  1. Rational Choice and Developmental Influences on Recidivism Among Adolescent Felony Offenders

    OpenAIRE

    Fagan, Jeffrey; Piquero, Alex R.

    2007-01-01

    Recent case law and social science both have claimed that the developmental limitations of adolescents affect their capacity for control and decision making with respect to crime, diminishing their culpability and reducing their exposure to punishment. Social science has focused on two concurrent adolescent developmental influences: the internalization of legal rules and norms that regulate social and antisocial behaviors, and the development of rationality to frame behavioral choices and dec...

    2011-01-01

    Previous studies of social influences on adolescent smoking have focused on peers and parents, using data collected prior the 1998 Master Settlement Agreement. This study used the 2004 wave of the National Youth Tobacco Survey to examine associations between peer smoking, smoking at home, tobacco-related media exposure, and smoking behavior during early and middle adolescence. Findings indicate that peer smoking and smoking at home remain strongly associated with current smoking among early and middle adolescents, controlling for gender, race/ethnicity and exposure to tobacco industry and anti-tobacco media. The magnitude of the association between peer smoking and current smoking decreases from early adolescence to middle adolescence while the association between smoking at home and current smoking is static across developmental stage. Exposure to tobacco-related media is associated with increased current and former smoking in both early and middle adolescence. PMID:20855170

    Little research has investigated differential genetic and environmental influences on different developmental trajectories of antisocial behavior. This study examined genetic and environmental influences on liabilities of being in life-course-persistent (LCP) and adolescent-limited (AL) type delinquent groups from adolescence to young adulthood while considering nonviolent and violent delinquency subtypes and gender differences. A genetically informative sample (n = 356, 15-16 years) from the first three waves of In-Home Interview of the National Longitudinal Study of Adolescent to Adult Health was used, with 94 monozygotic and 84 dizygotic pairs of same-sex twins (50% male). Biometric liability threshold models were fit and found that the male-specific LCP type class, chronic, showed more genetic influences, while the AL type classes, decliner and desister, showed more environmental influences. Genetic liability and shared environment both influence the persistence of antisocial behavior. The development of female antisocial behavior appears to be influenced more by shared environment.

    2009-01-01

    Full Text Available The authors define adolescence and developmental dysplasia of the hip (DDH. Special attention is paid to pathological findings characteristic of DDH in adolescence (unrecognized and untreated DDH; treated DDH, but non-terminated treatment; DDH diagnosed with delay, inadequately treated, with complications. The authors emphasise that DDH treatment has to be successfully terminated well before the adolescence; possibilities are explained on management modes at the time of adolescence, and possible persons guilty for the persistence of later hip problems are indicated. Based on the authors' experience and having in mind all surgical possibilities for the treatment (pelvic osteotomies, femoral osteotomies, trochanteroplasties, leg length equalization procedures the authors propose treatment protocols. The intention is to provide better treatment results and to prevent secondary hip arthrosis. Furthermore, how to improve the struggle against DDH is suggested.

    Recent research on risky decision-making in adults has shown that both the risk in potential outcomes and their valence (i.e., whether those outcomes involve gains or losses) exert dissociable influences on decisions. We hypothesised that the influences of these two crucial decision variables (risk and valence) on decision-making would vary developmentally during adolescence. We adapted a risk-taking paradigm that provides precise metrics for the impacts of risk and valence. Decision-making i...

    2014-01-01

    We examined the relationships between parent-adolescent discrepancies in perceived parenting characteristics (indexed by parental responsiveness, parental demandingness, and parental control) and adolescent developmental outcomes (indexed by achievement motivation and psychological competence) in poor families in Hong Kong. A sample of 275 intact families having at least one child aged 11-16 experiencing economic disadvantage were invited to participate in the study. Fathers and mothers completed the Parenting Style Scale and Chinese Parental Control Scale, and adolescents completed the Social-Oriented Achievement Motivation Scale and Chinese Positive Youth Development Scale in addition to paternal and maternal Parenting Style Scale and Chinese Parental Control Scale. Results indicated that parents and adolescents had different perceptions of parental responsiveness, parental demandingness, and paternal control, with adolescents generally perceived lower levels of parenting behaviors than did their parents. While father-adolescent discrepancy in perceived paternal responsiveness and mother-adolescent discrepancy in perceived maternal control negatively predicted adolescent achievement motivation, mother-adolescent discrepancy in perceptions of maternal responsiveness negatively predicted psychological competence in adolescents experiencing economic disadvantage. The present findings provided support that parent-child discrepancies in perceived parenting characteristics have negative impacts on the developmental outcomes of adolescents experiencing economic disadvantage. The present study addresses parent-child discrepancies in perceived parental behaviors as "legitimate" constructs, and explores their links with adolescent psychosocial development, which sheds light for researchers and clinical practitioners in helping the Chinese families experiencing economic disadvantage.

    2014-03-01

    Immigrant youth differ in their adaptation, which is judged on the basis of how well they deal with developmental and acculturative tasks. While immigrant adolescents are faced with the realities of 2 different cultures, they also have to master age-salient tasks, such as self-efficacy and identity development. To get a better insight into the interplay of developmental and acculturative tasks and their relationship with family functioning, we used 3-wave longitudinal data over a 2-year period from 13-year-old immigrant students (N = 609) in Athens, Greece. Cross-lagged models revealed that family functioning and acculturation were resources for the mastery of developmental tasks. Involvement in the host culture prospectively predicted self-efficacy beliefs, and involvement in the ethnic culture prospectively predicted ethnic identity. These effects increased over time. Family functioning prospectively predicted self-efficacy and ethnic identity. These effects decreased over time. The findings suggest that a well-functioning family, for early adolescents, and being involved in the host culture and in ethnic cultures, for middle adolescents, are particularly important resources to master the tasks of their developmental period. Our findings underscore the importance of developmentally sensitive approaches and the need to account for acculturative challenges in order to understand individual differences in immigrant youth adaptation.

    Normal brain maturational and developmental processes, together with plastic reorganization of the brain in response to experiential demands, contribute to the acquisition of improved capacities for self-regulation and impulse control during adolescence. The frontal lobe is a main focus for these developmental and plastic processes during the transition from adolescence into adulthood. Tourette syndrome (TS), defined as the chronic presence of motor and vocal tics, has been increasingly conceptualized as a disorder of impaired self-regulatory control. This disordered control is thought to give rise to semicompulsory urges to perform the movements that constitute simple tics, complex tics, or compulsions. Neuroimaging studies suggest that the expression of the genetic diathesis to TS is influenced by genetic and nongenetic factors affecting activity-dependent reorganization of neuroregulatory systems, thereby influencing the phenotype, illness severity, and adult outcome of tic disorders. Similar developmental processes during adolescence likely determine the phenotype and natural history of a broad range of other complex neuropsychiatric disorders of childhood onset, and they likely contribute to the acquisition of improved self-regulatory capacities that characterize normal adolescent development.

    2009-07-01

    Obesity results from a complex combination of factors that act at many stages throughout a person's life. Therefore, examining childhood nutrition and obesity from a developmental perspective is warranted. A developmental perspective recognizes the cumulative effects of factors that contribute to eating behavior and obesity, including biological and socioenvironmental factors that are relevant at different stages of development. A developmental perspective considers family, school, and community context. During gestation, risk factors for obesity include maternal diet, overweight, and smoking. In early childhood, feeding practices, taste acquisition, and eating in the absence of hunger must be considered. As children become more independent during middle childhood and adolescence, school nutrition, food marketing, and social networks become focal points for obesity prevention or intervention. Combining a multilevel approach with a developmental perspective can inform more effective and sustainable strategies for obesity prevention. PMID:19527595

    2016-01-01

    Social responsibility can be defined as a set of prosocial values representing personal commitments to contribute to community and society. Little is known about developmental change-and predictors of that change-in social responsibility during adolescence. The present study used an accelerated longitudinal research design to investigate the developmental trajectory of social responsibility values and ecological assets across family, school, community, and peer settings that predict these values. Data come from a 3-year study of 3,683 U.S. adolescents enrolled in upper-level elementary, middle, and high schools in rural, semiurban, and urban communities. Social responsibility values significantly decreased from age 9 to 16 before leveling off in later adolescence. Family compassion messages and democratic climate, school solidarity, community connectedness, and trusted friendship, positively predicted within-person change in adolescents' social responsibility values. These findings held after accounting for other individual-level and demographic factors and provide support for the role of ecological assets in adolescents' social responsibility development. In addition, fair society beliefs and volunteer experience had positive between- and within-person associations with social responsibility values. The manuscript discusses theoretical and practical implications of the conclusion that declines in ecological assets may partly explain age-related declines in social responsibility values.

    Background Few studies examining the genetic architecture of cigarette smoking have focused on adolescents or examined developmental changes in additive genetic, shared environment and unique environmental influences on liability to initiate cigarette smoking and quantity of cigarettes smoked. The aim of this study is to add to the literature on liability to initiate and use cigarettes during adolescence using a nationally representative sample. Method Data for this study came from adolescent and young adult twin pairs (ages 14-33) from the National Longitudinal Study of Adolescent to Adult Health. We ran a series of developmental causal-contingent-common pathway models to examine whether additive genetic, shared and unique environmental influences on liability to the initiation of cigarette use are shared with those on smoking quantity, and whether their contributions change across development. Results We found evidence for a developmental shift in genetic and shared environmental contributions to cigarette use. Early in adolescence genetic and environmental influences work independently on liability to cigarette smoking initiation and quantity of cigarettes smoked, but liability to these behaviors becomes correlated as individuals age into young adulthood. Conclusions These findings provide insight into the causal processes underlying the liability to smoke cigarettes. With age, there is greater overlap in the genetic and environmental factors that influence the initiation of cigarette smoking and quantity of cigarettes smoked. PMID:26227182

    This study used a person-centered approach to examine whether different developmental trajectories of boys' and girls' use of sexually explicit Internet material (SEIM) exist, which factors predict these trajectories, and whether sexual behavior develops differently for adolescents in these trajectories. A combination of latent class growth analysis on SEIM use and latent growth curve analysis on sexual behavior was used on four-wave longitudinal data of 787 eighth through tenth grade Dutch adolescents. Among boys, four SEIM use trajectories were identified, which were labeled Nonuse/Infrequent Use, Strongly Increasing Use, Occasional Use, and Decreasing Use. Among girls, a large Stable Nonuse/Infrequent Use and smaller Strongly Increasing Use and Stable Occasional Use trajectories were distinguished. Higher initial levels and/or stronger increases in SEIM use were predicted by demographic, social contextual, personal, and media use characteristics, including a stronger sexual interest, a higher degree of perceived realism regarding sexualized Internet content, and more permissive sexual attitudes. Moreover, initial levels of and, to some extent, developmental changes in sexual behavior varied for boys and girls in the different SEIM use trajectories. Whereas some adolescents showed concurrent low levels, or parallel strong increases in SEIM use and sexual behavior, a subgroup of boys decreased their SEIM use while increasing their sexual behavior.

    Full Text Available In the present article we review findings from an emerging body of research on attachment issues in adolescents with eating disorders from a developmental perspective. First, we will outline the crucial developmental changes in the attachment system and discuss how they might be related to the early onset of the disease. Then we will report on the major results from attachment studies using self-report and narrative instruments in that age group. Studies with a developmental approach on attachment will be analyzed in more detail. The high incidence of the unresolved attachment pattern in eating disorder samples is striking, especially for patients with anorexia nervosa. Interestingly, this predominance of the unresolved category was also found in their mothers. To date, these transgenerational aspects are still poorly understood and therefore represent an exciting research frontier. Future studies that include larger adolescent samples and provide a more detailed description including symptom severity and comorbidity would contribute to a better understanding of this complex and painful condition.

    During adolescence, peers take on increasing importance, while social skills are still developing. However, how emotions of peers influence social decisions during that age period is insufficiently known. We therefore examined the effects of three different emotional responses (anger, disappointment, happiness) on decisions about fairness in a sample of 156 adolescents aged 12-17 years. Participants received written emotional responses from peers in a version of the Dictator Game to a previous unfair offer. Adolescents reacted with more generous offers after disappointed reactions compared to angry and happy reactions. Furthermore, we found preliminary evidence for developmental differences over adolescence, since older adolescents differentiated more between the three emotions than younger adolescents. In addition, individual differences in social value orientation played a role in decisions after happy reactions of peers to a previous unfair offer, such that participants with a "proself" orientation made more unfair offers to happy peers than "prosocial" participants. Taken together, our findings demonstrate that adolescents take emotions of peers into account when making social decisions, while individual differences in social value orientation affect these decisions, and age seems to influence the nature of the reaction.

    Adolescence is an important period for the development of relationships between immigrants and non-immigrants, yet little is known about how problematic personality traits affect adolescents' relationships with and attitudes toward immigrants. This work identified the roles of intergroup relationships and one dimension of problematic personality traits, namely callous-unemotional traits, in the development of adolescents' tolerance and prejudice. Three annual measurements of a large community sample (N = 1,542) of non-immigrant adolescents (M age = 15.31 at first measurement; 50.2% girls) were used to show that tolerance and prejudice toward immigrants represent two dimensions with distinct developmental trajectories from early to late adolescence. Callous-unemotional traits predicted fewer decreases in prejudice toward immigrants, yet were not directly associated with tolerance. Intergroup friendships predicted stronger increases in tolerance, which, in turn, predicted decreases in prejudice toward immigrants. Thus, tolerance and prejudice toward immigrants seem to be differentially influenced by social experiences and problematic personality traits.

    A number of studies have associated impulsivity and sensation seeking with level of substance use and risk for developing a substance use disorder. These relationships may be particularly apparent during adolescence, when developmental changes in impulsivity and sensation seeking occur at the same time as increased opportunities for substance use. To examine this, the current study measured impulsivity and sensation seeking from pre-adolescence to mid-adolescence in a sample of youth, the majority of whom were identified as being at risk for developing a substance use disorder based on their family history of substance use disorders. Youth were separated into those who did (n=117) and did not (n=269) initiate substance use by mid-adolescence. Results showed that substance users were more impulsive and more sensation seeking during pre-adolescence, prior to any significant substance use, and that greater sensation seeking in pre-adolescence was related to heavier substance use by mid-adolescence. In addition, developmental trajectories for substance-using youth showed a greater increase in sensation seeking but a more modest decrease in impulsivity from pre-adolescence to mid-adolescence. Taken together, these results indicate that increased impulsivity and sensation seeking is apparent in adolescent substance users as early as pre-adolescence, that the difference between substance users and non-users becomes larger across early adolescence as their developmental trajectories diverge, and that greater sensation seeking in pre-adolescence may predict increased substance use by mid-adolescence.

    The portrayal of violence, sex, and drugs/alcohol in the media has been known to adversely affect the behavior of children and adolescents. There is a strong association between perceptions of media messages and observed behavior, especially with children. Lately, there has been more of a focus in the public health/medical field on media influences of youth and the role of the pediatrician and/or healthcare worker in addressing this area of growing concern. There is a need to explicitly explore the influences of media violence, sex, and drugs/alcohol on youth within the context of the Social Learning Theory. Implications of these influences are discussed, and recommendations for pediatricians and/or health care workers who interact with children and adolescents are described. Pediatricians and health care workers should incorporate media exposure probes into the developmental history of their patients and become knowledgeable about the effects of medial influences on youth.

    Baumeister's concept of the "new morbidity" pertains to the linkages between poverty, adolescent mothers, and a series of developmental delays in their children. Outlined are three possible causes of the mild mental retardation and learning disabilities that are found disproportionately among the offspring of adolescents. First, there may be a direct genetic transmission of mild mental retardation. Second, adolescent mothers are likely to have a lack of support from a social network, be unprepared cognitively and emotionally to assume responsibility for child rearing, and to look to an infant to meet their own needs. Third, the interaction of genetic and environmental deficits leads to a parenting style that deprives the child of stimulation that could potentially overcome these deficits. A secure mother-infant attachment relationship provides the foundation for the development of social, emotional, attentional, and self-regulatory processes. When this attachment relationship is insecure, as a result of the mother's unreadiness to parent, the child cannot proceed to exploration of the environment--a critical component of cognitive development. If the infant has a difficult temperament, the risk of physical and emotional abuse increases, further compromising the child's future development. By 3 years of age, many of these children are showing declines in mental functioning, delays in receptive language skills, and poor motor and social skills. Research is urged to identify events in this chain that can be targeted for early intervention. PMID:12319317

    Aggression-related problems such as assault and homicide among adolescents and young adults exact considerable social and economic costs. Although progress has been made, additional research is needed to help combat this persistent problem. Several lines of research indicate that parental hostility is an especially potent predictor of adolescent aggression, although most longitudinal research has focused on clarifying the direction of effects. In this study, we used longitudinal data from the PROSPER project (N = 580; 54.8% female), a primarily rural Caucasian preventative intervention sample, to examine developmental change in early- to mid-adolescent aggressive behavior problems (age 11-16 years). In addition, we examined maternal hostility as a predictor of developmental change in aggression and the PROSPER preventative intervention, designed to reduce substance use and aggression, as a potential influence on this association. Lastly, several studies indicate that variation in the DRD4 7-repeat gene moderates both parenting and intervention influences on externalizing behavior. Accordingly, we examined the potential moderating role of DRD4. As hypothesized, there was a significant maternal hostility by intervention interaction indicating that the intervention reduced the negative impact of maternal hostility on adolescent change in aggressive behavior problems. DRD4 7-repeat status (7+ vs. 7-) further conditioned this association whereby control group 7+ adolescents with hostile mothers showed increasing aggressive behavior problems. In contrast, aggression decreased for 7+ adolescents with similarly hostile mothers in the intervention. Implications for prevention are discussed as well as current perspectives in candidate gene-by-environment interaction research.

    Several national reports and many individuals in the clinical oncology community have defined the adolescent and young adult (AYA) cancer population as individuals diagnosed between the ages of 15 and 39. However, neuroscience and developmental research have identified important decision-making skills (e.g., information processing, reasoning, emotion regulation) that are not fully developed during adolescence, making general, AYA-focused doctor-patient interaction guidelines potentially questionable for the adolescent cancer population. Most studies include adolescents in samples of pediatric cancer patients or include adolescents in samples of young adult cancer patients, but studies rarely consider adolescent cancer patients as a distinct, developmentally unique group. A systematic literature review was undertaken in October 2014 to begin to understand what is known about the doctor-patient relationship and communication preferences within adolescent oncology. From the 25 included studies, three important conclusions emerged: (1) discrepancies among adolescent patients, parents, and providers about the desired extent of involvement in treatment-related decisions; (2) patient desire for developmentally and culturally appropriate information provision; and (3) the desire and preference for how information is delivered, with recognition that these preferences may change with age. There was some variation in themes by study design, with studies directly observing medical consultations reporting less adolescent involvement in discussions than studies that surveyed doctors. The results of this review support the need for developmentally focused research and clinical guidelines that emphasize the experience of adolescent cancer patients separate from their older and younger counterparts.

    Food choices established during childhood and adolescence tend to persist into adulthood with consequences for long-term health. Yet, to date, relatively little research has examined factors that influence the food choices of children and adolescents from their perspectives. In this article, previous research is extended by examining developmental differences between children's and adolescents' perceptions of factors influencing their food choices. Focus group discussions were conducted with 29 young people from three age groups (9-10, 13-14 and 16-18 years). An inductive thematic analysis identified three key factors as influencing food choices. These factors included intra-individual factors: the link between food preferences and awareness of healthy eating; intra-familial factors: the role of the home food environment; and extra-familial factors: eating away from the home. Findings indicate that there were developmental differences between children's and adolescents' perceptions of factors influencing food choice. Among adolescents, parental control began to diminish and adolescents exercised increased autonomy over their food choices compared with children. To develop effective nutrition interventions, it is important to gather child and adolescent input regarding factors perceived as influencing their food choices. PMID:20382978

    Two bereavement-related disorders are proposed for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V): Adjustment Disorder Related to Bereavement, to be located in the main body of the text as an official diagnostic entity; and Bereavement-Related Disorder, including a Traumatic Death Specifier, to be located in the Appendix as an invitation for further research. These diagnoses currently do not include developmentally informed criteria, despite the importance of developmental processes in the ways children and adolescents grieve. In this article, we draw upon a selective review of the empirical literature and expert clinical knowledge to recommend developmentally informed modifications and specifiers of the proposed criteria for both bereavement disorders and strategies to improve future research. This article is derived from an invited report submitted to the DSM-V Posttraumatic Stress Disorder, Trauma, and Dissociative Disorders Sub-Work Group, and suggested modifications have received preliminary approval to be incorporated into the DSM-V at the time of this writing. Adoption of these proposals will have far-reaching consequences, given that DSM-V criteria will influence both critical treatment choices for bereaved youth and the next generation of research studies.

    Researchers have examined the predictors of adolescent gang membership, finding significant factors in the neighborhood, family, school, peers, and individual domains. However, little is known about whether risk and protective factors differ in predictive salience at different developmental periods. The present study examines predictors of joining a gang, tests whether these factors have different effects at different ages, and whether they differ by gender using the Seattle Social Development Project (SSDP) sample (n=808). By age 19, 173 participants had joined a gang. Using survival analysis, results showed that unique predictors of gang membership onset included living with a gang member, antisocial neighborhood, and antisocial peer influences in the previous year. No time or gender interactions with predictors were statistically significant.

    Adolescent risk-taking behavior needs to be understood in the context of contemporary youth culture and normal development. To facilitate passage through adolescence, parents should sustain a climate of control and commitment balanced by respect for the adolescent's increased capacity for self-regulation. (Author)

  1. How children and adolescents spend time across the world: work, play, and developmental opportunities.

    The authors review studies on time use of children and adolescents around the world and discuss developmental implications of population differences. Industrialization and schooling are linked to dramatic declines in time spent on household and wage labor. This labor is often unchallenging, sometimes hazardous; developmental benefits often do not increase above a limited number of hours; hence, reduction in these activities opens time for activities that may be more developmentally beneficial. Adolescents in East Asian postindustrial societies spend this freed-up time in schoolwork, a use associated with lower intrinsic motivation but high achievement and economic productivity. Adolescents in North America spend more time in leisure, associated with greater self-direction but of an uncertain relation to development. Age, gender, and socioeconomic differences in activities and with whom time is spent are also considered. PMID:10589300

  2. Adolescents' resilience as a self-regulatory process: promising themes for linking intervention with developmental science.

    2006-12-01

    This chapter focuses on the concept of self-regulation as a measure of resilience in children and adolescents. Developmental psychology and neuroscience are converging on the role of attention control as a central ability underlying self-regulation. We collected measures of adolescent attention control from parents and youth, and a measure of self-regulation from teachers. The measures of effortful attention correlated highly with teacher ratings of self-regulation. The composite measure of self-regulation (youth, parent, teacher report) was found to moderate the impact of peer deviance on adolescent antisocial behavior, as well as stress on adolescent depression. These findings suggest that self-regulation is a promising index of adolescent resilience. The construct of self-regulation also provides an excellent target for strategies aimed to improve child and adolescent adjustment in problematic environments and stressful circumstances.

    Adolescent health behaviors, especially health risk behaviors, have previously been linked to distal (i.e., family economic pressure) and proximal (i.e., parental support) contributors. However, few studies have examined both types of contributors along with considering health promoting and health risk behaviors separately. The present study investigated the influences of family economic hardship, supportive parenting as conceptualized by self-determination theory, and individual psychosocial and behavioral characteristics (i.e., mastery and delinquency, respectively) on adolescents' health promoting and health risk behaviors. We used structural equation modeling to analyze longitudinal data from a sample of Caucasian adolescent children and their mothers and fathers (N = 407, 54 % female) to examine direct and indirect effects, as well as gender symmetry and asymmetry. Findings suggest that family economic pressure contributed to adolescent mastery and delinquency through supportive parenting. Further, supportive parenting indirectly affected adolescent health risk behaviors only through delinquency, whereas supportive parenting indirectly influenced health promoting behaviors only through mastery, suggesting different developmental pathways for adolescent health risk and health promoting behaviors. Testing for gender symmetry of the full model showed that maternal and paternal parenting contributed to females' health risk behaviors directly, while maternal and paternal parenting contributed to males' health risk behaviors through delinquency. Gender symmetry was largely unsupported. The study highlights key direct and indirect pathways to adolescent health risk and health promoting behaviors within a family stress model and self-determination theory framework, and also highlights important gender differences in these developmental pathways.

