Reliability Testing of Self-Care of Heart Failure Index v6.2 Chinese Instrument Among Heart Failure Patients
Main Article Content
Objective: Self-Care of Heart Failure Index (SCHFI) v6.2 Chinese is an instrument used to assess the ability of self-care behaviour among heart failure patients. It has been validated in Taiwan, however, it is yet to be validated in Malaysia. As a multi-ethnic country, Chinese language has been one of the major languages in Malaysia. Therefore, this study was conducted to examine the reliability of Self-Care of Heart Failure Index (SCHFI) v6.2 Chinese among Malaysian population.
Design: A successive independent sample design was used throughout a 4-months data collection period.
Setting: Eighty heart failure patients from University of Malaya Medical Centre and National Heart Institute were recruited through purposive sampling. The two hospitals were chosen because they have specialized heart clinics that eased the data collection. The out-patients were screened by the cardiologists for their eligibility to participate in this study.
Measures: The samples were administered with SCHFI v6.2 Chinese. The item endorsement index, internal consistency and item-total correlation of SCHFI v6.2 Chinese were examined.
Results: The maintenance subscale of SCHFI showed a low internal consistency (Cronbach α = .52) while the management and confidence subscales showed an acceptable internal consistency (Cronbach α = .67 and .90 respectively).
Conclusion: SCHFI v6.2 Chinese is a reliable instrument to be used among the Malaysian population.
