Alcohol use and impulsivity are 2 known risk factors for intimate partner violence (IPV). The current study examined the independent and interactive effects of problematic drinking and 5 facets of impulsivity (i.e., negative urgency, positive urgency, sensation seeking, lack of premeditation, and lack of perseverance) on perpetration of physical IPV within a dyadic framework. Participants were 289 heavy drinking heterosexual couples (total N = 578) with a recent history of psychological and/or physical IPV recruited from 2 metropolitan U.S. cities. Parallel multilevel actor partner interdependence models were used and demonstrated actor problematic drinking, negative urgency, and lack of perseverance were associated with physical IPV. Findings also revealed associations between partner problematic drinking and physical IPV as well as significant Partner Problematic Drinking × Actor Impulsivity (Negative Urgency and Positive Urgency) interaction effects on physical IPV. Findings highlight the importance of examining IPV within a dyadic framework and are interpreted using the I3 metatheoretical model.
