It has been argued that peers are the most important agent of adolescent socialization and, more specifically, that this socialization process occurs at the child-specific (or nonshared environmental) level (J. R. Harris, 1998; R. Plomin & Asbury, 2005). The authors sought to empirically evaluate this nonshared environmental peer influence…

Adolescence is a period of rapid developmental changes. Only in the early years of childhood do individuals experience such a brisk pace of change. However, all too often, out-of-school time (OST) programs do not recognize how quickly the needs and interests of adolescents shift along with their developmental changes. Program staff know--and…

This study explores the link between peer problems in school and contextual variations in negative mood and state self-esteem over a 5-day period. Fifth-grade children completed measures of mood and state self-esteem while they were at home in the morning and while they were at school each day, allowing for an examination of whether psychological…

This study examined adolescent developmental experiences and participation in extracurricular activities. Providing youth with multiple channels to nurture their development and acknowledge their interests and strengths can play a significant role in their holistic growth.

Although developing "teamwork" is commonly discussed as a goal for youth work, the meaning of teamwork is rarely articulated. Drawing from field research with programs for children and youth in a Chicago public housing community and with a community of Angolan refugee camps, this article demonstrates that teamwork has multiple potential…

Trajectories in bullying through adolescence were studied along with individual, family, and peer relationship factors. At the outset, participants' ages ranged from 10 to 14; 74% identified as European Canadian with the remainder from diverse backgrounds. With 8 waves of data over 7 years, 871 students (466 girls and 405 boys) were studied to…

This study examined the idea that expectations of behavior in hypothetical situations involving potential moral transgressions are related to emotion attributions relating to both moral and cost-benefit considerations. We asked younger (14 years 5 months) and older (16 years 1 month) female and male adolescents (a) to make predictions about the…

A diverse sample of 1,143 high school seniors and 182 students who were part of the same cohort but who left high school without graduating were interviewed during late adolescence (Time 1 [T1]) as well as 2 (Time 2 [T2]) and 4 years later (Time 3 [T3]). Perceived self-development, peer support, and prior levels of depressive symptoms (T2) were…

This paper investigates the growth of early adolescent self-esteem and self-concept as students progress through the middle level years (sixth through eighth grade). Based on mixed method longitudinal research conducted from 2004 to 2007, the study's findings suggest that this sample of 104 urban students' self-esteem changed most significantly…

Using a social constructionist perspective, we investigated the flexibility of early adolescents' (N = 80, 40 boys, 40 girls; M age = 13.14; SD = 0.65) masculinity and femininity as a function of the interpersonal context (same- or other-sex partner) and situational demands (co-operation or competition). Participants played a block-building game…

Articles in this special section illuminate progress, challenges, gaps, and future directions for theory and research concerned with peer relations and psychopathology. Advances reflect the emergence of developmental psychopathology, with its emphasis on systems theory, dynamic interactions of individuals in context, processes and change,…

Although the onset of illicit substance use during adolescence can hit parents abruptly like a raging flood, its origins likely start as a trickle in early childhood. Understanding antecedent factors and how they grow into a stream that leads to adolescent drug use is important for theories of social development as well as policy formulations to…
