The aims of the study were to: (1) build new item banks for a revised
version of the Pediatric Evaluation of Disability Inventory (PEDI) with four
content domains: daily activities, mobility, social/cognitive, and
responsibility; and (2) use post-hoc simulations based on the combined normative
and disability calibration samples to assess the accuracy and precision of the
PEDI computer-adaptive tests (PEDI-CAT) compared with the administration of all
items. METHOD: Parents of typically developing children (n = 2205) and parents of
children and adolescents with disabilities (n = 703) between the ages of 0 and 21
years, stratified by age and sex, participated by responding to PEDI-CAT surveys
through an existing Internet opt-in survey panel in the USA and by computer
tablets in clinical sites. RESULTS: Confirmatory factor analyses supported four
unidimensional content domains. Scores using the real data post hoc demonstrated
excellent accuracy (intraclass correlation coefficients >/= 0.95) with the full
item banks. Simulations using item parameter estimates demonstrated relatively
small bias in the 10-item and 15-item CAT versions; error was generally higher at
the scale extremes. INTERPRETATION: These results suggest the PEDI-CAT can be an
accurate and precise assessment of children's daily performance at all functional
levels.
