The t-tests were used to compare the sex differences between each item. Participants included Chinese individuals > 60 who were eligible for the cardiac rehabilitation program.Results: In total, 325 participants completed the questionnaire with an average age of 61.23 ± 9.68 years. The item-total correlations were 0.432 to 0.678. Factor analysis of CRBS-C (Kaiser Meyer Olkin = 0.867, Bartlett’s test p = 0.000) revealed four factors: logistical factors, comorbidities/functional status, perceived need/healthcare factors, and work/time conflict. The confirmatory factor analysis (CFA) indicated a good model fit (χ 2/df = 1.84, RMSEA = 0.051, CFI = 0.953, TLI = 0.945, SRMR=0.046). Cronbach’s alpha was 0.88 for the scale, ranging from 0.801 to 0.88 for each item, which indicates the internal reliability was acceptable.Conclusion: The Chinese version of the CRRS has acceptable reliability and validity in the Chinese elderly population.Keywords: cardiac rehabilitation, internal reliability, cross-cultural adaptation, exploratory factor analysis, confirmatory factor analysis
