Abstract

Research shows high comorbidity between Cluster B Personality Disorders (PDs) and Alcohol Use Disorders (AUDs). Studies of personality traits and alcohol use have identified coping and enhancement drinking motives as mediators of the relation among impulsivity, negative affec-tivity or affectivity instability, and alcohol use. To the extent that certain PDs reflect extreme expression of these traits, drinking motives were hypothesized to mediate the relation between PD symptoms and presence/absence of an alcohol use disorder (AUD). This hypothesis was tested using a series of cross-sectional and prospective path models estimating the extent that coping and enhancement drinking motives mediated the relation between cluster A, B, and C PD symptom counts and AUD diagnosis among a sample of 168 young adults between ages 18 and 21. Enhancement motives mediated the cross-sectional relation between Cluster B symptoms and AUD. Prospectively, enhancement motives partially mediated the relation between Cluster B personality symptoms and AUD through the stability of Year 1 AUD to Year 3 AUD. Results suggest that enhancement motives may be especially important in understanding the relation between Cluster B personality disorders and AUDs.