    Children of adolescent mothers are at risk for developmental delays. Less is known about the heterogeneity in these children's developmental trajectories, and factors associated with different patterns of development. This longitudinal study used latent class growth analysis (LCGA) to identify distinct trajectories in children of Mexican-origin adolescent mothers (N = 204). Three distinct groups emerged: (a) a Delayed/Decreasing Functioning group, (b) an At-Risk/Recovering Functioning group, and (c) a Normative/Stable Functioning group. Children with Delayed/Decreasing Functioning were more likely than those with Normative/Stable Functioning to have families with lower income, fewer learning materials at home, and adolescent mothers with more depressive symptoms and greater coparental conflict with adolescents' mother figures. The results contribute to knowledge about factors associated with risk of delay. PMID:27351701

  12. Adolescent-Onset Depression: Are Obesity and Inflammation Developmental Mechanisms or Outcomes?

    Depression often has its first onset during adolescence and is associated with obesity. Furthermore, inflammatory processes have been implicated in both depression and obesity, although research amongst adolescents is limited. This review explores associations between depression and obesity, depression and inflammation, and obesity and inflammation from a developmental perspective. The temporal relations between these factors are examined to explore whether obesity and elevated inflammation act as either risk factors for, or outcomes of, adolescent-onset depression. Sex differences in these processes are also summarized. We propose a model whereby increases in sex hormones during puberty increase risk for depression for females, which can lead to obesity, which in turn increases levels of inflammation. Importantly, this model suggests that inflammation and obesity are outcomes of adolescent depression, rather than initial contributing causes. Further research on biological and psychosocial effects of sex hormones is needed, as is longitudinal research with children and adolescents.

    2010-07-01

    The nature of immature reward processing and the influence of rewards on basic elements of cognitive control during adolescence are currently not well understood. Here, during functional magnetic resonance imaging, healthy adolescents and adults performed a modified antisaccade task in which trial-by-trial reward contingencies were manipulated. The use of a novel fast, event-related design enabled developmental differences in brain function underlying temporally distinct stages of reward processing and response inhibition to be assessed. Reward trials compared with neutral trials resulted in faster correct inhibitory responses across ages and in fewer inhibitory errors in adolescents. During reward trials, the blood oxygen level-dependent signal was attenuated in the ventral striatum in adolescents during cue assessment, then overactive during response preparation, suggesting limitations during adolescence in reward assessment and heightened reactivity in anticipation of reward compared with adults. Importantly, heightened activity in the frontal cortex along the precentral sulcus was also observed in adolescents during reward-trial response preparation, suggesting reward modulation of oculomotor control regions supporting correct inhibitory responding. Collectively, this work characterizes specific immaturities in adolescent brain systems that support reward processing and describes the influence of reward on inhibitory control. In sum, our findings suggest mechanisms that may underlie adolescents' vulnerability to poor decision-making and risk-taking behavior. PMID:19875675

    1994-08-01

    This article examines the interrelations of personal and social factors in fostering longitudinal patterns of depressive symptoms, using 3 waves of data from high school students in the Boston area. Previously depressed and nondepressed youths differed markedly in their emotional responsiveness to family and friend relations. Chronically depressed youths were unresponsive to family problems, but were highly reactive to peer relations. Among previously asymptomatic youths, family relations exerted greater effects on depressed mood than relations with peers. Further analyses suggest a process through which chronic family turmoil shapes long-term mental health while also intensifying the distancing from family and investment in peer relationships that typically occurs in adolescence. Findings illustrate the importance of modeling transactions between personal and environmental factors in research on adolescent mental health and development. PMID:7932062

    Tan, Tony X; Rice, Jessica L; Mahoney, E Emily

    2015-01-01

    Internationally adopted (IA) children often have delays at adoption and undergo massive catch-up after adoption. Before achieving developmental catch-up, however, delays at adoption present a risk for IA children's adjustment, but it remains unknown whether such delays foreshadow IA children's outcomes after catch-up development has completed or ceased. In the current analysis, we utilized menarche as a practical marker to indicate the cessation of developmental catch-up. We investigated how delays at arrival predicted long-term outcomes in 132 postmenarcheal teens (M = 14.2 years, SD = 1.7) who were adopted from China at 16.6 months (SD = 17.1). In 2005, adoptive parents provided data of medical evaluation results on their children's delay status in gross motor skills, fine motor skills, social development, emotional development, and cognitive development. Six years later in 2011, data on parent-child relationship quality were collected from parents, and data on the adoptees' academic competence and internalizing problems were also collected from both parents and adoptees. We found that gross motor delay at arrival predicted academic performance (parent-report: b = -.34, p < .01) and internalizing problems (self-report: b = .26, p < .05; parent-report: b = .33, p < .01). Other delays were not significant in predicting any of the outcomes. The impact of early nutritional deprivation on gross motor development was discussed.

    Research has shown that physical exercise enhances cognitive performance in individuals with intact cognition as well as in individuals diagnosed with intellectual and developmental disabilities. Although well identified in the field of health (for example, the transient hypofrontality theory), the underlying neurocognitive processes in intellectual and developmental disabilities remain widely unclear and thus characterize the primary aim of this research. Eleven adolescents with intellectual and developmental disabilities performed moderate cycling exercise and common relaxation. Cross-over designed, both 10-min meetings were randomly allocated at the same time of day with 24-h time lags in between. Conditions were embedded in ability-modified cognitive performance (decision-making processes). Participants' reaction times and their equivalent neurophysiological parameters were recorded using standard EEG and analyzed (spatial activity, N2). Exercise revealed a decrease in frontal electrocortical activity, most pronounced in the medial frontal gyrus (10%). To that effect, reaction time (pcognitive performance for adolescents with intellectual and developmental disabilities; further research is needed to explore possible future effects on enhancing neurocognitive development.

    Adolescents undergo critical developmental transformations that increase the salience of peer influence. Peer interactions (platonic and romantic) have been found to have both a positive and negative influence on adolescent attitudes and behaviors related to romantic relationships and sexual behavior. This study used qualitative methodology to explore how peers influence romantic and sexual behavior. Forty adolescents participated in individual semi-structured interviews. All interviews were audio recorded and transcribed, and analyzed using a modified grounded theory approach. The concept of peer influence on romantic relationships and sexual behavior emerged as a key theme. Youth described that platonic peers (friends) influenced their relationships and sexual behavior including pressuring friends into relationships, establishing relationships as currency for popularity and social status, and creating relationship norm and expectations. Romantic peers also motivated relationship and sexual behavior as youth described engaging in behavior to avoid hurting and successfully pleasing their partners. Future research should explore multiple types of peer influence in order to better inform interventions to improve the quality of adolescents' romantic and sexual relationships.

    The mission of schools has broadened beyond academics to address risk behaviors such as substance use, delinquency, and socialization problems. With an estimated 3.4% of all U.S. youth being homeschooled, this study examines how U.S. homeschoolers fare on these outcomes given their lack of access to these school services. Adolescents (ages 12-17) from the 2002 through 2011 National Surveys of Drug Use and Health (NSDUH) were divided based on school status (home vs. traditional schooling) and religious affiliation (stronger vs. weaker). Controlling for demographic differences, homeschoolers with weaker religious ties were three times more likely to report being behind their expected grade level and two and a half times more likely to report no extracurricular activities in the prior year than their traditionally schooled counterparts. This group was also more likely to report lax parental attitudes toward substance use. Findings suggest homeschoolers with weaker religious ties represent an at-risk group. PMID:24793392

    Objective Mean-levels of thin-ideal internalization increase during adolescence and pubertal development, but it is unknown whether these phenotypic changes correspond to developmental changes in etiological (i.e., genetic and environmental) risk. Given the limited knowledge on risk for thin-ideal internalization, research is needed to guide the identification of specific types of risk factors during critical developmental periods. The present twin study examined genetic and environmental influences on thin-ideal internalization across adolescent and pubertal development. Method Participants were 1,064 female twins (ages 8–25 years) from the Michigan State University Twin Registry. Thin-ideal internalization and pubertal development were assessed using self-report questionnaires. Twin moderation models were used to examine if age and/or pubertal development moderate genetic and environmental influences on thin-ideal internalization. Results Phenotypic analyses indicated significant increases in thin-ideal internalization across age and pubertal development. Twin models suggested no significant differences in etiologic effects across development. Nonshared environmental influences were most important in the etiology of thin-ideal internalization, with genetic, shared environmental, and nonshared environmental accounting for approximately 8%, 15%, and 72%, respectively, of the total variance. Discussion Despite mean-level increases in thin-ideal internalization across development, the relative influence of genetic versus environmental risk did not differ significantly across age or pubertal groups. The majority of variance in thin-ideal internalization was accounted for by environmental factors, suggesting that mean-level increases in thin-ideal internalization may reflect increases in the magnitude/strength of environmental risk across this period. Replication is needed, particularly with longitudinal designs that assess thin-ideal internalization across key

    The present study examined associations between parenting and perceived health in adolescents with congenital heart disease (CHD) using a longitudinal trajectory approach. Adolescents with CHD were selected from the database of pediatric and congenital cardiology of the University Hospitals Leuven. A total of 429 adolescents (M age = 16 at T1) participated in the present study, comprising four measurement waves spanning approximately 3 years. Latent class growth analysis was used to identify trajectory classes of parenting and perceived health. Whereas adolescents from democratic households reported the most favorable health outcomes, adolescents from authoritarian, overprotective, and psychologically controlling families (all characterized by relatively high levels of psychological control) showed an increased risk for poor perceived health over time. Hence, the present study found substantial developmental associations between parenting and perceived health in adolescents with CHD. Future research should investigate whether working on the parent-adolescent relationship can foster patients' health. PMID:24819301

    Misperceptions of peer substance use (SU) are believed to be a robust correlate of adolescent SU; however, perceived peer SU is biased in the direction of an adolescent's own SU raising questions about the validity of perceived peer SU (social norms; Henry, Kobus, & Schoeny, 2011). In addition, social norm theories emphasize inaccurate perceptions of peer SU while other theories emphasize actual peer behavior and selection of friends as motivators of adolescent SU. Furthermore, no theories consider the role of accurate perceptions, suggesting the need to more carefully consider the coevolution of perceived peer norms, actual peer behavior, and adolescent SU. To do this, we modeled the latent structure of accurate and inaccurate perceptions of peer SU while including an adolescent's own SU using latent class analysis and tested the natural evolution of the classes using latent transition analysis. The design included 3 annual assessments of peer and perceptions of peer SU and 6 assessments of adolescent SU (N = 765; age = 10-13 at Wave 1; female = 53%). Latent class analysis findings largely replicated Henry et al. (2011), suggesting that misperceptions of peer SU were biased by an adolescent's own SU. We also found 3 distinct pathways to a high risk class that predicted high levels of later adolescent SU, 2 in which adolescent and perceived peer SU preceded peer SU (age = 10-12 and 12-14) and another in which peer SU preceded adolescent SU and perceptions of peer SU (age = 12-14). Implications for peer influence theories are discussed. (PsycINFO Database Record PMID:27214169

    A focus group study was conducted to develop an understanding of the experiences of mothers who are trying to balance employment with caring for an adolescent with developmental disabilities. Mothers reported facing considerable difficulties balancing work and caregiving responsibilities because support services rapidly declined when their child reached adolescence. Service cuts were related to the fact that adolescents are expected to be able to care for themselves, despite the fact that for many adolescents with disabilities, this is not possible. The mothers also reported that the preponderance of the responsibility for arranging care for their children was theirs and was not shouldered by their partners. Policy implications are discussed.

    Full Text Available We investigated the radiologic developmental process of the arcuate fasciculus (AF using subcomponent diffusion tensor imaging (DTI analysis in typically developing volunteers. DTI data were acquired from 96 consecutive typically developing children, aged 0-14 years. AF subcomponents, including the posterior, anterior, and direct AF tracts were analyzed. Success rates of analysis (AR and fractional anisotropy (FA values of each subcomponent tract were measured and compared. AR of all subcomponent tracts, except the posterior, showed a significant increase with aging (P < 0.05. Subcomponent tracts had a specific developmental sequence: First, the posterior AF tract, second, the anterior AF tract, and last, the direct AF tract in identical hemispheres. FA values of all subcomponent tracts, except right direct AF tract, showed correlation with subject′s age (P < 0.05. Increased AR and FA values were observed in female subjects in young age (0-2 years group compared with males (P < 0.05. The direct AF tract showed leftward hemispheric asymmetry and this tendency showed greater consolidation in older age (3-14 years groups (P < 0.05. These findings demonstrated the radiologic developmental patterns of the AF from infancy to adolescence using subcomponent DTI analysis. The AF showed a specific developmental sequence, sex difference in younger age, and hemispheric asymmetry in older age.

    This research examines the positive aspects of coping experienced by 270 mothers of adolescent children with and without a developmental disability in the Bedouin community. The mothers completed the Sociodemographic Data Questionnaire, the Grandparents Functional Support Assessment, the Gratitude Questionnaire, and the Posttraumatic Growth Inventory. Mothers of adolescent children with developmental disability reported higher levels of social support, gratitude, and personal growth than did mothers of adolescent children without developmental disability. Additionally, mothers demonstrated a higher level of gratitude toward their spouse's parents. Positive correlation was also found between gratitude and personal growth and between gratitude and support from the husband's parents. The findings highlight the important need to develop awareness and culturally appropriate intervention programs based on these positive aspects, to enhance these mothers' coping abilities.

    This study examined longitudinal pathways through three domains of adaptation from ages 4-5 to 14-15 (internalizing problems, externalizing problems, and academic competence) towards depressive symptoms at age 16-17. Participants were 6425 Canadian children followed bi-annually as part of the National Longitudinal Study of Children and Youth. Within-domain (i.e., stability) effects were moderate in strength. We found longitudinal cross-domain effects across one time point (i.e., one-lag cascades) between internalizing and externalizing in early childhood (positive associations), and between academic competence and externalizing in later childhood and adolescence (negative associations). We also found cascade effects over multiple time points (i.e., multi-lag cascades); lower academic competence at age 4-5 and greater internalizing at age 6-7 predicted greater age 12-13 externalizing, and greater age 6-7 externalizing predicted greater age 16-17 depression. Important pathways towards adolescent depression include a stability path through childhood and adolescent internalizing, as well as a number of potential paths involving all domains of adaptation, highlighting the multifactorial nature of adolescent depression.

    2014-12-01

    Sexual selection is often assumed to be strong and consistent, yet increasing research shows it can fluctuate over space and time. Few experimental studies have examined changes in sexual selection in response to natural environmental variation. Here, we use a difference in resource quality to test for the influence of past environmental conditions and current environmental conditions on male and female mate choice and resulting selection gradients for leaf-footed cactus bugs, Narnia femorata. We raised juveniles on natural high- and low-quality diets, cactus pads with and without ripe cactus fruits. New adults were again assigned a cactus pad with or without fruit, paired with a potential mate, and observed for mating behaviors. We found developmental and adult encounter environments affected mating decisions and the resulting patterns of sexual selection for both males and females. Males were not choosy in the low-quality encounter environment, cactus without fruit, but they avoided mating with small females in the high-quality encounter environment. Females were choosy in both encounter environments, avoiding mating with small males. However, they were the choosiest when they were in the low-quality encounter environment. Female mate choice was also context dependent by male developmental environment. Females were more likely to mate with males that had developed on cactus with fruit when they were currently in the cactus with fruit environment. This pattern disappeared when females were in the cactus without fruit environment. Altogether, these results experimentally demonstrate context-dependent mate choice by both males and females. Furthermore, we demonstrate that simple, seasonal changes in resources can lead to fluctuations in sexual selection.

    2016-02-01

    We examined how genotype-environment correlation processes differ as a function of adolescent age. We tested whether adolescent age moderates genetic and environmental influences on positivity and negativity in mother-adolescent and father-adolescent relationships using parallel samples of twin parents from the Twin and Offspring Study in Sweden and twin/sibling adolescents from the Nonshared Environment in Adolescent Development Study. We inferred differences in the role of passive and nonpassive genotype-environment correlation based on biometric moderation findings. The findings indicated that nonpassive gene-environment correlation played a stronger role for positivity in mother- and father-adolescent relationships in families with older adolescents than in families with younger adolescents, and that passive gene-environment correlation played a stronger role for positivity in the mother-adolescent relationship in families with younger adolescents than in families with older adolescents. Implications of these findings for the timing and targeting of interventions on family relationships are discussed.

    This longitudinal study investigated the timing effect of bullying on developmental trajectories of externalizing behaviors from middle childhood to adolescence. We focused on the relation of (a) only an early experience of bullying (i.e., desisters) to subsequent externalizing behaviors in adolescence and (b) only a late experience of bullying (i.e., late-onsetters) to the concurrent externalizing behaviors in adolescence. Their trajectories of externalizing behaviors were compared with the persisters and to the non-experience group. Individual growth curve modeling was conducted using 440 child-mother dyads from the Springfield Child Development Project, a community-representative, longitudinal study over a 6-year period that included four time interviews. We modeled the changes in child aggression and delinquency from 7 to 19 years of age as a function of bully status group. Results indicated that the levels of aggression and delinquency for the desisters decreased over time (with the cessation of bullying in adolescence) and were significantly lower than those of the persisters and similar to those of the non-involved group at the end of the trajectory (cessation effect). For the late-onsetters, the level of delinquency increased over time (with the onset of bullying behaviors in adolescence) and were significantly higher than those of the non-involved group and similar to those of the persisters at the end of the trajectory (onset effect). The aggression for the late-onsetters, however, did not support the onset effect. This study implies that we need to pay more attention to intervening for late-onset. PMID:25900912

  6. Thicker temporal cortex associates with a developmental trajectory for psychopathic traits in adolescents.

    Directory of Open Access Journals (Sweden)

    Yaling Yang

    Full Text Available Psychopathy is a clinical condition characterized by a failure in normal social interaction and morality. Recent studies have begun to reveal brain structural abnormalities associated with psychopathic tendencies in children. However, little is known about whether variations in brain morphology are linked to the developmental trajectory of psychopathic traits over time. In this study, structural magnetic resonance imaging (sMRI data from 108 14-year-old adolescents with no history of substance abuse (54 males and 54 females were examined to detect cortical thickness variations associated with psychopathic traits and individual rates of change in psychopathic traits from ages 9 to 18. We found cortical thickness abnormalities to correlate with psychopathic traits both cross-sectionally and longitudinally. Specifically, at age 14, higher psychopathic scores were correlated with thinner cortex in the middle frontal gyrus, particularly in females, and thicker cortex in the superior temporal gyrus, middle temporal gyrus, and parahippocampal gyrus, particularly in males. Longitudinally, individual rates of change in psychopathic tendency over time were correlated with thicker cortex in the superior temporal gyrus, middle temporal gyrus, inferior temporal gyrus, parahippocampal gyrus, and posterior cingulate gyrus, particularly in males. Findings suggest that abnormal cortical thickness may reflect a delay in brain maturation, resulting in disturbances in frontal and temporal functioning such as impulsivity, sensation-seeking, and emotional dysregulation in adolescents. Thus, findings provide initial evidence supporting that abnormal cortical thickness may serve as a biomarker for the development of psychopathic propensity in adolescents.

    This longitudinal study examined the developmental trajectories of prosocial behavior and related predictors among adolescents exposed to the 2008 Wenchuan earthquake. At 6-, 18-, and 30-months postearthquake, we followed a sample of 1,573 adolescents. Self-report measures were used to assess earthquake exposure, postearthquake negative life events, prosocial behavior, symptoms of posttraumatic stress disorder, depression, anxiety, social support, and coping style. Data were analyzed using growth mixture modeling and multinomial logistic regressions. Four trajectories of postearthquake prosocial behavior were identified in the sample: (a) high/enhancing (35.0%), (b) high/stable (29.4%), (c) low/declining (33.6%), and (d) low/steeply declining (2.0%). Female gender, more social support, and greater positive coping were significant factors related to a higher probability of developing the high/enhancing trajectory. These findings may be helpful for us to identify adolescents with poor prosocial behavior after exposure to earthquakes so as to provide them with appropriate intervention. PMID:26855079

    Full Text Available Background: The assessment of therapeutic adherence and competence is often neglected in psychotherapy research, particularly in children and adolescents; however, both variables are crucial for the interpretation of treatment effects. Objective: Our aim was to develop, adapt, and pilot two scales to assess therapeutic adherence and competence in a recent innovative program, Developmentally Adapted Cognitive Processing Therapy (D-CPT, for adolescents suffering from posttraumatic stress disorder (PTSD after childhood abuse. Method: Two independent raters assessed 30 randomly selected sessions involving 12 D-CPT patients (age 13–20 years, M age=16.75, 91.67% female treated by 11 therapists within the pilot phase of a multicenter study. Results: Three experts confirmed the relevance and appropriateness of each item. All items and total scores for adherence (intraclass correlation coefficients [ICC]=0.76–1.00 and competence (ICC=0.78–0.98 yielded good to excellent inter-rater reliability. Cronbach's alpha was 0.59 for the adherence scale and 0.96 for the competence scale. Conclusions: The scales reliably assess adherence and competence in D-CPT for adolescent PTSD patients. The ratings can be helpful in the interpretation of treatment effects, the assessment of mediator variables, and the identification and training of therapeutic skills that are central to achieving good treatment outcomes. Both adherence and competence will be assessed as possible predictor variables for treatment success in future D-CPT trials.

    The current study examined multilevel risk factors and developmental assets on longitudinal trajectories of aggressive behavior in a diverse sample of rural adolescents. Using ecological and social capital theories, we explored the impact of positive and negative proximal processes, social capital, and contextual characteristics (i.e., school and neighborhood) on adolescent aggression. Data came from the Rural Adaptation Project, which is a 5-year longitudinal panel study of more than 4,000 middle and high school students from 40 public schools in two rural, low income counties in North Carolina. A three-level HLM model (N = 4,056 at Wave 1, 4,251 at Wave 2, and 4,256 at Wave 3) was estimated to predict factors affecting the change trajectories of aggression. Results indicated that negative proximal processes in the form of parent-adolescent conflict, friend rejection, peer pressure, delinquent friends, and school hassles were significant predictors of aggression. In addition, social capital in the form of ethnic identity, religious orientation, and school satisfaction served as buffers against aggression. Negative proximal processes were more salient predictors than positive proximal processes. School and neighborhood characteristics had a minimal impact on aggression. Overall, rates of aggression did not change significantly over the 3-year study window. Findings highlight the need to intervene in order to decrease negative interactions in the peer and parent domains. PMID:26349636

    2014-08-01

    Most obstetrician-gynecologists will encounter adolescents with disabilities in their practice, because developmental and physical disabilities are common in young patients (8.4%). Reproductive health issues such as puberty, sexuality, and menstruation can be more complicated for teenagers with disabilities and their families as a result of concerns surrounding menstrual hygiene, abuse risk, vulnerability, changes in seizure pattern, and altered mood. Teenagers with disabilities have gynecologic health care needs similar to those of their peers as well as unique needs related to their physical and cognitive issues. The gynecologic health visit for a teenager with disabilities should include an evaluation of the teenager's reproductive knowledge as well as an assessment of her abuse and coercion risk and her ability to consent to sexual activity. The menstrual history is focused on the effects of menstrual cycles on her daily life. Diagnostic testing is not different from other adolescents. Hormonal treatment is often requested by the patient and her family to alleviate abnormal bleeding, cyclic mood changes, dysmenorrhea, or a combination of these, to assist with menstrual hygiene, and to provide contraception. Menstrual manipulation can be used to induce complete amenorrhea, regulate cycles, or decrease regular menstrual flow. However, treatment risks and side effects may have a different effect on the lives of these adolescents. The comfort level of health care providers to respond to the special concerns of adolescents with disabilities is low, and several barriers exist. This review addresses the complex issues of puberty, menstruation, sexuality, abuse, and safety highlighting the distinctive needs of this population. The options and decisions around menstrual manipulation are highlighted in detail. PMID:25004333

    A continued increase in the proportion of adolescents who never smoke, as well as an understanding of factors that influence reductions in smoking among this susceptible population, is crucial. The World Health Organization Framework Convention on Tobacco Control provides an appropriate structure to briefly examine Australian and New South Wales policies and programs that are influencing reductions in smoking among adolescents in Australia. This paper provides an overview of price and recent tax measures to reduce the demand for tobacco, the evolution of smoke-free environment policies, changes to tobacco labelling and packaging, public education campaigns, and restrictions to curb tobacco advertising. It also discusses supplyreduction measures that limit adolescents' access to tobacco products. Consideration is given to emerging priorities to achieve continued declines in smoking by Australian adolescents. PMID:26863168

Therefore, this study aimed to assess the excessive sleepiness frequency and the factors that might be associated to it in this population. Methods: The cross-sectional study analyzed 531 adolescents aged 10–18 years old from two private schools and one public school. Five questionnaires were applied: the Cleveland Adolescent Sleepiness Questionnaire; the Sleep Disturbance Scale for Children; the Brazilian Economic Classification Criteria; the General Health and Sexual Maturation Questionnaire; and the Physical Activity Questionnaire. The statistical analyses were based on comparisons between schools and sleepiness and non-sleepiness groups, using linear correlation and logistic regression. Results: Sleep deprivation was present in 39% of the adolescents; sleep deficit was higher in private school adolescents (p < 0.001, and there was a positive correlation between age and sleep deficit (p < 0.001; r = 0.337. Logistic regression showed that older age (p = 0.002; PR: 1.21 [CI: 1.07–1.36] and higher score level for sleep hyperhidrosis in the sleep disturbance scale (p = 0.02; PR: 1.16 [CI: 1.02–1.32] were risk factors for worse degree of sleepiness. Conclusions: Sleep deficit appears to be a reality among adolescents; the results suggest a higher prevalence in students from private schools. Sleep deprivation is associated with older age in adolescents and possible presence of sleep disorders, such as sleep hyperhidrosis.

