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

his 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.
