This study tested alternative factor models of the General Health Questionnaire-12 (GHQ-12), based on previous research findings, with a large sample using confirmatory factor analysis. An alternative models framework was used to test 6 factor analytic models. A 3-factor model was the best explanation of the sample data. The 3 factors were labeled Anxiety-Depression, Social Dysfunction, and Loss of Confidence. The model was found to be factorially invariant between men and women. The utility of the 3 subscales, as opposed to the total GHQ-12 score, is questioned as they appear to provide little information beyond that of a general factor.
本研究基于先前的研究结果，使用验证性因素分析对大量样本进行了一般健康问卷12项（GHQ - 12）的替代因素模型测试。采用替代模型框架对6个因素分析模型进行了测试。一个三因素模型是样本数据的最佳解释。这三个因素分别被标记为焦虑 - 抑郁、社会功能障碍和信心丧失。该模型在男性和女性之间具有因素不变性。与GHQ - 12总分相比，这三个分量表的效用受到质疑，因为它们似乎除了一般因素之外几乎没有提供更多信息。