    This study explores the association of family process and peer influences with risk behaviors of adolescents. A total of 805 students were recruited from secondary schools. The results showed that adolescents who have parents who are “authoritarian” (OR = 1.856) were more likely to smoke. Adolescents who have conflicts with their parents (OR = 1.423) were more likely to drink. Those who have parents who are “permissive” were less likely to drink (OR = 0.885).

    The purpose of this study was to examine physical activity levels and influencing individual and environmental factors in a group of adolescent survivors of cancer and a comparison group. Methods. The study was conducted using a "mixed methods" design. Quantitative data was collected from 48 adolescent survivors of cancer and 48 comparison adolescents using the Godin Leisure-Time Exercise Questionnaire, the Fatigue Scale-Adolescents, and the Amherst Health and Activity Study-Student Survey. Qualitative data was collected in individual semistructured interviews. Results. Reported leisure-time physical activity total scores were not significantly different between groups. Physical activity levels were positively correlated with adult social support factors in the group of adolescent survivors of cancer, but not in the comparison group. Time was the primary barrier to physical activity in both groups. Fatigue scores were higher for the comparison but were not associated with physical activity levels in either group. The qualitative data further supported these findings. Conclusions. Barriers to physical activity were common between adolescent survivors of cancer and a comparative group. Increased knowledge of the motivators and barriers to physical activity may help health care providers and families provide more effective health promotion strategies to adolescent survivors of pediatric cancer.

    There are dramatic individual differences among adolescents in how and when they become sexually active adults, and early sexual activity is frequently cited as a cause of concern for scientists, policymakers, and the general public. Understanding the causes and developmental impact of adolescent sexual activity can be furthered by considering genes as a source of individual differences. Quantitative behavioral genetics (i.e., twin and family studies) and candidate gene association studies now provide clear evidence for the genetic underpinnings of individual differences in adolescent sexual behavior and related phenotypes. Genetic influences on sexual behavior may operate through a variety of direct and indirect mechanisms, including pubertal development, testosterone levels, and dopaminergic systems. Genetic differences may be systematically associated with exposure to environments that are commonly treated as causes of sexual behavior (gene-environment correlation). Possible gene-environment correlations pose a serious challenge for interpreting the results of much behavioral research. Multivariate, genetically informed research on adolescent sexual behavior compares twins and family members as a form of quasi experiment: How do twins who differ in their sexual experiences differ in their later development? The small but growing body of genetically informed research has already challenged dominant assumptions regarding the etiology and sequelae of adolescent sexual behavior, with some studies indicating possible positive effects of teenage sexuality. Studies of Gene × Environment interaction may further elucidate the mechanisms by which genes and environments combine to shape the development of sexual behavior and its psychosocial consequences. Overall, the existence of heritable variation in adolescent sexual behavior has profound implications for environmentally oriented theory and research.

    Research on the quality of life (QL) of children/adolescents with psychological disorders has flourished over the last few decades. Given the developmental challenges of QL measurements in pediatric populations, the aim of this study was to ascertain the extent to which a developmental approach to QL assessment has been applied to pedopsychiatric QL research. A systematic literature search was conducted in three electronic databases (PubMed, PsycINFO, SocINDEX) from 1994 to May 2014. Quantitative studies were included if they assessed the self- or proxy-reported QL of children/adolescents with a psychological disorder. Data were extracted for study design, participants, QL instruments and informants, and statistical approach to age-related specificities. The systematic review revealed widespread utilization of developmentally appropriate QL instruments but less frequent use of both self and proxy reports and an inconsistent approach to age group specificities. Methodological guidelines are discussed to improve the developmental validity of QL research for children/adolescents with mental disorders.

    Studies have shown that it is necessary to create a database for dental maturity for every population and compare it to others. The present study is the first one for dental development in the Icelandic population the age range being 4-24 years. It will help in forensic dental age estimation and will also help dentists, physicians, anthropologists, archaeologists and other professionals who rely on developmental age assessment in children and adolescents. In this present retrospective cross-sectional study, dental maturity was determined in 1100 Icelandic children and adolescents from orthopantomograms (OPGs). The first 100 were used for a pilot study and the remaining 1000 for the main study. A total of 23 subjects were excluded. The sample consisted of 508 girls and 469 boys from the age of 4-24 years and a dental developmental scoring system was used as a standard for determination of dental maturity stages. A total of 200 OPGs were studied both on the left and right side and the remaining on the right side. Dental maturity was established for all teeth and both genders, when the sample permitted, from the beginning of crown formation to the root apex closure. The Cronbach's Alpha reliability test showed high reliability, R=0.982. Girls in Iceland reach dental maturity root completed (stage 10, Rc) at 17.81 years of age for the maxillary and at 18.47 years for the mandibular teeth. Boys reach dental maturity root completed (stage 10, Rc) at 18.00 years of age in the maxilla and 17.63 in the mandible. There was no significant difference between left and right side (r=0.95-1.00) and there was no gender difference, except in root formation in maxillary and mandibular canines where girls reached root completed earlier than boys. A reliable database has been established in Iceland for tooth development in the age range of 4-24 years, which is compatible with international studies. These results will help forensic odontologists and other professionals to estimate with

    The current study filled significant gaps in our knowledge of developmental psychopathology by examining the influence of multilevel risk factors and developmental assets on longitudinal trajectories of internalizing symptoms and self-esteem in an exceptionally culturally diverse sample of rural adolescents. Integrating ecological and social capital theories, we explored if positive microsystem transactions are associated with self-esteem while negative microsystem transactions increase the chances of internalizing problems. Data came from the Rural Adaptation Project, a 5-year longitudinal panel study of more than 4,000 middle school students from 28 public schools in two rural, disadvantaged counties in North Carolina. Three-level hierarchical linear modeling models were estimated to predict internalizing symptoms (e.g., depression, anxiety) and self-esteem. Relative to other students, risk for internalizing problems and low self-esteem was elevated for aggressive adolescents, students who were hassled or bullied at school, and those who were rejected by peers or in conflict with their parents. Internalizing problems were also more common among adolescents from socioeconomically disadvantaged families and neighborhoods, among those in schools with more suspensions, in students who reported being pressured by peers, and in youth who required more teacher support. It is likely that these experiences left adolescents disengaged from developing social capital from ecological microsystems (e.g., family, school, peers). On the positive side, support from parents and friends and optimism about the future were key assets associated with lower internalizing symptoms and higher self-esteem. Self-esteem was also positively related to religious orientation, school satisfaction, and future optimism. These variables show active engagement with ecological microsystems. The implications and limitations were discussed.

    We recently observed that social interactions influence morphine responsiveness in adolescent males. Given sex-related differences in both social interactions and responses to morphine, the present study examines social influences on morphine sensitization in adolescent female mice. Four experimental groups were examined: (1) morphine-treated mice (twice daily, 10-40 mg/kg, s.c.) housed physically and visually separated from saline-treated mice ('morphine only'), (2) morphine-treated mice housed together with saline-treated mice ('morphine cage-mates (of saline)'), (3) saline-treated mice housed together with morphine-treated mice ('saline cage-mates (of morphine)'), and (4) saline-treated mice housed physically and visually separated from morphine-treated mice ('saline only'). Following the treatment period, mice were tested individually for their locomotor response to 20 mg/kg morphine (s.c.). There were no significant differences in morphine-induced hyper-locomotion between saline only and saline cage-mates (of morphine) female adolescent mice. Notably, morphine only mice exhibited significantly greater morphine sensitization as compared to morphine cage-mates (of saline). Thus, this study demonstrates social influences on morphine sensitization in adolescent females. Drug use during early adolescence is a key predictor of later drug abuse and dependence during adulthood. Thus, understanding the specific vulnerabilities to drug use in this age group may represent a first step in helping develop more effective treatment programs. PMID:20456874

    Schizophrenia (SCH) and pervasive developmental disorders (PDDs) belong to different diagnostic categories. There is, however, overlap between these 2 diagnostic groups. The aim of this preliminary study was to evaluate some aspects of neurocognitions and social cognitions in adolescents with SCH (n = 10, 2 boys and 8 girls; age range = 13.3-17.7 years), a PDD (n = 15, 7 boys and 8 girls; age range = 13.3-18.0 years), or both disorders (n = 8, 5 boys and 3 girls; age range = 13.5-18 years). Eight subtests (Information, Similarities, Arithmetic, Comprehension, Picture Completion, Coding B, Block Design, and Object Assembly) of the Wechsler Intelligence Scale for Children-Third Version and 2 subtests (Theory of Mind [ToM] and Affect Recognition) of the NEPSY-II were administered. Adolescents with both disorders and those with a PDD only performed better on visual processing tasks than did adolescents with SCH only. On the other hand, adolescents with both disorders as well as those with SCH only experienced more problems with processing speed than did adolescents with a PDD only. Adolescents with SCH only performed significantly more poorly with verbal ToM tasks compared with those with a PDD only. Adolescents with both disorders performed as well as those with SCH only. All in all, our preliminary findings support the current idea that SCH and PDDs are separate disorders. PMID:27015370

    Full Text Available Abstract Background Physical inactivity is increasing among adolescents in the U.S., especially among girls. Despite growing evidence that parents are an important influence on adolescent health, few longitudinal studies have explored the causal relationship between parental influence and physical activity. This study examines how the relationships between parental influences and adolescent physical activity differ by gender and tests whether these relationships are mediated by adolescents' self-esteem and depression. Methods Data are from the National Longitudinal Study of Adolescent Health. The sample includes 13,246 youth, grades 7 to 12, interviewed in 1995 and again 1 year later. Logit models were used to evaluate parental influences on achieving five or more bouts of moderate to vigorous physical activity per week [MVPA] and whether the relationship between parental influence and MVPA was mediated by adolescents' level of self-esteem and depression. Results Family cohesion, parent-child communication and parental engagement positively predicted MVPA for both genders one year later (odds ratios and 95% confidence intervals for females, 1.09 [1.05–1.12], 1.13 [1.07–1.19], 1.25 [1.17–1.33] and males, 1.08 [1.04–1.11], 1.14 [1.07–1.23], 1.23 [1.14–1.33], respectively; however, parental monitoring did not (odds ratio and confidence intervals for females and males, 1.02 [.97–1.07]. For both females and males, self-esteem mediated the relationship between parental influence and physical activity. Depressive symptoms were only a mediator among males. Females reported higher levels of parent-child communication and lower family cohesion compared with males. There were no gender differences in levels of parental monitoring and engagement. Females had significantly lower levels of self-esteem and higher levels of depressive symptoms than males. Conclusion Strategies to promote physical activity among adolescents should focus on

    The purpose of this article is to present findings from two parallel qualitative studies that used focus groups to explore adolescent views of psychological wellness and healthy bodies. Nine focus groups were held with 46 adolescents aged 16-19 years from two Mid-Western Canadian high schools. Both studies were designed with an interpretive humanist perspective and then a 6-step thematic approach was used to analyze the data. Common themes emerging in the focus group discussions in both studies included the negative impact of media on adolescent body image and pressure to conform to the Western views of physical appearance. These findings illustrate the need for nurses to understand the influence of the media on adolescents' views of their body image and to incorporate protocols for assessment, education, and counseling of adolescents on the healthy usage of media into their pediatric clinical practice. Through consistent participation in the development and implementation of health policies, nurses play a critical role in supporting adolescents to develop healthy views of body image.

    2015-11-01

    The current study examined the prospective association between child maltreatment and the development of substance use disorder in adolescence with the aim of investigating pathways underlying this relation, as well as genetic moderation of these developmental mechanisms. Specifically, we tested whether youth who experienced maltreatment prior to age 8 were at risk for the development of marijuana dependence in adolescence by way of a childhood externalizing pathway and a childhood internalizing pathway. Moreover, we tested whether variation in FK506 binding protein 5 gene (FKBP5) CATT haplotype moderated these pathways. The participants were 326 children (n =179 maltreated; n = 147 nonmaltreated) assessed across two waves of data collection (childhood: ages 7-9 and adolescence: ages 15-18). Results indicated that higher levels of child externalizing symptoms significantly mediated the effect of child maltreatment on adolescent marijuana dependence symptoms for individuals with one or two copies of the FKBP5 CATT haplotype only. We did not find support for an internalizing pathway from child maltreatment to adolescent marijuana dependence, nor did we find evidence of moderation of the internalizing pathway by FKBP5 haplotype variation. Findings extend previous research by demonstrating that whether a maltreated child will traverse an externalizing pathway toward substance use disorder in adolescence is dependent on FKBP5 genetic variation.

    Is the marriage behavior of young people determined by their socioeconomic characteristics or their endorsement of developmental idealism? This article addresses this question using a unique longitudinal data set from Nepal and provides the first individual-level test of developmental idealism theory. The authors find that unmarried individuals with greater endorsement of developmental idealism in 2008 were more likely by 2012 to choose their own spouse, including a spouse of a different caste, rather than have an arranged marriage. Those with salaried work experience were also less likely to have arranged marriages, but urban proximity and education were not significant. The authors conclude that both developmental idealism and socioeconomic characteristics influence marriage and that their influences are largely independent. PMID:26430712

    This cultural-developmental interview study examined moral reasoning in relation to religious culture (evangelical, mainline Protestants), age (children, adolescents, adults), and moral issue (public, private; N = 120). Compared to adolescents and adults, children used more Ethic of Autonomy and less Ethic of Community reasoning. With age, differences between religious cultures became pronounced. Mainline adults invoked an Ethic of Divinity for private issues. Evangelical adolescents and adults used this ethic frequently, but more for public than private issues. These and other findings indicate that evangelical and mainline Protestants diverge on what should be society's moral lingua franca, and cast new and nuanced light on America's "culture wars." Results furthermore highlight comodulation of development and culture that requires life course research on moral reasoning.

    There have been rapid advances in understanding a broad range of changes in brain structure and function during adolescence, and a growing interest in identifying which of these neurodevelopmental changes are directly linked with pubertal maturation—at least in part because of their potential to provide insights into the numerous emotional and behavioral health problems that emerge during this developmental period. This review focuses on what is known about the influence of puberty on white matter development in adolescence.We focus on white matter because of its role in providing the structural architectural organization of the brain and as a structural correlate of communication within complex neural systems. We begin with a review of studies that report sex differences or sex by age interactions in white matter development as these findings can provide, although indirectly,information relevant to puberty-related changes. Studies are also critically reviewed based on methodological procedures used to assess pubertal maturation and relations with white matter changes. Findings are discussed in light of their implications for the development of neural systems underlying the regulation of emotion and behavior and how alterations in the development of these systems may mediate risk for affective disorders in vulnerable adolescents.

    Recent research has suggested that the presence of significant levels of callous-unemotional (CU) traits designates a clinically important and etiologically distinct subgroup of children and adolescents with serious conduct problems. Based on this research, CU traits have been included in the most recent revision of the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5; American Psychiatric Association, 2013)--as a specifier for the diagnosis of conduct disorder. In this review, we attempt to understand CU traits within a developmental psychopathological framework. Specifically, we summarize research on the normal development of the prosocial emotions of empathy and guilt (i.e., conscience) and we illustrate how the development of CU traits can be viewed as the normal development of conscience gone awry. Furthermore, we review research on the stability of CU traits across different developmental periods and highlight factors that can influence this stability. Finally, we highlight the implications of this developmental psychopathological framework for future etiological research, for assessment and diagnostic classification, and for treatment of children with serious conduct problems.

    Full Text Available Abstract Background Little is known about the Quality of Life (QOL in parents of children with developmental diseases as compared to other severe neurological or psychiatric disorders. Aims of the present study were: to evaluate QOL in parents of children affected by Pervasive Development Disorder (PDDs, Cerebral Palsy (CP or Mental Retardation (MR as compared to a control group (CG; to evaluate QOL of parents of patients with different types of PDDs, namely Autistic Disorder (AD, High Function Autism/Asperger Syndromes (HFA/AS and Pervasive Developmental Disorder Not Otherwise Specified (PPD-NOS; and to compare the level of impairment in QOL of mothers and fathers within PDDs, CP, MR groups and between AD, HFA/AS, PDD-NOS sub-groups. Methods The sample consisted of 212 parents (115 mothers and 97 fathers of 135 children or adolescents affected by PDDs, MR or CP. An additional sample of 77 parents (42 mothers and 35 fathers of 48 healthy children was also included and used as a control group. QOL was assessed by the WHOQOL-BREF questionnaire. Results Compared with parents of healthy children, parents in the PDDs group reported impairment in physical activity (p = 0.0001 and social relationships (p = 0.0001 and worse overall perception of their QOL (p = 0.0001 and health (p = 0.005. Scores in the physical (p = 0.0001, psychological (p = 0.0001 and social relationships domains (p = 0.0001 and in the physical (p = 0.0001 and social relationships (p = 0.0001 domains were lower compared to the MR group CP group respectively. Little differences were observed between MR, CP and control groups. The level of impairment of physical (p = 0.001 and psychological (p = 0.03 well-being were higher in mothers than in fathers in the PDDs and CP groups respectively; in the other groups, and across all the other domains of QQL impairment was similar. There were no statistically significant differences in the scores between the AD, HFA/AS and PDD-NOS sub

    Background This retrospective study aimed to investigate the difference of the intra-dural reserving space for spinal cord in magnetic resonance imaging (MRI) between patients with and without developmental cervical stenosis and its clinical significance.Methods A total of 264 patients with cervical spondylotic myelopathy who had decompression surgeries were recruited.The average follow-up was 29 months.Based on their lateral radiographs,they were divided into stenosis group and non-stenosis group.On the magnetic resonance images,the ratio of the sagittal diameter of the dural sac to that of the vertebral body was measured and calculated as MRI Pavlov ratio at the mid-vertebral level on T2-weighted sagittal images from C3 to C7.The ratio of the transverse area of the spinal cord to that of the dural sac was measured and calculated as occupation ratio on T2-weighted axial images at the same levels.The MRI Pavlov ratio and occupation ratio were compared between the two groups.The stenosis group was further divided into space-reserving and non-space-reserving subgroups based on the occupation ratios; then clinical parameters were compared between the two subgroups to determine the clinical significance of the reserving space.Results The MRI Pavlov ratio of the stenosis group was significantly smaller than that of the non-stenosis group at C3-C7 (P <0.01),while the occupation ratio was significantly larger only at C7 (P <0.05).For the space-reserving subgroup,the postoperative recovery rate was lower (P <0.05).The postoperative recovery rate was (23±6)% in anterior approach,larger than (-23±15)% in posterior approach (P <0.05).Conclusions Developmental cervical stenosis is associated with a smaller sagittal diameter of the dural sac,but does not lead to a significant decrease in intra-dural space available for the cord.For patients with normal intra-dural space,the recovery after anterior decompression surgery was better than posterior approach.

    2015-06-01

    This three-wave cohort-sequential longitudinal study (N = 1302) examined the development of two core political attitudes, economic egalitarianism and ethnocentrism, among Dutch youths between age 12 and 31. Longitudinal regression analyses revealed a curvilinear mean level development for both attitudes, reflecting an increased disagreement with economic redistribution and multiculturalism around late adolescence. Furthermore, attitudes became decreasingly polarized (i.e., less extreme) and increasingly stable with age. Finally, several effects of attitudes' correlates gradually changed: The effect of educational level on ethnocentrism increased with age, whereas the effect of gender diminished. Regional effects on ethnocentrism developed as youths resided in a new area. No age-related change was found in the effect of parental SES. Overall, these findings support the idea that attitudes mature during the formative phase of adolescence and that this process slows down during emerging adulthood. Furthermore, these results support developmental explanations for the association between attitudes and their correlates. PMID:25880889

    Intergroup contact represents a powerful way to improve intergroup attitudes and to overcome prejudice and discrimination. However, long-term effects of intergroup contact that consider social network dynamics have rarely been studied at a young age. Study 1 validated an optimized social network approach to investigate intergroup contact (N = 6,457; Mage  = 14.91 years). Study 2 explored the developmental trajectories of intergroup contact by applying this validated network approach in a cross-sequential design (four-cohort-four-wave; N = 3,815; 13-26 years). Accelerated growth curve models showed that contact predicts the development of attitudes in adolescence, whereas acquired attitudes buffer against decreasing contact in adulthood. Findings highlight the potential of social network analysis and the developmental importance of early intergroup contact experiences. PMID:27684399

    2015-12-01

    The purpose of this study was to examine the sociocultural factors related to weight behaviors in African American adolescents utilizing a social ecological approach. A descriptive correlational design included a sample of 145 African American adolescents. Perceived familial socialization, ethnic identity, physical activity, and eating behavior patterns were measured. Data were analyzed using descriptive statistics, Pearson product-moment correlations, and multiple regression equations. Perceived maternal socialization was significantly related to adolescent eating behaviors and physical activity whereas perceived paternal socialization was significantly related only to their physical activity. The adolescents' ethnic identity was not significantly related to their eating behaviors or physical activity. Health care providers who work with adolescents and their families can use the initial findings from this study to encourage healthy weight-related behaviors while reducing the obesity epidemic within the African American adolescent population in a developmentally appropriate and culturally sensitive manner.

    Parental and peer influences on adolescent substance use have been well demonstrated. However, limited research has examined how parental and peer influences vary across school contexts. This study used a multilevel approach to examine the effects of school substance use norms and school racial composition in predicting adolescent substance use (a composite measure of alcohol, tobacco, and marijuana use) and in moderating parental and peer influences on adolescent substance use. A total of 14,346 adolescents from 34 schools in a mid-western county completed surveys electronically at school. Analyses were conducted using hierarchical linear modeling. Results indicated that school-level disapproval against substance use and percentage of minority students at school were negatively associated with adolescent substance use. School-level disapproval moderated the association between peer substance use and adolescent substance use, with the association being stronger when school-level disapproval was lower. School racial composition moderated the influence of parental disapproval and peer substance use on adolescent substance use. Specifically, both the association between parental disapproval and adolescent substance use and the association between peer substance use and adolescent substance use were weaker for adolescents who attended schools with higher percentages of minority students. Findings highlighted the importance of considering the role of school contexts, in conjunction with parental and peer influences, in understanding adolescent substance use. PMID:27215854

    Full Text Available Puberty is a very important process for adolescents. Physiological changes and body modifications lead to great vulnerability. This vulnerability is connected to the adolescent’s perceptions of the uncertainty of outcomes due to the transformation of their infant body into an adult one. This cross-sectional study aims to better understand whether body image perception and satisfaction influence self-esteem in a sample of Italian male and female adolescents. A total of 242 adolescents (120 male and 122 female individuals aged 11 to 17 years (M = 13.33; SD = 1.7 completed the study measures. Quantitative and qualitative instruments were used. In particular, adolescents completed self-report questionnaires to assess their pubertal status (Pubertal Developmental Scale, Peterson, Crockett, Richards, & Boxer, 1988, their body esteem (Body Esteem Scale, Mendelson, Mendelson, & White, 2001, their body image (Body Image Satisfaction Questionnaire, Rauste-von Wright, 1989, and their self-esteem (Rosenberg Self-Esteem Scale, Rosenberg,1965. Adolescent were also invited to depict themselves to assess their body representations by completing the Drawing Me test (Confalonieri, 2011. Results from MANOVAs confirm that gender and age are two factors that influence body image perception and satisfaction. SEM analyses show that good self-esteem is reached through good body satisfaction following different trajectories in male and female individuals. Data from adolescents’ body representations obtained via drawings confirm that females are more concerned about their body changes and about the appearance of secondary sexual features than males. This research, stressing the influence of various individual factors and highlighting the psychological distress and dissatisfaction of adolescents, especially females, confirms the importance of studying this topic in order to generate preventive measures to help adolescents through this developmental task.

