The General Health Questionnaire (GHQ) was designed by Goldberg in the 1970's as a screening instrument to provide information on the mental wellbeing. Although it is widely used as a unidimensional instrument, factor analyses tend to suggest that it contains more than one dimension.
The purpose of this paper is to review the factor-analytic research that has been carried out with regard to the 30-item General Health Questionnaire (GHQ-30) and to present the results of the analysis of our research.
A total of 623 patients suffering from neurotic disorders and somatic illnesses were included into the study, 130 men and 493 women at the age ranged from 17 to 85 years old. A total score was calculated with Likert's method. The principal factor analysis with orthogonal varimax normalised rotation was used. Results. The GHQ-30 was found to have high internal consistency as a scale and high item-total correlations for most of the items. The factorial analysis showed that three factors labelled as the followed can be abstracted from the scale: depression and anxiety, interpersonal relations, general functioning. These factors jointly account for 58% of the variance.
Results showed both multifactorial (at the level of a lower order) and unifactorial (at the level of an upper order) structure of the GHQ-30.
一般健康问卷(GHQ)由戈德堡于20世纪70年代设计,作为一种筛查工具,用于提供有关心理健康的信息。尽管它被广泛用作单维工具,但因素分析往往表明它包含多个维度。
本文旨在回顾针对30项一般健康问卷(GHQ - 30)进行的因素分析研究,并呈现我们研究的分析结果。
共有623名患有神经症和躯体疾病的患者纳入研究,其中130名男性和493名女性,年龄在17至85岁之间。采用李克特法计算总分。使用具有正交方差最大化归一化旋转的主因素分析。结果。发现GHQ - 30作为一个量表具有较高的内部一致性,且大多数项目的项目总分相关性较高。因素分析表明,可以从该量表中提取出三个因素,分别标记为:抑郁与焦虑、人际关系、总体功能。这些因素共同解释了58%的方差。
结果显示了GHQ - 30的多因素(在较低层次)和单因素(在较高层次)结构。
