The aim of this study is to evaluate the validity and the utility of the Japanese version of the WHO-Five Well-Being Index (WHO-5-J) in the context of detecting suicidal ideation in elderly community residents.
A sample of 696 subjects aged 70 years or over who completed a set of questionnaires was examined.
Cronbach's alpha was 0.87 and Loevinger's coefficient was 0.64. The total score was significantly correlated with the number of cohabitants, the number of physical illnesses, physical functioning, instrumental activities of daily living, and depressive symptoms. Subjects with suicidal ideation had significantly lower scores on the WHO-5-J. The receiver-operating characteristic curve analysis indicated that the scale significantly discriminated the subjects with suicidal ideation. When combined with the assessment of a lack of perceived social support (PSS), a standard cut-off criterion of "a total score < or = 12 or answering 0 or 1 to any of the five items" more appropriately identified elderly subjects with suicidal ideation: sensitivity = 87%, specificity = 75%, negative predictive value = 99%, and positive predictive value = 10%.
In combination with PSS, the scale has predictive utility to detect suicidal ideation in elderly community residents.
本研究旨在评估日本版世界卫生组织-五福安康指数（WHO-5-J）在检测老年社区居民自杀意念方面的有效性和实用性。
对696名70岁及以上完成一套问卷的受试者样本进行了检查。
克朗巴哈系数为0.87，洛温杰系数为0.64。总分与同居人数、身体疾病数量、身体功能、日常生活工具性活动及抑郁症状显著相关。有自杀意念的受试者在WHO-5-J上的得分显著更低。受试者工作特征曲线分析表明，该量表能显著区分有自杀意念的受试者。当与感知到的社会支持缺乏（PSS）评估相结合时，“总分≤12或五项中的任何一项回答为0或1”这一标准截断标准能更恰当地识别有自杀意念的老年受试者：灵敏度=87%，特异度=75%，阴性预测值=99%，阳性预测值=10%。
与PSS相结合，该量表在检测老年社区居民自杀意念方面具有预测效用。
