An Investigation of the Validity and Reliability of the Battelle Developmental Inventory with a Population of Children Younger than 30 Months with Identified Handicapping Conditions

Abstract

Little information is available on the use of the Battelle Developmental Inventory (BDI) with children under 30 months of age who have identified handicaps. In this study, the BDI, Bayley Scales, and Vineland Scales of Adaptive Behavior—Survey Form were administered to 40 children. Results indicated high concurrent validity, interrater reliability, and internal consistency for the BDI. The use of the BDI with this population is discussed.
