本研究在中国地震幸存者流行病学样本中调查了DSM-5 PTSD症状的潜在维度。样本中女性810人，男性386人，平均年龄47.9岁（SD = 10.0，范围16-73岁）。使用DSM-5的PTSD检查表评估PTSD症状，并使用验证性因子分析评估替代模型。结果表明，由入侵、回避、负面情绪、快感缺乏、烦躁唤醒和焦虑唤醒因素组成的六因素模型是最适合的模型。目前的研究结果补充了最近发布的DSM-5中关于创伤后应激障碍症状潜在结构的有限文献，并对进一步的创伤相关研究和临床实践具有启示意义。(c) 2014 Elsevier Ltd.版权所有。
The current study investigated the underlying dimensions of DSM-5 PTSD symptoms in an epidemiological sample of Chinese earthquake survivors. The sample consisted of 810 females and 386 males, with a mean age of 47.9 years (SD = 10.0, range: 16-73). PTSD symptoms were assessed using the PTSD Checklist for DSM-5, and alternative models were evaluated with confirmatory factor analysis. Results indicated that a six-factor model comprised of intrusion, avoidance, negative affect, anhedonia, dysphoric arousal, and anxious arousal factors emerged as the best fitting model. The current findings add to limited literature on the latent structure of PTSD symptoms described in the recently released DSM-5, and carry implications for further trauma-related research and clinical practice.
