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.
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.
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.
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.
家庭冲突与青少年时期的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，我们梳理了这种关联是否反映了因果效应，或者是否可以用共同的潜在原因（包括遗传因素）来解释。
在双胞胎数据中，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之间的关联模型，包括相互因果关系、家庭冲突单向导致自我控制能力低、自我控制能力低单向导致家庭冲突以及共同遗传易感性。我们纳入了来自荷兰双胞胎登记处的一个年龄在 14 岁的双胞胎大样本数据（N=9173）。
结果表明，家庭冲突导致青少年时期自我控制能力低的单向路径模型，遗传因素也在解释这种关联中发挥作用。
经历家庭冲突的青少年有自我控制能力受损的风险，家庭冲突通过共同的遗传因素以及直接的因果影响，成为自我控制能力低的一个强有力的预测指标。
