BACKGROUND AND PURPOSE: The purpose of this study was to examine the validity of the Peabody Developmental Gross Motor Scale ( @entity7419 ) as an evaluative measure of @entity1 receiving physical therapy. SUBJECTS AND METHODS: @entity1 who attended an early intervention program (N = 124) were grouped by diagnosis: @entity306 , @entity1467 , @entity1276 , preterm with @entity245 , full term with @entity245 , and other. The @entity7419 was administered to each @entity1 three times over a 6-month period by a therapist who did not provide treatment. RESULTS: Mean scaled scores and age-equivalent scores increased for each group. Individual change was examined using the reliable change index. The results indicated that the change in total raw score for 62% of the @entity1 was greater than what could be attributed to measurement error. When minimal clinically important change was defined as 10 scaled score points, the index of responsiveness was equal to 0.5. This finding indicates that a sample size of 68 subjects per group would be needed when the @entity7419 is used as an outcome measure in research. CONCLUSION AND DISCUSSION: The mean change scores for each group support the use of the @entity7419 as an evaluative measure. For many @entity1 , particularly @entity1 with @entity306 , the @entity7419 was not responsive to change over a 6-month period. The index of responsiveness suggests that the @entity7419 should be used only as an outcome measure in large clinical trials. The @entity7419 is not recommended for evaluating the direct effects of physical therapy but is recommended for providing a global measure of change in motor development as part of a multidimensional assessment.
