摘要
目的:本研究考察我国艾滋病感染者中创伤后应激障碍的发病率及其症状结构。方法:样本1为云南省HIV感染者91名,样本2为该省和北京HIV感染者366名,施测自编创伤事件问卷及创伤后应激障碍检查表(PCLC),用DSM-Ⅳ轴Ⅰ障碍定式临床检查病人版(SCID-I)访谈对样本1被试进行诊断评估,确定PCL-C区分PTSD的分界点;用验证性因素分析比较PTSD症状结构的3个竞争模型。结果:1再体验-回避-麻木-警觉一阶四因子模型拟合最优;2PCL-C区分HIV感染者罹患PTSD的最佳分界点为44分,对应敏感度0.842,特异度0.906,诊断效能0.94,样本1中PTSD发病率为41.80%。结论:PTSD在HIV感染者人群中发病率高,PCL-C在该人群中呈一阶四因子一阶相关结构,提示该种症状分类具有跨样本一致性。
Objective：This research aimed to explore the prevalence of Post-traumatic Stress Disorder（PTSD） and its symptoms classification among Chinese HIV-positive patients.Methods：Ninety-one（sample 1） and 366 HIV-positive patients（sample 2） completed the Traumatic Events Questionnaire and PTSD Checklist-Civilian Version（PCL-C）.The Structured Clinical Interview for DSM-IV AXIS I Disorders（SCID-I） was conducted in sample 1.In sample 2,confirmatory factor analysis was performed to test three competitive models.Results：①The optimal cut-off point of PCL-C for PTSD in HIV sample was 44,with the sensitivity of 0.842,the specificity of 0.906 and the diagnostic efficiency of 0.94.The prevalence of PTSD was 41.80%.②The inter-correlated four-factor model was the best fit for the data.Conclusion：The prevalence of PTSD in HIV-positive people was rather high and the PTSD symptoms classification was best described by the four-factor model,indicating a fairly good cross-sample validation of this model.
