Note. Sexually active = reported sex within the past 3 months at this interview; Current drinker = reported any alcohol use in the prior 3 months at this interview; Unhealthy alcohol use = AUDIT-C + or PEth ≥50 in the 3 months prior to the study visit; Alcohol expectancies measured at baseline; Generalized Estimating Equation (GEE) models with independence working correlations, and robust standard errors were used for analyses with multiple imputation of missing data; MRSEs assessed every three months.
