinking behavior. Overall, cumulative stress was associated with increased drinking behavior, and this effect was partially mediated by self-reported impulsivity. Self-reported impulsivity also mediated the effects of different types of stress on drinking behavior. These findings highlight the value of mediation models to examine the pathways through which different types of stress increase drinking behavior. Treatment and prevention strategies should focus on enhancing stress management and self-control.

    Few studies have directly investigated impulsivity in Huntington's disease (HD) despite known changes in dopaminergic and frontal functioning, changes that have been associated with impulsivity in other disorders and in the normal population. This study sought to further categorize impulsivity in HD through examining differences in self-reported impulsivity between community controls and HD patients, the relationship between executive dysfunction and impulsivity, and the relationship of a reward/punishment behavioral inhibition task in relation to these self-report measures. It was expected that HD patients would report higher impulsivity and executive dysfunction and that these measures would relate to a reward/punishment behavioral inhibition task. The Barratt Impulsivity Scale (BIS-11) and Behavioral Inhibition/Behavioral Activation Scale (BIS/BAS) were completed, and the Mini-Mental State Examination (MMSE) and a reward-based flanker task with punishing and rewarding conditions were administered to 22 HD patients and 14 control participants. HD patients reported higher trait impulsivity (BIS-11) and executive dysfunction (Frontal Systems Behavior Scale, FrSBE) but not increased impulsivity on the BIS/BAS relative to controls. Higher BIS-11 scores were related to increased self-reported executive dysfunction and the attention/working memory factor of the MMSE. On a reward/punishment behavioral inhibition task, BAS was uniquely related to increased accuracy on rewarding trials of the flanker task, but was not related to punishing trials in HD patients. The relationships found suggest that trait impulsivity is reported higher in HD and may not be driven by altered reward evaluation and the appetitive nature of stimuli but rather by increased executive dysfunction and lack of sensitivity to punishment. Impulsivity in HD may represent a combination of trait impulsivity, altered dopaminergic circuitry, and executive dysfunction. Understanding impulsivity in HD is

    Background and aims Multiplayer Online Battle Arena (MOBA) games have become the most popular type of video games played worldwide, superseding the playing of Massively Multiplayer Online Role-Playing Games and First-Person Shooter games. However, empirical studies focusing on the use and abuse of MOBA games are still very limited, particularly regarding impulsivity, which is an indicator of addictive states but has not yet been explored in MOBA games. In this context, the objective of the present study is to explore the associations between impulsivity and symptoms of addictive use of MOBA games in a sample of highly involved League of Legends (LoL, currently the most popular MOBA game) gamers. Methods Thirty-six LoL gamers were recruited and completed both experimental (Single Key Impulsivity Paradigm) and self-reported impulsivity assessments (s-UPPS-P Impulsive Behavior Scale, Barratt Impulsiveness Scale), in addition to an assessment of problematic video game use (Problematic Online Gaming Questionnaire). Results Results showed links between impulsivity-related constructs and signs of excessive MOBA game involvement. Findings indicated that impaired ability to postpone rewards in an experimental laboratory task was strongly related to problematic patterns of MOBA game involvement. Although less consistent, several associations were also found between self-reported impulsivity traits and signs of excessive MOBA game involvement. Conclusions Despite these results are preliminary and based upon a small (self-selected) sample, the present study highlights potential psychological factors related to the addictive use of MOBA games.

    This study examines the association of self-reported impulsivity to nonsuicidal self-injury, suicidal ideation, suicide attempts, and completed suicides in a clinical sample of 508 Finnish adolescents (aged 12-17) treated in psychiatric inpatient care between April 2001 and March 2006. The Schedule for Affective Disorder and Schizophrenia for School-Age Children Present and Lifetime interview was used to gather information on psychiatric disorders, impulsivity, and suicidality of the adolescents. Mortality data were obtained from the national cause of death register. In adolescent girls, impulsivity was significantly associated with suicidal ideation and attempts and completed suicides in adolescent boys. Of adolescent boys with impulsivity, 10.4% had died by suicide during the follow-up time. For preventive purposes, health care professionals are encouraged asked adolescents targeted questions about impulsivity and to consider the associated risk of suicidality identified in this study.

  9. Self-reported impulsivity, rather than sociosexuality, predicts women's preferences for masculine features in male faces.

    Boothroyd, Lynda G; Brewer, Gayle

    2014-07-01

    Previous research has suggested that an individual's sociosexual orientation (i.e., their willingness to engage in sexual behavior outside of long-term relationships) may influence the qualities they find attractive in a potential mate. Results, however, have not been consistent and, moreover, studies have tended to draw from specific social groups. Here, we tested the relationship between sociosexuality and female's preferences for masculinity in male faces, using a diverse population. We furthermore investigated impulsivity alongside sociosexuality, as this trait has been suggested as a "root" cause of variation in sexual behavior (Cross, 2010) and thus may better explain variation in mate choice. Results showed a significant association between increases in both sociosexuality and two subcomponents of impulsivity and greater preferences for masculine male features. Regression analysis suggested that a subcomponent of impulsivity, namely lack of planning, was the primary determinant of preferences. We discuss the implications these results have for our understanding of female attraction to masculine features.

    To test the hypothesis that early-onset alcoholics (EOAs) can be differentiated from late-onset alcoholics (LOAs) by more severe substance-related problems and higher levels of impulsivity and aggression. A cross-sectional patient survey with a community comparison group. The European Addiction Severity Index was used to assess substance-related problems and the Barratt Impulsiveness Scale, the Dutch version of the Zuckermann Sensation Seeking Scale and the Buss-Durkee Hostility Inventory were used to assess impulsive and aggressive traits. Impulsive decision making was assessed using a delay discounting task (DDT) with hypothetical monetary rewards. Participants were EOAs (n = 42) and LOAs (n = 46) recruited from an addiction treatment centre and an unmatched, non-substance-abusing comparison group (n = 54). Findings The EOAs had higher levels of impulsive decision making than both the LOAs and the comparison group. The EOAs had higher scores than the LOAs on measures of impulsiveness, aggressiveness and the severity of substance-related problems. This study provides evidence that EOAs are more impulsive and aggressive than LOAs. Further identification of alcoholism subtypes based on dimensions of impulsivity should be considered in the light of their relationship with pharmacological and behavioural treatment interventions.

  12. Self-reported impulsivity, but not behavioral approach or inhibition, mediates the relationship between stress and self-control.

    Stress has been associated with poor self-control. Individual differences in impulsivity and other behavioral tendencies may influence the relationship of stress with self-control, although this possibility has not been examined to date. The present research investigated whether cumulative stress is associated with poor self-control, and whether this relationship is mediated by impulsivity, behavioral approach, and behavioral inhibition in men and women. A community sample of 566 adults (319 women and 247 men) was assessed on the Cumulative Adversity Interview, Brief Self-control Scale, Barratt Impulsivity Scale, and Behavioral Activation System and Behavioral Inhibition System Scale (BIS/BAS). Data were analyzed using regression and bootstrapping techniques. In the total sample, the effects of cumulative stress on self-control were mediated by impulsivity. Neither behavioral inhibition nor behavioral approach mediated the association between cumulative stress and self-control in the total sample. Results were similar when men and women were considered separately, with impulsivity, but not behavioral inhibition or approach, mediating the association between cumulative stress and self-control. Impulsive individuals might benefit preferentially from interventions focusing on stress management and strategies for improving self-control. Copyright © 2014 Elsevier Ltd. All rights reserved.

  13. The role of self-reported impulsivity and reward sensitivity versus neurocognitive measures of disinhibition and decision-making in the prediction of relapse in pathological gamblers.

    2008-01-01

    Disinhibition and decision-making skills play an important role in theories on the cause and outcome of addictive behaviors such as substance use disorders and pathological gambling. In recent studies, both disinhibition and disadvantageous decision-making strategies, as measured by neurocognitive tests, have been found to influence the course of substance use disorders. Research on factors affecting relapse in pathological gambling is scarce. This study investigated the effect of both self-reported impulsivity and reward sensitivity, and neurocognitively assessed disinhibition and decision-making under conflicting contingencies, on relapse in a group of 46 pathological gamblers. Logistic regression analysis indicated that longer duration of the disorder and neurocognitive indicators of disinhibition (Stop Signal Reaction Time) and decision-making (Card Playing Task) were significant predictors of relapse (explaining 53% of the variance in relapse), whereas self-reported impulsivity and reward sensitivity did not significantly predict relapse. Overall classification accuracy was 76%, with a positive classification accuracy of 76% and a negative classification accuracy of 75%. Duration of the disorder and neurocognitive measures of disinhibition and decision-making are powerful predictors of relapse in pathological gambling. The results suggest that endophenotypical neurocognitive characteristics are more promising in the prediction of relapse in pathological gambling than phenotypical personality characteristics. Neurocognitive predictors may be useful to guide treatment planning of follow-up contacts and booster sessions.

  18. "Impulsive" youth suicide attempters are not necessarily all that impulsive.

    Witte, Tracy K; Merrill, Katherine A; Stellrecht, Nadia E; Bernert, Rebecca A; Hollar, Daniel L; Schatschneider, Christopher; Joiner, Thomas E

    2008-04-01

    The relationship between impulsivity and suicide has been conceptualized in the literature as a direct one. In contrast, Joiner's [Joiner, T.E., 2005. Why people die by suicide. Harvard University Press, Cambridge, MA.] theory posits that this relationship is indirect in that impulsive individuals are more likely to engage in suicidal behavior because impulsivity makes one more likely to be exposed to painful and provocative stimuli. Adolescents were selected from the Youth Risk Behavior Survey (YRBS) sample between the years of 1993-2003 who had planned for a suicide attempt but did not actually attempt (n=5685), who did not plan but did attempt ("impulsive attempters;" n=1172), and who both planned and attempted (n=4807). Items were selected from the YRBS to assess demographic variables, suicidal behaviors, and impulsive behaviors. Participants who had planned suicide without attempting were significantly less impulsive than those who had attempted without planning and than those who had both planned and attempted. Crucially, participants who had made a suicide attempt without prior planning were less impulsive than those who had planned and attempted. We were unable to conduct a multi-method assessment (i.e., measures were self-report); the measure of impulsivity consisted of items pulled from the YRBS rather than a previously validated impulsivity measure. The notion that the most impulsive individuals are more likely to plan for suicide attempts is an important one for many reasons both theoretical and clinical, including that it may refine risk assessment and attendant clinical decision-making.

  19. Impulsivity in borderline personality disorder: a matter of disturbed impulse control or a facet of emotional dysregulation?

    Sebastian, Alexandra; Jacob, Gitta; Lieb, Klaus; Tüscher, Oliver

    2013-02-01

    Impulsivity is regarded as a clinical, diagnostic and pathophysiological hallmark of borderline personality disorder (BPD). Self-report measures of impulsivity consistently support the notion of higher impulsive traits in BPD patients as compared to healthy control subjects. Laboratory tests of impulsivity, i.e. neuropsychological tests of impulse control render weak and inconsistent results both across different cognitive components of impulse control and within the same cognitive component of impulse control. One important factor worsening impulsive behaviors and impulse control deficits in BPD is comorbid attention-deficit/hyperactivity disorder (ADHD). In addition, emotional dysregulation interacts with impulse control especially for BPD salient emotions. In sum, although basic mechanisms of impulse control seem not to be disturbed in BPD, clinically well observed impulsive behaviors may be explained by comorbid ADHD or may be the consequence of dysregulation of BPD salient emotions.

  20. The clinical assessment of impulsivity

    Nagesh Brahmavar Pai

    2018-01-01

    Full Text Available The term impulsivity is often used to describe behavior that is both spontaneous and detrimental. Impulsivity is multidimensional and derives from personality, general psychopathology as well as specific mental disorders. Thus, the construct of impulsivity is important as it is associated with numerous mental disorders as well as socially deviant behaviors ranging from behaviors targeted towards others such as aggression, to behaviors targeted toward oneself, for example, self-harm and suicide. As a clinical construct impulsivity is highly predictive of poor prognosis thus further emphasizing its clinical relevance. Therefore, the need exists for impulsivity to be clinically assessed and this assessment should take place at the same time as the assessment of risk. As risk and impulsivity are interrelated and interact. Although there are existing self-report rating scales for trait-based impulsivity, a dearth exists in regards to assessment of impulsivity in clinical practice that is focused and pragmatic. Thus, a pragmatic rubric to guide the individualized assessment of impulsivity in a clinical population is proposed. The quadrants espoused will assist both with the formulation of questions and categorization of responses to determine the most appropriate interventions for the client.

  2. Multiple modes of impulsivity in Parkinson's disease.

    Cristina Nombela

    Full Text Available Cognitive problems are a major factor determining quality of life of patients with Parkinson's disease. These include deficits in inhibitory control, ranging from subclinical alterations in decision-making to severe impulse control disorders. Based on preclinical studies, we proposed that Parkinson's disease does not cause a unified disorder of inhibitory control, but rather a set of impulsivity factors with distinct psychological profiles, anatomy and pharmacology. We assessed a broad set of measures of the cognitive, behavioural and temperamental/trait aspects of impulsivity. Sixty adults, including 30 idiopathic Parkinson's disease patients (Hoehn and Yahr stage I-III and 30 healthy controls, completed a neuropsychological battery, objective behavioural measures and self-report questionnaires. Univariate analyses of variance confirmed group differences in nine out of eleven metrics. We then used factor analysis (principal components method to identify the structure of impulsivity in Parkinson's disease. Four principal factors were identified, consistent with four different mechanisms of impulsivity, explaining 60% of variance. The factors were related to (1 tests of response conflict, interference and self assessment of impulsive behaviours on the Barrett Impulsivity Scale, (2 tests of motor inhibitory control, and the self-report behavioural approach system, (3 time estimation and delay aversion, and (4 reflection in hypothetical scenarios including temporal discounting. The different test profiles of these four factors were consistent with human and comparative studies of the pharmacology and functional anatomy of impulsivity. Relationships between each factor and clinical and demographic features were examined by regression against factor loadings. Levodopa dose equivalent was associated only with factors (2 and (3. The results confirm that impulsivity is common in Parkinson's disease, even in the absence of impulse control disorders, and

  3. The relationship between impulsive choice and impulsive action: a cross-species translational study.

    Nienke Broos

    Full Text Available Maladaptive impulsivity is a core symptom in various psychiatric disorders. However, there is only limited evidence available on whether different measures of impulsivity represent largely unrelated aspects or a unitary construct. In a cross-species translational study, thirty rats were trained in impulsive choice (delayed reward task and impulsive action (five-choice serial reaction time task paradigms. The correlation between those measures was assessed during baseline performance and after pharmacological manipulations with the psychostimulant amphetamine and the norepinephrine reuptake inhibitor atomoxetine. In parallel, to validate the animal data, 101 human subjects performed analogous measures of impulsive choice (delay discounting task, DDT and impulsive action (immediate and delayed memory task, IMT/DMT. Moreover, all subjects completed the Stop Signal Task (SST, as an additional measure of impulsive action and filled out the Barratt impulsiveness scale (BIS-11. Correlations between DDT and IMT/DMT were determined and a principal component analysis was performed on all human measures of impulsivity. In both rats and humans measures of impulsive choice and impulsive action did not correlate. In rats the within-subject pharmacological effects of amphetamine and atomoxetine did not correlate between tasks, suggesting distinct underlying neural correlates. Furthermore, in humans, principal component analysis identified three independent factors: (1 self-reported impulsivity (BIS-11; (2 impulsive action (IMT/DMT and SST; (3 impulsive choice (DDT. This is the first study directly comparing aspects of impulsivity using a cross-species translational approach. The present data reveal the non-unitary nature of impulsivity on a behavioral and pharmacological level. Collectively, this warrants a stronger focus on the relative contribution of distinct forms of impulsivity in psychopathology.

  4. The Effect of Implicit Preferences on Food Consumption: Moderating Role of Ego Depletion and Impulsivity

    2016-01-01

    Ego depletion has been found to moderate the effect of implicit preferences on food consumption, such that implicit preferences predict consumption only under a depleted state. The present study tested how trait impulsivity impacts the effect of implicit preferences on food consumption in a depleted condition. Trait impulsivity was measured by means of self-report and a stop signal task. Results showed that both self-reported impulsivity and behavioral impulsivity moderated the ‘depletion and then eating according to implicit preferences’ effect, albeit in different ways. Participants high in self-reported impulsivity and low in behavioral impulsivity were more vulnerable to the effect of depletion on eating. The implications of these results for extant theories are discussed. Future research is needed to verify whether or not trait impulsivity is associated with vulnerability to depletion across different self-control domains. PMID:27881966

  5. Impulsivity and Cluster B Personality Disorders.

    Turner, Daniel; Sebastian, Alexandra; Tüscher, Oliver

    2017-03-01

    Impulsivity is a multifaceted construct and an important personality trait in various mental health conditions. Among personality disorders (PDs), especially cluster B PDs are affected. The aims of this review are to summarize the relevant findings of the past 3 years concerning impulsivity in cluster B PDs and to identify those subcomponents of self-reported impulsivity and experimentally measured impulse control that are most affected in these disorders. All studies referred to antisocial (ASPD) or borderline PD (BPD), and none were found for narcissistic or histrionic PD. In ASPD as well as BPD, self-report scales primarily revealed heightened impulsivity compared to healthy controls. In experimental tasks, ASPD patients showed impairments in response inhibition, while fewer deficits were found in delay discounting. BPD patients showed specific impairments in delay discounting and proactive interference, while response inhibition was less affected. However, after inducing high levels of stress, deficits in response inhibition could also be observed in BPD patients. Furthermore, negative affect led to altered brain activation patterns in BPD patients during impulse control tasks, but no behavioral impairments were found. As proposed by the DSM-5 alternative model for personality disorders, heightened impulsivity is a core personality trait in BPD and ASPD, which is in line with current research findings. However, different components of experimentally measured impulse control are affected in BPD and ASPD, and impulsivity occurring in negative emotional states or increased distress seems to be specific for BPD. Future research could be focused on measures that assess impulsive behaviors on a momentary basis as this is a promising approach especially for further ecological validation and transfer into clinical practice.

    Suicidal behavior has been recognized as an increasing problem among alcohol-dependent subjects. The aim of the study was to identify correlates of impulsive and non-impulsive suicide attempts among a treated population of alcohol-dependent patients. A total of 154 patients with alcohol dependence consecutively admitted for addiction treatment participated in the study. Suicidal behavior was assessed together with severity of alcohol dependence, childhood abuse, impulsivity, and family history. A stop-signal procedure was used as a behavioral measure of impulsivity. Lifetime suicide attempts were reported by 43% of patients in alcohol treatment; of which 62% were impulsive. Compared to patients without a suicide attempt, those with a non-impulsive attempt were more likely to have a history of sexual abuse (OR=7.17), a family history of suicide (OR=4.09), and higher scores on a personality measure of impulsiveness (OR=2.27). The only significant factor that distinguished patients with impulsive suicide attempts from patients without a suicide attempt and from patients with a non-impulsive suicide attempt was a higher level of behavioral impulsivity (OR=1.84-2.42). Retrospective self-report of suicide attempts and family history. Lack of diagnostic measure.

  7. "Impulsive" suicide attempts: What do we really mean?

    May, Alexis M; Klonsky, E David

    2016-07-01

    Suicide attempts are often regarded as impulsive acts. However, there is little consensus regarding the definition or clinical characteristics of an "impulsive" attempt. To clarify this issue, we examined 3 indicators of the impulsivity of an attempt: (a) preparation, (b) time contemplating the attempt, and (c) self-report that impulsivity motivated the attempt. We examined relationships among the indicators and their relationship to trait impulsivity and characteristics of the suicide attempt. Adult participants (N = 205) with a history of suicide attempts were administered validated interviews and questionnaires. In general, the 3 attempt impulsivity indicators correlated only moderately with each other and not at all with trait impulsivity or with important characteristics of the attempt (e.g., lethality, preattempt communication, motivations). However, there were 2 exceptions. First, intent to die was inversely related to the 3 attempt impulsivity indicators (rs ranged from -.17 to .45) such that more impulsive attempts were associated with lower intent. Second, self-report that the attempt was motivated by impulsivity was related to 3 facets of trait impulsivity (rs ranged from .16 to .41). These findings suggest that individuals endorsing trait impulsivity are likely to describe their attempts as motivated by impulsivity, regardless of the presence of preparation or prolonged contemplation. Overall, study results suggest that the common conception of a unidimensional impulsive attempt may be inaccurate and that the emphasis on general impulsivity in prevention guidelines should be tempered. Implications for suicide risk assessment and prevention are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Patients with borderline personality disorder (BPD) frequently exhibit impulsive behavior, and self-reported impulsivity is typically higher in BPD patients when compared to healthy controls. Previous functional neuroimaging studies have suggested a link between impulsivity, the ventral striatal response to reward anticipation, and prediction errors. Here we investigated the striatal neural response to monetary gain and loss anticipation and their relationship with impulsivity in 21 female BP...

  11. Impulsive social influence increases impulsive choices on a temporal discounting task in young adults.

    Jodi M Gilman

    Full Text Available Adolescents and young adults who affiliate with friends who engage in impulsive behavior are more likely to engage in impulsive behaviors themselves, and those who associate with prosocial (i.e. more prudent, future oriented peers are more likely to engage in prosocial behavior. However, it is difficult to disentangle the contribution of peer influence vs. peer selection (i.e., whether individuals choose friends with similar traits when interpreting social behaviors. In this study, we combined a novel social manipulation with a well-validated delay discounting task assessing impulsive behavior to create a social influence delay discounting task, in which participants were exposed to both impulsive (smaller, sooner or SS payment and non-impulsive (larger, later or LL payment choices from their peers. Young adults in this sample, n = 51, aged 18-25 had a higher rate of SS choices after exposure to impulsive peer influence than after exposure to non-impulsive peer influence. Interestingly, in highly susceptible individuals, the rate of non-impulsive choices did not increase after exposure to non-impulsive influence. There was a positive correlation between self-reported suggestibility and degree of peer influence on SS choices. These results suggest that, in young adults, SS choices appear to be influenced by the choices of same-aged peers, especially for individuals who are highly susceptible to influence.

  13. Comparison among various methods of assessment of impulsiveness.

    Carrillo-de-la-Peña, M T; Otero, J M; Romero, E

    1993-10-01

    The current confused status of the research on impulsivity may be attributed to the lack of precise definitions, the reliance of most operationalizations on a single index, and inconsistency among different measures of the construct. Empirical measurements of impulsivity by self-reports, rating scales, or performance tasks suggest that the instruments employed measure aspects that have very little in common, a finding that throws serious doubts on the validity of the construct and implies a need for further research. To clarify this topic, we applied four different measures of impulsivity to 46 7th-grade (12 to 13 years old) schoolchildren. The children were rated by their teachers on an impulsivity behavior scale and were administered Kagan's Matching Familiar Figures Test, Version MFF-20, and two self-report forms, the Eysenck Impulsiveness Questionnaire, and the Barratt Impulsiveness Scale. Although the results confirmed the lack of convergence among these measures, high latencies on matching were associated with the cognitive aspect of the self-report scales. Treating impulsivity as a multidimensional construct is discussed.

    2018-04-01

    Studies have reliably identified an association between suicide attempts and executive functions such as decision making (DM) and inhibitory control (IC) in patients with mood disorders. As such, the present study aimed to investigate the association between inhibition, DM, impulsivity and the history of suicide attempts in individuals with bipolar (BD) or major depressive disorder (MDD), identifying which assessment instruments may be most strongly associated with suicide in clinical samples. The sample included 80 control subjects and two groups of patients with BD and MDD, matched by age and education (26 with a history of suicide attempts [MD+], and 26 with no such history [MD-]). Participants completed behavioral and self-report measures of DM and IC, which were compared between groups using ANCOVA, followed by logistic regression for patients with mood disorders only, and the presence or absence of a history of suicide as the outcome. Cognitive performance did not differ between groups. The MD+ group showed significantly higher motor and attentional impulsivity on the BIS-11 than the MD- and control groups. A regression analysis containing these scores showed that motor impulsivity was the only significant predictor of a history of suicide (OR = 1.14; 95%CI 1.00-1.30). Self-reported motor impulsivity was a significant predictor of suicide. These findings underscore the importance of self-report measures in neuropsychological assessment, and their contributions to the management and prognosis of patients with mood disorders. Lastly, they point to the role of impulsivity as a target for interventions and public policy on suicide prevention. Copyright © 2018 Elsevier Inc. All rights reserved.

  16. Impulsive behavior in adults with attention deficit/ hyperactivity disorder: characterization of attentional, motor and cognitive impulsiveness.

    Malloy-Diniz, L; Fuentes, D; Leite, W Borges; Correa, H; Bechara, A

    2007-07-01

    Attention-deficit/hyperactivity disorder (ADHD) is characterized by inattention and/or hyperactivity/impulsivity. Impulsivity persists in adults with ADHD and might be the basis of much of the impairment observed in the daily lives of such individuals. The objective of this study was to address the presence, and more importantly, the three dimensions of impulsivity: attentional, non-planning and motor, in how they may relate to neuropsychological mechanisms of impulse control. We studied a sample of 50 adults with ADHD and 51 healthy comparison controls using the Barratt Impulsivity Scale Version 11 (BIS), and neuropsychological tasks, namely the Continuous Performance Task (CPT-II) and the Iowa Gambling Task (IGT). The ADHD group showed more signs of impulsivity on the three dimensions of BIS, committed more errors of omission and commission on the CPT-II, and made more disadvantageous choices on the IGT. These results support the existence of deficits related to three components of impulsivity: motor, cognitive, and attentional among adults with ADHD. Most importantly, this study also highlights the complementary nature of self-report questionnaires and neuropsychological tasks in the assessment of impulsivity in ADHD adults.

  17. Domain-Specific Relationships in Sexual Measures of Impulsive Behavior.

    Mahoney, Colin T; Lawyer, Steven R

    2018-04-25

    Impulsivity is an important construct for understanding sexual behaviors, but behavioral and self-report measures of impulsivity often are not correlated. One possible explanation for this is that there is little shared variance in the measures because behavioral measures index impulsivity by asking questions about monetary preferences, while self-report measures index impulsivity by asking about a broad range of real-world outcomes (including those of a sexual nature) largely unrelated to money-related preferences. Undergraduate students (total N = 105; female n = 77, male n = 28) completed laboratory measures-delay discounting (DD) and probability discounting (PD)-for two different outcomes-money and sexual activity. Participants also completed the Delaying Gratification Inventory (DGI), which measures difficulty with delaying gratification (i.e., impulsivity) across different domains, including money and physical pleasures. Findings indicated that DD and PD for money were not related to any of the DGI subscales. However, DD for sexual activity was significantly related to the DGI Physical Pleasures subscale, but not other subscales. These findings suggest that the relationship between behavioral and self-report measures of impulsive choice may be stronger when both are measuring domain-specific rather than domain-general behavioral patterns, but further research is warranted.

  18. Temperament and impulsivity predictors of smoking cessation outcomes.

    Francisca López-Torrecillas

    Full Text Available AIMS: Temperament and impulsivity are powerful predictors of addiction treatment outcomes. However, a comprehensive assessment of these features has not been examined in relation to smoking cessation outcomes. METHODS: Naturalistic prospective study. Treatment-seeking smokers (n = 140 were recruited as they engaged in an occupational health clinic providing smoking cessation treatment between 2009 and 2013. Participants were assessed at baseline with measures of temperament (Temperament and Character Inventory, trait impulsivity (Barratt Impulsivity Scale, and cognitive impulsivity (Go/No Go, Delay Discounting and Iowa Gambling Task. The outcome measure was treatment status, coded as "dropout" versus "relapse" versus "abstinence" at 3, 6, and 12 months endpoints. Participants were telephonically contacted and reminded of follow-up face to face assessments at each endpoint. The participants that failed to answer the phone calls or self-reported discontinuation of treatment and failed to attend the upcoming follow-up session were coded as dropouts. The participants that self-reported continuing treatment, and successfully attended the upcoming follow-up session were coded as either "relapse" or "abstinence", based on the results of smoking behavior self-reports cross-validated with co-oximetry hemoglobin levels. Multinomial regression models were conducted to test whether temperament and impulsivity measures predicted dropout and relapse relative to abstinence outcomes. RESULTS: Higher scores on temperament dimensions of novelty seeking and reward dependence predicted poorer retention across endpoints, whereas only higher scores on persistence predicted greater relapse. Higher scores on the trait dimension of non-planning impulsivity but not performance on cognitive impulsivity predicted poorer retention. Higher non-planning impulsivity and poorer performance in the Iowa Gambling Task predicted greater relapse at 3 and 6 months and 6 months

  19. Impulsive responses to emotion as a transdiagnostic vulnerability to internalizing and externalizing symptoms.

    Johnson, Sheri L; Carver, Charles S; Joormann, Jutta

    2013-09-25

    This study explored the hypothesis that impulsive reactions to heightened emotion may reflect a transdiagnostic vulnerability to both externalizing and internalizing symptoms. A sample of undergraduates completed self-report measures of aggression, borderline personality disorder symptoms, anxiety symptoms, and alcohol problems, and a subset completed interviews that assessed suicidality. All participants also completed self-report measures relating to impulsivity. We predicted that emotion-reactive impulsivity, but not other aspects of impulsivity, would be related to the set of psychopathology symptoms. Multiple regression analyses found that emotion-reactive impulsivity was uniquely related to each of the psychopathology scales, whereas non-emotion-relevant impulsivity was uniquely related only to alcohol problems. Discussion focuses on limitations and clinical implications. © 2013 Elsevier B.V. All rights reserved.

Skin morbidities in Denmark are common, and the distribution of prevalence estimates in the Danish population parallel those of the Norwegian population, although...

  1. Sex differences in dimensions of impulsivity in a non-clinical sample.

    Lage, Guilherme Menezes; Albuquerque, Maicon Rodrigues; Fuentes, Daniel; Corrêa, Humberto; Malloy-Diniz, Leandro Fernandes

    2013-10-01

    Impulsivity has been more closely associated with men than with women because men are more often involved in illegal behaviors. The few studies that have investigated sex differences in impulsivity have used self-report questionnaires and have obtained contradictory results. Two computerized behavioral tests were administered to 125 healthy undergraduate students (75 women, M age 23.8 yr.; 50 men, M age 25.0 yr.). Men exhibited higher scores on motor impulsivity, but there were no significant differences between men and women on attentional and non-planning impulsivity scores. These findings are discussed in terms of the relationship between impulsivity and low- and high-order control.

    Overeating and obesity are associated with impulsivity. In studies among patients with a substance use disorder, impulsivity was found to be associated with substance-related attentional bias. This study examined whether obesity, impulsivity and food craving are associated with an attentional bias for high-calorie food. Obese (n = 185, mean BMI = 38.18 ± 6.17) and matched healthy-weight (n = 134, mean BMI = 22.35 ± 1.63) men (27.9%) and women (72.1%), aged 18-45 years, took part in the study. Participants were tested on several self-report and behavioral measures of impulsivity (i.e., response inhibition and reward sensitivity) and self-reported trait craving. In addition, they performed a visual search task to measure attentional bias for high- and low-caloric foods. Self-reported impulsivity influenced the relationship between weight status and detection speed of high- and low-caloric food items: High-impulsive participants with obesity were significantly faster than high-impulsive healthy-weight participants in detecting a high-caloric food item among neutral items, whereas no such difference was observed among low-impulsive participants. No significant effects were found on low-caloric food items, for trait craving or any of the behavioral measures of impulsivity. Self-reported impulsivity, but not trait craving or behavioral measures of impulsivity, is associated with an attentional bias for high-caloric foods, but only in people with obesity. It is in particular the speedy detection of high-caloric foods in the environment that characterizes the impulsive person with obesity, which in turn may cause risky eating patterns in a society were high-caloric food is overly present.

    2017-05-08

    Neuropsychological research can be advanced through a better understanding of relationships between executive functioning (EF) behavioral competencies and the expression of aggressive behavior. While performance-based EF measures have been widely examined, links between self-report indices and practical real-life outcomes have not yet been established. Executive Functioning Index subscale scores in this sample (N = 579) were linked to trait hostility (Buss-Perry Aggression Questionnaire), aggression in the natural environment (Lifetime Acts of Violence Assessment), and conduct disorder symptoms prior to age 15. Significant associations were found between all of the EFI subscales (Motivational Drive, Organization, Strategic Planning, Impulse Control, and Empathy), trait aggression, and conduct disturbance. Lifetime acts of aggression were predicted by all but Organization scores. Physical injuries inflicted on other(s) were 2 to 4 times more likely to occur among respondents generating low (z < -1) EFI subscale scores. While these EFI relationships were modest in size, they are pervasive in scope. These findings provide support for the potential role of perceived EF deficits in moderating lifetime aggression.

    To study the prevalence and correlates of self-reported ADHD symptoms among school-going adolescents from Kerala, India. Seven thousand five hundred sixty students from Classes 8, 10, and 12, aged 12 to 19 years, across 73 schools selected by cluster random sampling, were invited to participate, but only 7,150 successfully completed the questionnaire incorporating standardized instruments. Three hundred five (4.3%) self-reported symptoms for ADHD combined type, 131 (1.8%) for ADHD hyperactive-impulsive type, and 102 (1.4%) for ADHD inattentive type with a male predominance. Binary logistic regression analysis showed that those with symptoms of ADHD (combined type) compared with the non-ADHD group had poorer academic performance, significantly higher substance use, psychological distress, suicidality, and sexual abuse. The high prevalence of self-reported ADHD symptoms and its association with negative correlates previously reported in literature in those with a diagnosis of ADHD suggests that clinically significant self-reported ADHD symptoms could be as disabling as ADHD. © The Author(s) 2016.

  10. Facial Width-to-Height Ratio Does Not Predict Self-Reported Behavioral Tendencies.

    Kosinski, Michal

    2017-11-01

    A growing number of studies have linked facial width-to-height ratio (fWHR) with various antisocial or violent behavioral tendencies. However, those studies have predominantly been laboratory based and low powered. This work reexamined the links between fWHR and behavioral tendencies in a large sample of 137,163 participants. Behavioral tendencies were measured using 55 well-established psychometric scales, including self-report scales measuring intelligence, domains and facets of the five-factor model of personality, impulsiveness, sense of fairness, sensational interests, self-monitoring, impression management, and satisfaction with life. The findings revealed that fWHR is not substantially linked with any of these self-reported measures of behavioral tendencies, calling into question whether the links between fWHR and behavior generalize beyond the small samples and specific experimental settings that have been used in past fWHR research.

  11. A path model of different forms of impulsivity with externalizing and internalizing psychopathology: Towards greater specificity.

    Johnson, Sheri L; Tharp, Jordan A; Peckham, Andrew D; Carver, Charles S; Haase, Claudia M

    2017-09-01

    A growing empirical literature indicates that emotion-related impulsivity (compared to impulsivity that is unrelated to emotion) is particularly relevant for understanding a broad range of psychopathologies. Recent work, however, has differentiated two forms of emotion-related impulsivity: A factor termed Pervasive Influence of Feelings captures tendencies for emotions (mostly negative emotions) to quickly shape thoughts, and a factor termed Feelings Trigger Action captures tendencies for positive and negative emotions to quickly and reflexively shape behaviour and speech. This study used path modelling to consider links from emotion-related and non-emotion-related impulsivity to a broad range of psychopathologies. Undergraduates completed self-report measures of impulsivity, depression, anxiety, aggression, and substance use symptoms. A path model (N = 261) indicated specificity of these forms of impulsivity. Pervasive Influence of Feelings was related to anxiety and depression, whereas Feelings Trigger Action and non-emotion-related impulsivity were related to aggression and substance use. The findings of this study suggest that emotion-relevant impulsivity could be a potentially important treatment target for a set of psychopathologies. Recent work has differentiated two forms of emotion-related impulsivity. This study tests a multivariate path model linking emotion-related and non-emotion-related impulsivity with multiple forms of psychopathology. Impulsive thoughts in response to negative emotions were related to anxiety and depression. Impulsive actions in response to emotions were related to aggression and substance use, as did non-emotion-related impulsivity. The study was limited by the reliance on self-report measures of impulsivity and psychopathology. There is a need for longitudinal work on how these forms of impulsivity predict the onset and course of psychopathology. © 2017 The British Psychological Society.

    Full Text Available Objective: Impulsiveness has been the subject of much research, but little is known about the possible relationship between craniofacial anatomy and impulsiveness. The present study was designed to investigate the relationship between one aspect of craniofacial structure (the angle of inclination of the forehead and impulsiveness. Method: Photographs in profile were obtained from 131 volunteers who had been fined for driving at high speed and were undergoing a court-mandated driving license point-recovery course. They completed the Barratt Impulsiveness Scale (BIS-11, the Impulsive Behavior Scale (UPPS-P, and Zuckerman’s Sensation Seeking Scale (V. The angle of the slant of the forehead was measured with a photographic support and a protractor. Results: High positive concordance was found between forehead inclination and 14 out of the 15 impulsiveness factors studied. Conclusions: The angle of inclination of the forehead was significantly associated with self-reported impulsiveness in this sample of traffic violators.

  17. Lone-actor Terrorism and Impulsivity.

    Meloy, J Reid; Pollard, Jeffrey W

    2017-11-01

    In some recent cases of lone-actor terrorism, there is evidence the subject acted impulsively, often in response to a triggering event which contained a loss and humiliation. Evidence suggests the subjects acted precipitously, despite planning and preparation carried out in the preceding weeks or months, and their attacks failed to include the often considerable preparation that had been done. The pathway became a runway. The authors recommend the traditional assessment of impulsivity in persons of concern for lone acts of terrorism, as well as other proximal warning behaviors for targeted violence. Both indirect and direct assessment guidelines are proposed, with an emphasis upon self-report, psychological testing, collateral data gathering, and historical records. © 2017 American Academy of Forensic Sciences.

    Patients with psychotic disorders appear to exhibit greater impulsivity-related behaviors relative to healthy controls. However, the neural underpinning of this impulsivity remains uncertain. Furthermore, it remains unclear how impulsivity might differ or be conserved between psychotic disorder diagnoses in mechanism and manifestation. In this study, self-reported impulsivity, measured by Barratt Impulsiveness Scale (BIS), was compared between 305 controls (HC), 139 patients with schizophrenia (SZ), 100 with schizoaffective disorder (SZA), and 125 with psychotic bipolar disorder (PBP). In each proband group, impulsivity was associated with regional cortical volumes (using FreeSurfer analysis of T1 MRI scans), suicide attempt history, Global Assessment of Functioning (GAF), and Social Functioning Scale (SFS). BIS scores were found to differ significantly between participant groups, with SZA and PBP exhibiting significantly higher impulsivity than SZ, which exhibited significantly higher impulsivity than HC. BIS scores were significantly related to suicide attempt history, and they were inversely associated with GAF, SFS, and bilateral orbitofrontal cortex (OFC) volume in both SZA and PBP, but not SZ. These findings indicate that psychotic disorders, particularly those with prominent affective symptoms, are characterized by elevated self-reported impulsivity measures. Impulsivity's correlations with suicide attempt history, GAF, and SFS suggest that impulsivity may be a mediator of clinical outcome. The observed impulsivity-OFC correlations corroborate the importance of OFC deficits in impulsivity. These correlations' presence in SZA and PBP but not in SZ suggests that impulsivity may have different underlying mechanisms in affective and non-affective psychotic disorders.

  19. Impulsivity and Suicidality in Adolescent Inpatients.

    Auerbach, Randy P; Stewart, Jeremy G; Johnson, Sheri L

    2017-01-01

    Suicide is the second leading cause of death among adolescents, and impulsivity has emerged as a promising marker of risk. The present study tested whether distinct domains of impulsivity are differentially associated with suicide ideation, plans, and attempts. Adolescents (n = 381; boys = 106, girls = 275) aged 13-19 years (M = 15.62, SD = 1.41) were recruited from an acute, residential treatment program. Within 48 h of admission to the hospital, participants were administered structured clinical interviews assessing mental health disorders and suicidality. Following these interviews, participants completed self-report questionnaires assessing symptom severity and impulsivity. Consistent with past research, an exploratory factor analysis of our 90-item impulsivity instrument resulted in a three-factor solution: Pervasive Influence of Feelings, Feelings Trigger Action, and Lack of Follow-Through. Concurrent analysis of these factors confirmed hypotheses of unique associations with suicide ideation and attempts in the past month. Specifically, whereas Pervasive Influence of Feelings (i.e., tendency for emotions to shape thoughts about the self and the future) is uniquely associated with greater suicidal ideation, Feelings Trigger Action (i.e., impulsive behavioral reactivity to emotions) is uniquely associated with the occurrence of suicide attempts, even after controlling for current psychiatric diagnoses and symptoms. Exploratory gender analyses revealed that these effects were significant in female but not male adolescents. These findings provide new insight about how specific domains of impulsivity differentially increase risk for suicide ideation and attempts. Implications for early identification and prevention of youth suicide are discussed.

  20. Impression Management and Self-Report among Violent Offenders

    Mills, Jeremy F.; Kroner, Daryl G.

