While the factor structure of post-traumatic stress disorder (PTSD) symptoms has been investigated among various traumatized populations in Western and high-income countries, knowledge regarding the validity of factor structure of PTSD among culturally diverse populations in low-and-middle-income countries is limited. The current study examined the factor structure and cultural invariance of PTSD in 521 Iraqi and 993 Syrian war-affected displaced people who were living in the Kurdistan Region of Iraq. Results from confirmatory factor analyses demonstrated that alternative factor models for PTSD, including a new model derived from this population (anhedonia and affect model) resulted in a better fit than the current DSM V models. Taken together, the results showed that a good fit, as well as the measurement invariance of PTSD factors, could be obtained by applying the anhedonia and hybrid model. This study provides further support for the anhedonia and hybrid model of PTSD and fills an important gap in knowledge about the validity of PTSD symptom clusters among Arab and Kurdish populations.
虽然创伤后应激障碍（PTSD）症状的因素结构已在西方和高收入国家的各种受创伤人群中进行了调查，但关于中低收入国家文化多元人群中PTSD因素结构有效性的知识有限。本研究调查了生活在伊拉克库尔德地区的521名伊拉克和993名叙利亚受战争影响的流离失所者中PTSD的因素结构和文化不变性。验证性因素分析结果表明，PTSD的替代因素模型，包括从该人群中得出的新模型（快感缺失和情感模型），比当前的《精神疾病诊断与统计手册》第五版（DSM V）模型拟合得更好。总体而言，结果表明，应用快感缺失和混合模型可以获得良好的拟合以及PTSD因素的测量不变性。本研究为PTSD的快感缺失和混合模型提供了进一步支持，并填补了阿拉伯和库尔德人群中PTSD症状群有效性知识的重要空白。
