Genetic factors are important for the association between parental negativity and child problem behavior, but it is not clear whether this is due to passive or evocative genotype-environment correlation (rGE). In this study, we applied the extended children-of-twins model to directly examine the presence of passive and evocative rGE as well as direct environmental effects in the association between parental criticism and adolescent externalizing problem behavior. The cross-sectional data come from the Twin and Offspring Study in Sweden (N = 909 pairs of adult twins) and from the Twin Study of Child and Adolescent Development (N = 915 pairs of twin children). The results revealed that maternal criticism was primarily due to evocative rGE emanating from their adolescent's externalizing behavior. On the other hand, fathers' critical remarks tended to affect adolescent problem behavior in a direct environmental way. This suggests that previously reported differences in caretaking between mothers and fathers also are reflected in differences in why parenting is associated with externalizing behavior in offspring.
遗传因素对于父母的消极性与儿童问题行为之间的关联很重要,但尚不清楚这是由于被动还是唤起型基因-环境相关(rGE)所致。在这项研究中,我们应用扩展的双生子子女模型来直接检验父母批评与青少年外化问题行为之间的关联中是否存在被动和唤起型 rGE 以及直接环境效应。横断面数据来自瑞典的双生子和后代研究(N = 909 对成年双胞胎)和儿童与青少年发展的双生子研究(N = 915 对双胞胎儿童)。结果表明,母亲的批评主要是由于青少年的外化行为引起的唤起型 rGE。另一方面,父亲的批评言论往往以直接的环境方式影响青少年的问题行为。这表明,先前报道的父母之间在养育方式上的差异也反映在为什么父母教养与后代的外化行为有关联的原因上存在差异。
