"Marijuana use is associated with intimate partner violence perpetration among men arrested for domestic violence"
The title of this post is the title of this notable new research published in Translational Issues in Psychological Science. Here is the article's abstract:
Intimate partner violence (IPV) is a serious public health problem. Substance use, particularly alcohol, is a robust risk factor for IPV. There is a small but growing body of research demonstrating that marijuana use is positively associated with IPV perpetration. However, research on marijuana use and IPV has failed to control for other known predictors of IPV that may account for the positive association between marijuana use and IPV perpetration. Therefore, the current study examined whether marijuana use was associated with IPV perpetration after controlling for alcohol use and problems, antisocial personality symptoms, and relationship satisfaction, all known risk factors for IPV.
Participants were men arrested for domestic violence and court-referred to batterer intervention programs (N = 269). Findings demonstrated that marijuana use was positively and significantly associated with psychological, physical, and sexual IPV perpetration, even after controlling for alcohol use and problems, antisocial personality symptoms, and relationship satisfaction. Moreover, marijuana use and alcohol use and problems interacted to predict sexual IPV, such that marijuana use was associated with sexual IPV at high, but not low, levels of alcohol use and problems. These findings lend additional support to the body of research demonstrating that marijuana use is positively associated with IPV perpetration in a variety of samples. Results suggest that additional, rigorous research is needed to further explore why and under what conditions marijuana is associated with IPV perpetration.
