This study investigated whether adolescent vagal stress reactivity to parent-adolescent conflict moderates the effects of family instability on the development of adolescent behavioral problems. Participants were 192 adolescents ( age = 12.4) and their parents across 2 measurement occasions. Results indicated that the interaction between family instability and vagal stress reactivity significantly predicted change in externalizing problems. Greater family instability was associated with increases in externalizing problems only for adolescents showing greater vagal suppression (i.e., higher vagal reactivity) during a laboratory triadic family conflict discussion. Further tests suggested the interaction was consistent with diathesis stress, such that adolescents with higher vagal stress reactivity show higher increases in externalizing problems under high instability but not lower increases in externalizing symptoms with low family instability. Findings indicate disruptions in the proximal rearing contexts may differentially influence development for adolescents, but the impact may differ as a function of stress reactivity.

这项研究调查了青少年对亲子冲突的迷走神经应激反应是否能调节家庭不稳定对青少年行为问题发展的影响。研究对象为 192 名青少年（年龄=12.4 岁）及其父母，共进行了 2 次测量。结果表明，家庭不稳定与迷走神经应激反应的相互作用显著预测了外化问题的变化。只有在实验室三方家庭冲突讨论中表现出迷走神经抑制（即迷走神经反应性更高）的青少年，家庭不稳定程度增加与外化问题增加呈正相关。进一步的测试表明，这种相互作用与素质应激一致，即迷走神经应激反应较高的青少年在家庭不稳定程度较高时，其外化问题的增加幅度更高，但在家庭不稳定程度较低时，其外化症状的增加幅度不会更低。研究结果表明，近端养育环境的破坏可能会对青少年的发展产生不同的影响，但影响可能因应激反应的不同而不同。（美国心理协会，2019，版权所有）。
