801 to 825 of 838Pubertal testosterone influences threat-related amygdala-orbitofrontal cortex coupling.
Growing evidence indicates that normative pubertal maturation is associated with increased threat reactivity, and this developmental shift has been implicated in the increased rates of adolescent affective disorders. However, the neural mechanisms involved in this pubertal increase in threat reactivity remain unknown. Research in adults indicates that testosterone transiently decreases amygdala-orbitofrontal cortex (OFC) coupling. Consequently, we hypothesized that increased pubertal testosterone disrupts amygdala-OFC coupling, which may contribute to developmental increases in threat reactivity in some adolescents. Hypotheses were tested in a longitudinal study by examining the impact of testosterone on functional connectivity. Findings were consistent with hypotheses and advance our understanding of normative pubertal changes in neural systems instantiating affect/motivation. Finally, …

Socioeconomic inequalities in adolescent health 2002-2010: a time-series analysis of 34 countries participating in the Health Behaviour in School-aged Children study.
Background: Information about trends in adolescent health inequalities is scarce, especially at an international level. We examined secular trends in socioeconomic inequality in five domains of adolescent health and the association of socioeconomic inequality with national wealth and income inequality.
Methods: We undertook a time-series analysis of data from the Health Behaviour in School-aged Children study, in which cross-sectional surveys were done in 34 North American and European countries in 2002, 2006, and 2010 (pooled n 492,788). We used individual data for socioeconomic status (Health Behaviour in School-aged Children Family Affluence Scale) and health (days of physical activity per week, body-mass index Z score [zBMI], frequency of psychological and physical symptoms on 0-5 scale, and life satisfaction scored 0-10 on the Cantril ladder) to examine trends in health and socioeco…

Dendritic remodeling in the adolescent medial prefrontal cortex and the basolateral amygdala of male and female rats.
There is recent evidence of continuing development throughout adolescence in two neural areas involved in emotion and cognition, the basolateral amygdala (BLN) and the medial prefrontal cortex (mPFC). Previous research from our laboratory has demonstrated a cellular loss in both of these brain regions in rats between postnatal day (P) 35 and 90. This study investigates dendritic changes in pyramidal neurons of the BLN and Layer 5 of the mPFC at P20 (juvenile), 35 (puberty), and 90 (adulthood) in hooded rats of both sexes. Dendritic branching and dendritic spines were quantified in Golgi-Cox impregnated tissue. Between P20 and 35, dendritic length and complexity, as well as the density of dendritic spines, increased in both structures. Between P35 and 90, dendritic spines in the mPFC neurons significantly decreased in both sexes, while a loss of basilar dendrites was only detected in fema…

Do guilt- and shame-proneness differentially predict prosocial, aggressive, and withdrawn behaviors during early adolescence?
In this short-term longitudinal study, we systematically examined the distinctiveness of guilt- and shame-proneness in early adolescents (N = 395, mean age = 11.8 years) in terms of differential relations with peer reported prosocial behavior, withdrawal, and aggression. Results from structural equation modeling indicated that guilt-proneness concurrently predicted more aggressive and less prosocial behavior as well as subsequent increases in prosocial behavior. Shame-proneness predicted subsequent decreases in prosocial behavior. Although girls reported a greater proneness to experience guilt and shame than boys, the associations between the two dispositional emotions and social behaviors were found to be similar across time and gender.

The development of moral emotions and decision-making from adolescence to early adulthood: a 6-year longitudinal study.
Adolescents' emotions in the context of moral decision-making repeatedly have been shown to predict actual behaviour. However, little systematic information on developmental change regarding these emotion expectancies has been available thus far. This longitudinal study investigated anticipated moral emotions and decision-making between the ages of 15 and 21 in a representative sample of Swiss adolescents (N = 1,258; 54 % female; M = 15.30 years). Anticipated moral emotions and decision-making were assessed through a semi-structured interview procedure. Using Bernoulli hierarchical linear modeling, it was found that positive feelings after a moral transgression (i.e., "happy victimizer" responses) decreased over time, whereas positive feelings after a moral decision (i.e., "happy moralist" responses) increased. However, this pattern was contingent upon the moral scenario presented. Syste…

Psychopathic-like traits in detained adolescents: clinical usefulness of self-report.
Studies have demonstrated that self-report tools can be used to reliably and validly examine psychopathic-like traits in adolescents. However, it is unclear if self-report instruments are still reliable and valid when confidentiality cannot be guaranteed, such as during routine assessments in juvenile detention centres. To address this issue, the current study used data from the routine mental health screening of 365 detained male adolescents (12-18 years) in two juvenile detention centres. With the intention of gaining insight in the clinical usefulness of self-reported psychopathic-like traits, we examined relations known from literature with emotional and behavioural features. Self-reported psychopathic-like traits, measured by the Youth Psychopathic Traits Inventory-Short version (YPI-S), were uniquely associated with substance abuse, anger/irritability, conduct problems and hyperact…

