父母慈爱、保持一致的规则、了解自己的行踪的青少年往往在多个领域表现出更适应的心理功能水平。行为遗传学研究已经证明了父母对受遗传影响的儿童特征和行为的敏感性。然而，养育行为之间的相关性是否是由重叠的父母效应、重叠的孩子效应或两者的某种组合驱动的问题仍然是开放的。在来自德克萨斯州双胞胎项目的N= 542对双胞胎样本中，年龄在13.6到20.1岁之间，我们评估了青少年受遗传影响的特征在多大程度上广泛影响养育的多个维度（母亲和父亲的温暖和控制，以及父母的监督）。我们发现，共享的环境因素主要占父母的温暖，控制和监测之间的协变。儿童驱动的遗传效应，主要检测到独特的父亲的养育变异。这些结果表明，青少年的家庭范围内的环境背景是一般在多个领域的养育，而遗传影响的一致性驱动的影响是特定的养育的特定方面和特定的关系。
Adolescents whose parents are affectionate, maintain consistent rules, and are knowledgeable about their whereabouts tend to exhibit more adaptive levels of psychological functioning across multiple domains. Behavioral genetic research has documented the sensitivity of parenting to genetically influenced child characteristics and behaviors. Yet, the question of whether the correlations between parenting behaviors are driven by overlapping parent effects, overlapping child effects, or some combination of the two remains open. In a sample of N= 542 twins, ages 13.6 to 20.1 years, from the Texas Twin Project, we evaluated the extent to which adolescents’ genetically influenced traits broadly affect multiple dimensions of parenting (maternal and paternal warmth and control, and parental monitoring). We found that shared environmental factors primarily accounted for the covariation among parental warmth, control, and monitoring. Child-driven genetic effects were primarily detected in parenting variance unique to fathers. These results indicate that adolescents’ family-wide environmental contexts are general across multiple domains of parenting, whereas genetically influenced adolescent-driven effects are specific to particular aspects of parenting and to particular relationships.
