Abstract

The aim of this study was to establish the relative distribution of resilient, remitted, chronic and reactivated posttraumatic stress disorder (PTSD) in a population of survivors from a major civilian disaster. Residual PTSD symptoms were explored to identify predictors of future reactivation. Symptoms were measured by the Impact of Event Scale (IES) 5.5 months, 14 months and 5 years after the disaster. Forty-eight survivors (79%) were interviewed after 27 years. PTSD status was determined by using the Structural Clinical Interview for DSM-IV axis I Disorders (SCID-I). The distributions were: 58.3% resilient, 14.6% remitted, 8.3% chronic, and 18.8% reactivated PTSD. Number of residual symptoms from intrusion and avoidance 14 months and 5 years past trauma predicted later reactivation. Intrusion symptoms in general, and sleep related intrusions in particular, were the most consistent predictors deserving special attention.