    2006-01-01

    Offenders are assumed by many to employ socially desirable responding (SDR) response styles when completing self-report measures. Contrary to expectations, prior research has shown that accounting for SDR in self-report measures of antisocial constructs does not improve the relationship with outcome. Despite this, many self-report measures…

  1. Accuracy of Professional Self-Reports: Medical Student Self-Report and the Scoring of Professional Competence

    Richter Lagha, Regina Anne

    2014-01-01

    Self-report is currently used as an indicator of professional practice in a variety of fields, including medicine and education. Important to consider, therefore, is the ability of self-report to accurately capture professional practice. This study investigated how well professionals' self-reports of behavior agreed with an expert observer's…

  2. Cognitive control in adolescence: neural underpinnings and relation to self-report behaviors.

    Jessica R Andrews-Hanna

    Full Text Available Adolescence is commonly characterized by impulsivity, poor decision-making, and lack of foresight. However, the developmental neural underpinnings of these characteristics are not well established.To test the hypothesis that these adolescent behaviors are linked to under-developed proactive control mechanisms, the present study employed a hybrid block/event-related functional Magnetic Resonance Imaging (fMRI Stroop paradigm combined with self-report questionnaires in a large sample of adolescents and adults, ranging in age from 14 to 25. Compared to adults, adolescents under-activated a set of brain regions implicated in proactive top-down control across task blocks comprised of difficult and easy trials. Moreover, the magnitude of lateral prefrontal activity in adolescents predicted self-report measures of impulse control, foresight, and resistance to peer pressure. Consistent with reactive compensatory mechanisms to reduced proactive control, older adolescents exhibited elevated transient activity in regions implicated in response-related interference resolution.Collectively, these results suggest that maturation of cognitive control may be partly mediated by earlier development of neural systems supporting reactive control and delayed development of systems supporting proactive control. Importantly, the development of these mechanisms is associated with cognitive control in real-life behaviors.

  3. The relations between personality traits and psychopathy as measured by ratings and self-report

    2015-01-01

    Full Text Available The objective of this study was to examine the relations between psychopathy - as assessed by ratings (PCL-R and by self-report (SRP3 - on one side, and The Five-Factor personality Model - expanded to include the traits Amorality and Disintegration - on the other. Both methods examined four traits of psychopathy: interpersonal, affective, lifestyle and antisocial characteristics. Data were collected on a sample of 112 male convicts. The results show the absence of congruence between the two methods - self-report and rating - in case of interpersonal and affective psychopathic dispositions. This incongruence is also reflected in their relations with personality traits. The self-report measures and the ratings of Lifestyle and Antisocial tendencies are related to amorality, aggressiveness, schizotypy, Neuroticism and impulsivity. However, the ratings of affective and interpersonal style are related to the integrated, organized, and emotionally stable aspects of personality. The results are interpreted in the light of differences between the methods of assessment and in the light of the essential characteristics of the psychopathic phenomena.

  4. Religiosity is a moderator of the relationship between impulsivity and internalizing symptoms

    JONAS JARDIM DE PAULA

    Full Text Available Abstract Background There is growing interest in the role of religion in psychiatric disorders. Impulsivity is a psychological trait associated with acting without thinking, with a decision process favoring short-term outcomes without further consideration of its consequences, and is a risk factor for the development of mental disorders. Objective In this study, the objective was to analyze the role of religiosity as a possible moderator between the association of impulsivity and internalizing psychiatric symptoms. Methods The hypothesis was assessed in a cross-sectional study enrolling 366 adults evaluated using the abbreviated version of the Barratt Impulsiveness Scale-11, the Self Reporting Questionnaire-20, and the Duke Religion Index. Results Internalizing symptoms were significantly influenced by an interaction between religiosity and impulsivity. Religiosity acted as a protective factor against internalizing symptoms only for participants with high impulsivity. Discussion The results suggest a moderation role of religiosity in the association of impulsivity with internalizing symptoms.

  5. The moderating role of social support on the relationship between impulsivity and suicide risk.

    Kleiman, Evan M; Riskind, John H; Schaefer, Karen E; Weingarden, Hilary

    2012-01-01

    Suicide is the second leading cause of death among college students. There has been considerable research into risk factors for suicide, such as impulsivity, but considerably less research on protective factors. The present study examines the role that social support plays in the relationship between impulsivity and suicide risk. Participants were 169 undergraduates who completed self-report measures of impulsivity and social support. Suicide risk was assessed using an interview measure. Social support moderates the relationship between impulsivity and suicide risk, such that those who are highly impulsive are less likely to be at risk for suicide if they also have high levels of social support. Social support can be a useful buffer to suicide risk for at-risk individuals who are highly impulsive.

  6. Impulsivity and test meal intake among women with bulimia nervosa.

    2017-05-01

    Many patients with bulimia nervosa (BN) also meet criteria for a lifetime alcohol use disorder (AUD). In order to understand possible mechanisms contributing to the co-occurrence and perpetuation of these disorders, this study investigated the importance of impulsivity and test meal intake among patients with BN by comparing women with BN only (n = 18), BN and current/past AUDs (n = 13), and healthy controls (n = 12). All participants completed assessments of eating disorder symptoms, frequency of alcohol use, binge eating, and purging via questionnaires and semi-structured interviews over two sessions. Measures of impulsivity consisted of computerized and self-report measures, and laboratory test meals. Significant differences between individuals with BN with/without comorbid AUDs were not found for test meal intake, impulsivity measures, or self-reported psychological symptoms. As hypothesized, compared to healthy controls, individuals with BN had significantly higher scores on two subscales and the total score of the Barratt Impulsiveness Scale, a trait measure of impulsivity, and consumed significantly more calories in the binge instruction meal. Total Barratt Impulsiveness Scale scores were also significantly related to kcal consumed during the laboratory test meal when individuals were instructed to binge eat (BN groups). Data from this study add to the existing literature implicating impulsivity in the psychopathology of disorders of binge eating, including BN, and also support the use of laboratory meals as a symptom-specific measure of this trait in eating disorder populations.

    Impulsive adolescents have difficulty quitting smoking. We examined if treatments that provide behavioral incentives for abstinence improve treatment outcomes among impulsive adolescent smokers, who have been shown to be highly sensitive to reward. We ran secondary data analyses on 64 teen smokers (mean age=16.36 [1.44]; cigarettes/day=13.97 [6.61]; 53.1% female; 90.6% Caucasian) who completed a four-week smoking cessation trial to determine whether impulsive adolescents differentially benefit from receiving cognitive behavioral therapy (CBT), contingency management (CM), or the combination of the two (CM/CBT). Indices of treatment efficacy included self-report percent days abstinent and end of treatment biochemically-confirmed 7-day point prevalence abstinence (EOT abstinence). We assessed self-reported impulsivity using the Brief Barratt Impulsiveness Scale. We used univariate Generalized Linear Modeling to examine main effects and interactions of impulsivity and treatment condition as predictors of self-reported abstinence, and exact logistic regression to examine EOT abstinence. CM/CBT and CM were comparably effective in promoting abstinence, so analyses were conducted comparing the efficacy of CBT to treatments with a CM component (i.e., CM and CM/CBT). CBT and deficient self-regulation predicted lower self-reported abstinence rates within the total analytic sample. Treatments containing CM were more effective than CBT in predicting 1) self-reported abstinence among behaviorally impulsive adolescents (% days abstinent: CM 77%; CM/CBT 81%; CBT 30%) and 2) EOT point prevalence abstinence among behaviorally impulsive adolescents and adolescents with significant deficits in self-regulation. CM-based interventions may improve the low smoking cessation rates previously observed among impulsive adolescent smokers. Copyright © 2014 Elsevier Ltd. All rights reserved.

  9. Rethinking Impulsivity in Suicide

    Klonsky, E. David; May, Alexis

    2010-01-01

    Elevated impulsivity is thought to facilitate the transition from suicidal thoughts to suicidal behavior. Therefore, impulsivity should distinguish those who have attempted suicide (attempters) from those who have only considered suicide (ideators-only). This hypothesis was examined in three large nonclinical samples: (1) 2,011 military recruits,…

    Full Text Available The main purpose of this study was to investigate the psychometric properties of the Barratt Impulsiveness Scale (BIS-11. Content item analysis was conducted by seven doctoral students. A convenience sample of 897 students was submitted to BIS-11 and they also filled self-reports about Minor Mental Disorder and ADHD symptoms, alcohol use and cigarette smoking. Mean age was 27.32 (SD=8.69 years, 56% were female and 52% had incomplete college degree. Content and factorial analyses revealed that impulsivity was best represented by two latent factors labeled non-planning and inhibition behaviors. Test retest agreement tended to produce similar score patterns seven months after the first evaluation. Additionally, BIS-11 scores discriminated subjects in terms of cigarette smoking and psychopathological symptoms, which indicated evidences regarding criterion-related validity. The theoretical discussion was present based on the neuropsychological model of hot and cool aspects of executive function.

  11. Impulsivity, Working Memory, and Impaired Control over Alcohol: A Latent Variable Analysis

    Wardell, Jeffrey D.; Quilty, Lena C.; Hendershot, Christian S.

    2017-01-01

    Impaired control over alcohol is an important risk factor for heavy drinking among young adults and may mediate, in part, the association between personality risk and alcohol problems. Research suggests that trait impulsivity is associated with impaired control over alcohol; however, few studies of this association have included a range of impulsivity facets. The purpose of this study was to examine specific pathways from higher-order impulsivity factors to alcohol problems mediated via impaired control over alcohol. We also examined the moderating role of working memory in these associations. Young heavy drinkers (N=300) completed two multidimensional impulsivity measures (UPPS-P and BIS-11) along with self-report measures of impaired control over alcohol, alcohol use, and alcohol problems. Working memory was assessed using a computerized digit span task. Results showed that the impulsivity facets loaded onto two higher-order factors that were labeled response and reflection impulsivity. Response impulsivity predicted unique variance in self-reported impaired control and alcohol problems, whereas reflection impulsivity predicted unique variance in heavy drinking frequency only. Further, significant indirect associations were observed from response and reflection impulsivity to alcohol problems mediated via impaired control and heavy drinking frequency, respectively. Working memory and sensation seeking were not uniquely associated with the alcohol variables, and no support was found for the moderating role of working memory. The results help to clarify associations among impulsivity, impaired control, and alcohol problems, suggesting that impaired control may play a specific role in the pathway to alcohol problems from response impulsivity but not from reflection impulsivity.

  12. An examination of the relationship between measures of impulsivity and risky simulated driving amongst young drivers.

    Hatfield, Julie; Williamson, Ann; Kehoe, E James; Prabhakharan, Prasannah

    2017-06-01

    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 impulsivity was measured by means of the Barratt Impulsivity Scale, version 11 (BIS-11, a widely used self-report questionnaire, and the platelet SERT was evaluated by means of the specific binding of 3H-paroxetine (3H-Par to platelet membranes, according to standardized protocols. The results showed that women had a higher BIS-11 total score than men, and also higher scores of two factors of the same scale: the motor impulsivity and the cognitive complexity. The analysis of the correlations revealed that the density of the SERT proteins, as measured by the maximum binding capacity (Bmax of 3H-Par, was significantly and positively related to the cognitive complexity factor, but only in men. Men showed also a significant and negative correlation with the dissociation constant, Kd, of (3H-Par binding, and the motor impulsivity factor. These findings suggest that women are generally more impulsive than men, but that the 5-HT system is more involved in the impulsivity of men than in that of women.Keywords: impulsivity, gender, serotonin transporter, Barratt Impulsivity Scale, platelets, 3H-paroxetine

  14. The error-related negativity (ERN is an electrophysiological marker of motor impulsiveness on the Barratt Impulsiveness Scale (BIS-11 during adolescence

    Jasmine B. Taylor

    2018-04-01

    Full Text Available Objectives: Previous studies have postulated that the error-related negativity (ERN may reflect individual differences in impulsivity; however, none have used a longitudinal framework or evaluated impulsivity as a multidimensional construct. The current study evaluated whether ERN amplitude, measured in childhood and adolescence, is predictive of impulsiveness during adolescence. Methods: Seventy-five children participated in this study, initially at ages 7–9 years and again at 12–18 years. The interval between testing sessions ranged from 5 to 9 years. The ERN was extracted in response to behavioural errors produced during a modified visual flanker task at both time points (i.e. childhood and adolescence. Participants also completed the Barratt Impulsiveness Scale − a measure that considers impulsiveness to comprise three core sub-traits − during adolescence. Results: At adolescence, the ERN amplitude was significantly larger than during childhood. Additionally, ERN amplitude during adolescence significantly predicted motor impulsiveness at that time point, after controlling for age, gender, and the number of trials included in the ERN. In contrast, ERN amplitude during childhood did not uniquely predict impulsiveness during adolescence. Conclusions: These findings provide preliminary evidence that ERN amplitude is an electrophysiological marker of self-reported motor impulsiveness (i.e. acting without thinking during adolescence.

    Full Text Available Objective:Compulsive buying is controversial in clinical psychiatry. Although it is defined as an obsessive-compulsive disorder, other personality aspects besides compulsivity are related to compulsive buying. Recent studies suggest that compulsivity and impulsivity might represent a continuum, with several psychiatric disorders lying between these two extremes. In this sense, and following the perspective of dimensional psychiatry, symptoms of impulsivity and compulsivity should correlate even in a non-clinical sample. The present study aims to investigate whether these two traits are associated in a healthy adult sample.Methods:We evaluated 100 adults, with no self-reported psychiatric disorders, using the Barratt Impulsiveness Scale-11 and two scales of compulsive buying.Results:Using multiple linear regressions, we found that impulsivity accounted for about 15% of variance in the compulsive-buying measure.Conclusions:Our results suggest that an association between impulsivity and compulsive buying occurs even in non-clinical samples, evidence that compulsivity and impulsivity might form a continuum and that compulsive buying might be an intermediate condition between these two personality traits.

  19. Validation of Self-Reported Cognitive Problems with Objective ...

    There is a lack of validation of self-reported cognitive problems with objective neuropsychological measures. The validity of four self-reported cognitive items from a health questionnaire (HQ) and the Symptoms Checklist 90-Revised (SCL-90-R) was examined with objective clinical neuropsychological test performance in 147 manganese (Mn) exposed residents. These residents were from two Ohio towns exposed to ambient air-Mn from an industrial source with modeled average air-Mn concentrations of 0.54 µg/m3 (range: 0.01-4.58) and were part of a larger study of cognitive, motor, tremor abnormalities and their relationship to Mn exposure.The primarily white (94.6%) participants (aged 30-64) lived in the towns for at least 10 years (range: 10-64) and had 13.9 years of education, on average. In the last 7 days before testing, 94 (64.4%) participants self-reported concentration problems and 105 (71.8%) self-reported memory problems. After adjusting for age and education, participants who self-reported cognitive problems did not perform worse on the objective neuropsychological measures than those who reported not having problems, except on 1 of 17 neuropsychological tests (Stroop Color). Greater levels of depression and female sex predicted having more self-reported cognitive problems. Higher education was associated with fewer self-reported cognitive problems. Measures of Mn in air, blood, hair, and toenails were not associated with subjective cognitive self-reported p

    Here, we review the evidence for sex differences in behavioral measures of impulsivity for both humans and laboratory animals. We focus on two specific components of impulsivity: impulsive action (i.e., difficulty inhibiting a prepotent response) and impulsive choice (i.e., difficulty delaying gratification). Sex differences appear to exist on these measures, but the direction and magnitude of the differences vary. In laboratory animals, impulsive action is typically greater in males than fem...

    A number of methods exist for estimating the size of animal populations. All methods generate an uncertain estimate of population size, and have different properties, which can be taken into account when designing regulation. We consider hunting regulation when the population size is uncertain...... and when the self-reported bag is used to estimate the population size. The properties of a population tax and a tax on self-reported bag are analyzed and we begin by considering a baseline situation with full certainty and no use of self-reporting for population size estimation. Here individual hunters...... self-report a bag on zero and a population tax alone can secure an optimum. Next we show that when facing uncertain population size, a risk-averse hunter will self-report part of the bag to reduce the uncertain population tax payment, making both tax instruments necessary for reaching an optimum...

  2. Association between chronic urticaria and self-reported penicillin allergy.

    Silverman, Susanna; Localio, Russell; Apter, Andrea J

    2016-04-01

    Penicillin allergy is the most commonly reported drug allergy and often presents with cutaneous symptoms. Other common diagnoses, such as chronic urticaria, may be falsely attributed to penicillin allergy. Because chronic urticaria is fairly common in the general population, evaluation of its prevalence in patients with self-reported penicillin allergy was of interest. Similarly, the prevalence of self-reported penicillin allergy in patients with chronic urticaria is not well known and also becomes interesting in light of the high prevalence of self-reported penicillin allergy in the general population. To determine the prevalence of self-reported penicillin allergy in patients with chronic urticaria and the prevalence of chronic urticaria in patients with self-reported penicillin allergy. This was a retrospective medical record review of 11,143 patients completed using the electronic health record of the University of Pennsylvania Allergy and Immunology clinic. The prevalence of self-reported penicillin allergy in patients with chronic urticaria was found to be approximately 3 times greater than in the general population. The prevalence of chronic urticaria in patients with self-reported penicillin allergy was also found to be approximately 3 times greater than in the population. This link between chronic urticaria and self-reported penicillin allergy highlights the need for clinicians to inquire about self-reported penicillin allergy in patients with chronic urticaria and to consider penicillin skin testing. Furthermore, patients who report penicillin allergy might actually have chronic urticaria, indicating the importance of inquiring about chronic urticaria symptoms in patients with self-reported penicillin allergy.

  3. Convergent and Discriminant Validity of Psychopathy Factors Assessed Via Self-Report

    Benning, Stephen D.; Patrick, Christopher J.; Salekin, Randall T.; Leistico, Anne-Marie R.

    2008-01-01

    Psychopathy has been conceptualized as a personality disorder with distinctive interpersonal-affective and behavioral deviance features. The authors examine correlates of the factors of the Psychopathic Personality Inventory (PPI), Self-Report Psychopathy–II (SRP-II) scale, and Antisocial Process Screening Device (APSD) to understand similarities and differences among the constructs embodied in these instruments. PPI Fearless Dominance and SRP-II Factor 1 were negatively related to most personality disorder symptoms and were both predicted by high Dominance and low Neuroticism. In addition, PPI Fearless Dominance correlated positively with antisocial personality features, although SRP-II Factor 1 did not. In contrast, PPI Impulsive Antisociality, SRP-II Factor 2, and both APSD factors correlated with antisocial personality features and symptoms of nearly all personality disorders, and were predicted by low Love. Results suggest ways in which the measurement of the constructs in each instrument may be improved. PMID:16123248

  4. Impulsivity and suicidality: the mediating role of painful and provocative experiences.

    Bender, Theodore W; Gordon, Kathryn H; Bresin, Konrad; Joiner, Thomas E

    2011-03-01

    Multiple studies have reported a link between high levels of impulsivity and suicidal behavior. Joiner's (2005) explanation for this link is that impulsive individuals have a greater tendency to experience painful and provocative events that habituate them to fear and pain, which leads to an acquired capability for engaging in suicidal behavior. Study 1 tested Joiner's (2005) hypothesis in a sample of 182 undergraduate students who completed self-report questionnaires on impulsivity, frequency of painful and provocative events, and acquired capability for suicide. In addition to self-report, pain tolerance (an aspect of acquired capability for suicide) was measured with a pressure algometer. Study 2 sought to replicate our findings from Study 1 in a sample of 516 clinical outpatients using a multi-faceted measure of impulsivity. Consistent with prediction, product of coefficients tests for mediation (MacKinnon et al., 2002) revealed that impulsivity has an indirect relationship with acquired capability for suicidal behavior, and that this relationship is mediated by painful and provocative events. Data from our studies are cross-sectional in nature, which does not allow for conclusions about the temporal ordering of our variables. In addition, self-report was used to measure most variables. Future research may benefit from a longitudinal design and the inclusion of other modes of assessment (e.g., behavioral measures of impulsivity). Our findings suggest that the link between impulsivity and suicidal behavior occurs because impulsive people tend to have a greater capability for suicidal behavior, which they have acquired through experiencing painful and provocative events.

  5. Neural Correlates of Impulsivity in Healthy Males and Females with Family Histories of Alcoholism

    DeVito, Elise E; Meda, Shashwath A; Jiantonio, Rachel; Potenza, Marc N; Krystal, John H; Pearlson, Godfrey D

    2013-01-01

    Individuals family-history positive (FHP) for alcoholism have increased risk for the disorder, which may be mediated by intermediate behavioral traits such as impulsivity. Given the sex differences in the risk for and clinical presentation of addictive disorders, risk for addiction may be differentially mediated by impulsivity within FHP males and females. FHP (N=28) and family-history negative (FHN, N=31) healthy, non-substance-abusing adults completed an fMRI Go/No-Go task and were assessed on impulsivity and alcohol use. Effects of family history and sex were investigated as were associations between neural correlates of impulse control and out-of-scanner measures of impulsivity and alcohol use. FHP individuals showed greater activation in the left anterior insula and inferior frontal gyrus during successful inhibitions, an effect that was driven primarily by FHP males. Higher self-reported impulsivity and behavioral discounting impulsivity, but not alcohol use measures, were associated with greater BOLD signal in the region that differentiated the FHP and FHN groups. Impulsivity factors were associated with alcohol use measures across the FHP and FHN groups. These findings are consistent with increased risk for addiction among FHP individuals being conferred through disrupted function within neural systems important for impulse control. PMID:23584260

  10. Food-cue affected motor response inhibition and self-reported dieting success: a pictorial affective shifting task

    Adrian eMeule

    2014-03-01

    Full Text Available Behavioral inhibition is one of the basic facets of executive functioning and is closely related to self-regulation. Impulsive reactions, i.e. low inhibitory control, have been associated with higher body-mass-index (BMI, binge eating, and other problem behaviors (e.g. substance abuse, pathological gambling, etc.. Nevertheless, studies which investigated the direct influence of food-cues on behavioral inhibition have been fairly inconsistent. In the current studies, we investigated food-cue affected behavioral inhibition in young women. For this purpose, we used a go/no-go task with pictorial food and neutral stimuli in which stimulus-response mapping is reversed after every other block (affective shifting task. In study 1, hungry participants showed faster reaction times to and omitted fewer food than neutral targets. Low dieting success and higher BMI were associated with behavioral disinhibition in food relative to neutral blocks. In study 2, both hungry and satiated individuals were investigated. Satiation did not influence overall task performance, but modulated associations of task performance with dieting success and self-reported impulsivity. When satiated, increased food craving during the task was associated with low dieting success, possibly indicating a preload-disinhibition effect following food intake. Food-cues elicited automatic action and approach tendencies regardless of dieting success, self-reported impulsivity, or current hunger levels. Yet, associations between dieting success, impulsivity, and behavioral food-cue responses were modulated by hunger and satiation. Future research investigating clinical samples and including other salient non-food stimuli as control category is warranted.

A better understanding of self-injury comorbidities is crucial to improve our ability to assess, treat, and prevent NSSI.Purpose: This study aimed at analyzing some of the psychobehavioral correlates of NSSI: psychological problems, alexithymia, impulsiveness, and sociorelational aspects.Patients and methods: This was a case–control study. The clinical sample (n=33 included adolescents attending our unit for NSSI and other issues; the controls (n=79 were high-school students. Data were collected using six questionnaires: Youth Self-Report, Barratt’s Impulsiveness Scale, Toronto Alexithymia Scale, Children’s Depression Inventory, Symptom Checklist-90-R, and Child Behavior Checklist.Results: Cases scored significantly higher in all questionnaires. Habitual self-injurers scored higher on impulsiveness and alexithymia. The gesture’s repetition seems relevant to the global clinical picture: habitual self-injurers appear more likely to seek help from the sociosanitary services. We found a difference between the self-injurers’ and their parents’ awareness of the disorder.Conclusion: Habitual self-injurers show signs of having difficulty with assessing the consequences of their actions (nonplanning impulsiveness and the inability to manage their feelings. Given the significantly higher scores found for cases than for controls on all the psychopathological scales, NSSI can be seen as a cross-category psychiatric disorder, supporting the Diagnostic and Statistical Manual of Mental Disorders decision to include it as a pathological entity in its own right.

  12. Impulsive action and motivation.

    Frijda, Nico H

    2010-07-01

    This paper explores the way in which emotions are causal determinants of action. It argues that emotional events, as appraised by the individual, elicit changes in motive states (called states of action readiness), which in turn may (or may not) cause action. Actions can be elicited automatically, without prior intention (called impulsive actions), or intentionally. Impulsive actions reflect the simplest and biologically most general form in which emotions can cause action, since they require no reflection, no foresight, and no planning. Impulsive actions are determined conjointly by the nature of action readiness, the affordances perceived in the eliciting event as appraised, and the individual's action repertoire. Those actions from one's repertoire are performed that both match the perceived affordances and the aim of the state of action readiness. Copyright © 2010 Elsevier B.V. All rights reserved.

  15. Do aggressive driving and negative emotional driving mediate the link between impulsiveness and risky driving among young Italian drivers?

    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.

  16. Sex differences in impulsive action and impulsive choice.

    Weafer, Jessica; de Wit, Harriet

    2014-11-01

    Here, we review the evidence for sex differences in behavioral measures of impulsivity for both humans and laboratory animals. We focus on two specific components of impulsivity: impulsive action (i.e., difficulty inhibiting a prepotent response) and impulsive choice (i.e., difficulty delaying gratification). Sex differences appear to exist on these measures, but the direction and magnitude of the differences vary. In laboratory animals, impulsive action is typically greater in males than females, whereas impulsive choice is typically greater in females. In humans, women discount more steeply than men, but sex differences on measures of impulsive action depend on tasks and subject samples. We discuss implications of these findings as they relate to drug addiction. We also point out the major gaps in this research to date, including the lack of studies designed specifically to examine sex differences in behavioral impulsivity, and the lack of consideration of menstrual or estrous phase or sex hormone levels in the studies. © 2013.

  17. Ballistic impulse gauge

    Ault, Stanley K.

    1993-01-01

    A gauge for detecting the impulse generated in sample materials by X-rays or other impulse producing mechanisms utilizes a pair of flat annular springs to support a plunger relative to a housing which may itself be supported by a pair of flat annular springs in a second housing. The plunger has a mounting plate mounted on one end and at the other, a position or velocity transducer is mounted. The annular springs consist of an outer ring and an inner ring with at least three arcuate members connecting the outer ring with the inner ring.

  19. Relativistic impulse dynamics.

    Swanson, Stanley M

    2011-08-01

    Classical electrodynamics has some annoying rough edges. The self-energy of charges is infinite without a cutoff. The calculation of relativistic trajectories is difficult because of retardation and an average radiation reaction term. By reconceptuallizing electrodynamics in terms of exchanges of impulses rather than describing it by forces and potentials, we eliminate these problems. A fully relativistic theory using photonlike null impulses is developed. Numerical calculations for a two-body, one-impulse-in-transit model are discussed. A simple relationship between center-of-mass scattering angle and angular momentum was found. It reproduces the Rutherford cross section at low velocities and agrees with the leading term of relativistic distinguishable-particle quantum cross sections (Møller, Mott) when the distance of closest approach is larger than the Compton wavelength of the particle. Magnetism emerges as a consequence of viewing retarded and advanced interactions from the vantage point of an instantaneous radius vector. Radiation reaction becomes the local conservation of energy-momentum between the radiating particle and the emitted impulse. A net action is defined that could be used in developing quantum dynamics without potentials. A reinterpretation of Newton's laws extends them to relativistic motion.

  20. Recreational drug use and impulsivity in a population of Canadian undergraduate drinkers

    Iris M Balodis

    2010-10-01

    Full Text Available The consumption of drugs during young adulthood may be particularly detrimental given important neurodevelopmental changes occurring during this period. As impulsivity may lead to substance use and substance use to the commission of seemingly impulsive acts, an improved understanding of the relationship between alcohol use, other substance use and impulsivity in young adults is important. We gathered information on self-reported impulsivity, recreational drug use, and drinking habits of 205 (105 female undergraduate students. Results showed that 64% of the students reported using marijuana at least once and these individuals were more likely to report binge drinking. Polydrug use, defined as using marijuana and at least one other illicit substance, was reported by 20% of students. These individuals reported more drinking occasions per month and had higher levels of trait impulsivity. Rates of recreational drug use were similar to those reported in recent national surveys, suggesting an increase in experimentation with specific illicit drugs. Given that a majority of undergraduate drinkers reported marijuana use and its association with binge drinking, future research should clarify the relationship between marijuana use and binge consumption of alcohol and prevention efforts should consider the conjoint targeting of marijuana and binge drinking. The associations between polydrug use, binge-level alcohol consumption and elevated self-reported impulsivity suggests that perceived trait impulsivity across multiple domains may predispose to excessive use of multiple substances. Longitudinal studies should examine the contribution of impulsivity to the initiation and experimentation with illicit drugs and the influence of specific substances on impulsivity.

  1. Relationship between anhedonia and impulsivity in schizophrenia, major depression and schizoaffective disorder.

    Amr, Mostafa; Volpe, Fernando Madalena

    2013-12-01

    Anhedonia and impulsivity are prominent symptoms of many psychiatric disorders and may indicate worse prognosis, notably in schizophrenia and major depression. Despite the convergence of negative outcomes from both dimensions, the relationship between anhedonia and impulsivity in psychiatric disorders has been seldom directly assessed. The objective of the present study is to examine the correlations between anhedonia and impulsivity in three diagnostic groups: major depression, schizophrenia and schizoaffective disorder. 121 outpatients (Mansoura University Hospital, Egypt) with major depressive disorder (N=29), schizophrenia (N=59), and schizoaffective disorder (N=33), were assessed and responded to the Beck Depression Inventory, Barrat's Impulsivity Scale-11, and Chapman's Social and Physical Anhedonia Scales. Physical and social anhedonia scores were negatively correlated to impulsivity scores in major depression patients. Conversely, higher scores in physical and social anhedonia predicted higher impulsivity scores in schizophrenia. No correlations between impulsivity and anhedonia were evidenced among schizoaffectives. The relationship between self-reported physical and social anhedonia and impulsivity is diagnosis-specific.

  2. Sleep Characteristics of Self-Reported Long Sleepers

    Patel, Sanjay R.; Blackwell, Terri; Ancoli-Israel, Sonia; Stone, Katie L.

    2012-01-01

    Background: Self-reported long habitual sleep durations (≥ 9 h per night) consistently predict increased mortality. We compared objective sleep parameters of self-reported long versus normal duration sleepers to determine whether long sleepers truly sleep more or have an underlying sleep abnormality. Methods: Older men participating in the Osteoporotic Fractures in Men Study (MrOS) were recruited for a comprehensive sleep assessment, which included wrist actigraphy, overnight polysomnography (PSG), and a question about usual nocturnal sleep duration. Results: Of the 3134 participants (mean age 76.4 ± 5.6; 89.9% Caucasian), 1888 (60.2%) reported sleeping 7-8 h (normal sleepers) and 174 (5.6%) reported ≥ 9 h (long sleepers). On actigraphy, long sleepers spent on average 63.0 min more per night in bed (P sleep stage distribution did not differ. After adjusting for differences in demographics, comorbidities, and medication usage, self-reported long sleepers continued to spend more time in bed and sleep more, based on both actigraphy and PSG. Each additional 30 min in bed or asleep as measured by actigraphy increased the odds of being a self-reported long-sleeper 1.74-fold and 1.33-fold, respectively (P sleep disorders.

  3. Occlusal factors are not related to self-reported bruxism.

    2012-01-01

    To estimate the contribution of various occlusal features of the natural dentition that may identify self-reported bruxers compared to nonbruxers. Two age- and sex-matched groups of self-reported bruxers (n = 67) and self-reported nonbruxers (n = 75) took part in the study. For each patient, the following occlusal features were clinically assessed: retruded contact position (RCP) to intercuspal contact position (ICP) slide length ( 4 mm, a deep bite), horizontal overlap (> 4 mm was considered a large horizontal overlap), incisor dental midline discrepancy (bruxism (dependent variable). Accuracy values to predict self-reported bruxism were unacceptable for all occlusal variables. The only variable remaining in the final regression model was laterotrusive interferences (P = .030). The percentage of explained variance for bruxism by the final multiple regression model was 4.6%. This model including only one occlusal factor showed low positive (58.1%) and negative predictive values (59.7%), thus showing a poor accuracy to predict the presence of self-reported bruxism (59.2%). This investigation suggested that the contribution of occlusion to the differentiation between bruxers and nonbruxers is negligible. This finding supports theories that advocate a much diminished role for peripheral anatomical-structural factors in the pathogenesis of bruxism.

  4. Sexual Orientation, Objective Height, and Self-Reported Height.

    Skorska, Malvina N; Bogaert, Anthony F

    2017-01-01

    Studies that have used mostly self-reported height have found that androphilic men and women are shorter than gynephilic men and women, respectively. This study examined whether an objective height difference exists or whether a psychosocial account (e.g., distortion of self-reports) may explain these putative height differences. A total of 863 participants, recruited at a Canadian university, the surrounding region, and through lesbian, gay, bisexual, and transgender (LGBT) events across Canada, self-reported their height and had their height measured. Androphilic men were shorter, on average, than gynephilic men. There was no objective height difference between gynephilic, ambiphilic, and androphilic women. Self-reported height, statistically controlling for objective height, was not related to sexual orientation. These findings are the first to show an objective height difference between androphilic and gynephilic men. Also, the findings suggest that previous studies using self-reported height found part of a true objective height difference between androphilic and gynephilic men. These findings have implications for existing biological theories of men's sexual orientation development.

    2012-03-01

    Women constitute only a small proportion of inmates, but several studies have shown that they have higher rates of psychiatric disturbance than incarcerated men and community samples. Mental health treatment is necessary to prevent severe illness and suicide in these women. The convenience sample consisted of 40 female detainees and 40 controls who were administered self-report questionnaires to assess temperament (TEMPS-A), insecure attachment (ECR), impulsivity (BIS-11), and sexual behavior (SESAMO). The incarcerated women had higher levels of affective temperament (except for hyperthymia), avoidance, anxiety, impulsivity, and psychosexual issues than the female community sample. Many interrelated emotional and affective disturbances affect the physical and psychological well-being of women in jail, and it is possible that these problems may lead to suicide. Health professionals need to develop gender-specific therapeutic interventions for women in jail. © 2012 International Association of Forensic Nurses.

  6. The temporal course and clinical correlates of subjective impulsivity in bipolar disorder as revealed through ecological momentary assessment.

    Depp, Colin A; Moore, Raeanne C; Dev, Sheena I; Mausbach, Brent T; Eyler, Lisa T; Granholm, Eric L

    2016-03-15

    Impulsivity is frequently linked with bipolar disorder and is associated with mania and negative outcomes. The temporal dynamics of subjective impulsivity are unclear, in particular whether impulsivity precedes or follows changes in positive or negative affect. A total of 41 outpatients with bipolar disorder (I or II) were provided with mobile devices for 11 weeks and completed twice-daily surveys about affective states and subjective impulsivity. We examined the association between aggregate subjective impulsivity with baseline global cognitive function, suicide risk ratings, and medication adherence, as well as concurrent and lagged associations with momentary positive and negative affect ratings. A total of 2902 ratings were available across study subjects. Higher aggregate mean ratings of impulsivity were associated with worse baseline global cognitive function, prior suicide attempts, and self-reported problems with medication adherence, as well as more severe manic (but not depressive) symptoms. Time-lagged models indicated that greater negative affect, but not positive affect, predicted subsequent increases in subjective impulsivity, which, in turn, predicted diminished positive affect. Other measures of impulsivity with which to validate subjective ratings were unavailable and the sample was restricted to generally clinically stable outpatients. Subjective impulsivity as measured by daily monitoring was associated with worse cognitive function and self-rated medication adherence, and higher suicide risk ratings. Impulsivity may be a maladaptive strategy to regulate negative affect in bipolar disorder. Copyright © 2016. Published by Elsevier B.V.

  7. Sex differences in same-sex direct aggression and sociosexuality: the role of risky impulsivity.

    Cross, Catharine P

    2010-12-23

    Sex differences in same-sex direct aggression and sociosexuality are among the most robust in the literature. The present article evaluated the hypothesis that both can be explained by a sex difference in the willingness to take impulsive risks. Self-report data were gathered from 3,775 respondents (1,514 female) on same-sex aggression, sociosexuality, and risky impulsivity. Risky impulsivity was higher for men than for women (d = .34) and path analysis showed it to be a common cause of same-sex aggression and sociosexuality for both sexes. However, it did not completely mediate the sex differences in same-sex aggression and sociosexuality. The results suggest that same-sex aggression and sociosexual behavior share a common psychological mechanism, but that fully explaining sex differences in aggression requires a more sensitive assay of impulsive risk and a consideration of dyadic processes.

    The characteristics of impact fusion energy releases are not known sufficiently well to examine in detail specific containment vessel concepts or designs. Therefore it appears appropriate to formulate the impulse containment problem in general and to derive results in the form of explicit expressions from which magnitude estimates and parametric dependencies (trends) can be inferred conveniently and rapidly.

  11. Latent class analysis of eating and impulsive behavioral symptoms in Taiwanese women with bulimia nervosa.

    Tseng, Mei-Chih Meg; Hu, Fu-Chang

    2012-01-01

    The implications of impulsivity in its relationship with binge-eating or purging behaviors remain unclear. This study examined the patterns of eating behaviors and co-morbid impulsive behaviors in individuals with bulimia nervosa n optimally homogeneous classes using latent class analysis (LCA). All participants (n=180) were asked to complete a series of self-reported inventories of impulsive behaviors and other psychological measures. Information regarding the lifetime presence of symptoms of eating disorder was assessed by clinical interviews. LCA was conducted using eating disorder symptoms, impulsive behaviors, and the number of purging methods. Three latent classes of bulimic women were identified. These were women who exhibited relatively higher rates of purging, symptoms of impulsive behavior, and multiple purging methods (17.8%), women who used no more than one purging method with a low occurrence of impulsive behavior (41.7%), and women who showed higher rates of purging behaviors and the use of multiple purging methods with a low rate of impulsive behavior (41.7%). The impulsive sub-group had comparable severity of eating-related measures, frequency of binge-eating, and higher levels of general psychopathology than that of the other two sub-groups. This study provides empirical support for the existence of an impulsive subgroup with distinctive features among a non-Western group of BN patients. This study also suggests that mechanisms other than impulse dysregulation may exist for the development of binge-eating and purging behaviors in bulimia nervosa patients, or the mechanisms contributing to binge-eating and impulsive behaviors may be different.

  12. Alcohol use and drunk driving: the modifying effect of impulsivity.

    Moan, Inger Synnøve; Norström, Thor; Storvoll, Elisabet E

    2013-01-01

    The aim of this study was twofold: (a) to examine how an increase in the frequency of heavy drinking episodes affects the incidence of drunk driving and (b) to examine whether the effect of alcohol use on drunk driving is contingent on impulsivity. Two waves of the Young in Norway Longitudinal Study were applied (N = 2,603; response rate: 67%), when the respondents were on average 17 (1994) and 28 (2005) years of age. Measurements consisted of self-reported heavy episodic drinking, drunk driving, and impulsivity. The first difference method was applied to estimate the association between heavy episodic drinking and drunk driving. This means that changes in the frequency of drunk driving were regressed on changes in the frequency of drinking. In this way, the effects of time-invariant confounders were eliminated. The results showed that every additional episode of heavy drinking was associated with a 2.6% increase in the frequency of drunk driving. The increase for males was significantly higher than among females. The analyses supported the hypothesis that impulsivity modifies the association between alcohol use and drunk driving. The association between drinking and drunk driving is significantly stronger among those with a high score on impulsivity compared with those who have a low score.

  13. [Emotional and impulsive dimensions in bipolar disorder and borderline personality disorder].

    Leblanc, A; Jarroir, M; Vorspan, F; Bellivier, F; Leveillee, S; Romo, L

    2017-05-01

    Studies have shown that patients with borderline personality disorder are often misdiagnosed to have bipolar disorder and conversely. Indeed, a number of characteristics common to both disorders could explain this problem: emotional instability as well as impulsivity represent confounding factors and contribute to the risk of misdiagnosis. However, it appears that these characteristics manifest themselves in different ways according to the pathology. The aim of the study is to show differences between affective lability, emotional intensity and impulsivity dimensions. The clinical aim is to refine bipolar disorder and borderline personality disorder diagnosis, to improve psychological care for these patients in the long-term. We compared the emotional and impulsive dimensions in two groups of patients: a group of 21 patients with bipolar disorder and a group of 19 patients with borderline personality disorder. Tools: ALS, a self-report questionnaire to evaluate affective lability, AIM, a self-report questionnaire to see affective intensity, and UPPS, a self-report questionnaire to measure impulsivity according to several dimensions. The results indicate that borderline patients scored significantly higher than bipolar patients at the ALS and AIM scales. Regarding the UPPS, borderline patients scored significantly higher than bipolar patients for the dimensions "lack of premeditation" and "lack of perseverance"; however, bipolar patients had significantly higher scores than borderline patients for the dimension "negative emergency". This study shows that bipolar disorder and borderline personality can be differentiated thanks to emotional dimensions as well as different dimensions of impulsivity: borderline patients appear to have an affective lability and intensity more important than bipolar patients; it also appears that impulsivity manifests itself differently according to the disorder.

