This study examined associations between interparental conflict and adolescents' romantic relationship conflict. High school seniors (N = 183) who lived with married parents completed questionnaires about their parents' marriage and their own romantic relationships. A subset of 88 adolescents was also observed interacting with their romantic partners. Adolescents' perceptions and appraisals of interparental conflict were related to the amount of conflict in romantic relationship and adolescents' conflict styles. Adolescents' appraisals of interparental conflict (i.e., self-blame, perceived threat) moderated many of the associations between interparental conflict and conflict behavior with romantic partners. The patterns of moderated effects differed by gender. These findings suggest that the meanings boys and girls ascribe to interparental conflict are important for understanding how family experiences contribute to the development of romantic relationships.
