Predictive validity of the Bayley, Third Edition at 2 years for intelligence quotient at 4 years in preterm infants.
To determine the predictive validity of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) at age 2 years for cognitive abilities in preschool children born at ≤ 30 weeks' gestation. ⋯ In contrast with previous editions of the BSID, the Bayley-III has strong predictive validity for WPPSI-III IQ at age 4 years in preterm children. This has important implications for more timely evaluation of perinatal interventions, establishment of guidelines for neonatal care, and counseling parents.
