The Translation, Culture-Adaptation and Psychometric Evaluation of the Cardiac Rehabilitation Barriers Scale Among Chinese Older Population.

PURPOSE

This study aimed to translate and cross-culturally adapt the cardiac rehabilitation barriers scale to the Chinese, and examine its reliability and validity among the older population.

METHODS

An approach comprising translation, cultural adaptation, reliability, and validity examination in the Chinese version was conducted in two hospitals in Jilin, China. The -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 (χ2/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.
