Personality Traits and Drinking Motives Predict Alcohol Misuse Among Canadian Aboriginal Youth

This study tested the association between personality traits (i.e., anxiety sensitivity, sensation seeking, impulsivity, and hopelessness; as measured by the Substance Use Risk Profile Scale (Woicik et al. in Addictive Behaviors 34:1042-1055, 2009)), drinking motives (i.e., enhancement, social, coping, and conformity; as measured by the Drinking Motives Questionnaire-Revised (Cooper in Psychological Assessment 6:117-128, 1994)), and problematic patterns of alcohol use in 191 Canadian Aboriginal youth. Confirmatory factor analyses provided support for a three-factor model of drinking motives. Hierarchical regression analyses demonstrated that personality traits independently predicted motives for alcohol use: anxiety sensitivity predicted conformity motivated drinking; sensation seeking and impulsivity predicted enhancement motivated drinking; and hopelessness predicted coping motivated drinking. In addition, personality traits and drinking motives predicted problematic patterns of alcohol misuse: sensation seeking, hopelessness, and enhancement motives predicted heavy episodic drinking, while all personality traits and all drinking motives (save conformity) predicted alcohol-related problems. These findings suggest that specific personality traits in Canadian Aboriginal youth can explain specific reasons for drinking and may represent appropriate targets for intervention.
