The PEDI-CAT provides two types of scores calculated for each of the four domains:
- Normative scores (provided as age percentiles and T scores)-based on a child’s chronological age and intended for use by clinicians so that they may interpret a particular child’s functioning relative to others of the same age.
- Scaled scores provide a way to look at a child’s current functional skills and progress in these skills over time. Scaled scores are especially helpful in documenting improvements in functional skills for children not expected to exhibit or regain normative levels of functioning.
- Item Maps–represent a reasonable, sequential pattern of functional skills consistent with children’s development and recovery of function and transfer of responsibility from adult to child throughout childhood and young adulthood. For an example of an item map, click here.
Linking Original PEDI Scores to PEDI-CAT Scores
Equations have been developed and are available in the PEDI-CAT manual to link previous Functional Skills Self-care, Mobility and Social Function scores from the original PEDI to the PEDI-CAT so that clinicians may continue to track a child’s changes over time. Of note, there is no conversion for the Caregiver Assistance Scale as it has been replaced with the Responsibility Domain.
Development and Standardization of the PEDI-CAT
The PEDI-CAT’s normative standardization sample was recruited through an online panel and resulted in a nationally representative sample of 2,205 parents of children less than 21 years of age in the contiguous United States.
The clinical validation sample of 703 children with disabilities (behavioral, intellectual and physical) was also recruited through the online panel as well as through two clinical sites in the Northwest Central and Northeastern United States.
