Concurrent validity of the early intervention developmental profile and the peabody developmental motor scale-2.

摘要

PURPOSE:: The purpose of this study was to determine the concurrent validity of the Early Intervention Developmental Profile (EIDP) and the Peabody Developmental Motor Scale-2 (PDMS-2) in examining gross motor delay. METHODS:: Thirty children with a variety of developmental delays attending an early intervention program were administered both the PDMS-2 and the EIDP as part of their developmental evaluations. RESULTS:: The PDMS-2 and EIDP were strongly correlated (r = 0.91, p < 0.01) but the mean age equivalent scores were significantly different. Age equivalent scores were on average 26% higher on the EIDP. CONCLUSIONS:: Differences in age equivalent scores between tests may affect a child's eligibility for services in some states. This study supports the use of norm-based tests when determining a percentage of delay relative to the norm. Developmental tests should not be the sole determinant of the clinical decision making processes.
