Alcohol-related sexual violence remains a public health problem. Despite the popularity of sexual assault bystander intervention programs, these may be limited in addressing bystander intoxication because the effects of intoxication on intervening in a sexual assault are unknown. Therefore, we tested the effects of alcohol intoxication on the five steps of bystander intervention in a sexual assault vignette. Method: Young adults (N = 128; 50% women) were randomly assigned to consume alcohol (target blood alcohol concentration = 0.08%; n = 64) or a nonalcoholic control beverage (n = 64) in a barlaboratory. Next, participants were presented with a vignette describing events occurring in a convivial drinking context that ends with nonconsensual sexual behavior. Latané and Darley's bystander intervention model steps were assessed in a semistructured interview. Results: Participants in the control condition recalled the story more accurately (Step 1: notice the event) and reported greater risk/need for intervention (Step 2), but they did not differ on the latter three steps of bystander intervention compared with alcohol-condition participants. Intoxication effects were similar for men and women. Furthermore, risk/need for intervention (Step 2) partially mediated the effect of alcohol condition on personal responsibility (Step 3) and relative benefits versus costs from intervening (Step 4). Conclusions: Prevention programs should consider the effects of alcohol on detecting a sexual assault and the need to intervene. If intoxicated bystanders do not detect a sexual assault, then bystanders will not reach the crucial steps (i.e., taking responsibility for intervening; willingness and ability to intervene) required to intervene successfully.

Alcohol-related sexual assault among young adult women continues to present a public health concern. Social information-processing theory provides an organizing framework for understanding how alcohol intoxication can impair the processing of sexual assault risk cues and behavioral responding in sexual assault scenarios. The aim of the present article was to systematically review the extant research on the effects of alcohol intoxication on sexual assault risk information processing among young adult women. We selected relevant research through a systematic search of scientific databases, using key words related to young adult women, alcohol intoxication, and risk recognition, resulting in 14 independent research samples meeting all criteria. Studies used a variety of methods and dependent measures, precluding quantitative analysis of results. Thirteen of the 14 studies identified report at least partial support for intoxication impairing the attention to cues, interpretation of social information, or intended behavioral response in a hypothetical sexual assault scenario. Given some mixed findings, further research is warranted to identify contextual and individual differences related to risk detection and intended responding and to fully test other aspects of social information processing. Results have implications for improving alcohol-related sexual assault prevention programs by addressing the impact of alcohol intoxication on processing sexual assault risk information.

Objective: High rates of alcohol-related sexual assault among young adults represent a significant public health problem. Bystander intervention programs are a promising strategy to reduce sexual assault. However, little is known about how bystander intoxication may modify bystander intervention effectiveness. We examined the role of bystander intoxication and intoxication levels of the hypothetical victim and perpetrator on outcomes associated with Latané and Darley's (1970) steps of bystander intervention, which include noticing a situation, assessment of risk and need for intervention, taking personal responsibility for intervening, and selecting an intervention. Method: In a field setting, participants were recruited from a downtown area surrounded by drinking establishments. After providing informed consent, 327 participants (45% women) 21 to 29 years of age listened to 1 of 4 sexual assault vignettes (varied by victim and perpetrator intoxication), responded to questionnaires assessing outcomes related to steps of bystander intervention, and completed a field breathalyzer test. Results: Increased participant intoxication was related to decreased accuracy of situation recall and assessment of risk and need for intervention, but not ratings of personal responsibility to intervene, chosen intervention strategy, or confidence to intervene. Conclusions: Intoxication could influence how a bystander interprets a hypothetical nonconsensual sexual interaction at the level of accurate situation recall and risk assessment. If earlier steps of information processing are impaired by intoxication, later steps of intervention enactment may not occur successfully. Bystander intervention programming may consider incorporating training to overcome the impairing effects of intoxication for identifying harmful situations and choosing to intervene.

Findings suggest that differences in social information processing, specifically recognition of others' emotions, are associated with sexual assault risk detection. College prevention programs could incorporate emotional awareness strategies, particularly for men and women who are sexual assault survivors.

Findings suggest that the relationship between pregaming and alcohol-related problems is complex. Accordingly, future studies should utilize event-level methodology to understand how emotion regulation strategies influence alcohol-related problems. Further, clinicians should tailor alcohol treatments to help students increase their use of cognitive reappraisal and decrease their use of suppression.
