Discrepancies regarding the link between autonomic nervous system (ANS) activity and psychopathology may be due in part to inconsistent measurement of non-psychological factors, including eating, drinking, activity, posture, and interacting with others. Rather than sources of noise, behaviors like being active and being with others may be the behavioral pathways that connect psychopathology symptoms to autonomic activity. The present study examined whether behaviors mediate the association of depression, anxiety, and hypomanic traits with ANS by using experience sampling methodology and ambulatory impedance cardiography. Participants (n = 49) completed measures of affect and one day of experience sampling and ambulatory impedance cardiography. The association of hypomanic traits with heart rate variability and heart rate was mediated by physical activity, and social activity mediated the association of depressive symptoms and respiration. These results highlight the importance of considering the pathways between psychopathology and ANS and the mediating role that everyday behaviors play.
自主神经系统 (ANS) 活动与精神病理学之间的联系存在差异，部分原因可能是对非心理因素的测量不一致，包括饮食、饮水、活动、姿势和与他人互动。与噪声源不同，活跃和与他人互动等行为可能是将精神病理学症状与自主活动联系起来的行为途径。本研究使用经验采样方法和动态阻抗心动描记术，检验了行为是否通过中介作用将抑郁、焦虑和轻躁狂特征与 ANS 联系起来。参与者（n=49）完成了情绪测量，并进行了一天的经验采样和动态阻抗心动描记术。轻躁狂特征与心率变异性和心率的关联由身体活动介导，而社会活动则介导了抑郁症状与呼吸的关联。这些结果强调了考虑精神病理学与 ANS 之间的途径以及日常行为的中介作用的重要性。
