Advancing an Integrated Theory of Sexual Minority Alcohol-Related Intimate Partner Violence Perpetration

The link between alcohol use/abuse and partner violence attracted increasing research attention in the past decade. Some studies reported a null or weak association between alcohol use and intimate partner violence, whereas other studies reported a moderate or large association. Using a meta-analytic approach, the link between alcohol use/abuse and male-to-female partner violence as well as female-to-male partner violence was examined herein. The results indicate that there is a small to moderate effect size for the association between alcohol use/abuse and male-to-female partner violence and a small effect size for the association between alcohol use/abuse and female-to-male partner violence. For men only, several moderators were also examined and the magnitude of the effect sizes varied significantly as a function of the type of sample and type of alcohol measure selected. Specifically, there was a larger association of alcohol and aggression in clinical versus non-clinical samples and when measures assessed more severe alcohol problems.

To examine the evidence of association between intimate partner physical or sexual violence (IPV) victimization and alcohol consumption in women. We conducted a systematic review and meta-analysis of cross-sectional and longitudinal studies released before 6 June 2013. Studies providing an estimate of association between violence and alcohol consumption or alcohol use disorders were eligible for inclusion. Quality was assessed and random effects meta-analyses used to generate pooled odds ratios (OR) where appropriate. Higgins I(2) where P<0.10 was taken to indicate heterogeneity. Fifty-five studies providing 102 estimates of association met the inclusion criteria. Most estimates were not controlled for partner alcohol use and other key confounders. Seven longitudinal studies provided 12 estimates of the association between alcohol and subsequent IPV; nine of 12 estimates showed a direction of increased odds of subsequent IPV, pooled OR=1.27 [95% confidence interval (CI)=1.07-1.52], I(2) =0%, P=0.437. Nine longitudinal studies provided 15 estimates of association between IPV and subsequent alcohol use; 14 of 15 estimates showed a direction of increased odds of subsequent alcohol use, pooled OR=1.25 (95% CI 1.02-1.52), I(2)=0%, P=0.751. Cross-sectional studies showed an association between IPV and alcohol use, pooled OR=1.80, 95% CI 1.58-2.06, but with substantial heterogeneity, I(2)=60.8%, P<0.0001. Definition of alcohol use partly accounted for heterogeneity in cross-sectional estimates. There is a clear positive association between alcohol use and intimate partner physical or sexual violence victimization among women, suggesting a need for programming and research that addresses this link. However, the temporal direction of the association remains unclear. Longitudinal studies with multiple waves of data collection are needed. © 2013 Society for the Study of Addiction.
