Within-person effects of daily reminders on alcohol consumption
We tested the feasibility of psychological distancing reminders to reduce the number of drinking occasions and drinks per occasion on active, intervention weeks versus inactive, non-intervention weeks. To assess differences in drinking on active versus inactive weeks, we specified two separate multilevel hurdle models, one for Study 1 and another for Study 2. The main predictor was active week (vs. inactive week). Consistent with prior workPsychological distance reminders reduce drinking frequency but do not influence amount. a. Collapsing across experimental conditions, participants in the mindfulness and perspective-taking groups were less likely to drink following active intervention reminders relative to following control reminders in Study 1 (left) and Study 2 (right). b. We found no differences in the number of drinks consumed on alcohol use occasions following active intervention reminders, relative to following control reminders across both studies, Study 1 (left) and Study 2 (right).
