The goal of this clinical trial is to conduct a preliminary evaluation of the ASSIST (Alcohol-focused Support of Survivors in Sororities Training) intervention in sorority chapters. ASSIST is a newly developed web-based intervention to increase peer support of sexual assault survivors and reduce encouragement of drinking to cope within social networks of sororities. To test whether the intervention is feasible and shows preliminary signs of working, a pilot cluster randomized trial will be conducted. Sorority chapters will be recruited and randomly assigned to an intervention condition or an assessment-only condition. Individuals within each sorority will be recruited and complete a norm documentation survey. One month later, participants will complete a baseline survey, and if assigned to the intervention condition, will then receive the web-based ASSIST intervention, which will include normative feedback on values and drinking, psychoeducation about sexual assault recovery and the role of alcohol, and skills training in behaviors that can be used to support survivors without or while moderating heavy drinking. All participants will complete online follow-up surveys at 1-, 3-, and 6-months post-intervention.
