Content Validity and Reliability of the Brief International Classification of Functioning, Disability and Health Core Sets for Children and Youth with Cerebral Palsy
Keywords:

Background and Objective: The brief ICF core sets for children and youth (CY) with cerebral palsy (CP) is a tool that needs to be validated for assessment in people with cerebral palsy to ensure its appropriate application in the cultural, social and economic context of Thailand. Therefore, the purpose of this study was to test the content validity and reliability of the brief ICF core sets for CY with CP.
Methods: The brief ICF core sets for CY with CP in the version of English language was changed into a Thai version, 42 codes total, based on the Thai language-translated ICF. The brief ICF core sets for CY with CP in the Thai language version were considered the item content validity by five pediatric physical therapists. Ten pediatric physiotherapists were invited to test the intra- and inter-rater reliability of this tool with video clips watching the ICF assessment in 24 children and youth with CP and scoring using a Google form. Data were analyzed using intraclass correlation coefficients (ICCs).
Results: The content validity index can be acceptable the 38 codes (90%) out of 42 codes. The ICCs of intra-rater and inter-rater reliability were a value between 0.69 to 1.00 (p< 0.05) and 0.62 to 1.00 (p< 0.05), respectively.
Conclusion: This study showed that brief ICF core sets for CY with CP (Thai language) had acceptable content validity and between moderate to very good reliability. However, a feasibility study should test such face validity before application in practice.
