Impulsivity and Reactive-Proactive Aggression as Mechanisms of Alcohol-Related Sexual Intimate Partner Violence Perpetration among Romantic Partners.

ABSTRACT

Background: Sexual intimate partner violence (S-IPV) commonly occurs within the contexts of committed romantic relationshops. Prior research has demonstrated the existence of a robust link between alcohol use and S-IPV. Despite this, few research studies have explored the etiological underpinnings of alcohol-related S-IPV perpetration, specifically. The present study examines the role of several key factors (i.e., problematic drinking, negative and positive urgency, proactive and reactive aggression) on S-IPV perpetration. Methods: Participants were 337 heavy drinking men and women in intimate relatinships who reported perpetrating some form of IPV toward their current partner within the past-year. A moderated-mediation model was used to determine how the key study variables interacted to predict S-IPV perpetration. Results: Results indicated that problematic drinking was positively correlated with both negative urgency and positive uregency. Findings also revealed that negative urgency, positive urgency, proactive aggression, and reactive aggression were all positively related to S-IPV perpetration. The indirect relationship between problematic drinking and S-IPV perpetration was mediated by positive urgency. Additionally, a significant main effect of proactive aggression on S-IPV perpetration was also detected. Conclusions: These findings suggest that impulsivity, specifically positive urgency, and proactive aggression may be under-appreciated constructs within the existing sexual aggression literature, and future research examining these variables as mechanisms explaining the association between the alcohol and S-IPV is warranted.