  14. Fatty acid amide supplementation decreases impulsivity in young adult heavy drinkers

    van Kooten, Maria J.; Veldhuizen, Maria G.; de Araujo, Ivan E.; O’Malley, Stephanie; Small, Dana M.

    2016-01-01

    Compromised dopamine signaling in the striatum has been associated with the expression of impulsive behaviors in addiction, obesity and alcoholism. In rodents, Intragastric infusion of the fatty acid amide oleoylethanolamide increases striatal extracellular dopamine levels via vagal afferent signaling. Here we tested whether supplementation with PhosphoLean™, a dietary supplement that contains the precursor of the fatty acid amide oleoylethanolamide (N-oleyl-phosphatidylethanolamine), would reduce impulsive responding and alcohol use in heavy drinking young adults. Twenty-two individuals were assigned to a three-week supplementation regimen with PhosphoLean™ or placebo. Impulsivity was assessed with self-report questionnaires and behavioral tasks pre- and post-supplementation. Although self-report measures of impulsivity did not change, supplementation with PhosphoLean™, but not placebo, significantly reduced false alarm rate on a Go/No-Go task. In addition, an association was found between improved sensitivity on the Go/No-Go task and reduced alcohol intake. These findings provide preliminary evidence that promoting fatty acid derived gut-brain dopamine communication may have therapeutic potential for reducing impulsivity in heavy drinkers.

  10. Assessing the Accuracy of Self-Reported Self-Talk

    Thomas M. Brinthaupt

    2015-05-01

    Full Text Available Self-Talk Scale (STS; Brinthaupt, Hein, & Kramer, 2009 is a self-report measure of self-talk frequency that has been shown to possess acceptable reliability and validity. However, no research using the STS has examined the accuracy of respondents’ self-reports. In the present paper, we report a series of studies directly examining the measurement of self-talk frequency and functions using the STS. The studies examine ways to validate self-reported self-talk by (1 comparing STS responses from 6 weeks earlier to recent experiences that might precipitate self-talk, (2 using experience sampling methods to determine whether STS scores are related to recent reports of self-talk over a period of a week, and (3 comparing self-reported STS scores to those provided by a significant other who rated the target on the STS. Results showed that (1 overall self-talk scores, particularly self-critical and self-reinforcing self-talk, were significantly related to reports of context-specific self-talk; (2 high STS scorers reported talking to themselves significantly more often during recent events compared to low STS scorers, and, contrary to expectations, (3 friends reported less agreement than strangers in their self-other self-talk ratings. Implications of the results for the validity of the STS and for measuring self-talk are presented.

    Full Text Available Abstract Background Psychological stress and negative mood have been related to increased vulnerability to influenza-like illness (ILI. This prospective study re-evaluated the predictive value of perceived stress for self-reported ILI. We additionally explored the role of the negative affectivity and social inhibition traits. Methods In this study, 5,404 respondents from the general population were assessed in terms of perceived stress, personality, and control variables (vaccination, vitamin use, exercise, etc.. ILI were registered weekly using self-report measures during a follow-up period of four weeks. Results Multivariable logistic regression analysis on ILI was performed to test the predictive power of stress and personality. In this model, negative affectivity (OR = 1.05, p = 0.009, social inhibition (OR = 0.97, p = 0.011, and perceived stress (OR = 1.03, p = 0.048 predicted ILI reporting. Having a history of asthma (OR = 2.33, p = Conclusion Elderly and socially inhibited persons tend to report less ILI as compared to their younger and less socially inhibited counterparts. In contrast, asthma, trait negative affectivity, and perceived stress were associated with higher self-report of ILI. Our results demonstrate the importance of including trait markers in future studies examining the relation between stress and self-report symptom measures.

  2. Impulse pumping modelling and simulation

    Pierre, B; Gudmundsson, J S

    2010-01-01

    Impulse pumping is a new pumping method based on propagation of pressure waves. Of particular interest is the application of impulse pumping to artificial lift situations, where fluid is transported from wellbore to wellhead using pressure waves generated at wellhead. The motor driven element of an impulse pumping apparatus is therefore located at wellhead and can be separated from the flowline. Thus operation and maintenance of an impulse pump are facilitated. The paper describes the different elements of an impulse pumping apparatus, reviews the physical principles and details the modelling of the novel pumping method. Results from numerical simulations of propagation of pressure waves in water-filled pipelines are then presented for illustrating impulse pumping physical principles, and validating the described modelling with experimental data.

  3. Improving Inhibitory Control Abilities (ImpulsE)-A Promising Approach to Treat Impulsive Eating?

    Preuss, Hanna; Pinnow, Marlies; Schnicker, Katja; Legenbauer, Tanja

    2017-11-01

    Although there is preliminary evidence that inhibitory control training improves impulsive eating, less is known about the effects on eating behaviour and weight loss in clinical samples. Sixty-nine treatment-seeking adults with obesity (binge-eating disorder 33.3%; other specific feeding and eating disorders 40.6%) were randomly blockwise allocated to ImpulsE, an intervention to improve inhibitory control and emotion regulation abilities or a guideline-appropriate cognitive behavioural therapy (CBT)-based treatment as usual. Self-reported and performance-based impulsivity, eating disorder pathology and BMI were compared at baseline (T1), post-treatment (T2) and 1- or 3-month follow-up. ImpulsE led to better food-specific inhibition performance (p = .004), but groups did not differ regarding improvements in global Eating Disorder Examination Questionnaire (EDE-Q) score at T2. At 3-month follow-up, binge eaters benefited most from ImpulsE (p = .028) and completers of ImpulsE demonstrated a significantly greater weight reduction (p = .030). The current findings propose ImpulsE as a promising approach to treat obesity, illustrating acceptability and additional benefits for course of weight.

  4. A negative relationship between ventral striatal loss anticipation response and impulsivity in borderline personality disorder.

    Herbort, Maike C; Soch, Joram; Wüstenberg, Torsten; Krauel, Kerstin; Pujara, Maia; Koenigs, Michael; Gallinat, Jürgen; Walter, Henrik; Roepke, Stefan; Schott, Björn H

    2016-01-01

    Patients with borderline personality disorder (BPD) frequently exhibit impulsive behavior, and self-reported impulsivity is typically higher in BPD patients when compared to healthy controls. Previous functional neuroimaging studies have suggested a link between impulsivity, the ventral striatal response to reward anticipation, and prediction errors. Here we investigated the striatal neural response to monetary gain and loss anticipation and their relationship with impulsivity in 21 female BPD patients and 23 age-matched female healthy controls using functional magnetic resonance imaging (fMRI). Participants performed a delayed monetary incentive task in which three categories of objects predicted a potential gain, loss, or neutral outcome. Impulsivity was assessed using the Barratt Impulsiveness Scale (BIS-11). Compared to healthy controls, BPD patients exhibited significantly reduced fMRI responses of the ventral striatum/nucleus accumbens (VS/NAcc) to both reward-predicting and loss-predicting cues. BIS-11 scores showed a significant positive correlation with the VS/NAcc reward anticipation responses in healthy controls, and this correlation, while also nominally positive, failed to reach significance in BPD patients. BPD patients, on the other hand, exhibited a significantly negative correlation between ventral striatal loss anticipation responses and BIS-11 scores, whereas this correlation was significantly positive in healthy controls. Our results suggest that patients with BPD show attenuated anticipation responses in the VS/NAcc and, furthermore, that higher impulsivity in BPD patients might be related to impaired prediction of aversive outcomes.

  5. Personality correlates of caffeine dependence: the role of sensation seeking, impulsivity, and risk taking.

    Jones, Heather A; Lejuez, C W

    2005-08-01

    The consumption of caffeine has become a growing concern, partially because of the withdrawal properties of the drug. The current study examined personality correlates of caffeine consumption and dependence in 60 university students. Self-report and behavioral measures of sensation seeking, impulsivity, and risk taking were administered to 2 groups, identified as caffeine dependent-high consuming or caffeine nondependent-low consuming. Scores on self-report measures of sensation seeking and impulsivity were related to group status, and only sensation seeking evidenced a significant relationship with group status when both variables were considered in a regression analysis. Implications of these findings and future directions are discussed. ((c) 2005 APA, all rights reserved).

  6. A Triadic Reflective-Impulsive-Interoceptive Awareness Model of General and Impulsive Information System Use: Behavioral Tests of Neuro-Cognitive Theory.

    Turel, Ofir; Bechara, Antoine

    2016-01-01

    This study examines a behavioral tripartite model developed in the field of addiction, and applies it here to understanding general and impulsive information technology use. It suggests that technology use is driven by two information-processing brain systems: reflective and impulsive, and that their effects on use are modulated by interoceptive awareness processes. The resultant reflective-impulsive-interoceptive awareness model is tested in two behavioral studies. Both studies employ SEM techniques to time-lagged self-report data from n 1 = 300 and n 2 = 369 social networking site users. Study 1 demonstrated that temptations augment the effect of habit on technology use, and reduce the effect of satisfaction on use. Study 2 showed that temptations strengthen the effect of habit on impulsive technology use, and weaken the effect of behavioral expectations on impulsive technology use. Hence, the results consistently support the notion that information technology users' behaviors are influenced by reflective and impulsive information processing systems; and that the equilibrium of these systems is determined, at least in part, by one's temptations. These results can serve as a basis for understanding the etiology of modern day addictions.

    2013-01-01

    The aims were to analyze whether the levels of self-reported bruxism and anxiety associate among otherwise healthy subjects, and to investigate the independent effects of anxiety and stress experience on the probability of self-reported bruxism. As part of a study on irregular shift work, a questionnaire was mailed to all employees of the Finnish Broadcasting Company with irregular shift work (number of subjects: n=750) and to an equal number of randomly selected employees in the same company with regular eight-hour daytime work. The response rates were 82.3% (56.6 % men) and 34.3 % (46.7 % men), respectively. Among the 874 respondents, those aware of more frequent bruxism reported significantly more severe anxiety (pbruxism and psychological states such as anxiety or stress may be related in working age subjects.

  8. Self-reported delinquency in a probation service in Brazil

    Lylla Cysne Frota D'Abreu

    2012-02-01

    Full Text Available International research shows that self-reported delinquency is a successful strategy to improve data collection on the identification of the so-called "dark figure", ie, offenses that are not reported to the justice system. This technique, however, is still little used in Brazil. Through documentary research from data archive, this study described the socio-demographic variables and the severity of unofficial delinquency of a sample of 211 adolescents who attended a probation service in Brazil. The results showed that adolescents in conflict with the law have delinquent engagement with higher polymorphism and intensity than the official data are able to identify. Self-reported delinquency can improve data collection, provide more reliable rates and guide more assertive intervention actions in these services.

  11. Self-Reported bruxism and associated factors in Israeli adolescents.

    Emodi Perlman, A; Lobbezoo, F; Zar, A; Friedman Rubin, P; van Selms, M K A; Winocur, E

    2016-06-01

    Little is known about the epidemiological characteristics of sleep and awake bruxism (SB and AB) in adolescents. The aims of the study were: to assess the prevalence rates of self-reported SB and AB in Israeli adolescents; to determine the associations between SB/AB and several demographical, exogenous and psychosocial factors in Israeli adolescents; and to investigate the possible concordance between SB and AB. The study made use of a questionnaire. The study population included 1000 students from different high schools in the centre of Israel. Prevalence of self-reported SB and AB in the Israeli adolescents studied was 9·2% and 19·2%, respectively. No gender difference was found regarding the prevalence of SB and AB. Multiple variable regression analysis revealed that the following predicting variables were related to SB: temporomandibular joint sounds (P = 0·002) and feeling stressed (P = 0·001). The following predicting variables were related to AB: age (P = 0·018), temporomandibular joint sounds (P = 0·002), oro-facial pain (P = 0·006), and feeling stressed (P = 0·002) or sad (P = 0·006). A significant association was found between SB and AB; that is, an individual reporting SB had a higher probability of reporting AB compared with an individual who did not report SB (odds ratio = 5·099). Chewing gum was the most common parafunction reported by adolescents. The results of this study demonstrate that self-reports of AB and SB are common in the Israeli adolescents population studied and are not related to gender. The significant correlation found between SB and AB may be a confounding bias that affects proper diagnosis of bruxism through self-reported questionnaires only. © 2016 John Wiley & Sons Ltd.

  12. Tai chi training reduces self-report of inattention in healthy young adults

    Alexander K. Converse

    2014-01-01

    Full Text Available It is important to identify effective non-pharmacological alternatives to stimulant medications that reduce symptoms of attention deficit hyperactivity disorder (ADHD. In this study of healthy young adults, we measured the effects of training in tai chi, which involves mindful attention to the body during movement. Using a non-randomized, controlled, parallel design, students in a 15-week introductory tai chi course (n=28 and control participants (n=44 were tested for ADHD indicators and cognitive function at three points over the course of the 15 weeks. The tai chi students' self-report of attention, but not hyperactivity-impulsivity, improved compared to controls. At baseline, inattention correlated positively with reaction time variability in an affective go/no-go task across all participants, and improvements in attention correlated with reductions in reaction time variability across the tai chi students. Affective bias changed in the tai chi students, as reaction times to positive- and negative-valenced words equalized over time. These results converge to suggest that tai chi training may help improve attention in healthy young adults. Further studies are needed to confirm these results and to evaluate tai chi as therapy for individuals with ADHD.

  13. Text mining a self-report back-translation.

    Blanch, Angel; Aluja, Anton

    2016-06-01

    There are several recommendations about the routine to undertake when back translating self-report instruments in cross-cultural research. However, text mining methods have been generally ignored within this field. This work describes a text mining innovative application useful to adapt a personality questionnaire to 12 different languages. The method is divided in 3 different stages, a descriptive analysis of the available back-translated instrument versions, a dissimilarity assessment between the source language instrument and the 12 back-translations, and an item assessment of item meaning equivalence. The suggested method contributes to improve the back-translation process of self-report instruments for cross-cultural research in 2 significant intertwined ways. First, it defines a systematic approach to the back translation issue, allowing for a more orderly and informed evaluation concerning the equivalence of different versions of the same instrument in different languages. Second, it provides more accurate instrument back-translations, which has direct implications for the reliability and validity of the instrument's test scores when used in different cultures/languages. In addition, this procedure can be extended to the back-translation of self-reports measuring psychological constructs in clinical assessment. Future research works could refine the suggested methodology and use additional available text mining tools. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  14. A Self-report of reading disabilities for adults: ATLAS

    Almudena Giménez

    2015-01-01

    Full Text Available In this paper a self-report questionnaire on reading-writing difficulties for adults in Spanish (ATLAS is presented. Studies that use self-report questionnaires as a tool for screening of reading-writing difficulties in adults were reviewed. Two studies were carried out to determine the validity and reliability of ATLAS. The first study was aimed to select the critical items and to assess their reliability and their ability to discriminate. In the second study the assessment reported through the answers to the questionnaire was contrasted with the results of psychometric tests. Results showed that (a items were suitable descriptors for adult difficulties, (b there were significant correlations between self-report scores and reading measures, and (c the items discriminate between good and poor readers. The results of this study demonstrated that ATLAS is a sensitive tool to screen adults with reading difficulties. As a further advantage, ATLAS is an easy-to-use and time-saving instrument.

  15. Readability and comprehension of self-report binge eating measures.

    Richards, Lauren K; McHugh, R Kathryn; Pratt, Elizabeth M; Thompson-Brenner, Heather

    2013-04-01

    The validity of self-report binge eating instruments among individuals with limited literacy is uncertain. This study aims to evaluate reading grade level and multiple domains of comprehension of 13 commonly used self-report assessments of binge eating for use in low-literacy populations. We evaluated self-report binge eating measures with respect to reading grade levels, measure length, formatting and linguistic problems. All measures were written at a reading grade level higher than is recommended for patient materials (above the 5th to 6th grade level), and contained several challenging elements related to comprehension. Correlational analyses suggested that readability and comprehension elements were distinct contributors to measure difficulty. Individuals with binge eating who have low levels of educational attainment or limited literacy are often underrepresented in measure validation studies. Validity of measures and accurate assessment of symptoms depend on an individual's ability to read and comprehend instructions and items, and these may be compromised in populations with lower levels of literacy.

  16. [Kleptomania: an irresistible impulse].

    Hatzigeorgiou, K

    2011-01-01

    This review presents the historical-epidemiological and clinical aspects of Kleptomania. The diagnostic criteria, on the basis of which it is categorized in the group of Impulse Control Disorders, are defined precisely. All the aspects of its causative pathogenesis are deeply analyzed, as they are projected through its phenomenological, psychoanalytical and psycho-biological approach. Particular emphasis is given on its differential diagnosis from other psycho-pathological conditions and especially from the co-morbidities that often accompany it. The frame of treatment is established and its course and the final outcome are analyzed. Finally, it is determined what should be the objectives of future research, which will contribute decisively to the ascertainment of the exact incidence of Kleptomania in the general population, to the clarification of its causative pathogenesis and especially to the most effective treatment of this serious mental disorder.

  17. Sleep-Wake State Tradeoffs, Impulsivity and Life History Theory

    Alissa A. Miller

    2012-04-01

    Full Text Available Evolutionary ecological theory predicts that sleep-wake state tradeoffs may be related to local environmental conditions and should therefore correlate to alterations in behavioral life history strategies. It was predicted that firefighters who slept more and reported better quality sleep on average would exhibit lower impulsivity inclinations related to slower life history trajectories. UPPS impulsivity scores and self-reported sleep averages were analyzed and indicated a negative association between sleep variables and urgency and a positive association with premeditation. Perseverance, and in some cases premeditation, however, disclosed an unpredicted marginally significant positive association between increased and emergency nighttime waking-related sleep deprivation. Sensation seeking was not associated with sleep variables, but was strongly associated with number of biological children. This research contributes to understanding the implications of human sleep across ecological and behavioral contexts and implies further research is necessary for constructing evolutionarily oriented measures of impulsivity inclination and its meaning in the context of life history strategies.

    This study was designed to evaluate the usage patterns of portable listening device (PLD) listeners, and the relationships between self-report measures and long-term dosimetry measures of listening habits. This study used a descriptive correlational design. Participants (N = 52) were 18-29 year old men and women who completed surveys. A randomly assigned subset (N = 24) of participants had their listening monitored by dosimetry for one week. Median weekly noise doses reported and measured through dosimetry were low (9-93%), but 14.3% of participants reported exceeding a 100% noise dose weekly. When measured by dosimetry, 16.7% of participants exceeded a 100% noise dose weekly. The self-report question that best predicted the dosimetry-measured dose asked participants to report listening duration and usual listening level on a visual-analog scale. This study reports a novel dosimetry system that can provide accurate measures of PLD use over time. When not feasible, though, the self-report question described could provide a useful research or clinical tool to estimate exposure from PLD use. Among the participants in this study, a small but substantial percentage of PLD users incurred exposure from PLD use alone that increases their risk of music-induced hearing loss.

    This study examined clinical characteristics and laboratory-measured impulsive behavior of adolescents engaging in either non-suicidal self-injury with (NSSI+SA; n=25) or without (NSSI-Only; n=31) suicide attempts. We hypothesized that adolescent with NSSI+SI would exhibit more severe clinical symptoms and higher levels of behavioral impulsivity compared to adolescents with NSSI-Only. Adolescents were recruited from an inpatient psychiatric hospital unit and the two groups were compared on demographic characteristics, psychopathology, self-reported clinical ratings, methods of non-suicidal self-injury, and two laboratory impulsivity measures. Primary evaluations were conducted during psychiatric hospitalization, and a subset of those tested during hospitalization was retested 4-6 weeks after discharge. During hospitalization, NSSI+SA patients reported worse depression, hopelessness, and impulsivity on standard clinical measures, and demonstrated elevated impulsivity on a reward-directed laboratory measure compared to NSSI-Only patients. In the follow-up analyses, depression, hopelessness, suicidal ideation, and laboratory impulsivity were improved for both groups, but the NSSI+SA group still exhibited significantly more depressive symptoms, hopelessness, and impulsivity than the NSSI-Only group. Risk assessments for adolescents with NSSI+SA should include consideration not only of the severity of clinical symptoms but of the current level impulsivity as well.

  20. Suicidality in Bipolar Disorder: The Role of Emotion-Triggered Impulsivity.

    Johnson, Sheri L; Carver, Charles S; Tharp, Jordan A

    2017-04-01

    A growing body of research suggests that impulsive responses to emotion more robustly predict suicidality than do other forms of impulsivity. This issue has not yet been examined within bipolar disorder, however. Participants diagnosed with bipolar I disorder (n = 133) and control participants (n = 110) diagnosed with no mood or psychotic disorder completed self-report measures of emotion-triggered impulsivity (Negative and Positive Urgency Scales) and interviews concerning lifetime suicidality. Analyses examined the effects of emotion-triggered impulsivity alone and in combination with gender, age of onset, depression severity, comorbid anxiety, comorbid substance use, and medication. A history of suicide ideation and attempts, as well as self-harm, were significantly more common in the bipolar disorder group compared with the control group. Impulsive responses to positive emotions related to suicide ideation, attempts, and self-harm within the bipolar group. Findings extend research on the importance of emotion-triggered impulsivity to a broad range of key outcomes within bipolar disorder. The discussion focuses on limitations and potential clinical implications. © 2016 The American Association of Suicidology.

  1. Poor Sleep and Its Relation to Impulsivity in Patients with Antisocial or Borderline Personality Disorders.

    Van Veen, M M; Karsten, J; Lancel, M

    2017-01-01

    Studies investigating sleep and personality disorders consistently demonstrate a relation between personality disorders characterized by behavioral disinhibition and/or emotional dysregulation (traditionally termed cluster B personality disorders) and poor sleep. This finding is in line with previous studies associating insomnia with impulsive behavior, since this is a core characteristic of both antisocial and borderline personality disorder. The current study investigates a group (n = 112) of forensic psychiatric inpatients with antisocial or borderline personality disorder or traits thereof. Subjective sleep characteristics and impulsivity were assessed with the Pittsburgh Sleep Quality Index, the Sleep Diagnosis List, and the Barratt Impulsiveness Scale, respectively. More than half of the patients (53.6%) report poor sleep quality and 22.3% appears to suffer from severe chronic insomnia. Both poor sleep quality and chronic insomnia are significantly associated with self-reported impulsivity, in particular with attentional impulsiveness. This association was not significantly influenced by comorbid disorders. Actively treating sleep problems in these patients may not only improve sleep quality, mental health, and physical well-being, but may also have impact on impulsivity-related health risks by increasing self-control.

  2. Self-reported cognitive inconsistency in older adults.

    Vanderhill, Susan; Hultsch, David F; Hunter, Michael A; Strauss, Esther

    2010-01-01

    Insight into one's own cognitive abilities, or metacognition, has been widely studied in developmental psychology. Relevance to the clinician is high, as memory complaints in older adults show an association with impending dementia, even after controlling for likely confounds. Another candidate marker of impending dementia under study is inconsistency in cognitive performance over short time intervals. Although there has been a recent proliferation of studies of cognitive inconsistency in older adults, to date, no one has examined adults' self-perceptions of cognitive inconsistency. Ninety-four community-dwelling older adults (aged 70-91) were randomly selected from a parent longitudinal study of short-term inconsistency and long-term cognitive change in aging. Participants completed a novel 40-item self-report measure of everyday cognitive inconsistency, including parallel scales indexing perceived inconsistency 5 years ago and at present, yielding measures of past, present, and 5-year change in inconsistency. The questionnaire showed acceptable psychometric characteristics. The sample reported an increase in perceived inconsistency over time. Higher reported present inconsistency and greater 5-year increase in inconsistency were associated with noncognitive (e.g., older age, poorer ADLs, poorer health, higher depression), metacognitive (e.g., poorer self-rated memory) and neuropsychological (e.g., poorer performance and greater 5-year decline in global cognitive status, vocabulary, and memory) measures. Correlations between self-reported inconsistency and neuropsychological performance were attenuated, but largely persisted when self-rated memory and age were controlled. Observed relationships between self-reported inconsistency and measures of neuropsychological (including memory) status and decline suggest that self-perceived inconsistency may be an area of relevance in evaluating older adults for memory disorders.

  3. Validity of self-reported adult secondhand smoke exposure.

    2015-01-01

    Exposure of adults to secondhand smoke (SHS) has immediate adverse effects on the cardiovascular system and causes coronary heart disease. The current study evaluated brief self-report screening measures for accurately identifying adult cardiology patients with clinically significant levels of SHS exposure in need of intervention. A cross-sectional study conducted in a university-affiliated cardiology clinic and cardiology inpatient service. Participants were 118 non-smoking patients (59% male, mean age=63.6 years, SD=16.8) seeking cardiology services. Serum cotinine levels and self-reported SHS exposure in the past 24 h and 7 days on 13 adult secondhand exposure to smoke (ASHES) items. A single item assessment of SHS exposure in one's own home in the past 7 days was significantly correlated with serum cotinine levels (r=0.41, p85% and correct classification rates >85% at cotinine cut-off points of >0.215 and >0.80 ng/mL. The item outperformed multi-item scales, an assessment of home smoking rules, and SHS exposure assessed in other residential areas, automobiles and public settings. The sample was less accurate at self-reporting lower levels of SHS exposure (cotinine 0.05-0.215 ng/mL). The single item ASHES-7d Home screener is brief, assesses recent SHS exposure over a week's time, and yielded the optimal balance of sensitivity and specificity. The current findings support use of the ASHES-7d Home screener to detect SHS exposure and can be easily incorporated into assessment of other major vital signs in cardiology.

  4. Self-reported Medication Adherence and CKD Progression

    Esteban A. Cedillo-Couvert

    2018-05-01

    Full Text Available Introduction: In the general population, medication nonadherence contributes to poorer outcomes. However, little is known about medication adherence among adults with chronic kidney disease (CKD. We evaluated the association of self-reported medication adherence with CKD progression and all-cause death in patients with CKD. Methods: In this prospective observational study of 3305 adults with mild-to-moderate CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC Study, the baseline self-reported medication adherence was assessed by responses to 3 questions and categorized as high, medium, and low. CKD progression (50% decline in eGFR or incident end-stage renal disease and all-cause death were measured using multivariable Cox proportional hazards. Results: Of the patients, 68% were categorized as high adherence, 17% medium adherence, and 15% low adherence. Over a median follow-up of 6 years, there were 969 CKD progression events and 675 deaths. Compared with the high-adherence group, the low-adherence group experienced increased risk for CKD progression (hazard ratio = 1.27, 95% confidence interval = 1.05, 1.54 after adjustment for sociodemographic and clinical factors, cardiovascular medications, number of medication types, and depressive symptoms. A similar association existed between low adherence and all-cause death, but did not reach standard statistical significance (hazard ratio = 1.14 95% confidence interval = 0.88, 1.47. Conclusion: Baseline self-reported low medication adherence was associated with an increased risk for CKD progression. Future work is needed to better understand the mechanisms underlying this association and to develop interventions to improve adherence. Keywords: CKD, death, medication adherence, progression

    To evaluate the validity of widely used questionnaire items on work schedule using objective registry data as reference. A cohort study of hospital employees who responded to a self-administered questionnaire on work schedule in 2008, 2012 and 2014 and were linked to individual-level pay-roll-based records on work shifts. For predictive validity, leisure-time fatigue was assessed. According to the survey data in 2014 (n=8896), 55% of the day workers had at least 1 year of earlier shift work experience. 8% of the night shift workers changed to day work during the follow-up. Using pay-roll data as reference, questions on 'shift work with night shifts' and 'permanent night work' showed high sensitivity (96% and 90%) and specificity (92% and 97%). Self-reported 'regular day work' showed moderate sensitivity (73%), but high specificity (99%) and 'shift work without night shifts' showed low sensitivity (62%) and moderate specificity (87%). In multivariate logistic regression analysis, the age-adjusted, sex-adjusted and baseline fatigue-adjusted association between 'shift work without night shifts' and leisure-time fatigue was lower for self-reported compared with objective assessment (1.30, 95% CI 0.94 to 1.82, n=1707 vs 1.89, 95% CI 1.06 to 3.39, n=1627). In contrast, shift work with night shifts, compared with permanent day work, was similarly associated with fatigue in the two assessments (2.04, 95% CI 1.62 to 2.57, n=2311 vs 1.82, 95% CI 1.28 to 2.58, n=1804). The validity of self-reported assessment of shift work varies between work schedules. Exposure misclassification in self-reported data may contribute to bias towards the null in shift work without night shifts. Published by the BMJ Publishing Group Limited.

  6. Mobile technology habits: patterns of association among device usage, intertemporal preference, impulse control, and reward sensitivity.

    Wilmer, Henry H; Chein, Jason M

    2016-10-01

    Mobile electronic devices are playing an increasingly pervasive role in our daily activities. Yet, there has been very little empirical research investigating how mobile technology habits might relate to individual differences in cognition and affect. The research presented in this paper provides evidence that heavier investment in mobile devices is correlated with a relatively weaker tendency to delay gratification (as measured by a delay discounting task) and a greater inclination toward impulsive behavior (i.e., weaker impulse control, assessed behaviorally and through self-report) but is not related to individual differences in sensitivity to reward. Analyses further demonstrated that individual variation in impulse control mediates the relationship between mobile technology usage and delay of gratification. Although based on correlational results, these findings lend some backing to concerns that increased use of portable electronic devices could have negative impacts on impulse control and the ability to appropriately valuate delayed rewards.

    1988-03-15

    Using a femtosecond dye laser, we observe in real-time vibrational oscillations excited by impulsive stimulated Raman scattering (ISRS) close to an electronic resonance. We perform single-beam Raman excitation and probe the driven coherence by a polarization-sensitive detection. We demonstrate for the first time impulsively Raman-induced dichroism, birefringence as well as frequency and time delay shifts. We analyse the characteristics of resonant ISRS on a vibrational mode of a dye molecule (malachite green) in solution.

  9. Self-Reported Health Among Recently Incarcerated Mothers.

    Turney, Kristin; Wildeman, Christopher

    2015-10-01

    We examined self-reported health among formerly incarcerated mothers. We used data from the Fragile Families and Child Wellbeing Study (n = 4096), a longitudinal survey of mostly unmarried parents in urban areas, to estimate the association between recent incarceration (measured as any incarceration in the past 4 years) and 5 self-reported health conditions (depression, illicit drug use, heavy drinking, fair or poor health, and health limitations), net of covariates including health before incarceration. In adjusted logistic regression models, recently incarcerated mothers, compared with their counterparts, have an increased likelihood of depression (odds ratio [OR] = 1.60; 95% confidence interval [CI] = 1.18, 2.17), heavy drinking (OR = 1.79; 95% CI = 1.19, 2.68), fair or poor health (OR = 1.49; 95% CI = 1.08, 2.06), and health limitations (OR = 1.78; 95% CI = 1.27, 2.50). This association is similar across racial/ethnic subgroups and is larger among mothers who share children with fathers who have not been recently incarcerated. Recently incarcerated mothers struggle with even more health conditions than expected given the disadvantages they experience before incarceration. Furthermore, because incarceration is concentrated among those who are most disadvantaged, incarceration may increase inequalities in population health.

    The present study aimed to identify factors associated with self-reported acute and chronic voice disorders among municipal elementary school teachers in the city of Montes Claros, in the State of Minas Gerais, Brazil. The dependent variable, self-reported dysphonia, was determined via a single question, "Have you noticed changes in your voice quality?" and if so, a follow-up question queried the duration of this change, acute or chronic. The independent variables were dichotomized and divided into five categories: sociodemographic and economic data; lifestyle; organizational and environmental data; health-disease processes; and voice. Analyses of associated factors were performed via a hierarchical multiple logistic regression model. The present study included 226 teachers, of whom 38.9% reported no voice disorders, 35.4% reported an acute disorder, and 25.7% reported a chronic disorder. Excessive voice use daily, consuming more than one alcoholic drink per time, and seeking medical treatment because of voice disorders were associated factors for acute and chronic voice disorders. Consuming up to three glasses of water per day was associated with acute voice disorders. Among teachers who reported chronic voice disorders, teaching for over 15 years and the perception of disturbing or unbearable noise outside the school were both associated factors. Identification of organizational, environmental, and predisposing risk factors for voice disorders is critical, and furthermore, a vocal health promotion program may address these issues.

  11. Smartphone addiction, daily interruptions and self-reported productivity

    Full Text Available The advent of the smartphone has dramatically altered how we communicate, navigate, work and entertain ourselves. While the advantages of this new technology are clear, constant use may also bring negative consequences, such as a loss of productivity due to interruptions in work life. A link between smartphone overuse and loss of productivity has often been hypothesized, but empirical evidence on this question is scarce. The present study addressed this question by collecting self-report data from N=262 participants, assessing private and work-related smartphone use, smartphone addiction and self-rated productivity. Our results indicate a moderate relationship between smartphone addiction and a self-reported decrease in productivity due to spending time on the smartphone during work, as well as with the number of work hours lost to smartphone use. Smartphone addiction was also related to a greater amount of leisure time spent on the smartphone and was strongly related to a negative impact of smartphone use on daily non-work related activities. These data support the idea that tendencies towards smartphone addiction and overt checking of the smartphone could result in less productivity both in the workplace and at home. Results are discussed in relation to productivity and technostress.

    Full Text Available Self-reported disability in performing daily life activities was assessed in adults with severe obesity (BMI ≥ 35 kg/m2 using the Health Assessment Questionnaire (HAQ. 262 participants were recruited into three BMI groups: Group I: 35–39.99 kg/m2; Group II: 40–44.99 kg/m2; Group III: ≥45.0 kg/m2. Progressively increasing HAQ scores were documented with higher BMI; Group I HAQ score: 0.125 (median (range: 0–1.75; Group II HAQ score: 0.375 (0–2.5; Group III HAQ score: 0.75 (0–2.65 (Group III versus II P 0. The prevalence of this degree of disability increased with increasing BMI and age. It also correlated to type 2 diabetes, metabolic syndrome, and clinical depression, but not to gender. Our data suggest that severe obesity is associated with self-reported disability in performing common daily life activities, with increasing degree of disability as BMI increases over 35 kg/m2. Functional assessment is crucial in obesity management, and establishing the disability profiles of obese patients is integral to both meet the specific healthcare needs of individuals and develop evidence-based public health programs, interventions, and priorities.

  17. Individual Differences in Cognitive Control Circuit Anatomy Link Sensation Seeking, Impulsivity, and Substance Use

    Hollinshead, Marisa O.; Roffman, Joshua L.; Smoller, Jordan W.; Buckner, Randy L.

    2016-01-01

    Individuals vary widely in their tendency to seek stimulation and act impulsively, early developing traits with genetic origins. Failures to regulate these behaviors increase risk for maladaptive outcomes including substance abuse. Here, we explored the neuroanatomical correlates of sensation seeking and impulsivity in healthy young adults. Our analyses revealed links between sensation seeking and reduced cortical thickness that were preferentially localized to regions implicated in cognitive control, including anterior cingulate and middle frontal gyrus (n = 1015). These associations generalized to self-reported motor impulsivity, replicated in an independent group (n = 219), and correlated with heightened alcohol, tobacco, and caffeine use. Critically, the relations between sensation seeking and brain structure were evident in participants without a history of alcohol or tobacco use, suggesting that observed associations with anatomy are not solely a consequence of substance use. These results demonstrate that individual differences in the tendency to seek stimulation, act on impulse, and engage in substance use are correlated with the anatomical structure of cognitive control circuitry. Our findings suggest that, in healthy populations, covariation across these complex multidimensional behaviors may in part originate from a common underlying biology. SIGNIFICANCE STATEMENT Impaired cognitive control may result in a tendency to seek stimulation impulsively and an increased risk for maladaptive outcomes, including substance abuse. Here, we examined the structural correlates of sensation seeking and impulsivity in a large cohort of healthy young adults. Our analyses revealed links between sensation seeking and reduced cortical thickness that were preferentially localized to regions implicated in cognitive control, including anterior cingulate and middle frontal gyrus. The observed associations generalized to motor impulsivity, replicated in an independent group

  18. How do impulsivity and education relate to smoking initiation and cessation among young adults?

    Kvaavik, Elisabeth; Rise, Jostein

    2012-09-01

    This study examined the predictive value of impulsivity for starting and quitting smoking and whether education had an independent effect on smoking careers or moderated the impulsivity-smoking association. Two waves of the cohort study Young in Norway were used in the present study (third wave: 1999, age range: 19-32 years; fourth wave: 2005, age range: 25-38 years). Postal questionnaires were used for data collection. Subjects participating in 1999 and 2005 were eligible (N = 2,562). Stable smokers (daily smokers in 1999 and 2005) and nonsmokers (never smokers in 1999 and 2005), quitters (daily smokers in 1999, nonsmokers in 2005), and starters (never smokers in 1999, daily smokers in 2005) constituted the analytical sample (1,776 men and women). The associations between self-reported impulsivity and education and smoking were investigated using logistic regression analyses. The odds ratio (OR) for a 1-unit increase in the impulsivity score was 2.16 (95% CI [1.09, 4.30]) for smoking initiation, whereas the OR [95% CI] for low compared with high education was 2.55 (95% CI [1.36, 4.77]). Education, but not impulsivity, emerged as a significant determinant for smoking cessation compared with continued smoking. The OR for quitting smoking by low compared with high education was 0.61 (95% CI [0.42, 0.90]). Mutual adjustment for education and impulsivity did not change any of the results. The interaction term between impulsivity and education was not significantly related to smoking. Because impulsivity emerged as important for smoking initiation regardless of educational level, it should be considered when planning and implementing smoking prevention programs for both low and high socioeconomic groups.

  19. Prospective Evaluation of Self-Reported Aggression in Transgender Persons.

    Although research on the relation between testosterone and aggression in humans is inconclusive, guidelines (including the World Professional Association for Transgender Health Standards of Care, edition 7) have warned for an increase in aggression in transgender men taking testosterone treatment. To investigate the association between levels of testosterone and aggression in treatment-seeking transgender people and explore the role of mental health psychopathology (anxiety and depressive symptoms) and social support in aggression in this population. Every transgender person invited for assessment at a national transgender health clinic in the United Kingdom during a 3-year period (2012-2015) completed self-report measures for interpersonal problems, including levels of aggression (Inventory of Interpersonal Problems [IIP-32]), symptoms of anxiety and depression (Hospital Anxiety and Depression Scale [HADS]), social support (Multidimensional Scale of Perceived Social Support), and experiences of transphobia before and 1 year after the initiation of gender-affirming hormonal therapy. Correlations between prospective scores for the IIP-32 factor "too aggressive" and prospective levels of sex steroids, prospective psychological (HADS), and baseline psychosocial measurements were tested. Prospective scores for the factor "too aggressive" were not correlated to prospective serum testosterone levels. Results of 140 people (56 transgender men, 84 transgender women) were analyzed. A prospective increase in scores for the factor "too aggressive" of the IIP-32 in transgender men 1 year after being treated with testosterone treatment or a decrease of the IIP-32 aggression scores in transgender women 1 year after gender-affirming hormonal therapy was not found. However, a positive correlation was found between increasing HADS anxiety scores and increasing scores for the IIP-32 "too aggressive" score in the entire study population and a positive correlation with lower support

  1. Identifying high-functioning dyslexics: is self-report of early reading problems enough?

    Deacon, S Hélène; Cook, Kathryn; Parrila, Rauno

    2012-07-01

    We used a questionnaire to identify university students with self-reported difficulties in reading acquisition during elementary school (self-report; n=31). The performance of the self-report group on standardized measures of word and non-word reading and fluency, passage comprehension and reading rate, and phonological awareness was compared to that of two other groups of university students: one with a recent diagnosis (diagnosed; n=20) and one with no self-reported reading acquisition problems (comparison group; n=33). The comparison group outperformed both groups with a history of reading difficulties (self-report and diagnosed) on almost all measures. The self-report and diagnosed groups performed similarly on most tasks, with the exception of untimed reading comprehension (better performance for diagnosed) and reading rate (better performance for self-report). The two recruitment methods likely sample from the same underlying population but identify individuals with different adaptive strategies.

    Schäfer, G; Smoltczyk, H; Dengler, W; Buchkremer, G

    2000-04-01

    The aim of this study was to estimate the frequency and nature of self-reported and drug-related emergencies. 47 patients of a ward for opiate detoxification were interviewed about their experiences with drug-related emergencies. Typical categories had to be found like overdoses, seizures, accidents and suicide attempts respectively. 68% had own experience with drug-related emergency. A majority suffered opiate overdose with different extensions as unconsciousness or breath-depression. Alcohol and polydrug use was associated with overdose. Drug-related accidents were only reported by men. Half the number of drug-related emergencies were treated in hospital. Most emergencies occurred alone either in a home environment or outside. Harm reduction interventions like observed user rooms should be established. Furthermore other strategies to reduce the number of emergencies as sharing naloxon or resuscitation programs in wards for detoxification could also be an effective method to prevent near fatal or fatal overdoses in dependent subjects.

    2014-12-01

    Full Text Available Many adult outpatients with ADHD report an oversensitivity to light. We explored the link between ADHD and photophobia in an online survey (N=494. Self-reported photophobia was prevalent in 69% of respondents with, and in 28% of respondents without, ADHD (symptoms. The ADHD (symptoms group wore sunglasses longer during daytime in all seasons. Photophobia may be related to the functioning of the eyes, which mediate dopamine and melatonin production systems in the eye. In the brain, dopamine and melatonin are involved in both ADHD and circadian rhythm disturbances. Possibly, the regulation of the dopamine and melatonin systems in the eyes and in the brain are related. Despite the study’s limitations, the results are encouraging for further study on the pathophysiology of ADHD, eye functioning, and circadian rhythm disturbances.

