Alcohol-free Social Activities Program

The Alcohol-Free Social Activities Program is a chapter-level behavioral intervention designed to increase the availability of and participation in rewarding social activities that do not involve alcohol among fraternity and sorority members. Participating chapters will receive a program toolkit containing guidance and procedures for planning and implementing alcohol-free social activities. Chapter leaders will select, plan, and implement activities for their members during the intervention period. The program is designed to increase opportunities for rewarding alcohol-free social experiences and strengthen social connection among chapter members.
