Outcomes
alcohol-related adverse
The primary outcome measure was the self-reported number of binge drinking episodes (defined as >3 standard drinks per occasion for women and individuals aged >65 years and >4 standard drinks per occasion for men) over the previous 28 days, assessed using 28-day TLFB at 12 months after randomization. We hypothesized that at 12 months, AB-CASI would be superior to standard care in reducing the number of binge drinking episodes and the mean number of weekly standard drinks over the last 28 days. Secondary outcomes included the self-reported mean number of weekly standard drinks measured by 28-day TLFB at 12 months after randomization and alcohol-related adverse health behaviors and consequences over the 12-month period. We hypothesized that at 12 months, AB-CASI would be superior to standard care in reducing alcohol-related adverse health behaviors and consequences.