    Police officers have a higher risk for cardiovascular disease. Reductions in occupational physical activity may contribute to the risk, yet there have been few efforts to characterize the physical demands of police work beyond self-report. To compare measured physical activity between work and off-duty hours and assess the effects of stress on physical activity. Officers (n = 119) from six departments wore a pattern recognition monitor for 96 hours to measure total energy expenditure (kilocalorie per hour) (1k/cal = 4184 joules), activity intensity, and step count per hour. Participants were more active on their off-duty days than at work; the effects of stress on physical activity seemed moderated by sex. Police work is primarily a sedentary occupation, and officers tend to be more active on their off-duty days than during their work hours.

  8. Distribution and Correlates of Self-Reported Crimes of Trust

    Menard, Scott; Morris, Robert G.; Gerber, Jurg; Covey, Herbert C.

    2012-01-01

    This study examines the distribution and correlates of a special class of property crimes, crimes of trust, using longitudinal and cross sectional self-report data from a national sample. We begin by defining crimes of trust and consider their conceptual relationship to “conventional” property crimes, which we here characterize as crimes of stealth, and to white collar crimes, which are defined in terms of the social status of the perpetrators. Crimes of trust are here defined as property crimes that typically involve deliberate contact with the victim or, where there is more than one victim, with at least one or more victims, in which there is typically more of a focus on concealing the fact that a crime has been committed than on concealing the identity of the perpetrator (as is the case in crimes of stealth), without regard to the socioeconomic status of the perpetrator (thus including but not limited to white collar crimes). The focus here is on crimes of trust committed by individuals (as opposed to corporate crime). We first examine their distribution by sociodemographic characteristics, then examine the correlation of crimes of trust with other types of illegal behavior, using data from the National Youth Survey Family Study, including (1) longitudinal self-report data from a nationally representative panel of individuals who were 11–18 years old in 1976–77 and who were followed through early middle age (ages 36–44) in 2002–2003, plus (2) cross-sectional data on these individuals plus their parents, spouses, and children age 11 and older in 2002–2003 (total age range 11–88). The results suggest that crimes of trust have a different age-crime curve from conventional crimes, and that they are not as strongly correlated with problem substance use, gender, and other socioeconomic indicators as conventional crimes.

  9. Body awareness: construct and self-report measures.

    Wolf E Mehling

    Full Text Available Heightened body awareness can be adaptive and maladaptive. Improving body awareness has been suggested as an approach for treating patients with conditions such as chronic pain, obesity and post-traumatic stress disorder. We assessed the psychometric quality of selected self-report measures and examined their items for underlying definitions of the construct.PubMed, PsychINFO, HaPI, Embase, Digital Dissertations Database.Abstracts were screened; potentially relevant instruments were obtained and systematically reviewed. Instruments were excluded if they exclusively measured anxiety, covered emotions without related physical sensations, used observer ratings only, or were unobtainable. We restricted our study to the proprioceptive and interoceptive channels of body awareness. The psychometric properties of each scale were rated using a structured evaluation according to the method of McDowell. Following a working definition of the multi-dimensional construct, an inter-disciplinary team systematically examined the items of existing body awareness instruments, identified the dimensions queried and used an iterative qualitative process to refine the dimensions of the construct.From 1,825 abstracts, 39 instruments were screened. 12 were included for psychometric evaluation. Only two were rated as high standard for reliability, four for validity. Four domains of body awareness with 11 sub-domains emerged. Neither a single nor a compilation of several instruments covered all dimensions. Key domains that might potentially differentiate adaptive and maladaptive aspects of body awareness were missing in the reviewed instruments.Existing self-report instruments do not address important domains of the construct of body awareness, are unable to discern between adaptive and maladaptive aspects of body awareness, or exhibit other psychometric limitations. Restricting the construct to its proprio- and interoceptive channels, we explore the current understanding

  10. Self-reported hearing performance in workers exposed to solvents

    Adrian Fuente

    2013-02-01

    Full Text Available OBJECTIVE: To compare hearing performance relating to the peripheral and central auditory system between solvent-exposed and non-exposed workers. METHODS: Forty-eight workers exposed to a mixture of solvents and 48 non-exposed control subjects of matched age, gender and educational level were selected to participate in the study. The evaluation procedures included: pure-tone audiometry (500 - 8,000 Hz, to investigate the peripheral auditory system; the Random Gap Detection test, to assess the central auditory system; and the Amsterdam Inventory for Auditory Disability and Handicap, to investigate subjects' self-reported hearing performance in daily-life activities. A Student t test and analyses of covariance (ANCOVA were computed to determine possible significant differences between solvent-exposed and non-exposed subjects for the hearing level, Random Gap Detection test and Amsterdam Inventory for Auditory Disability and Handicap. Pearson correlations among the three measures were also calculated. RESULTS: Solvent-exposed subjects exhibited significantly poorer hearing thresholds for the right ear than non-exposed subjects. Also, solvent-exposed subjects exhibited poorer results for the Random Gap Detection test and self-reported poorer listening performance than non-exposed subjects. Results of the Amsterdam Inventory for Auditory Disability and Handicap were significantly correlated with the binaural average of subject pure-tone thresholds and Random Gap Detection test performance. CONCLUSIONS: Solvent exposure is associated with poorer hearing performance in daily life activities that relate to the function of the peripheral and central auditory system.

  11. Marijuana Use and Self-reported Quality of Eyesight.

    Akano, Obinna F

    2017-05-01

    There is increasing use of marijuana among young adults and more states in the United States are legalizing medical marijuana use. A number of studies have revealed both the beneficial and harmful effects of marijuana to the human system. Despite some beneficial effects, studies have shown marijuana to have a lot of deleterious effects on the visual system, which subsequently reduces the quality of eyesight. The aim of this study was to investigate if heavy marijuana smoking is associated with a poor quality of eyesight compared with light/no use of marijuana. The National Longitudinal Survey of Youths (NLSY79), a nationally representative sample of 12,686 young men and women surveyed in 1979 to 2010 was used for this study. The quality of eyesight of 1304 heavy marijuana users was compared with 1304 respondents with light or no marijuana use. The t test, multivariate and weighted logistic regression were used in the data analysis. There was no statistically significant difference in the self-reported quality of eyesight among heavy marijuana smokers compared with youths who never used marijuana or are light marijuana users. Among heavy marijuana smokers, males and high school graduates have decreased odds of reporting a poor quality of eyesight, whereas blacks have increased odds of reporting a poor quality of eyesight. The self-reported quality of eyesight among marijuana users can aid clinicians and other health practitioners facilitate the development of sex-, racial/ethnic-, and educational level-informed prevention and early intervention programs and also help characterize public opinions regarding cannabis, which are particularly relevant given the ongoing debate concerning the medicalization and legalization of cannabis in the United States.

  12. Online and live regular poker players: Do they differ in impulsive sensation seeking and gambling practice?

    Barrault, Servane; Varescon, Isabelle

    2016-01-01

    Background and aims Online gambling appears to have special features, such as anonymity, speed of play and permanent availability, which may contribute to the facilitation and increase in gambling practice, potentially leading to problem gambling. The aims of this study were to assess sociodemographic characteristics, gambling practice and impulsive sensation seeking among a population of regular poker players with different levels of gambling intensity and to compare online and live players. Methods 245 regular poker players (180 online players and 65 live players) completed online self-report scales assessing sociodemographic data, pathological gambling (SOGS), gambling practice (poker questionnaire) and impulsive sensation seeking (ImpSS). We used SOGS scores to rank players according to the intensity of their gambling practice (non-pathological gamblers, problem gamblers and pathological gamblers). Results All poker players displayed a particular sociodemographic profile: they were more likely to be young men, executives or students, mostly single and working full-time. Online players played significantly more often whereas live players reported significantly longer gambling sessions. Sensation seeking was high across all groups, whereas impulsivity significantly distinguished players according to the intensity of gambling. Discussion Our results show the specific profile of poker players. Both impulsivity and sensation seeking seem to be involved in pathological gambling, but playing different roles. Sensation seeking may determine interest in poker whereas impulsivity may be involved in pathological gambling development and maintenance. Conclusions This study opens up new research perspectives and insights into preventive and treatment actions for pathological poker players. PMID:28092187

    Impulsivity has mainly been described as a negative or dysfunctional characteristic associated with several disorders. However, impulsivity is not only related to dysfunctional outcomes and may explain individual differences in optimal human functioning as well. The Dickman Impulsivity Inventory (DII) is a self-report instrument measuring both the dysfunctional and the functional aspects of impulsivity. In this study, we performed the translation and cultural adaptation of the DII to the Brazilian context and analyzed its psychometric properties. Translation and cultural adaptation followed a rigorous process, which relied on an expert panel in the cross-cultural adaptation of psychological instruments. Data from 405 undergraduate students were obtained for the Brazilian version of the DII (Br-DII). The 23 items of the Br-DII was considered unsuitable according to model fit indices of the Confirmatory Factor Analysis (both for Oblique and Orthogonal models). Exploratory Factor Analysis showed an 18 items version of the Br-DII to be suitable (CFI = 0.92; TLI = 0.90, and RMSEA = 0.057). The DII's 18 items version also showed adequate Cronbach's alpha, intraclass correlation coefficient, and convergent and discriminant validity with the BIS-11. Therefore, the Br-DII demonstrated reliability and validity in the measurement of functional and dysfunctional impulsivity.

    2016-01-19

    Alcohol dependence (AD) and aggression-impulsivity are both associated with increased suicide risk. There is a need to evaluate clinical tools in order to improve suicide risk assessment of AD patients. The present study consisted of 95 individuals with a diagnosis of AD, consecutively admitted for addiction treatment, compared with 95 healthy controls. Suicidal risk was assessed together with exposure of violence and impulsivity. AD patients reported significantly higher rates of exposure to violence in childhood, as measured by the Karolinska Interpersonal Violence Scale (KIVS), compared to HC. Within the AD group, individuals with history of suicidal ideation and suicidal behavior reported higher levels of violence experience compared to AD individuals without such history. AD patients with previous suicidal ideation scored higher on self-reported impulsivity as assessed by the Barratt Impulsivity Scale (BIS). Our main finding was that experience of trauma and expression of violent behavior, coupled with increased impulsivity are associated with an elevated suicide risk in AD patients. Future longitudinal studies assessing these traits are needed to evaluate their potential role in identifying AD patients at risk of future suicide.

    Latent chronic infection with Toxoplasma gondii (T. gondii), a common neurotropic pathogen, has been previously linked with suicidal self-directed violence (SSDV). We sought to determine if latent infection with T. gondii is associated with trait aggression and impulsivity, intermediate phenotypes for suicidal behavior, in psychiatrically healthy adults. Traits of aggression and impulsivity were analyzed in relationship to IgG antibody seropositivity for T. gondii and two other latent neurotropic infections, herpes simplex virus 1 (HSV1) and cytomegalovirus (CMV). One thousand community-residing adults residing in the Munich metropolitan area with no Axis I or II conditions by SCID for DSM-IV (510 men, 490 women, mean age 53.6 ± 15.8, range 20-74). Plasma samples were tested for IgG antibodies to T. gondii, HSV-1 and CMV by ELISA. Self-reported ratings of trait aggression scores (Questionnaire for Measuring Factors of Aggression [FAF]) and trait impulsivity (Sensation-Seeking Scale-V [SSS-V]) were analyzed using linear multivariate methods. T. gondii IgG seropositivity was significantly associated with higher trait reactive aggression scores among women (p impulsive sensation-seeking (SSS-V Disinhibition) among younger men (p impulsivity, personality traits considered as endophenotypes for SSDV, are associated with latent T. gondii infection in a gender and age-specific manner, and could be further investigated as prognostic and treatment targets in T. gondii-positive individuals at risk for SSDV.

  16. Neuropsychological performance, impulsivity, ADHD symptoms, and novelty seeking in compulsive buying disorder.

    Black, Donald Wayne; Shaw, Martha; McCormick, Brett; Bayless, John David; Allen, Jeff

    2012-12-30

    We examined the neuropsychological performance of people with compulsive buying disorder (CBD) and control subjects, along with trait impulsivity, symptoms of attention deficit hyperactivity disorder (ADHD), and selected personality characteristics. Subjects received a comprehensive neuropsychological test battery, depression and ADHD symptom assessment, the Barratt Impulsiveness Scale, and a version of the Temperament and Character Inventory. Persons with CBD (n=26) and controls (n=32) were comparable in terms of age, sex, and years of education. Subjects with CBD had a mean age of 36.3 years (S.D.=15.7) and an age at onset of 19.7 years (S.D.=7.0). Compulsive buyers had more lifetime mood, anxiety, and impulse control disorders. People with Compulsive buying performed significantly better on the Wechsler Abbreviated Scale of Intelligence Picture Completion task, a test of visual perception; otherwise, there were no consistent differences in neuropsychological measures. They also had elevated levels of self-reported depression, ADHD symptoms, trait impulsivity, and novelty seeking. In conclusion, compulsive buyers have greater lifetime psychiatric comorbidity than controls, and higher levels of self-rated depression, ADHD symptoms, trait impulsivity, and novelty seeking. The present study does not support the notion that there is a pattern of neuropsychological deficits associated with CBD. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

  17. Predicting compliance with command hallucinations: anger, impulsivity and appraisals of voices' power and intent.

    Bucci, Sandra; Birchwood, Max; Twist, Laura; Tarrier, Nicholas; Emsley, Richard; Haddock, Gillian

    2013-06-01

    Command hallucinations are experienced by 33-74% of people who experience voices, with varying levels of compliance reported. Compliance with command hallucinations can result in acts of aggression, violence, suicide and self-harm; the typical response however is non-compliance or appeasement. Two factors associated with such dangerous behaviours are anger and impulsivity, however few studies have examined their relationship with compliance to command hallucinations. The current study aimed to examine the roles of anger and impulsivity on compliance with command hallucinations in people diagnosed with a psychotic disorder. The study was a cross-sectional design and included individuals who reported auditory hallucinations in the past month. Subjects completed a variety of self-report questionnaire measures. Thirty-two people experiencing command hallucinations, from both in-patient and community settings, were included. The tendency to appraise the voice as powerful, to be impulsive, to experience anger and to regulate anger were significantly associated with compliance with command hallucinations to do harm. Two factors emerged as significant independent predictors of compliance with command hallucinations; omnipotence and impulsivity. An interaction between omnipotence and compliance with commands, via a link with impulsivity, is considered and important clinical factors in the assessment of risk when working with clients experiencing command hallucinations are recommended. The data is highly suggestive and warrants further investigation with a larger sample. Copyright © 2013 Elsevier B.V. All rights reserved.

  18. 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

    2014-03-01

    Neuropeptide S and its receptor NPSR1 are involved in the regulation of arousal, attention and anxiety. We examined whether the NPSR1 gene functional polymorphism Asn¹⁰⁷Ile (rs324981, A>T) influences personality, impulsivity, and attention-deficit/hyperactivity disorder (ADHD)-related symptoms in a population-representative sample, and whether any eventual associations depend on age, sex, family relations and stressful life events (SLE). We used self-reports or teachers' ratings for both the younger (n=593) and older (n=583) cohort of the longitudinal Estonian Children Personality, Behaviour and Health Study. Males with the TT genotype displayed more ADHD-related symptoms. Adaptive impulsivity and Extraversion increased the most from age 18 to 25. While highest increases were observed in AA men, TT women exhibited the largest decreases. For participants with the AA genotype, Warmth in family was inversely associated with Neuroticism, and positively associated with Extraversion and Adaptive impulsivity. High exposure to SLE increased impulsivity and ADHD scores in TT genotype subjects. We conclude that the NPSR1 A/T polymorphism is associated with impulsivity, ADHD symptoms and personality, mirroring the activity- and anxiety-mediating role of NPSR1. Heterozygous individuals were the least sensitive to environmental factors, whereas subjects with the AA genotype and TT genotype reacted to different types of environmental adversities.

  20. The Impact of Impulsivity on Weight Loss Four Years after Bariatric Surgery

    Kathrin Schag

    2016-11-01

    Full Text Available Bariatric surgery has serious implications on metabolic health. The reasons for a failure of bariatric surgery, i.e., limited weight loss, are multifactorial and include psychological factors. We established a theoretical model of how impulsivity is related to weight loss outcome. We propose that depressive symptoms act as a mediator between impulsivity and pathological eating behavior, and that pathological eating behavior has a direct impact on weight loss outcome. We calculated excessive weight loss (%EWL and assessed self-reported impulsivity (using the Baratt Impulsiveness Scale (BIS-15 total score, depressive symptoms (the Patient Health Questionnaire (PHQ-9 score, and pathological eating behavior (the Eating Disorder Inventory 2 (EDI-2 total score in 65 patients four years after laparoscopic sleeve gastrectomy. Regression and mediation analyses were computed to validate the theoretical model. The BIS-15, PHQ-9, and EDI-2 have medium to high correlations between each other, and EDI-2 correlated with %EWL. The mediation analysis yielded that the PHQ-9 represents a significant mediator between BIS-15 and EDI-2. The regression model between EDI-2 and %EWL was also significant. These results support our theoretical model, i.e., suggest that impulsivity has an indirect impact on weight loss outcome after bariatric surgery, mediated by depression and transferred through pathological eating behavior. Thus, the underlying psychological factors should be addressed in post-operative care to optimize weight loss outcome.

  1. NORMATIVE MODERATORS OF IMPULSE BUYING BEHAVIOR

    Danes Jaya Negara

    2003-01-01

    Full Text Available Prior research has presented the moderating role of normative evaluations in the relationship between the impulsive buying trait and consumers’ buying behaviors. In this article the authors show that consumer tendency to buy something spontaneous, unreflectively and immediately can be perceived as a factor which describes buying impulsiveness. This article also shows conceptual and empirical evidence that there is some support for the moderating role of normative evaluations in the relationship between buying impulsiveness and impulse buying behaviors. Significance occurs when consumers believe that act on impulse is suitable. The result suggests that consumers’ normative evaluation can moderate the link between the trait and behavioral aspects of impulse buying.

  2. Impulsivity, "advergames," and food intake.

    Previous studies have focused on the effect of food advertisements on the caloric intake of children. However, the role of individual susceptibility in this effect is unclear. The aim of this study was to examine the role of impulsivity in the effect of advergames that promote energy-dense snacks on children's snack intake. First, impulsivity scores were assessed with a computer task. Then a randomized between-subject design was conducted with 261 children aged 7 to 10 years who played an advergame promoting either energy-dense snacks or nonfood products. As an extra manipulation, half of the children in each condition were rewarded for refraining from eating, the other half were not. Children could eat freely while playing the game. Food intake was measured. The children then completed questionnaire measures, and were weighed and measured. Overall, playing an advergame containing food cues increased general caloric intake. Furthermore, rewarding children to refrain from eating decreased their caloric intake. Finally, rewarding impulsive children to refrain from eating had no influence when they were playing an advergame promoting energy-dense snacks, whereas it did lead to reduced intake among low impulsive children and children who played nonfood advergames. Playing an advergame promoting energy-dense snacks contributes to increased caloric intake in children. The advergame promoting energy-dense snacks overruled the inhibition task to refrain from eating among impulsive children, making it more difficult for them to refrain from eating. The findings suggest that impulsivity plays an important role in susceptibility to food advertisements. Copyright © 2014 by the American Academy of Pediatrics.

  3. Relationship between self-reported adherence, antiretroviral drug concentration measurement and self-reported symptoms in patients treated for HIV-1 infection.

    The aim of the study was to explore relationships between self-reported adherence, antiretroviral drug concentration measurement (TDM) and self-reported symptoms. We systematically administered to human immunodeficiency (HIV)-infected outpatients a questionnaire evaluating measures of self-reported adherence (missing doses during last week, deviations from the prescribed timing of therapy, self-initiated discontinuations for > 24 or 48 h, exhausting drugs and present sense of how patients are taking therapy) and a panel of referred symptoms (a symptom score was built summing self-reported scores for each listed symptom). We selected patients who completed the questionnaire and also had a TDM (mainly reflecting adherence in the past few days or weeks), thus comparing these two tools as measures of adherence. A total of 130 patients (64.6% males, median age 44 years, 76.2% with HIV RNA HIV RNA symptom score was associated with a lower self-reported adherence and with a higher proportion of undetectable drug levels. Self-reported adherence and TDM showed a correlation and seemed to be comparable tools for adherence estimation. Self-reported symptoms were associated with lower adherence and undetectable drug levels.

  4. Impulsive control of time-delay systems using delayed impulse and its application to impulsive master-slave synchronization

    Sun Jitao; Han Qinglong; Jiang Xiefu

    2008-01-01

    This Letter is concerned with impulsive control of a class of nonlinear time-delay systems. Some uniform stability criteria for the closed-loop time-delay system under delayed impulsive control are derived by using piecewise Lyapunov functions. Then the criteria are applied to impulsive master-slave synchronization of some secure communication systems with transmission delays and sample delays under delayed impulsive control. Two numerical examples are given to illustrate the effectiveness of the derived results

    2017-02-01

    Attention-deficit hyperactivity disorder (ADHD) has been associated with various manifestations of impulsivity in adults, including elevated rates of other impulsive disorders, substance use, questionnaire-based impulsivity scores, and inhibitory dysregulation on neurocognitive tests. The relationship between ADHD and all these other forms of impulsivity has yet to be explored within the context of a single comprehensive study. A total of 423 young adults, who gambled ≥5 times in the preceding year, were recruited using media advertisements and undertook detailed assessment including structured psychiatric interview, questionnaires, and neurocognitive tests. Participants with ADHD symptoms were identified using the Adult ADHD Self-Report Scale Screener (ASRS-V1.1) and were compared to controls using multivariate analysis of variance (MANOVA). ADHD symptoms were found in 20.3% of the sample, but only 7.3% of these subjects had ever received a formal diagnosis. ADHD symptoms were associated with significantly lower quality of life, lower self-esteem, higher emotional dysregulation, higher impulsivity questionnaire scores, more problematic Internet use, greater occurrence of psychiatric disorders, and impaired stop-signal reaction times. Of these variables, stop-signal reaction times and Barratt attentional impulsiveness were the strongest predictors of group classification. ADHD symptoms are common and under-diagnosed in young adults who gamble, and are most strongly linked with certain other types of impulsivity (questionnaire- and cognitive-based measures) and with emotional dysregulation, suggesting that these are each important considerations in understanding the pathophysiology of the disorder, but also potential treatment targets. It is necessary to question whether treatment for adult ADHD could be enhanced by considering self-esteem, emotional reactivity, and impaired inhibitory control as specific treatment targets, in addition to the core diagnostic

    Full Text Available The reflective–impulsive model (RIM has been employed to explain various health behaviors. The present study used RIM to predict a spontaneous physical activity behavior. Specifically, 107 participants (75 females; Mage = 20.6 years, SD = 1.92 years completed measures of (1 reflections about spontaneous physical activity, as indexed by self-report questionnaire; (2 impulse toward physical activity, as indexed by the manikin task; and (3 (state self-control, as indexed by the Stroop task. The dependent variable was whether participants took the stairs or the elevator to the study laboratory. Results revealed reflections toward spontaneous physical activity positively predicted stair-taking. Further, a significant impulse toward physical activity × self-control interaction was observed. This interaction revealed that participants with high self-control who had a high impulse toward PA were more likely to take the stairs than their counterparts with a low impulse toward PA, whereas the opposite was the case for participants with low self-control. However, the impulse × self-control interaction was not significant when employing a self-report measure of trait self-control. Thus, RIM may be a good framework with which to consider spontaneous physical activity, but careful consideration must be given when examining variables within RIM (e.g., the boundary condition of self-control.

  10. Impulse: Memory System Support for Scientific Applications

    John B. Carter

    1999-01-01

    Full Text Available Impulse is a new memory system architecture that adds two important features to a traditional memory controller. First, Impulse supports application‐specific optimizations through configurable physical address remapping. By remapping physical addresses, applications control how their data is accessed and cached, improving their cache and bus utilization. Second, Impulse supports prefetching at the memory controller, which can hide much of the latency of DRAM accesses. Because it requires no modification to processor, cache, or bus designs, Impulse can be adopted in conventional systems. In this paper we describe the design of the Impulse architecture, and show how an Impulse memory system can improve the performance of memory‐bound scientific applications. For instance, Impulse decreases the running time of the NAS conjugate gradient benchmark by 67%. We expect that Impulse will also benefit regularly strided, memory‐bound applications of commercial importance, such as database and multimedia programs.

  11. Neuroanatomical and Neurochemical Basis of Impulsivity

    Kemal Yazici

    2010-08-01

    Full Text Available The term ‘impulsivity’ encompasses a multitude of behaviours that are poorly conceived, premature, inappropriate, and that frequently result in unwanted or deleterious outcomes. Impulsivity manifests as impatience carelessness, risk-taking, sensation-seeking and pleasure-seeking, an underestimated sense of harm, and extroversion. Impulsivity is a core symptom of a broad spectrum of psychiatric disorders. Through focusing on different aspects of impulsive behavior, it has proved possible to devise a variety of behavioral paradigms to measure impulsivity in both human and non-human subjects. These can be broadly divided into two categories: those measuring impulsive action or motoric impulsivity, and those measuring impulsive choice or impulsive decision-making. Impulsive action can be broadly defined as the inability to withhold from making a response. Within the framework of behavioral neuroscience and cognitive psychology, impulse control has been described as an active inhibitory mechanism which modulates the internally or externally driven pre-potent desire for primary reinforcers such as food, sex or other highly desirable rewards. This inhibitory control mechanism may provide the substrate by which rapid conditioned responses and reflexes are transiently suppressed, so that slower cognitive mechanisms can guide behavior. This process is referred to as response inhibition. Two of the most common tests used to study inhibitory processes are the go/no-go and stop-signal reaction time tasks. Impulsivity is also evident in the making of impulsive decisions or choices as well as in impulsive actions. Here, there is no “pre-potent” response that is primed and then forcibly inhibited, but a decision-making processes. Impulsive decision making or impulsive choice is defined as initiating actions without adequately considering other possible choices or consequences. Impulsive choice is typically measured in the delay discounting paradigm. In

  12. Validity and reliability of the attention deficit hyperactivity disorder self-report scale (ASRS-v1.1) in a clinical sample with eating disorders.

    Carlucci, Samantha; Ivanova, Iryna; Bissada, Hany; Tasca, Giorgio A

    2017-08-01

    Individuals with eating disorders (EDs) commonly experience comorbid attention deficit hyperactivity disorder (ADHD). The shared features of EDs and ADHD, such as inattention, impulsivity and hyperactivity, may exacerbate ED symptomatology and pose challenges to treatment. It is important to screen patients with EDs for symptoms of ADHD to optimize their treatment outcomes. However, the psychometrics of common measures of ADHD have not yet been examined within an ED population. An example of such a measure is the ADHD self-report scale (ASRS-v1.1) symptom checklist, which identifies the presence of ADHD symptoms. This study reports a psychometric study of the ASRS-v1.1 in a clinical sample of 500 adults with an ED. A confirmatory factor analysis indicated the ASRS-v1.1 maintained its two-factor structure of inattention and impulsivity/hyperactivity. The item loadings demonstrated path invariance across ED diagnostic groups indicating construct validity. Further, the subscales exhibited good internal consistency and they were significantly correlated with other measures of impulsivity indicating convergent validity. The ED sample had significantly higher mean scores than published nonclinical norms indicating predictive validity, but the ASRS-v1.1 scores were not significantly different among ED diagnostic groups. Results suggest the ASRS-v1.1 is a valid and reliable screening tool for identifying symptoms of ADHD among adults seeking treatment for ED. Copyright © 2017 Elsevier Ltd. All rights reserved.

  13. Impulse sales cooler. Final report

    Pedersen, Per Henrik (DTI, Taastrup (Denmark))

    2010-11-15

    In the past years, the use of impulse coolers has increased considerably and it is estimated that at least 30.000 are installed in shops in Denmark. In addition, there are many small barrel-shaped can coolers. Most impulse coolers are open, which results in a large consumption of energy, and the refrigeration systems are often quite inefficient. A typical impulse cooler uses app. 5 - 8 kWh/day corresponding to a consumption of energy in the magnitude of 60 GWh/year. For several years, the Danish company Vestfrost A/S has produced an impulse sales cooler in the high-efficiency end and the energy consumption of the cooler is measured to be 4.15 kWh/day. The POS72 cooler formed the baseline of this project. At the start-up meeting in 2008, several ideas were discussed with the objective to reduce energy consumption and to use natural refrigerants. Among the ideas were better air curtains, removable lids, better condensers, use of R600a refrigeration system and better insulation. Three generations of prototypes were built and tested in a climate chamber at Danish Technological Institute and the third generation showed very good performance: the energy consumption was measured to 2.215 kWh/day, which is a 47% reduction compared to the baseline. That was achieved by: 1) Improving the cold air cycling system including the air curtain. 2) Using the natural refrigerant R600a (isobutane) and the Danfoss NLE9KTK compressor, which has better efficiency compared to the compressor in the baseline product. 3) Using a box type condenser without fins (preventing dust build-up) and with a relatively high surface area. 4) Improving the insulation value of the plastic cabinet by reducing turbulence in the air gap between the plastic walls and improving the insulation value of the EPS moulded insulation surrounding the refrigeration system at the bottom of the cooler. 5) Preventing short-circuit of warm air around the condenser. 6) The improvements are cost efficient and will not add

    2012-01-01

    Prospective analysis was performed of self-reported and biochemically confirmed tobacco use in 50 head and neck cancer patients during treatment. With 93.5% compliance to complete weekly self-report and biochemical confirmatory tests, 29.4% of smokers required biochemical assessment for identification. Accuracy increased by 14.9% with weekly vs. baseline self-reported assessments. Data confirm that head and neck cancer patients misrepresent true tobacco use during treatment.

  18. Prescribed and self-reported seasonal training of distance runners.

    Hewson, D J; Hopkins, W G

    1995-12-01

    A survey of 123 distance-running coaches and their best runners was undertaken to describe prescribed seasonal training and its relationship to the performance and self-reported training of the runners. The runners were 43 females and 80 males, aged 24 +/- 8 years (mean +/- S.D.), training for events from 800 m to the marathon, with seasonal best paces of 86 +/- 6% of sex- and age-group world records. The coaches and runners completed a questionnaire on typical weekly volumes of interval and strength training, and typical weekly volumes and paces of moderate and hard continuous running, for build-up, pre-competition, competition and post-competition phases of a season. Prescribed training decreased in volume and increased in intensity from the build-up through to the competition phase, and had similarities with 'long slow distance' training. Coaches of the faster runners prescribed longer build-ups, greater volumes of moderate continuous running and slower relative paces of continuous running (r = 0.19-0.36, P training close to competition pace. The mean training volumes and paces prescribed by the coaches were similar to those reported by the runners, but the correlations between prescribed and reported training were poor (r = 0.2-0.6). Coaches may therefore need to monitor their runners' training more closely.

    Burnout is a work-related syndrome that may negatively affect more than just the resident physician. On the other hand, engagement has been shown to protect employees; it may also positively affect the patient care that the residents provide. Little is known about the relationship between residents' self-reported errors and burnout and engagement. In our national study that included all residents and physicians in The Netherlands, 2115 questionnaires were returned (response rate 41.1%). The residents reported on burnout (Maslach Burnout Inventory-Health and Social Services), engagement (Utrecht Work Engagement Scale) and self-assessed patient care practices (six items, two factors: errors in action/judgment, errors due to lack of time). Ninety-four percent of the residents reported making one or more mistake without negative consequences for the patient during their training. Seventy-one percent reported performing procedures for which they did not feel properly trained. More than half (56%) of the residents stated they had made a mistake with a negative consequence. Seventy-six percent felt they had fallen short in the quality of care they provided on at least one occasion. Men reported more errors in action/judgment than women. Significant effects of specialty and clinical setting were found on both types of errors. Residents with burnout reported significantly more errors (p engaged residents reported fewer errors (p burnout and to keep residents engaged in their work.

  20. Athlete Self-Report Measure Use and Associated Psychological Alterations

    Anna E. Saw

    2017-07-01

    Full Text Available The experience of athletes and practitioners has led to the suggestion that use of an athlete self-report measure (ASRM may increase an athlete’s self-awareness, satisfaction, motivation, and confidence. This study sought to provide empirical evidence for this assertion by evaluating psychological alterations associated with ASRM use across a diverse athlete population. Athletes (n = 335 had access to an ASRM for 16 weeks and completed an online survey at baseline, and weeks 4, 8, and 16. Generalized estimating equations were used to evaluate the associations between ASRM compliance and outcome measures. Compared to baseline, confidence and extrinsic motivation were most likely increased at weeks 4, 8, and 16. Satisfaction and intrinsic motivation were most likely decreased at week 4, but no different to baseline values at weeks 8 and 16. Novice athletes and those who were instructed to use an ASRM (rather than using one autonomously were less responsive to ASRM use. This study provides preliminary evidence for ASRM to prompt initial dissatisfaction and decreased intrinsic motivation which, along with increased confidence and extrinsic motivation, may provide the necessary stimulus to improve performance-related behaviors. Novice and less autonomous athletes may benefit from support to develop motivation, knowledge, and skills to use the information gleaned from an ASRM effectively.

  1. Cultural values: can they explain self-reported health?

    Roudijk, Bram; Donders, Rogier; Stalmeier, Peep

    2017-06-01

    Self-reported health (SRH) is a measure widely used in health research and population studies. Differences in SRH have been observed between countries and cultural values have been hypothesized to partly explain such differences. Cultural values can be operationalized by two cultural dimensions using the World Values Survey (WVS), namely the traditional/rational-secular and the survival/self-expression dimension. We investigate whether there is an association between the WVS cultural dimensions and SRH, both within and between countries. Data from 51 countries in the WVS is used and combined with macroeconomic data from the Worldbank database. The association between SRH and the WVS cultural dimensions is tested within each of the 51 countries and multilevel mixed models are used to test differences between these countries. Socio-demographic and macroeconomic variables are used to correct for non-cultural variables related to SRH. Within countries, the survival/self-expression dimension was positively associated with SRH, while in most countries there was a negative association for the traditional/rational-secular dimension. Values range between 4 and 17% within countries. Further analyses show that the associations within countries and between countries are similar. Controlling for macroeconomic and socio-demographic factors did not change our results. The WVS cultural dimensions predict SRH within and between countries. Contrary to our expectations, traditional/rational-secular values were negatively associated with SRH. As SRH is associated with cultural values between countries, cultural values could be considered when interpreting SRH between countries.

  2. Leadership: validation of a self-report scale.

    Dussault, Marc; Frenette, Eric; Fernet, Claude

    2013-04-01

    The aim of this paper was to propose and test the factor structure of a new self-report questionnaire on leadership. A sample of 373 school principals in the Province of Quebec, Canada completed the initial 46-item version of the questionnaire. In order to obtain a questionnaire of minimal length, a four-step procedure was retained. First, items analysis was performed using Classical Test Theory. Second, Rasch analysis was used to identify non-fitting or overlapping items. Third, a confirmatory factor analysis (CFA) using structural equation modelling was performed on the 21 remaining items to verify the factor structure of the scale. Results show that the model with a single third-order dimension (leadership), two second-order dimensions (transactional and transformational leadership), and one first-order dimension (laissez-faire leadership) provides a good fit to the data. Finally, invariance of factor structure was assessed with a second sample of 222 vice-principals in the Province of Quebec, Canada. This model is in agreement with the theoretical model developed by Bass (1985), upon which the questionnaire is based.

  3. Self-reported emotion regulation in adults with Tourette's syndrome.

    Drury, Helena; Wilkinson, Verity; Robertson, Mary M; Channon, Shelley

    2016-11-30

    Recent work has reported mild impairments in social and emotional processing in Tourette's syndrome (TS), but deliberate attempts to use specific emotion regulation strategies have not been investigated previously. In the present study, adult participants with TS and no comorbidities (TS-alone) were compared to healthy control participants on several self-report measures assessing habitual use of reappraisal and suppression emotion regulation strategies. There were no group differences on measures of reappraisal, but the TS-alone group reported using suppression more frequently than the control group and this was true across a range of negative emotions. The groups did not differ on symptomatology scores of anxiety or depression, although more frequent use of suppression was associated with higher depressive symptomatology for the TS-alone group only. Further work is needed to examine potential factors that may influence emotion regulation in TS, including increased emotional reactivity or expertise in applying strategies to suppress tic symptoms.

    Conrad, Kendon J; Iris, Madelyn; Ridings, John W; Langley, Kate; Wilber, Kathleen H

    2010-12-01

    this study was designed to improve the measurement of financial exploitation (FE) by testing psychometric properties of the older adult financial exploitation measure (OAFEM), a client self-report instrument. rasch item response theory and traditional validation approaches were used. Questionnaires were administered by 22 adult protective services investigators from 7 agencies in Illinois to 227 substantiated abuse clients. Analyses included tests for dimensionality, model fit, and additional construct validation. Results from the OAFEM were also compared with the substantiation decision of abuse and with investigators' assessments of FE using a staff report version. Hypotheses were generated to test hypothesized relationships. the OAFEM, including the original 79-, 54-, and 30-item measures, met stringent Rasch analysis fit and unidimensionality criteria and had high internal consistency and item reliability. The validation results were supportive, while leading to reconsideration of aspects of the hypothesized theoretical hierarchy. Thresholds were suggested to demonstrate levels of severity. the measure is now available to aid in the assessment of FE of older adults by both clinicians and researchers. Theoretical refinements developed using the empirically generated item hierarchy may help to improve assessment and intervention.

  5. The properties of self-report research measures: beyond psychometrics.

    Blount, Claire; Evans, Chris; Birch, Sarah; Warren, Fiona; Norton, Kingsley

    2002-06-01

    Self-report measures pertinent for personality disorder are widely used and many are available. Their relative merits are usually assessed on nomothetic psychometrics and acceptability to users is neglected. We report reactions of lay, patient and professional groups to the Personality Diagnostic Questionnaire (PDQ-IV); Millon Clinical Multiaxial Inventory (MCMI-III); the Borderline Syndrome Index (BSI); Rosenberg's Self-Esteem Scale (RSE) and the Social Functioning Questionnaire (SFQ). These were sent to 148 professionals, ex-patients and lay people for comment. Thirty-six per cent were returned. Pattern-coding by three raters revealed problematic themes across all measures, including inappropriate length, vague items and language, cultural assumptions and slang, state-bias and response-set. Measures can be depressing and upsetting for some participants (both patients and non-patients), hence administration of measures should be sensitive. Treatment may make people more self-aware, which may compromise validity for outcome research. This evaluation raises issues and concerns, which are missed in traditional psychometric evaluation.

  6. Nano-in-Micro Self-Reporting Hydrogel Constructs.

    Tirella, Annalisa; La Marca, Margherita; Brace, Leigh-Anne; Mattei, Giorgio; Aylott, Jonathan W; Ahluwalia, Arti

    2015-08-01

    Highly reproducible Nano-in-Micro constructs are fabricated to provide a well-defined and self-reporting biomimetic environment for hepatocytes. Based on a protein/hydrogel formulation with controlled shape, size and composition, the constructs enable efficient nutrient exchange and provide an adhesive 3D framework to cells. Co-encapsulation of hepatocytes and ratiometric optical nanosensors with pH sensitivity in the physiological range allows continuous monitoring of the microenvironment. The lobule-sized microbeads are fabricated using an automated droplet generator, Sphyga (Spherical Hydrogel Generator) combining alginate, collagen, decellularized hepatic tissue, pH-nanosensors and hepatocytes. The pH inside the Nano-in-Micro constructs is monitored during culture, while assaying media for hepatic function and vitality markers. Although the local pH changes by several units during bead fabrication, when encapsulated cells are most likely to undergo stress, it is stable and buffered by cell culture media thereafter. Albumin secretion and urea production are significantly higher in the microbeads compared with controls, indicating that the encapsulated Nano-in-Micro environment is conducive to enhanced hepatic function.

    2013-01-01

    Full Text Available The impulsive synchronization and adaptive-impulsive synchronization of a novel financial hyperchaotic system are investigated. Based on comparing principle for impulsive functional differential equations, several sufficient conditions for impulsive synchronization are derived, and the upper bounds of impulsive interval for stable synchronization are estimated. Furthermore, a nonlinear adaptive-impulsive control scheme is designed to synchronize the financial system using invariant principle of impulsive dynamical systems. Moreover, corresponding numerical simulations are presented to illustrate the effectiveness and feasibility of the proposed methods.

  9. The mediating role of non-suicidal self-injury in the relationship between impulsivity and suicidal behavior among inpatients receiving treatment for substance use disorders.

