Across three waves, participants (N = 172, 91 female, 11-16 years across three waves; 439 data points) decided whether to pay money to learn their parents' or peers'…

This tribute to Albert Bandura shows how his lifetime of work on Social Cognitive Theory (SCT) has contributed to a greater understanding of school bullying. Managing children and adolescents' problematic behavior is a major challenge for schools with reducing bullying a priority. Here, the principles of SCT relevant to school bullying are…

This study examined how peer norms condition the effect of romantic involvement on adolescents' externalizing and internalizing problem behaviors. We hypothesized that, as a result of social control and social learning, adolescents who start a romantic relationship report more problem behavior when romantic involvement was not normative behavior…

This study examined age-related changes in friend similarity on delinquency to determine whether deviant behavior homophily peaks during mid-adolescence. A community sample of 1,663 male and 1,826 female Swedish youth from Grade 5 (M = 11.21 years) to Grade 10 (M = 16.25 years) provided self-reports of delinquency. Friendships were identified from…

There has been significant interest in examining the developmental factors that predispose individuals to chronic criminal offending. This body of research has identified some social-environmental risk factors as potentially important. At the same time, the research producing these results has generally failed to employ genetically sensitive…

Research suggests that sibling--peer connections are important for understanding adolescent problem behaviors. Using a novel behavioral genetic design, the current study investigated peer network overlap in 300 child--child pairs (aged 7-13 years) in 5 dyad types: monozygotic (MZ), dizygotic twins, full siblings (FSs), friend pairs, and virtual…

Adolescents' religious involvement occurs within a social context, an understudied aspect of which is relationships with peers. This longitudinal study assessed changes in religiosity over 1 year and explored the extent to which these were associated with their friends' religiosity and problem behavior. The first year sample included 1,010 (52.5%…

Research on school social dynamics suggests that antisocial behavior is often supported by peer group processes particularly during late childhood and adolescence. Building from a social interactional framework, this article explores how information on the social functions of aggressive and disruptive behavior may help to guide function-based…

Monitoring the Future (MTF) is designed to give sustained attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with and is conducted by a team of research professors at the University of Michigan's Institute for Social Research.

The data were collected from 995 middle school students in Nanjing, China. Both smoking experimentation and current smoking (smoking in the past 30 days) were assessed among the study sample. Psychosocial measures…

Substance use is a leading cause of preventable morbidity and mortality, and is in large part why people in the U.S. have the highest probability among industrialized nations of dying by age 50. Substance use deserves our sustained attention. It is also an important determinant of many social ills including child and spouse abuse, violence more…
