Personality subgroups in an inpatient Vietnam veteran treatment program.

Millon Clinical Multiaxial Inventory personality profiles of 250 male inpatient Vietnam veterans were examined to locate subgroups within that population. Using a hierarchical cluster analysis to form relatively homogeneous groups, four clusters were identified which accounted for 98% of the population. Three clusters had Millon profiles suggestive of a stress reaction and one cluster had a profile indicative of an antisocial adjustment.

Treatment outcomes of Vietnam veterans with Posttraumatic Stress Disorder.

This study examined changes on the Millon Clinical Multiaxial Inventory for 45 Vietnam veterans who completed a specialized inpatient treatment program. The average length of stay for these veterans was 140 days. Patients' scores on the Millon decreased on 12 of the 20 scales and increased on 8, and their Posttraumatic Stress Disorder-related symptoms of anxiety and dysthymia decreased significantly.

Adapted character styles of Vietnam veterans with Posttraumatic Stress Disorder.

A total of 189 male Vietnam veterans who were admitted to a specialized inpatient treatment program were evaluated using the Millon Clinical Multiphasic Personality Inventory to assess character styles. The veterans were assessed for Posttraumatic Stress Disorder by using a subscale of the Minnesota Multiphasic Personality Inventory (MMPI) and 72% of the patients were classified as having Posttraumatic Stress Disorder. The character styles of passive-aggressive, schizoid, avoidant, and borderline were significantly associated with these patients.
