The Neonatal Behavioral Assessment Scale (NBAS), also known as the Brazelton Neonatal Assessment Scale (BNAS), was developed in 1973 by T. Berry Brazelton and his colleagues. This test purports to provide an index of a newborn's abilities, and is usually given to an infant somewhere between the age of 3 days to 4 weeks old. This scale has been used widely as a research tool as well as a diagnostic tool for special purposes. Following is a list of various research projects that have implemented the Brazelton scale:

  • "Used to evaluate the effects of low birth weight on premature infants"

Further, the scores are not completely understood; further testing is required. As for validity, it has "poorly documented predictive and construct validity."

Therefore, the primary value of the test is as a research tool and a supplement test to other medical testing procedures.

Training is necessary for effective and reliable administration of the NBAS.
