In order to more fully understand the context and impact of intimate partner violence (IPV), it is important to make distinctions between different types of relationship aggression. As such, the current study longitudinally examines the differential effects of childhood, adolescent, and demographic factors on three different partner violence groups: those who experience bidirectional IPV, those who experience unidirectional IPV, and those who do not experience either form of IPV. Multinomial logistic regression results reveal that depressive symptoms and lower partner education predict bidirectional when compared to unidirectional IPV and nonviolence. In contrast, other risk factors such as illicit drug use are found to be predictors of unidirectional violence only, which reveals that the correlates of violence vary depending upon the type of IPV examined.
