Neurodevelopmental outcome of Italian preterm children at 1 year of corrected age by Bayley-III scales: an assessment using local norms
Background: Premature birth is often associated with neurodevelopmental difficulties throughout childhood. In
the first three years of life, the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III)
constitute one of the most used tools for assessing child development. Since Bayley-III original norms are based
on United States (US) population, it remains uncertain whether their use in other countries (e.g., European) is
appropriate.
