As part of the prevention programs, alcohol use behaviors were assessed via self-report at the time of the first and final video modules (“Week 1” and “Week 4”), and in a follow-up questionnaire 30 days after completing the programs (“Week 8”). These assessments measured four past-month alcohol use behaviors: number of days drinking alcohol, usual number of drinks per drinking occasion, maximum number of drinks in 24 hours, and number of days drinking four or more alcoholic drinks. The time frame for these behaviors was 30 days prior to assessment, such that Week 1 measures reflected alcohol use in the month prior to the prevention programs, Week 4 measures reflected alcohol use during the month-long programs, and Week 8 measures reflected behaviors in the month after completing the programs.
