There is evidence that depressive symptoms are associated with attenuated physiological reactivity to active stressors. However, it is not known whether blunted reactivity in depressed individuals is stressor-specific. We examined cardiovascular and electrodermal reactivity in non-clinical participants with varying levels of depressive symptoms to different active and passive stressors. Depressive symptoms were inversely related to both blood pressure and skin conductance reactivity during a public speaking task and the viewing of the speech video. However, no effects were found during a cold pressor task. Together these findings suggest that depressive symptoms are related to attenuated sympathetic nervous system reactivity in response to self-relevant stressors.
有证据表明，抑郁症状与对主动应激源的生理反应减弱有关。然而，目前尚不清楚抑郁个体的反应迟钝是否与应激源特异性有关。我们研究了不同抑郁症状水平的非临床参与者在不同的主动和被动应激源下的心血管和皮肤电反应。在演讲任务和观看演讲视频期间，抑郁症状与血压和皮肤传导反应呈负相关。然而，在冷加压任务中没有发现影响。这些发现表明，抑郁症状与对自我相关应激源的交感神经系统反应减弱有关。
