Background: The Cerebral Palsy Quality of Life for Children (CP QOL-Child) questionnaires are condition-specific QOL measures for children with CP focusing on perspectives of children with CP on their quality of life, not on their physical difficulties. The perspectives of well-being are core concepts of quality of life. The CP QOL-Child has already been translated in Thai and the reliability is excellent. The validity after the translation has not been conducted and is required. therefore, it is needed to examine the validity to ensure the clinical practicality.

Objective: To examine feasibility and concurrent validity of the CP QOL-Child (Thai version).

Materials and Methods: Eighty-five primary caregivers of 4- to 12-year-old children and 65 children between 9- and 12-years-old, who passed the inclusion criteria, completed three questionnaires including the CP QOL-Child (Thai version), the PedsQL 4.0 Generic Core Scales, and the PedsQL 3.0 CP module (Thai version).

Results: For feasibility of the CP QOL-Child, no missing items were found in any items for the child self-report. For parent proxy report, missing items were scattered and from 1.2% to 7.1%. For concurrent validity, according to the total scores of both versions, the self-report and the parent proxy, the correlation coefficients between CP QOL-Child and PedsQL 4.0 Generic Core Scales were 0.23 to 0.25 meaning no or little correlations, at significance level of 0.05. The correlation coefficients between the CP QOL-Child and the PedsQL CP module were 0.38 to 0.49, meaning fair correlations, at significance level of 0.01.

Conclusion: The feasibility of the CP QOL-Child (Thai version) was reportedly acceptable. The concurrent validity support that the CP QOL-Child may not measure the quality of life at the same constructs as the PedsQL. The CP QOL-Child asks the client’s perspectives of quality of life (QOL) while both PedsQL modules ask the client’s difficulties that might relate to QOL.
