In another study, Simons (2003) examined predictors of alcohol use-related problems in undergraduates over a 30-day interval. Baseline scores on the Eysenck Impulsiveness Scale (EIS; Eysenck & Eysenck, 1977), affective vulnerability, social norms, and perceived conflict between personal strivings and alcohol use predicted alcohol use-related problems at the second assessment. Structural equation models indicated that impulsivity and affective vulnerability were directly related to use-related problems. Impulsivity moderated the association between alcohol use and alcohol use-related problems; that is, use frequency was associated more strongly with use-related problems among more impulsive participants (Simons, 2003). Taken together, these studies indicate the importance of considering emotional processes in the relationship between impulsivity and alcohol.
