This analysis re-examines the factor structure of the 12-item GHQ for a large Australian sample of young people. It shows that oblique factor rotation better approaches the criterion of simple structure, and allows separate components of the GHQ to be identified and measured using factor scores. When the performance of these separate factors is compared with composite Likert scores, it is found that they do not behave uniformly in response to outside variables, both in cross-sectional and longitudinal analyses. These results suggest that there are advantages to be gained by using the multidimensional properties of the GHQ as well as a single severity score. The additional information this yields can provide new insights into the nature of psychiatric impairment within and between samples.
本分析重新审视了针对大量澳大利亚年轻人样本的12项一般健康问卷（GHQ）的因子结构。结果表明，斜交因子旋转能更好地接近简单结构的标准，并允许使用因子得分来识别和测量GHQ的各个组成部分。当将这些单独因子的表现与李克特综合得分进行比较时，发现在横断面分析和纵向分析中，它们对外部变量的反应并不一致。这些结果表明，利用GHQ的多维属性以及单一严重程度得分具有优势。由此产生的额外信息可以为样本内部和样本之间精神障碍的本质提供新的见解。
