INTRODUCTION The most recent diagnostic criteria of DSM-5 (2013) and ICD-11 (2018) list PTSD encompasses 20 and 6 symptoms, respectively, organized in different structures. The study aimed to investigate the dimensions of the Posttraumatic Stress Disorder Checklist 5 according to the DSM-5's broader definition of PTSD and the ICD-11's narrower approach, as well as to explore an alternative restricted model that retains the core symptoms explicitly related to traumatic experiences. METHODS Data were gathered from [edited out for blind review] employees (N = 1,101) who directly experienced life traumatic events or were exposed to them because of their work activities. Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used to evaluate the configural and metric structures of the models. RESULTS We estimated seven models of the latent structure of PTSD including the four-factor DSM-5 and three-factors ICD-11 PTSD models. Given the lack of validity evidence for them, an alternative 10-symptom model was tested. The final 7-item PTSD model considerably improved estimation of the PTSD construct. This solution showed reliable items with non-redundant content, acceptable fit indices and satisfactory configural and metric properties. CONCLUSION The more parsimonious one-dimensional model comprising the PTSD core symptoms has the potential do improve the assessment of PTSD.

两全其美：将 DSM-5 和 ICD-11 的 PTSD 症状群结合在一个筛查量表中。

引言 DSM-5 (2013) 和 ICD-11 (2018) 的最新诊断标准列出了 PTSD 分别包含 20 种和 6 种以不同结构组织的症状。该研究旨在根据 DSM-5 对 PTSD 的更广泛定义和 ICD-11 的狭义方法来调查创伤后应激障碍检查表 5 的维度，并探索保留与创伤明确相关的核心症状的替代限制模型。经验。方法 数据收集自直接经历过生活创伤事件或因工作活动而接触过这些事件的员工 (N = 1,101)。验证性因素分析（CFA）和探索性结构方程模型（ESEM）用于评估模型的配置和度量结构。结果我们估计了 PTSD 潜在结构的七种模型，包括四因素 DSM-5 和三因素 ICD-11 PTSD 模型。鉴于缺乏有效性证据，我们测试了另一种 10 症状模型。最终的 7 项 PTSD 模型大大改进了对 PTSD 构造的估计。该解决方案显示了具有非冗余内容、可接受的拟合指数以及令人满意的配置和公制属性的可靠项目。结论 包含 PTSD 核心症状的更简洁的一维模型有可能改善 PTSD 的评估。
