A Pilot Validation Study of the Newborn Behavioral Observations System: Associations with Salivary Cortisol and Temperament.

ABSTRACT:

Objective

There are few standardized neonatal neurobehavioral instruments available for longitudinal child development research. We adapted an established clinical tool, the Newborn Behavioral Observations (NBO) system, for research by standardizing the administration protocol and expanding the 3-point coding scale to 5 points.

Methods

We administered the 5-point NBO to 144 racially/ethnically diverse late preterm or term infants born to low-income women (average age 5 weeks). Cronbach's alphas were calculated to determine internal consistency reliability of Autonomic, Motor, Organization of State, and Responsivity subscales. We examined concurrent validity using subscale associations with infant salivary cortisol reactivity to the NBO and maternally reported infant temperam
