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.
本研究对出生时即与亲生父母分离的领养儿童进行了追踪，以评估遗传因素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，统计的是青少年时期的反社会行为，但不一定是犯罪行为。自变量有两种类型，即遗传因素和环境因素。遗传变量指的是亲生家庭的精神疾病诊断结果。环境变量是先前研究中确定的与青少年反社会行为相关的因素。我们的研究结果表明，在领养家庭中，患有精神疾病的家庭成员或养父母离婚对男孩的负面影响比对女孩更大。在遗传预测因素方面不存在显著的性别差异。在总样本中，预测反社会行为的遗传变量是有一个反社会或酗酒的亲生亲属。这一发现与其他关于反社会行为的遗传力研究结果一致。
