A multivariate study of the effects of high-risk factors on performance on the Brazelton Neonatal Assessment Scale.

The Brazelton Neonatal Assessment Scale was administered to 52 newborn infants. A factor analysis revealed 2 main factors, 1 along an attention-orientation dimension, the other relating to temperament arousal. A stepwise multiple linear regression analysis showed that the attention-orientation factor was related to birth weight, age of the mother, and sex and race of the baby. The only variable related to the temperament-arousal factor was 5-min Apgar scor. The study, although exploratory, demonstrates the use of multivariate techniques in the assessment of influences on newborn behavior.

对52名新生儿实施了布雷泽尔顿新生儿评估量表。因素分析揭示了两个主要因素，一个是注意力 - 定向维度，另一个与气质唤起有关。逐步多元线性回归分析表明，注意力 - 定向因素与出生体重、母亲年龄以及婴儿的性别和种族有关。与气质 - 唤起因素相关的唯一变量是5分钟阿普加评分。这项研究虽然是探索性的，但展示了多变量技术在评估对新生儿行为影响方面的应用。
