摘要
目的:针对心理素质层次因子结构模型容易混淆了各层次因子间的特殊效应和共同效应的缺陷,采用双因子模型对中小学生心理素质结构进行探讨,以期能更好的揭示中小学心理结构的实质,验证此前我们提出的心理素质结构的理论构想。双因子模型用一个全局因子反映多个维度的共同性,用多个局部因子解释特殊效应。方法:采用整群抽样的方法先后两次抽取529名小学生、2106名中学生以及1191名小学生、2254名中学生,构建心理素质双因子模型,并采用似然比检验比较双因子模型与层次因子模型的拟合优劣。结果:心理素质的双因子模型比层次因子模型的拟合更好,各项拟合指标均最佳。结论:双因子模型适用于解释中小学生心理素质的结构。
Background:Previous confirmatory factor analytic research that has examined the factor structure of the psychological suzhi has endorsed either higher order models or oblique factor models that tend to amalgamate both general factor and index factor sources of systematic variance. The bifactor model-an alternative model-has not been examined for the psychological suzhi. Purpose: The structure of psychological suzhi was validated using bifactor model in present study. Method: Chester sampling was adopted for two times to build the bifactor model for psychological suzhi. In the first time 529 pupils and 2106 middle school students were selected; in the second time, 1191 pupils and 2254 middle school students were selected. Likelihood-ratio test was adopted to compare the bifactor model with the traditional hierarchical factor model for their goodness/badness of fit. Results: The bifactor model fit the data significantly better than the second-order model and oblique factor model. Conclusion: The bifactor model is applicable to interpret the structure of psychological suzhi.
