PAI profiles in alcohol-dependent patients.

This study examined the use of a recently developed inventory, the Personality Assessment Inventory (PAI; Morey, 1991), in developing a typology of alcoholic types. Clustering procedures were applied to the PAI clinical scale profiles of a group (N = 301) of alcohol-dependent patients. Seven cluster profiles were identified: Depressed, Antisocial Acts, Personality Disorder, Dysphoric, Somatic Concerns, Normal, and Distressed. Examination of nonclinical PAI scales and several external variables revealed support for the validity of the seven profile types. Results were compared to cluster analysis findings from other inventories with this population.
