目的：国际疾病分类(ICD-11)第11版提出了创伤后应激障碍(PTSD)和复杂性创伤应激障碍(CPTSD)两种相关的创伤诊断方法。使用新开发的创伤后应激障碍和慢性创伤后应激障碍的障碍特异性测量工具国际创伤问卷(ITQ)，本研究将(I)评估ICD-11创伤后应激障碍(PTSD)和持续创伤后应激障碍(CPTSD)的因素效度；(Ii)首次对这些结构的区分效度进行检验；(Iii)首次比较ICD-11和诊断与统计手册(DSM-5)第五版的创伤后应激障碍的诊断率。结果：ICD-11的诊断率显著低于DSM-5。反映创伤后应激障碍和应对方式障碍的双因素二阶模型最好地反映了ITQ的数据；创伤后应激障碍和应对方式障碍因素对多个心理变量具有差异性预测作用。结论：ICD-11的因素效度和判别效度得到支持，ICD-11的诊断病例数低于DSM-5。
Objective: The 11th version of the International Classification of Diseases (ICD-11) has proposed two related trauma diagnoses: Posttraumatic stress disorder (PTSD) and Complex PTSD (CPTSD). Using a newly developed, disorder-specific measure of PTSD and CPTSD called the International Trauma Questionnaire (ITQ) the current study will (i) assess the factorial validity of ICD-11 PTSD and CPTSD; (ii) provide the first test of the discriminant validity of these constructs; and (iii) provide the first comparison of ICD-11, and Diagnostic and Statistical Manual, Fifth Edition (DSM-5), PTSD diagnostic rates using disorder-specific measures.Method: ICD-11 and DSM-5 PTSD-specific measures were completed by a British clinical sample of trauma-exposed patients (N = 171). The structure and validity of ICD-11 PTSD and CPTSD were assessed by means of factor analysis and assessing relationships with criterion variables.Results: Diagnostic rates under ICD-11 were significantly lower than those under DSM-5. A two-factor second-order model reflecting the distinction between PTSD and CPTSD best represented the data from the ITQ; and the PTSD and CPTSD factors differentially predicted multiple psychological variables.Conclusion: The factorial and discriminant validity of ICD-11 PTSD and CPTSD was supported, and ICD-11 produces fewer diagnostic cases than DSM-5.
