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.展开更多

Methods: The model of FGR was established by passive smoking method to pregnant rats. The new-born rats were divided into FGR group and normal group, and then randomly subdivided into trained and untrained group respectively. Morris water maze behavior training was performed on postnatal months 2 and 4, then learning and memory abilities of young rats were measured by dark-avoidance testing and step-down testing. Results: In the dark-avoidance and step-down testing, the young rats’ performance of FGR group was worse than that of control group, and the trained group was better than the untrained group significantly. Conclusion: FGR young rats have descended learning and memory abilities. Behavior training could improve the young rats’ learning and memory abilities, especially for the FGR young rats.展开更多
