عنوان انگلیسی Translation and Cross-Cultural Adaptation, Reliability and Validation Study of the Persian Version of Kansas City Cardiomyopathy Questionnaire
چکیده انگلیسی مقاله The Kansas City Cardiomyopathy Questionnaire (KCCQ) has been developed to measure the health status of Congestive heart failure (CHF) patients. This study aimed to translate KCCQ into a Persian version and assess its validity and reliability. We used a forward-backward procedure to translate the questionnaire. In a cross-sectional study, 150 CHF patients and 50 healthy subjects over 30 years old were selected to assess the reliability and construct validity of the instrument. The face and content validity were used for the questionnaire's validity. The validity was examined on a population of patients with CHF using the Persian version of the Minnesota Living Heart Failure Questionnaire (MLHF) health survey. Calculation of the Intraclass correlation coefficient (ICC) and Cronbach's alpha was done to evaluate the questionnaire's reliability. Test-retest reliability was examined by re-administering the KCCQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all domains was higher than 0.93, P≤0.000). Internal consistency was found by Cronbach's alpha to be 0.86 for the clinical summary and 0.87 for the overall summary, respectively. Also, the correlation between the components of KCCQ and MLHQ showed satisfactory construct validity. Good Pearson's Correlation Coefficient was seen between KCCQ and MLHF (r= -0.44, P≤0.000 for the clinical summary; r= -0.45, P≤0.000 for the overall summary). Analysing the data from 50 healthy persons and 150 patients were shown that the Persian version of KCCQ has acceptable discriminate validity for all domains except self-efficacy. The Persian version of the KCCQ had satisfactory reliability and validity for assessing health-related quality of life status for Iranian CHF patients.
