Clinical Validity of Bayley-4: Comparison of Clinical Groups & Matched Controls

A primary purpose of the Bayley-4 is to identify infants and toddlers who have delays in development.  One way to verify the validity of the new test for this purpose is to compare children from at-risk groups to matched controls to determine if there are differences in scores. Infants and toddlers from specifically defined risk groups were included in the Bayley-4 validity studies (for example: children with Autism Spectrum Disorder; Language Delay; Developmental Delay; Motor Impairment; Prenatal Drug/Alcohol Exposure; Moderately or Late Preterm (32-36 weeks); and Extremely or Very Preterm (<32 weeks)).  Children from these risk groups were compared on all the Bayley-4 subscales.
