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.
使用贝利婴儿行为记录（IBR）对3组高危新生儿及其对照组在孕龄92周时进行了评估。3组高危婴儿分别是出生体重1500克及以下且无需呼吸机治疗的婴儿、出生体重1500克及以下且需要呼吸机治疗的婴儿，以及出生体重超过1500克且需要呼吸机治疗的新生儿。对照组是在7个社会经济和人口统计学变量上匹配的健康足月儿。3组高危婴儿和对照组的IBR评分的第一主成分相似。所有3组高危婴儿在大多数项目上的IBR评分都不如其对照组。此外，高危组之间也存在一些差异；无论出生体重如何，使用呼吸机的婴儿在IBR总体表现上的评分最低，极低出生体重且使用呼吸机的新生儿更有可能获得表明婴儿过度活跃且注意力持续时间短的评分，而极低出生体重且从未使用呼吸机的婴儿最有可能被评为快乐但被动且发育迟缓。高危婴儿与对照组之间的差异在很大程度上是由在智力和运动发育方面也延迟的婴儿导致的。
