摘要
目的:在行为科学的测量模型的研究中,双因素模型近年来再次引起学者们的广泛关注,双因素模型比起单因素模型、多因素模型以及二阶因子模型有着其独特的优势。本文的主要目的是介绍双因素模型,并利用双因素的模型结构再一次检验特质乐观的测量模型。方法:以班级为单位整群取样的方法抽取377名大学生,施测Scheier等修订的生活取向量表(LOT-R)。采用验证性因素分析的方法,比较单因素模型、两因素模型以及双因素模型的特质乐观结构。结果:特质乐观的双因素模型比两因素模型以及单因素模型都拟合得更好,各项拟合指标都是最优的。结论:在特质乐观的结构模型中,可以考虑选择双因素模型。
Objective： The main purpose of this paper was to introduce the bifactor model, and to use it to test the structure of the measurement model of dispositional optimism. Methods： By convenient sampling, 377 graduated students were investigated with Life Orientation Scale（LOT-R）. Comfirmatory factor analysis was applied to compare the structure of one-factor model, two-factor model and bifactor model. Results： The bifactor model had the best fitting index to test dispositional optimism. Conclusion： We would consider to choose bifactor model to measure dispositional optimism.
