创伤后应激障碍(PTSD)在DSM-IV中被定义为一种焦虑障碍，包括重复体验、回避和过度唤醒的症状群。一些研究已经检验了创伤后应激障碍症状的因素结构。据我们所知，还没有研究在完全由失去亲人的个人组成的样本中检查与损失相关的创伤后应激障碍症状的因素结构。这样的检查很重要，因为它可以促进我们对面临不同厌恶生活事件的群体的创伤后应激障碍症状结构的稳定性以及丧失后创伤后应激障碍症状发生的潜在过程的理解。在这项研究中，对347名哀悼者的创伤后应激障碍症状的因素结构的五种可选模型进行了检验。结果表明，在这组人中，创伤后应激障碍症状最好被概念化为形成四个因素：重复体验、回避、烦躁不安和高度唤醒。与抑郁和复杂悲痛相关的模式支持了该模型的有效性。(C)2008爱思唯尔有限公司。保留所有权利。
Posttraumatic Stress Disorder (PTSD) is defined in DSM-IV as an anxiety disorder that encompasses symptom-clusters of reexperiencing, avoidance, and hyperarousal. Several studies have examined the factor structure of PTSD symptoms. To our knowledge, no studies have yet examined the factor structure of loss-related PTSD symptoms in samples exclusively comprised of bereaved individuals. Such an examination is important because it can advance our understanding of the stability of the structure of PTSD symptoms across groups confronted with different aversive life-events and of processes underlying the occurrence of PTSD symptoms after loss. In this study, five alternative models of the factor structure of PTSD symptoms were examined in a sample of 347 mourners. Results showed that, in this group, PTSD symptoms are best conceptualized as forming four factors: reexperiencing, avoidance, dysphoria, and hyperarousal. Patterns of correlations with depression and complicated grief supported the validity of the model. (c) 2008 Elsevier Ltd. All rights reserved.
