一般健康问卷-12是一种广泛使用的筛查工具，用于检测一般人群的心理压力。PsycInfo数据库的文献检索提取了自1990年以来使用GHQ-12的167项研究。调查GHQ-12因子结构的文献主要依赖于传统的因子分析方法，其结果是不确定的。文献中有证据支持GHQ-12的一维、双因素和三因素概念化。在本文中，我们评估的GHQ-12的因素结构的一个因素，两个因素和三个因素的解决方案，使用结构方程模型和纵向数据集来自23个大型新西兰组织的充分性。结果有利于一个双因素模型，包括一个“社会功能障碍”的因素和“焦虑/抑郁”的因素测量的四个项目。通过与五个标准变量的相关性分别评估两个因素的同时效度，所有相关性均在预期方向。使用GHQ-12的研究的理论意义进行了讨论。版权所有（C）2004约翰威利父子有限公司。
The General Health Questionnaire-12 is a widely used screening instrument for detecting psychological strain in the general population. A literature search of the PsycInfo database extracted 167 studies that used the GHQ-12 since 1990. The literature investigating the factor structure of the GHQ-12 has relied primarily on conventional factor analysis methods, the results of which are inconclusive. There is evidence in the literature supporting unidimensional, two-factor and three-factor conceptualizations of the GHQ-12. In the present paper we assess the adequacy of the factor structure of the GHQ-12 for one-factor, two-factor and three-factor solutions, using structural equations modelling and a longitudinal dataset drawn from 23 large New Zealand organizations. The results favour a two-factor model consisting of a 'Social Dysfunction' factor and an 'Anxiety/Depression' factor measured by four items each. Concurrent validity of the two factors was assessed separately through correlations with five criterion variables, and all correlations were in the expected direction. Theoretical implications for research using the GHQ-12 are discussed. Copyright (C) 2004 John Wiley Sons, Ltd.
