Infant Development as Measured by Bayley Scales at Week 52 and Week 104
Časové okno: At Week 52 and 104

The Bayley Scales of Infant and Toddler Development include a set of individually administered developmental scales designed to measure current developmental functioning in infants and toddlers up to 42 months of age in the areas of cognition, language, motor skills, social-emotional, and adaptive behavior, with age adjusted for prematurity. The cognition, language, motor skills scales are directly administered to the infant, while social-emotional, and adaptive behavior scales are caregiver questionnaires. The scores are standardized using norm reference samples with representative demographics and age adjusted for prematurity. |
