Abstract

Abstract: Background: Although several studies have investigated the association between Bayley‐III results in infancy and future intellectual development, conclusions remain unclear. We used the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley‐III) at 3 years of age and the Wechsler Intelligence Scale for Children, Fourth Edition (WISC‐IV) at 6 years of age to assess the neurodevelopment of very low birthweight infants. Methods: We investigated the correlation between Bayley‐III's cognitive, language, and motor scores and the WISC‐IV's Full‐Scale Intelligence Quotient (FSIQ). We also determined the optimal cut‐off value of Bayley‐III to enter the normal development zone (FSIQ ≥ 85). Results: We found a strong correlation between the Bayley‐III and the FSIQ. Optimal cut‐off scores of the Bayley‐III to enter the normal range on the WISC‐IV were 95 for the cognitive scale, 89 for the language scale, and 91 for the motor development scale. Conclusions: Although Bayley‐III scores strongly correlated with the WISC‐IV FSIQ, the lower normal limit of 85 on the Bayley‐III suggests a potential overestimation of development in children who were VLBW infants.
