Concurrent Validation of the Millon Clinical Multiaxial Inventory among Vietnam Veterans with Posttraumatic Stress Disorder

Abstract

A carefully derived group of 60 Posttraumatic Stress Disorder (PTSD) inpatient Vietnam veterans was identified and given two psychometric inventories, the Millon Clinical Multiaxial Inventory and the Sixteen Personality Factor Test to identify a profile for this disorder among Vietnam veterans. A profile of the Passive-Aggressive and Avoidant personality patterns (8–2) resulted. The personality patterns of Schizoid and Borderline were present as influencing styles, as were the symptom disorders of Dysthymia and Anxiety. The 16 PF pattern of this group was low on Warmth, Emotional Stability, Happy-Go-Lucky, Boldness, Self-discipline, and Extraversion, and high on Suspiciousness, Insecurity, Self-sufficiency, and Anxiety. Also, using the method developed by Krug for the 16 PF, a 1322 (or 2322) style resulted. This style is noted for its anxiety and introversion components. Both scales are useful in identification and description of PTSD.
