摘要
目的:本研究的目的是在中国大陆和中国香港的大学生人群中,进一步检验中译版《锻炼行为调节问卷-2》(C-BREQ-2)的相关心理测量学属性。方法:来自中国大陆(n=191)和中国香港(n=194)的大学生参加了本次研究,检验了C-BREQ-2的因素效度、区别效度、法则效度、内部一致性信度以及测量恒等性。结果:验证性因素分析结果为18条目C-BREQ-2的5因素结构提供了支持。因素间相关程度的95%置信区间检验表明,C-BREQ-2各因素间虽具有相关性但属不同概念,这为区分效度提供了支持。C-BREQ-2的内部一致性信度达到可接受水平。不同行为调节因素间相关系数呈简单相关模式,为C-BREQ-2的法则效度提供了支持。不同行为调节变量与情感及行为变量间的相关结果符合理论假设,进一步对其法则效度提供了支持。多组验证性因素分析结果表明,在中国大陆和中国香港大学生中,C-BREQ-2测量模型的因子载荷和因子方差/协方差具有跨人群恒等性。结论:本研究为在中国大学生人群使用C-BREQ-2进一步提供了心理测量学证据,也使得以自我决定理论为基础的相关动机理论在中国人人群以及在锻炼和体力活动等领域的进一步研究与应用成为可能。
Purpose： The purpose of the study was to examine the psychometric properties of the Chinese-translated Behavioral Regulation in Exercise Questionnaire-2 （C-BREQ-2） among Chinese university students from the Mainland and Hong Kong of China. Methods： University students from the Mainland （n = 191） and Hong Kong （n=194） of China participated in this study. Factorial validity, discriminant validity, nomological validity, internal reliability, and measurement invariance across sample of the C-BREQ-2 were examined. Results： Confirmatory factor analysis provided support for the factorial validity of the 18-item, 5-factor structure C-BREQ-2. Examination of the 95% confidence interval of the inter-factor correlations suggested that the C-BREQ-2 assesses related but distinct constructs, which provided support for its discriminant validity. The internal consistency reliability of the C-BREQ-2 was found acceptable. Examination of the pattern of inter-factor correlations between different regulations suggested that a simplex-like pattern was displayed, which provided evidence for the nomological validity of C-BREQ-2. The results from multi-group confirmatory factor analysis suggested that the factor loadings and variances/ covariances of the C-BREQ-2 measurement model were invariant across the Chinese university students in the Mainland and Hong Kong of China. Conclusion： The current study provided further psychometric evidence for the C-BREQ-2, which makes the further application and research of self-determination theory （SDT） based motivation in relation to exercise and physical activity in the Mainland of China context possible.
