Differences on Bayley's infant behavior record for a sample of high-risk infants and their controls
Insights
High-risk newborns, including those requiring ventilator therapy, showed less favorable behavioral development at 92 weeks. Ventilated infants and very low birth weight infants exhibited distinct behavioral patterns compared to controls.
Area of Science:
- Neonatalogy
- Developmental Pediatrics
- Behavioral Science
Background:
- High-risk newborns face developmental challenges.
- Early behavioral assessment is crucial for identifying at-risk infants.
Purpose of the Study:
- To compare the behavioral development of different high-risk newborn groups with healthy controls.
- To identify specific behavioral patterns associated with prematurity and ventilator use.
Main Methods:
- Utilized Bayley's Infant Behavioral Record (IBR) at 92 weeks post-conceptional age.
- Compared three high-risk newborn groups (low birth weight/no ventilator, low birth weight/ventilator, high birth weight/ventilator) with matched healthy term controls.
Main Results:
- All high-risk groups received lower IBR ratings than controls.
- Ventilated infants had the poorest overall performance.
- Very low birth weight, ventilated infants were rated as hyperactive with short attention spans.
- Very low birth weight, non-ventilated infants were rated as happy but passive and delayed.
Conclusions:
- High-risk newborns exhibit significant behavioral differences compared to healthy peers.
- Ventilator therapy and very low birth weight are associated with specific, less desirable behavioral outcomes.
- Developmental delays contribute significantly to the observed behavioral differences in high-risk infants.
Abstract:
3 groups of high-risk newborns and their controls were assessed at 92 weeks post-conceptional age using Bayley's Infant Behavioral Record (IBR). The 3 groups of high-risk infants were those who weighed 1,500 grams or less at birth and required no ventilator therapy, those weighing 1,500 grams or less at birth who required ventilator therapy, and newborns weighing more than 1,500 grams at birth who required ventilator therapy. Controls were healthy term infants matched for 7 socioeconomic and demographic variables. The first principal component of the IBR ratings for the 3 groups of high-risk infants and the controls were similar. All 3 groups of high-risk infants received less desirable IBR ratings on most items than their controls. In addition, there were some differences among high-risk groups; ventilated infants regardless of birth weight received the lowest ratings reflecting overall performance on the IBR, very low birthweight, ventilated newborns were more likely to receive ratings characterizing an overly active infant with a short attention span, and very low birth-weight, never-ventilated infants were most likely to be rated as happy but passive and delayed. The differences between the high-risk infants and controls in large part resulted from infants who were also delayed in terms of their mental and motor development.