Connell LE, Francis LA (2014)MEDLINE-indexed journal, not yet read by usHealth psychology : official journal of the Division of Health Psychology, American Psychological Association32 citations Positive parenting mitigates the effects of poor self-regulation on body mass index trajectories from ages 4-15 years.
Objective: This study sought to determine whether parenting style moderates the effects of delay of gratification on body mass index (BMI) trajectories from ages 4-15 years.
Method: Longitudinal data were analyzed for 778 children drawn from the Study of Early Child Care and Youth Development. Parenting style (i.e., authoritative, authoritarian, permissive, and neglectful) was created from measures of mothers' sensitivity and expectations for self-control when children were age 4 years. Self-regulation was also measured at 4 years using a well-known delay of gratification protocol. BMI was calculated from measured height and weight at each time point. Mixed modeling was used to test the interaction of parenting styles and ability to delay gratification on BMI trajectories from 4-15 years.
Results: There was a significant interaction effect of parenting and ability to delay on BMI growth …

ADHD and risky sexual behavior in adolescents: conduct problems and substance use as mediators of risk.
Background: Recent studies have linked attention-deficit/hyperactivity disorder (ADHD) to elevated rates of risky sexual behavior (RSB) in adult samples. The current study tested whether ADHD symptoms were associated with RSB among adolescents, and examined comorbid conduct problems and problematic substance use as joint mediators of this association.
Methods: ADHD symptoms, conduct problems (oppositional defiant disorder/conduct disorder symptoms), problematic alcohol use (alcohol use disorder symptoms, alcohol use frequency), problematic marijuana use (marijuana use disorder symptoms, marijuana use frequency), and RSB were assessed among an ethnically diverse cross-sectional sample of adolescents (N = 115; mean age = 14.9 years) involved in the juvenile justice system.
Results: Bootstrapped mediation models revealed an initial association between ADHD symptoms and RSB that was accounte…

Psychosocial service use and unmet need among recently diagnosed adolescent and young adult cancer patients.
Background: Adolescents and young adults (AYAs) with cancer demonstrate biomedical risks and psychosocial issues distinct from those of children or older adults. In this study, the authors examined and compared the extent to which AYAs treated in pediatric or adult oncology settings reported use of, and unmet need for, psychosocial support services.
Methods: Within 4 months of initial cancer diagnosis, 215 AYAs ages 14 to 39 years (99 from pediatric care settings and 116 from adult care settings; 75% response rate) were assessed for reporting use of information resources, emotional support services, and practical support services. Statistical analyses derived odds ratios and 95% confidence intervals for service use and unmet needs after controlling for race, employment/school status, sex, relationship status, severity of cancer, treatment, and treatment-related side effects.
Results: AYA…

Adolescent neglect, juvenile delinquency and the risk of recidivism.
Victims of child abuse and neglect are at an increased risk of involvement with the juvenile justice and adult correctional systems. Yet, little is known about the continuation and trajectories of offending beyond initial contact with law enforcement. Neglect likely plays a critical role in continued offending as parental monitoring, parental rejection and family relationships are instrumental in explaining juvenile conduct problems. This study sought to determine whether neglect is associated with recidivism for moderate and high risk juvenile offenders in Washington State. Statewide risk assessments and administrative records for child welfare, juvenile justice, and adult corrections were analyzed. The sample was diverse (24 % female, 13 % African American, 8 % Hispanic, 5 % Native American) and included all moderate and high risk juvenile offenders screened by juvenile probation betwe…

Romeo RD (2013)MEDLINE-indexed journal, not yet read by usCurrent directions in psychological science215 citations The Teenage Brain: The Stress Response and the Adolescent Brain.
Adolescence is a time of many psychosocial and physiological changes. One such change is how an individual responds to stressors. Specifically, adolescence is marked by significant shifts in hypothalamic-pituitary-adrenal (HPA) axis reactivity, resulting in heightened stress-induced hormonal responses. It is presently unclear what mediates these changes in stress reactivity and what impacts they may have on an adolescent individual. However, stress-sensitive limbic and cortical brain areas that continue to mature during adolescence may be particularly vulnerable to these shifts in responsiveness. Consequently, perturbations of the maturing adolescent brain may contribute to the increase in stress-related psychological dysfunctions, such as anxiety, depression, and drug abuse, often observed during this stage of development. The purpose of this review is to describe the changes that occur…

