This study evaluated the effectiveness of a web-based personalized normative feedback program, electronic Check-Up to Go (e-CHUG), in decreasing heavy drinking among 1st-year university students. Results indicated high-risk students receiving the e-CHUG program during 1st-year orientation activities reported significantly greater reductions in heavy drinking and alcohol-related consequences than did students in an assessment-only control group at a 3-month follow-up. Recommendations for integrating e-CHUG into orientation activities are discussed. (Contains 1 figure and 1 table.)
