摘要

社區老人較常見的精神疾病是非重症的精神病，發展針對非重症精神病的簡易篩選量表是及早發現及早治療的先決條件。然而，現今並未有一簡易篩選量表可以應用於社區非重症精神病的老人。本研究的目的，乃檢驗12題版華人健康量表(CHQ-12)在社區老人之適用性。會談者評估222位社區老人於華人健康量表之得分，再依老年精神狀態量表(GMS)及電腦診斷輔助程式(AGECAT)之精神疾病診斷為效標，應用Relative Operating Characteristics (ROC)分析最適當切分點且計算各效度係數，並探討可能影響效度的因素。結果顯示2/3為最適當的切分點，其敏感度為79.7%、特異度為83.6%、陽性預測值為68.9%、陰性預測值為90.0%、錯誤分類率為17.6%。男性、接受過正式教育、及未有身體疾病者有較好的效度。整體而言，針對社區老人之非重症精神疾病，華人健康量表為一好的篩選工具。然而，因為台灣地區有高比例的老人未接受過任何教育，建議使用此量表時以訪員讀題方式為佳。

There has been no validated screening instrument for use in non-psychotic illness of the elderly in Taiwan. This study aims to test the validity of the 12item Chinese Health Questionnaire (CHQ-12) among the elderly in a community study. The CHQ-12 was administrated via reading-out to 222 subjects aged 65 and over from three communities. Psychiatrists using the Geriatric Mental Status Schedule (GMS) assessed psychiatric condition while the diagnosis was made according to the computerized program, AGECAT. Validity indices of the CHQ-12 were calculated, using the Relative Operating Characteristic (ROC) analysis for its optimal cut-off point. Variables hypothesized to affect its performance were assessed. Validity of the CHQ-12 at optimal cut-off point 2/3 were estimated with a sensitivity of 79.7%, a specificity of 83.6%, a positive predictive value of 68.9%, a negative predictive value of 90.0% and an overall misclassification rate of 17.6%, and an estimate of the area under the ROC curve of 0.81. The performance of the CHQ-12 was better in males, in those who were literate, and in those without any physical illness. This study demonstrated that the use of CHQ-12 in the elderly community is as valid as in the general population survey. However, it should be read out by the investigator rather than self-administered due to the high proportion of illiteracy among the Taiwanese elderly.
