本研究追踪出生时与亲生父母分离的被收养者，以评估遗传和环境因素在青少年反社会行为中的重要性。因变量是一个反社会症状计数，符合反社会，但不一定是犯罪行为在青春期。自变量有两种类型，遗传和环境。遗传变量是指生物学家族的精神病诊断。环境变量是指那些被先前的研究确定为与青少年反社会行为相关的变量。我们的研究结果表明，男孩比女孩更容易受到精神病收养家庭成员或养父母离婚的不利影响。在遗传预测因子方面没有显著的性别差异。在总样本中，预测反社会行为的遗传变量是有反社会或酗酒的生物学亲属。这一发现与其他反社会行为的遗传性研究一致。
The present study follows up adoptees separated at birth from the biologic parents to assess the importance of genetic and environmental factors in adolescent antisocial behavior. The dependent variable is an antisocial symptom count that tallies antisocial but not necessarily criminal behaviors in adolescence. The independent variables are of two types, genetic and environmental. Genetic variables refer to psychiatric diagnoses of the biologic family. Environmental variables are those identified by previous research as associated with adolescent antisocial behavior. Our results indicate that boys are more vulnerable than girls to the adverse effects of a psychiatrically ill adoptive family member or divorce in the adoptive parents. There is not a significant sex difference in genetic predictors. In the total sample, the genetic variables that predict antisocial behavior are having an antisocial or alcoholic biologic relative. This finding is in agreement with other heritability studies of antisocial behavior.
