在这项研究中，作者使用验证性因素分析，在西班牙产后妇女样本中测试了 12 项一般健康问卷 (GHQ-12) 的替代因素模型。作者报告了使用分类数据和二进制数据推荐的估计方法对三种不同的 GHQ-12 评分方法进行建模的结果。还进行了判别函数分析来测试多因素模型的实用性。设计了一项两阶段横断面研究：(a) 1,453 名产后 6 周来访的妇女完成了 GHQ-12 和爱丁堡产后抑郁量表问卷，(b) 根据爱丁堡产后抑郁量表结果，对参与者进行分层，并在每个层中随机选择参与者进行临床评估。使用李克特式评分方法，汉金斯具有“方法效应”的单因素模型获得了最佳拟合。此外，格雷茨的三因素模型在诊断组之间几乎没有区分，这些因素高度相关。这些结果支持 GHQ-12 中仅存在一种潜在因子。
In this study, the authors tested alternative factor models of the 12-item General Health Questionnaire (GHQ-12) in a sample of Spanish postpartum women, using confirmatory factor analysis. The authors report the results of modeling three different methods for scoring the GHQ-12 using estimation methods recommended for categorical and binary data. A discriminant function analysis was also performed to test the utility of a multiple factor model. A two-phase cross-sectional study was designed: (a) 1,453 women visiting at 6 weeks postpartum completed the GHQ-12 and the Edinburgh Postnatal Depression Scale questionnaire and (b) based on the Edinburgh Postnatal Depression Scale outcomes, participants were stratified and randomly selected within each stratum for clinical evaluation. Using the Likert-type scoring approach, Hankins's one-factor model with "method effects" obtained the best fit. In addition, Graetz's three-factor model provided little discrimination between diagnostic groups, the factors being highly correlated. These results support the presence of only one latent factor in the GHQ-12.
