Little attention has focused on how adolescents' perceptions of the pressure to be popular or socially preferred from parents, friends, and the media influence their engagement in face-to-face and cyber aggressive and prosocial behaviors. The present study examined these relationships among 857 seventh graders (M age = 12.19; 50.8% girls) from…

The purpose of this study was to explore grade-level differences (7th, 8th, and 9th) among junior high school students' perceptions of the effects of participation in physical education (PE) class on individual environmental stress. The role of physical activity as a stress reduction tool has been well documented. However, physical activity as a…

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…

Previous cross-national studies on social motivation among secondary students from individualistic societies such as Germany and Canada found four different motivation types (MT) varying in class size: (a) teacher-dependent MT, (b) peer-dependent MT, (c) teacher- and peer-dependent MT, and (d) teacher- and peer-independent MT. The current…

Under the integrated model of General Strain Theory (GST), the present study sought to examine whether delinquent peer association, social control, and negative emotion moderated the relations of distinctive cyberbullying roles with delinquency, as well as whether the moderating effects varied by gender among a nationally representative sample of…

Cognition plays a major role in the development of antisocial behavior. The aim of this study was to extend the current state of research regarding the mechanisms of negative peer influence in adolescence by testing whether aggregated classroom attitudes (injunctive norms) predict individual attitudes toward antisocial behavior and vice versa. For…

During adolescence, gender identity (GI) develops through a dialectic process of personal reflection and with input from the social environment. Peers play an important role in the socialization of gendered behavior, but no studies to-date have assessed peer influences on GI. Thus, the goal of the present study was to examine peer influences on…

It is now well known that adolescence is frequently marked by a decline in students' achievement motivation, which in turn is often associated with a decline in individual school self-concept. Less is known about the mediating role of socio-motivational support in the association between individual school self-concept and achievement motivation.…

Social goals are associated with behaviors and adjustment among peers. However, it remains unclear whether goals predict adolescent social development. We examined prospective associations among goals, physical and relational aggression, social preference, and popularity during middle school (N = 384 participants, ages 12-14 years). Agentic…

We examined (a) the relative importance of perceived social support from parents, peers, and teachers; (b) the consequences associated with different types of perceived social support; and (c) the mediation by achievement goals in the relationship between perceived social support and academic outcomes. We analyzed the first 3 waves of the Korean…

Adolescents may engage in risk behaviors that jeopardize their futures. Although adolescent risk-taking has long been attributed to faulty decision making, surprisingly little research has directly examined this link. This study examined the role of deliberative decision making (the tendency to consider options and consequences before making a…

Theory of Planned Behavior (Ajzen, 1991) was used to elicit salient behavioral, normative, and control beliefs of children without disabilities toward playing with a hypothetical peer with a disability in general physical education. Participants were 350 elementary and middle school students who completed two questionnaires. Questionnaires were…

Background: Physical aggression is an important issue in North American populations. The importance of students' social environments in the occurrence of physical aggression requires focused study. In this study, reports of physical aggression were examined in relation to social environment factors among national samples of students from Canada…

Objectives: By participating in this Stop the Tears teaching strategy, students will be able to: (1) analyze how alcohol and drug abuse could affect their lives as well as the lives of their friends and family and, (2) create a media message, such as a poster, pamphlet, poem, or song, in which alcohol and drug prevention is advocated specific to…

Increases in substance use prevalence among girls, as well as a lack of research conducted with urban girls of color, highlight the importance of understanding both predictors and outcomes of substance use abstinence (SUA) within this population. This study addresses gaps in SUA research through a longitudinal investigation conducted with urban…
