Explicit beliefs about aggression, implicit knowledge structures, and teen dating violence.

This study examined whether explicit beliefs justifying aggression and implicit knowledge structures theorized to facilitate aggression both contributed to between-subjects differences in teen dating violence (TDV). In addition, this research examined the contribution of explicit and implicit cognitions in the prediction of within-subjects changes in TDV over a 6-month period. Participants were 147 14- to 17-year-olds (48 % female) recruited from courts and agencies providing services to adolescents in trouble because of antisocial behavior. Teens completed a measure of explicit beliefs justifying aggression, a speeded word-completion task designed to measure aggressive content in implicit knowledge structures, and a measure of TDV. Measures were completed at 3 assessments, spaced 3 months apart. Results indicated that explicit beliefs justifying aggression and implicit knowledge structures theorized to facilitate aggression both contributed independently to between-subjects differences in TDV. However, only explicit beliefs about aggression were associated with within-subjects changes in TDV over the 6-month study period. These findings highlight the importance of considering both explicit and implicit cognitions in attempting to understand the perpetration of TDV.
