将 160 名稳定的早产双胞胎的行为评估分数与 120 名足月新生儿双胞胎的行为评估分数进行了比较。在各种活动中对双胞胎进行检查，以获得以下行为类别的代表性行为样本：烦躁、对安抚的抵抗、反应性、强化值和活动水平。在所有行为类别中都发现了配对内相关性，表明体质对新生儿时期的行为模式有影响。早产儿在前三类中表现出与足月组相似的内部行为一致性。然而，在比较早产儿和足月儿对项目的实际评分时，发现了组间差异。这些足月双胞胎和早产双胞胎之间的行为差异与已发表的单胎婴儿样本的差异相当。
Scores from a behavioral assessment of 160 stable preterm newborn twins were compared with those obtained from 120 full-term newborn twins. The twins were examined during various activities to obtain representative samples of behavior in the following behavioral categories: irritability, resistance to soothing, reactivity, reinforcement value, and activity level. Within-pair correlations were found in all of the behavioral categories, suggesting a constitutional influence on behavioral patterns during the neonatal period. The preterm infants demonstrated internal consistency of behavior similar to that of the full-term group in the first three categories. However, group differences were found when comparing the preterm with the full-term infants on actual ratings of the items. Behavioral differences between these full-term and preterm twins were comparable to those published for samples of singleton infants.
