Abstract:
The authors factor analyzed DSM-III-based post-traumatic stress disorder symptom ratings made on 131 Vietnam-veteran PTSD patients. Five factors--termed Intrusive Thoughts and Their Effects, Increased Arousal, Impoverished Relationships, Guilt, and Cognitive Interference--emerged. The factor structure gave more support to Laufer, Brett and Gallops' conceptualization of PTSD than to the Horowitz, DSM-III, or DSM-III-R systems. It also generated suggestions for future editions of the diagnostic manual.
