Introduction[edit | edit source]

The first 3 years of life in a child's life are described as a "key period of physical, physiological, cognitive and social development" by Barlow et al (2018)[1] The Neonatal Behavioral Assessment Scale (NBAS) is a neurobehavioral assessment. It is a tool used to describe an infant's interaction with their extrauterine environment. Furthermore, it highlights the emerging relationship between caregiver and infant, ultimately presenting a holistic picture of clinical conditions of both term and preterm infants. [2][3]

Constructed by Brazelton in 1973, the NBAS underwent revision in 1984 and 1995. In 2000 the Newborn Behavioural Observation System (NBO) was constructed as a new flexible shortform version of the NBAS.[2]

Objective[edit | edit source]

Assesses:

  • An infants behavioural repertoire.[4]
  • The competencies in both healthy and at-risk infants.[3]

The NBAS is used in the identification of prenatal and neonatal factors which influence development and behaviour. [3]

With a series of examinations, the NBAS allows those examining to observe the integration of discrete behaviours of the infant into coherent patterns of behaviour and development.[4]

The NBAS has also been increasingly used as an intervention tool, to improve the sensitivity and quality of the caregiver-infant relationship. This includes improving the bonding relationship of caregivers and infants born blind, infants with Down Syndrome and infants born into low socioeconomic status[3]

Intended Population[edit | edit source]

The intended population for the NBAS is from birth up to 2 weeks after birth.[4]

It can be used in term and preterm infants.
