ABSTRACT Internationally adopted children show higher rates of disinhibited social behavior (DSB). Two competing explanations for DSB include difficulties in attachment specifically and deficits in inhibitory control more generally. This four-wave longitudinal study (a) documented the persistence of DSB among internationally adopted children and (b) tested the relative contributions of attachment environment versus inhibitory control difficulties in the persistence of DSB. Improvement in DSB was found 3 to 4 years post-adoption for the sample as a whole, although heterogeneity within the sample was present. Results from structural equation modeling and another test of mediation both indicated that the association between early deprivation and DSB was mediated by general difficulties with inhibitory control, not by attachment environment.

国际收养儿童的不受约束的社会行为是由依恋环境还是儿童的抑制性控制困难介导的？

摘要 国际收养的儿童表现出更高的社会行为抑制率（DSB）。DSB 的两个相互竞争的解释包括具体的依恋困难和更普遍的抑制控制缺陷。这项四波纵向研究 (a) 记录了国际收养儿童中 DSB 的持续性，并且 (b) 测试了依恋环境与抑制性控制困难对 DSB 持续性的相对贡献。尽管样本内存在异质性，但在采用后 3 至 4 年，整体样本发现 DSB 有所改善。结构方程模型和另一个中介测试的结果都表明，早期剥夺和 DSB 之间的关联是由抑制控制的一般困难介导的，而不是由依恋环境介导的。
