Using a multi–method multi–trait prospective longitudinal approach, the current study tested five hypotheses related to the developmental–interactional model (i.e., Capaldi & Gorman–Smith, 2003) of intimate partner violence across time, romantic partners, and generations. We found significant stability in intimate partner violence from emerging adulthood to adulthood, even though over 80% of the targets in this sample changed romantic partners over this period. This suggests that intimate partner violence is a behavioral pattern that is recreated across subsequent relationships. After controlling for a host of individual risk factors as well as interparental psychological violence, the results show the continuity of psychological violence across adulthood. We also find that exposure to parent–to–child psychological violence during adolescence is a key predictor of later intimate partner violence. Because intimate partner violence was operationalized at the dyadic level, these findings hold for perpetration as well as victimization.
