Influence of Modified Instructions on Locomotion Subtest Scores Using the Peabody Developmental Motor Scales, Second Edition
Pediatric Physical Therapy
Purpose: The current study assessed whether changes in verbal and visual cues used to clarify requirements of the task would result in significant score differences on the Locomotion subtest of the Peabody Developmental Motor Scales, Second Edition (PDMS-2), in children aged 2.5 to 5 years. Methods: The Locomotion subtest of the PDMS-2 was administered twice, 2 to 10 days apart, to 37 children. Age-matched and gender-matched groups received instructions in both standardized and modified formats, where order depended on group assignment. Results: Instruction type resulted in a significant change in Locomotion scores with a medium effect size and no significant interactions between instruction type and age or between instruction type and test order. Conclusions: Findings suggest instruction modifications using altered verbal and visual cues change PDMS-2 Locomotion subtest scores in children with typical development. These results support previous literature indicating that normative scores should not be reported if modifications were used during testing.
