Abstract

PURPOSE:

To examine concurrent validity, item-specific reliability, and score distributions of the new Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) Mobility domain with the original PEDI Functional Skills (FS) Mobility Scale.

METHODS:

Thirty-five parents of children with neurodevelopmental disabilities completed the PEDI-CAT on a computer and the paper PEDI FS via interview.

RESULTS:

Strength of association between the PEDI-CAT Mobility domain and PEDI FS Mobility Scale scores was good to excellent (r = 0.82; P < .001). Intraclass correlation coefficients ranged from .3390 to 1.000, and agreement ranged from 60% to 100% for 8 specific items. No child had the minimum score on either test, whereas 9 children (26%) had a maximum score on the PEDI FS Mobility Scale.

CONCLUSIONS:

This study provides evidence for potential users that the concurrent validity, reliability, and score distribution for the PEDI-CAT Mobility domain are adequate for use with children with varied diagnoses and throughout the pediatric age span.
