Abstract

The aim of this study was to see whether the scores of the Bayley Infant Neurodevelopmental Screener of 45 high-risk preterm infants (gestational age 26-37 wk) between the ages of 3 and 24 months predicted neurodevelopmental status at 7 to 10 years of age. Neurodevelopmental status of 45/122 preterm infants, grouped according to their gestational ages of 26 to 29, 30 to 32, and 33 to 37 weeks, were previously evaluated by Bayley Infant Neurodevelopmental Screener. The scores were categorized as low or high-moderate. Verbal and performance scores of Wechsler Intelligence Scale for Children-Revised (WISC-R) of those patients were assessed between 7 and 10 years. The patients with high-moderate-risk scores of Bayley Infant Neurodevelopmental Screener at all times, regardless of their gestational age, had lower performance, verbal, and total scores of WISC-R than those of who had low Bayley Infant Neurodevelopmental Screener risk scores. High-moderate risk score of Bayley Infant Neurodevelopmental Screener at 7 to 10, and 16 to 20 months, of all patients especially showed good prediction for identifying lower verbal and performance scales. For 7 to 10 months, verbal scale: positive predictive value = 92.3%, negative predictive value = 44.4%, sensitivity = 70.58%, and specificity = 80%; performance scale: positive predictive value = 100%, negative predictive value = 30%, sensitivity = 68.18%, and specificity = 100%. For 16 to 20 months, verbal scale: positive predictive value = 90%, negative predictive value = 37.5%, sensitivity = 64.3%, and specificity = 80%; performance scale: positive predictive value = 90%, negative predictive value = 12.5%, sensitivity = 56.3%, and specificity = 50%. Bayley Infant Neurodevelopmental Screener shows good prediction of later verbal and performance scores of Wechsler Intelligence Scale-Revised for Children as early as 7 to 10 months, which gives us the opportunity to start early intervention.