Maternal and paternal parenting styles: unique and combined links to adolescent and early adult delinquency.
The present study examines the cross-sectional and longitudinal associations between fathers' and mothers' parenting styles and male and female delinquency using a sample of 330 Dutch families with a mid or late adolescent son or daughter (ages 14-22), followed across two measurement waves with a 5-year interval. Parenting styles of fathers and mothers were linked to delinquency. A significant parenting style by sex interaction was found: neglectful parenting was related to higher levels of delinquency in males and permissive parenting was linked to delinquency in females. A long term relationship was found between fathers' neglectful parenting style and delinquency in males. Furthermore, results revealed that levels of delinquency were the lowest in families with at least one authoritative parent and highest in families with two neglectful parents, indicating that the level of delinquen…

Antecedents and outcomes of joint trajectories of mother-son conflict and warmth during middle childhood and adolescence.
This study investigated the development of mother-son relationship quality from ages 5 to 15 in a sample of 265 low-income families. Nonparametric random effects modeling was utilized to uncover distinct and homogeneous developmental trajectories of conflict and warmth; antecedents and outcomes of the trajectory groups also were examined. Four conflict trajectory groups and 3 warmth trajectory groups were identified. Difficult temperament in early childhood discriminated both conflict and warmth trajectory group membership (TGM), and adult relationship quality in early childhood was related to warmth trajectories. In addition, conflict TGM differentiated youth antisocial behavior during adolescence, and warmth trajectories predicted adolescent peer relationship quality and youth moral disengagement. Implications for socialization processes are discussed.

Krettenauer T (2011)MEDLINE-indexed journal, not yet read by usThe Journal of genetic psychology11 citations The dual moral self: moral centrality and internal moral motivation.
In this study, the relationship between two aspects of the moral self, moral centrality and internal moral motivation, was analyzed. It is argued that these 2 aspects are conceptually distinct but nonetheless empirically related. Based on a cross-sectional study of 205 adolescents (M age = 14.83 years, SD = 2.21 years) it was found that moral centrality and internal moral motivation, even though substantially correlated, interacted in predicting moral emotion expectancies. Even though moral centrality was unrelated to adolescents' age it predicted a longitudinal increase in internal moral motivation over a 1-year interval. Overall, the findings call for a differentiation of moral centrality and internal moral motivation as 2 distinct but interrelated aspects of moral self-development that follow different developmental trajectories and are differentially related to age. At the same time,…

A meta-systems approach to evidence-based practice for children and adolescents.
Improving outcomes for children and adolescents with mental health needs demands a broad meta-systemic orientation to overcome persistent problems in current service systems. Improving outcomes necessitates inclusion of current and emerging evidence about effective practices for the diverse population of youth and their families. Key components of the meta-system for children with emotional or behavioral needs include families, cultural norms and values, and service sectors such as schools, pediatric health centers, specialty mental health systems, juvenile justice systems, child protection services, and substance use treatment systems. We describe each component of the meta-system, noting challenges to the provision of evidence-based practice (EBP) and highlighting ways to optimize outcomes. Our focus is on the inclusion of evidence-based assessment and interventions, including preventi…

Child maltreatment and adult cigarette smoking: a long-term developmental model.
Objective: To examine: (a) child maltreatment's association with young adult daily cigarette smoking, (b) variations in this association by gender, and (c) mediators of this association.
Methods: For all study participants (N = 1,125, 94% African American), data from multiple sources (e.g., child welfare records) were collected prospectively at child, adolescent, and young adult time points. Authors enlisted multivariate probit regression for objectives a and b versus exploratory and confirmatory mediation strategies for objective c.
Results: Maltreatment was significantly associated with daily cigarette smoking. Although not moderated by gender, this relation was fully mediated by adolescent indicators of family support/stability, social adjustment, and cognitive/school performance along with young adult indicators of educational attainment, life satisfaction, substance abuse, and crimi…

Obesity prevention in early adolescence: student, parent, and teacher views.
Background: Obesity is a significant health problem among today's youth; however, most school-based prevention programs in this area have had limited success. Focus groups were conducted with seventh- to eighth-grade students, parents, and teachers to provide insight into the development of a comprehensive program for the prevention of adolescent obesity: the Teen Eating and Activity Mentoring in Schools project (TEAMS).
Methods: Questions addressed (1) beliefs about the relationship between early adolescent behavior and health; (2) early adolescents' physical activity habits, preferences, influences, and barriers; (3) early adolescents' dietary habits, preferences, influences, and barriers; and (4) recommendations for interventions to promote physical activity and healthy eating in early adolescence.
Results: Qualitative analyses revealed that early adolescents had a good understanding …

