Studies of adult outcomes of infant domestic adoptions are considered: the range of psychological and behavioural outcomes recorded, the current state of knowledge summarised and the importance of the chosen comparison groups discussed. The social context of infant adoptions is described. Findings from our follow-ups of British infant adoptions in the post-World War 11 period are then briefly reported and set alongside the previous studies. In these follow-ups, infant adopted children were tracked up to mid-life and compared with others born in similar circumstances and with those raised in two-parent families. We summarise findings on the long-term influence of factors in the prenatal period and in the adoptive home environment. We discuss how rearing in adoptive homes may provide protective effects in relation to internalising problems, but may not be as protective in relation to externalising outcomes. Implications for adoption policy and practice are drawn out.

婴儿国内收养跟进到成年：参考英国出生队列数据的考虑

考虑了对家庭收养婴儿的成人结果的研究：记录的心理和行为结果的范围、总结的知识现状以及所讨论的所选比较组的重要性。描述了婴儿收养的社会背景。我们对第 11 次世界大战后时期英国婴儿收养的后续调查结果进行了简要报告，并将其与之前的研究放在一起。在这些后续行动中，被领养的婴儿被追踪到中年，并与其他在类似情况下出生的孩子以及在双亲家庭中长大的孩子进行比较。我们总结了关于产前期和收养家庭环境中因素的长期影响的发现。我们讨论在收养家庭中的抚养如何可以提供与内化问题相关的保护作用，但对于外化结果可能没有那么大的保护作用。提出了对收养政策和实践的影响。
