Abstract

This study identified clinically meaningful psychopathology subgroups of drug-dependent male veterans based on cluster analysis of Millon Clinical Multiaxial Inventory-II (MCMI-II) records completed shortly after inpatient admission. A high pathology cluster subgroup was defined by clinically significant elevations on multiple personality disorder and symptom scales. An antisocial cluster subgroup was identified by a highly significant mean elevation on the Antisocial scale and secondary clinical elevations on the Aggressive and Narcissistic scales. Finally, a subclinical cluster subgroup was defined by the absence of clinically significant elevations on any MCMI- II scales. In comparison with members of the other two groups, members of the high pathology subgroup exhibited more substance abuse and psychiatric problems and less favorable attitudes relevant to HIV-AIDS risk reduction.
