Antisocial behavior and affiliation with deviant peers.

We examined the associations among gender, antisocial behavior, and peer-group affiliation in a high-risk sample of 401 homeless and matched housed adolescents (139 boys and 262 girls). The Diagnostic Interview Schedule for Children (Version 2.3, 1991; Costello, Edelbrock, Kalas, Kessler, & Klaric, 1982) yielded 2 measures of adolescent antisocial behavior: symptoms of conduct disorder and substance abuse or dependence.

Friendship and adjustment among adolescents.

This study investigated the relation of friendship and emotional adjustment in adolescents. Both quantitative (popularity, mutual friendships, and number of friends) and qualitative dimensions (perceived positive friendship quality and conflict) of friendship were used. Participants were 618, mostly European American, 8th-, 10th-, and 12th-graders.

A two-stage model of peer influence in adolescent substance use: individual and relationship-specific differences in susceptibility to influence.

A two-stage model of peer influence was proposed. The model served as a framework for examining individual and relationship-specific differences in susceptibility to influence. The two stages are (1) the acquisition of a peer context and (2) conforming to the behavior of a peer.
