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. The secondary aims will determine effect sizes for GS and GS+CCPS groups relative to controls on alcohol consumption at 6- and 12-weeks to inform design of an adequately-powered trial.

Each week for 6-weeks, control group participants will receive the following weekly text message assessments (without receiving any feedback or support): (1) Thursdays (3pm): weekend plans to drink and desire to get drunk; (2) Sundays (12pm): most drinks consumed on any weekend day and peer pressure to drink.
Each week for 6-weeks, GS group participants will receive prompts and tailored feedback and support focused on weekly drinking limit goal commitment \& confidence assessments and subsequently receive tailored feedback on goal success to either bolster future goal striving or reframe goal failure.
Each week for 6-weeks, CCPS group participants will receive weekly motivation and strategies to enlist peer support during drinking episodes.
