Evidence is lacking on the mental health issues of internally displaced persons, particularly where displacement is prolonged. The COMRAID study was carried out in year 2011 as a comprehensive evaluation of Muslims in North-Western Sri Lanka who had been displaced since 1990 due to conflict, to investigate the prevalence and correlates of common mental disorders.
A cross-sectional survey was carried out among a randomly selected sample of internally displaced people who had migrated within last 20 years or were born in displacement. The total sample consisted of 450 adults aged 18-65 years selected from 141 settlements. Common mental disorders (CMDs) and post-traumatic stress disorder (PTSD) prevalences were measured using the Patient Health Questionnaire and CIDI sub-scale respectively.
The prevalence of any CMD was 18.8%, and prevalence for subtypes was as follows: somatoform disorder 14.0%, anxiety disorder 1.3%, major depression 5.1%, other depressive syndromes 7.3%. PTSD prevalence was 2.4%. The following factors were significantly associated with CMDs: unemployment (odds ratio 2.8, 95% confidence interval 1.6-4.9), widowed or divorced status (4.9, 2.3-10.1) and food insecurity (1.7, 1.0-2.9).
This is the first study investigating the mental health impact of prolonged forced displacement in post-conflict Sri Lanka. Findings add new insight in to mental health issues faced by internally displaced persons in Sri Lanka and globally, highlighting the need to explore broader mental health issues of vulnerable populations affected by forced displacement.
关于境内流离失所者的心理健康问题，尤其是在流离失所时间较长的情况下，缺乏相关证据。COMRAID 研究于 2011 年开展，对 1990 年以来因冲突而在斯里兰卡西北部被迫背井离乡的穆斯林进行了全面评估，以调查常见精神障碍的流行情况及其相关因素。
在过去 20 年内迁移或出生在流离失所环境中的境内流离失所者中，随机选择样本进行横断面调查。从 141 个定居点中抽取了 450 名年龄在 18-65 岁之间的成年人作为总样本。使用患者健康问卷和 CIDI 子量表分别测量常见精神障碍（CMD）和创伤后应激障碍（PTSD）的患病率。
任何 CMD 的患病率为 18.8%，亚型患病率如下：躯体形式障碍 14.0%，焦虑障碍 1.3%，重度抑郁 5.1%，其他抑郁综合征 7.3%。PTSD 的患病率为 2.4%。以下因素与 CMD 显著相关：失业（优势比 2.8，95%置信区间 1.6-4.9）、丧偶或离异（4.9，2.3-10.1）和粮食不安全（1.7，1.0-2.9）。
这是第一项研究调查了斯里兰卡冲突后长期被迫流离失所对心理健康的影响。研究结果为斯里兰卡和全球境内流离失所者面临的心理健康问题提供了新的见解，强调需要探讨受被迫流离失所影响的弱势群体的更广泛的心理健康问题。
