Abstract Funding Acknowledgements Type of funding sources: Private grant(s) and/or Sponsorship. Main funding source(s): Indonesia Ministry of Health Background HeartQoL questionnaire was developed to measure specific health-related quality of life for post-myocardial infarction patients. However, it has not been adapted and tested for its validity and reliability for Indonesian population. Purpose To assess the validity and reliability of the Indonesian version of the HeartQoL Questionnaire in post-acute myocardial infarction patients. Method We admitted 102 Indonesian-native speaking patients treated at a tertiary hospital who experienced the first episode of acute myocardial infarction (93% male; mean age = 56.8 years) into the study. They were randomly contacted to fill out the Indonesian version of HeartQoL and SF-36 questionnaire independently. Construct validity of the HeartQoL questionnaire was analyzed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and convergent validity was assessed by correlation of the HeartQoL and SF-36 similar subscales, whereas internal consistency was examined using Cronbach's Alpha value. Results EFA showed that the Indonesian version of HeartQoL consisted of 14-items with a 2-factor structure, and CFA supported the results by showing a satisfactory fit, CFI = 0.972, TLI = 0.961, and RMSEA = 0.075. Convergent validity was shown by r > 0.50 for physical and mental domain. The internal consistency of the HeartQoL scales was indicated by the Cronbach's Alpha value of 0,865-0.953. Conclusions The Indonesian version of the HeartQol questionnaire is a valid and reliable measure to assess the quality of life of patients after myocardial infarction.
