Refugees are known to have high rates of post-traumatic stress disorder (PTSD). Although recent years have seen an increase in the number of refugees from Arabic speaking countries in the Middle East, no study so far has validated the construct of PTSD in an Arabic speaking sample of refugees.
Responses to the Harvard Trauma Questionnaire (HTQ) were obtained from 409 Arabic-speaking refugees diagnosed with PTSD and undergoing treatment in Denmark. Confirmatory factor analysis was used to test and compare five alternative models.
All four- and five-factor models provided sufficient fit indices. However, a combination of excessively small clusters, and a case of mistranslation in the official Arabic translation of the HTQ, rendered results two of the models inadmissible. A post hoc analysis revealed that a simpler factor structure is supported, once local dependence is addressed.
Overall, the construct of PTSD is supported in this sample of Arabic-speaking refugees. Apart from pursuing maximum fit, future studies may wish to test simpler, potentially more stable models, which allow a more informative analysis of individual items.
众所周知，难民中创伤后应激障碍（PTSD）的发病率很高。尽管近年来中东地区说阿拉伯语国家的难民数量有所增加，但迄今为止尚无研究在说阿拉伯语的难民样本中验证PTSD的结构。
从丹麦409名被诊断患有PTSD并正在接受治疗的说阿拉伯语的难民那里获得了对哈佛创伤问卷（HTQ）的回答。验证性因素分析用于测试和比较五种替代模型。
所有四因素和五因素模型都提供了足够的拟合指数。然而，由于集群过小以及HTQ官方阿拉伯语翻译中的一处误译，导致其中两个模型的结果不可接受。事后分析表明，一旦解决了局部依赖性问题，就支持更简单的因素结构。
总体而言，该说阿拉伯语的难民样本支持PTSD的结构。除了追求最大拟合度之外，未来的研究可能希望测试更简单、可能更稳定的模型，以便对单个项目进行更有信息量的分析。