    Behavioral inhibition (BI) is a temperament characterized by social reticence and withdrawal from unfamiliar or novel contexts and conveys risk for social anxiety disorder. Developmental outcomes associated with this temperament can be influenced by children's caregiving context. The convergence of a child's temperamental disposition and rearing environment is ultimately expressed at both the behavioral and neural levels in emotional and cognitive response patterns to social challenges. The present study used functional neuroimaging to assess the moderating effects of different parenting styles on neural response to peer rejection in two groups of adolescents characterized by their early childhood temperament (M(age) = 17.89 years, N = 39, 17 males, 22 females; 18 with BI; 21 without BI). The moderating effects of authoritarian and authoritative parenting styles were examined in three brain regions linked with social anxiety: ventrolateral prefrontal cortex (vlPFC), striatum, and amygdala. In youth characterized with BI in childhood, but not in those without BI, diminished responses to peer rejection in vlPFC were associated with higher levels of authoritarian parenting. In contrast, all youth showed decreased caudate response to peer rejection at higher levels of authoritative parenting. These findings indicate that BI in early life relates to greater neurobiological sensitivity to variance in parenting styles, particularly harsh parenting, in late adolescence. These results are discussed in relation to biopsychosocial models of development. PMID:25588884

    Fuchs, M

    2008-02-01

    The incidence of dysphonia among children and adolescents is evaluated internationally at 6 % to 25 %. Nonetheless, hoarseness as a leading symptom among children is often insufficiently recognized by their parents/attachment figures, by the young patients themselves, and even by physicians. In an overview, the hereditary and acquired organic and functional causes - including secondary organic lesions of the vocal folds - their pathomechanisms and the symptoms typical for this age group are presented. For diagnostics suitable for these age groups and developmental stages, modern methods of laryngoscopy (including stoboscopy and real-time laryngoscopy), of functional diagnostics of vocal capacity and quality as well as anamnestic and psychometric procedures for the investigation of possible psychosomatic genesis are available. Frequent therapeutic measures are vocal hygienic counseling and psycho- and family dynamic therapies. Vocal exercise treatments are particularly employed for the consequences of laryngeal surgery and with voice techniques unfavorable as a precondition for increased vocal activity. Operative measures in the sound-producing areas of the vocal apparatus and in the framework of plastic reconstruction concentrate on the optimizing of vocal capacity and quality. In clinical routine, symptoms of dysphonia in children and adolescents should be consciously registered, and any long-term hoarseness, in this age group as well, should be examined by specialized physicians using the methods suitable to the age group and the developmental stage. When the appropriate indications are present, all of the therapeutic options currently available should be discussed.

  6. Inhibiting influence of testosterone on stress responsiveness during adolescence.

    2011-11-01

    The maturation of the hypothalamo-pituitary-adrenal (HPA) axis is a key-component of the changes that occur during adolescence. In guinea pigs, HPA responsiveness during late adolescence depends strongly on the quantity and quality of social interactions: Males that lived in a large mixed-sex colony over the course of adolescence exhibit a lower stress response than males that were kept in pairs (one male/one female). Since colony-housed males have higher testosterone (T) levels than pair-housed males, and inhibiting effects of T on HPA function are well known, we tested the hypothesis that the decrease in stress responsiveness found in colony-housed males is due to their high T concentrations. We manipulated T levels in two experiments: 1) gonadectomy/sham-gonadectomy of colony-housed males (which usually have high T levels), 2) application of T undecanoate/vehicle to pair-housed males (which usually have low T levels). As expected, gonadectomized males showed a significantly increased stress response in comparison with sham-gonadectomized males, and T-injected males had a significantly lower stress response than vehicle-injected males. Both experiments thus confirm an inhibiting effect of T on HPA responsiveness during adolescence, which can mediate the influence of social interactions. The reduction in stress responsiveness is hypothesized to have a biologically adaptive value: A sudden increase in glucocorticoid concentrations can enhance aggressive behavior. Thus, pair-housed males might be adapted to aggressively defend their female ('resource defense strategy'), whereas colony-housed males display little aggressive behavior and are capable of integrating themselves into a colony ('queuing strategy').

    2011-07-01

    Full Text Available We investigate if concentrative meditation training (CMT offered during adolescent development benefits subsystems of attention using a quasi-experimental design. Attentional alerting, orienting, and conflict monitoring were examined using the Attention Network Test (ANT in 13, 14, and 15 yo children who received CMT as part of their school curriculum (CMT Group: N=79 vs. those who received no such training (Control Group: N=76. Alerting and conflict monitoring, but not orienting, differed between the CMT and Control Group. Only conflict monitoring demonstrated age-related improvements, with smaller conflict effect scores in older vs. younger participants. The influence of CMT on this system was similar to the influence of developmental maturity, with smaller conflict effects in the CMT vs. Control group. To examine if CMT might also bolster conflict-triggered upregulation of attentional control, conflict effects were evaluated as a function of previous trial conflict demands (high conflict vs. low conflict. Smaller current trial conflict effects were observed when previous conflict was high vs. low, suggesting that similar to adults, when previous conflict was high (vs. low children in this age-range proactively upregulated control so that subsequent trial performance was benefitted. The magnitude of conflict-triggered control upregulation was not bolstered by CMT but CMT did have an effect for current incongruent trials preceded by congruent trials. Thus, CMT’s influence on attention may be tractable and specific; it may bolster attentional alerting, conflict monitoring and reactive control, but does not appear to improve orienting.

    Family cohesion relates to positive outcomes for both parents and children. Maintaining cohesion may be especially challenging for families of adolescents with developmental disabilities, yet this has been studied infrequently in this group. We investigated cohesion in these families, particularly with respect to partner stress, using the notion of the 'spillover effect' as a model. Adolescents with disabilities and their parents participated. Parents reported on teen adaptive and problem behaviours and on marital satisfaction, parenting stress, and family cohesion. The stress of one partner was tested as a predictor of the quality of family cohesion reported by the other. Adolescent behaviour problems were negative predictors of family cohesion in mothers, and marital satisfaction positively predicted cohesion for both parents. Above other factors, greater partner stress predicted poorer family cohesion for both fathers and mothers. Marital satisfaction acted as a suppressor of this relation. To improve the overall climate of families, care providers should take into consideration individual relationships, including the marital relationship. In addition, the possibility of spillover from one individual to another should be recognized as a factor in family functioning. Family-centred practices are likely to lead to greater feelings of cohesion and overall better individual and family well-being. PMID:26741262

    Childhood aggression-disruptiveness (AD), chronic peer rejection, and deviant friendships were examined as predictors of early-adolescent rule-breaking behaviors. Using a sample of 383 children (193 girls and 190 boys) who were followed from ages 6 to 14, peer rejection trajectories were identified and incorporated into a series of alternative models to assess how chronic peer rejection and deviant friendships mediate the association between stable childhood AD and early-adolescent rule breaking. There were multiple mediated pathways to rule breaking that included both behavioral and relational risk factors, and findings were consistent for boys and girls. Results have implications for better understanding the influence of multiple social processes in the continuity of antisocial behaviors from middle childhood to early adolescence. PMID:25403544

    This study investigated gender role influences on Turkish adolescents' self-identity process as part of the International Self-Identity Research Project. A total of 154 male and 119 female adolescents ages 14 through 17 from urban and rural areas of Turkey were surveyed through a questionnaire. The results indicated that "family" was the dominant source of belongingness for both males and females, followed by "friendships" and "school." Friendships and education were valued more by females than by males. Symbolic items (e.g., relationships, happiness) influenced females' self-identity more than they did males, while males tended to place greater importance on material items (e.g., home, TV, sports equipment). Athletic activities were highly important in males' self-validation process while females were oriented more toward the artistic and creative. General affective attributes (e.g., honesty, respect, thoughtfulness) were similarly valued by males and females as important criteria for self-evaluation. Finally, males were more religious, patriotic, and felt stronger ties to ancestors while females appeared to be more altruistic and placed high importance on social relations. PMID:9105502

    2016-01-01

    In this study, we examined factors that influenced doula use among adolescent mothers in a community-based childbirth education and doula program. We used a qualitative case study approach to gather perspectives from adolescent mothers and doulas through semistructured interviews, field observations, and a focus group. These women collectively revealed multiple themes related to doula use among adolescent mothers, including relationship development and barriers to doula use at the individual and structural levels. Effective training and support for doulas that serve adolescent clients can improve these mothers' birth experiences, and program planners in the United States and other countries can use process evaluations to improve doula programs for adolescent mothers.

    Using data from a 6-year longitudinal follow-up sample of 240 youth who participated in a randomized experimental trial of a preventive intervention for divorced families with children ages 9-12, the current study tested alternative cascading pathways by which the intervention decreased symptoms of internalizing disorders, symptoms of externalizing disorders, substance use, and risky sexual behavior and increased self-esteem and academic performance in mid- to late adolescence (15-19 years old). It was hypothesized that the impact of the program on adolescent adaptation outcomes would be explained by progressive associations between program-induced changes in parenting and youth adaptation outcomes. The results supported a cascading model of program effects in which the program was related to increased mother-child relationship quality that was related to subsequent decreases in child internalizing problems, which then was related to subsequent increases in self-esteem and decreases in symptoms of internalizing disorders in adolescence. The results were also consistent with a model in which the program increased maternal effective discipline that was related to decreased child externalizing problems, which was related to subsequent decreases in symptoms of externalizing disorders, less substance use, and better academic performance in adolescence. There were no significant differences in the model based on level of baseline risk or adolescent gender. These results provide support for a cascading pathways model of child and adolescent development.

  9. Family influences on adolescent gambling behavior: a review of the literature.

    McComb, Jennifer L; Sabiston, Catherine M

    2010-12-01

    Gambling, and gambling related problems, are recognized as an emerging health issue among adolescents. Adolescent gambling is associated with numerous individual, social, and family characteristics. This paper provides a review of 21 empirical studies published between 1997 and 2008 that examine family influences on adolescent gambling behavior. Family influences on gambling behavior are conceptualized in the following five domains: (1) family sociodemographic factors, (2) general family climate, (3) family members' attitudes and behaviors, (4) parenting practices, and (5) family relationship characteristics. Based on the review of extant literature, there is empirical evidence that family characteristics are associated with adolescent gambling and further examination of family system influences on gambling behavior is needed. Gaps in the current literature and recommendations for future research are discussed to help inform the study of family influences on adolescent gambling behavior.

    2012-02-01

    OBJECTIVE: EPICA is the first large-scale Irish study of a school-going population examining the impact of media influences on eating attitudes. METHOD: Students were screened using the EAT-26, EDI-III and a study-specific questionnaire. A sub-sample of parents\\' views was included. RESULTS: Three thousand and thirty-one students (mean age 14.74) and 56 parents enrolled. The majority (71.4%) of adolescents felt adversely affected by media portrayal of body weight and shape, with more than a quarter (25.6%) believing it to be \\'far too thin\\'. A significant correlation between media impact and high EAT scores (chi2 = 450.78, df = 2, p < 0.05) and EDI-III scores (chi2 = 387.51, df = 4, p < 0.05) was demonstrated. Parents also view media portrayal as too thin (94.7%), less than half are adversely affected by it (49.2%) but the majority (71.9%) believe their children to be. CONCLUSION: Media portrayal of body weight and shape is correlated with eating psychopathology and may affect adolescents more than adults. School psycho-educational programmes and media policies are urgently needed to minimise any detrimental effect.

    Full Text Available The aim of this study was to investigate the degree to which genetic and environmental influences affect variation in adolescent exercise behavior. Data on regular leisure time exercise activities were analyzed in 8,355 adolescent twins, from three-age cohorts (13-14, 15-16, and 17–19 years. Exercise behavior was assessed with survey items about type of regular leisure time exercise, frequency, and duration of the activities. Participants were classified as sedentary, regular exercisers, or vigorous exercisers. The prevalence of moderate exercise behavior declined from age 13 to 19 years with a parallel increase in prevalence of sedentary behavior, whereas the prevalence of vigorous exercise behavior remained constant across age cohorts. Variation in exercise behavior was analyzed with genetic structural equation modeling employing a liability threshold model. Variation was largely accounted for by genetic factors (72% to 85% of the variance was explained by genetic factors, whereas shared environmental factors only accounted for a substantial part of the variation in girls aged 13-14 years (46%. We hypothesize that genetic effects on exercise ability may explain the high heritability of exercise behavior in this phase of life.

    2011-01-01

    Full Text Available Positive relationships within the family, parental support, a consistent and constructive parental discipline style and adult supervision tend to be related negatively to adolescents deviant behaviors and their associations with deviant peers. Poor family relationships were found to be associated with higher levels of delinquent behaviors, possibly due to the fact that parents in those families provided poor role models and engaged in ineffective discipline strategies. Problem statement: A considerable number of secondary school students were involved in delinquent behavior and they are not doing well in school. School authorities with the supervision of education departments and the Ministry of Education have done their best to guide and monitor students’ discipline. Yet the problems related to misbehavior still occur in schools. A study was conducted on 113 at risk students to examine whether parental factors could contribute to their misbehavior problems. Approach: Interviews were conducted using open ended questions. Data were analyzed qualitatively using in vivo software to extract categories of parental influence. Results and Conclusion: Findings showed that the adolescents do have problems with their families including lack of parental attention, communication problems and poor relationship between parents. The implications of the findings were discussed.

    Psychological scientists have long sought to determine the relative impact of environmental influences over development and behavior in comparison with the impact of personal, dispositional, or genetic influences. This has included significant interest in the role played by media in children's development with a good deal of emphasis on how violent media spark and shape aggressive behavior in children and adolescents. Despite a variety of methodological weaknesses in his meta-analysis, Ferguson (2015, this issue) presents evidence to support the positive association between violent media consumption and a number of poor developmental outcomes. In this Commentary we discuss this meta-analytic work and how it fits into a broader understanding of human development. PMID:26386004

    Research on resilience and vulnerability can offer very valuable information for optimizing design and assessment of interventions and policies aimed at fostering adolescent health. This paper used the adversity level associated with family functioning and the positive adaptation level, as measured by means of a global health score, to distinguish four groups within a representative sample of Spanish adolescents aged 13–16 years: maladaptive, resilient, competent and vulnerable. The aforementioned groups were compared in a number of demographic, school context, peer context, lifestyles, psychological and socioeconomic variables, which can facilitate or inhibit positive adaptation in each context. In addition, the degree to which each factor tended to associate with resilience and vulnerability was examined. The majority of the factors operated by increasing the likelihood of good adaptation in resilient adolescents and diminishing it in vulnerable ones. Overall, more similarities than differences were found in the factors contributing to explaining resilience or vulnerability. However, results also revealed some differential aspects: psychological variables showed a larger explicative capacity in vulnerable adolescents, whereas factors related to school and peer contexts, especially the second, showed a stronger association with resilience. In addition, perceived family wealth, satisfaction with friendships and breakfast frequency only made a significant contribution to the explanation of resilience. The current study provides a highly useful characterization of resilience and vulnerability phenomena in adolescence. PMID:27458397

  16. Gaining insight into adolescent vulnerability for social anxiety from developmental cognitive neuroscience

    Directory of Open Access Journals (Sweden)

    Justin D. Caouette

    2014-04-01

    Full Text Available Social anxiety disorder (SAD markedly impairs daily functioning. For adolescents, SAD can constrain typical development precisely when social experiences broaden, peers’ opinions are highly salient, and social approval is actively sought. Individuals with extreme, impairing social anxiety fear evaluation from others, avoid social interactions, and interpret ambiguous social cues as threatening. Yet some degree of social anxiety can be normative and non-impairing. Furthermore, a temperament of behavioral inhibition increases risk for SAD for some, but not all adolescents with this temperament. One fruitful approach taken to understand the mechanisms of social anxiety has been to use neuroimaging to link affect and cognition with neural networks implicated in the neurodevelopmental social reorientation of adolescence. Although initial neuroimaging studies of adolescent SAD and risk for SAD underscored the role of fear-processing circuits (e.g., the amygdala and ventral prefrontal cortex, recent work has expanded these circuits to include reward-processing structures in the basal ganglia. A growing focus on reward-related neural circuitry holds promise for innovative translational research needed to differentiate impairing from normative social anxiety and for novel ways to treat adolescent SAD that focus on both social avoidance and social approach.

    2016-08-01

    For an adolescent with physical disabilities, intellectual disabilities, or both, and for her caregivers, menstruation can present significant challenges. If, after an evaluation, the adolescent, her family, and the obstetrician-gynecologist have decided that menstrual intervention is warranted, advantages and disadvantages of hormonal methods should be reviewed and individualized to each patient's specific needs. Complete amenorrhea may be difficult to achieve, and realistic expectations should be addressed with the patient and her caregivers. The goal in menstrual manipulation should be optimal suppression, which means a reduction in the amount and total days of menstrual flow. Menstrual suppression before menarche and endometrial ablation are not recommended as treatments. Optimal gynecologic health care for adolescents with disabilities is comprehensive; maintains confidentiality; is an act of dignity and respect toward the patient; maximizes the patient's autonomy; avoids harm; and assesses and addresses the patient's knowledge of puberty, menstruation, sexuality, safety, and consent.

The current study conducted a meta-analysis of twin studies on sex differences in self- and parent-reported adolescent depressive symptoms. For self-reports, genetic factors influenced adolescent depressive symptoms equally for boys and girls, accounting for 46% of variation, but shared environmental factors had stronger impacts on adolescent girls’ versus boys’ depressive symptoms (13% versus 1% of the variance. For parent-reports, genetic, shared, and nonshared environmental factors influenced adolescent depressive symptoms equally, with separate estimates of 34%, 35%, and 31%. The implications of sex difference in genetic and environmental etiologies of depressive symptoms are discussed.

    Zimmer-Gembeck, Melanie J; Siebenbruner, Jessica; Collins, W Andrew

    2004-08-01

    Theories and empirical studies of adolescent sexual behavior have identified the contributions of personal attributes and social experiences; however, it is rare that models have clarified developmental pathways to adolescent sexual behavior that include (1) factors assessed prior to and early in adolescence and (2) dyadic experiences in adolescence that provide the opportunity for sexual behavior (i.e., dating). Using data from a prospective study, structural equation modeling was used to test a model predicting adolescent sexual behavior at age 19, denoted by the number of lifetime sexual partners. Predictors examined were sociability and impulsivity assessed at 30 months of age, physical characteristics and experiences with peers measured at age 12-13, the age of first romantic relationship, and frequency of alcohol use at age 16. The pathway to greater sexual involvement was marked by some desired personal attributes (e.g., sociability) and peer experiences (e.g., higher quality friendships). These associations were mediated, however, by earlier initiation of romantic relationships and more frequent use of alcohol in middle adolescence. Earlier initiation of romantic relationships and more frequent alcohol use were predicted by greater sociability and less impulsivity in childhood, higher quality friendships and greater peer acceptance in early adolescence, and a more mature appearance and physical attractiveness (among females) at age 13. The findings imply a complex pathway that leads to a greater accumulation of sexual partners by age 19. This pathway begins in childhood and includes individual qualities, peer acceptance, romantic relationships, and alcohol use. PMID:15162084

    Science.gov (United States)

    Fuligni, Andrew J; Tsai, Kim M

    2015-01-01

    The socioeconomic and cultural changes that result from an increasingly interconnected world have been speculated to have important implications for the nature of adolescent development. Unfortunately, the historical time necessary for these changes to take place means that definitive research on the impact of globalization necessarily will be slow in forthcoming. Adolescents from immigrant families, however, already experience the social and cultural shifts thought to typify globalization, and an analysis of their experiences could shed light on what to expect as existing national barriers become more permeable. The value of flexibility in the face of great social and cultural change appears to be the dominant theme from research on immigrant youth, although that flexibility can be constrained by socioeconomic, ethnic, and racial stratification systems in host societies. This review highlights the implications of these findings for what may lie ahead for teenagers as globalization continues to expand.

    2016-04-01

    While adults are assumed to have the capacity to consent to medical research, and young children to have no capacity, adolescents' capacity to consent is not well described. Adapting the MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR), we describe adolescents' capacity to consent to medical research and factors influencing that capacity. Our pilot study included a community-based sample of 30 adolescents, 14 to 21 years of age, who completed the MacCAT-CR after undergoing a simulated informed consent process. We found that adolescents' capacity to consent to research was associated with age, health literacy, and family affluence. These findings suggest that investigators and institutional review boards should be aware that factors other than age may influence capacity to consent, and, for modifiable factors, such as health literacy, consent processes for medical research with adolescents can be modified.

  16. GFAPδ expression in glia of the developmental and adolescent mouse brain.

    Directory of Open Access Journals (Sweden)

    Carlyn Mamber

    Full Text Available Glial fibrillary acidic protein (GFAP is the major intermediate filament (IF protein in astrocytes. In the human brain, GFAP isoforms have unique expression patterns, which indicate that they play distinct functional roles. One isoform, GFAPδ, is expressed by proliferative radial glia in the developing human brain. In the adult human, GFAPδ is a marker for neural stem cells. However, it is unknown whether GFAPδ marks the same population of radial glia and astrocytes in the developing mouse brain as it does in the developing human brain. This study characterizes the expression pattern of GFAPδ throughout mouse embryogenesis and into adolescence. Gfapδ transcripts are expressed from E12, but immunohistochemistry shows GFAPδ staining only from E18. This finding suggests a translational uncoupling. GFAPδ expression increases from E18 to P5 and then decreases until its expression plateaus around P25. During development, GFAPδ is expressed by radial glia, as denoted by the co-expression of markers like vimentin and nestin. GFAPδ is also expressed in other astrocytic populations during development. A similar pattern is observed in the adolescent mouse, where GFAPδ marks both neural stem cells and mature astrocytes. Interestingly, the Gfapδ/Gfapα transcript ratio remains stable throughout development as well as in primary astrocyte and neurosphere cultures. These data suggest that all astroglia cells in the developing and adolescent mouse brain express GFAPδ, regardless of their neurogenic capabilities. GFAPδ may be an integral component of all mouse astrocytes, but it is not a specific neural stem cell marker in mice as it is in humans.

The likelihoods to become overweight (body mass index [BMI] .25 kg/m2 and obese (BMI .30 kg/m2 were assessed across the life course from the ages of 12 to 28 years.Subjects: Adolescent participants aged 12–17 years (n = 4119 identified in the National Longitudinal Survey of Youth 1997 at baseline were followed up to 2008.Results: Seven overweight risk groups (WG were detected for male and female samples respectively, of which five were closely related to each of the following five periods: (a middle-school ages (19.7% and 12.6% for male and female, respectively, (b high-school ages (11.4% and 13.6%, respectively, (c college ages (12.6% and 9.1%, respectively, (d post-college ages (11.8% and 10.0%, respectively, and (e work–family-formation ages (11.0% and 12.9%, respectively; two were nonperiod-specific groups: a permanent low-risk group for both sexes (27.3% for male, 36.4% for female, a growing-risk group for males (6.2%, and a self-limiting risk group for females (5.4%, with the likelihood increasing with age, which peaked at the age of 21 years, and then declined. Likewise, six obesity risk groups (OG were detected, of which four corresponded to the first four high-risk WG groups. The risk groups were relatively independent of race and educational attainment.Conclusions: Findings of this study imply that five risk groups for weight gain like five consecutive "tests" exist from middle-school period to work-and-family formation. Failure to pass any of these tests in the life course could lead to overweight or obese status. Further research needs to study life

  18. The influence of urban literature on African-American adolescent girls' sexual behaviors.

    2011-07-01

    Many African-American teenaged girls are reading urban literature. This genre of literature is known for its gritty portrayal of urban life and has themes of violence, promiscuity, substance abuse and misogyny. Although research has demonstrated that the portrayal of sex and violence in the media are influential on adolescent sexual behavior, to date there has been little research on the influence of "urban lit" on adolescent sexual risk behaviors. This qualitative study explores the influence of urban literature on the sexual risk behaviors among a group of African-American adolescent girls. Findings from this study suggest that African-American adolescent girls may be influenced by the sexual themes depicted in this genre of literature. Additional research is needed to gain a greater understanding of this phenomon.

