Reliability and validity of the behavioral regulation in exercise questionnaire-2 for nursing home residents in China

Abstract Purpose To examine the reliability and validity of the Chinese-translated Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) for nursing home residents. Methods A convenience sample of 204 nursing home residents were used for measuring the instrument performances. Demographics form and BREQ-2 developed by Markland were applied. Results The translated BREQ-2 model was a good fit for the results of confirmatory factor analysis, χ2 was 276.75, comparative fit index was 0.941, standardized root mean square residual was 0.048 and root mean square error of approximation was 0.068. Results in the BREQ-2 indicated good consistency, Cronbach’s α coefficient of BREQ-2 was 0.78 and each of the five subscales were ranged from 0.78 to 0.83. The test–retest was valued 0.84 and the five subscales were ranged from 0.75 to 0.89 which supporting the stability of instrument. Conclusion This study provided psychometric evidence for the application of BREQ-2 among nursing home residents in China.
