Background The PedsQL 3.0 End Stage Renal Disease (ESRD) Module is a well-accepted instrument internationally but it is not available in the local language. We aimed to validate the Bahasa Melayu (Malay language) version and determine the health-related quality of life (HRQoL) scores amongst children with CKD in Malaysia. Methods The source questionnaire in English was translated into Bahasa Melayu. Linguistic validation guidelines by the MAPI Research Institute were followed. The already validated Bahasa Melayu PedsQL 4.0 Generic Core Scales was used for comparison. Sociodemographic data were collected during the interview. Statistical analyses were performed using SPSS version 25.0. Results Sixty-nine children aged 8 to 18 with CKD stages 4 and 5, with or without dialysis, and their caregivers were recruited. Mean age was 12.62 +/- 2.77 (SD). Evaluation of the PedsQL 3.0 ESRD Module Bahasa Melayu version demonstrated good internal consistency (Cronbach alpha 0.82). There was good agreement between child self-report and parent proxy report in all domains; average intraclass correlation coefficients (ICC) were 0.78, 95% CI (0.71, 0.84). Scores obtained from Generic 4.0 scales correlated with the disease-specific ESRD 3.0 scale, Spearman's rho = 0.32, p= 0.007. The Kruskal-Wallis H test indicated that there were no significant differences between stages of CKD and their respective mean HRQoL score, chi(2)(2) = 2.88, p= 0.236. Conclusions The PedsQL 3.0 ESRD Module Bahasa Melayu version is a reliable and feasible tool for cross-cultural adaptation. A longer prospective study may help better illustrate the quality of life in this group of children.
