目的方法本研究旨在完成国际创伤问卷（ITQ）的编制，ITQ是国际疾病分类（ICD-11）第11版中定义的创伤后应激障碍（PTSD）和复杂性PTSD（CPTSD）的自我报告诊断工具。PTSD和CPTSD的最佳症状指标进行了确定，通过应用项目反应理论（IRT）分析的数据从创伤暴露的社区样本（n = 1051）和创伤暴露的临床样本（n = 247）从英国。优化的12个项目的ITQ的效度进行了验证性因素分析。诊断率进行了估计，并与以前的验证研究。结果结论附录12项优化ITQ的潜在结构与先前的研究结果一致，PTSD和CPTSD的诊断率与先前的估计一致。ITQ是PTSD和CPTSD核心特征的简短、简单的衡量标准。它符合ICD-11的组织原则，即通过关注有限但重要的一组症状来最大限度地提高临床实用性和国际适用性。该措施可免费获得，并可在本文正文中找到。
Objective Method The purpose of this study was to finalize the development of the International Trauma Questionnaire (ITQ), a self-report diagnostic measure of post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD), as defined in the 11th version of the International Classification of Diseases (ICD-11). The optimal symptom indicators of PTSD and CPTSD were identified by applying item response theory (IRT) analysis to data from a trauma-exposed community sample (n = 1051) and a trauma-exposed clinical sample (n = 247) from the United Kingdom. The validity of the optimized 12-item ITQ was assessed with confirmatory factor analyses. Diagnostic rates were estimated and compared to previous validation studies. Results Conclusion Appendix The latent structure of the 12-item, optimized ITQ was consistent with prior findings, and diagnostic rates of PTSD and CPTSD were in line with previous estimates. The ITQ is a brief, simply worded measure of the core features of PTSD and CPTSD. It is consistent with the organizing principles of the ICD-11 to maximize clinical utility and international applicability through a focus on a limited but central set of symptoms. The measure is freely available and can be found in the body of this paper.
