背景：在低收入和中等收入国家验证常见精神障碍（CMD）筛查措施的尝试并不多。本研究的目的是在印度果阿的一项社区研究中检验一般健康问卷12 （GHQ-12）的标准效度。方法：通过对印度果阿地区男性社区队列的二次分析，对照Mini国际神经精神病学访谈（Mini）和世界卫生组织残疾评估量表（WHODAS）对GHQ-12的CMD和功能状态进行同步效度和收敛效度评估。以MINI病例标准为金标准，采用ROC分析确定GHQ-12的效度。同时效度根据WHODAS功能残疾和残疾天数的金标准进行评估。结果：在男性样本（n = 773）中，GHQ-12具有较高的内部信度（Cronbach's alpha为0.82）和可接受的标准效度（受试者工作特征曲线下面积为0.71）。该方法具有足够的心理测量学特性，灵敏度为68.75%，特异度为73.14%，识别CMD的最佳临界值为2分。结论：为了优化GHQ-12的有用性和有效性，在印度果阿邦设置较低的CMD分界点可能是有益的。应该对GHQ-12进行进一步的验证研究，以继续验证该测试在社区中的使用。(C) 2017年作者。这是一篇基于CC by许可的开放获取文章。
Background: There have not been many attempts to validate screening measures for common mental disorders (CMD) in low-and middle-income countries. The aim of this study was to examine the criterion validity of the General Health Questionnaire 12 (GHQ-12) in a community-based study from Goa, India.Method: Concurrent and convergent validity of the GHQ-12 were assessed against the Mini International Neuropsychiatric Interview (MINI) and World Health Organization Disability Assessment Scale (WHODAS) for CMD and functional status through the secondary analysis of a community cohort of men from Goa, India. Criterion validity of the GHQ-12 was determined using ROC analyses with the MINI case criterion as the gold standard. Concurrent validity was assessed against the gold standard of WHODAS functional disability and number of disability days.Results: In a sample of men (n = 773), the GHQ-12 showed high internal reliability (Cronbach's alpha of 0.82) and acceptable criterion validity (Area under the receiver operating characteristic curve being 0.71). It had adequate psychometric properties for the detection of CMD (sensitivity of 68.75%; specificity of 73.14%) with the optimal cut-off score for identification of CMD being 2.Conclusion: In order to optimize the usefulness and validity of the GHQ-12, a low cut-off point for CMD may be beneficial in Goa, India. Further validation studies for the GHQ-12 should be conducted for continued validation of the test for use in the community. (C) 2017 The Authors. Published by Elsevier B.V.
