Purpose: Assessment of functional health and health related quality of life (HRQL) of children with cerebral palsy (CP) are important for effective rehabilitation practices. Therefore, the present study was aimed to provide a Turkish version of PODCI which is one of the prevalently used HRQL scales in CP, to investigate reliability and validity of the scale for children with CP. Methods: Age range was between 2 and 18 years, 105 children with CP, 48 healthy children and their mothers were recruited for the study subjects were divided into three age groups, i.e. 2-7, 8-12, and 13-18. GMFCS levels, clinical types, demographical and socio-economical data of the cases with CP, PODCI scores and also PedsQL and CHQ PF-50 scores as a gold standard, of participants were recorded. Results: Findings of the reliability of PODCI showed that the internal consistency was acceptable and test-retest reliability was quite high (Alpha=0.93, ICC=0.992). Findings of the validity of the scale indicated that it was highly sensitive in separating children with CP from healthy children (p<0.001). The scale could differ age groups, clinical types and GMFCS groups only in the physical functioning domain (p<0.05). The correlations among subscales of three scales illustrated that the convergent validity was established while divergent validity was low. Conclusion: Turkish version of PODCI is reliable and valid for assessing functional health and HRQL of children with CP.
