Aggression toward female partners by at-risk young men: the contribution of male adolescent friendships.

Deviancy training was examined as a risk factor for physical and psychological aggression toward a female partner among boys and young men in the Oregon Youth Study. Hostile talk about women during videotaped male friendship interactions was hypothesized to indicate a process by which aggression toward women is reinforced within male peer networks. Both antisocial behavior and hostile talk were predicted to be associated with later aggression toward a female partner. Prospective developmental models were tested from 9-10 years of age through young adulthood. Findings indicated that the relation of deviant peer association in adolescence and later aggression toward a partner was mediated by antisocial behavior; observed hostile talk about women with male peers explained additional variance in aggression toward a partner.

Adolescent growth in new forms of problem behavior: macro- and micro-peer dynamics.

Longitudinal data from an at-risk sample were used to analyze individual linear trend scores for each of three new forms of problem behavior that emerges during the interval from age 10 through 18 years. Growth in substance use, health-risking sexual behavior and police arrests defined a latent construct for growth in adolescent problem behavior. A structural equation model (SEM) showed a significant path from early involvement with deviant peers to a latent construct for growth in new forms of antisocial behavior. A second SEM showed that the contribution of early involvement to later growth was mediated by a latent construct for deviancy training assessed at age 14 years. The relative rates of reinforcement for deviancy, amount of time spent with deviant peers, and deviancy level of the peer network defined a deviancy training construct that accounted for 53% of the variance in later growth in new forms.
