The impact of men's alcohol consumption on perpetration of sexual aggression

Epidemiological and experimental literature examining the link between men's alcohol consumption and perpetration of sexual aggression is reviewed. The following are included in the review: (1) associational studies that examine the correlation between typical alcohol consumption and history of sexual aggression perpetration; (2) event-level studies that examine the impact of alcohol consumption at the time of sexual assault; and (3) experimental studies that consider the impact of administered alcohol on men's responses to a sexual aggression analog. Associational studies suggest a modest correlation between typical alcohol consumption and history of sexual aggression perpetration, but spurious effects may account for much of the relationship. Event-level studies offer mixed evidence in support of a relationship between alcohol consumption at the time of the sexually aggressive incident and severity of outcome. Experimental analog studies provide evidence of a proximal, pharmacological effect of alcohol on the likelihood of sexual aggression perpetration and more modest evidence supporting an alcohol expectancy effect. An integrative heuristic model of alcohol's distal and proximal effects on sexual aggression perpetration is proposed. Priorities for future research include greater specificity in measurement of sexual aggression, examination of alcohol's indirect effects on aggression through context, and consideration of mechanisms other than alcohol myopia in understanding alcohol's proximal effects.
