title: Comparison of Vineland Adaptive Behavior Scales-Survey Form age equivalent and standard score with the Bayley Mental Development Index.
abstract: The Vineland Adaptive Behavior Scales-Survey Form standard score, Vineland Adaptive Behavior Scales-Survey Form age equivalent and Bayley scales' Mental Development Index were given to 44 high-risk infants age 12 mo. and suspected of developmental delay. The VABS-Survey Form, a revision of the Vineland Social Maturity Scale is frequently used in assessment of developmental delay; however, questions have arisen as to whether the standard score or age equivalent is the better measure. A developmental quotient based on VABS-SF age equivalent and VABS-SF standard score was compared with the Bayley Mental Development Index. The mean VABS-SF standard score was significantly higher than the age equivalent quotient and the Bayley Mental Development Index. Implications for the use of VABS-SF age equivalent in evaluating such infants are discussed.
