Does marijuana use contribute to intimate partner aggression? A brief review and directions for future research. (October 2015) - Testa, Maria
Highlights: Marijuana use and IPA perpetration are positively associated in survey studies. Event-level studies fail to support a temporal effect of marijuana and IPA. Marijuana effects may be moderated by individual or couple differences. Additional studies of marijuana-using couples are needed to understand mechanisms. Abstract : Marijuana users are more likely to perpetrate intimate partner aggression (IPA) than non-users, yet the mechanism responsible for this association is unknown. Recent studies considering the association between episodes of marijuana use and episodes of IPA have failed to find evidence consistent with an acute effect of marijuana. Research gaps are highlighted and a heuristic model of marijuana's potential effects on IPA is presented. Research priorities include consideration of mediating mechanisms, moderating variables at the individual and couple level, and examination of acute effects of marijuana using daily report and EMA designs.
