Concurrent Validity of the Battelle Developmental Inventory: Relationship with the Bayley Scales in Young Children with Known or Suspected Disabilities

Abstract
The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in infants with known or suspected disabilities. Both the pattern and the strength of the obtained correlations lend support to the Battelle as an appropriate measure of development in infants with handicaps. Salient characteristics of the two measures are compared to aid practitioners in making an intelligent choice between these two instruments.
