Two hundred fifty male, alcoholic VA inpatients were administered the Millon Clinical Multiaxial Inventory (MCMI) and the Alcohol Use Inventory (AUI). A cluster analysis, based on the scales of the MCMI, yielded three clusters: Cluster 1 was the smallest and was described by the least overall psychopathology. Cluster 2 had significant elevations on Antisocial, Narcissistic, Paranoid, Drug and Alcohol Abuse scales. Cluster 3 was the largest and had significant elevations on Avoidant, Schizoid, Dependent, Passive-Aggressive, Anxiety, Dysthymia, and Alcohol Abuse scales.
