大学生体育锻炼行为结构的验证性因素分析

University students＇ sports exercise behavior structure： a confirmatory factor analysis

目的以计划行为理论为依据，构建大学生体育锻炼行为结构模型，为大学生养成终生体育锻炼习惯提供策略。方法在文献回顾及问卷调查的基础上，利用结构方程建模（AMOS4．0）技术，对560名大学生体育锻炼行为的测试结果进行验证性因素分析。结果大学生锻炼行为是由行为意向、主观标准、认知行为控制以及综合态度四个维度构成，模型四个维度的CFI、IFI、NFI等指标均在0．90以上；RMSEA分别为0．056和0．042；而且二阶因子与一阶因子的关系也很强（GA值为0．62，0．58，0．51，0．75），△X^2（2）=2．73（P〉0．05）。因此，在优化了大学生体育锻炼行为一阶4因素模型的基础上，建立了二阶1因素一阶4因素结构模型。结论大学生体育锻炼行为结构模型的验证，无论从拟合指数方面，还是理论假设方面都证明了模型的适度性，同时为大学生体育锻炼行为诊断提供依据。

ObjeCtive To construct a measuring scale for sports exercise behavior of college students based on Ajzen＇s planned behavioral theory. Methods A confirmatory factor analysis was conducted on the result of the test on the sports exercise behavior of 560 college students. Results The behavior is composed of four factors： behavioral intention, subjective standards, cognitive behavior and integrated attitude. The index of CFI, IFI, NFI is above 0.90 ; and RMSEA is 0. 056 and 0. 042, so the relationship between second-order factor and first-order factor is strong （ GA is 0.62, 0.58, 0.5 1, 0.75） , △X^2 （2） = 2.73 （ P 〉 0.05）. On the basis of the first-order factor, a second-order factor structural model was established, together with a measuring scale for sports exercise behavior of college students. Conclusion The construction of measuring scale for sports exercise behavior of college students has proved that it is appropriate, and provided a basis for college students to do exercises.