Impact of behavioral inhibition and parenting style on internalizing and externalizing problems from early childhood through adolescence.
Behavioral inhibition (BI) is characterized by a pattern of extreme social reticence, risk for internalizing behavior problems, and possible protection against externalizing behavior problems. Parenting style may also contribute to these associations between BI and behavior problems (BP). A sample of 113 children was assessed for BI in the laboratory at 14 and 24 months of age, self-report of maternal parenting style at 7 years of age, and maternal report of child internalizing and externalizing BP at 4, 7, and 15 years. Internalizing problems at age 4 were greatest among behaviorally inhibited children who also were exposed to permissive parenting. Furthermore, greater authoritative parenting was associated with less of an increase in internalizing behavior problems over time and greater authoritarian parenting was associated with a steeper decline in externalizing problems. Results hig…

Preventive care for adolescents: few get visits and fewer get services.
Objective: Professional guidelines for adolescents recommend annual preventive visits with screening and anticipatory guidance for health-related behaviors. The objective of this study was to examine receipt of preventive services, including disparities in services received, by using a nationally representative sample of adolescents.
Methods: Using data from the 2001-2004 Medical Expenditure Panel Survey (ages 10-17; N = 8464), we examined receipt of preventive care visits and several measures of the content of care, based on caregiver's reports, among adolescents who received a preventive care visit during the past 12 months. Content of care outcomes included physical parameters measurement (height, weight, and blood pressure); receipt of anticipatory guidance (dental care, seat belts, helmets, exercise, healthy eating, and secondhand smoke exposure); and, for 12- to 17-year-olds, wheth…

Pathways from acculturation stress to substance use among latino adolescents.
The purpose of this study was to examine the link between acculturation stress and substance use among Latino adolescents. In-home interviews were completed with the participants at four time-points between 2005 and 2007. Path analysis was completed using longitudinal data from 286 Latino adolescents living in North Carolina and Arizona (65% foreign-born). Results indicate that acculturation stress influences family and friend relationships, which in turn affect adolescent mental health problems, and finally, substance use. Key mediators in the pathway from acculturation stress to substance use were parent-adolescent conflict, internalizing, and externalizing problems. Implications for practice and research have been discussed here.

Remembered parenting styles and adjustment in middle and late adulthood.
Background: Authoritative parenting is the parenting style often associated with positive outcomes for children and adolescents. This study considers whether remembered parenting styles in childhood predict multiple dimensions of functioning in adulthood.
Methods: We used the 1995 National Survey of Midlife Development in the United States data set (N = 2,232) to assess the association between parenting behaviors remembered from childhood-classified as authoritative, authoritarian, indulgent, and uninvolved-and psychological well-being, depressive symptoms, and substance abuse, in a subsample of mid- and later-life adults. Differences in outcomes by sex, race, and childhood socioeconomic status were also examined across parenting styles.
Results: Adults who remembered authoritative compared with authoritarian and uninvolved parents reported greater psychological well-being and fewer depr…

The effects of perceived parenting style on the propensity for illicit drug use: the importance of parental warmth and control.
Introduction and aims: Research in adolescents has shown that parental warmth and control are important factors in drug use. The present study focused upon investigating perceived parental warmth and control in a sample of post-adolescent ecstasy/polydrug users, and investigating their relationship to severity of drug use.
Design and methods: A total of 128 (65 male) ecstasy/polydrug users, 51 (17 male), cannabis-only users and 54 (13 male) non-users were recruited from a university population. All participants completed the parenting styles and drug use questionnaires.
Results: Compared to non-users, a greater proportion of ecstasy/polydrug users characterised their parents' style as neglectful. The modal style endorsed by non-users was authoritative. Those who rated their parents' style as authoritative had significantly lower lifetime consumption and average dose of ecstasy relative t…

Association between polymorphisms in the dopamine transporter gene and depression: evidence for a gene-environment interaction in a sample of juvenile detainees.
Previous research has generated examples of how genetic and environmental factors can interact to create risk for psychopathology. Using a gene-by-environment (G x E) interaction design, we tested whether three polymorphisms in the dopamine transporter gene (DAT1, also referred to as SLC6A3, located at 5p15.33) interacted with maternal parenting style to predict first-onset episodes of depression. Participants were male adolescents (N= 176) recruited from a juvenile detention center in northern Russia. As hypothesized, one of the polymorphisms (rs40184) moderated the effect of perceived maternal rejection on the onset of major depressive disorder, as well as on suicidal ideation. Further, this G x E interaction was specific to depression; it did not predict clinically significant anxiety. These results highlight the need for further research investigating the moderating effects of dopami…
