Transcultural adaptation of Odia version of health-related kidney disease and quality of life-36 instrument

Abstract

Objective: The study objective was to translate, validate, and test the reliability of the original kidney disease and quality of life-36 (KDQOL-36™) instruments in Odia. Materials and Methods: A cross-sectional design with a purposive sampling technique was used. According to RAND Corporation guidelines, initially, the items of the KDQOL-36™ questionnaires were translated into Odia by two independent, bilingual, professional translators, and then back-translated to English, followed by tryout and field testing. The experts validated the KDQOL-36™ instrument review committee for review related to kidney health conditions. The tool was implemented among 180 patients undergoing “maintenance” hemodialysis. The following tests evaluated reliability and validity: test–retest reliability with Cronbach’s alpha correlation (stability), (reliability) internal consistency, and contents validity index. Results: The Cronbach’s alpha value and intraclass correlation coefficient (ICC) score of all five domains, namely “physical component summary, mental component summary (MCS), the burden of kidney disease, symptoms and problems of kidney disease, and effects of kidney disease” of both KDQOL-36™ English and Odia (KDQOL-36-E™ and KDQOL-36-O™) version, recommended excellent homogeneity. A high positive correlation (r = 0.998) was found between the Odia version of KDQOL-36™ and the English version KDQOL-36™ questionnaire. The ICC score ranges from 0.889 to 0.997 at a 95% confidence interval for test–retest reliability, and Cronbach’s alpha was 0.832. Conclusion: This study explores the Odia version of KDQOL-36™ psychometric properties, depicted at an acceptable level of internal consistency. The KDQOL-36-O™ instrument is a valid and reliable tool for assessing the kidney disease-related quality of life in Odia-speaking hemodialysis patients.
