Linking the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) to the International...

Area of Science:

• Rehabilitation Medicine
• Disability Studies
• Health Informatics

Background:

• The International Classification of Functioning, Disability, and Health (ICF) provides a standardized framework for describing health and functioning.
• The Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT) is a widely used tool for assessing childhood disability.
• Evaluating the alignment of assessment tools with the ICF is crucial for consistent data interpretation and cross-cultural comparisons.

Purpose of the Study:

• To assess the comprehensiveness of the PEDI-CAT in representing the Activity and Participation components of the ICF.
• To determine the extent to which PEDI-CAT items map to specific ICF categories.

Main Methods:

• Two independent raters linked all 276 PEDI-CAT items to the ICF using established linking rules, the PEDI-CAT manual, and the ICF browser.
• Inter-rater reliability was quantified using Cohen's kappa (κ).

Main Results:

• All nine ICF chapters for Activity and Participation were represented in the PEDI-CAT.
• Mobility (43%) and Self-care (20%) showed the highest item representation.
• Strong agreement between raters was observed (κ = 0.84), with only 5 items having definitional or linking discrepancies.

Conclusions:

• The PEDI-CAT demonstrates strong representativeness of the ICF's Activity and Participation components.
• The item-linking process exhibited substantial reliability, supporting the PEDI-CAT's utility in a standardized functional assessment context.
