Reliability of the modified Paediatric Evaluation of Disability Inventory, Dutch version (PEDI-NL) for children with cerebral palsy and cerebral visual impairment


Purpose: The aims of this study were to adapt the Paediatric Evaluation of Disability Inventory,Dutchversion(PEDI-NL)forchildrenwithcerebralvisualimpairment(CVI)and cerebralpalsy(CP)anddeterminetest–retestandinter-respondentreliability.

Method: The Delphi method was used to gain consensus among twenty-one health experts familiar with CVI.Test–retestandinter-respondent reliabilitywereassessedfor parents and caregivers of 75 children (aged50–144months ) with CP and CVI. The percentage identical scores of item scores were computed, as well as the interclass coefficients(ICC)and Cronbach’s alphas of scale scores over the domains self-care, mobility, and social function.

Results: All experts agreed on the adaptation of the PEDI-NL for children withCVI.On item score, for the Functiona lSkills scale,mean percentage identical scores variations for test– retest reliabilitywere73–79 with Caregiver Assistance scale 73–81, and for inter- respondent reliability 21–76 with Care giver Assistance scale 40–43.For all scales overall domains ICCs exceeded 0.87. For the domains self-care, mobility, and social function, the Functional Skills scale and the Caregiver Assistance scale have Cronbach’s alpha above 0.88.

Conclusion: The adapted PEDI-NL for children with CP and CVI is reliable and comparable to the original PEDI-NL.
