Abstract: Objective To investigate the reliability of Pediatric Evaluation of Disability Inventory (PEDI) in China. Methods 21 children with cerebral palsy were assessed with PEDI by 2 raters respectively. The intrarater and interrater agreement was analyzed. The internal consistency of the PEDI was also calculated. Results The ICC of intrarater and interrater was 0.919～0.993. The Cronbach α was 0.9597～0.9711 in self care, 0.9569～0.9799 in mobility, 0.9419～0.9830 in social function.Conclusion PEDI is reliable and internal consistent.

Key words: Pediatric Evaluation of Disability Inventory (PEDI), reliability, cerebral palsy, assessment
