Official incidents of domestic violence: types, injury, and associations with nonofficial couple aggression.

Official police reports of intimate partner violence (IPV) were examined in a community sample of young, at-risk couples to determine the degree of mutuality and the relation between IPV arrests and aggression toward a partner (self-reported, partner reported, and observed). Arrests were predominantly of the men. Men were more likely to initiate physical contact, use physical force, and inflict injuries than women, although few injuries required medical attention. In the context of nonofficial aggression toward a partner, overall, women had higher levels of physical and psychological aggression compared to men, and levels of severe physical aggression did not differ by gender. Couples with an IPV arrest were more aggressive toward each other than couples with no IPV arrests; however, nonofficial levels of aggression were not higher for men than for women among couples experiencing an IPV incident.
