Bystander interventions for sexual assault promote third-party interference. People who endorse rape myths blame victims more and perpetrators less; consequently, rape myth acceptance (RMA) can impede helping behaviors toward sexual assault victims. Acute alcohol intoxication may exacerbate the effects of RMA on bystander intervention. In this study, we examined the influence of RMA-and potential moderating effect of acute alcohol intoxication-on predictors of bystander intervention. Young adults (N = 128) completed a survey in a lab setting, then consumed either an alcoholic or control beverage, read and listened to a fictional sexual assault scenario, and finally completed a semi-structured interview and postexperiment survey assessing their perceptions of the scenario. Using multivariate analysis of covariance (MANCOVA), we found people with higher RMA blamed the victim more and perpetrator less; they were also less likely to perceive responsibility to intervene for a sexual assault victim. Alcohol intoxication did not exacerbate these effects. That is, alcohol intoxication was not a context in which RMA was expressed more strongly. We recommend bystander programs continue to address RMA, specifically as a barrier to intervening.
