The Bayley Scales of Infant Development-Second Edition (BSID-II) and Bayley Scales of Infant Development (BSID) were administered concurrently to 49 high-risk, preterm infants. Results suggested that scores from the two tests were correlated very highly. As expected, mean scores on the BSID-II were lower than on the BSID. Classification of infants as “normal,” “borderline,” and “abnormal” on each test resulted in excellent agreement for mental development scores, but only fair agreement for psychomotor scores. Findings were interpreted as adding support to the clinical validity of the BSID-II, and implications of lower scores on the BSID II were discussed.
