PRIMARY outcome
Timeframe: Assessed over prior 30 days at 3 month follow-upThe total number of alcohol-related consequences experienced over the past 30 days is measured by the Brief Young Adult Alcohol Consequences Questionnaire (BYAACQ), which is a checklist of 24 items; scores range from 0-24; higher numbers of items endorsed indicate more problems experienced in the past 30 days

SECONDARY outcome
Timeframe: Assessed over prior 30 days at 3 month follow-upperceived descriptive norms are assessed using a variation on the Drinking Norms Rating Form, which asks respondents to estimate the number of standard drinks consumed by other students on campus for each day in a typical week in the past 30 days; daily estimates are summed to yield perceived number of drinks per week for student peers; range of scores can go from zero to no upper limit

SECONDARY outcome
Timeframe: Assessed over prior 30 days at 3 month follow-upperceived injunctive norms are assessed using the Krieger et al. (2016) adaptation of the Drinking Norms Rating Form, which asks respondents to estimate the how many standard drinks is deemed acceptable by other students on campus to drink on each day in a typical week in the past 30 days; estimates are summed to yield number of drinks per week approved of by student peers; the scores can range from zero to no upper limit
