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.
本研究旨在确定在重大平民灾难幸存者人群中，弹性、缓解、慢性和复发性创伤后应激障碍（PTSD）的相对分布。探索残留 PTSD 症状以确定未来复发的预测因素。通过事件影响量表（IES）在灾难后 5.5 个月、14 个月和 5 年进行症状测量。灾难 27 年后对 48 名幸存者（79%）进行了访谈。使用 DSM-IV 轴 I 障碍结构临床访谈（SCID-I）确定 PTSD 状态。分布情况为：58.3%有弹性，14.6%缓解，8.3%慢性，18.8%复发性 PTSD。创伤后 14 个月和 5 年的侵入和回避残留症状数量预测了以后的复发。一般来说，侵入症状，特别是与睡眠相关的侵入症状，是最一致的预测因素，值得特别关注。
