The current project uses a web-based program called the Expectancy Challenge Alcohol Literacy Curriculum (ECALC) to reduce alcohol use and associated harms among college students. Participants complete the interactive program in 50 minutes, and then provide daily, real-time data on expectancies and alcohol use for 3 weeks after intervention, and again for one week at 13 and 25 weeks after intervention. One group will also receive biweekly boosters delivered via smart phone to assess their impact on intervention decay over time. It is hypothesized that ECALC effects may decay over time, and that biweekly boosters will prevent this decay. Access to the ECALC is available on request from the principal investigator.