    2013-01-01

    Adolescence is a critical period for neurodevelopment. Evidence from animal studies suggests that isolated rearing can exert negative effects on behavioral and brain development. The present study aimed to investigate the effects of adolescent social isolation on latent inhibition and brain-derived neurotrophic factor levels in the forebrain of adult rats. Male Wistar rats were randomly divided into adolescent isolation (isolated housing, 38–51 days of age) and social groups. Latent inhibition was tested at adulthood. Brain-derived neurotrophic factor levels were measured in the medial prefrontal cortex and nucleus accumbens by an enzyme-linked immunosorbent assay. Adolescent social isolation impaired latent inhibition and increased brain-derived neurotrophic factor levels in the medial prefrontal cortex of young adult rats. These data suggest that adolescent social isolation has a profound effect on cognitive function and neurotrophin levels in adult rats and may be used as an animal model of neurodevelopmental disorders.

  5. Pontine tegmental cap dysplasia: developmental and cognitive outcome in three adolescent patients

    Tortorella Gaetano

    2011-06-01

    Full Text Available Abstract Pontine Tegmental Cap Dysplasia (PTCD is a recently described, rare disorder characterized by a peculiar cerebellar and brainstem malformation. Nineteen patients have been reported to date, of which only one in the adolescent age, and data on the clinical, cognitive and behavioural outcome of this syndrome are scarce. Here we describe three adolescent patients with PTCD. All presented bilateral deafness and multiple cranial neuropathies, variably associated with skeletal, cardiac and gastro-intestinal malformations. Feeding and swallowing difficulties, that are often causative of recurrent aspiration pneumonias and death in the first years of life, completely resolved with age in all three patients. Neuropsychological assessment showed borderline to moderate cognitive impairment, with delay in adaptive functioning, visual-spatial and language deficits. Two of three patients also showed mild behavioural problems, although their overall socialization abilities were well preserved. Cochlear implantation in two patients significantly improved their relational and learning abilities. Fibre tractography confirmed the abnormal bundle of transversely oriented fibres forming the typical pontine "tegmental cap" and absence of decussation of the superior cerebellar peduncles, supporting the hypothesis that PTCD results from abnormal axonal guidance and/or migration. These data indicate that PTCD may have a favourable long-term outcome, with borderline cognitive deficit or even normal cognition and partially preserved speech.

    Packing therapy is an adjunct symptomatic treatment used for autism and/or catatonia. Here, we report the case of a 15-year-old boy with pervasive developmental disorder who developed catatonia. At admission, catatonic symptoms were severe and the patient required a feeding tube. Lorazepam up to 15 mg/day moderately improved the catatonic symptoms. On day 36 we added fluoxetine and on day 62 we added packing therapy (twice per week, 10 sessions). After three packing sessions, the patient showed a significant clinical improvement (Ppsychoanalysis and neuroscience. Indeed, better body representation following packing sessions, as shown in patient's drawing, paralleled clinical improvement, and supports the concept of embodied self. This concept may serve as a link between psychoanalysis and attachment theory, developmental psychology with the early description of "sense of self", and cognitive neurosciences that more and more support the concept of embodied cognition. Further clinical studies are necessary to clarify the efficacy and underlying mechanism of packing treatment and to understand how patient's experience may illustrate the concept of embodied self.

  8. Variation at genes influencing facial morphology are not associated with developmental imprecision in human faces.

    Directory of Open Access Journals (Sweden)

    Sonja Windhager

    Full Text Available Facial asymmetries are commonly used as a proxy for human developmental imprecision resulting from inbreeding, and thus reduced genetic heterozygosity. Several environmental factors influence human facial asymmetry (e.g., health care, parasites, but the generalizability of findings on genetic stressors has been limited in humans by sample characteristics (island populations, endogamy and indirect genetic assessment (inference from pedigrees. In a sample of 3215 adult humans from the Rotterdam Study, we therefore studied the relationship of facial asymmetry, estimated from nine mid-facial landmarks, with genetic variation at 102 single nucleotide polymorphism (SNP loci recently associated with facial shape variation. We further tested whether the degree of individual heterozygosity is negatively correlated with facial asymmetry. An ANOVA tree regression did not identify any SNP relating to either fluctuating asymmetry or total asymmetry. In a general linear model, only age and sex--but neither heterozygosity nor any SNP previously reported to covary with facial shape--was significantly related to total or fluctuating asymmetry of the midface. Our study does not corroborate the common assumption in evolutionary and behavioral biology that morphological asymmetries reflect heterozygosity. Our results, however, may be affected by a relatively small degree of inbreeding, a relatively stable environment, and an advanced age in the Rotterdam sample. Further large-scale genetic studies, including gene expression studies, are necessary to validate the genetic and developmental origin of morphological asymmetries.

  9. The influence of developmental environment on the evolution of olfactory foraging behaviour in procellariiform seabirds.

    2008-01-01

    The evolutionary origins of foraging behaviour by procellariiform seabirds (petrels, albatrosses and shearwaters) are poorly understood. Moreover, proximate factors affecting foraging ecology, such as the influence of environment on the development of sensory systems, have yet to be addressed. Here, we apply comparative methods based on current procellariiform phylogenies to identify associations between sensory modalities and the developmental environment that may underlie the evolution of complex foraging behaviour. We postulate that, for burrow-nesting species, smell is likely to dominate the sensory world of the developing chick. Alternatively, for ground-nesting species, chicks receive exposure to a range of visual, auditory and olfactory cues. We employ maximum likelihood to test models of correlated trait evolution between nesting habit and olfactory foraging style and to reconstruct the ancestral states of these characters when coded as binary states. Our results suggest that nesting behaviour has evolved in conjunction with foraging style. Based on this analysis, we propose that nesting on the surface was a life-history innovation that opened up a new developmental environment with profound effects on the foraging ecology of procellariiform seabirds.

    Szajnberg, Nathan Moses

    2012-12-01

    While vampires haunt contemporary American pop culture, the undead have populated psychoanalytic literature from Abraham's March 15, 1915 letter to Freud to today. PEP lists 439 psychoanalytic references to the undead (99 on zombies; 288 on vampires; 52 on werewolves). A selection of papers are cited, focusing on clinical cases, ethnography media and literature, even breast-feeding fantasized as blood sucking, associated with primitive dynamics. Previous works' libidinal, object relations, and dynamic perspectives on various "undeads" are summarized. This paper's contribution to the psychoanalytic literature is to examine the relationship of the three categories of undead both among each other and in their relation to the living. This paper presents a young adolescent's extensive play and fantasies about the undead, and his sophisticated intrapsychic model for the undead, developed prior to treatment, that kept him in psychical equilibrium, yet also kept him from feeling alive. This model has developmental implications for handling three types of transferences. Also, we may shed light on both contemporary preoccupation with the undead in contemporary American popular culture, and its endurance over time in Western culture. PMID:23253062

    This study investigated the growth trajectories and the relative relevance levels of nutrition, disease, and hormonal status at various developmental stages among children in adverse environments to provide population-based empirical evidence for the life history theory. Three years of longitudinal anthropometric data in 1-year intervals were obtained from 418 boys and girls aged 0 to 12 years at recruitment. Following the final measurement, the main survey, which included blood and feces sampling, 3-h interval food consumption recall surveys for energy and nutrient intakes and anthropometry, was performed. Blood and feces were used for detecting, respectively, anemia and hormonal (IGF-I and IGFBP-3) levels as well as intestinal helminthiasis (Ascaris, Trichuris, and hookworm). The major findings of this study are summarized as follows: 1) the growth velocity of the subject children lagged behind international standards during childhood and juvenility but caught up during early adolescence; 2) diseases, both intestinal helminths and anemia, had significant effects on growth in childhood but not at older ages; and 3) hormonal status significantly affected growth in the children, with its highest significance in early adolescence. A larger growth than international standards in early adolescence likely follows programmed hormonal mechanisms after the onset of puberty. The onset of puberty might be associated with adequate amounts of nutrient intake and be mediated by hormonal function, because the IGF-IZ score was significantly correlated with energy and protein intakes at the transitional period from juvenility to adolescence, when puberty occurs.

    In science, theories lend coherence to vast amounts of descriptive information. However, current diagnostic approaches in psychopathology are primarily atheoretical, emphasizing description over etiological mechanisms. We describe the importance of Polyvagal Theory toward understanding the etiology of emotion dysregulation, a hallmark of psychopathology. When combined with theories of social reinforcement and motivation, Polyvagal Theory specifies etiological mechanisms through which distinct patterns of psychopathology emerge. In this paper, we summarize three studies evaluating autonomic nervous system functioning in children with conduct problems, ages 4-18. At all age ranges, these children exhibit attenuated sympathetic nervous system responses to reward, suggesting deficiencies in approach motivation. By middle school, this reward insensitivity is met with inadequate vagal modulation of cardiac output, suggesting additional deficiencies in emotion regulation. We propose a biosocial developmental model of conduct problems in which inherited impulsivity is amplified through social reinforcement of emotional lability. Implications for early intervention are discussed.

  13. Developmental and Environmental Influences on Young Children's Vegetable Preferences and Consumption.

    Food intake patterns begin to be shaped at the earliest points in life. Early exposures and experiences are critical for the acceptance of some foods, particularly healthful foods such as vegetables, which often have a bitter component in their flavor profiles. In addition to repeated exposure to these foods, the quality and emotional tone of parent-child interactions are important in facilitating children's acceptance of vegetables. During early childhood, parents are challenged by children's developmental characteristics related to eating, such as the emergence of child neophobia, and by individual characteristics of the child that are more biologically based, including genetic predispositions to bitter taste and sensory sensitivities. Experimental studies consistently show that repeated exposure to novel and rejected familiar foods is the most powerful method to improve acceptance. However, the manner and persistence with which these exposures are performed are critical. Research investigating influences on children's vegetable acceptance and ingestion has focused on associations among availability, parent intakes, child neophobia, and the parental feeding response to children's reluctance to try and consume vegetables. Because young children's dietary intakes are low and below dietary recommendations, investigations have focused more on factors that impede children's vegetable acceptance, such as controlling feeding practices, than on positive influences. Research that addresses the multifaceted nature of these interactions among different levels of social-ecological environment, individual traits, parental feeding styles and practices, and socioeconomic influences and that uses longitudinal designs and complex statistical approaches is called for to ascertain more effective methods to improve children's vegetable acceptance.

  10. The developmental race between maturing host plants and their butterfly herbivore - the influence of phenological matching and temperature.

    Interactions between herbivorous insects and their host plants that are limited in time are widespread. Therefore, many insect-plant interactions result in a developmental race, where herbivores need to complete their development before plants become unsuitable, while plants strive to minimize damage from herbivores by outgrowing them. When spring phenologies of interacting species change asymmetrically in response to climate warming, there will be a change in the developmental state of host plants at the time of insect herbivore emergence. In combination with altered temperatures during the subsequent developmental period, this is likely to affect interaction strength as well as fitness of interacting species. Here, we experimentally explore whether the combined effect of phenological matching and thermal conditions influence the outcome of an insect-host interaction. We manipulated both developmental stages of the host plants at the start of the interaction and temperature during the subsequent developmental period in a model system of a herbivorous butterfly, Anthocharis cardamines, and five of its Brassicaceae host plant species. Larval performance characteristics were favoured by earlier stages of host plants at oviposition as well as by higher developmental temperatures on most of the host species. The probability of a larva needing a second host plant covered the full range from no influence of either phenological matching or temperature to strong effects of both factors, and complex interactions between them. The probability of a plant outgrowing a larva was dependent only on the species identity. This study demonstrates that climatic variation can influence the outcome of consumer-resource interactions in multiple ways and that its effects differ among host plant species. Therefore, climate warming is likely to change the temporal match between larval and plant development in some plant species, but not in the others. This is likely to have important

    2012-09-01

    Perceptions of maturational status may play an important role in facilitating caretaking and resources toward children expressing them. Previous work has revealed evidence that cues of cognitive immaturity foster positive perceptions in adults toward young children at a time during their lives when they are most dependent on adult care. In the current series of studies, the authors investigated when during development these biases emerge. They tested American and Spanish adolescents ranging from 10 to 17 years of age. Each participant rated a series of vignettes presenting different expressions of immature and mature thinking attributed to young children. Results revealed that older adolescents performed similarly to adults tested in previous studies (D. F. Bjorklund, C. Hernández Blasi, & V. A. Periss, 2010), rating positively expressions of supernatural thinking (e.g., animism) compared with other forms of immature cognition labeled as natural (e.g., overestimation). Both male and female participants 14 years and older favored children expressing the immature supernatural cognition on traits reflecting positive affect (e.g., endearing, likeable), while associating greater negative affect (e.g., sneaky, impatient with) with children expressing immature natural cognition. However, younger adolescents consistently rated all forms of immature thinking less positively than mature thinking, suggesting that a positive bias for some forms of immature thinking develops during adolescence. Based on an evolutionary developmental framework, the authors suggest that supernatural thinking may have a unique role in humans, fostering positive perceptions of young children in older adolescents (and adults) as they prepare themselves for the possible role of parenthood.

    Background: The cognitive function of children with either attention deficit hyperactivity disorder (ADHD) or learning disabilities (LDs) is known to be impaired. However, little is known about the cognitive function of children with comorbid ADHD and LD. The present study aimed to explore the cognitive function of children and adolescents with ADHD and learning difficulties in comparison with children with ADHD and healthy controls in different age groups in a large Chinese sample. Methods: Totally, 1043 participants with ADHD and learning difficulties (the ADHD + learning difficulties group), 870 with pure ADHD (the pure ADHD group), and 496 healthy controls were recruited. To investigate the difference in cognitive impairment using a developmental approach, all participants were divided into three age groups (6–8, 9–11, and 12–14 years old). Measurements were the Chinese-Wechsler Intelligence Scale for Children, the Stroop Color-Word Test, the Trail-Making Test, and the Behavior Rating Inventory of Executive Function-Parents (BRIEF). Multivariate analysis of variance was used. Results: The results showed that after controlling for the effect of ADHD symptoms, the ADHD + learning difficulties group was still significantly worse than the pure ADHD group, which was, in turn, worse than the control group on full intelligence quotient (98.66 ± 13.87 vs. 105.17 ± 14.36 vs. 112.93 ± 13.87, P ADHD symptoms, intelligence quotient, age, and gender. As for the age groups, the differences among groups became nonsignificant in the 12–14 years old group for inhibition (meaning interference of the Stroop Color-Word Test, 18.00 [13.00, 25.00] s vs. 17.00 [15.00, 26.00] s vs. 17.00 [10.50, 20.00] s, P = 0.704) and shift function (shifting time of the Trail-Making Test, 62.00 [43.00, 97.00] s vs. 53.00 [38.00, 81.00] s vs. 101.00 [88.00, 114.00] s, P = 0.778).

    Negative social experiences during adolescence increase the risk of psychiatric disorders in adulthood. Using “resident-intruder” stress, the present study aimed to investigate the effects of adolescent social defeat on emotional and cognitive symptoms associated with psychiatric disorders during adulthood and the effects of the developmental stage and social condition on this process. In Experiment 1, animals were exposed to social defeat or manipulation for 10 days during early adolescence (EA, postnatal days [PND] 28–37), late adolescence (LA, PND 38–47), and adulthood (ADULT, PND 70–79) and then singly housed until the behavioral tests. Behaviors, including social avoidance of the defeat context and cortically mediated cognitive flexibility in an attentional set-shifting task (AST), were assessed during the week following stress or after 6 weeks during adulthood. We determined that social defeat induced significant and continuous social avoidance across age groups at both time points. The mice that experienced social defeat during adulthood exhibited short-term impairments in reversal learning (RL) on the AST that dissipated after 6 weeks. In contrast, social defeat during EA but not LA induced a delayed deficit in extra-dimensional set-shifting (EDS) in adulthood but not during adolescence. In Experiment 2, we further examined the effects of social condition (isolation or social housing after stress) on the alterations induced by social defeat during EA in adult mice. The adult mice that had experienced stress during EA exhibited social avoidance similar to the avoidance identified in Experiment 1 regardless of the isolation or social housing after the stress. However, social housing after the stress ameliorated the cognitive flexibility deficits induced by early adolescent social defeat in the adult mice, and the social condition had no effect on cognitive function. These findings suggest that the effects of social defeat on emotion and cognitive

    2016-09-01

    Previous research with American Indian (AI) adolescent sexual risk behavior primarily focused on reservation-dwelling youth despite 70% of AIs living off Native lands. Using grounded theory methodology, I sampled 20 adolescent AI girls via talking circles and interviews to explore the perceptions of AI adolescent girls living in an urban, Midwest area about the influence of family and friends on their sexual behavior. Similar to research with other racial groups, participants cited their family and friends as a major influence. Five unique themes emerged related to family and friend influence. Urban-dwelling AI girls rely on their female family members and peers for information related to sex and receive varying messages from their networks of family and friends, which often overlap. AI youth have unique family groups yet have some similarities to other ethnic groups with regard to family and friend relationships that may allow for enhanced intervention development.

    Explaining how genetic factors contribute to associations between parenting and adolescent adjustment is an important next step in developmental research. This study examined the mediating effect of adolescent perceptions on these associations and the genetic and environmental influences underpinning the mediated relationship. Parent, adolescent, and observer ratings of parenting and adolescent adjustment were used in a genetically informative sample of 720 same-sex sibling pairs from 10 to 18 years old. Adolescent perceptions of parenting did significantly mediate a composite measure of parental conflict-negativity and adolescent antisocial behavior and depressive symptoms. The most substantial genetic contributions to the association between parenting and adolescent maladjustment were those mediated by adolescent perceptions. Once genetic and environmental contributions to adolescent perceptions of parenting were removed, shared environmental factors became more important for the remaining direct association.

    Full Text Available OBJECTIVE: To analyze the association between physical activity and social support from parents and friends on the physical activity level among adolescents. METHODS: Data from 2,361 adolescents (56.6% females; mean age 16.4; SD = 1.2, from public and private high schools were analyzed. The physical activity level of the adolescents, parents, and friends were measured through a questionnaire. Parents' and friends' support and self-efficacy were measured using two previously tested scales. Data analysis was performed usingthe structural equation modeling in IBM(r SPSS(r AmosTM 20.0. RESULTS: Physical activity of friends was directly associated with physical activity level of adolescents. Physical activity of the father was associated with their sons, and the physical activity of mother was associated with their daughters. An indirect association was identified between the physical activity of parents and friends with physical activity level of the adolescents, mediated by social support. Social support was directly associated with physical activity in adolescents of both genders and indirectly mediated by self-efficacy. CONCLUSIONS: Parents and friends have a social influence on adolescents' level of physical activity through the mechanism of behavior modeling or through social support, mediated by self-efficacy.

    Negative peer influence is one of the main risk factors associated with antisocial development among children and adolescents. In order to better understand these processes and to develop adequate preventive interventions, it is crucial that the factors that moderate peer influence are recognized. Such moderating variables can indicate who is at especially high risk for being negatively influenced by peers, and which conditions can buffer such a negative impact. In order to structure the exis...

    Friends are thought to influence adolescent drug use. However, few studies have examined the role of drugs in friendship selection, which is necessary to draw sound conclusions about influence. This study applied statistical models for social networks to test the contribution of selection and influence to associations in marijuana use among friends in two large high schools (N = 1,612; M age = 16.4). There was evidence for friend selection based on similar lifetime and current marijuana use a...

Patients and methods: Interviews were carried out with 20 adolescents with cystic fibrosis, investigating adolescent medical device use and experiences in relation to their personal and social lives and development through the adolescent years. The qualitative dataset was thematically examined using a content analysis method. Results: The results show that adolescent users of medical technologies want their independence and capabilities to be respected. Adolescent adherence to medical device use was associated with short- and long-term motivations, where older adolescents were able to comprehend the longer-term benefits of use against short-term inconvenience more acutely than younger adolescents. It was suggested that medical devices could provide a tool for communication with families and clinicians and could support adolescents as they take responsibility for managing their condition. Themes of “fitting into teenage life” and “use in the community” were associated with adolescents' needs to form their own identity and have autonomy. Conclusion: This study shows that adolescent needs regarding medical device use are complex. It provides evidence to suggest that devices designed inclusively for adolescents may lead to improved adherence and also facilitate transition through the adolescent years and achievement of adolescent goals.

    2014-02-01

    This study examines whether parents of children with developmental disorders are at risk of elevated allostatic load relative to control parents and whether positive affect moderates difference in risk. In all, 38 parents of children with developmental disorders and 38 matched comparison parents were analyzed. Regression analyses revealed a significant interaction between parent status and positive affect: parents of children with developmental disorders had lower allostatic load when they had higher positive affect, whereas no such association was evident for comparison parents. The findings suggest that promoting greater positive affect may lower health risks among parents of children with developmental disorders.

    Full Text Available The article examines the case of integration of an intellectually gifted adolescent with autism spectrum disorder in a general education school. It provides results of the applied behavioral analysis aimed at developing general learning skills. The child, diagnosed with Asperger’s syndrome at early school age, encountered difficulties related to the inability to study effectively at school in spite of the clear evidence of intellectual giftedness (including such motivational and instrumental preconditions as high levels of cognitive interest, verbal and abstract reasoning, and educability. The article reflects on the risks and advantages of the developmental work with the “twice exceptional” adolescent following an individual behavioral plan. Based on the results of the study, the article outlines the possible ways of forming the learning behavior skills: learning activity-based, communicative and organizational. The article discusses the necessity of further support of the “twice exceptional” adolescent based on an integrated approach with regard to the special learning needs of the intellectually gifted adolescent.

    2002-12-01

    Genetic and environmental influences in social attitudes were investigated in adopted and nonadopted children (N = 654) and their biological and adoptive relatives in the Colorado Adoption Project. Conservatism and religious attitudes were measured in the children annually from ages 12 to 15 and in the parents during the 12-year-old visit. Multivariate genetic model fitting indicated that both conservatism and religious attitudes are strongly influenced by shared-family environmental factors throughout adolescence. In contrast to previous findings from twin studies, which suggest that genetic influence on social attitudes does not emerge until adulthood, the present study detected significant genetic influence in conservatism as early as age 12. There was no evidence of genetic influence, however, on religious attitudes during adolescence.

