Notes: All predictors other than gender were grand-mean centered. Gender was included as a covariate and was dummy coded, 0 = male, 1 = female. Alcohol consumption and problems models used zero-inflated regression models with a negative binomial log link. Alcohol cravings used ordinary least squares regression. IAT = Implicit Association Test.
