世界卫生组织五项身心健康指标在识别高中生抑郁障碍中的信效度(1)
【摘 要】 目的:考查世界卫生组织五项身心健康指标(World Health Organization Five-item Well-Being Index ,WHO-5)在识别高中生抑郁障碍中的信度和效度。方法:用WHO-5对上海市1所中学706名高一到高三年级学生进行初测，计算WHO-5的 Cronbach α系数，进行因子分析判定其结构效度；初测同时使用Beck抑郁量表(Beck Depression Inventory,BDI)测试，计算WHO-5与BDI平行效度；2周后对104名学生用WHO-5进行重测，计算重测信度；对BDI总分≥14分的学生和10% 的BDI总分<14分的学生共134人用简明国际神经精神访谈(Mini International Neuropsychiatry Inventory，MINI)进行访谈，根据WHO-5总分以MINI诊断抑郁障碍为金标准绘制ROC曲线，判定其校标效度，确定曲线下面积、临界值及相对应的敏感度和特异度。结果:Cronbach α系数为0.907；重测信度系数ICC=0.644；因子分析表明WHO-5为单因子结构；WHO-5与BDI得分呈负相关(r=-0.52)； ROC曲线下面积为0.714，临界值取11.5或12.5时有较平衡的敏感度/特异度，分别为70%/62%或85%/56%。结论:世界卫生组织五项身心健康指标具有较好的内在一致性，但敏感度尚可而特异度一般。其对高中生抑郁障碍的识别有一定适用性，但只能作为一种粗筛工具。

【Abstract】 Objective:To examine the reliability and validity of the World Health Organization Five-item Well-Being Index (WHO-5) for detecting depressive disorders in senior middle school students.Methods:A sample of 706 grade 1 to grade 3 students from one senior middle school in Shanghai completed the WHO-5.Cronbach' s alpha coeffiicient and structure validity were examined.Structure validity was evaluated using factor analysis.The Beck Depression Inventory (BDI) was used to explore the correlative validity.Totally 104 students were readministered the WHO-5 2 weeks after its initial administration to assess the test-retest reliability.And 134 students were also interviewed by psychiatrists to assess whether they had any depressive disorders according to Mini International Neuropsychiatry Inventory (MINI).MINI was regarded as the gold standard to investigate the validity of WHO-5.Criterion-related validity was evaluated using receiver operating characteristic ROC analysis.Results:The Cronbach' s alpha was estimated to be 0.907.the test-retest reliability was 0.644.A factor analysis identified only one factor.The WHO-5 was significantly correlated with BDI.Correlative validity was -0.52.ROC analysis showed that the WHO-5 could be used to detect depressive disorders (area under curve:0.714).A cut-off of 11.5 or 12.5 yielded the balanced sensitivity/specificity trade-off:70%/62% or 85%/56%.Conclusion:The World Health Organization Five-item Well-Being Index (WHO-5) has an adequate internal consistency.The WHO-5 demonstrates good sensitivity and common specificity.It may be a coarse-screen instrument for detecting depressive disorders in senior middle school students.
