Title: Reliability of the Peabody Developmental Gross Motor Scale in Children with Cerebral Palsy
Abstract: The test/retest, intrarater, and interrater reliability of the Peabody Development Gross Motor Scale (PDGMS) was assessed in 12 children with mild or moderate cerebral palsy. A baseline test was administered, scored, and videotaped by one rater and rescored from the videotape by a second independent rater. In order to minimize the effect of developmental maturation, test/retest correlation coefficients of the tests were performed two weeks apart. The intraclass correlation coefficients ranged from 0.82 to 0.98. For interrater reliability, testing following the same protocol was repeated at 2 weeks, 3 and 6 months. Interrater correlation coefficients (r) ranged from 0.89 to 0.98. Interrater correlation coefficients (ICC) from scoring and later rescoring ten videotapes with the closest and furthest interrater agreement ranged from 0.88 to 0.99. The balance and locomotor skill categories were most responsive for assessing gross motor function in this population. These data support the use of the PDGMS as an assessment tool for children with cerebral palsy and the reliability of videotaping assessments.
