A study of the validity of the 30- and 12-item versions of the Chinese Health Questionnaire (CHQ) was carried out with a consecutive sample of 386 patients admitted during one year to a medical centre in Taiwan for a 3-day comprehensive general health screening. The Chinese version of the Clinical Interview Schedule was used to derive a criterion measure of minor psychiatric morbidity. The areas under the Relative Operating Characteristic curves of both short versions of the CHQ were equivalent (area = 0.85, S.D. = 0.02). The sensitivities of the CHQ-30 and CHQ-12 were found to be 76 and 78% respectively, while the specificity of both was 77%. The estimated prevalence of minor psychiatric morbidity in the sample was 37% (95% confidence intervals 32-41%). In contrast, physicians diagnosed 11% of these patients as having psychiatric disorders, and their sensitivity was 29%. Taken altogether, the above findings suggest that the CHQ-12 is as effective as and is more efficient than the CHQ-30 in this context, and could be used by physicians in similar settings to improve their identification of minor psychiatric disorders in Chinese patients.
对中国健康问卷（CHQ）的30项和12项版本的有效性进行了一项研究，研究对象为连续一年入住台湾某医疗中心进行为期3天全面综合健康筛查的386例患者。采用中文版临床访谈时间表得出轻度精神疾病的标准测量值。CHQ两个短版本的相对操作特征曲线下面积相当（面积=0.85，标准差=0.02）。发现CHQ - 30和CHQ - 12的敏感性分别为76%和78%，而两者的特异性均为77%。样本中轻度精神疾病的估计患病率为37%（95%置信区间32 - 41%）。相比之下，医生将这些患者中的11%诊断为患有精神疾病，其敏感性为29%。总体而言，上述研究结果表明，在这种情况下，CHQ - 12与CHQ - 30一样有效且效率更高，医生在类似环境中可使用它来提高对中国患者轻度精神疾病的识别能力。
