Abstract

Purpose
The Cardiac Rehabilitation scale (INCR scale) is a verified measure worldwide. The scale measures the extent to which cardiac rehabilitation meets the various needs of the participating patients and determines how education related to heart disease and rehabilitation satisfies their preferences. The current study applied the INCR scale to verify and develop it for use in Korea by conforming to Korean culture and language.
Methods
The Korean version of the INCR scale was created after a six-step process in accordance with the international questionnaire translation law. The Korean version of the INCR scale was assessed in 45 cardiac rehabilitation patients (29 males, 16 females). Internal consistency was verified using Cronbach’s alpha. Test-re-test reliability and interrater reliability were verified using the intraclass correlation coefficient (ICC). Content validity was selected to verify the validity.
Results
The content validity index of the Korean version of the INCR scale was high, with an average of 0.93. Cronbach’s Alpha for Internal consistency also revealed high reliability of 0.89 in all 10 categories. The interclass correlation coefficient of the test-re-test and interrater reliability scores were 0.95 and 0.81, respectively.
Conclusion
Our results indicate that the Korean version of the INCR scale would be instrumental in the clinical setting to determine the knowledge, educational needs, and preferences of patients participating in cardiovascular disease and cardiac rehabilitation.
