We investigate the prevalence and risk factor profiles of Intermittent Explosive Disorder (IED) and comparison between two diagnostic measures for IED in a large population-based study of three ethnic groups of refugees (Chin, Kachin and Rohingya) from Myanmar resettled in Malaysia.
Trained field personnel interviewed in total 2058 refugees, applying a clustered, probabilistic, proportional-to-size sampling framework and using the DSM-IV and DSM-5 criteria to diagnose IED. We used descriptive and bivariate analyses to explore associations of IED (using DSM IV or DMS 5) with ethnic group membership, sociodemographic characteristics and exposure to premigration traumatic events (TEs) and postmigration living difficulties (PMLDs). We also examined associations of IED with other common mental disorders (CMDs) (depression, anxiety and posttraumatic stress disorder) and with domains of functional impairment. Finally, we compared whether IED measured using DSM IV or DSM 5 generated the same or different prevalence.
For the whole sample ( = 2058), the 12-month prevalence of DSM-IV IED was 5.9% ( = 122) and for DSM-5, 3.4% ( = 71). Across the three ethnic groups, 12-month DSM-5 IED prevalence was 2.1% (Chin), 2.9% (Rohingya) and 8.0% (Kachin), whereas DSM-IV defined IED prevalence was 3.2% (Chin), 7% (Rohingya) and 9.2% (Kachin). Being single, and exposure to greater premigration TEs and PMLDs were each associated with IED. Over 80% of persons with IED recorded one or more comorbid CMDs. Persons with IED also showed greater levels of functional impairment compared with those without IED.
The pooled IED prevalence was higher than global norms but there was substantial variation in prevalence across the three study groups.
我们在一项对来自缅甸的三个少数民族（华裔、克钦族和罗兴亚族）难民的大型基于人群的研究中，调查间歇性爆发障碍（IED）的患病率和危险因素特征，并比较两种用于 IED 的诊断方法。
受过培训的现场工作人员共对 2058 名难民进行了访谈，采用聚类、概率、与规模成比例的抽样框架，并使用 DSM-IV 和 DSM-5 标准诊断 IED。我们使用描述性和双变量分析来探索 IED（使用 DSM-IV 或 DSM-5）与族裔群体、社会人口特征以及与移民前创伤事件（TEs）和移民后生活困难（PMLDs）的暴露的关联。我们还检查了 IED 与其他常见精神障碍（CMD）（抑郁、焦虑和创伤后应激障碍）以及功能障碍领域的关联。最后，我们比较了使用 DSM-IV 或 DSM-5 测量的 IED 是否产生相同或不同的患病率。
对于整个样本（n=2058），DSM-IV IED 的 12 个月患病率为 5.9%（n=122），DSM-5 为 3.4%（n=71）。在三个族裔群体中，DSM-5 定义的 12 个月 IED 患病率为 2.1%（华裔）、2.9%（罗兴亚族）和 8.0%（克钦族），而 DSM-IV 定义的 IED 患病率为 3.2%（华裔）、7%（罗兴亚族）和 9.2%（克钦族）。单身以及更多的移民前 TEs 和 PMLDs 的暴露与 IED 有关。超过 80%的 IED 患者记录了一种或多种共患 CMD。与没有 IED 的人相比，患有 IED 的人表现出更大程度的功能障碍。
总的 IED 患病率高于全球标准，但在三个研究组之间存在很大的差异。
