Brief Summary

The primary aims of this project are to determine the feasibility and acceptability of recruiting and retaining young adult binge drinkers online and using text messaging to provide weekly Goal Support (GS) or weekly GS + Coaching for Context-specific Peer Support (CCPS) on alcohol consumption.
