Reliability and validity of a chinese version of the pediatric evaluation of disability inventory in children with cerebral palsy
OBJECTIVES: To examine the reliability and validity of a Chinese version of the Pediatric Evaluation of Disability Inventory in children with cerebral palsy.
DESIGN: A prospective study.
SUBJECTS: Two samples: 58 children with cerebral palsy (mean age 65.4 (standard deviation 29.9) months) and 89 normally developing children (mean age 43.5 (standard deviation 20.6) months).
METHODS: The Pediatric Evaluation of Disability Inventory was translated and cross-culturally adapted into a Chinese version. The test-retest reliability, concurrent validity and discriminative validity were examined.
RESULTS: Internal consistency was high (Cronbach’s α: 0.90–0.99). Test-retest reliability was excellent (intraclass correlation coefficient: 0.982–0.998). The concurrent validity was good, as evidenced by the high correlation between the Pedia¬tric Evaluation of Disability Inventory and the Functional Independence Measure for Children (Spearman’s ρ: 0.92–0.99). Logistic regression analysis demonstrated that the Pediatric Evaluation of Disability Inventory factor scores estimated by confirmatory factor analysis differentiated the children with cerebral palsy from normally developing children.
CONCLUSION: This study demonstrated that the Chinese version of the Pediatric Evaluation of Disability Inventory has good reliability and validity and provides support for its use in Chinese-speaking children with cerebral palsy.
