Overview

Background: The Kansas City Cardiomyopathy Questionnaire (KCCQ) is the most specific and widely used questionnaire for assessing health-related quality of life (HRQoL) in chronic heart failure (CHF). This study aimed to examine reliability and validity of the KCCQ in Arabic patients with CHF. Material and Methods: Patients with CHF filled out the Arabic versions of the Minnesota Living with Heart Failure (MLHF) and KCCQ questionnaire, and performed a six-minute walk test (6MWT) on their first visit. On the return, the patients filled out the KCCQ along with the global rating of change (GRC) scale. Internal consistency, test–retest reliability, and construct validity were examined. Results: A total of 101 Arabic patients with CHF, with a mean (SD) age of 55 (11) years old, completed the study. The Cronbach’s alpha was 0.97, and the ICC2,1 = 0.95 (95%CI: 0.92 to 0.97, p < 0.001). The Arabic version of KCCQ was correlated with the MLHF (r = −0.57, p = 0.01) and with the 6MWT (r = 0.70, p < 0.001). Conclusions: The Arabic version of KCCQ is a reliable and valid measure of HRQoL, which could be utilized in routine clinical practice for Arabic-speaking patients with CHF.
