The development of multiple theoretical models and measures of impulsivity has led to inconsistent use of this term and disagreement regarding the most salient predictors of alcohol-related outcomes. The present study examined whether self-report and behavioral measures of impulsivity measure the same construct and how eight conceptually distinct facets of impulsivity relate to alcohol-related outcomes. Participants completed measures and tasks to assess alcohol use, alcohol problems, trait impulsivity, and behavioral impulsivity. The UPPS-P and behavioral measures of impulsivity were largely uncorrelated with each other. Negative urgency and alcohol use emerged as direct predictors of alcohol-related problems. Lack of premeditation demonstrated an indirect effect on alcohol-related problems. Results support previous research suggesting behavioral and self-report measures of impulsivity do not assess the same construct. Further, results suggest that negative urgency may be the most predictive of alcohol-related problems when accounting for self-report and behavioral components of impulsivity.
