Introduction: Little is known about the quality of life of children with disabilities (CWD). To the best of our knowledge, there is no validated instrument to measure the quality of life of CWD in Malaysia.
Objective: The objective of this cross sectional study was to determine the reliability of the Malay version of the Quality of Life Inventory ™ Version 4.0 (PedsQL) Generic Core Scales among CWD in Kelantan.
Methods: A cross sectional study was conducted in September 2009 among CWD aged between two to eighteen years old, registered with the Kelantan Foundation for the disabled. Parent-proxy report was used. The test for Cronbach’s alpha was performed to determine the internal consistency reliability
Results: There were a total of 78 CWD involved in this study. The internal consistency reliability was good as the Cronbach’s alpha of all domains were above 0.6, ranging from 0.65 to 0.85.
Conclusions: The Malay Version of the Pediatric Quality of Life Inventory ™ Version 4.0 (PedsQL) Generic Core Scales shows good internal consistency reliability. However, future study with bigger sample size is necessary before it may be recommended to be used as a tool to measure the quality of life of CWD whose parents understand the Malay language.
