Mobile Alcohol Use Intervention

"The mobile just-in-time adaptive intervention consists of 1) a digital participant dashboard and 2) tailored messages delivered to the participant's cellphone addressing the individual and ecological contexts of alcohol use.~The web-based intervention dashboard includes: 1) a drink counter for participants to log the number and type of drinks (e.g., beer, wine, mixed drink) they consume in a drinking occasion; 2) a calendar which summarizes the number of days on which a participant has consumed alcohol and the number of drinks consumed over the study period, broken out by drink type; 3) a log where participants can set drinking-related goals and update their progress on those goals; and 4) national and local substance use resources.~Participants will receive messages tailored to their drinking situation and ecological context during high-risk drinking times."
