The concordance between foster mothers' attachment state of mind and foster infants' attachment quality was examined for 50 foster mother-infant dyads. Babies had been placed into the care of their foster mothers between birth and 20 months of age. Attachment quality was assessed between 12 and 24 months of age, at least 3 months after the infants' placement into foster care. The two-way correspondence between maternal state of mind and infant attachment quality was 72%, kappa = .43, similar to the level seen among biologically intact mother-infant dyads. Contrary to expectations, age at placement was not related to attachment quality. Rather, concordance between maternal state of mind and infant attachment was seen for relatively late-placed babies, as well as early placed babies. These findings have two major implications. First, following a disruption in care during the first year and a half of life, babies appear capable of organizing their behavior around the availability of new caregivers. Second, these data argue for a nongenetic mechanism for the intergenerational transmission of attachment.
对50对寄养母婴进行了研究，以考察寄养母亲的依恋心理状态与寄养婴儿的依恋质量之间的一致性。婴儿在出生至20个月大期间被安置到寄养母亲的照料之下。依恋质量在婴儿12至24个月大时进行评估，此时距离婴儿被安置到寄养家庭至少已有3个月。母亲心理状态与婴儿依恋质量之间的双向对应率为72%，kappa值为0.43，这与亲生母婴对中观察到的水平相似。与预期相反，安置时的年龄与依恋质量无关。相反，无论是安置较晚的婴儿还是较早安置的婴儿，都出现了母亲心理状态与婴儿依恋之间的一致性。这些发现有两个主要意义。第一，在生命的前一年半中照料关系中断后，婴儿似乎有能力围绕新照料者的可得性来组织自己的行为。第二，这些数据支持了依恋代际传递的非遗传机制。
