Note. IAT scores and explicit predictors were grand-mean centered. Gender was dummy-coded (0 = men, 1 = women). Cohen’s d = 2t/√df. The regression models used generalized linear models with a negative binomial log link. Consumption = number of drinks consumed on a typical week in the last three months. ASCS = Alcohol Self-Concept Scale. DMQ-Enhance = the enhance subscale of the Drinking Motives Questionnaire; DMQ-Cope = the coping subscale of the Drinking Motives Questionnaire; BAS-Fun = the fun-seeking subscale of the Behavioral Activation Scale. Corrected alpha = .029.
