The present study demonstrates the interplay between interparental relationship satisfaction and child plasticity in the origins of internalizing problems in 99 community mothers, fathers, and children. Our cumulative measure of plasticity integrated genetics (5-HTTLPR polymorphism), psychophysiology (skin conductance level), and observed behavior (inhibition, sadness, joy). The interaction between plasticity and interparental relationship satisfaction reflected differential susceptibility. Compared with low-plasticity peers, high-plasticity children had more internalizing problems from 5.5 to 12 years when the interparental relationship at 4.5 years was acrimonious, but fewer problems when it was harmonious. Further, almost half of the children in this sample were "differentially affected" by the interaction such that greater plasticity was associated with fewer internalizing problems when their parents had a harmonious relationship, a key feature of differential susceptibility.

本研究展示了在 99 位社区母亲、父亲和孩子中，亲子关系满意度和儿童可塑性在内在问题起源中的相互作用。我们的可塑性综合测量包括遗传学（5-HTTLPR 多态性）、心理生理学（皮肤电导水平）和观察到的行为（抑制、悲伤、喜悦）。可塑性和亲子关系满意度之间的相互作用反映了差异易感性。与低可塑性的同龄人相比，当 4.5 岁时的亲子关系恶劣时，高可塑性的孩子在 5.5 到 12 岁时会出现更多的内在问题，但当亲子关系和谐时，问题会更少。此外，该样本中几乎一半的孩子受到这种相互作用的“不同影响”，即当父母关系和谐时，较高的可塑性与较少的内在问题相关，这是差异易感性的一个关键特征。
