本研究评估了瑞典版创伤后应激障碍（PTSD）的自我报告措施的属性，重点是事件量表修订版（IES-R）的影响。2004年印度洋海啸后1年、3年和6年的成年幸存者调查数据（n = 1506）包括IES-R（IES-6的来源）和12项一般健康问卷（GHQ-12）。PTSD检查表（PCL）被纳入一项调查。6年后进行了结构化临床访谈（n = 142）。IES-R和PCL的因素分析表明，一个焦虑-觉醒模型提供了良好的适合不变的评估。这两种措施都准确地排除创伤后应激障碍，而所有措施提供了较差的阳性预测值。IES-R，而不是IES-6和GHQ-12，证明了各项评估的稳定性。总之，瑞典IES-R和PCL是慢性创伤后应激障碍的合理措施，研究结果说明了创伤后应激障碍评估的重要时间方面。(c)2014爱思唯尔有限公司版权所有。
This study evaluated the properties of Swedish versions of self-report measures of posttraumatic stress disorder (PTSD), with emphasis on the Impact of Event Scale-Revised (IES-R). Survey data from adult survivors 1, 3, and 6 years after the 2004 Indian Ocean tsunami (n = 1506) included the IES-R (from which the IES-6 was derived) and the 12-item General Health Questionnaire (GHQ-12). The PTSD Checklist (PCL) was included in one survey. A structured clinical interview was performed after 6 years (n = 142). Factor analyses of the IES-R and PCL indicated that a dysphoric-arousal model provided good fit invariant across assessments. Both measures were accurate in excluding PTSD while all measures provided poorer positive predictive values. The IES-R, but not the IES-6 and GHQ-12, evidenced stability across assessments. In conclusion, the Swedish IES-R and PCL are sound measures of chronic PTSD, and the findings illustrate important temporal aspects of PTSD assessment. (c) 2014 Elsevier Ltd. All rights reserved.
