This study examines whether experiences of familial victimization and aggression are potential risk factors for dating violence in male and female teenage relationships. The authors compare 471 adolescents aged 12 to 19 in the care of a youth protection agency and from a community sample. Results show that adolescents carry negative childhood experiences of family violence into their intimate relationships in different ways, depending on gender and level of risk. Female adolescents who had been victimized by either of their parents were at greater risk for revictimization, but not aggression, within their dating relationships. High-risk adolescent males who reported childhood victimization were at a particularly high risk of being aggressive toward their girlfriends, especially if they were harshly disciplined by their father. The extent of aggression toward parents predicted aggression toward dating partners, particularly for girls. The authors discuss these findings in terms of prevention and early intervention efforts.
