Basic mental health vital statistics are scarce in developing countries. Scarcer still are validated psychological survey instruments which can be used in these settings. A method of dealing with such scarcity is through the validation of instruments developed elsewhere. One such instrument is Goldberg GHQ-30. The 30-item General Health Questionnaire was used by the authors as a screening instrument for emotional disorder in a general medical outpatient clinic. The GHQ-30 misclassified 32.3% of the respondents, a majority of whom were false-positives. There is a tendency for the misclassified respondents to suffer from chronic physical ailments, and to be older. The GHQ-30 appears not to have high specificity (65%) and sensitivity (73%). The predictive value (53.3%) of a positive finding by this screening instrument in this population is also low. Informed consent was obtained from participating subjects.
发展中国家基本的心理健康重要统计数据匮乏。在这些环境中可使用的经过验证的心理调查工具更是稀缺。应对这种稀缺状况的一种方法是对在其他地方开发的工具进行验证。其中一种工具是戈德堡GHQ - 30。作者将这份包含30个条目的一般健康问卷用作综合内科门诊中情绪障碍的筛查工具。GHQ - 30将32.3%的受访者误分类，其中大多数为假阳性。被误分类的受访者倾向于患有慢性身体疾病且年龄较大。GHQ - 30似乎没有很高的特异性（65%）和敏感性（73%）。该筛查工具在这一人群中阳性结果的预测价值（53.3%）也很低。已获得参与研究对象的知情同意。
