Adolescent Stress–Induced Epigenetic Control of Dopaminergic Neurons via Glucocorticoids

Environmental stressors during childhood and adolescence influence postnatal brain maturation and human behavioral patterns in adulthood. Accordingly, excess stressors result in adult-onset neuropsychiatric disorders. We describe an underlying mechanism in which glucocorticoids link adolescent stressors to epigenetic controls in neurons. In a mouse model of this phenomenon, a mild isolation stress affects the mesocortical projection of dopaminergic neurons in which DNA hypermethylation of the tyrosine hydroxylase gene is elicited, but only when combined with a relevant genetic risk for neuropsychiatric ...

Worldwide application of prevention science in adolescent health

The burden of morbidity and mortality from non-communicable disease has risen worldwide and is accelerating in low-income and middle-income countries, whereas the burden from infectious diseases has declined. Since this transition, the prevention of non-communicable disease as well as communicable disease causes of adolescent mortality has risen in importance. Problem behaviours that increase the short-term or long-term likelihood of morbidity and mortality, including alcohol, tobacco, and other drug misuse, mental health problems, unsafe sex, risky and unsafe driving, and violence ...

Adolescent Behavioral, Emotional, and Cognitive Engagement Trajectories in School and Their Differential Relations to Educational Success

The current study used a multidimensional approach to examine developmental trajectories of three dimension of school engagement (school participation, sense of school belonging, and self-regulated learning) from grades 7 to 11 and their relationships to changes in adolescents’ academic outcomes over time. The sample includes 1,148 African American and European American adolescents (52% females, 56% black, 34% white, and 10% others). As expected, the downward trajectories of change in school participation, sense of belonging to school, and self-regulated learning differed ...

Adolescent Males’ Awareness of and Willingness to Try Electronic Cigarettes

Purpose

Electronic cigarettes (e-cigarettes) are a new type of device that delivers vaporized nicotine without the tobacco combustion of regular cigarettes. We sought to understand awareness of and willingness to try e-cigarettes among adolescent males, a group that is at risk for smoking initiation and may use e-cigarettes as a “gateway” to smoking.

Methods

A national sample of 11–19-year-old males (n = 228) completed an online survey in November 2011. We recruited participants through their parents, who were members of ...

The Teenage Brain: Peer Influences on Adolescent Decision Making

Research efforts to account for elevated risk behavior among adolescents have arrived at an exciting new stage. Moving beyond laboratory studies of age differences in risk perception and reasoning, new approaches have shifted their focus to the influence of social and emotional factors on adolescent decision making. We review recent research suggesting that adolescent risk-taking propensity derives in part from a maturational gap between early adolescent remodeling of the brain’s socioemotional reward system and a gradual, prolonged strengthening of the ...

NetGirls: The Internet, Facebook, and body image concern in adolescent girls

Objective

The primary aim of the study was to examine the relationship between Internet exposure and body image concern in adolescent girls, with a particular focus on the social networking site of Facebook.

Method

A sample of 1,087 girls in the first two years (Years 8 and 9) of high school (aged 13–15 years) completed questionnaire measures of Internet consumption and body image concerns.

Results

The overwhelming majority of girls (95.9%) had access to the Internet ...

Impulsivity-related personality traits and adolescent alcohol use: A meta-analytic review

Heightened impulsivity has been identified as a risk marker for excessive and problematic alcohol use, particularly during adolescence when impulsive behaviour is elevated and alcohol use is often initiated. Recent advances in personality theory indicate that impulsivity comprises several discrete traits which may influence alcohol use through different pathways. This review used meta-analysis to assess the degree to which the impulsivity-related traits of lack of premeditation, lack of perseverance, sensation seeking, negative urgency, positive urgency, and reward sensitivity are associated ...

Adolescent Substance Use in the Multimodal Treatment Study of Attention-Deficit/Hyperactivity Disorder (ADHD) (MTA) as a Function of Childhood ADHD, Random Assignment to Childhood Treatments, and Subsequent Medication

Objective

To determine long-term effects on substance use and substance use disorder (SUD), up to 8 years after childhood enrollment, of the randomly assigned 14-month treatments in the multisite Multimodal Treatment Study of Children with Attention-Deficit/Hyperactivity Disorder (MTA; n = 436); to test whether medication at follow-up, cumulative psychostimulant treatment over time, or both relate to substance use/SUD; and to compare substance use/SUD in the ADHD sample to the non-ADHD childhood classmate comparison group (n = 261).

Method

Mixed-effects ...

Patterns of adolescent bullying behaviors: Physical, verbal, exclusion, rumor, and cyber

Patterns of engagement in cyber bullying and four types of traditional bullying were examined using latent class analysis (LCA). Demographic differences and externalizing problems were evaluated across latent class membership. Data were obtained from the 2005–2006 Health Behavior in School-aged Survey and the analytic sample included 7,508 U.S. adolescents in grades 6 through 10. LCA models were tested on physical bullying, verbal bullying, social exclusion, spreading rumors, and cyber bullying behaviors. Three latent classes were identified for each gender: All-Types ...

Inclusion of Children with Disabilities: Teachers’ Attitudes and Requirements for Environmental Accommodations

Teachers in general education are expected to cope with students with diverse needs. They might not always be ready or sufficiently supported to meet these challenges. The current study aims at identifying child, teacher and environmental barriers to inclusion. Specifically it addresses the importance of preschool teachers’ attitudes as the human environment factor that may facilitate inclusion of children with disability, and teachers’ major concerns about environmental accommodations that inclusion implies. The study assessed how teachers’ attitudes towards inclusion of ...