    Anestis, Michael D; Tull, Matthew T; Lavender, Jason M; Gratz, Kim L

    2014-08-15

    Several theories posit a direct role of impulsivity in suicidal behavior. The interpersonal-psychological theory of suicidal behavior (IPTS) argues that the relationship between impulsivity and suicidal behavior is explained by the painful and/or provocative experiences (PPEs) often encountered by impulsive individuals. It thus seems plausible that nonsuicidal self-injury (NSSI), itself associated with impulsivity, might account for the relationship between impulsivity and suicidal behavior. We examined data from 93 adult inpatients (54.8% male) seeking treatment for substance use disorders. Patients completed a structured interview assessing prior suicidal behavior and a series of self-report questionnaires examining impulsivity, NSSI, and psychopathology. Four impulsivity dimensions (negative urgency, positive urgency, lack of premeditation, lack of perseverance) were associated with lifetime number of suicide attempts and/or suicide potential. Furthermore, results supported our hypotheses, as all but one relation was better accounted for by NSSI and, in the one exception, the direct effect was non-significant. Findings are consistent with the IPTS and suggest that suicidal behavior may not be a direct manifestation of impulsivity, but facilitated through exposure to PPEs capable of altering an individual׳s relationship to pain and fear of death.

  10. Modern day addictions: The role of temptations in a reflective-impulsive-interoceptive awareness model of information system use

    Ofir eTurel

    2016-04-01

    Full Text Available This study examines a behavioral tripartite model developed in the field of addiction, and applied here to understanding general and impulsive information technology use. It suggests that technology use is driven by two information-processing brain systems: reflective and impulsive, and that their effects on use are modulated by interoceptive awareness processes. The resultant reflective-impulsive-interoceptive awareness model is tested in two behavioral studies. Both studies employ SEM techniques to time-lagged self-report data from n1=300 and n2=369 social networking site users. Study 1 demonstrated that temptations augment the effect of habit on technology use, and reduce the effect of satisfaction on use. Study 2 showed that temptations strengthen the effect of habit on impulsive technology use, and weaken the effect of behavioral expectations on impulsive technology use. Hence, the results consistently support the notion that information technology users’ behaviors are influenced by reflective and impulsive information processing systems; and that the equilibrium of these systems is determined, at least in part, by one’s temptations. These results can serve as a basis for understanding the etiology of modern day addictions.

  11. Relationship between Self-Reported Dietary Nutrient Intake and Self-Reported Sleep Duration among Japanese Adults

    Yoko Komada

    2017-02-01

    Full Text Available Several studies have reported that short sleep duration is a risk factor for obesity and metabolic disease. Moreover, both sleep duration and sleep timing might independently be associated with dietary nutrient intake. In this study, we investigated the associations between self-reported sleep duration and dietary nutrient intake, with and without adjustments for variations in sleep timing (i.e., the midpoint of sleep. We conducted a questionnaire survey, comprising a validated brief self-administered diet history questionnaire (BDHQ and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI among 1902 healthy Japanese adults and found that the dietary intakes of several nutrients correlated with sleep duration among men regardless of adjustment for the midpoint of sleep. Particularly, (1 small but significant correlations were observed between sleep duration and the percentage of energy from protein, regardless of adjustment for the midpoint of sleep; (2 energy-adjusted intakes of sodium, vitamin D, and vitamin B12 also significantly correlated with sleep duration; and (3 intakes of bread, pulses, and fish and shellfish correlated with sleep duration. In contrast, no significant correlations were observed between sleep duration and dietary intakes among women. This study revealed that after controlling for the midpoint of sleep, sleep duration correlated significantly with the dietary intake of specific nutrients and foods in a population of Japanese men.

  12. Impulse generation by detonation tubes

    Cooper, Marcia Ann

    Impulse generation with gaseous detonation requires conversion of chemical energy into mechanical energy. This conversion process is well understood in rocket engines where the high pressure combustion products expand through a nozzle generating high velocity exhaust gases. The propulsion community is now focusing on advanced concepts that utilize non-traditional forms of combustion like detonation. Such a device is called a pulse detonation engine in which laboratory tests have proven that thrust can be achieved through continuous cyclic operation. Because of poor performance of straight detonation tubes compared to conventional propulsion systems and the success of using nozzles on rocket engines, the effect of nozzles on detonation tubes is being investigated. Although previous studies of detonation tube nozzles have suggested substantial benefits, up to now there has been no systematic investigations over a range of operating conditions and nozzle configurations. As a result, no models predicting the impulse when nozzles are used exist. This lack of data has severely limited the development and evaluation of models and simulations of nozzles on pulse detonation engines. The first experimental investigation measuring impulse by gaseous detonation in plain tubes and tubes with nozzles operating in varying environment pressures is presented. Converging, diverging, and converging-diverging nozzles were tested to determine the effect of divergence angle, nozzle length, and volumetric fill fraction on impulse. The largest increases in specific impulse, 72% at an environment pressure of 100 kPa and 43% at an environment pressure of 1.4 kPa, were measured with the largest diverging nozzle tested that had a 12° half angle and was 0.6 m long. Two regimes of nozzle operation that depend on the environment pressure are responsible for these increases and were first observed from these data. To augment this experimental investigation, all data in the literature regarding

  13. Are self-reports of health and morbidities in developing countries misleading? Evidence from India.

    Subramanian, S V; Subramanyam, Malavika A; Selvaraj, Sakthivel; Kawachi, Ichiro

    2009-01-01

    Self-reported measures of poor health and morbidities from developing countries tend to be viewed with considerable skepticism. Examination of the social gradient in self-reported health and morbidity measures provides a useful test of the validity of self-reports of poor health and morbidities. The prevailing view, in part influenced by Amartya Sen, is that socially disadvantaged individuals will fail to perceive and report the presence of illness or health-deficits because an individual's assessment of their health is directly contingent on their social experience. In this study, we tested whether the association between self-reported poor health/morbidities and socioeconomic status (SES) in India follows the expected direction or not. Cross-sectional logistic regression analyses were carried out on a nationally representative population-based sample from the 1998 to 1999 Indian National Family Health Survey (INFHS); and 1995-1996 and 2004 Indian National Sample Survey (INSS). Four binary outcomes were analyzed: any self-reported morbidity; self-reported sickness in the last 15 days; self-reported sickness in the past year; and poor self-rated health. In separate adjusted models, individuals with no education reported higher levels of any self-reported, self-reported sickness in the last 15 days, self-reported sickness in the last year, and poor self-rated health compared to those with most education. Contrary to the prevailing thesis, we find that the use of self-rated ill-health has face validity as assessed via its relationship to SES. A less dismissive and pessimistic view of health data obtained through self-reports seems warranted.

    Women can experience symptoms of gingival inflammation during pregnancy. However, whether clinical signs of gingival inflammation were present already before pregnancy and whether women perceive an alteration in their periodontal health status during pregnancy compared to their periodontal health status before pregnancy remain unclear. The aim of this study was to evaluate the self-reported periodontal conditions in pregnant Dutch women as perceived before and during pregnancy. This cross-sectional survey was performed by asking women visiting two midwifery practices to complete a structured questionnaire. The data, which considered the women's oral hygiene habits, perceived periodontal health status before and during pregnancy and dental visits, were gathered and analysed. Parametric and nonparametric tests were used when appropriate. Most of the respondents (mean age: 29.6 years) brushed their teeth twice a day (72.2%), and 62.0% used interdental cleaning devices. Significant differences in periodontal health before and during pregnancy were perceived. No differences with respect to periodontal disease symptoms between the three trimesters during pregnancy were found. The symptom with the greatest increase was bleeding gums. This was followed by symptoms of painful and swollen gums. Of the 61.5% women who disclosed their plans to become pregnant to their dental care practitioner, 53.9% received information regarding the possibility of alterations in oral health status during pregnancy. Because of the perceived alterations in oral health status during pregnancy, approximately 11% of the women scheduled an additional appointment with their dental care professional for advice. During the pregnancy period, perceived alterations in periodontal health status were reported as compared to the oral health situation before pregnancy. Furthermore, approximately 50% of the women who visited a dental professional and disclosed their (plans) of pregnancy did not receive

    Sexual orientation is usually considered to be determined in early life and stable in the course of adulthood. In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known. We included 115 transsexual persons (70 male-to-female "MtF" and 45 female-to-male "FtM") patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase. The questionnaire focused on sexual orientation and recalled time points of changes in sexual orientation in the context of transition. Participants were further asked to provide a personal concept for a potential change in sexual orientation. In total, 32.9% (n = 23) MtF reported a change in sexual orientation in contrast to 22.2% (n = 10) FtM transsexual persons (p = 0.132). Out of these patients, 39.1% (MtF) and 60% (FtM) reported a change in sexual orientation before having undergone any sex reassignment surgery. FtM that had initially been sexually oriented towards males ( = androphilic), were significantly more likely to report on a change in sexual orientation than gynephilic, analloerotic or bisexual FtM (p = 0.012). Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p =0.05). In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may explain this phenomenon.

  16. Self-Reported Mental Health Predicts Acute Respiratory Infection.

    2015-06-01

    Poor mental health conditions, including stress and depression, have been recognized as a risk factor for the development of acute respiratory infection. Very few studies have considered the role of general mental health in acute respiratory infection occurrence. The aim of this analysis is to determine if overall mental health, as assessed by the mental component of the Short Form 12 Health Survey, predicts incidence, duration, or severity of acute respiratory infection. Data utilized for this analysis came from the National Institute of Health-funded Meditation or Exercise for Preventing Acute Respiratory Infection (MEPARI) and MEPARI-2 randomized controlled trials examining the effects of meditation or exercise on acute respiratory infection among adults aged > 30 years in Madison, Wisconsin. A Kendall tau rank correlation compared the Short Form 12 mental component, completed by participants at baseline, with acute respiratory infection incidence, duration, and area-under-the-curve (global) severity, as assessed by the Wisconsin Upper Respiratory Symptom Survey. Participants were recruited from Madison, Wis, using advertisements in local media. Short Form 12 mental health scores significantly predicted incidence (P = 0.037) of acute respiratory infection, but not duration (P = 0.077) or severity (P = 0.073). The Positive and Negative Affect Schedule (PANAS) negative emotion measure significantly predicted global severity (P = 0.036), but not incidence (P = 0.081) or duration (P = 0.125). Mindful Attention Awareness Scale scores significantly predicted incidence of acute respiratory infection (P = 0.040), but not duration (P = 0.053) or severity (P = 0.70). The PHQ-9, PSS-10, and PANAS positive measures did not show significant predictive associations with any of the acute respiratory infection outcomes. Self-reported overall mental health, as measured by the mental component of Short Form 12, predicts acute respiratory infection incidence.

  17. Stereotype Threat Lowers Older Adults' Self-Reported Hearing Abilities.

    Barber, Sarah J; Lee, Soohyoung Rain

    2015-01-01

    Although stereotype threat is a well-documented phenomenon, previous studies examining it in older adults have almost exclusively focused on objective cognitive outcomes. Considerably less attention has been paid to the impact of stereotype threat on older adults' subjective assessments of their own abilities or to the impact of stereotype threat in noncognitive domains. Older adults are stereotyped as having experienced not only cognitive declines, but physical declines as well. The current study tested the prediction that stereotype threat can negatively influence older adults' subjective hearing abilities. To test this, 115 adults (mean age 50.03 years, range 41-67) read either a positive or negative description about how aging affects hearing. All participants then answered a questionnaire in which they assessed their own hearing abilities. The impact of stereotype threat on self-reported hearing was moderated by chronological age. Participants in their 40s and early 50s were unaffected by the stereotype threat manipulation. In contrast, participants in their late 50s and 60s rated their hearing as being subjectively worse when under stereotype threat. The current study provides a clear demonstration that stereotype threat negatively impacts older adults' subjective assessments of their own abilities. It is also the first study to demonstrate an effect of stereotype threat within the domain of hearing. These results have important implications for researchers investigating age-related hearing decline. Stereotype threat can lead to overestimation of the prevalence of age-related hearing decline. It can also serve as a confounding variable when examining the psychosocial correlates of hearing loss. Because of this, researchers studying age-related hearing loss should aim to provide a stereotype threat-free testing environment and also include assessments of stereotype threat within their studies. © 2015 S.

Considerably less attention has been paid to the impact of stereotype threat on older adults’ subjective assessments of their own abilities or to the impact of stereotype threat in non-cognitive domains. Objective Older adults are stereotyped as having experienced not only cognitive declines, but physical declines as well. The current study tested the prediction that stereotype threat can negatively influence older adult's subjective hearing abilities. Methods To test this, 115 adults (M age = 50.02, range = 41-67) read either a positive or negative description about how aging affects hearing. All participants then answered a questionnaire in which they assessed their own hearing abilities. Results The impact of stereotype threat on self-reported hearing was moderated by chronological age. Participants in their 40's and early 50's were unaffected by the stereotype threat manipulation. In contrast, participants in their late 50's and 60's rated their hearing as being subjectively worse when under stereotype threat.

    Suicide attempt is a risk factor for suicide. To investigate trait impulsivity among suicide attempters, 93 attempters admitted to an emergency department and 113 healthy controls were evaluated using the Japanese version of the Barratt Impulsiveness Scale (BIS-11J). Impulsivity was analyzed in relation to clinical data in the attempters. Total BIS-11J, attention impulsiveness, and motor impulsiveness scores were significantly higher in the attempters than in the controls. Both total BIS-11J and non-planning impulsiveness scores were significantly higher in attempters with schizophrenia and other psychotic disorders among the diagnostic groups. Control of impulsivity should be considered as one of the targets for suicide prevention. © 2012 The Authors.

  20. Anger biting. The hidden impulse.

    Walter, R D

    1985-09-01

    Based upon the paralogical reasoning of the anger-impulsive biter, this paper addresses the overload of emotional catharsis which can block a full memory of the biting event and suspend the logical infrastructure of rational behavior. In an effort to overcome these types of investigative difficulties, the paper suggests an approach to resolve dilemma through decompressing the emotional content into path ways of logical understanding. By offering a network of rationale hooks, the perpetrator becomes better equipped to acknowledge the deed.

  9. Self-reported difficulty in conceiving as a measure of infertility.

    Dick, M-L B; Bain, C J; Purdie, D M; Siskind, V; Molloy, D; Green, A C

    2003-12-01

    This study aimed to explore the meaning and potential use of women's self-reported difficulties in conceiving as a measure of infertility in epidemiological studies, and to compare women's stated reasons for infertility with information in their medical records. Data were available from a population-based case-control study of ovarian cancer involving 1638 women. The sensitivity and specificity of women's self-reported infertility were calculated against their estimated fertility status based on detailed reproductive histories. Self-reported reasons for infertility were compared with diagnoses documented in women's medical records. The sensitivity of women's self-reported difficulty in conceiving was 66 and 69% respectively when compared with calendar-derived and self-reported times taken trying to conceive; its specificity was 95%. Forty-one (23%) of the 179 women for whom medical records were available had their self-reported fertility problem confirmed. Self-reported infertility causes could be compared with diagnoses in medical records for only 22 of these women. Self-reported difficulty conceiving is a useful measure of infertility for quantifying the burden of fertility problems experienced in the community. Validation of reasons for infertility is unlikely to be feasible through examination of medical records. Improved education of the public regarding the availability and success rates of infertility treatments is proposed.

    Inconsistent results have been found in prior studies investigating the accuracy of self-reported waist circumference, and no study has investigated the validity of self-reported waist circumference among Japanese individuals. This study used the diagnostic standard of metabolic syndrome to assess the accuracy of individual's self-reported height, weight and waist circumference in a Japanese sample. Study participants included 7,443 Japanese men and women aged 35-79 years. They participated in a cohort study's baseline survey between 2007 and 2011. Participants' height, weight and waist circumference were measured, and their body mass index was calculated. Self-reported values were collected through a questionnaire before the examination. Strong correlations between measured and self-reported values for height, weight and body mass index were detected. The correlation was lowest for waist circumference (men, 0.87; women, 0.73). Men significantly overestimated their waist circumference (mean difference, 0.8 cm), whereas women significantly underestimated theirs (mean difference, 5.1 cm). The sensitivity of self-reported waist circumference using the cut-off value of metabolic syndrome was 0.83 for men and 0.57 for women. Due to systematic and random errors, the accuracy of self-reported waist circumference was low. Therefore, waist circumference should be measured without relying on self-reported values, particularly in the case of women.

  4. Alcohol use, depressive symptoms, and impulsivity as risk factors for suicide proneness among college students.

    Dvorak, Robert D; Lamis, Dorian A; Malone, Patrick S

    2013-07-01

    Alcohol use, depression, and suicide are significant public health problems, particularly among college students. Impulsivity is associated with all of these factors. Additionally, impulsivity increases the effects of negative mood and alcohol use on maladaptive behavior. The current cross-sectional study examined the association between the four-factor model of impulsivity (urgency, (lack of) perseverance, (lack of) premeditation, and sensation seeking), depressive symptoms, and alcohol use as predictors of suicide proneness among college students. Participants (n=1100) completed online assessments of demographics, impulsivity, depressive symptoms, and suicide proneness. All predictors were positively related to suicide proneness. The relation between depressive symptoms and suicide proneness was moderated by (lack of) perseverance, alcohol use, and joint interactions of urgency×alcohol use and sensation seeking×alcohol use. Despite some paradoxical findings regarding the depressive symptoms-suicide proneness relation when only one risk factor was elevated, the average level of suicide proneness increased as risk factors increased. This cross-sectional self-report data comes from a non-clinical sample of college students from a homogeneous background, limiting generalizability and causal predictions. Overall, these findings indicate that the association between depressive symptoms and suicide proneness varies considerably by different facets of impulsivity and alcohol use. The results suggest that clinical risk-assessments should weigh two forms of impulsivity (urgency and sensation seeking) as particularly vital in the presence of heavy alcohol use. These findings highlight the importance of considering and exploring moderators of the mood-suicide relationship. Copyright © 2013 Elsevier B.V. All rights reserved.

  5. The effects of trait impulsivity on proactive and reactive interference control.

    Xiang, Ling; Chen, Yan; Chen, Antao; Zhang, Fenghua; Xu, Fuming; Wang, Baoxi

    2018-02-01

    The current study used event-related brain potentials (ERPs) to explore whether self-reported trait impulsivity in healthy individuals might be differentially related to proactive and reactive interference control. Participants with high and low impulsivity (HI and LI, respectively) performed a modified version of the prime-target interference task. Proactive interference control was induced in the mostly incongruent (MI) context and reactive interference control was induced in the mostly congruent (MC) context. Although the behavioral data revealed no difference between HI and LI individuals in terms of the interference effects (incongruent - congruent) under both contexts, the ERP results showed that impulsivity has a different influence on the interference effects under different task contexts. In the MC context, the interference effects on the medial frontal negativity (MFN) and the negative sustained potential (N-SP) were greater, while that on the positive sustained potential (P-SP) were smaller in the HI compared to those in the LI group. This suggests that high levels of impulsivity might be associated with a reduced efficiency of the processes supporting reactive control to resolve interference when interference is not expected. In contrast, the three ERP indices (MFN, P-SP, and N-SP) of interference processing in the MI context were insensitive to variations in impulsivity. This suggests that HI individuals might be as effective as LI individuals in recruiting proactive control for sustained active maintenance of task goals to anticipate and prevent interference throughout the experimental blocks where interference occurs frequently. In conclusion, these results indicate that impulsivity has a more negative influence on reactive interference control than on proactive interference control. Copyright © 2017.

  6. Impulsivity and history of behavioral addictions are associated with drug use in adolescents.

    Chuang, Cheng-Wei I; Sussman, Steve; Stone, Matthew D; Pang, Raina D; Chou, Chih-Ping; Leventhal, Adam M; Kirkpatrick, Matthew G

    2017-11-01

    Previous literature suggests that trait impulsivity and engagement in non-drug-related behavioral addictions (e.g., Internet addiction, food addiction) are two risk factors for drug use. Here we further investigated the potential impact of having one or both of these risk factors on drug use in Los Angeles area adolescents. High school students (N=1612; Mean age=14.1) completed self-report surveys measuring two potential risk factors (impulsivity, lifetime history of several behavioral addictions), and past 6-month use of tobacco, alcohol and marijuana. Participants who reported never using drugs completed questionnaires assessing their susceptibility for future use. In general, adolescents who endorsed either impulsivity alone or at least two behavioral addictions alone were more likely to have used tobacco, alcohol, or marijuana compared to individuals who had neither risk factor (OR=2.50-4.13), and individuals who endorsed both impulsivity and three or more behavioral addictions were the most likely to have used these drugs (OR=9.40-10.13). Similarly, among those who had never tried a drug, individuals with this combined set of risk factors were the most likely to be susceptible to future drug use (OR=3.37-5.04). These results indicate that the combination of trait impulsivity and a history of behavioral addictions increases the risk for current and future drug use in adolescents, to a greater extent than either risk factor alone. It may be useful for drug prevention efforts to target impulsive adolescents who also actively engage in other non-drug-related addictive behaviors. Copyright © 2017 Elsevier Ltd.

  7. Time perception, impulsivity, emotionality, and personality in self-harming borderline personality disorder patients.

    Berlin, Heather A; Rolls, Edmund T

    2004-08-01

    To investigate how time perception may contribute to the symptoms of self-harming Borderline Personality Disorder (BPD) patients, 19 self-harming BPD inpatients and 39 normal controls were given measures of time perception, impulsivity, personality, emotion, and BPD characteristics. A test sensitive to orbitofrontal cortex (OFC) function ("Frontal" Behavior Questionnaire) was also administered, as the OFC has been associated with impulsivity and time perception. BPD patients produced less time than controls, and this correlated with impulsiveness and other characteristics commonly associated with BPD. BPD patients were also less conscientious, extraverted, and open to experience, as well as more impulsive (self-report and behaviorally), emotional, neurotic, and reported more BPD characteristics, compared to controls. The results suggest that some of these core characteristics of BPD may be on a continuum with the normal population and, impulsivity in particular, may be related to time perception deficits (i.e., a faster subjective sense of time). Finally, BPD patients scored higher on the Frontal Behavior Questionnaire, suggesting that some symptoms of the BPD syndrome may be related to problems associated with the OFC. A control spatial working memory task (SWM) revealed that SWM deficits could not explain any of the BPD patients' poor performance. While impulsivity was correlated with time perception across all participants, emotionality, introversion, and lack of openness to experience were not. This suggests that different symptoms of the borderline personality syndrome may be separable, and therefore, related to different cognitive deficits, and potentially to different brain systems. This may have important implications for treatment strategies for BPD.

    Compulsive buying (CB) is currently classified as an impulse control disorder (ICD) not otherwise classified. Compulsive buying prevalence is estimated at around 5% of the general population. There is controversy about whether CB should be classified as an ICD, a subsyndromal bipolar disorder (BD), or an obsessive-compulsive disorder (OCD) akin to a hoarding syndrome. To further investigate the appropriate classification of CB, we compared patients with CB, BD, and OCD for impulsivity, affective instability, hoarding, and other OCD symptoms. Eighty outpatients (24 CB, 21 BD, and 35 OCD) who were neither manic nor hypomanic were asked to fill out self-report questionnaires. Compulsive buying patients scored significantly higher on all impulsivity measures and on acquisition but not on the hoarding subdimensions of clutter and "difficulty discarding." Patients with BD scored higher on the mania dimension from the Structured Clinical Interview for Mood Spectrum scale. Patients with OCD scored higher on obsessive-compulsive symptoms and, particularly, higher on the contamination/washing and checking dimensions from the Padua Inventory; however, they did not score higher on any hoarding dimension. A discriminant model built with these variables correctly classified patients with CB (79%), BD (71%), and OCD (77%). Patients with CB came out as impulsive acquirers, resembling ICD- rather than BD- or OCD-related disorders. Manic symptoms were distinctive of patients with BD. Hoarding symptoms other than acquisition were not particularly associated with any diagnostic group. Copyright © 2012 Elsevier Inc. All rights reserved.

    Reduced executive control is one of the central components of model on the development and maintenance of Internet gaming disorder (IGD). Among the various executive control problems, high impulsivity has consistently been associated with IGD. We performed voxel-based morphometric analysis with diffeomorphic anatomical registration by using an exponentiated Lie algebra algorithm (DARTEL) to investigate the relationship of gray matter abnormalities to impulsivity in IGD. Thirty-one young male adults whose excessive Internet gaming began in early adolescence, and 30 age-matched male healthy controls were examined. IGD subjects showed smaller gray matter volume (GMV) in brain regions implicated in executive control, such as the anterior cingulate cortex and the supplementary motor area. The GMVs in the anterior cingulate cortex and the supplementary motor area were negatively correlated with self-reporting scales of impulsiveness. IGD subjects also exhibited smaller GMV in lateral prefrontal and parietal cortices comprising the left ventrolateral prefrontal cortex and the left inferior parietal lobule when compared with healthy controls. The GMVs in the left ventrolateral prefrontal cortex were negatively correlated with lifetime usage of Internet gaming. These findings suggest that gray matter abnormalities in areas related to executive control may contribute to high impulsivity of young adults with IGD. Furthermore, alterations in the prefrontal cortex were related with long-term excessive Internet gaming during adolescence. © 2017 Society for the Study of Addiction.

  10. Association between problematic Internet use and impulse control disorders among Iranian university students.

    Mazhari, Shahrzad

    2012-05-01

    Previous studies have examined the relationship between problematic Internet use (PIU) with pathological gambling and impulsivity. However, few studies have investigated the association between PIU and other impulse control disorders. This study aimed to assess whether PIU is related to compulsive buying, kleptomania, trichotillomania, intermittent explosive disorder, and pyromania, among a sample of Iranian university students. A cross-sectional study design was used among a random sample of (n=950) university students. Self-reported questionnaires, including demographic, Problematic Internet Use Questionnaire (PIUQ) and Minnesota Impulse Disorders Interview were utilized. The prevalence of PIU was 21.2 percent. Students with diagnosis of either compulsive buying, or intermittent explosive disorder, or pyromania had significantly higher scores on PIUQ compared to the students without the diagnosis. Multivariate regression analyses indicated that in the male gender, the diagnosis of either compulsive buying or intermittent explosive disorder were significant predictors of the risk of the PIU. The results support the proposal that PIU should be considered as a spectrum of impulse control disorder.

    Orozco-Cabal, Luis; Rodríguez, Maritza; Herin, David V.; Gempeler, Juanita; Uribe, Miguel

    2010-01-01

    Objective This study determined the validity and reliability of a new, abbreviated version of the Spanish Barratt Impulsiveness Scale (BIS-15S) in Colombian subjects. Method The BIS-15S was tested in non-clinical (n=283) and clinical (n=164) native Spanish-speakers. Intra-scale reliability was calculated using Cronbach’s α, and test-retest reliability was measured with Pearson correlations. Psychometric properties were determined using standard statistics. A factor analysis was performed to determine BIS-15S factor structure. Results 447 subjects participated in the study. Clinical subjects were older and more educated compared to non-clinical subjects. Impulsivity scores were normally distributed in each group. BIS-15S total, motor, non-planning and attention scores were significantly lower in non-clinical vs. clinical subjects. Subjects with substance-related disorders had the highest BIS-15S total scores, followed by subjects with bipolar disorders and bulimia nervosa/binge eating. Internal consistency was 0.793 and test-retest reliability was 0.80. Factor analysis confirmed a three-factor structure (attention, motor, non-planning) accounting for 47.87% of the total variance in BIS-15S total scores. Conclusions The BIS-15S is a valid and reliable self-report measure of impulsivity in this population. Further research is needed to determine additional components of impulsivity not investigated by this measure. PMID:21152412

    There is a paucity of valid, brief instruments for the assessment of lifetime major depressive disorder (MDD) that can be used in, for example, large-scale genomics, imaging or biomarker studies on depression. We developed the LIfetime Depression Assessment Self-report (LIDAS), which assesses lifetime MDD diagnosis according to DSM criteria, and is largely based on the widely used Composite International Diagnostic Interview (CIDI). Here, we tested the feasibility and determined the sensitivity and specificity for measuring lifetime MDD with this new questionnaire, with a regular CIDI as reference. Sensitivity and specificity analyses of the online lifetime MDD questionnaire were performed in adults with (n = 177) and without (n = 87) lifetime MDD according to regular index CIDIs, selected from the Netherlands Study of Depression and Anxiety (NESDA) and Netherlands Twin Register (NTR). Feasibility was tested in an additional non-selective, population-based sample of NTR participants (n = 245). Of the 753 invited persons, 509 (68%) completed the LIDAS, of which 419 (82%) did this online. User-friendliness of the instrument was rated high. Median completion time was 6.2 min. Sensitivity and specificity for lifetime MDD were 85% [95% confidence interval (CI) 80-91%] and 80% (95% CI 72-89%), respectively. This LIDAS instrument gave a lifetime MDD prevalence of 20.8% in the population-based sample. Measuring lifetime MDD with an online instrument was feasible. Sensitivity and specificity were adequate. The instrument gave a prevalence of lifetime MDD in line with reported population prevalences. LIDAS is a promising tool for rapid determination of lifetime MDD status in large samples, such as needed for genomics studies.

  13. Predicting physical health: implicit mental health measures versus self-report scales.

    Cousineau, Tara McKee; Shedler, Jonathan

    2006-06-01

    Researchers have traditionally relied on self-report questionnaires to assess psychological well-being, but such measures may be unable to differentiate individuals who are genuinely psychologically healthy from those who maintain a facade or illusion of mental health based on denial and self-deception. Prior research suggests that clinically derived assessment procedures that assess implicit psychological processes may have advantages over self-report mental health measures. This prospective study compared the Early Memory Index, an implicit measure of mental health/distress, with a range of familiar self-report scales as predictors of physical health. The Early Memory Index showed significant prospective associations with health service utilization and clinically verified illness. In contrast, self-report measures of mental health, perceived stress, life events stress, and mood states did not predict health outcomes. The findings highlight the limitations of self-report questionnaires and suggest that implicit measures have an important role to play in mental health research.

    2001-01-01

    effects. Structural-equation analyses revealed a substantial heritability for self-reported reduced hearing of 40% (95% CI = 19-53%). The remaining variation could be attributed to individuals' nonfamilial environments. CONCLUSION: We found that genetic factors play an important role in self......-reported reduced hearing in both men and women age 70 and older. Because self-reports of reduced hearing involve misclassification, this estimate of the genetic influence on hearing disabilities is probably conservative. Hence, genetic and environmental factors play a substantial role in reduced hearing among......OBJECTIVES: The aim of the present twin study was to estimate the relative importance of genetic and environmental factors in variation in self-reported reduced hearing among the old and the oldest old. DESIGN: Self-reported hearing abilities of older twins assessed at intake interview...

  15. Transgender transitioning and change of self-reported sexual orientation.

    Matthias K Auer

    Full Text Available Sexual orientation is usually considered to be determined in early life and stable in the course of adulthood. In contrast, some transgender individuals report a change in sexual orientation. A common reason for this phenomenon is not known.We included 115 transsexual persons (70 male-to-female "MtF" and 45 female-to-male "FtM" patients from our endocrine outpatient clinic, who completed a questionnaire, retrospectively evaluating the history of their gender transition phase. The questionnaire focused on sexual orientation and recalled time points of changes in sexual orientation in the context of transition. Participants were further asked to provide a personal concept for a potential change in sexual orientation.In total, 32.9% (n = 23 MtF reported a change in sexual orientation in contrast to 22.2% (n = 10 FtM transsexual persons (p = 0.132. Out of these patients, 39.1% (MtF and 60% (FtM reported a change in sexual orientation before having undergone any sex reassignment surgery. FtM that had initially been sexually oriented towards males ( = androphilic, were significantly more likely to report on a change in sexual orientation than gynephilic, analloerotic or bisexual FtM (p = 0.012. Similarly, gynephilic MtF reported a change in sexual orientation more frequently than androphilic, analloerotic or bisexual MtF transsexual persons (p =0.05.In line with earlier reports, we reveal that a change in self-reported sexual orientation is frequent and does not solely occur in the context of particular transition events. Transsexual persons that are attracted by individuals of the opposite biological sex are more likely to change sexual orientation. Qualitative reports suggest that the individual's biography, autogynephilic and autoandrophilic sexual arousal, confusion before and after transitioning, social and self-acceptance, as well as concept of sexual orientation itself may explain this phenomenon.

  16. Do self- reported intentions predict clinicians' behaviour: a systematic review

    Dickinson Heather O

    2006-11-01

    intention was of a similar magnitude to that found in the literature relating to non-health professionals. This was more consistently the case for studies in which intention-behaviour correspondence was good and behaviour was self-reported. Though firm conclusions are limited by a smaller literature, our findings are consistent with that of the non-health professional literature. This review, viewed in the context of the larger populations of studies, provides encouragement for the contention that there is a predictable relationship between the intentions of a health professional and their subsequent behaviour. However, there remain significant methodological challenges.

  17. Burden of Self-reported Acute Gastrointestinal Illness in Cuba

    Prieto, Pablo Aguiar; Finley, Rita L.; Guerin, Michele T.; Isaacs, Sandy; Domínguez, Arnaldo Castro; Marie, Gisele Coutín; Perez, Enrique

    2009-01-01

    Acute gastrointestinal illness is an important public-health issue worldwide. Burden-of-illness studies have not previously been conducted in Cuba. The objective of the study was to determine the magnitude, distribution, and burden of self-reported acute gastrointestinal illness in Cuba. A retrospective, cross-sectional survey was conducted in three sentinel sites during June-July 2005 (rainy season) and during November 2005–January 2006 (dry season). Households were randomly selected from a list maintained by the medical offices in each site. One individual per household was selected to complete a questionnaire in a face-to-face interview. The case definition was three or more bouts of loose stools in a 24-hour period within the last 30 days. In total, 97.3% of 6,576 interviews were completed. The overall prevalence of acute gastrointestinal illness was 10.6%. The risk of acute gastrointestinal illness was higher during the rainy season (odds ratio [OR]=3.85, 95% confidence interval [CI] 3.18-4.66) in children (OR=3.12, 95% CI 2.24-4.36) and teens (OR=2.27, 95% CI 1.51-3.41) compared to people aged 25-54 years, in males (OR=1.24, 95% CI 1.04-1.47), and in the municipality of Santiago de Cuba (OR=1.33, 95% CI 1.11-1.61). Of 680 cases, 17.1-38.1% visited a physician, depending on sentinel site. Of the cases who visited a physician, 33.3-53.9% were requested to submit a stool sample, and of those, 72.7-100.0% complied. Of the cases who sought medical care, 16.7- 61.5% and 0-31.6% were treated with antidiarrhoeals and antibiotics respectively. Acute gastrointestinal illness represented a substantial burden of health compared to developed countries. Targeting the identified risk factors when allocating resources for education, food safety, and infrastructure might lower the morbidity associated with acute gastrointestinal illness. PMID:19507750

  18. Self-Reported Non-Celiac Wheat Sensitivity in High School Students: Demographic and Clinical Characteristics

    Antonio Carroccio

    2017-07-01

    Full Text Available Background: Non-Celiac Wheat Sensitivity (NCWS has recently been included among the gluten-related disorders. As no biomarkers of this disease exist, its frequency has been estimated based on self-reported symptoms, but to date no data are available about self-reported NCWS in teenagers. Aim: To explore the prevalence of self-reported NCWS in a group of high school students and to study their demographic and clinical characteristics. Methods: The study was performed between April 2015 and January 2016 in two high schools of a coastal town in the south of Sicily (Italy. A total of 555 students (mean age 17 years, 191 male, 364 female completed a modified validated questionnaire for self-reported NCWS. The subjects who self-reported NCWS were then compared with all the others. Results: Seven individuals (1.26% had an established diagnosis of CD. The prevalence of self-reported NCWS was 12.2%, and 2.9% were following a gluten-free diet (GFD. Only 15 out of 68 (23% NCWS self-reporters had consulted a doctor for this problem and only nine (14% had undergone serological tests for celiac disease. The NCWS self-reporters very often had IBS symptoms (44%. Conclusions: Self-reported NCWS was found to be common in teenagers, with a frequency of 12.2%; the frequency of GFD use was 2.9%, which was much higher than the percentage of known CD in the same population (1.26%. A greater awareness of the possible implications on the part of the subjects involved, and a more thorough medical approach to the study of self-reported wheat-induced symptoms are required.

    2012-10-15

    The objective of this study was to assess the validity of prevalent and incident self-reported diabetes compared with multiple reference definitions and to assess the reliability (repeatability) of a self-reported diagnosis of diabetes. Data from 10,321 participants in the Atherosclerosis Risk in Communities (ARIC) Study who attended visit 4 (1996-1998) were analyzed. Prevalent self-reported diabetes was compared with reference definitions defined by fasting glucose and medication use obtained at visit 4. Incident self-reported diabetes was assessed during annual follow-up telephone calls and was compared with reference definitions defined by fasting glucose, hemoglobin A1c, and medication use obtained during an in-person visit attended by a subsample of participants (n = 1,738) in 2004-2005. The sensitivity of prevalent self-reported diabetes ranged from 58.5% to 70.8%, and specificity ranged from 95.6% to 96.8%, depending on the reference definition. Similarly, the sensitivity of incident self-reported diabetes ranged from 55.9% to 80.4%, and specificity ranged from 84.5% to 90.6%. Percent positive agreement of self-reported diabetes during 9 years of repeat assessments ranged from 92.7% to 95.4%. Both prevalent self-reported diabetes and incident self-reported diabetes were 84%-97% specific and 55%-80% sensitive as compared with reference definitions using glucose and medication criteria. Self-reported diabetes was >92% reliable over time.

    Addiction is a relapsing chronic condition in which psychiatric phenomena play a crucial role. Psychopathological symptoms in patients with heroin addiction are generally considered to be part of the drug addict's personality, or else to be related to the presence of psychiatric comorbidity, raising doubts about whether patients with long-term abuse of opioids actually possess specific psychopathological dimensions. Using the Self-Report Symptom Inventory (SCL-90), we studied the psychopathological dimensions of 1,055 patients with heroin addiction (884 males and 171 females) aged between 16 and 59 years at the beginning of treatment, and their relationship to age, sex and duration of dependence. A total of 150 (14.2%) patients with heroin addiction showed depressive symptomatology characterised by feelings of worthlessness and being trapped or caught; 257 (24.4%) had somatisation symptoms, 205 (19.4%) interpersonal sensitivity and psychotic symptoms, 235 (22.3%) panic symptomatology, 208 (19.7%) violence and self-aggression. These dimensions were not correlated with sex or duration of dependence. Younger patients with heroin addiction were characterised by higher scores for violence-suicide, sensitivity and panic anxiety symptomatology. Older patients with heroin addiction showed higher scores for somatisation and worthlessness-being trapped symptomatology. This study supports the hypothesis that mood, anxiety and impulse-control dysregulation are the core of the clinical phenomenology of addiction and should be incorporated into its nosology.

    A variety of cognitive and emotional processes influence the decision-making deficits observed in pathological gambling (PG). This study investigated the role of immediate/delayed sensitivity to reward and punishment, executive functions, impulsivity and explicit knowledge in relation to decision-making performance on the original Iowa Gambling Task (IGT-ABCD) and a variant (IGT-EFGH). We assessed 131 consecutive patients with a diagnosis of PG by using executive functioning and decision-making tasks, self-report measures of impulsivity and explicit knowledge. The majority of pathological gamblers (PGs) showed deficits in decision-making, characterized mainly by myopia for the future. Decisions made under risk showed different predictors. Performance on the IGT-ABCD for decisions made under risk was predicted by medium and high levels of explicit knowledge of the task, as well as by scores on the Disorderliness subscale and the degree of Stroop interference. By contrast, IGT-EFGH results were only associated with self-report impulsivity measures. Decision making in PG involves distinct patterns of deficits, and the predictors differ depending on the reinforcement schedule. Decisions made under risk on the IGT-ABCD are associated with explicit knowledge, executive functions and impulsivity traits related to conscious awareness and control processes. On the IGT-EFGH, however, only impulsivity traits predict decision making. Copyright © American Academy of Addiction Psychiatry.

  3. Impulsive behavior and nicotinic acetylcholine receptors.

    Ohmura, Yu; Tsutsui-Kimura, Iku; Yoshioka, Mitsuhiro

    2012-01-01

    Higher impulsivity is thought to be a risk factor for drug addiction, criminal involvement, and suicide. Excessive levels of impulsivity are often observed in several psychiatric disorders including attention-deficit/hyperactivity disorder and schizophrenia. Previous studies have demonstrated that nicotinic acetylcholine receptors (nAChRs) are involved in impulsive behavior. Here, we introduce recent advances in this field and describe the role of the following nAChR-related brain mechanisms in modulating impulsive behavior: dopamine release in the ventral striatum; α4β2 nAChRs in the infralimbic cortex, which is a ventral part of the medial prefrontal cortex (mPFC); and dopamine release in the mPFC. We also suggest several potential therapeutic drugs to address these mechanisms in impulsivity-related disorders and explore future directions to further elucidate the roles of central nAChRs in impulsive behavior.

  4. Evaluating genetic ancestry and self-reported ethnicity in the context of carrier screening.

    2017-11-28

    Current professional society guidelines recommend genetic carrier screening be offered on the basis of ethnicity, or when using expanded carrier screening panels, they recommend to compute residual risk based on ethnicity. We investigated the reliability of self-reported ethnicity in 9138 subjects referred to carrier screening. Self-reported ethnicity gathered from test requisition forms and during post-test genetic counseling, and genetic ancestry predicted by a statistical model, were compared for concordance. We identified several discrepancies between the two sources of self-reported ethnicity and genetic ancestry. Only 30.3% of individuals who indicated Mediterranean ancestry during consultation self-reported this on requisition forms. Additionally, the proportion of individuals who reported Southeast Asian but were estimated to have a different genetic ancestry was found to depend on the source of self-report. Finally, individuals who reported Latin American demonstrated a high degree of ancestral admixture. As a result, carrier rates and residual risks provided for patient decision-making are impacted if using self-reported ethnicity. Our analysis highlights the unreliability of ethnicity classification based on patient self-reports. We recommend the routine use of pan-ethnic carrier screening panels in reproductive medicine. Furthermore, the use of an ancestry model would allow better estimation of carrier rates and residual risks.

