Covariation in the use of physical and sexual intimate partner aggression among adolescent and college-age men: a longitudinal analysis.

A longitudinal examination of male perpetration of physical aggression toward a romantic partner and its covariation with sexual aggression reveals a decline from adolescence through 4 years of college. Witnessing domestic violence and experiencing parental physical punishment increased the likelihood of physical aggression in adolescence, but not thereafter. Prior perpetration best predicted subsequent perpetration. Although adolescence was the time of greatest risk, the 2nd year in college was an additional time of increased risk. Furthermore, physical and sexual aggression covaried with each other in the sample at rates significantly greater than chance, indicating that covariation may be a unique form of perpetration. Witnessing domestic violence and experiencing parental physical punishment were associated with an increased likelihood of men committing both forms of intimate partner aggression in adolescence.
