Data from “Perfectionism, Negative Motives for Drinking, and Alcohol-Related Problems: A 21-day Diary Study”

Two datasets include self-report data from (a) a 21-day daily diary study (N = 263) and (b) a cross-sectional psychometric study (N = 139) of emerging adult drinkers. Data were collected from two Canadian cities, and represent unique, non-overlapping participants in both datasets. Questionnaires assessed perfectionism, reinforcement sensitivity, big five personality traits, alcohol consumption/problems, binge eating, social support, positive and negative affect, social anxiety, and drinking motives. Daily data were originally analysed using multilevel structural equation modelling and are stored in the Open Science Framework (https://osf.io/gduy4/). These data can be used to examine research questions related to personality, emotions, and alcohol consumption, including changes from day-to-day in many variables.
