The purpose of this research was to provide physical and occupational therapists with empirical data and clinical information that will enable them to better understand and utilize the Peabody Developmental Motor Scales (PDMS) in the assessment of children who potentially may need physical and/or occupational therapy. The PDMS was administered to 20 developmentally delayed children between the ages of 24 and 83 months, who were receiving both physical and occupational therapy in the Chesapeake Public School System. The PDMS was also administered to 20 normal subjects between the ages of 24 and 77 months that were volunteers from the PTA and the staff of the Chesapeake Public School System. Interrater reliability was .78 for gross-motor item scores, .99 for gross-motor total scores, .67 for fine-motor item scores, and .99 for fine-motor total scores. Correlation coefficients are given for the comparison of gross-motor and fine-motor skill and total scores. A one-tailed t-test indicated a significant difference at the level of .01 between the two groups. Based on these results, the Peabody Developmental Motor Scales provide reliable data based on norms, but has limitations in qualitative implications in the assessment of developmentally delayed children.
