Personality disorder symptomatology among Vietnam veterans with combat-related PTSD.Anxiety. 1996; 2(6):286-95.A
This research examined self-report personality profiles of 42 Vietnam veterans with combat-related posttraumatic stress disorder (PTSD) evaluated at an outpatient Veteran's Administration hospital PTSD clinic. Assessment was via the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev; DSM-III-R) Personality Disorders-II (SCID-II) self-report. Self-reported personality disorder symptomatology of PTSD patients was contrasted with that of 51 outpatients with a primary diagnosis of an anxiety disorder other than PTSD and with 16 patients with a primary diagnosis of major depressive disorder (MDD). Symptomatology from each of the 11 DSM-III-R categories and from the three personality disorder "clusters" was calculated in terms of percentage of possible traits endorsed, thus creating personality "profiles" for the three groups. PTSD veterans endorsed more traits overall than did both the mixed anxiety and MDD groups, particularly on the Cluster A, avoidant, and borderline scales. Results suggest a PTSD-related personality profile characterized by emotional lability/poor anger control, paranoia/suspiciousness, identity disturbance/confusion, social withdrawal/avoidance, and feelings of emptiness and boredom.
