Comparison between speedy and content-balanced versions of the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) in children with cerebral palsy

ABSTRACT This study aimed to compare the speedy and content-balanced versions of the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT) in its four domains. A cross-sectional observational study was conducted with children with cerebral palsy (CP). The two versions of PEDI-CAT were administered to each child with a 7-days interval, remotely, in interview format with caregivers. Pearson’s correlation was used to evaluate the association among scaled scores in the two versions of PEDI-CAT. In total, 11 children with CP, aged 2 to 12 years, participated in the study. A strong significant association between mean values of the scaled score of the speedy and content-balanced versions in all domains (p<0.0001) was observed. Two children (18.2%) were classified differently regarding normative standard score in the Social/Cognitive domain. Both versions of PEDI-CAT showed concordant results in relation to the scaled score when applied to children with CP. However, one must cautiously interpret the normative standard score depending on the version used in the Social/Cognitive domain.
