WHAT IS BRAZELTON NEONATAL BEHAVIORAL ASSESSMENT SCALE TEST?
The newborn is administered the Neonatal Behavioral Assessment Scale (NBAS) multiple times in the first 10 days of life to study four levels of function of the neonate: physiologic, motor, state, and attentional/ interactional. Function is determined by an assessment of the response to 28 behavioural items with 7 supplementary items, all scored on a 9-point scale, and 18 reflex items, scored on a 4-point scale. The hypothesis is that a newborn’s behaviour is dependent on not only genetics but also intrauterine nutrition, infection, drug abuse, and perinatal events. All these factors contribute to a child’s temperament and may explain why different babies respond to touch, sound, or visual stimuli in different ways. Once the child has been assessed, Brazelton believes that recommendations can be made how best to interact with that child by describing the behavioural strengths and weaknesses.
