Outcome measures consisted of the performance on
Brazelton Neonatal Behavioral Assessment Scale (BNBAS).
The BNBAS is a means of scoring interactive behaviour for
term and stable preterm infants. The scale consists of 27
behavioural items, each scored on a 9-point scale, and 20
elicited responses, each scored on a 3-point scale. In most
cases, the infant’s score is based on the best performance, not
an average performance [9]
