科罗拉多收养项目对398个收养家庭和生物学家庭进行了前瞻性纵向研究，研究了父母离婚和儿童适应之间的关联是由遗传因素介导的这一假设。在生物学家庭中，与父母婚姻保持完整的儿童相比，在12岁之前经历父母分离的儿童表现出更高的行为问题和物质使用率，以及更低的成就和社会适应水平。同样，与父母没有分开的被收养者相比，经历（收养）父母离婚的被收养儿童表现出更高的行为问题和物质使用水平，但在成就和社会能力方面没有差异。精神病理学的研究结果是一致的父母离婚和儿童的调整之间的关联与环境介导的解释;相反，成就和社会调整的研究结果是一致的，涉及被动的基因型-环境相关性的遗传介导的解释。
The hypothesis that the association between parental divorce and children's adjustment is mediated by genetic factors was examined in the Colorado Adoption Project, a prospective longitudinal study of 398 adoptive and biological families. In biological families, children who experienced their parents' separation by the age of 12 years exhibited higher rates of behavioral problems and substance use, and lower Levels of achievement and social adjustment, compared with children whose parents' marriages remained intact. Similarly, adopted children who experienced their (adoptive) parents' divorces exhibited elevated levels of behavioral problems and substance use compared with adoptees whose parents did not separate, but there were no differences on achievement and social competence. The findings for psychopathology are consistent with an environmentally mediated explanation for the association between parent divorce and children's adjustment; in contrast, the findings for achievement and social adjustment are consistent with a genetically mediated explanation involving passive genotype-environment correlation.
