背景资料。近年来，由12个条目组成的一般健康问卷(GHQ-12)被广泛用作一种简短的筛查工具，其结果可与较长版本的GHQ相媲美。在世界卫生组织对一般卫生保健中的心理障碍的研究中，将GHQ-12的有效性与GHQ-28进行了比较。使用CIDI-PC的初级保健版本的综合国际诊断仪器对15个中心的5438名患者进行了访谈。结果一致良好，ROC曲线下面积平均为88，范围为83~95。用于定义病例的标准的微小变化对GHQ的有效性几乎没有影响，复杂的评分方法并不比简单的方法提供任何优势。为了本研究的目的，GHQ被翻译成10种其他语言，效度系数几乎与原始语言一样高。在发展中国家，没有降低总部工作效率的趋势。性别、年龄、文化程度对量表的效度无显著影响。如果调查人员希望使用筛查仪器作为病例探测器，较短的GHQ非常坚固，工作起来与较长的仪器一样好。只有在对总分以外的分级分数感兴趣的情况下，才应优先选择后者。
Background. In recent years the 12-item General Health Questionnaire (GHQ-12) has been extensively used as a short screening instrument, producing results that are comparable to longer versions of the GHQ.Methods. The validity of the GHQ-12 was compared with the GHQ-28 in a World Health Organization study of psychological disorders in general health care. Results are presented for 5438 patients interviewed in 15 centres using the primary care version of the Composite International Diagnostic Instrument, or CIDI-PC.Results. Results were uniformly good, with the average area under the ROC curve 88, range from 83 to 95. Minor variations in the criteria used for defining a case made little difference to the validity of the GHQ, and complex scoring methods offered no advantages over simpler ones. The GHQ was translated into 10 other languages for the purposes of this study, and validity coefficients were almost as high as in the original language. There was no tendency for the GHQ to work less efficiently in developing countries. Finally gender, age and educational level are shown to have no significant effect on the validity of the GHQ.Conclusions. If investigators wish to use a screening instrument as a case detector, the shorter GHQ is remarkably robust and works as well as the longer instrument. The latter should only be preferred if there is an interest in the scaled scores provided in addition to the total score.
