The objective of this study is to conduct a thorough assessment of the psychometric properties and measurement consistency of the Behavioural Regulation in Exercise Questionnaire-2 in a sample of adolescents from Mainland China. This research project involves recruiting 350 middle and high school students to conduct a thorough assessment of internal consistency and discriminant validity. The methods used include confirmatory factor analysis and multi-group confirmatory factor analysis. In addition, the study examines the consistency of these measures among various genders and educational backgrounds. The findings indicated that the students' motivation levels were moderately high, as evidenced by the internal consistency coefficients ranging from 0.818 to 0.903 for the subscales. The confirmatory factor analysis provided strong evidence for a 5-factor structure, as indicated by the satisfactory fit indices (CFI = 0.972, RMSEA = 0.046). Also, the measurement invariance tests demonstrated the stability of the factors across various genders and academic groups (ΔCFI < 0.01). The results of this study confirm the effectiveness of the Behavioural Regulation in Exercise Questionnaire-2 as a valuable tool for evaluating exercise motivation regulation among young individuals in Mainland China. This reinforces the tool's usefulness for future scholarly research as well as its practical application in educational and developmental settings.
