The Pediatric Evaluation of Disability Inventory (PEDI)

The Pediatric Evaluation of Disability Inventory (PEDI; Haley, Coster, Ludlow, Haltiwanger, & Andrellos, 1992) is a judgment-based questionnaire that evaluates functional skills in the domains of self-care, mobility, and social function for children ages 6 months to 7 years old.


Using a 0 or 1 scale, the caregiver rates whether the child is capable of or unable to perform each item. The PEDI also includes questions about the amount of caregiver assistance and environmental modifications needed for certain tasks.

The inventory is designed for use as a structured interview; when used in its entirety, it takes 45 to 60 minutes to administer. It can also be administered as separate components, as normative scores are available for each of the three domains. The PEDI is a norm-referenced measure that also contains a criterion-referenced component. For children outside of the age range of the PEDI to whom standard scores do not apply, the score may be looked at on a continuum from low- to high-functioning.
