后收容儿童（PI）中最常见的社会异常行为是不受抑制的社会参与（DSE，也称为不加区分的友好）。没有衡量这种现象的黄金标准，也没有关于如何将其与规范行为区分开来的共识。我们采用发展精神病理学方法来研究这一现象，将其与规范的社会发展进行比较，并研究了50名新被收养的PI儿童（被收养时16-36个月）与41名早期被收养的海外儿童和47名非被收养儿童（NA）的长期模式。通过对儿童与不熟悉的成年人互动的编码行为观察，将非典型行为与规范行为区分开来。主成分分析确定了社会去抑制的两个维度。非物质社会维度（例如，入会、接近）在NA儿童中表现出广泛的差异，因此被认为是社交的典型形式。身体接触和亲密的表现在NA儿童中很少见，这表明他们代表了一种非典型的行为模式。两组被收养的儿童都表现出比非收养儿童更多的身体DSE行为。在非身体因素上没有组间差异，并且随着时间的推移在所有组中都有所增加。对理解DSE的病因和未来方向的意义进行了讨论。
The most commonly reported socially aberrant behavior in postinstitutionalized (PI) children is disinhibited social engagement (DSE; also known as indiscriminate friendliness). There is no gold standard for measurement of this phenomenon or agreement on how to differentiate it from normative behavior. We adopted a developmental psychopathology approach to study this phenomenon by comparing it to normative social development and by studying its patterns over time in 50 newly adopted PI children (16–36 months at adoption) compared with 41 children adopted early from foster care overseas and 47 nonadopted (NA) controls. Using coded behavioral observations of the child’s interaction with an unfamiliar adult, atypical behaviors were differentiated from normative behaviors. Principal components analysis identified two dimensions of social disinhibition. The nonphysical social dimension (e.g., initiations, proximity) showed wide variation in NA children and is therefore considered a typical form of sociability. Displays of physical contact and intimacy were rare in NA children, suggesting that they represent an atypical pattern of behavior. Both adopted groups demonstrated more physical DSE behavior than NA children. There were no group differences on the nonphysical factor, and it increased over time in all groups. Implications for understanding the etiology of DSE and future directions are discussed.
