Mediation model 1: indirect effect of environmental reward on alcohol use sequentially through severity of depressive symptoms and coping motives. PHQ, Patient Health Questionnaire; DMQ-R, Drinking Motives Questionnaire—Revised. Mediation model 2: indirect effect of COVID-related distress on alcohol use through coping motives. Confidence intervals presented here are 95% bias-corrected bootstrap estimates.
