Note. Pre = prior to randomization, 1-week FU = 1-week follow-up, 3-month FU = 3-month follow-up.
While we will administer the full AUDIT at baseline (pre-treatment) and at the 3-month follow-up assessment, only the first three items of the AUDIT will be included in treatment outcome analyses given potential floor effects for items 4-10.
Demographic characteristics will be added to models as covariates if they are significantly different across randomization groups.
