Craving for either alcohol or grape juice on the ACQ was analyzed in a Mood Condition (3 levels; positive, negative, and neutral) × Craving Type (2 levels; alcohol vs. grape juice) linear mixed-effects model, with urgency as a covariate. This showed a significant main effect of craving type (p < 0.001), and an interaction between mood and craving type (p = 0.028) (See Figure 2), such that the difference in craving between alcohol and grape juice was accentuated in the negative and positive mood conditions. Overall, participants reported higher cravings to alcohol than to grape juice across conditions (mean alcohol craving = 2.30 vs. mean grape juice craving = 1.71 on a scale of 1-7). Alcohol and grape cravings were, however, weakly correlated (r = 0.21, p = 0.05).
