The purpose of the current study was to examine how comprehensively the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) addresses Activity and Participation components of the International Classification of Functioning, Disability, and Health (ICF).


Two raters individually linked the 276 items of the PEDI-CAT to the ICF using ICF linking rules, the PEDI-CAT manual, and the ICF browser. Agreement between reviewers was evaluated, and reliability of the linking process was assessed using Cohen's ╬║.


All 9 chapters of Activity and Participation were represented within the PEDI-CAT. The highest frequency of representation was in Mobility (43%) and Self-care (20%) chapters. Agreement between the 2 raters was strong (╬║ = 0.84). Two items were not definable in the ICF, and 3 linked to Body Function codes.


The PEDI-CAT was strongly representative of the Activities and Participation component of the ICF. The linking process had substantial reliability.
