What this trial studies
The trial tests a behavioral intervention that offers alcohol-free social activities through Greek chapters at a university, aiming to reduce heavy episodic drinking and its negative consequences. It uses a pre-post design over two academic years to assess feasibility, acceptability, and changes in drinking outcomes. The intervention was developed with input from Greek members to fit the campus context, and chapters will implement the activities after baseline data collection. The study is conducted as an interventional, environment-focused approach involving active fraternity and sorority participation with University of Washington as the lead site and NIAAA as a collaborator.
Why it matters
Potential benefit: If successful, participants may have more opportunities for social engagement without alcohol, potentially reducing harm from drinking.
How similar studies have gone: Prior work in environmental and alternative-reward approaches has shown promise in reducing drinking-related harm in campus settings, though specific Greek-affiliated programs are less established.
