高心脏迷走神经控制（通过呼吸性窦性心律不齐测量; RSA）与较低的抑郁相关。最近的理论认为，人们对社会资源的反应是这种联系的关键机制。这一论点意味着两个假设：第一，只有当社会资源（社会支持）可用时，高RSA才与抑郁症状的减少有关;第二，利用可用的社会资源（社会参与）应该作为RSA的积极影响的机制。为了验证这些假设，我们测量了131名成年人的RSA。参与者报告了他们的社会支持，社会参与和抑郁症状。六个月后，他们再次报告了他们的抑郁症状。具有较高RSA的参与者在六个月后报告了较少的抑郁症状，但仅在高社会支持的条件下。RSA和社会支持在预测抑郁症状中的相互作用完全由社会参与介导。这些发现为心脏迷走神经控制通过社会过程有助于减少抑郁症状的观点提供了重要支持。生物敏感性的背景和差异易感性理论以及抑郁症的预防和治疗的影响进行了讨论。
High cardiac vagal control (as measured by respiratory sinus arrhythmia; RSA) is associated with lower depression. Recent theories argue that people’s responsiveness to social resources is a key mechanism in this association. This argument implies two hypotheses: first, high RSA should be related to decreased depressive symptoms only when social resources (social support) are available; second, utilization of available social resources (social engagement) should serve as a mechanism for the positive effects of RSA. To test these hypotheses, we measured RSA in 131 adults. Participants reported their social support, social engagement, and depressive symptoms. Six months later, they again reported their depressive symptoms. Participants with higher RSA reported fewer depressive symptoms six months later, but only under conditions of high social support. The interaction between RSA and social support in predicting depressive symptoms was fully mediated by social engagement. These findings provide crucial support for the idea that cardiac vagal control contributes to decreased depressive symptoms via social processes. Implications for biological sensitivity to context and differential susceptibility theories as well as for the prevention and treatment of depression are discussed.