  5. Chaotification of complex networks with impulsive control.

    2012-06-01

    This paper investigates the chaotification problem of complex dynamical networks (CDN) with impulsive control. Both the discrete and continuous cases are studied. The method is presented to drive all states of every node in CDN to chaos. The proposed impulsive control strategy is effective for both the originally stable and unstable CDN. The upper bound of the impulse intervals for originally stable networks is derived. Finally, the effectiveness of the theoretical results is verified by numerical examples.

    2013-01-01

    Impulsive differential equations have been developed in modeling impulsive problems in physics, population dynamics, ecology, biotechnology, industrial robotics, pharmacokinetics, optimal control, etc. The questions of existence and stability of solutions for different classes of initial values problems for impulsive differential equations and inclusions with fixed and variable moments are considered in detail. Attention is also given to boundary value problems and relative questions concerning differential equations. This monograph addresses a variety of side issues that arise from its simple

  7. Impulsive synchronization of Chen's hyperchaotic system

    Haeri, Mohammad; Dehghani, Mahsa

    2006-01-01

    In this Letter the impulsive synchronization of the Chen's hyperchaotic systems is discussed. Some new and sufficient conditions on varying impulsive distance are established in order to guarantee the synchronizabillity of the systems using the synchronization method. In particular, some simple conditions are derived in synchronizing the systems by equal impulsive distances. Two illustrative examples are provided to show the feasibility and the effectiveness of the proposed method. The boundaries of the stable regions are also estimated

  8. Correction of self-reported BMI based on objective measurements: a Belgian experience.

    Drieskens, S; Demarest, S; Bel, S; De Ridder, K; Tafforeau, J

    2018-01-01

    Based on successive Health Interview Surveys (HIS), it has been demonstrated that also in Belgium obesity, measured by means of a self-reported body mass index (BMI in kg/m 2 ), is a growing public health problem that needs to be monitored as accurately as possible. Studies have shown that a self-reported BMI can be biased. Consequently, if the aim is to rely on a self-reported BMI, adjustment is recommended. Data on measured and self-reported BMI, derived from the Belgian Food Consumption Survey (FCS) 2014 offers the opportunity to do so. The HIS and FCS are cross-sectional surveys based on representative population samples. This study focused on adults aged 18-64 years (sample HIS = 6545 and FCS = 1213). Measured and self-reported BMI collected in FCS were used to assess possible misreporting. Using FCS data, correction factors (measured BMI/self-reported BMI) were calculated in function of a combination of background variables (region, gender, educational level and age group). Individual self-reported BMI of the HIS 2013 were then multiplied with the corresponding correction factors to produce a corrected BMI-classification. When compared with the measured BMI, the self-reported BMI in the FCS was underestimated (mean 0.97 kg/m 2 ). 28% of the obese people underestimated their BMI. After applying the correction factors, the prevalence of obesity based on HIS data significantly increased (from 13% based on the original HIS data to 17% based on the corrected HIS data) and approximated the measured one derived from the FCS data. Since self-reported calculations of BMI are underestimated, it is recommended to adjust them to obtain accurate estimates which are important for decision making.

  9. Impaired decisional impulsivity in pathological videogamers.

    Michael A Irvine

    Full Text Available Pathological gaming is an emerging and poorly understood problem. Impulsivity is commonly impaired in disorders of behavioural and substance addiction, hence we sought to systematically investigate the different subtypes of decisional and motor impulsivity in a well-defined pathological gaming cohort.Fifty-two pathological gaming subjects and age-, gender- and IQ-matched healthy volunteers were tested on decisional impulsivity (Information Sampling Task testing reflection impulsivity and delay discounting questionnaire testing impulsive choice, and motor impulsivity (Stop Signal Task testing motor response inhibition, and the premature responding task. We used stringent diagnostic criteria highlighting functional impairment.In the Information Sampling Task, pathological gaming participants sampled less evidence prior to making a decision and scored fewer points compared with healthy volunteers. Gaming severity was also negatively correlated with evidence gathered and positively correlated with sampling error and points acquired. In the delay discounting task, pathological gamers made more impulsive choices, preferring smaller immediate over larger delayed rewards. Pathological gamers made more premature responses related to comorbid nicotine use. Greater number of hours played also correlated with a Motivational Index. Greater frequency of role playing games was associated with impaired motor response inhibition and strategy games with faster Go reaction time.We show that pathological gaming is associated with impaired decisional impulsivity with negative consequences in task performance. Decisional impulsivity may be a potential target in therapeutic management.

  10. The relationship between students' self-reported aggressive communication and motives to communicate with their instructors.

    Edwards, Chad; Myers, Scott A

    Using a convenience sample, 172 college students' (M age = 20.2 yr., SD = 2.5) motives for communicating with their instructors and their own verbal aggressiveness and argumentativeness were studied using the Argumentativeness Scale, the Verbal Aggressiveness Scale, and the Student Motives to Communicate Scale. Significant negative relationships were obtained between students' self-reports of argumentativeness and the sycophantic motive and between students' self-reports of verbal aggressiveness and the functional motive, but generally, students' motives to communicate with their instructors generally were not associated with their self-reported aggressive communication behaviors.

  11. An empirical examination of self-reported work stress among U.S. managers.

    Cavanaugh, M A; Boswell, W R; Roehling, M V; Boudreau, J W

    2000-02-01

    This study proposes that self-reported work stress among U.S. managers is differentially related (positively and negatively) to work outcomes depending on the stressors that are being evaluated. Specific hypotheses were derived from this general proposition and tested using a sample of 1,886 U.S. managers and longitudinal data. Regression results indicate that challenge-related self-reported stress is positively related to job satisfaction and negatively related to job search. In contrast, hindrance-related self-reported stress is negatively related to job satisfaction and positively related to job search and turnover. Future research directions are discussed.

  13. Assessing dependency using self-report and indirect measures: examining the significance of discrepancies.

    Cogswell, Alex; Alloy, Lauren B; Karpinski, Andrew; Grant, David A

    2010-07-01

    The present study addressed convergence between self-report and indirect approaches to assessing dependency. We were moderately successful in validating an implicit measure, which was found to be reliable, orthogonal to 2 self-report instruments, and predictive of external criteria. This study also examined discrepancies between scores on self-report and implicit measures, and has implications for their significance. The possibility that discrepancies themselves are pathological was not supported, although discrepancies were associated with particular personality profiles. Finally, this study offered additional evidence for the relation between dependency and depressive symptomatology and identified implicit dependency as contributing unique variance in predicting past major depression.

  14. Family routine moderates the relation between child impulsivity and oppositional defiant disorder symptoms.

    Lanza, H Isabella; Drabick, Deborah A G

    2011-01-01

    Although child impulsivity is associated with oppositional defiant disorder (ODD) symptoms, few studies have examined whether family processes moderate this association. To address this gap, we tested whether child-reported family routine moderated the relation between child hyperactivity/impulsivity (HI) and ODD symptoms among a sample of low-income, urban, ethnic-minority children (N = 87, 51% male). Child HI and ODD symptoms were assessed using parent and teacher reports. HI also was indexed by a laboratory task. Family routine was assessed using child self-report. Hierarchical regression analyses indicated that family routine moderated child HI. Among children with higher levels of teacher-reported HI symptoms, lower levels of family routine were associated with higher levels of teacher-reported ODD symptoms compared to children with lower levels of teacher-reported HI symptoms. Children who self-reported higher levels of family routine were rated as low on teacher-reported ODD symptoms, regardless of teacher-reported HI levels. Parent report and laboratory measures of child HI did not produce significant interactions. Lower levels of family routine may confer risk for ODD symptoms among low-income, urban, ethnic-minority children experiencing higher levels of HI.

    2013-01-01

    Before it is possible to test whether men and women differ in impulsivity, it is necessary to evaluate whether impulsivity measures are invariant across sex. The UPPS-P Impulsive Behavior Scale (negative urgency, lack of premeditation, lack of perseverance, and sensation seeking, with added subscale of positive urgency) is one measure of five…

  17. Impulse approximation in solid helium

    Glyde, H.R.

    1985-01-01

    The incoherent dynamic form factor S/sub i/(Q, ω) is evaluated in solid helium for comparison with the impulse approximation (IA). The purpose is to determine the Q values for which the IA is valid for systems such a helium where the atoms interact via a potential having a steeply repulsive but not infinite hard core. For 3 He, S/sub i/(Q, ω) is evaluated from first principles, beginning with the pair potential. The density of states g(ω) is evaluated using the self-consistent phonon theory and S/sub i/(Q,ω) is expressed in terms of g(ω). For solid 4 He resonable models of g(ω) using observed input parameters are used to evaluate S/sub i/(Q,ω). In both cases S/sub i/(Q, ω) is found to approach the impulse approximation S/sub IA/(Q, ω) closely for wave vector transfers Q> or approx. =20 A -1 . The difference between S/sub i/ and S/sub IA/, which is due to final state interactions of the scattering atom with the remainder of the atoms in the solid, is also predominantly antisymmetric in (ω-ω/sub R/), where ω/sub R/ is the recoil frequency. This suggests that the symmetrization procedure proposed by Sears to eliminate final state contributions should work well in solid helium

  20. Phenotypic, genetic, and environmental relationships between self-reported talents and measured intelligence.

    Schermer, Julie Aitken; Johnson, Andrew M; Jang, Kerry L; Vernon, Philip A

    2015-02-01

    The relationship between self-report abilities and measured intelligence was examined at both the phenotypic (zero-order) level as well as at the genetic and environmental levels. Twins and siblings (N = 516) completed a timed intelligence test and a self-report ability questionnaire, which has previously been found to produce 10 factors, including: politics, interpersonal relationships, practical tasks, intellectual pursuits, academic skills, entrepreneur/business, domestic skills, vocal abilities, and creativity. At the phenotypic level, the correlations between the ability factor scores and intelligence ranged from 0.01 to 0.42 (between self-report academic abilities and verbal intelligence). Further analyses found that some of the phenotypic relationships between self-report ability scores and measured intelligence also had significant correlations at the genetic and environmental levels, suggesting that some of the observed relationships may be due to common genetic and/or environmental factors.

    This study examined associations between college students' self-report and measured height and weight. Participants (N = 1,686) were 77% white, 62% female, aged 18-24 years (mean ± SD, 19.1 ± 1.1 years), and enrolled at 8 US universities. Body mass index (BMI) was calculated for self-report (via online survey); trained researchers measured height and weight and categorized them as normal (18.5 to obese (30 to obese (≥ 35). Concordance of self-report vs objectively measured BMI groups using chi-square revealed that 93% were accurate, 4% were underestimated, and 2.7% were overestimated. Pearson correlations and adjusted linear regression revealed significant associations between self-report and measured BMI (r = .97; P students.

  3. Does social desirability compromise self-reports of physical activity in web-based research?

    Göritz Anja S

    2011-04-01

    Full Text Available Abstract Background This study investigated the relation between social desirability and self-reported physical activity in web-based research. Findings A longitudinal study (N = 5,495, 54% women was conducted on a representative sample of the Dutch population using the Marlowe-Crowne Scale as social desirability measure and the short form of the International Physical Activity Questionnaire. Social desirability was not associated with self-reported physical activity (in MET-minutes/week, nor with its sub-behaviors (i.e., walking, moderate-intensity activity, vigorous-intensity activity, and sedentary behavior. Socio-demographics (i.e., age, sex, income, and education did not moderate the effect of social desirability on self-reported physical activity and its sub-behaviors. Conclusions This study does not throw doubt on the usefulness of the Internet as a medium to collect self-reports on physical activity.

  4. Self-reported versus behavioral self-handicapping: empirical evidence for a theoretical distinction.

    Hirt, E R; Deppe, R K; Gordon, L J

    1991-12-01

    The present study was an investigation of how Ss would respond when given 2 self-handicapping options, 1 behavioral (withdrawal of practice effort) and 1 self-reported (reporting high levels of stress). Ss anticipating a diagnostic test of intellectual ability were given different instructions regarding the effects of stress and practice on test performance. Ss were told that (a) stress only, (b) practice only, (c) both stress and practice, or (d) neither stress nor practice affected test scores. Ss were then given the opportunity to self-report a handicap on a stress inventory and to behaviorally self-handicap by failing to practice before the test. High self-handicapping men and women showed evidence of self-reported handicapping, but only high self-handicapping men behaviorally self-handicapped. However, when both self-handicaps were viable, both high self-handicapping men and women preferred the self-reported over the behavioral self-handicap.

    Kristoffersen, Espen Saxhaug; Aaseth, Kjersti; Grande, Ragnhild Berling; Lundqvist, Christofer; Russell, Michael Bjørn

    2013-04-18

    Chronic headache is associated with disability and high utilisation of health care including complementary and alternative medicine (CAM). We investigated self-reported efficacy of CAM in people with chronic headache from the general population. Respondents with possible self-reported chronic headache were interviewed by physicians experienced in headache diagnostics. CAM queried included acupuncture, chiropractic, homeopathy, naprapathy, physiotherapy, psychological treatment, and psychomotor physiotherapy. Sixty-two % and 73% of those with primary and secondary chronic headache had used CAM.Self-reported efficacy of CAM ranged from 0-43% without significant differences between gender, headache diagnoses, co-occurrence of migraine, medication use or physician contact. CAM is widely used, despite self-reported efficacy of different CAM modalities is modest in the management of chronic headache.

  7. An initial look at sibling reports on children's behavior: comparisons with children's self-reports and relations with siblings' self-reports and sibling relationships.

    Epkins, C C; Dedmon, A M

    1999-10-01

    The authors examined siblings' reports of children's depression, anxiety, and aggression, and their reports of the sibling relationship, and compared them with children's self-reports. In two samples, including 169 sibling pairs (age M = 9.98 years, SD = 1.51), no significant differences emerged in the levels of depression and anxiety found in siblings' reports of children's behavior and children's self-reports, although siblings reported children to have significantly higher levels of aggression than the children self-reported. Age, the difference in ages between siblings, sex, and sibling sex were not related to siblings' reports of children's behavior. The relations between children's and siblings' reports of children's behavior were significant, yet moderate (average r = .22). Both siblings' self-reports of internalizing behavior and their perceptions of aspects of the sibling relationship (affection, rivalry, hostility, and satisfaction with the sibling relationship) explained significant, and unique, variance in siblings' reports of children's internalizing behavior. The findings for aggressive behavior were similar, although siblings' perceptions of affection in the sibling relationship were not significantly related to their reports of children's aggression. The potential uses and benefits of sibling reports of children's behavior, and sibling and family relationships, are discussed.

  8. Validity of self-reported weight and height: a cross-sectional study among Malaysian adolescents

    C. C. Kee

    2017-06-01

    Full Text Available Abstract Background Self-reported weight and height are commonly used in lieu of direct measurements of weight and height in large epidemiological surveys due to inevitable constraints such as budget and human resource. However, the validity of self-reported weight and height, particularly among adolescents, needs to be verified as misreporting could lead to misclassification of body mass index and therefore overestimation or underestimation of the burden of BMI-related diseases. The objective of this study was to determine the validity of self-reported weight and height among Malaysian secondary school children. Methods Both self-reported and directly measured weight and height of a subgroup of 663 apparently healthy schoolchildren from the Malaysian Adolescent Health Risk Behaviour (MyAHRB survey 2013/2014 were analysed. Respondents were required to report their current body weight and height via a self-administrative questionnaire before they were measured by investigators. The validity of self-reported against directly measured weight and height was examined using intraclass correlation coefficient (ICC, the Bland-Altman plot and weighted Kappa statistics. Results There was very good intraclass correlation between self-reported and directly measured weight [r = 0.96, 95% confidence interval (CI: 0.93, 0.97] and height (r = 0.94, 95% CI: 0.90, 0.96. In addition the Bland-Altman plots indicated that the mean difference between self-reported and direct measurement was relatively small. The mean difference (self-reported minus direct measurements was, for boys: weight, −2.1 kg; height, −1.6 cm; BMI, −0.44 kg/m2 and girls: weight, −1.2 kg; height, −0.9 cm; BMI, −0.3 kg/m2. However, 95% limits of agreement were wide which indicated substantial discrepancies between self-reported and direct measurements method at the individual level. Nonetheless, the weighted Kappa statistics demonstrated a substantial agreement between BMI

  10. Impulsivity in binge eating disorder: food cues elicit increased reward responses and disinhibition.

    Kathrin Schag

    Full Text Available BACKGROUND: Binge eating disorder (BED represents a distinct eating disorder diagnosis. Current approaches assume increased impulsivity to be one factor leading to binge eating and weight gain. We used eye tracking to investigate both components of impulsivity, namely reward sensitivity and rash-spontaneous behaviour towards food in BED for the first time. METHODS: Overweight and obese people with BED (BED+; n = 25, without BED (BED-; n = 26 and healthy normal-weight controls (NWC; n = 25 performed a free exploration paradigm measuring reward sensitivity (experiment 1 and a modified antisaccade paradigm measuring disinhibited, rash-spontaneous behaviour (experiment 2 using food and nonfood stimuli. Additionally, trait impulsivity was assessed. RESULTS: In experiment 1, all participants located their initial fixations more often on food stimuli and BED+ participants gazed longer on food stimuli in comparison with BED- and NWC participants. In experiment 2, BED+ participants had more difficulties inhibiting saccades towards food and nonfood stimuli compared with both other groups in first saccades, and especially towards food stimuli in second saccades and concerning sequences of first and second saccades. BED- participants did not differ significantly from NWC participants in both experiments. Additionally, eye tracking performance was associated with self-reported reward responsiveness and self-control. CONCLUSIONS: According to these results, food-related reward sensitivity and rash-spontaneous behaviour, as the two components of impulsivity, are increased in BED in comparison with weight-matched and normal-weight controls. This indicates that BED represents a neurobehavioural phenotype of obesity that is characterised by increased impulsivity. Interventions for BED should target these special needs of affected patients.

  13. Development and validation of a self-reported periodontal disease measure among Jordanians.

    Khader, Yousef; Alhabashneh, Rola; Alhersh, Fadi

    2015-08-01

    The development of self-reported measures of periodontal disease would be of great benefit to facilitate epidemiological studies of periodontal disease on a larger scale, and to allow for surveillance of the periodontal condition of populations over time. To develop a culturally adapted self-reported measure of periodontal disease, test its predictive and discriminative validity and establish a cut-off value for this measure to diagnose periodontal disease. A total of 288 Jordanian adults completed the questionnaire assessing self-reported periodontal health (18 questions) and underwent periodontal examination. Of the 18 questions, six were significantly associated with at least one clinical definition of periodontitis and were used to constitute the self-reported periodontal disease measure. Receiver-operating characteristics (ROC) curve analyses were used to examine the overall discriminatory power, sensitivity and specificity, and corresponding cut-off points of the self-reported periodontal disease measure. ROC analysis showed that the self-reported periodontal disease measure had an excellent performance to discriminate between those with and without periodontal disease, regardless of the clinical definition used. A score of 2, on a scale of 0 to 6, had the highest sensitivity and specificity to detect periodontal disease when defined by all study criteria. Significant associations were observed between self-reported periodontal disease measures and all clinical definitions in the regression analysis (the odds ratio ranged from 8.31 to 18.96), according to the clinical definition to be predicted. Self-reported periodontal disease measures have excellent predictive and discriminative validity when tested against clinical definitions, and severity and extent of periodontal disease. © 2015 FDI World Dental Federation.

  18. Comparing the Self-Report and Measured Smartphone Usage of College Students: A Pilot Study.

    Lee, Heyoung; Ahn, Heejune; Nguyen, Trung Giang; Choi, Sam-Wook; Kim, Dae Jin

    2017-03-01

    Nowadays smartphone overuse has become a social and medical concern. For the diagnosis and treatment, clinicians use the self-report information, but the report data often does not match actual usage pattern. The paper examines the similarity and variance in smartphone usage patterns between the measured data and self-reported data. Together with the self-reported data, the real usage log data is collected from 35 college students in a metropolitan region of Northeast Asia, using Android smartphone monitoring application developed by the authors. The unconscious users underestimate their usage time by 40%, in spite of 15% more use in the actual usage. Messengers are most-used application regardless of their self-report, and significant preference to SNS applications was observed in addict group. The actual hourly pattern is consistent with the reported one. College students use more in the afternoon, when they have more free time and cannot use PCs. No significant difference in hourly pattern is observed between the measured and self-report. The result shows there are significant cognitive bias in actual usage patterns exists in self report of smartphone addictions. Clinicians are recommended to utilize measurement tools in diagnosis and treatment of smartphone overusing subjects.

  19. Fear of crime and its relationship to self-reported health and stress among men.

    2017-12-13

    Fear of crime is a growing social and public health problem globally, including in developed countries such as Sweden. This study investigated the impact of fear of crime on self-reported health and stress among men living in Gävleborg County. The study used data collected from 2993 men through a cross sectional survey in the 2014 Health in Equal Terms survey. Descriptive and logistic regression analyses were carried out to study the relationship between fear of crime and self-reported health and stress. There was a statistically significant association between fear of crime and self-reported poor health and stress among men residing in Gävleborg County. In the bivariate analysis, men who reported fear of crime had odds of 1.98 (CI 1.47-2.66) and 2.23 (CI 1.45-3.41) respectively. Adjusting for demographic, social and economic variables in the multivariate analysis only reduced the odds ratio for self-reported poor health to 1.52 (CI 1.05-2.21) but not for self-reported stress with odds of 2.22 (1.27-3.86). Fear of crime among men was statistically significantly associated with self-reported poor health and stress in Gävleborg County. However, the statistically significant relationship remained even after accounting for demographic, social and economic factors, which warrants further research to better understand the role played by other variables.

  20. The agreement between self-reported cervical smear abnormalities and screening programme records.

    Canfell, Karen; Beral, Valerie; Green, Jane; Cameron, Rebecca; Baker, Krys; Brown, Anna

    2006-01-01

    The Million Women Study is a cohort study of women aged 50-64 years in England and Scotland. As a component of the follow-up questionnaire, participants were asked to indicate if they had an abnormal cervical smear in the previous five years. This study compared self-reported cervical abnormalities with screening records obtained from the National Health Service Cervical Screening Programme. For 1944 randomly selected Million Women Study participants in Oxfordshire, screening records were assessed over a six-year period prior to the date of self-reporting. The six-year period was chosen to allow for errors in the recall of timing of abnormal smears. A total of 68 women (3.5%) had a record of at least one equivocal or abnormal smear within the last six years, whereas 49 women (2.5%) self-reported an abnormality. There was a strong trend for an increased probability of self-reporting a history of an abnormal smear as the severity of the recorded abnormality increased (P screening programme records show an abnormal smear, the proportion self-reporting an abnormality increases with the severity of the recorded lesion. Almost all women with a record of negative or inadequate smear(s) correctly interpret the result and do not self-report an abnormality.

  1. Self-report measures of prospective memory are reliable but not valid.

    Uttl, Bob; Kibreab, Mekale

    2011-03-01

    Are self-report measures of prospective memory (ProM) reliable and valid? To examine this question, 240 undergraduate student volunteers completed several widely used self-report measures of ProM including the Prospective Memory Questionnaire (PMQ), the Prospective and Retrospective Memory Questionnaire (PRMQ), the Comprehensive Assessment of Prospective Memory (CAPM) questionnaire, self-reports of retrospective memory (RetM), objective measures of ProM and RetM, and measures of involvement in activities and events, memory strategies and aids use, personality and verbal intelligence. The results showed that both convergent and divergent validity of ProM self-reports are poor, even though we assessed ProM using a newly developed, reliable continuous measure. Further analyses showed that a substantial proportion of variability in ProM self-report scores was due to verbal intelligence, personality (conscientiousness, neuroticism), activities and event involvement (busyness), and use of memory strategies and aids.

    Khadr, Zeinab; Yount, Kathryn

    2012-09-01

    This study explores the reasons for gender differences in self-reported physical limitation among older adults in Ismailia, Egypt. 435 women and 448 men, 50 years and older in Ismailia, Egypt, participated in a social survey and tests of physical performance. Ordered logit models were estimated to compare unadjusted gender differences in reported disability with these differences adjusted sequentially for (a) age and objective measures of physical performance, (b) self-reported morbidities and health care use, and (c) social and economic attributes. Compared with men, women more often reported higher levels of limitation in activities of daily living (ADLs), upper-extremity range of motion (ROM), and lower-extremity gross mobility (GM). Adjusting for age and objective measures of physical performance, women and men had similar odds of self-reporting difficulty with ADLs. With sequential adjustments for the remaining variables, women maintained significantly higher odds of self-reported difficulty with upper-extremity ROM and lower-extremity GM. Cross-culturally, gender differences in self-reported disability may arise from objective and subjective perceptions of disability. Collectively, these results and those from prior studies in Bangladesh and the United States suggest that gender gaps in self-reported physical limitation may be associated with the degree of gender equality in society.

  3. The reliability, validity, and accuracy of self-reported absenteeism from work: a meta-analysis.

    Johns, Gary; Miraglia, Mariella

    2015-01-01

    Because of a variety of access limitations, self-reported absenteeism from work is often employed in research concerning health, organizational behavior, and economics, and it is ubiquitous in large scale population surveys in these domains. Several well established cognitive and social-motivational biases suggest that self-reports of absence will exhibit convergent validity with records-based measures but that people will tend to underreport the behavior. We used meta-analysis to summarize the reliability, validity, and accuracy of absence self-reports. The results suggested that self-reports of absenteeism offer adequate test-retest reliability and that they exhibit reasonably good rank order convergence with organizational records. However, people have a decided tendency to underreport their absenteeism, although such underreporting has decreased over time. Also, self-reports were more accurate when sickness absence rather than absence for any reason was probed. It is concluded that self-reported absenteeism might serve as a valid measure in some correlational research designs. However, when accurate knowledge of absolute absenteeism levels is essential, the tendency to underreport could result in flawed policy decisions.

  4. Impulsive stabilization and impulsive synchronization of discrete-time delayed neural networks.

    Chen, Wu-Hua; Lu, Xiaomei; Zheng, Wei Xing

    2015-04-01

    This paper investigates the problems of impulsive stabilization and impulsive synchronization of discrete-time delayed neural networks (DDNNs). Two types of DDNNs with stabilizing impulses are studied. By introducing the time-varying Lyapunov functional to capture the dynamical characteristics of discrete-time impulsive delayed neural networks (DIDNNs) and by using a convex combination technique, new exponential stability criteria are derived in terms of linear matrix inequalities. The stability criteria for DIDNNs are independent of the size of time delay but rely on the lengths of impulsive intervals. With the newly obtained stability results, sufficient conditions on the existence of linear-state feedback impulsive controllers are derived. Moreover, a novel impulsive synchronization scheme for two identical DDNNs is proposed. The novel impulsive synchronization scheme allows synchronizing two identical DDNNs with unknown delays. Simulation results are given to validate the effectiveness of the proposed criteria of impulsive stabilization and impulsive synchronization of DDNNs. Finally, an application of the obtained impulsive synchronization result for two identical chaotic DDNNs to a secure communication scheme is presented.

    Agarwal, Ravi; O'Regan, Donal

    2017-01-01

    This monograph is the first published book devoted to the theory of differential equations with non-instantaneous impulses. It aims to equip the reader with mathematical models and theory behind real life processes in physics, biology, population dynamics, ecology and pharmacokinetics. The authors examine a wide scope of differential equations with non-instantaneous impulses through three comprehensive chapters, providing an all-rounded and unique presentation on the topic, including: - Ordinary differential equations with non-instantaneous impulses (scalar and n-dimensional case) - Fractional differential equa tions with non-instantaneous impulses (with Caputo fractional derivatives of order q ϵ (0, 1)) - Ordinary differential equations with non-instantaneous impulses occurring at random moments (with exponential, Erlang, or Gamma distribution) Each chapter focuses on theory, proofs and examples, and contains numerous graphs to enrich the reader’s understanding.

  8. Destabilizing Effects of Impulse in Delayed Bam Neural Networks

    Li, Chuandong; Li, Chaojie; Liu, Chao

    This paper further studies the global exponential stability of the equilibrium point of the delayed bidirectional associative memory (DBAM) neural networks with impulse effects. Several results characterizing the aggregated effects of impulse and dynamical property of the impulse-free DBAM on the exponential stability of the considered DBAM have been established. It is shown that the impulsive DBAM will preserve the global exponential stability of the impulse-free DBAM even if the impulses have enlarging effects on the states of neurons.

  9. [Neurochemistry of impulsiveness and aggression].

    Vetulani, Jerzy

    2013-01-01

    Aggression is the most frequent social reaction among animals and men, and plays an important role in survival of the fittest. The change of social conditions in the course of development of human civilisation rendered some forms of aggression counter-adaptive, but the neurobiological mechanism of expression of aggression have not fundamentally changed in the last stages of human evolution. The two different kinds of aggression: emotional, serving mainly as a threat, and rational, predatory, serving for the attainment of goal in the most effective way, have different anatomical and neurobiological background and reciprocally inhibit each other. Aggression is modulated by several neurotransmitter and hormonal systems, of which the key role is seemingly played by testosterone, a hormone involved in domination behaviour, and serotonin, whose deficit results in increased impulsiveness.

  10. Trait impulsivity predicts D-KEFS tower test performance in university students.

    Lyvers, Michael; Basch, Vanessa; Duff, Helen; Edwards, Mark S

    2015-01-01

    The present study examined a widely used self-report index of trait impulsiveness in relation to performance on a well-known neuropsychological executive function test in 70 university undergraduate students (50 women, 20 men) aged 18 to 24 years old. Participants completed the Barratt Impulsiveness Scale (BIS-11) and the Frontal Systems Behavior Scale (FrSBe), after which they performed the Tower Test of the Delis-Kaplan Executive Function System. Hierarchical linear regression showed that after controlling for gender, current alcohol consumption, age at onset of weekly alcohol use, and FrSBe scores, BIS-11 significantly predicted Tower Test Achievement scores, β = -.44, p impulsiveness is associated with poorer executive cognitive performance even in a sample likely to be characterized by relatively high general cognitive functioning (i.e., university students). The results also support the role of inhibition as a key aspect of executive task performance. Elevated scores on the BIS-11 and FrSBe are known to be linked to risky drinking in young adults as confirmed in this sample; however, only BIS-11 predicted Tower Test performance.

  11. Self-reported versus informant-reported depressive symptoms in adults with mild intellectual disability.

    Mileviciute, I; Hartley, S L

    2015-02-01

    Virtually nothing is known about potential differences in the types of depression symptoms reported by adults with mild intellectual disability (ID) on self-reported questionnaires as compared with the types of symptoms reported by caregivers on informant questionnaires. Moreover, little is known about how the presentation of depression among adults with mild ID varies based on socio-demographic characteristics. We compared findings from two self-reported questionnaires, the Self-Reported Depression Questionnaire (SRDQ) and the Glasgow Depression Scale for People with a Learning Disability (GDS), to that of an informant questionnaire of depressive symptoms, the Glasgow Depression Scale--Caregiver Supplement (CGDS), in 80 adults with mild ID. We also examined the association between age, sex, IQ and the presence of a co-occurring psychiatric disorder and frequency of affective, cognitive and somatic depressive symptoms in our sample of adults with mild ID. Adults with mild ID self-reported a higher frequency of affective and cognitive depressive symptoms than staff reported on the informant measure. Staff reported a higher frequency of somatic symptoms than adults with mild ID on one of the self-reported questionnaires (GDS) and a similar frequency on the other self-reported questionnaire (SRDQ). Important differences were found in the types of depressive symptoms based on their IQ, age and presence of a co-occurring psychiatric disorder. Informant questionnaires offer valuable information, but assessment should include self-reported questionnaires as these questionnaires add unique information about internalised experiences (affective and cognitive symptoms) of adults with mild ID that may not be apparent to caregivers. Health care providers should be made aware of the important differences in the presentation of depressive based on their IQ, age and presence of a co-occurring psychiatric disorder. © 2013 John Wiley & Sons Ltd, MENCAP & IASSID.

  12. Relations Between Self-Reported and Linguistic Monitoring Assessments of Affective Experience in an Extreme Environment.

    Smith, Nathan

    2018-03-01

    Approaches for monitoring psychosocial health in challenging environments are needed to maintain the performance and safety of personnel. The purpose of the present research was to examine the relationship between 2 candidate methods (self-reported and linguistics) for monitoring affective experience during extreme environment activities. A single-subject repeated-measures design was used in the present work. The participant was a 46-year-old individual scheduled to complete a self-supported ski expedition across Arctic Greenland. The expedition lasted 28 days, and conditions included severe cold, low stimulation, whiteouts, limited habitability, and threats to life and limb. During the expedition, the participant completed a daily self-report log including assessment of psychological health (perceptions of control and affect) and a video diary (emotion). Video diary entries were subjected to linguistic inquiry and word count analyses before the links between self-report and linguistic data across the expedition period were tested. Similarities in the pattern of self-reported and linguistic assessments emerged across the expedition period. A number of predictable correlations were identified between self-reported and linguistic assessments of affective/emotional experience. Overall, there was better agreement between self-reports and linguistic analytics for indicators of negative affect/emotion. Future research should build on this initial study to further test the links between self-reported affect and emotional states monitored via linguistics. This could help develop methods for monitoring psychological health in extreme environments and support organizational decision making. Crown Copyright © 2017. Published by Elsevier Inc.

  13. Validity of self-reported sleep bruxism among myofascial temporomandibular disorder patients and controls.

    2015-10-01

    Sleep bruxism (SB), primarily involving rhythmic grinding of the teeth during sleep, has been advanced as a causal or maintenance factor for a variety of oro-facial problems, including temporomandibular disorders (TMD). As laboratory polysomnographic (PSG) assessment is extremely expensive and time-consuming, most research testing this belief has relied on patient self-report of SB. The current case-control study examined the accuracy of those self-reports relative to laboratory-based PSG assessment of SB in a large sample of women suffering from chronic myofascial TMD (n = 124) and a demographically matched control group without TMD (n = 46). A clinical research coordinator administered a structured questionnaire to assess self-reported SB. Participants then spent two consecutive nights in a sleep laboratory. Audiovisual and electromyographic data from the second night were scored to assess whether participants met criteria for the presence of 2 or more (2+) rhythmic masticatory muscle activity episodes accompanied by grinding sounds, moderate SB, or severe SB, using previously validated research scoring standards. Contingency tables were constructed to assess positive and negative predictive values, sensitivity and specificity, and 95% confidence intervals surrounding the point estimates. Results showed that self-report significantly predicted 2+ grinding sounds during sleep for TMD cases. However, self-reported SB failed to significantly predict the presence or absence of either moderate or severe SB as assessed by PSG, for both cases and controls. These data show that self-report of tooth grinding awareness is highly unlikely to be a valid indicator of true SB. Studies relying on self-report to assess SB must be viewed with extreme caution. © 2015 John Wiley & Sons Ltd.

  14. Impact of Androgen Deprivation Therapy on Self-Reported Cognitive Function in Men with Prostate Cancer.

    2018-03-01

    Although androgen deprivation therapy is widely used to treat prostate cancer, its effects on cognitive function are unclear. To our knowledge no prior report has examined the impact of androgen deprivation therapy on self-reported cognitive function. Three groups of men 50 years old or older who were matched on age and education were enrolled in the study, including 81 with prostate cancer starting on continuous androgen deprivation therapy, 84 controls with prostate cancer not receiving androgen deprivation therapy and 85 healthy controls. Two scales from the FACT-Cog (Functional Assessment of Cancer Therapy-Cognitive subscale) version 3 were used to assess self-reported cognitive function. Changes in cognitive scores with time were analyzed by 2 approaches, including 1) multivariable regression and 2) calculation of the proportion of subjects per group with a decrease of 1 SD or more. Multivariable regression was applied to assess predictors of a decline in self-reported cognitive function. We also examined relationships between the FACT-Cog and a neuropsychological battery of 15 tests. Mean participant age was 69 years (range 50 to 87). The mean educational level was 15 years (range 8 to 24). FACT-Cog scores were similar at baseline across the cohorts. Neither analytical approach revealed that androgen deprivation therapy was associated with changes in self-reported cognitive function on either FACT-Cog scale. Mood and fatigue correlated with changes in self-reported cognitive function. The relationship between self-reported and objective cognitive measures was weak (maximum Spearman correlation coefficient 0.14) and only 2 of 30 correlations were statistically significant. A total of 12 months of androgen deprivation therapy were not associated with self-reported cognitive function changes in older men with nonmetastatic prostate cancer.

  15. Correlation Between Acoustic Measurements and Self-Reported Voice Disorders Among Female Teachers.

    Lin, Feng-Chuan; Chen, Sheng Hwa; Chen, Su-Chiu; Wang, Chi-Te; Kuo, Yu-Ching

    2016-07-01

    Many studies focused on teachers' voice problems and most of them were conducted using questionnaires, whereas little research has investigated the relationship between self-reported voice disorders and objective quantification of voice. This study intends to explore the relationship of acoustic measurements according to self-reported symptoms and its predictive value of future dysphonia. This is a case-control study. Voice samples of 80 female teachers were analyzed, including 40 self-reported voice disorders (VD) and 40 self-reported normal voice (NVD) subjects. The acoustic measurements included jitter, shimmer, and noise-to-harmonics ratio (NHR). Levene's t test and logistic regression were used to analyze the differences between VD and NVD and the relationship between self-reported voice conditions and the acoustic measurements. To examine whether acoustic measurements can be used to predict further voice disorders, we applied a receiver operating characteristic (ROC) curve to determine the cutoff values and the associated sensitivity and specificity. The results showed that jitter, shimmer, and the NHR of VD were significantly higher than those of NVD. Among the parameters, the NHR and shimmer demonstrated the highest correlation with self-reported voice disorders. By using the NHR ≥0.138 and shimmer ≥0.470 dB as the cutoff values, the ROC curve displayed 72.5% of sensitivity and 75% of specificity, and the overall positive predictive value for subsequent dysphonia achieved 60%. This study demonstrated a significant correlation between acoustic measurements and self-reported dysphonic symptoms. NHR and ShdB are two acoustic parameters that are more able to reflect vocal abnormalities and, probably, to predict subsequent subjective voice disorder. Future research recruiting more subjects in other occupations and genders shall validate the preliminary results revealed in this study. Copyright © 2016 The Voice Foundation.

  16. Genomic ancestry, self-reported "color" and quantitative measures of skin pigmentation in Brazilian admixed siblings.

    Tailce K M Leite

    Full Text Available A current concern in genetic epidemiology studies in admixed populations is that population stratification can lead to spurious results. The Brazilian census classifies individuals according to self-reported "color", but several studies have demonstrated that stratifying according to "color" is not a useful strategy to control for population structure, due to the dissociation between self-reported "color" and genomic ancestry. We report the results of a study in a group of Brazilian siblings in which we measured skin pigmentation using a reflectometer, and estimated genomic ancestry using 21 Ancestry Informative Markers (AIMs. Self-reported "color", according to the Brazilian census, was also available for each participant. This made it possible to evaluate the relationship between self-reported "color" and skin pigmentation, self-reported "color" and genomic ancestry, and skin pigmentation and genomic ancestry. We observed that, although there were significant differences between the three "color" groups in genomic ancestry and skin pigmentation, there was considerable dispersion within each group and substantial overlap between groups. We also saw that there was no good agreement between the "color" categories reported by each member of the sibling pair: 30 out of 86 sibling pairs reported different "color", and in some cases, the sibling reporting the darker "color" category had lighter skin pigmentation. Socioeconomic status was significantly associated with self-reported "color" and genomic ancestry in this sample. This and other studies show that subjective classifications based on self-reported "color", such as the one that is used in the Brazilian census, are inadequate to describe the population structure present in recently admixed populations. Finally, we observed that one of the AIMs included in the panel (rs1426654, which is located in the known pigmentation gene SLC24A5, was strongly associated with skin pigmentation in this sample.

  17. Using Self-reports or Claims to Assess Disease Prevalence: It's Complicated.

    St Clair, Patricia; Gaudette, Étienne; Zhao, Henu; Tysinger, Bryan; Seyedin, Roxanna; Goldman, Dana P

    2017-08-01

    Two common ways of measuring disease prevalence include: (1) using self-reported disease diagnosis from survey responses; and (2) using disease-specific diagnosis codes found in administrative data. Because they do not suffer from self-report biases, claims are often assumed to be more objective. However, it is not clear that claims always produce better prevalence estimates. Conduct an assessment of discrepancies between self-report and claims-based measures for 2 diseases in the US elderly to investigate definition, selection, and measurement error issues which may help explain divergence between claims and self-report estimates of prevalence. Self-reported data from 3 sources are included: the Health and Retirement Study, the Medicare Current Beneficiary Survey, and the National Health and Nutrition Examination Survey. Claims-based disease measurements are provided from Medicare claims linked to Health and Retirement Study and Medicare Current Beneficiary Survey participants, comprehensive claims data from a 20% random sample of Medicare enrollees, and private health insurance claims from Humana Inc. Prevalence of diagnosed disease in the US elderly are computed and compared across sources. Two medical conditions are considered: diabetes and heart attack. Comparisons of diagnosed diabetes and heart attack prevalence show similar trends by source, but claims differ from self-reports with regard to levels. Selection into insurance plans, disease definitions, and the reference period used by algorithms are identified as sources contributing to differences. Claims and self-reports both have strengths and weaknesses, which researchers need to consider when interpreting estimates of prevalence from these 2 sources.

