This study prospectively examined a social interactional model of husband marital aggression. Young couples were assessed at the time of their 1st marriage with respect to marital conflict styles, alcohol consumption, hostility, gender identity, perceived power inequity, and history of family violence. Couples were reassessed at their 1-year anniversary, and information concerning marital aggression was collected. Most of the constructs were prospectively related to husband aggression, but these relationships were largely mediated through marital conflict styles and husband alcohol consumption, which in turn were influenced by husband's hostility, gender identity, and perceived power inequity.
