Abstract

Aim: To evaluate the predictive capacity of neonatal behaviour on infant mental and psychomotor development at 4 and 12 months, and infant intelligence at 6 years.

Method: Eighty full-term newborns were followed from 3 days until 6 years. Neonatal behaviour was assessed by the Neonatal Behavior Assessment Scale (NBAS) at 3 days postpartum, infant mental and psychomotor development was assessed by the Bayley Scales for Infant Development at 4 and 12 months, and child intelligence was assessed by the Wechsler Preschool and Primary Scale of Intelligence at 6 years.

Results: Neonatal general irritability was the predictor of mental development at 12 months. Self-regulation behaviours were predictors of psychomotor development at 4 and 12 months and verbal and total intelligence quotient at 6 years. Neonatal orientation was a predictor of performance Wechsler subtests related to visomotor abilities and attention.

Conclusions: Neonatal self-regulation behaviours were the best predictors of infant development and intelligence. We suggest that the NBAS could be a useful tool to observe behaviours related to later development in healthy infants.
