Note. N = 87. All predictors were centered prior to analysis. Holm-modified Bonferroni p values used to indicate statistical significance at the omnibus level. Confidence intervals and standard errors were calculated using bias-corrected and accelerated confidence intervals with 1,000 replicates. BW = behavioral willingness; DMQ-R = Drinking Motives Questionnaire–Revised; social = DMQ-R social motives; coping = DMQ-R coping motives; enhancement or Enh = DMQ-R enhancement motives. Bold values indicate p < .05.
