This project is designed to compare college drinking interventions on outcomes and cost-effectiveness. We plan to recruit 700 students with residence hall alcohol violations to participate in a randomized study to evaluate 3 brief interventions: in-person brief motivational intervention, Alcohol 101plus (an interactive CD-ROM program), and AlcoholEdu (a Web-based tutorial). Participants will be followed over 12 months to determine changes in alcohol consumption and related problems. We will also explore which participants might respond better to one intervention vs the others.
