Primary outcomePrimary: Daily Drinking Questionnaire - Typical Number of Drinks Per Week — 13.51; 12.23; 10.70; 8.95 drinks — p=0.34
Summary
The proposed study will develop a smartphone/mobile app intervention that incorporates ecological momentary assessment (i.e., two brief surveys per day) and daily intervention messaging (2 messages per day) for three weeks to target high-risk alcohol use among young adult college students. The intervention mainly focuses on alcohol expectancies, alcohol use, and consequences and the daily associations between these and includes personalized intervention messages based on participants' own event-level expectations and experiences. Other psycho-educational alcohol-related content is also provided over the course of three week intervention. This mobile app intervention will be used in a randomized controlled trial (RCT) comparing young adult college students who receive the intervention with those who only receive assessments via the mobile app.
