Validity and Reliability of the Peds QLᵀᴹ 4.0 Generic Core Scale in Indonesian Version in Children with Chronic Kidney Disease Undergoing Hemodialysis in the Dialysis Unit of Cipto Mangunkusumo Hospital

Abstract

Background: The Peds QLᵀᴹ 4.0 Generic Core Scales is a modular instrument for measuring health-related quality of life (HR-QoL) in children and adolescents aged 2 to 18 years. The Peds QLᵀᴹ 4.0 GCS consists of 23 items applicable to healthy school and community populations and populations of children with acute and chronic health conditions. The Pediatric Quality of Life Inventory (Peds QLᵀᴹ 4.0 Generic Core Scales) is a modular instrument designed to measure health-related quality of life (HR-QoL) in children and adolescents aged between two and thirteen years. It measures health-related quality of life (HR-QoL) in children and adolescents with progressive chronic kidney disease (CKD), regardless of the underlying etiology, due to the need for regular follow-up visits, strict medication regimens, and dietary intake. Purpose: This study aimed to evaluate the validity and reliability of the Peds QLᵀᴹ 4.0 GCS Indonesian version in children with CKD undergoing hemodialysis (HD) in the Dialysis Unit of Cipto Mangunkusumo Hospital. Methods: This type of research is analytical and observational in nature. The Peds QLᵀᴹ 4.0 GCS were administered to 30 children and 30 parents recruited from a pediatric dialysis unit. This study was conducted at a pediatric dialysis unit at Cipto Mangunkusumo Hospital Jakarta, Indonesia, in Mei-Juni 2024. Validity was tested using Pearson product moment, and reliability was tested using Cronbach's alpha. Results: A total of 30 children and 30 parents undergoing hemodialysis agreed to participate. The average age of the patients was 8–18 years old. Cronbach’s alpha coefficient for the total Peds QLᵀᴹ 4.0 GCS (α child self-report 0.918; α parent proxy report 0.928). Conclusion: The Indonesian versions of The Peds QLᵀᴹ 4.0 GCS were valid and reliable instruments to measure the HR-QoL of children with CKD on hemodialysis. The Peds QLᵀᴹ 4.0 GCS can be applied to provide relevant evidence that helps the function of quality of life among Indonesian patients on hemodialysis in evaluating health programs.
