Anderson PJ, De Luca CR, Hutchinson E, Roberts G, Doyle LW, and the Victorian Infant Collaborative Group. Underestimation of developmental delay by the new Bayley-III scale. Arch Pediatr Adolesc Med 2010;164:352-6.Question Among 2-year-old children who were extremely preterm and those carried to term, can the Bayley Scales of Infant and Toddler Development (Bayley-III) accurately detect developmental delay?Design Prospective cohort study. Setting The state of Victoria, Australia.Participants Consecutive surviving children (n = 221) who were born either at less than 28 weeks' gestational age (extremely preterm [EP]) or with less than 1000 g birth weight (extremely low birth weight [ELBW]) in the state of Victoria, Australia, in 2005 and randomly selected controls (n = 220) who were both carried to term and of normal birth weight.Intervention Development was assessed in survivors at 2 years of age, corrected for prematurity, using the Bayley-III scale. Children were also assessed for neurosensory impairments by blinded pediatricians.
