| Abstract: | The current study compared nurses', mothers', and NBAS examiners' perceptions of infant behavior along dimensions of the NBAS using the Newborn Behavior Inventory (NBI; Anderson & Standley, 1979). The hypothesis was that the three observers would differ in their perceptions based on their unique backgrounds. A total of 26 high-risk premature infants and 28 healthy full-term infants were assessed on the Brazelton Neonatal Scale (Brazelton, 1973), which provided a reference point for comparing the observers' views. Multivariate analysis of variance (MANOVA) revealed that the preterm infants obtained significantly lower scores on the cluster of autonomic regulation and on the reflex cluster. A two-way analysis of variance for repeated measures was performed to analyze the NBI data. Rater disagreement appeared on four NBAS clusters of orientation, regulation of state, range of state, and motoric processes. Agreement among observers on the autonomic cluster reflected actual group differences on the NBAS. The variability in ratings is discussed in relation to the observers' differential experience with the infants. |
