Research Report

Purpose: The purpose of this study was to compare the Pediatric Evaluation of Disability Inventory (PEDI) and the Mullen Scales of Early Learning (MSEL) as measures of change in children who received early intervention services.

Methods: Thirty-four children were stratified into 2 groups according to the presence of gross motor delay. The PEDI and MSEL were administered 3 times: at an average age of 18, 31, and 53 months of age. Data were analyzed using a repeated-measures multivariate analysis of variance.

Results: The findings suggest that PEDI Functional Skills Scaled Scores were capable of measuring change in both groups of children. The standard scores on the PEDI Functional Skills Social Scale were found to be more sensitive to change than the MSEL Receptive and Expressive Language scores for children with motor delays.

Conclusion: Using PEDI scaled scores may be an effective strategy for measuring change in children receiving early intervention services.

The authors found in a study of the sensitivity of the PEDI that it would be an effective measure of change in children who are receiving EI services and between the ages of 15 and 53 months.
