: The updated 11 edition of International Classification of Diseases (ICD-11) is expected to be released by the WHO in 2018. Disorders specifically associated with stress will be included in a separate chapter in ICD-11, and will include a revision of ICD-10 PTSD as well as a new diagnosis of complex posttraumatic stress disorder (CPTSD). The proposed symptom structures of ICD-11 PTSD and CPTSD have been validated in several studies previously, however few studies have used the International Trauma Questionnaire (ITQ), a specific measure for ICD-11 PTSD and CPTSD. Given that ICD-11 PTSD and CPTSD diagnoses are intended to be applicable across different cultures and nations, it is important that the constructs be evaluated across diverse populations and languages. : Study of the psychological impact of trauma is relatively new in Lithuania, coinciding with its independence from the Soviet Union in the 1990s. Studies thus far reveal a population suffering from the effects of long-term and systematic political oppression and violence. The aim of this study was to assess the validity of the symptoms and structure of PTSD and CPTSD in a Lithuanian treatment-seeking sample as measured by the ITQ. : A total of 280 patients from outpatient mental health centres participated in this study. PTSD and CPTSD symptoms were measured with the ITQ. We applied confirmatory factor analysis (CFA) and latent class analysis (LCA) for analysis of data. : Our study supported the ICD-11 factor structure of CPTSD, and a three-class model was supported in LCA analysis with a PTSD class, a CPTSD class, and a low symptom class. Findings support the factorial and discriminant validity of the ICD-11 proposals for PTSD and CPTSD in a unique clinical population.
《国际疾病分类》（ICD）第11版预计将于2018年由世界卫生组织发布。与压力特别相关的疾病将被纳入ICD - 11的一个单独章节，其中将包括对ICD - 10创伤后应激障碍（PTSD）的修订以及复杂创伤后应激障碍（CPTSD）的新诊断。此前已有多项研究验证了ICD - 11 PTSD和CPTSD提议的症状结构，但很少有研究使用国际创伤问卷（ITQ），这是一种针对ICD - 11 PTSD和CPTSD的特定测量工具。鉴于ICD - 11 PTSD和CPTSD诊断旨在适用于不同文化和国家，在不同人群和语言中对这些结构进行评估非常重要。
立陶宛对创伤心理影响的研究相对较新，这与该国在20世纪90年代从苏联独立有关。迄今为止的研究表明，该国人口遭受长期系统性政治压迫和暴力的影响。本研究的目的是通过ITQ评估立陶宛寻求治疗样本中PTSD和CPTSD症状及结构的有效性。
共有280名来自门诊心理健康中心的患者参与了本研究。使用ITQ测量PTSD和CPTSD症状。我们应用验证性因素分析（CFA）和潜在类别分析（LCA）对数据进行分析。
我们的研究支持了ICD - 11中CPTSD的因素结构，并且在LCA分析中支持了一个三类模型，即PTSD类、CPTSD类和低症状类。研究结果支持了ICD - 11中PTSD和CPTSD提议在一个独特临床人群中的因素效度和区分效度。