  18. Influences on Understanding and Belief About the Origin of Species in Chinese and American Adolescents

    Science.gov (United States)

    Smith, Erin Irene

    Although beliefs about origins and evolutionary knowledge have been considered independent, research has suggested that both are influenced by cognitive constraints of psychological essentialism and teleology. Most research supporting these claims has been conducted with children from Western cultures; little is known about the psychological processes underpinning beliefs and knowledge about the natural world outside Western contexts or during adolescence. Claims about the universality of beliefs, knowledge, and the possible relationship between should be made after examining samples that differ in theoretically relevant ways from a typical Western sample, such as a Chinese sample in which religious explanations are rare or an adolescent sample in which brain development promotes the coordination of conflicting information. To examine how belief and knowledge are related in Western- and non-Western samples, as well as the factors that predict both independently, 238 Chinese (M = 15.85 years old, SD = .85 years; 36.6% male) and 277 American adolescents (M = 15.80 years, SD = 1.34 years; 51.6% male) were recruited from their high schools to participate. Adolescents completed a survey measuring beliefs about the origin of living and non-living exemplars, evolutionary knowledge, and variables that were likely to influence belief and knowledge such as science preference, epistemology, psychological essentialism, teleological reasoning, and religious beliefs. American adolescents were more creationist than Chinese adolescents. Chinese adolescents displayed more sophisticated evolutionary knowledge than American adolescents although overall performance was low. Finally, there was no relationship between belief and knowledge for American adolescents yet there was a small, positive relationship for Chinese adolescents such that adolescents who believed in creation also tended to demonstrate more evolutionary knowledge. Additional analyses employed mediation techniques to

    This article examines the relationship between parenting styles and the development of depressive symptoms among adolescents. We analyzed a nationally representative longitudinal data set of adolescents aged 12 to 14 in Taiwan. Results from growth mixture modeling revealed a nonlinear increase in the intensity of depressive symptoms between early and middle adolescence. More pronounced depressive symptoms in earlier years were also shown to be associated with more rapid development of similar symptoms later in adolescence. Perceived parenting styles, as manifest in parental warmth and harsh discipline, were categorized into 4 latent heterogeneous classes: attentive, reserved, austere, and conflicting. Adolescents living under austere parenting tend to report the most pronounced depressive symptoms from early to middle adolescence; however, the development of symptoms in this group was the slowest. We also discuss the role of harsh parenting in Chinese culture, as it pertains to the roles traditionally assumed by the father and mother. PMID:26168265

    2011-08-01

    This study had three goals: first, to investigate whether sexually explicit Internet material (SEIM) affects sexual risk behavior; second, to study whether these effects differ between adolescents and adults; and third, to analyze, separately for adolescents and adults, whether gender and age moderate an influence of SEIM on sexual risk behavior. The authors conducted a 2-wave panel survey among nationally representative random samples of 1,445 Dutch adolescents and 833 Dutch adults. SEIM use increased sexual risk behavior among adults, but not among adolescents. More specifically, moderator analyses showed that SEIM use increased sexual risk behavior only among male adults, but not among female adults. In the adolescent sample, no moderating gender effect occurred. Neither among adolescents nor among adults did age moderate the effects. Our study shows that SEIM may influence outcomes related to people's sexual health. It also suggests that male adults may present a potential risk group for adverse effects of SEIM. PMID:21476164

    Friendship tie choices in adolescent social networks coevolve simultaneously with youths' cigarette smoking and drinking. We estimate direct and multiplicative relationships between both peer influence and peer selection with salient parental factors affecting both friendship tie choice and the use of these 2 substances. We utilize 1 sample of 12 small schools and a single large school extracted from the National Longitudinal Study of Adolescent to Adult Health. Using a Stochastic Actor-Based modeling approach over 3 waves, we find: (a) a peer selection effect, as adolescents nominated others as friends based on cigarette and alcohol use levels across samples; (b) a peer influence effect, as adolescents adapted their smoking and drinking behaviors to those of their best friends across samples; (c) reciprocal effect between cigarette and alcohol usage in the small school sample; (d) a direct effect of parental support and the home smoking environment on adolescent friendship tie choice in the small school sample; (e) a direct effect of the home smoking environment on smoking across samples; (f) a direct effect of the home drinking environment on alcohol use across samples; and (g) a direct effect of parental monitoring on alcohol use across samples. We observed an interaction between parental support and peer influence in affecting drinking, and an interaction between the home drinking environment and peer influence on drinking, in the small school sample. Our findings suggested the importance of delineating direct and synergistic pathways linking network processes and parental influence as they affect concurrent cigarette and alcohol use.

    Full Text Available Shannon A Morrison, Carol J Dashiff, David E Vance School of Nursing, University of Alabama, Birmingham, AL, USA Abstract: Parental influence to promote autonomy and self-determination in their children as they grow up may also motivate them to exercise and eat healthily. Unfortunately, nutritious dietary consumption and physical activity frequency tend to decline during the adolescent years and reaches its lowest level as the adolescent nears adulthood. In this study of 132 freshman and sophomore college students, the influence of parental autonomy support on overall adolescents self-determination was examined to determine whether self-determination influences adolescents' motivation to engage in healthy diet and exercise behaviors. Utilizing hierarchical multiple regression analyses, parental autonomy support was not predictive of older adolescents' motivation for diet and exercise; however, study results did indicate that parental autonomy support remains highly influential in adolescent self-determination (F[2, 130] = 22.21; P = 0.001 during early college years and that in this sample, adolescent self-determination is predictive of motivation for diet (t = 2.21; P < 0.05, but not exercise. Findings suggest that parental autonomy support continues to influence adolescent internalization of attitudes and behaviors during latter adolescence, but may play a lessor role in motivation for specific health-related behaviors as the adolescent nears adulthood. A better understanding of health motivation antecedents of adolescents may facilitate nurses develop new approaches to health-promotion strategies.

    2014-01-01

    Background Evidence has been synthesized to determine hindering and facilitating factors associated with the work participation of adults with developmental dyslexia (DD), classified according to the International Classification of Functioning, Disability and Health (ICF). Methods A systematic literature review has been performed. Two search strings were used to determine the population and the context of work. The ICF was expanded with two subdivisions: one that made the environmental factors more work-related and a subdivision of personal factors. For data extraction the method known as qualitative metasummary was used and the manifest frequency effect size (MFES) for each category in the ICF was calculated. Results From 33 included studies 318 factors have been extracted and classified in the ICF. In the classification the frequency of occurrences and the consistency in direction (i.e., hindering or facilitating) have been made visible. The ICF categories with the highest MFES were mental functions with factors like feelings and emotions about dyslexia; activities like reading or writing/spelling; participation with factors like acquiring and keeping a job; social relationships at work where the attitudes and support of the employer and co-workers are important; working conditions with factors like the availability of assistive technology and accommodations on the job; and personal factors like self-disclosure and coping strategies. Conclusions In the context of work DD affects nearly all domains of functioning, mostly in a negative way. Within each domain the impact of DD increases over the course of life. To overcome that negative influence, many forms of adaptation, compensation, or coping are mentioned. Also notable is the lack of positive attitudes toward DD of the participants with DD—with the exception of the attitudes of teachers with DD—as well as on the part of colleagues, supervisors, and employers.

    Approximately 42 million adolescents aged 10-19 years, representing 13% of the population, resided in the United States in 2014 (1). Adolescence is characterized by rapid and profound physical, intellectual, emotional, and psychological changes (2), as well as development of healthy or risky behaviors that can last a lifetime. Parents have strong influence on their adolescent children's lives, and family-based programs can help parents support healthy adolescent development. Because schools are natural learning environments, implementing and improving school-based policies and programs are strategic ways to reinforce healthy behaviors and educate adolescents about reducing risky behaviors. Health care during adolescence should be tailored to meet the changing developmental needs of the adolescent while providing welcoming, safe, and confidential care. Parents, educators, care providers, public health officials, and communities should collaborate in fostering healthy environments for all adolescents, now and into the future. PMID:27491062

    Developmental-ecological models are useful for integrating risk factors across multiple contexts and conceptualizing mediational pathways for adolescent alcohol use, yet these comprehensive models are rarely tested. This study used a developmental-ecological framework to investigate the influence of neighborhood, family, and peer contexts on alcohol use in early adolescence (N = 387). Results from a multi-informant longitudinal cross-lagged mediation path model suggested that high levels of neighborhood disadvantage were associated with high levels of alcohol use 2 years later via an indirect pathway that included exposure to delinquent peers and adolescent delinquency. Results also indicated that adolescent involvement with delinquent peers and alcohol use led to decrements in parenting, rather than being consequences of poor parenting. Overall, the study supported hypothesized relationships among key microsystems thought to influence adolescent alcohol use, and thus findings underscore the utility of developmental-ecological models of alcohol use.

    Using a probability sample of 4,230 adolescents from grades 7-12, we used negative binomial regression to estimate the effects of peer and six family variables on the risk of adolescent drug use. Peer drug use had relatively strong effects of adolescent drug use. Parental drug attitudes, sibling drug use, and adult drug use had significant direct effects net of peer influences. In addition, they had significant indirect effects that were mediated by peer drug use. The influences of parental monitoring, attachment to mother, and attachment to father were statistically significant but relatively small. The findings applied to alcohol, binge drinking, cigarettes, marijuana, and other illicit drugs. Editors' Strategic Implications: The authors interpret their findings as being more consistent with social learning than social control theory. This research, although cross-sectional and limited to adolescents' self-reports, contributes to a growing literature on the direct and indirect influences of parents on their teens' substance use rates. It speaks to the need for school- and community-based prevention efforts to focus on families as well as peers. PMID:16228115

    2015-05-01

    Full Text Available Ten full time adolescent wheelchair users (ages 13-18 completed a total of three propulsion trials on carpet and tile surfaces, at a self-selected velocity, and on a concrete surface, at a controlled velocity. All trials were performed in their personal wheelchair with force and moment sensing wheels attached bilaterally. The first two trials on each surface were used as pre-intervention control trials. The third trial was performed after receiving training on proper propulsion technique. Peak Resultant Force, Contact Angle, Stroke Frequency, and Velocity were recorded during all trials for primary analysis. Carpet and tile trials resulted in significant increases in Contact Angle and Peak Total Force with decreased Stroke Frequency after training. During the velocity controlled trials on concrete, significant increases in Contact Angle occurred, as well as decreases in Stroke Frequency after training. Overall, the use of a training video and verbal feedback may help to improve short term propulsion technique in adolescent wheelchair users and decrease the risk of developing upper limb pain and injury.

    Involvement in physically active pursuits, such as sports, contributes to achieving and maintaining good emotional and physical health. The central goal of this article was to examine the longitudinal relationships between participation (i.e., time spent in the activities) in organized and informal sports contexts and motivational beliefs, and factors that might impact these relationships, such as developmental stage and gender. The data for the current study were drawn from the childhood and beyond longitudinal study, which utilized a cohort sequential design with data collected on three cohorts across four waves. The current study sample included 986 European American youth (51 % female), who t were mostly from working- and middle-class families. Self-report questionnaires were used to collect data from the youth about their participation in sports and their motivational beliefs (i.e., value and perceptions of competence) about this activity. Structural equation modeling was used to examine the relationships between participation and motivational beliefs across childhood and adolescence. The results provide some support for a model of reciprocal relationships between participation and motivational beliefs in organized and informal sports activities. These relationships between participation and motivational beliefs did not vary significantly based on developmental stage or by gender. Overall, the findings suggest that participation in organized and informal sports contexts may be fostered by supporting the development of positive motivational beliefs about the activities across developmental periods.

  18. Explanations for religious influence on adolescent sexual behavior in Brazil: direct and indirect effects

    Directory of Open Access Journals (Sweden)

    Ana Paula de Andrade Verona

    2011-06-01

    Full Text Available Religion is becoming an important and highly present factor in the lives of many adolescents and young adults in Brazil. In addition to creating more space for them to maintain close relationships and participate actively in a religious environment, some religions have promoted the dissemination of clearer standards and objectives, as well as punitive sanctions, with respect to many aspects of their younger followers' lives, including their sexual behavior. This article examines how religion can affect, direct and indirectly, the sexual behavior of Brazilian adolescents. The main objective of this study is to look for a connection between Christian Smith's theoretical framework, which suggests several mechanisms through which religion can influence the lives of American adolescents, and ethnographic studies conducted in Brazil, as well as quantitative works that have brought attention to social and demographic consequences of recent religious transformations. Even though there is limited empirical evidence as to how the mechanisms of religious involvement work in Brazil, this study concludes that each of Smith's pathways can also be used to explain potential effects of religion on sexual behavior of Brazilian adolescents. This research should encourage empirical studies on such effects in Brazil. Besides the importance of examining the impact of the recent transformations in Brazil religious landscape on demographic phenomena, this topic deserves further consideration from Brazilian demographers because religion is a primary socialization agent of adolescents, and sexual activity is a sphere of human behavior of high importance in its religious applicability.

    2005-03-01

    On two occasions separated by one year, Chinese adolescents with economic disadvantage in Hong Kong (N = 199) responded to instruments measuring perceived parental parenthood qualities (indexed by perceived parenting styles, support and help from parents, and conflict and relationship with the parents) and psychosocial adjustment (psychological well-being, substance abuse, and delinquency). Results showed that parental parenthood variables were concurrently associated with different measures of adolescent psychological well-being and problem behavior at Time 1 and Time 2. While paternal parenthood qualities at Time 1 predicted changes in existential well-being and delinquency in adolescent boys, but not in adolescent girls, at Time 2, maternal parenthood qualities at Time 1 predicted changes in the mental health and problem behavior in adolescent girls, but not in adolescent boys, at Time 2. There is no strong support for the thesis that adolescent adjustment influences perceived parental parenthood qualities over time. The present study suggests that the influences of fathers and mothers on the adjustment of Chinese adolescents experiencing economic disadvantage vary with the gender of adolescent children.

    Reniers, Renate L E P; Murphy, Laura; Lin, Ashleigh; Bartolomé, Sandra Para; Wood, Stephen J

    2016-01-01

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

    Close to 90% of U.S. adolescents now own or have access to a mobile phone, and they are using them frequently. Adolescents send and receive an average of over 60 text messages per day from their devices, and over 90% of adolescents now access the Internet from a mobile device at least occasionally. Many adults are asking how this constant connectivity is influencing adolescents' development. In this article, we examine seven commonly voiced fears about the influence of mobile technologies on adolescents' safety (e.g., cyberbullying and online solicitation), social development (e.g., peer relationships, parent-child relationships, and identity development), cognitive performance, and sleep. Three sets of findings emerge. First, with some notable exceptions (e.g., sleep disruption and new tools for bullying), most online behaviors and threats to well-being are mirrored in the offline world, such that offline factors predict negative online experiences and effects. Second, the effects of mobile technologies are not uniform, in that benefits appear to be conferred for some adolescents (e.g., skill building among shy adolescents), whereas risk is exacerbated among others (e.g., worsening existing mental health problems). Third, experimental and quasi-experimental studies that go beyond a reliance on self-reported information are required to understand how, for whom, and under what conditions adolescents' interactions with mobile technologies influence their still developing social relationships, brains, and bodies.

    Full Text Available Mariam Arain, Maliha Haque, Lina Johal, Puja Mathur, Wynand Nel, Afsha Rais, Ranbir Sandhu, Sushil Sharma Saint James School of Medicine, Kralendijk, Bonaire, The Netherlands Abstract: Adolescence is the developmental epoch during which children become adults – intellectually, physically, hormonally, and socially. Adolescence is a tumultuous time, full of changes and transformations. The pubertal transition to adulthood involves both gonadal and behavioral maturation. Magnetic resonance imaging studies have discovered that myelinogenesis, required for proper insulation and efficient neurocybernetics, continues from childhood and the brain's region-specific neurocircuitry remains structurally and functionally vulnerable to impulsive sex, food, and sleep habits. The maturation of the adolescent brain is also influenced by heredity, environment, and sex hormones (estrogen, progesterone, and testosterone, which play a crucial role in myelination. Furthermore, glutamatergic neurotransmission predominates, whereas gamma-aminobutyric acid neurotransmission remains under construction, and this might be responsible for immature and impulsive behavior and neurobehavioral excitement during adolescent life. The adolescent population is highly vulnerable to driving under the influence of alcohol and social maladjustments due to an immature limbic system and prefrontal cortex. Synaptic plasticity and the release of neurotransmitters may also be influenced by environmental neurotoxins and drugs of abuse including cigarettes, caffeine, and alcohol during adolescence. Adolescents may become involved with offensive crimes, irresponsible behavior, unprotected sex, juvenile courts, or even prison. According to a report by the Centers for Disease Control and Prevention, the major cause of death among the teenage population is due to injury and violence related to sex and substance abuse. Prenatal neglect, cigarette smoking, and alcohol consumption may also

    Sampled 1,004 eighth and tenth graders in 23 rural communities to examine peer influence and drug use. Students who perceived higher degree of drug use among friends and who received more information about drugs from friends used drugs more frequently. Findings support theory that peer pressure is related to drug abuse. (Author/NB)

  1. Brain structural correlates of risk-taking behavior and effects of peer influence in adolescents.

    Myoung Soo Kwon

    Full Text Available Adolescents are characterized by impulsive risky behavior, particularly in the presence of peers. We discriminated high and low risk-taking male adolescents aged 18-19 years by assessing their propensity for risky behavior and vulnerability to peer influence with personality tests, and compared structural differences in gray and white matter of the brain with voxel-based morphometry (VBM and diffusion tensor imaging (DTI, respectively. We also compared the brain structures according to the participants' actual risk-taking behavior in a simulated driving task with two different social conditions making up a peer competition situation. There was a discrepancy between the self-reported personality test results and risky driving behavior (running through an intersection with traffic lights turning yellow, chancing a collision with another vehicle. Comparison between high and low risk-taking adolescents according to personality test results revealed no significant difference in gray matter volume and white matter integrity. However, comparison according to actual risk-taking behavior during task performance revealed significantly higher white matter integrity in the high risk-taking group, suggesting that increased risky behavior during adolescence is not necessarily attributed to the immature brain as conventional wisdom says.

    2016-02-01

    This study aimed to identify distinct developmental trajectories (sub-groups of individuals who showed similar longitudinal patterns) of cannabis use among Australian adolescents, and to examine associations between trajectory group membership and measures of social and behavioural adjustment in young adulthood. Participants (n=852, 53% female) were part of the International Youth Development Study. Latent class growth analysis was used to identify distinct trajectories of cannabis use frequency from average ages 12 to 19, across 6 waves of data. Logistic regression analyses and analyses of covariance were used to examine relationships between trajectory group membership and young adult (average age: 21) adjustment, controlling for a range of covariates. Three trajectories were identified: abstainers (62%), early onset users (11%), and late onset occasional users (27%). The early onset users showed a higher frequency of antisocial behaviour, violence, cannabis use, cannabis-related harms, cigarette use, and alcohol harms, compared to the abstinent group in young adulthood. The late onset occasional users reported a higher frequency of cannabis use, cannabis-related harms, illicit drug use, and alcohol harms, compared to the abstinent group in young adulthood. There were no differences between the trajectory groups on measures of employment, school completion, post-secondary education, income, depression/anxiety, or alcohol use problems. In conclusion, early onset of cannabis use, even at relatively low frequency during adolescence, is associated with poorer adjustment in young adulthood. Prevention and intervention efforts to delay or prevent uptake of cannabis use should be particularly focussed on early adolescence prior to age 12. PMID:26414206

    This study was designed to describe the relationship between Internet addiction and parental problem drinking among early adolescents. Specific aims were to identify indirect, direct, and total influence of parental problem drinking on Internet addiction; to determine relative magnitudes of specific mediating effects of self-esteem, family function, anxiety-depression, and aggression in the total sample and the Internet addiction subgroup. The target population for this correlational study was early adolescents aged 11-12 years (n = 743) who attended elementary school in J City, South Korea. Study variables included the Internet addiction self-test scale, the Rosenberg Self-Esteem Scale, the Children of Alcoholics Screening Test, the Family Adaptability and Cohesion Evaluation Scale III, and the Korean version of the Child Behavior Checklist. Multiple-mediation analyses were performed. A significant association was observed between parental problem drinking and adolescents' Internet addiction. Only aggression significantly mediated the relationship between parental problem drinking and adolescents' Internet addiction in the total sample. When the Internet addiction group was analyzed separately as a subgroup, the mediation effect of aggression disappeared, and parental problem drinking had neither indirect nor direct association. However, the significant association of aggression with Internet addiction in the Internet addiction subgroup was two times as much as in the total sample. The findings suggested that parental problem drinking and aggression should be examined early to prevent development of Internet addiction in early adolescents. For those who already have developed Internet addiction, aggression should be the focal point for more effective intervention strategies.

    2015-11-01

    This study explores the rural environmental factors that influence adolescents' participation in physical activities (PA). Thirty-six indigenous adolescents, aged 13 to 17 years from rural communities of East Malaysia were involved in the photovoice procedures: photo-taking, selecting, contextualizing, and codifying themes. Despite being endowed with natural resources such as river, forest, hills, and so on, the adolescents and the community did not capitalize on these rich resources to promote and engage in PA. Poor maintenance of natural resources, the lack of pedestrian infrastructures and road safety, the lack of PA facilities, and negative perception of ancestors' agricultural activities were among factors that constrained adolescents' PA. Although basic amenities such as play spaces and pedestrian infrastructures are necessary to increase adolescents' PA, any intervention should make the most of the natural resources, which are cheaper, environment friendly, and sustainable.

    Fitzgerald, Amanda; Fitzgerald, Noelle; Aherne, Cian

    2012-08-01

    This systematic review investigated the relationship between peer and/or friend variables and physical activity among adolescents by synthesising cross-sectional, longitudinal, and experimental research conducted in the US. Seven electronic databases were searched to identify related articles published within the last 10 years and the articles reviewed included adolescents between 10 and 18 years. Studies reporting a measure of physical activity for adolescents and at least one potential peer and/or friend variable were included. Research demonstrated that peers and friends have an important role to play in the physical activity behavior of adolescents. Six processes were identified through which peers and/or friends may have an influence on physical activity including: peer and/or friend support, presence of peers and friends, peer norms, friendship quality and acceptance, peer crowds, and peer victimization. The theoretical significance of these results is assessed and the development of peer-related physical activity programs for adolescents is discussed.

    Full Text Available The association between early life factors and body mass index (BMI in adulthood has been demonstrated in developed countries. The aim of the present study was to assess the influence of early life factors (birth weight, gestational age, maternal smoking, and social class on BMI in young adulthood with adjustment for adult socioeconomic position. A cohort study was carried out in 1978/79 with 6827 mother-child pairs from Ribeirão Preto city, located in the most developed economic area of the country. Biological, economic and social variables and newborn anthropometric measurements were obtained shortly after delivery. In 1996, 1189 males from this cohort, 34.3% of the original male population, were submitted to anthropometric measurements and were asked about their current schooling on the occasion of army recruitment. A multiple linear regression model was applied to determine variables associated with BMI. Mean BMI was 22.7 (95%CI = 22.5-23.0. After adjustment, BMI was 1.22 kg/m² higher among infants born with high birth weight (³4000 g, 1.21 kg/m² higher among individuals of low social class at birth and 0.69 kg/m² higher among individuals whose mothers smoked during pregnancy (P < 0.05. The association between social class at birth and BMI remained statistically significant (P < 0.05 even after adjustment for adult schooling. These findings suggest that early life social influences on BMI were more important and were not reversed by late socioeconomic position. Therefore, prevention of overweight and obesity should focus not only on changes in adult life styles but also on factors such as high birth weight.

    Whole grain consumption is associated with reduced risk of chronic disease. One-fifth of UK adults and children do not consume any whole grains, and adolescents have low consumption rates. Factors affecting whole grain intake among adolescents are not well understood. This study examined the socio-economic, environmental, lifestyle and psychological factors likely to influence consumption and explored whether outcomes aligned with behavioural predictors proposed in the Reasoned Action Approach. Five focus groups explored young people's attitudes towards, knowledge and consumption of wholegrain foods, as well as barriers to, and facilitators of, consumption. Participants were male and female adolescents (n = 50) aged 11-16 years from mixed socioeconomic backgrounds and ethnicities, recruited through schools in the city of Leeds, UK. Focus groups were analysed using thematic analysis. Most participants had tried wholegrain food products, with cereal products being the most popular. Many recognised whole grain health benefits related to digestive health but not those related to heart disease or cancers. Several barriers to eating whole grains were identified including: difficulties in identifying wholegrain products and their health benefits; taste and visual appeal; and poor availability outside the home. Suggested facilitators of consumption were advertisements and educational campaigns, followed by improved sensory appeal, increased availability and choice, and tailoring products for young people. All constructs of the Theory of Reasoned Action were identifiable in the data, suggesting that the factors influencing whole grain intake in adolescents are well captured by this model. Study outcomes may inform research and health promotion to increase whole grain intake in this age group.

  19. Affiliative behavior, ultrasonic communication and social reward are influenced by genetic variation in adolescent mice.

