A cluster analysis was used to identify groups of inpatients with confirmed post‐traumatic stress disorder (PTSD) due to combat. In Study 1 the MCMI was administered to 256 subjects, in addition to the MMPI, PTSD measures, and background variables. Three clusters resulted: a Traumatic Personality (8‐2), Schizoid Influence (8‐2‐1), and Antisocial Influence (8‐6). Comparison on the MCMI symptom scales, MMPI, and PTSD scales showed that the Antisocial Influence cluster was “healthier” on all measures. The Schizoid Influence was most psychopathological. In Study 2 the MCMI‐II was administered to 136 new subjects who met the same criteria as in Study 1. Four clusters resulted: Global (1–2–6A‐6B‐8A‐8B), Subclinical (1), Aggressive (6A‐6B‐8A), and Detached/Self‐defeating (1–2‐8A‐8B).
