The Neonatal Behavioral Assessment Scale
(NBAS) was developed in 1973
by Dr. T. Berry Brazelton
and his colleagues. It evaluates a wide range of 38 behaviors to build a behavioral profile of an infant up to two months old. This approach was innovative for recognising that a baby is a highly developed organism, even when just newly born. The profile describes the baby's strengths, adaptive responses and possible vulnerabilities, and may help parents to develop appropriate caregiving strategies to enhance their earliest relationship with the child.
Training is necessary for effective and reliable administration of the NBAS.
