先前的文献综述表明，在收养研究中，共同的环境影响可能被低估了，因为被收养的个体暴露在有限的家庭环境中。本研究使用来自兄弟姐妹互动和行为研究（SIBS）的409个收养家庭和208个非收养家庭的样本来确定收养家庭表现出最大限制的环境维度，并确定这种限制对收养兄弟姐妹相关性估计的影响。与非收养家庭相比，收养家庭的父母去抑制性精神病理差异降低了41%，社会经济地位（SES）差异降低了18%。暴露于不良同伴模式、父母抑郁或家庭气候的范围限制证据有限。然而，父母去抑制性精神病理范围的限制和家庭经济地位对收养兄弟姐妹在犯罪、吸毒和智商方面的相关性没有影响。这些数据支持采用收养研究来直接估计共同环境影响对心理发展的重要性。
Previous reviews of the literature have suggested that shared environmental effects may be underestimated in adoption studies because adopted individuals are exposed to a restricted range of family environments. A sample of 409 adoptive and 208 nonadoptive families from the Sibling Interaction and Behavior Study (SIBS) was used to identify the environmental dimensions on which adoptive families show greatest restriction and to determine the effect of this restriction on estimates of the adoptive sibling correlation. Relative to non-adoptive families, adoptive families experienced a 41% reduction of variance in parent disinhibitory psychopathology and an 18% reduction of variance in socioeconomic status (SES). There was limited evidence for range restriction in exposure to bad peer models, parent depression, or family climate. However, restriction in range in parent disinhibitory psychopathology and family SES had no effect on adoptive-sibling correlations for delinquency, drug use, and IQ. These data support the use of adoption studies to obtain direct estimates of the importance of shared environmental effects on psychological development.
