To assess the combined risks of being born preterm and to a teenage mother, and to evaluate the effects of an early intervention, preterm infants born to lower-class, black, teenage mothers were provided a home-based, parent-training intervention, and their development was then compared with that of nonintervention controls, of term infants of teenage mothers, and of term and preterm infants of adult mothers. Despite equivalence on prenatal care, factors which placed the preterm infant of the teenage mother at greater risk at birth were the small-for-date size of the infant and the less realistic developmental milestones and child rearing attitudes expressed by the mother. The preterm infants of teenage mothers who received intervention showed more optimal growth, Denver scores, and face-to-face interactions at 4 months. Their mothers rated their infants' temperaments more optimally, expressed more realistic developmental milestones and child-rearing attitudes, and received higher ratings on face-to-face interactions. At 8 months, the intervention group received superior Bayley mental, Caldwell, and infant temperament scores.
为评估早产及母亲为青少年所带来的综合风险，并评估早期干预的效果，对出生于下层社会、黑人、青少年母亲的早产婴儿提供了一项基于家庭的家长培训干预措施，然后将他们的发育情况与未干预的对照组、青少年母亲所生足月儿以及成年母亲所生足月儿和早产儿进行比较。尽管在产前护理方面相当，但使青少年母亲所生早产儿在出生时面临更大风险的因素包括婴儿小于胎龄、母亲所表达的发育里程碑和育儿态度不太现实。接受干预的青少年母亲所生早产儿在4个月时表现出更优的生长、丹佛发育筛查量表得分以及面对面互动。她们的母亲对婴儿气质的评价更优，表达了更现实的发育里程碑和育儿态度，并且在面对面互动方面获得了更高的评价。在8个月时，干预组在贝利智力发育量表、考德威尔家庭环境量表及婴儿气质得分方面表现更优。
