Concurrent validity of the Battelle Developmental Inventory for speech and language disordered children

Abstract

Concurrent validity of the Battelle Developmental Inventory (BDI) was investigated with speech and language disordered children between the ages of 35 and 60 months. Correlations between the BDI expressive communication subdomain and the Peabody Picture Vocabulary Test-Revised (PPVT-R), Preschool Language Scale-Revised (PLS-R), and Arizona Articulation Proficiency Scale-Revised (AAPS-R) were significant. The BDI total score was also significantly correlated with the PPVT-R and the PLS-R. There were no significant differences between the three BDI developmental quotients and PPVT-R standard scores. The receptive communication subdomain of the BDI did not correlate significantly with any of the language measures.