  19. Validity and reliability of stillbirth data using linked self-reported and administrative datasets.

    2015-01-01

    A high rate of stillbirth was previously observed in the Australian Longitudinal Study of Women's Health (ALSWH). Our primary objective was to test the validity and reliability of self-reported stillbirth data linked to state-based administrative datasets. Self-reported data, collected as part of the ALSWH cohort born in 1973-1978, were linked to three administrative datasets for women in New South Wales, Australia (n = 4374): the Midwives Data Collection; Admitted Patient Data Collection; and Perinatal Death Review Database. Linkages were obtained from the Centre for Health Record Linkage for the period 1996-2009. True cases of stillbirth were defined by being consistently recorded in two or more independent data sources. Sensitivity, specificity, positive predictive value, negative predictive value, percent agreement, and kappa statistics were calculated for each dataset. Forty-nine women reported 53 stillbirths. No dataset was 100% accurate. The administrative datasets performed better than self-reported data, with high accuracy and agreement. Self-reported data showed high sensitivity (100%) but low specificity (30%), meaning women who had a stillbirth always reported it, but there was also over-reporting of stillbirths. About half of the misreported cases in the ALSWH were able to be removed by identifying inconsistencies in longitudinal data. Data linkage provides great opportunity to assess the validity and reliability of self-reported study data. Conversely, self-reported study data can help to resolve inconsistencies in administrative datasets. Quantifying the strengths and limitations of both self-reported and administrative data can improve epidemiological research, especially by guiding methods and interpretation of findings.

  20. Only Behavioral But Not Self-Report Measures of Speech Perception Correlate with Cognitive Abilities.

    Heinrich, Antje; Henshaw, Helen; Ferguson, Melanie A

    2016-01-01

    Good speech perception and communication skills in everyday life are crucial for participation and well-being, and are therefore an overarching aim of auditory rehabilitation. Both behavioral and self-report measures can be used to assess these skills. However, correlations between behavioral and self-report speech perception measures are often low. One possible explanation is that there is a mismatch between the specific situations used in the assessment of these skills in each method, and a more careful matching across situations might improve consistency of results. The role that cognition plays in specific speech situations may also be important for understanding communication, as speech perception tests vary in their cognitive demands. In this study, the role of executive function, working memory (WM) and attention in behavioral and self-report measures of speech perception was investigated. Thirty existing hearing aid users with mild-to-moderate hearing loss aged between 50 and 74 years completed a behavioral test battery with speech perception tests ranging from phoneme discrimination in modulated noise (easy) to words in multi-talker babble (medium) and keyword perception in a carrier sentence against a distractor voice (difficult). In addition, a self-report measure of aided communication, residual disability from the Glasgow Hearing Aid Benefit Profile, was obtained. Correlations between speech perception tests and self-report measures were higher when specific speech situations across both were matched. Cognition correlated with behavioral speech perception test results but not with self-report. Only the most difficult speech perception test, keyword perception in a carrier sentence with a competing distractor voice, engaged executive functions in addition to WM. In conclusion, any relationship between behavioral and self-report speech perception is not mediated by a shared correlation with cognition.

  1. Discrepancies between self-reported smoking and carboxyhemoglobin: an analysis of the second national health and nutrition survey.

    Klesges, L M; Klesges, R C; Cigrang, J A

    1992-01-01

    Environmental, self-report, and demographic factors mediated the relationship between self-reported cigarette smoking and carboxyhemoglobin among 2114 smokers and 3918 nonsmokers. Self-reported nonsmokers with carboxyhemoglobin levels between 2% and 3% were more likely to be self-reported ex-smokers, to live in a larger community, and to be younger, less educated, and male than were self-reported nonsmokers with carboxyhemoglobin levels of less than 2%. Self-reported nonsmokers with strong evidence of cigarette consumption (carboxyhemoglobin level greater than 3%) were more likely to be self-reported ex-smokers, younger, less educated, and non-White than were nonsmokers with carboxyhemoglobin levels of less than 2%.

    The adult ADHD Self-Report Scale Thai version (ASRS-V1.1) (18 items) is a questionnaire for screening adult ADHD. To test the validity and reliability of the 18-question ASRS-V1.1 Thai version (ASRS-V1.1 TH) as a screening tool for adult ADHD. The original 18-question ASRS-V1.1 version was translated into Thai. The process was composed of forward-translation, synthesis of the translation, and back translation. Cross cultural adaptation, field testing, and final adjustment were completed consecutively. The 18-question ASRS-V1.1 TH were sent to 1,500 parents of kindergarten and elementary school students in Bangkok, Thailand. The diagnostic interview was randomly selected for 50 parents from the positive result group and 50 parents from the negative result group. The clinical interview for confirming diagnosis was run by 3 psychiatrists who were blinded to the results and used DSM-5 ADHD criteria for diagnosis. The 18-question ASRS-V1.1 TH had satisfactory internal consistency (Cronbach's alpha = 0.92: Cronbach's alpha = 0.87 for inattentive scale, Cronbach's alpha = 0.84 for hyperactive / impulsive scale). For testing the criteria validity, the questionnaire has an adequate. The AUC from the first 6 questions was 0.80 (95% CI: 0.68-0.92) while from the 18 questions was 0.71(95% CI: 0.55-0.86). The 18-question ASRS-V1.1TH is a psychometrically reliable and valid measure for screening adult ADHD in Thai clinical samples, especially the first 6 questions of the questionnaire.

  3. Personality Traits and Susceptibility to Behavioral Biases among a Sample of Polish Stock Market Investors

    Rzeszutek Marcin

    2015-09-01

    Full Text Available The aim of this paper is to investigate whether susceptibility to selected behavioral biases (overconfidence, mental accounting and sunk-cost fallacy is correlated with the Eysenck’s [1978] personality traits (impulsivity, venturesomeness, and empathy. This study was conducted on a sample of 90 retail investors frequently investing on the Warsaw Stock Exchange. Participants filled out a survey made up of two parts: 1 three situational exercises, which assessed susceptibility to behavioral biases and 2 an Impulsiveness Questionnaire, which measures impulsivity, venturesomeness, and empathy. The results demonstrated the relationship between venturesomeness and susceptibility to all behavioral biases explored in this study. We find that higher level of venturesomeness was linked with a lower probability of all behavioral biases included in this study.

At the present time the qualitative theory of such equationsis under rapid development. After a presentation of the fundamental theory of existence, uniqueness and continuability of solutions, a systematic development of stability theory for that class of problems is given which makes the book unique. It addresses to a wide audience such as mathematicians, applied research

  5. Impulsive phase of solar flares: theory

    Mackinnon, A.L.

    1986-01-01

    The paper reviews the theoretical interpretation of impulsive phase phenomena in solar flares. The impulsive phase is defined to be that period of approx. 10 - 100s duration, during which the flare radiative output undergoes its most rapid, dramatic increase and decrease. The interpretation of the various impulsive phase radiation signatures are examined, including the i) hard x-ray emission, ii) radio emission, iii) UV, Hα and white light emissions and iv) gamma-ray emission.

    Background Weight loss has been shown to influence the health outcomes of type 2 diabetes patients. Providing weight management counselling to diabetes patients may help them adopt appropriate weight management behaviours to lose weight. This study determined the association between self-reported receipt of healthcare professional?s weight management counselling and the weight management behaviours of type 2 diabetes patients. Methods This cross-sectional study was conducted among 378 type 2 ...

  7. [Psychosocial work factors and self-reported health in the French national SUMER survey].

    Lesuffleur, Thomas; Chastang, Jean-François; Cavet, Marine; Niedhammer, Isabelle

    2015-01-01

    This study was designed to investigate the associations between psychosocial work factors, using well-known theoretical models and emerging concepts, and self-reported health in the national population of French employees. This study was based on the data of the French national representative SUMER 2010 survey. The sample included 46,962 employees, 26,883 men and 20,079 women, with an 87% participation rate. Self-reported health was measured by means of a single question and was analysed as a binary variable. Psychosocial work factors included factors related to job strain and effort-reward imbalance models, workplace violence and working hours. Associations between psychosocial work factors and self-reported health were studied using weighted logistic regression models adjusted for covariates (age, occupation, economic activity, and other types of occupational exposure). Low decision latitude (skill discretion and decision authority), high psychological demands, low social support (from supervisors for men), low reward (low esteem and low job promotion for both genders and job insecurity for men), bullying and verbal abuse for both genders were associated with self-reported health. This study emphasizes the role of psychosocial work factors as risk factors for poor self-reported health and suggests that the implementation of preventive measures to reduce exposure to psychosocial work factors should be an objective for the improvement of health at work.

  8. In the eyes of the beholder: A non-self-report measure of workplace deviance.

    Stewart, Susan M; Bing, Mark N; Davison, H Kristl; Woehr, David J; McIntyre, Michael D

    2009-01-01

    Because employees may be reluctant to admit to performing deviant acts, the authors of this study reexamined the commonly used self-report measure of workplace deviance developed by R. J. Bennett and S. L. Robinson (2000). Specifically, the self-report measure was modified into a non-self-report measure based on multiple other-reported assessments to address methodological concerns with self-reported information regarding deviant workplace behaviors. The authors assessed the psychometric properties of this new measure by first conducting an exploratory factor analysis, which indicated a 3-factor structure (production deviance, property deviance, and personal aggression). Subsequent confirmatory factor analysis on a different sample verified these findings. Taken together, the results suggest that the content and psychometric qualities of this non-self-report measure of workplace deviance closely represent S. L. Robinson and R. J. Bennett's (1995) original typology of workplace deviance. The potential usefulness of this measure in organizational studies is discussed.

    To identify and quantify demographic correlates of false-negative self-reporting of tobacco use in life insurance applicants. Several studies have assessed the sensitivity of self-reporting for tobacco use in various populations, but statistical examination of the causes of misreporting has been rarer. The very large (488,000 confirmed tobacco users) sample size, US-wide geographic scope, and unique incentive structure of the life insurance application process permit more robust and insurance industry-specific results in this study. Approximately 6.2 million life insurance applicants for whom both tobacco-use interview questions and a confirmatory urine cotinine test were completed between 1999 and 2012 were evaluated for consistency between self-reported and laboratory-confirmed tobacco-use status. The data set was subjected to logistic regression to identify predictors of false negative self-reports (FNSR). False-negative self-reporting was found to be strongly associated with male gender, applicant ages of less than 30 or greater than 60, and low cotinine positivity rates in the applicant's state of residence. Policy face value was also moderately predictive, values above $500,000 associated with moderately higher FNSR. The findings imply that FNSR in life insurance applicants may be the result of complex interactions among financial incentives, geography and presumptive peer groups, and gender.

  10. Accuracy of self-reported drinking: observational verification of 'last occasion' drink estimates of young adults.

    Northcote, Jeremy; Livingston, Michael

    2011-01-01

    As a formative step towards determining the accuracy of self-reported drinking levels commonly used for estimating population alcohol use, the validity of a 'last occasion' self-reporting approach is tested with corresponding field observations of participants' drinking quantity. This study is the first known attempt to validate the accuracy of self-reported alcohol consumption using data from a natural setting. A total of 81 young adults (aged 18-25 years) were purposively selected in Perth, Western Australia. Participants were asked to report the number of alcoholic drinks consumed at nightlife venues 1-2 days after being observed by peer-based researchers on 239 occasions. Complete observation data and self-report estimates were available for 129 sessions, which were fitted with multi-level models assessing the relationship between observed and reported consumption. Participants accurately estimated their consumption when engaging in light to moderate drinking (eight or fewer drinks in a single session), with no significant difference between the mean reported consumption and the mean observed consumption. In contrast, participants underestimated their own consumption by increasing amounts when engaging in heavy drinking of more than eight drinks. It is suggested that recent recall methods in self-report surveys are potentially reasonably accurate measures of actual drinking levels for light to moderate drinkers, but that underestimating of alcohol consumption increases with heavy consumption. Some of the possible reasons for underestimation of heavy drinking are discussed, with both cognitive and socio-cultural factors considered.

  11. The adolescent outcome of hyperactive girls: self-report of psychosocial status.

    Young, Susan; Heptinstall, Ellen; Sonuga-Barke, Edmund J S; Chadwick, Oliver; Taylor, Eric

    2005-03-01

    The aim of the study was to clarify the developmental risk associated with hyperactive behaviour in girls in a longitudinal epidemiological design. This was investigated in a follow-up study of girls who were identified by parent and teacher ratings in a large community survey of 6- and 7-year-olds as showing pervasive hyperactivity or conduct problems or the comorbid mixture of both problems or neither problem. They were later investigated, at the age of 14 to 16 years, with a detailed self-report interview technique. Hyperactivity was a risk factor for later development, even allowing for the coexistence of conduct problems. Hyperactivity predicted academic problems and interpersonal relationship problems. Relationships with parents, by contrast, were not portrayed to be as problematic as relationships with peers and the opposite sex. Their psychological, social and occupational functioning was objectively rated to be more deviant and their self-report showed them to be more ambivalent about their future. There was a trend for hyperactivity to be self-reported as a risk for the development of continuing symptomatology but neither hyperactivity nor conduct problems were self-reported to be a risk for antisocial behaviour, substance misuse or low self-esteem in adolescence. However, they were at risk for the development of state anxiety. The results suggested girls' pattern of functioning may differ from that of boys because girls self-report a more pervasive range of social dysfunction than that previously reported in boys.

    2014-08-01

    The aim of this study was to investigate the relationship between menopause and self-reported sleep quality in Chinese women without vasomotor symptoms. Cross-sectional data were collected from a decoded database of the National Cheng Kung University Hospital. Menopause was defined as absence of menses for at least 12 months or a history of hysterectomy and oophorectomy. Self-reported sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). A higher global PSQI score indicates poorer self-reported sleep quality, and a global PSQI score greater than 5 differentiates poor sleepers from good sleepers. Of the 1,088 women recruited, 353 (32.4%) were in postmenopause status. Postmenopausal women had higher mean (SD) global PSQI scores (8.0 [3.3] vs. 6.1 [2.2], P menopause (β = 1.532; 95% CI, 1.135 to 1.949; P menopause (odds ratio, 1.453; 95% CI, 1.030 to 2.051; P menopause and snoring are associated with an increased risk of poor self-reported sleep quality independently of cardiometabolic factors and lifestyle, whereas long sleep duration is associated with a decreased risk of poor self-reported sleep quality.

    Gloria Macassa

    2018-01-01

    Design and Methods: The study used data collected from 2993 men through a cross sectional survey in the 2014 Health in Equal Terms survey. Descriptive and logistic regression analyses were carried out to study the relationship between fear of crime and self-reported health and stress. Results: There was a statistically significant association between fear of crime and self-reported poor health and stress among men residing in Gävleborg County. In the bivariate analysis, men who reported fear of crime had odds of 1.98 (CI 1.47- 2.66 and 2.23 (CI 1.45-3.41 respectively. Adjusting for demographic, social and economic variables in the multivariate analysis only reduced the odds ratio for self-reported poor health to 1.52 (CI 1.05-2.21 but not for self-reported stress with odds of 2.22 (1.27-3.86. Conclusions: Fear of crime among men was statistically significantly associated with self-reported poor health and stress in Gävleborg County. However, the statistically significant relationship remained even after accounting for demographic, social and economic factors, which warrants further research to better understand the role played by other variables.

  14. Knee motion variability in patients with knee osteoarthritis: the effect of self-reported instability

    Gustafson, Jonathan A.; Robinson, Megan E.; Fitzgerald, G. Kelley; Tashman, Scott; Farrokhi, Shawn

    2015-01-01

    Background Knee osteoarthritis has been previously associated with a stereotypical knee-stiffening gait pattern and reduced knee joint motion variability due to increased antagonist muscle co-contractions and smaller utilized arc of motion during gait. However, episodic self-reported instability may be a sign of excessive motion variability for a large subgroup of patients with knee osteoarthritis. The objective of this work was to evaluate the differences in knee joint motion variability during gait in patients with knee osteoarthritis with and without self-reported instability compared to a control group of older adults with asymptomatic knees. Methods Forty-three subjects, 8 with knee osteoarthritis but no reports of instability (stable), 11 with knee osteoarthritis and self-reported instability (unstable), and 24 without knee osteoarthritis or instability (control) underwent Dynamic Stereo X-ray analysis during a decline gait task on a treadmill. Knee motion variability was assessed using parametric phase plots during the loading response phase of decline gait. Findings The stable group demonstrated decreased sagittal-plane motion variability compared to the control group (p=0.04), while the unstable group demonstrated increased sagittal-plane motion variability compared to the control (p=0.003) and stable groups (pknee motion variability in patients with knee osteoarthritis without self-reported instability supports previous research. However, presence of self-reported instability is associated with increased knee motion variability in patients with knee osteoarthritis and warrants further investigation. PMID:25796536

  15. Pathological gambling: an impulse control disorder? Measurement of impulsivity using neurocognitive tests.

    Dannon, Pinhas N; Shoenfeld, Netta; Rosenberg, Oded; Kertzman, Semion; Kotler, Moshe

    2010-04-01

    Pathological gambling is classified in the DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders) and in the ICD-10 (International Classification of Disease) as an impulse control disorder. The association between impulsivity and pathological gambling remains a matter of debate: some researchers find high levels of impulsivity within pathological gamblers, others report no difference compared to controls, and yet others even suggest that it is lower. In this review we examine the relationship between pathological gambling and impulsivity assessed by various neurocognitive tests. These tests--the Stroop task, the Stop Signal Task, the Matching Familiar Figures Task, the Iowa Gambling Task, the Wisconsin Card Sorting Test, the Tower of London test, and the Continuous Performance Test--demonstrated less impulsivity in gambling behavior. The differences in performance between pathological gamblers and healthy controls on the neurocognitive tasks could be due to addictive behavior features rather than impulsive behavior.

  17. Prevalence and Risk Factors for Self-Reported Violence of Osaka and Seattle Male Youths

    Bui, Laura; Farrington, David P.; Ueda, Mitsuaki; Hill, Karl G.

    2013-01-01

    Traditionally, Japan has been regarded as a country with low crime. Comparative research has given insights into the extent of similarities and differences in crime between America and Japan. The importance of these studies is the examination of whether Western-established criminological knowledge is applicable to non- Western societies like Japan. Unfortunately, comparative self-report studies involving Japan and investigating youth offending are scarce. The current study investigates risk factors and self-reports of violence from Osaka and Seattle male youths. The findings reveal that Japanese male youths self-report a higher prevalence of violence than Seattle male youths. Risk factors for violence, issues of comparability, and prevalence versus strength of relationships of risk factors are examined. It is concluded that the higher prevalence of violence in Osaka is primarily a function of the higher prevalence of troubled peers and risk taking. The findings call for replication of this type of comparative research. PMID:24013769

  18. Stress sensitive electricity based on Ag/cellulose nanofiber aerogel for self-reporting.

    Yao, Qiufang; Fan, Bitao; Xiong, Ye; Wang, Chao; Wang, Hanwei; Jin, Chunde; Sun, Qingfeng

    2017-07-15

    A self-reporting aerogel toward stress sensitive slectricity (SSE) was presented using an interconnected 3D fibrous network of Ag nanoparticles/cellulose nanofiber aerogel (Ag/CNF), which was prepared via combined routes of silver mirror reaction and ultrasonication. Sphere-like Ag nanoparticles (AgNPs) with mean diameter of 74nm were tightly anchored in the cellulose nanofiber through by the coherent interfaces as the conductive materials. The as-prepared Ag/CNF as a self-reporting material for SSE not only possessed quick response and sensitivity, but also be easily recovered after 100th compressive cycles without plastic deformation or degradation in compressive strength. Consequently, Ag/CNF could play a viable role in self-reporting materials as a quick electric-stress responsive sensor. Copyright © 2017 Elsevier Ltd. All rights reserved.

  19. Parents’ Self-Reported Attachment Styles: A Review of Links with Parenting Behaviors, Emotions, and Cognitions

    Jones, Jason D.; Cassidy, Jude; Shaver, Phillip. R.

    2014-01-01

    For decades, attachment scholars have been investigating how parents’ adult attachment orientations relate to the ways in which they parent. Traditionally, this research has been conducted by developmental and clinical psychologists who typically employ the Adult Attachment Interview (AAI) to measure adult attachment. However, dating back to the mid-1990s, social and personality psychologists have been investigating how self-reported adult attachment styles relate to various facets of parenting. The literature on self-reported attachment and parenting has received less attention than AAI research on the same topic and, to date, there is no comprehensive review of this literature. In this article, we review over 60 studies of the links between self-reported attachment styles and parenting, integrate the findings to reach general conclusions, discuss unresolved questions, and suggest future directions. Finally, we discuss the potential benefits to the study of parenting of collaborations among researchers from the developmental and social attachment research traditions. PMID:25024278

  1. Beyond Self-Report: Tools to Compare Estimated and Real-World Smartphone Use

    Andrews, Sally; Ellis, David A.; Shaw, Heather; Piwek, Lukasz

    2015-01-01

    Psychologists typically rely on self-report data when quantifying mobile phone usage, despite little evidence of its validity. In this paper we explore the accuracy of using self-reported estimates when compared with actual smartphone use. We also include source code to process and visualise these data. We compared 23 participants’ actual smartphone use over a two-week period with self-reported estimates and the Mobile Phone Problem Use Scale. Our results indicate that estimated time spent using a smartphone may be an adequate measure of use, unless a greater resolution of data are required. Estimates concerning the number of times an individual used their phone across a typical day did not correlate with actual smartphone use. Neither estimated duration nor number of uses correlated with the Mobile Phone Problem Use Scale. We conclude that estimated smartphone use should be interpreted with caution in psychological research. PMID:26509895

  2. Adolescent Weight Status and Self-Reported School Performance in South Korea

    2011-01-01

    Full Text Available Using a nationally representative sample of 142 783 middle school (13–15 years old and high school (16–18 years old students in South Korea, this study examined whether (1 overweight and obesity are more likely to be associated with lower self-reported school performance; (2 overweight and obese students are more likely to enrol in a vocational high school as opposed to a general high school; (3 the association between obesity and poorer self-reported school performance is mediated through body image stress and health status. We found that excess weight was negatively associated with self-reported school performance among middle and general high school students, and that obese students had a higher probability of being enrolled in a vocational over a general high school. We did not find strong evidence on the mediating role of body image stress and health status.

  3. On the reliability of self-reported health: Evidence from Albanian data

    Nicolas Vaillant

    2012-06-01

    Full Text Available This paper investigates the reliability of self-assessed measures of health using panel data collected in Albania by the World Bank in 2002, 2003 and 2004 through the Living Standard Measurement Study project. As the survey includes questions on a self-assessed measure of health and on more objective health problems, both types of information are combined with a view to understanding how respondents change their answers to the self-reported measures over time. Estimates from random effects ordered Probit models show that differences in self-reported subjective health between individuals are much more marked than those over time, suggesting a strong state dependence in subjective health status. The empirical analysis also reveals respondent consistency, from both a subjective and an objective viewpoint. Self-reported health is much more influenced by permanent shocks than by more transitory illness or injury.

  5. Self-reported health and sickness benefits among parents of children with a disability.

    Wendelborg, Christian; Tøssebro, Jan

    2016-07-02

    This article investigates the possible consequences in self-reported health and receipt of sickness benefits when parenting a child with a disability This study uses data from the population health study, The Nord-Trøndelag Health Study (HUNT 2), and the historical event database, FD-Trygd, which contains Social Security and national insurance data for the Norwegian population. In the analysis, we compare 1587 parents of a child with a disability to other parents. Results indicate that parenting a disabled child impacts on self-reported health, particularly among mothers; however, being a parent to a disabled child has a much stronger effect in explaining the variance in received sickness benefits, and also length of time and frequency of having received sickness benefits. Parents with disabled children report just slightly lower self-reported health but are on sickness benefits more often than other parents which may be attributed to their extended care responsibilities.

  7. Clustering of children's activity behaviour: the use of self-report versus direct measures

    Tremblay Mark S

    2011-05-01

    Full Text Available Abstract While we concur with the objectives of the recent International Journal of Behavioural Nutrition and Physical Activity paper published by Jago and colleagues titled "Physical activity and sedentary behaviour typologies of 10-11 year olds", we feel that the results as currently presented do not support their conclusions. Though the authors created groups of children with dramatically different patterns of self-reported physical activity and sedentary behaviour, an inspection of the objectively measured accelerometry data shows little difference between the groups. Further, in at least one instance the difference between groups was of the opposite direction when using objective measures, as opposed to the self-report measures used in the published analysis. Thus, we caution the authors from making conclusions based on their self-report data, and propose that they re-analyze their data using their objectively measured data instead.

  12. Shock Tube as an Impulsive Application Device

    Soumya Ranjan Nanda

    2017-01-01

    Full Text Available Current investigations solely focus on application of an impulse facility in diverse area of high-speed aerodynamics and structural mechanics. Shock tube, the fundamental impulse facility, is specially designed and calibrated for present objectives. Force measurement experiments are performed on a hemispherical test model integrated with the stress wave force balance. Similar test model is considered for heat transfer measurements using coaxial thermocouple. Force and heat transfer experiments demonstrated that the strain gauge and thermocouple have lag time of 11.5 and 9 microseconds, respectively. Response time of these sensors in measuring the peak load is also measured successfully using shock tube facility. As an outcome, these sensors are found to be suitable for impulse testing. Lastly, the response of aluminum plates subjected to impulsive loading is analyzed by measuring the in-plane strain produced during deformation. Thus, possibility of forming tests in shock is also confirmed.

  13. Factors associated with false-positive self-reported adherence to antihypertensive drugs.

    Tedla, Y G; Bautista, L E

    2017-05-01

    Self-reported medication adherence is known to overestimate true adherence. However, little is known about patient factors that may contribute to the upward bias in self-reported medication adherence. The objective of this study is to examine whether demographic, behavioral, medication and mood factors are associated with being a false-positive self-reported adherer (FPA) to antihypertensive drug treatment. We studied 175 patients (mean age: 50 years; 57% men) from primary-care clinics starting antihypertensive drug treatment. Self-reported adherence (SRA) was measured with the Medication Adherence Report Scale (MARS) and by the number of drug doses missed in the previous week/month, and compared with pill count adherence ratio (PCAR) as gold standard. Data on adherence, demographic, behavioral, medication and mood factors were collected at baseline and every 3 months up to 1 year. FPA was defined as being a non-adherer by PCAR and an adherer by self-report. Mixed effect logistic regression was used for the analysis. Twenty percent of participants were FPA. Anxiety increased (odds ratio (OR): 3.00; P=0.01), whereas smoking (OR: 0.40; P=0.03) and drug side effects (OR: 0.46, P=0.03) decreased the probability for FPA by MARS. Education below high-school completion increased the probability of being an FPA as measured by missing doses in the last month (OR: 1.66; P=0.04) and last week (OR: 1.88; P=0.02). The validity of SRA varies significantly according to drug side effects, behavioral factors and patient's mood. Careful consideration should be given to the use of self-reported measures of adherence among patients likely to be false-positive adherers.

    Working long hours is a potential health hazard. Although self-reporting of working hours in various time frames has been used in epidemiologic studies, its validity is unclear. The objective of this study was to examine the validity and reproducibility of self-reported working hours among Japanese male employees. The participants were 164 male employees of four large-scale companies in Japan. For validity, the Spearman correlation between self-reported working hours in the second survey and the working hours recorded by the company was calculated for the following four time frames: daily working hours, monthly overtime working hours in the last month, average overtime working hours in the last 3 months, and the frequency of long working months (≥45 h/month) within the last 12 months. For reproducibility, the intraclass correlation between the first (September 2013) and second surveys (December 2013) was calculated for each of the four time frames. The Spearman correlations between self-reported working hours and those based on company records were 0.74, 0.81, 0.85, and 0.89 for daily, monthly, 3-monthly, and yearly time periods, respectively. The intraclass correlations for self-reported working hours between the two questionnaire surveys were 0.63, 0.66, 0.73, and 0.87 for the respective time frames. The results of the present study among Japanese male employees suggest that the validity of self-reported working hours is high for all four time frames, whereas the reproducibility is moderate to high.

    Ancestry information can be useful in investigations of diseases with a genetic or infectious background. As the Brazilian population is highly admixed physical traits tend to be poor indicators of ancestry. The assessment of ancestry by ancestry informative markers (AIMs) can exclude the subjectivity of self-declared ethnicity and reported family origin. We aimed to evaluate the reliability of self-reported ethnicity or reported family origin as indicators of genomic ancestry in a female population from the Southeast of Brazil. Two cohorts were included: 404 women asked to self-report their ethnicity (Pop1) and 234 women asked to report their family's origin (Pop2). Identification of AIMs was performed using a panel of 61 markers and results were plotted against parental populations-Amerindian, Western European and Sub-Saharan African-using Structure v2.3.4. In Pop1 57.4 % of women self-reported as white, 34.6 % as brown and 8.0 % as black. Median global European, Amerindian and African contributions were 66.8, 12.6 and 16.6 %. In Pop2, 66.4 % of women declared European origin, 23.9 % African origin and 26.9 % Amerindian. Median global European, Amerindian and African contributions were 80.8, 7.3 and 7.6 %, respectively. Only 31.0 and 21.0 % of the global variation in African and European contributions, respectively, could be explained by self-reported ethnicity and reported family origin only accounted for 20.0 and 5.0 % of the variations observed in African and European ancestries, respectively. Amerindian ancestry did not influence self-reported ethnicity or declared family origin. Neither self-reported ethnicity nor declared family origin are reliable indicators of genomic ancestry in these Brazilian populations.

    Numerous studies have reported weak or moderate correlations between self-reported and accelerometer-assessed physical activity. One explanation is that self-reported physical activity might be biased by demographic, cognitive or other factors. Cognitive function is one factor that could be associated with either overreporting or underreporting of daily physical activity. Difficulties in remembering past physical activities might result in recall bias. Thus, the current study examines whether the cognitive function is associated with differences between self-reported and accelerometer-assessed physical activity. Cross-sectional data from the population-based Activity and Function in the Elderly in Ulm study (ActiFE) were used. A total of 1172 community-dwelling older adults (aged 65-90 years) wore a uniaxial accelerometer (activPAL unit) for a week. Additionally, self-reported physical activity was assessed using the LASA Physical Activity Questionnaire (LAPAQ). Cognitive function was measured with four items (immediate memory, delayed memory, recognition memory, and semantic fluency) from the Consortium to Establish a Registry for Alzheimer's Disease Total Score (CERAD-TS). Mean differences of self-reported and accelerometer-assessed physical activity (MPA) were associated with cognitive function in men (r s  = -.12, p = .002) but not in women. Sex-stratified multiple linear regression analyses showed that MPA declined with high cognitive function in men (β = -.13; p = .015). Results suggest that self-reported physical activity should be interpreted with caution in older populations, as cognitive function was one factor that explained the differences between objective and subjective physical activity measurements.

    In Canada, indigenous peoples suffer from a multitude of health disparities. To better understand these disparities, this study aims to examine the social determinants of self-reported health for indigenous peoples in Canada. This study uses data from Statistics Canada's Aboriginal Peoples Survey 2012. Multinomial logistic regression models were used to examine how selected social determinants of health are associated with self-reported health among off-reserve First Nations and Métis peoples in Canada. Our analysis shows that being older, female, and living in urban settings were significantly associated with negative ratings of self-reported health status among the indigenous respondents. Additionally, we found that higher income and levels of education were strongly and significantly associated with positive ratings of self-reported health status. Compared with indigenous peoples with an education level of grade 8 or lower, respondents with higher education were 10 times (5.35-22.48) more likely to report 'excellent' and 'very good' health. Respondents who earned more than $40,000 annually were three times (2.17-4.72) more likely to report 'excellent' and 'very good' health compared with those who earned less than $20,000 annually. When interacted with income, we also found that volunteering in the community is associated with better self-reported health. There are known protective determinants (income and education) and risk determinants (location of residence, gender, and age) which are associated with self-reported health status among off-reserve First Nations and Métis peoples. For indigenous-specific determinants, volunteering in the community appears to be associated with self-perceived health status. Thus, addressing these determinants will be necessary to achieve better health outcomes for indigenous peoples in Canada. Next steps include developing indigenous-specific social determinants of health indicators that adequately measure culture, connection

    2013-09-01

    The aim of this study was to evaluate the association between Agent Orange exposure and self-reported diseases in Korean Vietnam veterans. A postal survey of 114 562 Vietnam veterans was conducted. The perceived exposure to Agent Orange was assessed by a 6-item questionnaire. Two proximity-based Agent Orange exposure indices were constructed using division/brigade-level and battalion/company-level unit information. Adjusted odds ratios (ORs) for age and other confounders were calculated using a logistic regression model. The prevalence of all self-reported diseases showed monotonically increasing trends as the levels of perceived self-reported exposure increased. The ORs for colon cancer (OR, 1.13), leukemia (OR, 1.56), hypertension (OR, 1.03), peripheral vasculopathy (OR, 1.07), enterocolitis (OR, 1.07), peripheral neuropathy (OR, 1.07), multiple nerve palsy (OR, 1.14), multiple sclerosis (OR, 1.24), skin diseases (OR, 1.05), psychotic diseases (OR, 1.07) and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the division/brigade-level proximity-based exposure analysis, compared to the low exposure group. The ORs for cerebral infarction (OR, 1.08), chronic bronchitis (OR, 1.05), multiple nerve palsy (OR, 1.07), multiple sclerosis (OR, 1.16), skin diseases (OR, 1.05), and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the battalion/company-level analysis. Korean Vietnam veterans with high exposure to Agent Orange experienced a higher prevalence of several self-reported chronic diseases compared to those with low exposure by proximity-based exposure assessment. The strong positive associations between perceived self-reported exposure and all self-reported diseases should be evaluated with discretion because the likelihood of reporting diseases was directly related to the perceived intensity of Agent Orange exposure.

  19. How reliable are self-reports of HIV status disclosure? Evidence from couples in Malawi.

    Conroy, Amy A; Wong, Lauren H

    2015-11-01

    The majority of research on human immunodeficiency virus (HIV) disclosure utilizes the perspective from a single individual, which cannot be substantiated in the absence of supporting data such as from a primary partner. The objectives of this study were to evaluate: (1) the extent to which self-reported HIV disclosure was confirmed by a primary partner; (2) individual and relationship-level predictors of self-reported versus confirmed disclosure; and (3) whether confirmed disclosure was a stronger predictor of correctly assessing a partner's HIV status compared to self-reported disclosure. As part of an 8-wave longitudinal study from 2009 to 2011 in southern Malawi, 366 individuals (183 couples) were interviewed about their primary relationship (wave 3), individually tested for HIV (wave 4), and then asked whether they disclosed to their primary partner (wave 5). While 93% of respondents reported that they disclosed, only 64% of respondents had confirmed reports from their partner. Having communicated with partner about HIV was positively associated with self-reported disclosure; this association remained significant but became more precise in the models for confirmed disclosure. Confirmed disclosure, but not self-report, was a significant predictor of correctly assessing a partner's HIV status. Being male, having lower perceived partner infidelity, having higher relationship unity, and testing HIV-negative were positively and significantly associated with correct assessment. Dyadic data from two partners provide an improved measure of disclosure as compared to a single individual's self-report and could be used to identify behavioral and biomedical opportunities to prevent HIV transmission within couples.

    To compare objective food store and eating-out receipts with self-reported household food expenditures. The Seattle Obesity Study II was based on a representative sample of King County adults, Washington, USA. Self-reported household food expenditures were modeled on the Flexible Consumer Behavior Survey (FCBS) Module from 2007 to 2009 National Health and Nutrition Examination Survey (NHANES). Objective food expenditure data were collected using receipts. Self-reported food expenditures for 447 participants were compared with receipts using paired t-tests, Bland-Altman plots and κ-statistics. Bias by sociodemographics was also examined. Self-reported expenditures closely matched with objective receipt data. Paired t-tests showed no significant differences between receipts and self-reported data on total food expenditures, expenditures at food stores or eating out. However, the highest-income strata showed weaker agreement. Bland-Altman plots confirmed no significant bias across both methods-mean difference: 6.4; agreement limits: -123.5 to 143.4 for total food expenditures, mean difference 5.7 for food stores and mean difference 1.7 for eating out. The κ-statistics showed good agreement for each (κ 0.51, 0.41 and 0.49 respectively. Households with higher education and income had significantly more number of receipts and higher food expenditures. Self-reported food expenditures using NHANES questions, both for food stores and eating out, serve as a decent proxy for objective household food expenditures from receipts. This method should be used with caution among high-income populations, or with high food expenditures. This is the first validation of the FCBS food expenditures question using food store and eating-out receipts.

    To assess the reliability and validity of self-reported cannabis dose and potency measures. Cross-sectional study comparing self-reports with objective measures of amount of cannabis and delta-9-tetrahydrocannabinol (THC) concentration. Ecological study with assessments at participants' homes or in a coffee shop. Young adult frequent cannabis users (n = 106) from the Dutch Cannabis Dependence (CanDep) study. The objectively measured amount of cannabis per joint (dose in grams) was compared with self-reported estimates using a prompt card and average number of joints made from 1 g of cannabis. In addition, objectively assessed THC concentration in the participant's cannabis was compared with self-reported level of intoxication, subjective estimate of cannabis potency and price per gram of cannabis. Objective estimates of doses per joint (0.07-0.88 g/joint) and cannabis potency (1.1-24.7%) varied widely. Self-reported measures of dose were imprecise, but at group level, average dose per joint was estimated accurately with the number of joints made from 1 g [limit of agreement (LOA) = -0.02 g, 95% confidence interval (CI) = -0.29; 0.26], whereas the prompt card resulted in serious underestimation (LOA = 0.14 g, 95% CI = -0.10; 0.37). THC concentration in cannabis was associated with subjective potency ['average' 3.77% (P = 0.002) and '(very) strong' 5.13% more THC (P cannabis] and with cannabis price (about 1% increase in THC concentration per euro spent on 1 g of cannabis, P cannabis use appear at best to be associated weakly with objective measures. Of the self-report measures, number of joints per gram, cannabis price and subjective potency have at least some validity. © 2013 Society for the Study of Addiction.

  2. Predictors of self-reported academic performance among undergraduate medical students of Hawassa University, Ethiopia.

    Gedefaw, Abel; Tilahun, Birkneh; Asefa, Anteneh

    2015-01-01

    This study was conducted to identify predictors of self-reported academic performance in undergraduate medical students at Hawassa University. An analytical cross-sectional study involving 592 undergraduate medical students was conducted in November 2012. The academic performance of the study subjects was measured by self-reported cumulative grade point average (GPA) using a self-administered questionnaire. Data were entered and analyzed using Statistical Package for the Social Sciences version 16 software. Pearson's bivariate correlations, multiple linear regression, and multiple logistic regression were used to identify predictors of academic performance. The self-reported academic performance of students had been decreasing as the academic years progressed, with the highest and lowest performance being in the premedicine (mean GPA 3.47) and clinical I (mean GPA 2.71) years, respectively. One hundred and fifty-eight (26.7%) of the participants had ever been delayed, 37 (6.2%) had ever re-sat for examination, and two (0.3%) had ever been warned due to academic failure. The overall variation in self-reported academic performance of the students was 32.8%. Participant age alone explained 21.9% of the variation. On the other hand, university entrance examination results, substance use at university, and medicine as first choice by students were identified as predictors of variation in self-reported academic performance, accounting for 6.9%, 2.7%, and academic performance was explained by the studied variables. Hence, efficacious mechanisms should be designed to combat the intervenable determinants of self-reported academic performance, like substance use and a low medical school entrance examination result. Further studies should also be undertaken to gain a better understanding of other unstudied determinants, like personality, learning style, cognitive ability, and the system used for academic evaluation.

  3. Reliability and validity of two self-report measures of cognitive flexibility.

    2014-12-01

    Neuropsychological testing currently represents the gold standard in assessing cognitive flexibility. However, this format presents some challenges in terms of time and skills required for administration, scoring, and interpretation. Two self-report measures of cognitive flexibility have been developed to measure aspects of cognitive flexibility in everyday settings, although neither has been validated in an older sample. In this study, we investigated the psychometric properties of 2 self-report measures of cognitive flexibility, the Cognitive Flexibility Inventory (CFI; Dennis & Vander Wal, 2010) and the Cognitive Flexibility Scale (CFS; Martin & Rubin, 1995), against neuropsychological measures of cognitive flexibility in a clinical sample of 47 older adults with comorbid anxiety and depression and a nonclinical sample of 53 community-dwelling older adults. Internal consistency was good for the CFS and CFI in all samples. The clinical sample reported poorer cognitive flexibility than did the nonclinical sample on self-report measures and performed more poorly on some neuropsychological measures. There was evidence of convergent validity between the 2 self-report measures but little relationship between the self-report and neuropsychological measures of cognitive flexibility, suggesting that self-report measures assess a different aspect of cognitive flexibility than does neuropsychological testing. Divergent validity was weak from measures of anxiety and depression in the combined and nonclinical samples but acceptable in the clinical sample. Results suggest that these measures are suitable for use with an older adult sample but do not assess the same aspects of cognitive flexibility as are assessed by neuropsychological assessment.