    Directory of Open Access Journals (Sweden)

    Jules B Panksepp

    Full Text Available Social approach is crucial for establishing relationships among individuals. In rodents, social approach has been studied primarily within the context of behavioral phenomena related to sexual reproduction, such as mating, territory defense and parental care. However, many forms of social interaction occur before the onset of reproductive maturity, which suggests that some processes underlying social approach among juvenile animals are probably distinct from those in adults. We conducted a longitudinal study of social investigation (SI in mice from two inbred strains to assess the extent to which genetic factors influence the motivation for young mice to approach one another. Early-adolescent C57BL/6J (B6 mice, tested 4-6 days after weaning, investigated former cage mates to a greater degree than BALB/cJ (BALB mice, irrespective of the sex composition within an interacting pair. This strain difference was not due to variation in maternal care, the phenotypic characteristics of stimulus mice or sensitivity to the length of isolation prior to testing, nor was it attributable to a general difference in appetitive motivation. Ultrasonic vocalization (USV production was positively correlated with the SI responses of mice from both strains. Interestingly, several USV characteristics segregated with the genetic background of young mice, including a higher average frequency and shorter duration for the USVs emitted by B6 mice. An assessment of conditioned place preference responses indicated that there was a strain-dependent difference in the rewarding nature of social contact. As adolescent mice aged, SI responses gradually became less sensitive to genetic background and more responsive to the particular sex of individuals within an interacting pair. We have thus identified a specific, genetic influence on the motivation of early-adolescent mice to approach one another. Consistent with classical theories of motivation, which propose a functional

    Both sensation seeking and affiliation with deviant peer groups are risk factors for delinquency in adolescence. In this study, we use a sample of adolescent twins (n = 549), 13 to 20 years old (M age = 15.8 years), in order to test the interactive effects of peer deviance and sensation seeking on delinquency in a genetically informative design. Consistent with a socialization effect, affiliation with deviant peers was associated with higher delinquency even after controlling for selection effects using a co-twin-control comparison. At the same time, there was evidence for person-environment correlation; adolescents with genetic dispositions toward higher sensation seeking were more likely to report having deviant peer groups. Genetic influences on sensation seeking substantially overlapped with genetic influences on adolescent delinquency. Finally, the environmentally mediated effect of peer deviance on adolescent delinquency was moderated by individual differences in sensation seeking. Adolescents reporting high levels of sensation seeking were more susceptible to deviant peers, a Person × Environment interaction. These results are consistent with both selection and socialization processes in adolescent peer relationships, and they highlight the role of sensation seeking as an intermediary phenotype for genetic risk for delinquency.

    The present study examined: (1) gender and age differences of mean gender identity disorder (GID) trait scores in Japanese twins; (2) the validity of the prenatal hormone transfer theory, which predicts that, in dizygotic (DZ) twin pairs, twins with an opposite-gender co-twin more frequently exhibit GID traits than twins with a same-gender co-twin; and (3) the magnitude of genetic and environmental influences on GID traits as a function of age and gender. Data from 1450 male twin pairs, 1882 female twin pairs, and 1022 DZ male-female pairs ranging from 3 to 26 years of age were analyzed. To quantify individual variances in GID traits, each participant completed four questionnaire items based on criteria for GID from the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Our most important findings were: (1) Japanese females exhibited GID traits more frequently than males and Japanese children exhibited GID traits less frequently than adolescents and adults (among females, the prevalence was 1.6 % in children, 10 % in adolescents, and 12 % in adults; among males, the prevalence was 0.5, 2, and 3 %, respectively); (2) the data did not support the prenatal hormone transfer theory for GID traits; and (3) a large part of the variance for GID traits in children was accounted for by familial factors; however, the magnitude was found to be greater in children than in adolescents or adults, particularly among females. This study suggests that although the prevalence is likely to increase, familial effects are likely to decrease as individuals age. PMID:27507021

    Directory of Open Access Journals (Sweden)

    Monica Luciana

    2015-12-01

    Full Text Available Adolescent substance abuse is a major public health problem, particularly given the negative brain and behavioral consequences that often occur during and following acute intoxication. Negative outcomes appear to be especially pronounced when substance use is initiated in the early adolescent years, perhaps due to neural adaptations that increase risk for substance use disorders into adulthood. Recent models to explain these epidemiological trends have focused on brain-based vulnerabilities to use as well as neurodevelopmental aberrations associated with initiation of use in substance naïve samples or through the description of case-control differences between heavy users and controls. Within this research, adolescent alcohol and marijuana users have shown relative decreases in regional gray matter volumes, substance-specific alterations in white matter volumes, deviations in microstructural integrity in white matter tracts that regulate communication between subcortical areas and higher level regulatory control regions, and deficits in functional connectivity. How these brain anomalies map onto other types of youth risk behavior and later vulnerabilities represent major questions for continued research. This special issue addresses these compelling and timely questions by introducing new methodologies, empirical relationships, and perspectives from major leaders in this field.

Within this research, adolescent alcohol and marijuana users have shown relative decreases in regional gray matter volumes, substance-specific alterations in white matter volumes, deviations in microstructural integrity in white matter tracts that regulate communication between subcortical areas and higher level regulatory control regions, and deficits in functional connectivity. How these brain anomalies map onto other types of youth risk behavior and later vulnerabilities represent major questions for continued research. This special issue addresses these compelling and timely questions by introducing new methodologies, empirical relationships, and perspectives from major leaders in this field. PMID:26589541

    A significant gap remains in our understanding of the conditions under which parents' racial socialization has consequences for adolescents' functioning. The present study used longitudinal data to examine whether the frequency of communication between African American parents and adolescents (N = 504; 49 % female) moderates the association between parent reports of racial socialization (i.e., cultural socialization and preparation for bias) at 8th grade and adolescent reports of racial identity (perceived structural discrimination, negative public regard, success-oriented centrality) at 11th grade, and in turn, academic attitudes and perceptions. Parents' racial socialization practices were significant predictors of multiple aspects of adolescents' racial identity in families with high levels of communication, but they did not predict any aspects of adolescents' racial identity in families with low levels of communication. Results highlight the importance of including family processes when examining the relations between parents' racial socialization and adolescents' racial identity and academic attitudes and perceptions.

  15. Different Donor Cell Culture Methods Can Influence the Developmental Ability of Cloned Sheep Embryos.

    Directory of Open Access Journals (Sweden)

    LiBing Ma

    Full Text Available It was proposed that arresting nuclear donor cells in G0/G1 phase facilitates the development of embryos that are derived from somatic cell nuclear transfer (SCNT. Full confluency or serum starvation is commonly used to arrest in vitro cultured somatic cells in G0/G1 phase. However, it is controversial as to whether these two methods have the same efficiency in arresting somatic cells in G0/G1 phase. Moreover, it is unclear whether the cloned embryos have comparable developmental ability after somatic cells are subjected to one of these methods and then used as nuclear donors in SCNT. In the present study, in vitro cultured sheep skin fibroblasts were divided into four groups: (1 cultured to 70-80% confluency (control group, (2 cultured to full confluency, (3 starved in low serum medium for 4 d, or (4 cultured to full confluency and then further starved for 4 d. Flow cytometry was used to assay the percentage of fibroblasts in G0/G1 phase, and cell counting was used to assay the viability of the fibroblasts. Then, real-time reverse transcription PCR was used to determine the levels of expression of several cell cycle-related genes. Subsequently, the four groups of fibroblasts were separately used as nuclear donors in SCNT, and the developmental ability and the quality of the cloned embryos were compared. The results showed that the percentage of fibroblasts in G0/G1 phase, the viability of fibroblasts, and the expression levels of cell cycle-related genes was different among the four groups of fibroblasts. Moreover, the quality of the cloned embryos was comparable after these four groups of fibroblasts were separately used as nuclear donors in SCNT. However, cloned embryos derived from fibroblasts that were cultured to full confluency combined with serum starvation had the highest developmental ability. The results of the present study indicate that there are synergistic effects of full confluency and serum starvation on arresting fibroblasts in

    Full Text Available Given the public health importance of improving dietary behavior in chronic disease prevention in low- and middle-income countries it is crucial to understand the factors influencing dietary behavior in these settings. This study tested the validity of a conceptual framework linking individual and environmental factors to dietary behavior among Ecuadorian adolescents aged 10-16 years.A cross-sectional survey was conducted in 784 school-going Ecuadorian adolescents in urban and rural Southern Ecuador. Participants provided data on socio-economic status, anthropometry, dietary behavior and its determining factors. The relationships between individual (perceived benefits and barriers, self-efficacy, habit strength, and a better understanding of healthy food and environmental factors (physical environment: accessibility to healthy food; social environment: parental permissiveness and school support, and their association with key components of dietary behavior (fruit and vegetables, sugary drinks, breakfast, and unhealthy snack intake were assessed using structural equation modeling.The conceptual model performed well for each component of eating behavior, indicating acceptable goodness-of-fit for both the measurement and structural models. Models for vegetable intake and unhealthy snacking showed significant and direct effects of individual factors (perceived benefits. For breakfast and sugary drink consumption, there was a direct and positive association with socio-environmental factors (school support and parental permissiveness. Access to healthy food was associated indirectly with all eating behaviors (except for sugary drink intake and this effect operated through socio-environmental (parental permissiveness and school support and individual factors (perceived benefits.Our study demonstrated that key components of adolescents' dietary behaviors are influenced by a complex interplay of individual and environmental factors.

    It is increasingly recognized that in order to understand the complex phenomenon of antisocial behavior, interrelations between biological and social risk factors should be taken into account. In the current study, this biosocial approach was applied to examine the mediating role of deviant peers in longitudinal associations linking the level of hypothalamic-pituitary-adrenal (HPA) axis activity to aggression and rule-breaking. Participants were 425 boys and girls from the general population, who were assessed yearly at ages 15, 16, and 17. As a measure of HPA axis activity, cortisol was assessed at awakening, 30, and 60 min later (the cortisol awakening response, CAR). Participants, as well as their best friend, reported on their own aggressive and rule-breaking behavior, thereby allowing to assess bidirectional influences within friendships. Aggression was only predicted by a decreased cortisol level at awakening, and not by aggressive behavior of their friend. Decreased levels of cortisol at awakening predicted adolescents' rule-breaking, which subsequently predicted increased rule-breaking of their best friend. The latter was only found for adolescents who changed friends, as compared to adolescents with the same friend in every year. Gender differences were not found. These findings suggest that interrelations between biological and social risk factors are different for the development of aggression versus rule-breaking. Furthermore, decreased levels of HPA axis activity may represent a susceptibility to selecting deviant peers. PMID:23927935

    This study examined the relationship between the neighborhood food environment and the food purchasing behaviors among adolescents. Grade 7 and 8 students (n = 810) at 21 elementary schools in London, Ontario, Canada completed a questionnaire assessing their food purchasing behaviors. Parents of participants also completed a brief questionnaire providing residential address and demographic information. A Geographic Information System (GIS) was used to assess students' home and school neighborhood food environment and land use characteristics. Logistic regression analysis was conducted to assess the influence of the home neighborhood food environment on students' food purchasing behaviors, while two-level Hierarchical Non-Linear Regression Models were used to examine the effects of school neighborhood food environment factors on students' food purchasing behaviors. The study showed that approximately 65% of participants reported self-purchasing foods from fast-food outlets or convenience stores. Close proximity (i.e., less than 1 km) to the nearest fast-food outlet or convenience store in the home neighborhood increased the likelihood of food purchasing from these food establishments at least once per week by adolescents (p fast-food outlet density in both home and school neighborhoods was associated with increased fast-food purchasing by adolescents (i.e., at least once per week; p food environment surrounding children and youth's home and school.

    Abstract This study examined the global and current self-esteem levels of adolescents in a community sample of 550 secondary school students in Canada. A cross-sectional design and the survey method were used. Respondents' individual (age and gender) and environmental (cultural background, acculturating group, family circumstances, and perception of support) attributes were considered. Influences that promoted or challenged their current self-esteem were examined. Eighteen percent of respondents and 43.4% of respondents' parents were immigrants. When the Rosenberg Self-Esteem scale was used, 27.6% of respondents had the highest global self-esteem level; when the Current Self-Esteem scale was used, 12.7% had the highest current self-esteem level. A significant gender difference was found, with male adolescents having higher self-esteem. The results indicate that, although self-esteem promotion can benefit from lifestyle-oriented activities, its growth takes place in the larger context of adolescents' relationships, school-related experiences, achievements, and attitudes toward themselves. The study findings can contribute to mental health promotion strategies in multicultural and immigrant-receiving community settings.

    Evidence of negative stereotypes, prejudice and discrimination towards obese individuals has been widely documented. However, the effect of a larger body size on social network ties or friendship formations is less well understood. In this paper, we explore the extent to which higher body weight results in social marginalization of adolescents. Using data from a nationally representative sample of adolescents, we estimate endogeneity-corrected models including school-level fixed effects that account for bi-directionality and unobserved confounders to ascertain the effect of body weight on social network ties. We find that obese adolescents have fewer friends and are less socially integrated than their non-obese counterparts. We also find that such penalties in friendship networks are present among whites but not African-Americans or Hispanics, with the largest effect among white females. These results are robust to common environmental influences at the school-level and to controls for preferences, risk attitudes, low self-esteem and objective measures of physical attractiveness.

    Troubled sleep is a commonly cited consequence of adolescent drug use, but it has rarely been studied as a cause. Nor have there been any studies of the extent to which sleep behavior can spread in social networks from person to person to person. Here we map the social networks of 8,349 adolescents in order to study how sleep behavior spreads, how drug use behavior spreads, and how a friend's sleep behavior influences one's own drug use. We find clusters of poor sleep behavior and drug use that extend up to four degrees of separation (to one's friends' friends' friends' friends) in the social network. Prospective regression models show that being central in the network negatively influences future sleep outcomes, but not vice versa. Moreover, if a friend sleeps mediation analysis shows that 20% of this effect results from the spread of sleep behavior from one person to another. This is the first study to suggest that the spread of one behavior in social networks influences the spread of another. The results indicate that interventions should focus on healthy sleep to prevent drug use and targeting specific individuals may improve outcomes across the entire social network. PMID:20333306

    Diverse works have associated externalizing problem behavior with impulsivity, parental styles, and attitudes toward violence. The aim of this study is to analyze the association between these variables and externalizing behavior. A cross-sectional correlational design was used with a sample of 252 adolescents, aged between 12 and 15 years, from the general population. The results obtained indicate a significant association of externalization with high impulsivity, ingrained attitudes toward violence, and inconsistent parental styles, as well as gender and age differences. These results are discussed in relation with the influence of gender stereotypes and their implications in the development of attitudes toward violence.

    We investigated a unique way in which adolescent peer influence occurs on social media. We developed a novel functional MRI (fMRI) paradigm to simulate Instagram, a popular social photo-sharing tool, and measured adolescents' behavioral and neural responses to likes, a quantifiable form of social endorsement and potential source of peer influence. Adolescents underwent fMRI while viewing photos ostensibly submitted to Instagram. They were more likely to like photos depicted with many likes than photos with few likes; this finding showed the influence of virtual peer endorsement and held for both neutral photos and photos of risky behaviors (e.g., drinking, smoking). Viewing photos with many (compared with few) likes was associated with greater activity in neural regions implicated in reward processing, social cognition, imitation, and attention. Furthermore, when adolescents viewed risky photos (as opposed to neutral photos), activation in the cognitive-control network decreased. These findings highlight possible mechanisms underlying peer influence during adolescence. PMID:27247125

    For a long time autism spectrum and developmental disorders have not been well understood. Treatment and education for children with this disorders have been inappropriate in many ways. Although this fact was not obvious until many such children began to demonstrate secondary emotional disturbances including social withdrawal, social aggression, delinquency, domestic violence and momicide. This discourse describes advances in research and practice of clinical and psycho-neurological for autism spectrum in recent years. In addition, I suggest policies and measures for therapeutic education that will avoid secondary symptoms allowing these individuals to conduct their lives in socially independent directions.

We examined the influence of psychosocial factors on the trajectory of child/adolescent mental health problems (CAMHP over time. Methods A population-based sample of 6- to 13-year-olds with CAMHP was followed-up from 2002–2003 (Time 1/T1 to 2007–2008 (Time 2/T2, with 86 out of 124 eligible children/adolescents at T1 being reassessed at T2 (sample loss: 30.6%. Outcome: CAMHP at T2 according to the Child Behavior Checklist/CBCL’s total problem scale. Psychosocial factors: T1 variables (child/adolescent’s age, family socioeconomic status; trajectory of variables from T1 to T2 (child/adolescent exposure to severe physical punishment, mother exposure to severe physical marital violence, maternal anxiety/depression; and T2 variables (maternal education, child/adolescent’s social support and pro-social activities. Results Multivariate analysis identified two risk factors for child/adolescent MHP at T2: aggravation of child/adolescent physical punishment and aggravation of maternal anxiety/depression. Conclusions The current study shows the importance of considering child/adolescent physical punishment and maternal anxiety/depression in intervention models and mental health care policies.

    High rates of adolescent pregnancy, sexually transmitted infections, and unsafe abortions in Nigeria indicate the need for a greater understanding of factors that affect adolescent sexuality. The sexual health needs of adolescents remain poorly known and addressed particularly among vulnerable subpopulations like out-of-school adolescents. The objective of this study was to examine the sexual behavior of female out-of-school adolescents and to identify factors that influence their sexual behavior. This cross-sectional study was conducted among a representative sample of unmarried, out-of-school female adolescents (n = 332, mean age 17 y), selected using cluster sampling, who were working in a major market (Mushin) in Lagos, Nigeria. Data were collected using interviewer administered questionnaires. Many girls (43.7%) have had sexual intercourse. The mean age at initiation was 16 years. The main reason for initiation was curiosity. Risky sexual behavior and transactional sex was common. Nonconsensual sex was also reported. Sexual health knowledge was poor, and friends served as their main source of information on sexual health issues. Factors associated with the initiation of sexual activity were friends sexual behavior, the person adolescents reside with, parents marital status, availability of funds to meet basic needs, and watching pornography (p risky sexual behavior are exposed to sexual abuse, lack skills to resist pressure, and have limited access to credible reproductive health information. Appropriate interventions including provision of sexuality education and a supportive environment must be instituted to address their needs. PMID:19526700

    This study examined the relationship between ethnic pride, self-esteem and adolescent intentions to smoke cigarettes and engage in sexual intercourse. It also explored the influence of maternal levels of ethnic pride and self-esteem as indirect predictors of adolescent risk intentions. Middle school youth were randomly selected from six schools in the Bronx, NY. A total of 1,538 adolescents and their mothers were recruited. Mothers completed self-administered questionnaires about self-esteem and ethnic pride. Adolescents completed self-administered questionnaires about their intentions to engage in risk behaviors, as well as items about community connectedness, language spoken at home, self-esteem and ethnic pride. Results suggest that adolescent ethnic pride had protective effects on risk intentions through the mediator of self-esteem as well as independent of it. Maternal ethnic pride was associated with adolescent ethnic pride and, in turn, risk intentions, but the effect was weak in magnitude. Speaking Spanish at home was not significantly associated with ethnic pride. Both age and gender were related to ethnic pride, with ethnic pride diminishing as adolescents became older and females having higher levels of ethnic pride than males. PMID:19475509

    In 2 studies, the authors evaluated the role of parents, peers, and the media in body image and body-change strategies among adolescent boys and girls. The respondents for Study 1 (423 boys and 377 girls) completed the Body Image and Body Change Inventory (L. A. Ricciardelli & M. P. McCabe, 2002) and the Perceived Sociocultural Influences on Body Image and Body Change Questionnaire (M. P. McCabe & L. A. Ricciardelli, 2001b). Body mass index and age were also included in the analyses. Regression analyses demonstrated that sociocultural influences and feedback from the participant's best male friend were important predictors for all body-change strategies among boys. For girls, sociocultural influences and feedback from the participant's best female friend and mother were important predictors for body-change strategies. The most consistent predictor of weight loss, weight gain, and strategies to increase muscles was body-image importance. In Study 2, the authors examined the influence of the same sociocultural variables, as well as negative affect and puberty on body image and body-change strategies among a second group of 199 boys and 267 girls. The results demonstrated that a broad range of sociocultural influences predicted body-change strategies for boys and girls, with negative affect also having a unique influence for boys but not for girls. Puberty played a minor role, once other sociocultural variables were entered into the regression equation. The implications of these findings are discussed. PMID:12617344

    2016-06-01

    Full Text Available Adolescence has been characterized as a period of heightened sensitivity to social contexts. However, adolescents vary in how their social contexts affect them. According to neurobiological susceptibility models, endogenous, biological factors confer some individuals, relative to others, with greater susceptibility to environmental influences, whereby more susceptible individuals fare the best or worst of all individuals, depending on the environment encountered (e.g., high vs. low parental warmth. Until recently, research guided by these theoretical frameworks has not incorporated direct measures of brain structure or function to index this sensitivity. Drawing on prevailing models of adolescent neurodevelopment and a growing number of neuroimaging studies on the interrelations among social contexts, the brain, and developmental outcomes, we review research that supports the idea of adolescent neurobiological susceptibility to social context for understanding why and how adolescents differ in development and well-being. We propose that adolescent development is shaped by brain-based individual differences in sensitivity to social contexts – be they positive or negative – such as those created through relationships with parents/caregivers and peers. Ultimately, we recommend that future research measure brain function and structure to operationalize susceptibility factors that moderate the influence of social contexts on developmental outcomes.

    Peer influence processes have been documented extensively for a wide range of maladaptive adolescent behaviors. However, peer socialization is not inherently deleterious, and little is known about whether adolescents influence each other's prosocial behaviors, or whether some peers are more influential than others towards positive youth outcomes. This study addressed these questions using an experimental "chat room" paradigm to examine in vivo peer influence of prosocial behavior endorsement. A school-based sample of 304 early adolescents (55% female, 45% male; M(age) = 12.68) believed they were interacting electronically with same-gender grademates (i.e., "e-confederates"), whose peer status was experimentally manipulated. The participants' intent to engage in prosocial behaviors was measured pre-experiment and in subsequent "public" and "private" experimental sessions. Overall, the adolescents conformed to the e-confederates' prosocial responses in public; yet, these peer influence effects were moderated by the peer status of the e-confederates, such that youth more strongly conformed to the high-status e-confederates than to the low-status ones. There also was some evidence that these peer influence effects were maintained in the private session, indicating potential internalization of prosocial peer norms. These findings help bridge the positive youth development and peer influence literatures, with potential implications for campaigns to increase prosocial behaviors.

    Soft drink and fast food are energy dense foodstuffs that are heavily marketed to adolescents, and are likely to be important in terms of risk of obesity. This study sought to examine the influences on soft drink and fast food consumption among adolescents as part of a cross-sectional survey of 2,719 adolescents (aged 11-16) from 93 randomly selected schools in New South Wales, Australia. Students provided information on soft drink and fast food consumption, and responded to statements examining influences over consumption. Over half of the boys and more than one third of the girls reported drinking soft drink daily, and consumption peaked in Grade 8 students. A quarter of students reported choosing soft drinks instead of water or milk, and around 40% agreed that soft drink was usually available in their homes. Availability in the home and drinking soft drinks with meals was most strongly associated with consumption in all age groups. Fast food consumption was higher among boys than girls in all age groups. Convenience and value for money yielded the strongest associations with fast food consumption in boys, while preferring fast food to meals at home and preferring to "upsize" meals were most strongly associated with consumption in girls. Interventions to reduce consumption of soft drinks should target availability in both the home and school environment by removing soft drinks and replacing them with more nutritive beverages. Fast food outlets should be encouraged to provide a greater range of healthy and competitively priced options in reasonable portions. PMID:19786394

    Poor effortful control is a key temperamental factor underlying behavioral problems. The bidirectional association of child effortful control with both positive parenting and negative discipline was examined from ages approximately 3 to 13-14 years, involving five time points, and using data from parents and children in the Oregon Youth Study-Three Generational Study (N = 318 children from 150 families). Based on a dynamic developmental systems approach, it was hypothesized that there would be concurrent associations between parenting and child effortful control and bidirectional effects across time from each aspect of parenting to effortful control and from effortful control to each aspect of parenting. It was also hypothesized that associations would be more robust in early childhood, from ages 3 to 7 years, and would diminish as indicated by significantly weaker effects at the older ages, 11-12 to 13-14 years. Longitudinal feedback or mediated effects were also tested. The findings supported (a) stability in each construct over multiple developmental periods; (b) concurrent associations, which were significantly weaker at the older ages; PMID:27427809

    Although teachers and peers play an important role in shaping students' engagement, no previous study has directly investigated transactional associations of these classroom-based relationships in adolescence. This study investigated the transactional associations between adolescents' behavioral engagement, peer status (likeability and popularity), and (positive and negative) teacher-student relationships during secondary education. A large sample of adolescents was followed from Grade 7 to 11 (N = 1116; 49 % female; M age = 13.79 years). Multivariate autoregressive cross-lagged modeling revealed only unidirectional effects from teacher-student relationships and peer status on students' behavioral engagement. Positive teacher-student relationships were associated with more behavioral engagement over time, whereas negative teacher-student relationships, higher likeability and higher popularity were related to less behavioral engagement over time. We conclude that teachers and peers constitute different sources of influence, and play independent roles in adolescents' behavioral engagement.

