Narcissistic vulnerability and the development of PTSD: a prospective study.

This study empirically examined the role of narcissistic traits and narcissistic vulnerability in the development of post-traumatic stress disorder (PTSD). One hundred forty-four survivors of a traumatic event were assessed 1 week, 1 month, and 4 months following the event. In the first-week assessment, patients were administered the Narcissistic Vulnerability Scale and self-reported rating scale to assess event severity and symptoms ensuing from the impact of the traumatic event: depression, intrusions, avoidance, and arousal. In the follow-up assessments, subjects were interviewed on the Clinician-Administered PTSD Scale and were readministered the self-rating symptoms scale. Survivors who developed acute (1 month) and chronic (4 months) PTSD had significantly higher levels of narcissistic vulnerability in the first-week assessment. Narcissistic Vulnerability Scale scores predicted PTSD status with sensitivity of 81.6% and 85.1% and specificity of 40.4% and 38.6% at the 1-month and 4-month assessments, respectively. Narcissistic vulnerabilities contribute to the occurrence of PTSD.