  4. Adult self-reported and objectively monitored physical activity and sedentary behavior: NHANES 2005–2006

    2013-01-01

    Background It remains unclear what people are attempting to communicate, in terms of objectively monitored behavior, when describing their physical activity and sedentary behavior through self-report. The purpose of this study was to examine various objectively monitored accelerometer variables (e.g., moderate-to-vigorous physical activity [MVPA], steps/day, sedentary time, etc.) across categories of self-reported MVPA (activity (UODA; “mostly sitting” vs. “stand, walk, lift, or carry”), and leisure-time sedentary behavior (LTSB; ≥ 3 vs. behavior between categories of self-reported MVPA, UODA, and LTSB. Results On average, adults reporting compliance with physical activity guidelines (≥ 150 minutes/week of MVPA) accumulated more objectively measured physical activity and similar amounts of sedentary time relative to those reporting not achieving guidelines. Adults reporting their daily UODA as “mostly sitting” or accruing ≥ 3 hours/day of LTSB accumulated less objectively monitored physical activity and more sedentary time than those who described their UODA as “stand, walk, lift, or carry” or accrued active cross-classified category (7,935 steps/day; ≥ 150 minutes/week of self-reported MVPA, “stand, walk, lift, or carry” UODA, and active cross-classified category (3,532 steps/day; physical activity indicators varied significantly between self-reported MVPA, UODA, and LTSB categories, while objectively monitored sedentary time only varied between UODA and LTSB categories. Cross-classifications of self-reported MVPA, UODA, and LTSB responses depict a greater range of physical activity than viewing dichotomous responses for these variables one-at-a-time. PMID:24215625

  5. Self-Reported and FEMA Flood Exposure Assessment after Hurricane Sandy: Association with Mental Health Outcomes.

    Wil Lieberman-Cribbin

    Full Text Available Hurricane Sandy caused extensive physical and economic damage; the long-term mental health consequences are unknown. Flooding is a central component of hurricane exposure, influencing mental health through multiple pathways that unfold over months after flooding recedes. Here we assess the concordance in self-reported and Federal Emergency Management (FEMA flood exposure after Hurricane Sandy and determine the associations between flooding and anxiety, depression, and post-traumatic stress disorder (PTSD. Self-reported flood data and mental health symptoms were obtained through validated questionnaires from New York City and Long Island residents (N = 1231 following Sandy. Self-reported flood data was compared to FEMA data obtained from the FEMA Modeling Task Force Hurricane Sandy Impact Analysis. Multivariable logistic regressions were performed to determine the relationship between flooding exposure and mental health outcomes. There were significant discrepancies between self-reported and FEMA flood exposure data. Self-reported dichotomous flooding was positively associated with anxiety (ORadj: 1.5 [95% CI: 1.1-1.9], depression (ORadj: 1.7 [1.3-2.2], and PTSD (ORadj: 2.5 [1.8-3.4], while self-reported continuous flooding was associated with depression (ORadj: 1.1 [1.01-1.12] and PTSD (ORadj: 1.2 [1.1-1.2]. Models with FEMA dichotomous flooding (ORadj: 2.1 [1.5-2.8] or FEMA continuous flooding (ORadj: 1.1 [1.1-1.2] were only significantly associated with PTSD. Associations between mental health and flooding vary according to type of flood exposure measure utilized. Future hurricane preparedness and recovery efforts must integrate micro and macro-level flood exposures in order to accurately determine flood exposure risk during storms and realize the long-term importance of flooding on these three mental health symptoms.

  6. Self-reported physical activity is associated with cognitive function in lean, but not obese individuals.

    Galioto Wiedemann, R; Calvo, D; Meister, J; Spitznagel, M B

    2014-12-01

    Convergent evidence demonstrates that greater physical activity is associated with better cognitive functioning across many patient and healthy samples. However, this relationship has not been well examined among obese individuals and remains unclear. The present study examined the relationship between performance-based measures of attention/executive function and self-reported physical activity, as measured by the International Physical Activity Questionnaire, among lean (n = 36) and obese (n = 36) college students. Lean individuals performed better than obese individuals on measures of attention/executive function. No significant differences in self-reported physical activity emerged between weight groups. Higher self-reported physical activity was related to faster reaction time in lean individuals but slower reaction time in obese individuals. Additionally, in lean individuals, higher levels of self-reported physical activity were related to more errors on a task of speeded inhibitory control. The results are consistent with previous research demonstrating that greater physical activity is associated with faster attention and executive function abilities in healthy samples and highlight the importance of examining reaction time and accuracy indices separately on these measures. The lack of association among obese individuals may be due in part to inaccurate self-report in the current study. Additionally, the cognitive consequences of obesity may outweigh the benefits of physical activity in this group. Future work should investigate these associations in obese individuals using physical activity interventions, as well as a combination of self-report and objective measures to investigate discrepancies in reporting. © 2014 The Authors.

  7. Sex differences in the developmental trajectories of impulse control and sensation-seeking from early adolescence to early adulthood.

    Shulman, Elizabeth P; Harden, K Paige; Chein, Jason M; Steinberg, Laurence

    2015-01-01

    It has been proposed that high rates of risk-taking in adolescence are partly attributable to patterns of neurobiological development that promote an increase in sensation-seeking tendencies at a time when impulse control is still developing. It is not known, however, whether this pattern is the same for males and females. The present study investigates sex differences in the developmental trajectories of self-reported impulse control and sensation-seeking between the ages of 10 and 25 using longitudinal data from the National Longitudinal Study of Youth 1979 Child and Young Adult Survey (N = 8,270; 49% female; 33% Black, 22% Hispanic, 45% Non-Black, Non-Hispanic). Prior work has found that, consistent with the dual-systems model of adolescent neurobiological development, sensation-seeking rises and falls across this age span, whereas impulse control increases into the 20s. In the present study, we find that this same general pattern holds for both males and females, but with some key differences. As expected, males exhibit higher levels of sensation-seeking and lower levels of impulse control than females. Differences also emerged in the shapes of the developmental trajectories. Females reach peak levels of sensation-seeking earlier than males (consistent with the idea that sensation-seeking is linked to pubertal development) and decline in sensation-seeking more rapidly thereafter. Also, males increase in impulse control more gradually than females. Consequently, sex differences in both impulse control and sensation-seeking increase with age. The findings suggest that the window of heightened vulnerability to risk-taking during adolescence may be greater in magnitude and more protracted for males than for females.

  8. Moving beyond the trait conceptualization of self-esteem: the prospective effect of impulsiveness, coping, and risky behavior engagement.

    Auerbach, Randy P; Gardiner, Casey K

    2012-10-01

    Past research has largely focused on examining self-esteem as an independent as opposed to a dependent variable. At the same time, research suggests that during adolescence, self-esteem is subject to yearly, monthly, as well as daily change, and consequently, it is important to identify underlying vulnerability factors and behaviors, which shape self-esteem lability. In the current multi-wave, longitudinal study, 142 adolescents between the ages of 12-18 completed monthly assessments across 4 months. At the initial assessment, adolescents provided self-report data pertaining to impulsiveness, maladaptive coping, risky behavior engagement, and self-esteem. At each of the follow-up assessments, adolescents provided information about risky behavior engagement and self-esteem. Results of time-lagged, idiographic multilevel mediation analyzes indicated that risky behavior engagement mediated the relationship between impulsiveness/maladaptive coping and subsequent low self-esteem. Critically, when included in the same model, impulsiveness was significant above and beyond maladaptive coping. Additionally, the reverse model with self-esteem as the predictor and risky behavior included as the dependent variable was not significant suggesting that our effect was unidirectional. As a whole, these findings suggest that impulsive youth may engage in behaviors, which ultimately precipitate negative self-evaluations and transient declines in self-esteem.

  9. Focusing on symptoms rather than diagnoses in brain dysfunction: conscious and nonconscious expression in impulsiveness and decision-making.

    Palomo, T; Beninger, R J; Kostrzewa, R M; Archer, T

    2008-08-01

    Symptoms and syndromes in neuropathology, whether expressed in conscious or nonconscious behaviour, remain imbedded in often complex diagnostic categories. Symptom-based strategies for studying brain disease states are driven by assessments of presenting symptoms, signs, assay results, neuroimages and biomarkers. In the present account, symptom-based strategies are contrasted with existing diagnostic classifications. Topics include brain areas and regional circuitry underlying decision-making and impulsiveness, and motor and learned expressions of explicit and implicit processes. In three self-report studies on young adult and adolescent healthy individuals, it was observed that linear regression analyses between positive and negative affect, self-esteem, four different types of situational motivation: intrinsic, identified regulation, extrinsic regulation and amotivation, and impulsiveness predicted significant associations between impulsiveness with negative affect and lack of motivation (i.e., amotivation) and internal locus of control, on the one hand, and non-impulsiveness with positive affect, self-esteem, and high motivation (i.e., intrinsic motivation and identified regulation), on the other. Although presymptomatic, these cognitive-affective characterizations illustrate individuals' choice behaviour in appraisals of situations, events and proclivities essentially of distal perspective. Neuropathological expressions provide the proximal realities of symptoms and syndromes with underlying dysfunctionality of brain regions, circuits and molecular mechanisms.

    2015-09-01

    This study investigated the degree to which facets of impulsiveness predicted future binge eating and problem gambling, 2 theorized forms of behavioral addiction. Participants were 596 women and 406 men from 4 age cohorts randomly recruited from a Canadian province. Participants completed self-report measures of 3 facets of impulsiveness (negative urgency, sensation seeking, lack of persistence), binge-eating frequency, and problem-gambling symptoms. Impulsiveness was assessed at baseline, and assessments of binge eating and problem gambling were followed up after 3 years. Weighted data were analyzed using zero-inflated negative binomial and Poisson regression models. We found evidence of transdiagnostic and disorder-specific predictors of binge eating and problem gambling. Negative urgency emerged as a common predictor of binge eating and problem gambling among women and men. There were disorder-specific personality traits identified among men only: High lack-of-persistence scores predicted binge eating and high sensation-seeking scores predicted problem gambling. Among women, younger age predicted binge eating and older age predicted problem gambling. Thus, there are gender differences in facets of impulsiveness that longitudinally predict binge eating and problem gambling, suggesting that treatments for these behaviors should consider gender-specific personality and demographic traits in addition to the common personality trait of negative urgency.

  11. Project NEO Specific Impulse Testing Solutions

    Baffa, Bill

    2018-01-01

    The Neo test stand is currently configured to fire a horizontally mounted rocket motor with up to 6500 lbf thrust. Currently, the Neo test stand can measure flow of liquid propellant and oxidizer, pressures residing in the closed system up to the combustion chamber. The current configuration does not have the ability to provide all data needed to compute specific impulse. This presents three methods to outfit the NEO test fixture with instrumentation allowing for calculation of specific impulse.

    2011-01-01

    This paper investigates outer synchronization of complex networks, especially, outer complete synchronization and outer anti-synchronization between the driving network and the response network. Employing the impulsive control method which is uncontinuous, simple, efficient, low-cost and easy to implement in practical applications, we obtain some sufficient conditions of outer complete synchronization and outer anti-synchronization between two complex networks. Numerical simulations demonstrate the effectiveness of the proposed impulsive control scheme. (general)

    Compressible magnetohydrodynamic (MHD) simulation is carried out in order to investigate energy relaxation process of the driven magnetic reconnection in an open finite system through a long time calculation. It is found that a very impulsive energy release occurs in an intermittent fashion through magnetic reconnection for a continuous magnetic flux injection on the boundary. We focus our attention on the detailed process in the impulsive phase, which is the reconnection rate is remarkably enhanced up. (author)

    The objectives of this study were to evaluate self-reporting of weight, height, and waist circumference, and to compare that perception with the real measurements in college students of the MESPYN cohort--Medellin, Salud Pública y Nutrición--from the University of Antioquia (UdeA), Colombia. A cross-sectional study was conducted starting with the first measurement of the MESPYN Cohort 2009-2010. The sample included volunteer students from different academic areas. Self-perception of weight, height, and waist circumference were recorded before the real measurements were performed. Intraclass correlation coefficients (ICC) were calculated for all the variables, and an alpha of 0.05 was used. The concordance between real measurements and self-referred values was evaluated with the Bland and Altman method. 424 volunteer students were included. The average real weight (kg) in males was 67.4 +/- 10.4 and self-reported: 67.0 +/- 11.0; in females the real value was 55.7 +/- 10.1 and self-reported: 55.0 +/- 9.0. The average real height (m) in males was 1.73 +/- 6.1 and self-reported: 1.73 +/- 6.0; in females the real value was 1.60 +/- 5.9 and self-reported: 1.61 +/- 6.0. In males, the average real waist circumference (cm) was 76.6 +/- 8.0 and self-reported: 75.0 +/- 14.0; in females the real value was 69.9 +/- 8.0 and self-reported: 70.0 +/- 9.0. Weight ICC: 0.956, 95% CI (0.95; 0.97), (p < 0.01); height ICC: 0.953, 95%IC (0.91; 0.97), (p < 0.01), and waist circumference ICC: 0.593, 95% IC (0.55; 0.65), (p < 0.01). In conclusion, anthropometric nutritional evaluation of UdeA students can be performed with self-reported data for weight and height, but the evaluation of abdominal obesity requires direct measurement of waist circumference.

    This study investigated the effects of reliability and validity "enhancers" on fidelity of self-report data in an analogue therapy situation. Under the guise of a Concentration Skills Training Program, 57 Ss were assigned randomly to one of the following conditions: (a) Reliability Enhancement; (b) Truth Talk; (c) No Comment Control. Results indicated significant differences among groups (p less than .05). In addition, tests of multiple comparisons revealed that Reliability Enhancement was significantly different from Truth Talk in occurrences of unreliability (p less than .05). These findings are discussed in light of the increased reliance on self-report data in behavioral intervention, and recommendations are made for future research.

    Objective: To examine the relationship between the prevalence of self-reported myopia and outdoor activities among middle school students and to explore the influence factors of the self-reported myopia. Methods: A total of 12 979 participants were recruited from junior and senior middle school students in in Shenzhen, Nanchang, Zhengzhou and Shenyang by random cluster sampling method between December 2015 and March 2016. All participants completed an anonymous questionnaire to collect the information of demographic characteristics, self-reported myopia, outdoor activities, etc. 12 603 out of 12 979 copies of questionnaire were valid. The prevalence of self-reported myopia was compared among middle school students with different characteristics. Logistic regression models were used to analyze the relationship between myopia and outdoor activities. Results: The prevalence of self-reported myopia among middle school students was 69.6% (8 766/12 603); which was separately 52.1% (1 216/2 335) in seventh grader, 61.6% (1 459/2 369) in eighth grader, 69.0%(1 470/2 129) in ninth grader, 80.0% (1 812/2 265) in freshmen, 79.4% (1 622/2 042) in sophomore, and 81.1%(1 187/1 463) in junior. The prevalence of self-reported myopia showed an increasing trend with the increase of grade (χ(2)=639.67, Pmiddle school students ( OR= 1.58, 95 %CI: 1.36-1.82). The risk of self-reported myopia were significantly decreased by always physical exercise and recreational activities after school among middle school students: the ORs were separately 0.67 (95 %CI: 0.57-0.78) for physical exercise and 0.77 (95 %CI: 0.64-0.92) for recreational activities. After stratified analysis by the parents' myopia status, in non-myopic parents group, exercise and recreational activities after school among middle school students decreased the risk of myopia: the ORs were separately 0.68 (95 %CI: 0.55-0.82) for physical exercise and 0.76 (95 %CI: 0.61-0.95) for recreational activities; in either myopic parent

Methods: An analytical cross-sectional study involving 592 undergraduate medical students was conducted in November 2012. The academic performance of the study subjects was measured by self-reported cumulative grade point average (GPA using a self-administered questionnaire. Data were entered and analyzed using Statistical Package for the Social Sciences version 16 software. Pearson's bivariate correlations, multiple linear regression, and multiple logistic regression were used to identify predictors of academic performance. Results: The self-reported academic performance of students had been decreasing as the academic years progressed, with the highest and lowest performance being in the premedicine (mean GPA 3.47 and clinical I (mean GPA 2.71 years, respectively. One hundred and fifty-eight (26.7% of the participants had ever been delayed, 37 (6.2% had ever re-sat for examination, and two (0.3% had ever been warned due to academic failure. The overall variation in self-reported academic performance of the students was 32.8%. Participant age alone explained 21.9% of the variation. On the other hand, university entrance examination results, substance use at university, and medicine as first choice by students were identified as predictors of variation in self-reported academic performance, accounting for 6.9%, 2.7%, and <1% of the variation, respectively. Students who had never used tobacco, alcohol, or khat after starting university were twice as likely to score a self-reported cumulative GPA above 3.0 (adjusted odds ratio 1.95, 95

    2013-06-01

    Hypnotic responding might be due to attenuated frontal lobe functioning after the hypnotic induction. Little is known about whether personality traits linked with frontal functioning are associated with responsiveness to hypnotic suggestions. We assessed whether hypnotic suggestibility is related to the traits of self-control and impulsivity in 154 participants who completed the Brief Self-Control Scale, the Self-Regulation Scale, the Barratt Impulsiveness Scale (BIS-11), and the Harvard Group Scale of Hypnotic Susceptibility (HGSHS:A). BIS-11 non-planning impulsivity correlated positively with HGSHS:A (Bonferroni-corrected). Furthermore, in the best model emerging from a stepwise multiple regression, both non-planning impulsivity and self-control positively predicted hypnotic suggestibility, and there was an interaction of BIS-11 motor impulsivity with gender. For men only, motor impulsivity tended to predict hypnotic suggestibility. Hypnotic suggestibility is associated with personality traits linked with frontal functioning, and hypnotic responding in men and women might differ. Copyright © 2013 Elsevier Inc.

  10. Narcissism predicts impulsive buying: phenotypic and genetic evidence

    Cai, Huajian; Shi, Yuanyuan; Fang, Xiang; Luo, Yu L. L.

    2015-01-01

    Impulsive buying makes billions of dollars for retail businesses every year, particularly in an era of thriving e-commerce. Narcissism, characterized by impulsivity and materialism, may serve as a potential antecedent to impulsive buying. To test this hypothesis, two studies examined the relationship between narcissism and impulsive buying. In study 1, we surveyed narcissism and the impulsive buying tendency among an online sample and found that while adaptive narcissism was not correlated wi...

  11. General habit propensity relates to the sensation seeking subdomain of impulsivity but not obesity

    Anja Dietrich

    2016-11-01

    Full Text Available According to dual-system theory, instrumental learning and performance depend on the balance between goal-directed and habitual action control. Overreliance on habits has been argued to characterize clinical conditions such as drug addiction or obsessive-compulsive disorder as well as obesity and excessive impulsivity. A tendency towards habitual action control in obesity has already been indicated in the food domain. However, impairments might not be restricted to eating behavior. This has been suggested by domain-general obesity-associated disturbances in executive function as well as alterations in corticostriatal circuits underlying the goal-directed and habitual systems. In this study we examined the balance of goal-directed and habitual action control in a sample of normal-weight, overweight, and obese participants (n=105 using the slips-of-action test in a non-food context. We tested for continuous or group-based associations between body weight status (BMI and the devaluation sensitivity index (DSI, a parameter representing the balance of the goal-directed and habitual systems in action control. As personality differences in the domain of impulsivity might affect this relationship, we also examined whether the interaction between BMI and self-reported impulsivity, based on the UPPS Impulsive Behavior Scale, was related to the DSI. In addition to that, we tested for direct, i.e., weight status independent, relationships between UPPS subdomains of impulsivity and the DSI. We failed to find evidence for a relationship between weight status and sensitivity to devaluation as indexed by the DSI. However, independent of weight status, we observed lower sensitivity to devaluation in sensation seekers, a subtype of impulsivity. To conclude, behavioral flexibility in the sense of disturbances in the balance between the habitual and goal-directed systems seems to be unaffected by weight status in a non-food context. Consequently, stimuli and

    To investigate the association between self-reported sleep duration and serum vitamin D level in elderly Korean adults. Cross-sectional data analysis. Korean National Health and Nutrition Examination Survey 2010. Noninstitutionalized adults aged 60 to 80 (N = 1,614). The confounding variables were serum 25-hydroxy vitamin D level, age, sex, body mass index, smoking history, alcohol consumption, and self-reported daily sun exposure and sleep duration. Self-reported daily sleep duration was divided into four groups: Q1 (≤4 hours), Q2 (5-6 hours), Q3 (7-8 hours), and Q4 (≥9 hours). Mean serum vitamin D levels of subjects in the Q1, Q2, Q3, and Q4 groups were 44.18, 48.08, 48.83, and 51.78 nmol/L, respectively. On multivariate linear regression analysis, subjects in the Q2 (B = 3.80, 95% confidence interval (CI) = 0.42-7.19), Q3 (B = 4.89, 95% CI = 1.54-8.24), and Q4 (B = 5.18, 95% CI = 0.78-9.58) groups had significantly higher serum vitamin D levels than subjects in the Q1 group. Serum vitamin D level is positively associated with self-reported daily sleep duration in elderly Korean individuals. These results suggest that inadequate sleep duration may be associated with lower vitamin D levels in elderly adults. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

  18. Are there meaningful individual differences in temporal inconsistency in self-reported personality?

    Soubelet, Andrea; Salthouse, Timothy A; Oishi, Shigehiro

    2014-11-01

    The current project had three goals. The first was to examine whether it is meaningful to refer to across-time variability in self-reported personality as an individual differences characteristic. The second was to investigate whether negative affect was associated with variability in self-reported personality, while controlling for mean levels, and correcting for measurement errors. The third goal was to examine whether variability in self-reported personality would be larger among young adults than among older adults, and whether the relation of variability with negative affect would be stronger at older ages than at younger ages. Two moderately large samples of participants completed the International Item Pool Personality questionnaire assessing the Big Five personality dimensions either twice or thrice, in addition to several measures of negative affect. Results were consistent with the hypothesis that within-person variability in self-reported personality is a meaningful individual difference characteristic. Some people exhibited greater across-time variability than others after removing measurement error, and people who showed temporal instability in one trait also exhibited temporal instability across the other four traits. However, temporal variability was not related to negative affect, and there was no evidence that either temporal variability or its association with negative affect varied with age.

    2017-05-01

    Muscle fatigue and acute muscle soreness occur after exercise. Application of a local vibration intervention may reduce the consequences of fatigue and soreness. To examine the effects of a local vibration intervention after a bout of exercise on balance, power, and self-reported pain. Single-blind crossover study. Laboratory. 19 healthy, moderately active subjects. After a 30-min bout of full-body exercise, subjects received either an active or a sham vibration intervention. The active vibration intervention was performed bilaterally over the muscle bellies of the triceps surae, quadriceps, hamstrings, and gluteals. At least 1 wk later, subjects repeated the bout, receiving the other vibration intervention. Static balance, dynamic balance, power, and self-reported pain were measured at baseline, after the vibration intervention, and 24 h postexercise. After the bout of exercise, subjects had reduced static and dynamic balance and increased self-reported pain regardless of vibration intervention. There were no differences between outcome measures between the active and sham vibration conditions. The local vibration intervention did not affect balance, power, or self-reported pain.

    Full Text Available Abstract Background To evaluate the life-time prevalence of self reported whiplash injury and the relationship to chronic musculoskeletal complaints (MSCs and headache in a large unselected adult population. Methods Between 1995 and 1997, all inhabitants 20 years and older in Nord-Trondelag county in Norway were invited to a comprehensive health survey. Out of 92,936 eligible for participation, a total of 59,104 individuals (63.6% answered the question about whiplash injury (whiplash. Among these, 46,895 (79.3% responded to the questions of musculoskeletal complaints and headache. Results The total life-time prevalence of self reported whiplash injury was 2.9%, for women 2.7% and for men 3.0%. There was a significant association between self reported whiplash injury and headache (OR = 2.1; 95% CI 1.8-2.4, and chronic MSCs (OR = 3.3; 95% CI 2.8-3.8, evident for all ten anatomical sites investigated. The association was most pronounced for those with a combination of headache and chronic MSC for both men (OR = 4.8; 95% CI 3.6-6.2 and women (OR = 5.2; 95% CI 3.7-7.1. Conclusions Subjects with self reported whiplash injury had significantly more headache and musculoskeletal complaints than those without, and may in part be due to selective reporting. The causal mechanism remains unclear and cannot be addressed in the present study design.

    This study examined male adolescents' self-report of rape of adolescent girls and the socio-demographic variables that correlated with self-report of rape. Descriptive-correlational design was used and the study was conducted in five public senior secondary schools in Ile-Ife, Nigeria. Three hundred and thirty-eight male adolescents participated in the study. A structured questionnaire was used to collect data. Findings from the study revealed the mean age of the adolescent males to be 16 years, with the majority (73%) of them in the middle adolescent stage. Six percent of the adolescent males reported they had raped an adolescent girl in the past. Among the boys who reported rape, 55% reported they had raped their sexual partners, and 55% reported they had perpetrated gang rape. Smoking (p = .0001), alcohol consumption (p = .001), and birth order (p = .006) predicted self-report of rape. The coefficient of birth order showed that odds of self-report of rape by first-born male increases by 6 times compared with other children. Study findings also provided evidence that adolescent males are moving from lone rape to gang rape in intimate partner relationships. Male adolescents are important group to target in rape prevention programs. © The Author(s) 2014.

  17. Self-reported empathy and neural activity during action imitation and observation in schizophrenia.

    Horan, William P; Iacoboni, Marco; Cross, Katy A; Korb, Alex; Lee, Junghee; Nori, Poorang; Quintana, Javier; Wynn, Jonathan K; Green, Michael F

    Although social cognitive impairments are key determinants of functional outcome in schizophrenia their neural bases are poorly understood. This study investigated neural activity during imitation and observation of finger movements and facial expressions in schizophrenia, and their correlates with self-reported empathy. 23 schizophrenia outpatients and 23 healthy controls were studied with functional magnetic resonance imaging (fMRI) while they imitated, executed, or simply observed finger movements and facial emotional expressions. Between-group activation differences, as well as relationships between activation and self-reported empathy, were evaluated. Both patients and controls similarly activated neural systems previously associated with these tasks. We found no significant between-group differences in task-related activations. There were, however, between-group differences in the correlation between self-reported empathy and right inferior frontal (pars opercularis) activity during observation of facial emotional expressions. As in previous studies, controls demonstrated a positive association between brain activity and empathy scores. In contrast, the pattern in the patient group reflected a negative association between brain activity and empathy. Although patients with schizophrenia demonstrated largely normal patterns of neural activation across the finger movement and facial expression tasks, they reported decreased self perceived empathy and failed to show the typical relationship between neural activity and self-reported empathy seen in controls. These findings suggest that patients show a disjunction between automatic neural responses to low level social cues and higher level, integrative social cognitive processes involved in self-perceived empathy.

    2008-07-01

    Full Text Available Abstract Background Surprisingly little is known about the frequency, stability, and correlates of school fear and truancy based on self-reported data of adolescents. Methods Self-reported school fear and truancy were studied in a total of N = 834 subjects of the community-based Zurich Adolescent Psychology and Psychopathology Study (ZAPPS at two times with an average age of thirteen and sixteen years. Group definitions were based on two behavioural items of the Youth Self-Report (YSR. Comparisons included a control group without indicators of school fear or truancy. The three groups were compared across questionnaires measuring emotional and behavioural problems, life-events, self-related cognitions, perceived parental behaviour, and perceived school environment. Results The frequency of self-reported school fear decreased over time (6.9 vs. 3.6% whereas there was an increase in truancy (5.0 vs. 18.4%. Subjects with school fear displayed a pattern of associated internalizing problems and truants were characterized by associated delinquent behaviour. Among other associated psychosocial features, the distress coming from the perceived school environment in students with school fear is most noteworthy. Conclusion These findings from a community study show that school fear and truancy are frequent and display different developmental trajectories. Furthermore, previous results are corroborated which are based on smaller and selected clinical samples indicating that the two groups display distinct types of school-related behaviour.

  10. Student Self-Reported Learning Outcomes of Field Trips: The pedagogical impact

    Lavie Alon, Nirit; Tal, Tali

    2015-05-01

    In this study, we used the classification and regression trees (CART) method to draw relationships between student self-reported learning outcomes in 26 field trips to natural environments and various characteristics of the field trip that include variables associated with preparation and pedagogy. We wished to examine the extent to which the preparation for the field trip, its connection to the school curriculum, and the pedagogies used, affect students' self-reported outcomes in three domains: cognitive, affective, and behavioral; and the extent the students' socioeconomic group and the guide's affiliation affect students' reported learning outcomes. Given that most of the field trips were guide-centered, the most important variable that affected the three domains of outcomes was the guide's storytelling. Other variables that showed relationships with self-reported outcomes were physical activity and making connections to everyday life-all of which we defined as pedagogical variables. We found no significant differences in student self-reported outcomes with respect to their socioeconomic group and the guide's organizational affiliation.

    2017-11-01

    Full Text Available ABSTRACT OBJECTIVE To estimate self-reported discrimination due to sexual orientation among men who have sex with men (MSM in Brazil and to analyze associated factors. METHODS A cross-sectional study of 3,859 MSM recruited in 2008–2009 with respondent driven sampling. Data collection conducted in health centers in 10 Brazilian cities. A face-to-face questionnaire was used and rapid HIV and syphilis tests conducted. Aggregated data were weighted and adjusted odds ratio estimated to measure the association between selected factors and self-reported discrimination due to sexual orientation. RESULTS The sample was predominantly young, eight plus years of schooling, pardo (brown, single, low-income, and identified themselves as gay or homosexual. The prevalence of self-reported discrimination due to sexual orientation was 27.7% (95%CI 26.2–29.1. Discrimination was independently associated with: age < 30 years, more years of schooling, community involvement and support, history of sexual and physical violence, suicidal thoughts, and unprotected receptive anal intercourse. CONCLUSIONS The prevalence of self-reported discrimination among MSM in Brazil is high. These results challenge the assumptions that MSM-specific prevention and support programs are not required or that health professionals do not need special training to address MSM needs.

  13. Self-report and longitudinal predictors of violence in Iraq and Afghanistan war era veterans.

    Elbogen, Eric B; Johnson, Sally C; Newton, Virginia M; Fuller, Sara; Wagner, H Ryan; Beckham, Jean C

    2013-10-01

    This study, using a longitudinal design, attempted to identify whether self-reported problems with violence were empirically associated with future violent behavior among Iraq and Afghanistan war veterans and whether and how collateral informant interviews enhanced the risk assessment process. Data were gathered from N = 300 participants (n = 150 dyads of Iraq and Afghanistan war veterans and family/friends). The veterans completed baseline and follow-up interviews 3 years later on average, and family/friends provided collateral data on dependent measures at follow-up. Analyses showed that aggression toward others at follow-up was associated with younger age, posttraumatic stress disorder, combat exposure, and a history of having witnessed parental violence growing up. Self-reported problems controlling violence at baseline had robust statistical power in predicting aggression toward others at follow-up. Collateral report enhanced detection of dependent variables: 20% of cases positive for violence toward others would have been missed relying only on self-report. The results identify a subset of Iraq and Afghanistan war veterans at higher risk for problematic postdeployment adjustment and indicate that the veterans' self-report of violence was useful in predicting future aggression. Underreporting of violence was not evidenced by most veterans but could be improved upon by obtaining collateral information.

  5. Relations Between Self-reported Executive Functioning and Speech Perception Skills in Adult Cochlear Implant Users.

    Moberly, Aaron C; Patel, Tirth R; Castellanos, Irina

    2018-02-01

    As a result of their hearing loss, adults with cochlear implants (CIs) would self-report poorer executive functioning (EF) skills than normal-hearing (NH) peers, and these EF skills would be associated with performance on speech recognition tasks. EF refers to a group of high order neurocognitive skills responsible for behavioral and emotional regulation during goal-directed activity, and EF has been found to be poorer in children with CIs than their NH age-matched peers. Moreover, there is increasing evidence that neurocognitive skills, including some EF skills, contribute to the ability to recognize speech through a CI. Thirty postlingually deafened adults with CIs and 42 age-matched NH adults were enrolled. Participants and their spouses or significant others (informants) completed well-validated self-reports or informant-reports of EF, the Behavior Rating Inventory of Executive Function - Adult (BRIEF-A). CI users' speech recognition skills were assessed in quiet using several measures of sentence recognition. NH peers were tested for recognition of noise-vocoded versions of the same speech stimuli. CI users self-reported difficulty on EF tasks of shifting and task monitoring. In CI users, measures of speech recognition correlated with several self-reported EF skills. The present findings provide further evidence that neurocognitive factors, including specific EF skills, may decline in association with hearing loss, and that some of these EF skills contribute to speech processing under degraded listening conditions.

    This study evaluates accuracy of self-reported weight in adolescent bariatric surgery patients. During follow-up visits, participants self-reported weight and had weight measured. The differences between self-reported and measured weights were analyzed from 60 participants. Participants were 70% (n = 42) female, 72% (n = 43) white, mean age of 20.8 years and a median body mass index of 36.6 kg/m 2 . At an average of 3.5 years following surgery, females underestimated weight (0.5 kg, range: -18.7 to 5.6 kg), while males overestimated (1.1 kg, range: -7.8 to 15.2 kg). Most (80%, n = 48) reported within 5 kg of measured weight. The majority of adolescents who previously underwent bariatric surgery reported reasonably accurate weights, but direction of misreporting varied by gender. Self-reported weights could be utilized when measured values are unavailable without markedly biasing the interpretation of outcomes.

    Most Alzheimer disease clinical trials that compare the use of health services rely on reports of caregivers. The goal of this study was to assess the accuracy of self-reports among older adults with Alzheimer disease and their caregiver proxy respondents. This issue is particularly relevant to Alzheimer disease clinical trials because inaccuracy can lead both to loss of power and increased bias in study outcomes. We compared respondent accuracy in reporting any use and in reporting the frequency of use with actual utilization data as documented in a comprehensive database. We next simulated the impact of underreporting and overreporting on sample size estimates and treatment effect bias for clinical trials comparing utilization between experimental groups. Respondents self-reports have a poor level of accuracy with κ-values often below 0.5. Respondents tend to underreport use even for rare events such as hospitalizations and nursing home stays. In analyses simulating underreporting and overreporting of varying magnitude, we found that errors in self-reports can increase the required sample size by 15% to 30%. In addition, bias in the reported treatment effect ranged from 3% to 18% due to both underreporting and overreporting errors. Use of self-report data in clinical trials of Alzheimer disease treatments may inflate sample size needs. Even when adequate power is achieved by increasing sample size, reporting errors can result in a biased estimate of the true effect size of the intervention.

  4. Self-reported and employer-recorded sickness absence in doctors.

    Murphy, I J

    2014-09-01

    Doctors' sickness absence reduces the quality and continuity of patient care and is financially costly. Doctors have lower rates of sickness absence than other healthcare workers. To compare self-reported with recorded sickness absence in doctors in a UK National Health Service hospital trust. A retrospective questionnaire study. The main outcome measures were self-reported and trust-recorded sickness absence episodes of 4 days or more in two consecutive 6-month periods. The response rate was 82% (607/736). Self-reported sickness absence rates were 1.2% compared with a rate of 0.6% from trust-recorded data. There were 38 matched pairs of self-reported (mean duration: 18 days, standard deviation: 22 days) and trust-recorded (mean duration: 10 days, standard deviation: 17 days) sickness absence episodes of 4 days or more in the 12 months studied. A matched pairs t-test determined that the difference between the two means was significant (t = 2.57, P sickness absence was significantly under-recorded in this study population. © The Author 2014.

    Most studies regarding xerostomia focus on elderly people. Therefore, the authors conducted a study of dental patients 18 years or older to determine the prevalence of self-reported xerostomia and associated risk factors. The authors sent a total of 2,200 questionnaires to four dental clinics to assess patients' self-reported xerostomia. They also collected sociodemographic data and information regarding personal behavior. They used logistic regression models to estimate odds ratios (OR) and 95 percent confidence intervals (CI) to explore the relationship between self-reported xerostomia and risk factors that reasonably might be expected to be associated with self-reported xerostomia. The overall prevalence of xerostomia in participants was 7 percent. Participants with burning-mouth sensations were associated with having higher odds of experiencing dry mouth (OR, 2.1; 95 percent CI, 0.9-5.2). Participants 51 years or older were significantly more likely to report having dry mouth than were younger participants (P xerostomia increased with increasing numbers of medications patients reported using. The authors found that medication use and age were highly significant risk factors for dental patients reporting xerostomia. Clinicians should interview their patients carefully regarding their use of medications and provide proper oral health care to improve xerostomia resulting from medication use.

  7. Changes in self-reported driving intentions and attitudes while learning to drive in Great Britain.

    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.

    Patients suffering from chronic obstructive pulmonary disease (COPD) experience problems in the performance of activities of daily living (ADL) tasks. The objective was to examine the self-reported quality of ADL task performance among COPD patients, and to investigate whether age, gender, and routine COPD characteristics correlate with the self-reported ADL ability. Eighty patients admitted to hospital with COPD exacerbations participated. In a cross-sectional study, the patients' self-reported ADL ability was assessed using the ADL-Interview (ADL-I) instrument. Data concerning age, gender, and routine COPD characteristics were drawn from the patients' medical records. The patients reported being inefficient to markedly inefficient when performing ADL tasks within the personal hygiene, toileting, dressing, household, mobility, and transportation domains. While more than 90% of the participants reported increased effort and/or fatigue when performing the ADL tasks, up to 88% of the participants relied on help from others in the performance of general household chores like cooking and shopping. Self-reported ADL ability did not correlate with age, gender, or routine COPD characteristics. Decreased quality of ADL task performance seemed to be extremely common among COPD patients. Therefore, addressing the problems in individually tailored pulmonary rehabilitation programmes may be advantageous.

    The objective of the present study was to assess self-reported periodontal screening questions, demographic characteristics, systemic medical conditions and tobacco use for predicting periodontal disease among individuals seeking dental therapy in a university dental clinic. In this retrospective study, a total of 4,890 randomly selected dental charts were evaluated from among patients who had attended the University of Minnesota School of Dentistry clinics for treatment. Radiographic bone loss measurements were utilized to assess the severity of periodontal disease. Demographic characteristics as well as medical history of the patients were also recorded. Five self-reported periodontal screening questions were included with the range of answers limited to Yes/No. Generalized logit models were used to assess the association between bone loss and the predictors. The sample mean age was 54.1 years and included 52.6% males and 14.9% smokers with a mean number of missing teeth of 3.5. Self-reported tooth mobility, history of "gum treatment" and the importance to keep the teeth as well as age, tobacco use and cancer were statistically significant (p brushing", gender, diabetes, anxiety and arthritis. Self-reported periodontal screening questions as well as demographic characteristics, smoking and systemic medical conditions were significant predictors of periodontal disease and they could be used as valid, economical and practical measures.

  14. Relationships between self-reported physical and mental health and intelligence performance across adulthood.

    Perlmutter, M; Nyquist, L

    1990-07-01

    One hundred and twenty-seven adults between 20 and 90 years of age were tested on the Wechsler Adult Intelligence Scale for their digit span memory (forward and backward), fluid intelligence (block design and digit symbol), and crystallized intelligence (vocabulary and information), as well as assessed for self-reported health (Cornell Medical Index, Zung Depression Scale, health habits, and self-ratings of physical and mental health). As expected, across the entire age range there was no correlation between age and digit span memory (r = .03), a strong negative correlation between age and fluid intelligence (r = -.78), and a modest positive correlation between age and crystallized intelligence (r = .27). In addition, older adults reported more physical (r = .36) and mental (r = .32) health problems than did younger adults. Of special interest was the finding that both self-reported physical and mental health accounted for significant variance in intelligence performance, particularly in older adults. Moreover, self-reported health accounted for a considerable portion of observed variance, even when age differences in self-reported health were statistically controlled.

    Full Text Available Objective: To assess whether self-reports of reproductive history and obstetric morbidity provide an accurate basis for clinical decision-making. Setting, participants and methods: Self-reports of maternal age and reproductive history, together with clinical measurements of five medical disorders, were abstracted from the obstetric notes of 517 mothers whose children were enrolled in the Birth to Ten study. These data were compared to self-reported information collected by interview during the Birth to Ten study. Findings: The reliability of self-reported age and gravidity was high (R=0.810-0.993, yet self-reports of previous miscarriages, terminations, premature- and stillbirths were only fairly reliable (Kappa=0.48-0.50. Self-reported diabetes and high blood pressure had specificities of more than 95% for glycosuria, hypertension and pre-eclampsia. However, the specificity of self-reported oedema for hypertensive disorders and the specificity of self-reported urinary tract infection for STD seropositivity were only around 65%. Conclusions: The modest reliability and limited validity of self-reported obstetric morbidity undermines the clinical utility of this information. Recommendations: These results strengthen the case for providing mothers with “Home-based Maternal Records” to facilitate access to accurate obstetric information during subsequent clinical consultations.
