A study of the development of the Korean version of PedsQLTM 3.0cerebral palsy module and reliability and validity

摘要

[Purpose] The purpose of this study was to develop the Korean version of the PedsQL^TM 3.0 Cerebral Palsy Module to evaluate the health-related quality of life of children with cerebral palsy and to test the reliability and validity. [Subjects and Methods] The study included 108 caregivers of children with cerebral palsy aged 2 to 4 years and 72 caregivers of children aged 5 to 7 years, who visited multiple sites between February and August 2015. The Translation Commission performed the first translation with the approval of the Mapi Research Trust Company to create a Korean-version of the PedsQL^TM. Afterwards, back-translation was performed by one translator specializing in health and medical treatment who was a native English-speaker fluent in Korean, and one native Korean-speaker fluent in English. The consistency of each question was confirmed and a translation-integrated version was created. Test components were explained to caregivers during a one-on-one interview; caregivers then completed the PedsQL^TM questionnaire and a Pediatric Evaluation Disability Inventory (PEDI) questionnaire. Subjects contributing to test-retest measures were asked to repeat the PedsQL questionnaire one week later and return it by mail. To assess data quality for the survey question results, non-response rate, ceiling effect, and floor effect were analyzed. Test-retest reliability and internal consistencyreliability were assessed. For test-retest reliability, an intraclass correlationcoefficient (ICC) was calculated, and for internal consistency reliability, Cronbach’salpha was used. To test criterion-related validity, Pearson’s correlation coefficient wasused. [Results] The content validity of the PedsQL 3.0 Cerebral Palsy Module was high forboth age groups, and demonstrated significant internal consistency (>0.7) in all areas.For test-retest reliability, both groups demonstrated a significant ICC (>0.61).Correlation with the PEDI was statistically significant in all areas except pain and hurt.[Conclusion] The Korean version of the PedsQL^TM 3.0 Cerebral Palsy Module wasfound to be reliable and valid, and is expected to contribute greatly to the evaluation ofthe quality of life of children with cerebral palsy.