    Full Text Available Recent studies suggest that obesity may be "contagious" between individuals in social networks. Social contagion (influence, however, may not be identifiable using traditional statistical approaches because they cannot distinguish contagion from homophily (the propensity for individuals to select friends who are similar to themselves or from shared environmental influences. In this paper, we apply the stochastic actor-based model (SABM framework developed by Snijders and colleagues to data on adolescent body mass index (BMI, screen time, and playing active sports. Our primary hypothesis was that social influences on adolescent body size and related behaviors are independent of friend selection. Employing the SABM, we simultaneously modeled network dynamics (friendship selection based on homophily and structural characteristics of the network and social influence. We focused on the 2 largest schools in the National Longitudinal Study of Adolescent Health (Add Health and held the school environment constant by examining the 2 school networks separately (N = 624 and 1151. Results show support in both schools for homophily on BMI, but also for social influence on BMI. There was no evidence of homophily on screen time in either school, while only one of the schools showed homophily on playing active sports. There was, however, evidence of social influence on screen time in one of the schools, and playing active sports in both schools. These results suggest that both homophily and social influence are important in understanding patterns of adolescent obesity. Intervention efforts should take into consideration peers' influence on one another, rather than treating "high risk" adolescents in isolation.

    Full Text Available BACKGROUND: In South Africa, the prevalence of oncogenic Human Papillomavirus (HPV may be as high as 64%, and cervical cancer is the leading cause of cancer-related death among women. The development of efficacious prophylactic vaccines has provided an opportunity for primary prevention. Given the importance of psycho-social forces in vaccine uptake, we sought to elucidate factors influencing HPV vaccination among a sample of low-income South African adolescents receiving the vaccine for the first time in Soweto. METHODS: The HPV vaccine was introduced to adolescents in low-income townships throughout South Africa as part of a nationwide trial to understand adolescent involvement in future vaccine research targeting human immunodeficiency virus (HIV. We performed in-depth semi-structured interviews with purposively-sampled adolescents and their care providers to understand what forces shaped HPV vaccine uptake. Interviews were recorded, transcribed, translated, and examined using thematic analysis. RESULTS: Of 224 adolescents recruited, 201 initiated the vaccine; 192 (95.5% received a second immunization; and 164 (81.6% completed three doses. In our qualitative study of 39 adolescent-caregiver dyads, we found that factors driving vaccine uptake reflected a socio-cultural backdrop of high HIV endemnicity, sexual violence, poverty, and an abundance of female-headed households. Adolescents exercised a high level of autonomy and often initiated decision-making. Healthcare providers and peers provided support and guidance that was absent at home. The impact of the HIV epidemic on decision-making was substantial, leading participants to mistakenly conflate HPV and HIV. CONCLUSIONS: In a setting of perceived rampant sexual violence and epidemic levels of HIV, adolescents and caregivers sought to decrease harm by seeking a vaccine targeting a sexually transmitted infection (STI. Despite careful consenting, there was confusion regarding the vaccine

    Learning from feedback is an important aspect of executive functioning that shows profound improvements during childhood and adolescence. This is accompanied by neural changes in the feedback-learning network, which includes pre-supplementary motor area (pre- SMA)/anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), superior parietal cortex (SPC), and the basal ganglia. However, there can be considerable differences within age ranges in performance that are ascribed to differences in strategy use. This is problematic for traditional approaches of analyzing developmental data, in which age groups are assumed to be homogenous in strategy use. In this study, we used latent variable models to investigate if underlying strategy groups could be detected for a feedback-learning task and whether there were differences in neural activation patterns between strategies. In a sample of 268 participants between ages 8 to 25 years, we observed four underlying strategy groups, which were cut across age groups and varied in the optimality of executive functioning. These strategy groups also differed in neural activity during learning; especially the most optimal performing group showed more activity in DLPFC, SPC and pre-SMA/ACC compared to the other groups. However, age differences remained an important contributor to neural activation, even when correcting for strategy. These findings contribute to the debate of age versus performance predictors of neural development, and highlight the importance of studying individual differences in strategy use when studying development.

Senior clinicians (SCs can influence the focus of dental care in the New South Wales (NSW Public Oral Health Services as their role is to provide clinical support and advice to therapists, advocate for their communities, and inform Local Health District (LHD managers of areas for clinical quality improvement. The objective of this study was to record facilitating factors and strategies that are used by SCs to encourage therapists to provide preventive care and advice to adolescent patients. Methods: In-depth, semistructured interviews were undertaken with 16 SCs from all of the 15 NSW LHDs (nine rural and six metropolitan. A framework matrix was used to systematically code data and enable key themes to be identified for analysis. Results: All SCs from the 15 NSW Health LHDs participated in the study. Factors influencing SCs' ability to integrate preventive care into clinical practice were: 1 clinical leadership and administrative support, 2 professional support network, 3 clinical and educational resources, 4 the clinician's patient management aptitude, and 5 clinical governance processes. Clinical quality improvement and continuing professional development strategies equipped clinicians to manage and enhance adolescents' confidence toward self-care. Conclusion: This study shows that SCs have a clear understanding of strategies to enhance the therapist's offer of scientific-based preventive care to adolescents. The problem

    Full Text Available Abstract Background Strict regulation of caste differentiation, at the molecular level, is thought to be important to maintain social structure in insect societies. Previously, a number of extrinsic and intrinsic factors have been shown to influence caste composition in termite colonies. One important factor is the influence of nestmates; in particular, soldier termites are known to inhibit hormone-dependent worker-to-soldier differentiation. However, soldier influences on nestmates at the molecular level are virtually unknown. Here, to test the hypothesis that soldiers can influence nestmate gene expression, we investigated the impact of four treatments on whole-body gene expression in totipotent Reticulitermes flavipes workers: (i juvenile hormone III (JHIII; a morphogenetic hormone, (ii soldier head extracts (SHE, (iii JHIII+SHE, and (iv live soldiers. Results Using quantitative-real-time PCR we determined the expression patterns of 49 previously identified candidate genes in response to the four treatments at assay days 1, 5, and 10. Thirty-eight total genes from three categories (chemical production/degradation, hemolymph protein, and developmental showed significant differential expression among treatments. Most importantly, SHE and live soldier treatments had a significant impact on a number of genes from families known to play roles in insect development, supporting previous findings and hypotheses that soldiers regulate nestmate caste differentiation via terpene primer pheromones contained in their heads. Conclusions This research provides new insights into the impacts that socio-environmental factors (JH, soldiers, primer pheromones can have on termite gene expression and caste differentiation, and reveals a number of socially-relevant genes for investigation in subsequent caste differentiation research.

  12. Living with Difference: Exploring the Social Self of Adolescents with Chronic Pain

    Directory of Open Access Journals (Sweden)

    Paula A Forgeron

    2013-01-01

    Full Text Available BACKGROUND: Chronic pain negatively affects an adolescent’s life; however, little is known about the social impact of chronic pain for adolescents. More is known about the general peer relationships of adolescents with chronic pain than their close friendships. Close friendships begin to take on more importance during adolescence as these relationships facilitate the development of an adolescent’s sense of personal identity and increasing independence from family influences. Thus, chronic pain may create friendship challenges for adolescents beyond those typically experienced during this developmental trajectory, which may negatively impact their abilities to secure social support.

    It is well-known that social influences affect consumption decisions. We used functional magnetic resonance imaging (fMRI) to elucidate the neural mechanisms associated with social influence with regard to a common consumer good: music. Our study population was adolescents, age 12-17. Music is a common purchase in this age group, and it is widely believed that adolescent behavior is influenced by perceptions of popularity in their reference group. Using 15-s clips of songs from MySpace.com, we obtained behavioral measures of preferences and neurobiological responses to the songs. The data were gathered with, and without, the overall popularity of the song revealed. Song popularity had a significant effect on the participants' likability ratings of the songs. fMRI results showed a strong correlation between the participants' rating and activity in the caudate nucleus, a region previously implicated in reward-driven actions. The tendency to change one's evaluation of a song was positively correlated with activation in the anterior insula and anterior cingulate, two regions that are associated with physiological arousal and negative affective states. Sensitivity to popularity was linked to lower activation levels in the middle temporal gyrus, suggesting a lower depth of musical semantic processing. Our results suggest that a principal mechanism whereby popularity ratings affect consumer choice is through the anxiety generated by the mismatch between one's own preferences and others'. This mismatch anxiety motivates people to switch their choices in the direction of the consensus. Our data suggest that this is a major force behind the conformity observed in music tastes in some teenagers.

    The impact of the social environment on healthy eating awareness results from complex interactions among physical, economic, cultural, interpersonal and individual characteristics. This study investigated the impact of social support and social influence on healthy eating awareness, controlling for socio-economic status, gender and age. Additionally, the mediating effect of self-regulation strategies was examined. A total of 2764 children and adolescents aged 10-17 from four European countries completed self-report measures on healthy eating awareness, social influence and the use of self-regulation strategies. Healthy eating awareness and the use of self-regulation strategies were more likely to occur among younger participants. An interaction between gender and age was related to the use of some self-regulation strategies; compared to girls, boys decreased the use of self-regulation strategies more from pre-adolescence to adolescence. Peer social influence was associated with more unhealthy eating in older participants. Results suggest a need to promote self-regulatory competences among young people in order to assist them with regulating their eating behaviours, especially in the presence of peers. Both school-based interventions and family-based interventions, focusing on self-regulation cognitions and social (peer) influence, could help children and adolescents to use self-regulatory strategies which are essential to eat healthier.

    2016-10-01

    Introduction Based on internal and external assets, the positive youth development approach aims to increase the capacity among adolescents to overcome challenges as they transition to adulthood. Developmental assets have been found to be positively associated with academic achievement, a variety of health promoting behaviors, and improved physical and mental health. The purpose of this exploratory study was to assess the long-term association between positive youth developmental assets with health risk and promoting behaviors. Method A continuous scale of developmental assets was created using 30 items from Wave I of the National Longitudinal Study of Adolescent to Adult Health, when participants were in 7th to 12th grades. Health behavior outcomes including cigarette use, substance use, fast food consumption, and physical activity were measured at both Wave III (age 18-26) and Wave IV (age 24-32). Path analysis was employed to assess the relationship between these observed measures. Results The well-fitted path model revealed associations between developmental assets with each health behavior at Wave III. Developmental assets indirectly influenced each health behavior and direct associations were observed between assets with substance use and physical activity at Wave IV. Conclusion Findings provide additional support for the developmental assets approach to adolescent health. Implications include Healthy People 2020 objectives related to tobacco and alcohol use and nutrition and physical activity. PMID:26462541

    Asthma is prevalent in Western countries, and recent explanations have evoked the actions of the gut microbiota. Here we show that feeding mice a high-fibre diet yields a distinctive gut microbiota, which increases the levels of the short-chain fatty acid, acetate. High-fibre or acetate-feeding led to marked suppression of allergic airways disease (AAD, a model for human asthma), by enhancing T-regulatory cell numbers and function. Acetate increases acetylation at the Foxp3 promoter, likely through HDAC9 inhibition. Epigenetic effects of fibre/acetate in adult mice led us to examine the influence of maternal intake of fibre/acetate. High-fibre/acetate feeding of pregnant mice imparts on their adult offspring an inability to develop robust AAD. High fibre/acetate suppresses expression of certain genes in the mouse fetal lung linked to both human asthma and mouse AAD. Thus, diet acting on the gut microbiota profoundly influences airway responses, and may represent an approach to prevent asthma, including during pregnancy. PMID:26102221

    Full Text Available OBJECTIVE: The influence of asthma, its severity levels and onset time on malocclusion occurrence were investigated. METHODS: The sample was composed by 176 children/adolescents, of both genders, aged 3 to 15 years, that were divided in two groups. The asthma group (AG enrolled 88 children/adolescents that were seen at the Breathe Londrina Program. The asthma-free group (AFG enrolled 88 preschool and school children recruited in 2 public schools. Malocclusion diagnosis was made according to WHO criteria (OMS, 1999. RESULTS: A higher prevalence in malocclusions in asthmatic patients in mixed dentition was observed when compared to controls (p0.05 and permanent dentition (p>0.05. A significant association was seen between asthma onset time and marked maxillary overjet (p<0.05, and open bite (p<0.05 in the mixed dentition, being both conditions more common among those that have presented the symptoms of asthma prior to 12 months of age. CONCLUSION: The results of this study indicate that the early manifestation of asthma at first year of life can cause dentofacial changes. Therefore, the prompt diagnostic of the illness, as well as the establishment of a proper therapy could improve the symptoms and chronic complications of asthma and also reduce its impact on craniofacial development.

  9. Influence of Parenting Practices on Eating Behaviors of Early Adolescents during Independent Eating Occasions: Implications for Obesity Prevention

    2015-10-01

    Full Text Available Among early adolescents (10–14 years, poor diet quality along with physical inactivity can contribute to an increased risk of obesity and associated biomarkers for chronic disease. Approximately one-third of United States (USA children in this age group are overweight or obese. Therefore, attention to factors affecting dietary intake as one of the primary contributors to obesity is important. Early adolescents consume foods and beverages during eating occasions that occur with and without parental supervision. Parents may influence eating behaviors of early adolescents during eating occasions when they are present or during independent eating occasions by engaging in practices that affect availability of foods and beverages, and through perceived normative beliefs and expectations for intake. Therefore, the purpose of this article was to describe the influence of parenting practices on eating behaviors in general and when specifically applied to independent eating occasions of early adolescents. This information may be helpful to inform parenting interventions targeting obesity prevention among early adolescents focusing on independent eating occasions.

    Environmental enrichment attenuates hippocampal synaptic injury induced by prenatal stress in offspring.However, the influence of hippocampal synaptic changes and regional differences in prenatal stress remains poorly understood.The present study induced stress in Sprague Dawley rats, which were at gestational age 13 19 days.Following weaning, the offspring were raised in an enriched environment to establish models of stress+enriched environment.Dendritic spine density and synaptophysin expression were detected in hippocampal neurons using Golgi staining and western blot analysis, respectively.Results showed that enriched environment increased dendritic spine density of apical dendrites in CA1 pyramidal cells and basal dendrites of granular cells in the outer layer of the dentate gyrus.In addition, hippocampal synaptophysin expression increased and the effects of prenatal stress on neuronal dendritic spines were reversed in adolescence.

    In order to address the mental health disparities that exist for Latino adolescents in the United States, psychologists must understand specific factors that contribute to the high risk of mental health problems in Latino youth. Given the significant percentage of Latino youth who are immigrants or the children of immigrants, acculturation is a key factor in understanding mental health among this population. However, limitations in the conceptualization and measurement of acculturation have led to conflicting findings in the literature. Thus, the goal of the current review is to examine and critique research linking acculturation and mental health outcomes for Latino youth, as well as to integrate individual, environmental, and family influences of this relationship. An integrated theoretical model is presented and implications for clinical practice and future directions are discussed. PMID:24794635

    Epidemiological and developmental studies showed that one of the obvious phenomena during adolescence is a marked increase in depressive symptoms. Behavioral genetic studies found that shared environmental influences account for the majority of the variance for children's symptoms while genetic factors are substantial for adolescent depressive symptoms. However, whether the results of behavioral genetic studies from Westerncountries can be generalized to adolescents in China with a collectivism culture remains unexplored. First, prevalence of depression varies dramatically across cultures with a lower rate in China than in other countries. Second, factors that are associated with depressive symptoms and the extent to which these factors are consequential for adolescents' mood are also different across cultures. Existing evidences showed that the quality of family relationships and grades in school had significantly stronger associations with depressive symptoms among Chinese youths than among U.S. youths. Third, genes that contribute to depressive symptoms have different frequencies in different races. Moreover, culture may moderate the expression of genes. Therefore, the first objective of the study was to examine the heritability of adolescent depressive symptoms for boys and girls in China, respectively.Results from the family study, the adoption study and the twin study suggest that adolescent depressive symptoms are heritable (range 15-80%). Moreover, empirical work showed that the relative contributions of genetic and environmental influences to depressive symptoms vary as a function of age. The second objective of the study was to extend previous ones by examining whether the heritability of depressive symptoms in early-adolescence was different from that in mid-adolescence. We hypothesized that the heritability of depressive symptoms in early adolescence was higher than that in middle adolescence according to the theory and empirical work. Depressive

    Despite accumulated experimental evidence of the negative effects of exposure to media-idealized images, the degree to which body image, and eating related disturbances are caused by media portrayals of gendered beauty ideals remains controversial. On the basis of the most up-to-date meta-analysis of experimental studies indicating that media-idealized images have the most harmful and substantial impact on vulnerable individuals regardless of gender (i.e., "internalizers" and "self-objectifiers"), the current longitudinal study examined the direct and mediated links posited in objectification theory among media-ideal internalization, self-objectification, shame and anxiety surrounding the body and appearance, dietary restraint, and binge eating. Data collected from 685 adolescents aged between 14 and 15 at baseline (47 % males), who were interviewed and completed standardized measures annually over a 3-year period, were analyzed using a structural equation modeling approach. Results indicated that media-ideal internalization predicted later thinking and scrutinizing of one's body from an external observer's standpoint (or self-objectification), which then predicted later negative emotional experiences related to one's body and appearance. In turn, these negative emotional experiences predicted subsequent dietary restraint and binge eating, and each of these core features of eating disorders influenced each other. Differences in the strength of these associations across gender were not observed, and all indirect effects were significant. The study provides valuable information about how the cultural values embodied by gendered beauty ideals negatively influence adolescents' feelings, thoughts and behaviors regarding their own body, and on the complex processes involved in disordered eating. Practical implications are discussed. PMID:25416025

    Adolescents living with HIV (ALHIV) face many psychosocial challenges, including HIV disclosure to others. Given the importance of socialization during the adolescent transition process, this study investigated the psychological and social factors influencing self-disclosure of own HIV status to peers. We examined social HIV self-disclosure to peers, and its relationship to perceived HIV-related stigma, self-efficacy to disclose, self-esteem, and social support among a sample of n = 582 ALHIV aged 13–17 years in Kampala, Uganda, and Western Kenya. Data were collected between February and April 2011. Among them, 39% were double orphans. We conducted a secondary data analysis to assess the degree of social disclosure, reactions received, and influencing factors. Interviewer-administered questionnaires assessed medical, socio-demographic, and psychological variables (Rosenberg self-esteem scale; self-efficacy to disclose to peers), HIV-related stigma (10-item stigma scale), and social support (family–life and friends). Descriptive, bivariate, and logistic regression analyses were performed with social self-disclosure to peers with gender as covariates. Almost half of ALHIV had told nobody (except health-care providers) about their HIV status, and about 18% had disclosed to either one of their friends, schoolmates, or a boy- or girlfriend. Logistic regression models revealed that having disclosed to peers was significantly related to being older, being a paternal orphan, contributing to family income, regular visits to the HIV clinic, and greater social support through peers. Low self-efficacy to disclose was negatively associated to the outcome variable. While social self-disclosure was linked to individual factors such as self-efficacy, factors relating to the social context and adolescents’ access to psychosocial resources play an important role. ALHIV need safe environments to practice disclosure skills. Interventions should enable them to make optimal use of

    Puberty is a very important process for adolescents. Physiological changes and body modifications lead to great vulnerability. This vulnerability is connected to the adolescent’s perceptions of the uncertainty of outcomes due to the transformation of their infant body into an adult one. This cross-sectional study aims to better understand whether body image perception and satisfaction influence self-esteem in a sample of Italian male and female adolescents. A total of 242 adolescents (120 mal...

    Adolescents' (N = 378) perceptions of and satisfaction with parenting styles, perceived parent-adolescent conflict, perceived frequency of parent-adolescent communication and related feelings, perceived parent-adolescent relationship, and mental health were assessed with rating scales and structured interviews on 2 occasions separated by 1 year. Results showed that the questionnaire and interview measures at each time could be grouped into 2 stable factors: Paternal Parenthood Qualities (PPQ) and Maternal Parenthood Qualities (MPQ). Although both factors generally had significant concurrent and longitudinal correlations with adolescents' mental health, PPQ at Time 1-predicted changes in adolescent life satisfaction, hopelessness, self-esteem, purpose in life, and general psychiatric morbidity at Time 2, whereas MPQ at Time 1 did not predict those changes. Adolescents' mental health at Time 1 was found to predict changes in MPQ but not PPQ at Time 2. Relative to maternal qualities, paternal qualities were generally found to exert a stronger impact on adolescent psychological well-being.

    Full Text Available The growing global production of zinc oxide nanoparticles (ZnONPs suggests a realistic increase in the environmental exposure to such a nanomaterial, making the knowledge of its biological reactivity and its safe-by-design synthesis mandatory. In this study, the embryotoxicity of ZnONPs (1–100 mg/L specifically synthesized for industrial purposes with different sizes, shapes (round, rod and surface coatings (PEG, PVP was tested using the frog embryo teratogenesis assay-Xenopus (FETAX to identify potential target tissues and the most sensitive developmental stages. The ZnONPs did not cause embryolethality, but induced a high incidence of malformations, in particular misfolded gut and abdominal edema. Smaller, round NPs were more effective than the bigger, rod ones, and PEGylation determined a reduction in embryotoxicity. Ingestion appeared to be the most relevant exposure route. Only the embryos exposed from the stomodeum opening showed anatomical and histological lesions to the intestine, mainly referable to a swelling of paracellular spaces among enterocytes. In conclusion, ZnONPs differing in shape and surface coating displayed similar toxicity in X. laevis embryos and shared the same target organ. Nevertheless, we cannot exclude that the physico-chemical characteristics may influence the severity of such effects. Further research efforts are mandatory to ensure the synthesis of safer nano-ZnO-containing products.

    Full Text Available Urbanization is a global problem with demographic trends. The urban heat island plays a dominant role in local climate systems. Despite existing efforts to understand the impacts of multiple urbanization factors on the urban heat island globally, very little is known about the attribution of urban heat island magnitude to urbanization in different locations or developmental phases. In this study, based on global land surface temperature data, urban spatial domain data, gross domestic product (GDP, and population data, we analyzed the influence of multiple urbanization factors on global surface urban heat island intensity (SUHII. We also tentatively compared the abovementioned factors between different regions across the globe, especially between China and the USA, the largest countries that are experiencing or have experienced rapid urbanization in recent decades. The results showed that global SUHII had remarkable spatial heterogeneity due to the geographical and socioeconomic variation between cities. There was a significant correlation between SUHII and population as well as GDP in global cities. Moreover, this study suggested that the impacts of population on SUHII might be stronger in the early stages of urbanization, and the GDP factor would become a critical factor at a certain development level. The urban area also had non-ignorable impacts on SUHII, while the correlation between SUHII and urban shape was relatively weak. All these may imply that the best approach to slow down SUHII is to find other solutions, e.g., optimize the spatial configuration of urban internal landscapes, when the urbanization reaches a high level.

    Full Text Available Recent work has established an association between overweight/obesity and sleep duration, suggesting that short sleep duration and timing of sleeping may lead to overweight. Most of these studies considered sleep-length rather than any other aspects associated with the sleep and wake rhythm, e.g. chronotype, which is a measure of timing of sleeping (‘when to sleep’; based on the midpoint of sleep. The objective of this study was to assess the influence of different factors of the sleep-wake cycle and of co-variates on the Body Mass Index in a cross-sectional questionnaire study. Nine hundred and thirteen pupils (406 boys, 507 girls from Southwestern Germany participated in this study. Mean age was 13.7 ± 1.5 (SD years and range was between 11 – 16 years. We found that chronotype (β = .079 and social jetlag (β = .063 showed a significant influence on Body Mass Index (BMI, while sleep duration did not. Social jetlag is the absolute difference between mid-sleep time on workdays and free days. Further, screen time (in front of TV, computer, β = .13 was positively related with BMI. Self-efficacy on nutrition (β = -.11, a psychological variable important in health-behaviour models, showed an influence with high scores on self-efficacy related to lower BMI. A high BMI was correlated with low fast-food consumption (β = -.12 suggesting that adolescents with high BMI may exert some control over their eating.
