本研究有两个目的。第一项是评估日本版世界卫生组织(WHO)五种幸福感指数(WHO-5-J)作为简明幸福感量表的信度和效度。第二项是检验这项测试作为糖尿病患者当前抑郁发作筛查工具的区别性有效性。129名糖尿病患者的样本完成了WHO-5-J。根据DSM-IV，其中65人还接受了精神病学家的采访，以评估他们目前是否有任何抑郁发作。内部一致性用Cronbach‘sα、洛文杰同质性系数和因子分析进行评价。通过与可能与主观幸福感相关的外部量表的相关性来评估外部同时效度。采用受试者工作特征(ROC)分析评价判别效度。Cronbach‘sα和Loevinger系数估计分别为0.89和0.65。因素分析只确定了一个因素。WHO-5-J与一些主要的糖尿病并发症、抑郁、焦虑和主观生活质量显著相关。ROC分析显示WHO-5-J可用于检测当前抑郁发作(曲线下面积：0.92；95%可信区间：0.85-0.98)。以~lt；13为临界值，可获得最佳的敏感性/特异性折衷：敏感性，100%；特异性，78%。因此，WHO-5-J被发现具有足够的信度和效度，表明它是检测糖尿病患者当前抑郁发作的有用工具。
The present study had two aims. The first was to evaluate the reliability and the validity of the Japanese version of the World Health Organization (WHO)-Five Well-Being Index (WHO-5-J) as a brief well-being scale. The second was to examine the discriminatory validity of this test as a screening tool for current depressive episodes in diabetic patients. A sample of 129 diabetic patients completed the WHO-5-J. Of these, 65 were also interviewed by psychiatrists to assess whether they had any current depressive episodes according to DSM-IV. The internal consistency was evaluated using Cronbach's alpha, the Loevinger coefficient of homogeneity, and factor analysis. The external concurrent validity was evaluated by correlations with the external scales potentially related to subjective well-being. Discriminatory validity was evaluated using receiver operating characteristic (ROC) analysis. Cronbach's alpha and the Loevinger coefficient were estimated to be 0.89 and 0.65, respectively. A factor analysis identified only one factor. The WHO-5-J was significantly correlated with a number of major diabetic complications, depression, anxiety, and subjective quality of life. ROC analysis showed that the WHO-5-J can be used to detect a current depressive episode (area under curve: 0.92; 95% confidence interval: 0.85-0.98). A cut-off of < 13 yielded the best sensitivity/specificity trade-off: sensitivity, 100%; specificity, 78%. The WHO-5-J was thus found to have a sufficient reliability and validity, indicating that it is a useful instrument for detecting current depressive episodes in diabetic patients.
