Children abandoned to institutions display a host of developmental delays, including those involving general cognition and language. The majority of published studies focus on children over 3 years of age; little is known about whether these delays may be detected earlier when children undergo rapid lexical development. To investigate the early language development of children raised in institutional settings in the Russian Federation, we compared a group of children in institutional care (n = 36; 8–35 months) to their age‐matched peers raised in biological families, who have never been institutionalized (n = 72) using the Russian version of the CDI. The results suggest that institutionalization is associated with pronounced delays in children's early language development with large and robust effect sizes. Among children with a history of institutionalization, these delays are also associated with difficulties in Daily Living skills, communication, and socialization.

俄罗斯在机构照料​​中提高了儿童的早期词汇发展能力。

被遗弃到机构中的儿童表现出许多发育迟缓，包括涉及一般认知和语言的迟缓。大部分已发表的研究集中于3岁以上的儿童。对于儿童进行快速词汇发展时，是否可以及早发现这些延迟知之甚少。为了调查俄罗斯联邦在机构环境中抚养的儿童的早期语言发展，我们将一组在机构照料​​中的儿童（n  = 36； 8-35个月）与他们的同龄生物家庭中同龄的同龄人进行了比较，他们从未已经制度化（ñ = 72）使用俄语版本的CDI。结果表明，机构化与儿童早期语言发展的明显延迟有关，且效应大小较大且稳健。在有寄养史的儿童中，这些延误还与日常生活技能，沟通和社交方面的困难有关。
