目的:检验心理健康自评问卷(self-reporting questionaire 20,SRQ-20)中文版的信效度。方法:在地震发生3周后,向675名都江堰市高三学生施测了SRQ-20和贝克抑郁量表第二版(Beck Depression Inventory-2nd Edition,BDI-Ⅱ)。用Kuder-Richardson公式计算SRQ-20内部一致性系数。计算各个项目与总分的点二列相关。用探索性因素分析检测SRQ-20的因子结构。用SRQ-20和BDI-Ⅱ的相关进行聚合效度的检验。结果:KR-20系数为0.79。项目和总分的相关在0.34到0.60之间,平均达到了0.48。SRQ-20和BDI-Ⅱ之间的相关为0.70。探索性因素分析得到4个因子,解释总方差的43.96%。除了项目1和5,其他项目的因子载荷均高于或接近0.40。结论:心理健康自评问卷的一致性信度和效标关联效度良好,但其因子结构尚不稳定,暂不适宜将其因子当作子量表应用,而应视为单维处理。

Objective:To provide information about some of the psychometric characteristics of Self-Reporting Questionnaire(SRQ-20,Chinese version).Methods:The Chinese verison of SRQ-20 and Beck Depression Inventory-2nd Edition(BDI-Ⅱ)were administered to 675 students who were about to take the national college entrance exam in Dujiangyan city,three weeks after the earthquake.Kuder-Richardson formulation was employed to estimate the inter-consistency of SRQ-20.And point-biserial correlation was calculated to indicate the item-total consistency.Exploratory factor analysis was conducted to examine the factorial construct.Moreover,the test of the association between the scores of SRQ-20 and BDI-Ⅱwas used to provide evidence of convergent construct of this instrument.Results:The KR-20 coefficient of the scale was 0.79.The item-total score correlations varied from 0.34 to 0.60,averagely reached 0.48.The correlation between the score of SRQ-20 and BDI- was 0.70.Exploratory factor analysis yielded a four-factor construct which explained 43.96% of total variance.Except item 1 and 5,the factor loading of the remained items were more than or near to 0.40.Conclusion:The results suggest the consistency reliability and criteria validity of Chinese SRQ-20 are adequate.However,the results of factor analysis from different researches are not consistent.This implies that it’s more advisable to regard the scale as one-dimension rather than use the factor structure as sub-scales.
