OBJECTIVE Family conflict is associated with low self-control in adolescence. Thus far research about the direction of this association is inconclusive. In this study, we sort out whether this association reflects a causal effect or whether it is explained by a common underlying cause, including genetic factors. METHOD In twin data, we fitted a series of causal models, and compared models for the association of family conflict and self-control including reciprocal causation, unidirectional causation from family conflict to low self-control, unidirectional causation from low self-control to family conflict, and common genetic susceptibility. We included data from a large sample of twins aged 14 years (N = 9,173), all enrolled in the Netherlands Twin Register. RESULTS The results suggested a unidirectional pathway model in which family conflict leads to low self-control in adolescence, with genetic factors also playing a role in explaining the association. CONCLUSION Adolescents experiencing family conflict are at risk for showing hampered self-control capacities, with family conflict being a robust predictor of low self-control through common genetic factors but also through direct causal influences.

失控：在基因敏感的设计中检查家庭冲突与青春期自我控制之间的联系。

目的家庭冲突与青春期自我控制能力低有关。迄今为止，关于这种关联的方向的研究尚无定论。在这项研究中，我们对这种关联是否反映出因果关系进行了梳理，还是通过包括遗传因素在内的常见根本原因对其进行了解释。方法在双数据中，我们拟合了一系列因果模型，并比较了家庭冲突和自我控制的关联模型，包括相互因果关系，从家庭冲突到低自我控制的单向因果，从低自我控制到家庭的单向因果。冲突和常见的遗传易感性。我们纳入了来自14岁（N = 9,173）的大量双胞胎样本的数据，所有这些样本均已登记在荷兰双胞胎登记册。结果结果提示单向途径模型，其中家庭冲突导致青春期自我控制力低，遗传因素在解释这种关联中也起着作用。结论经历家庭冲突的青少年处于表现出自我控制能力受阻的危险之中，家庭冲突是通过常见遗传因素以及直接因果关系影响自我控制能力低下的强有力的预测指标。
