Psychological pain is a prominent symptom in people who experience depression, but its relation with physiological measures has not been explored. This study compared two measures of psychological pain, the Orbach & Mikulincer Mental Pain (OMMP) questionnaire and the Psychache Scale, for their relationship with resting-state heart rate variability (HRV) in 35 adults with a history of depression. Low-frequency HRV decreased significantly with increasing psychological pain, particularly in participants who did not use antidepressants, while the beat-to-beat fractal dimension decreased in participants who did use antidepressants. Neither heart rate nor high-frequency HRV was associated with psychological pain. These results suggest a state of arousal characterized by increased sympathetic activity. Results also indicate that the OMMP may be a more accurate measure of autonomic arousal associated with current psychological pain than the Psychache Scale.
心理疼痛是抑郁症患者的一个突出症状，但尚未探究其与生理指标之间的关系。本研究比较了两种心理疼痛测量方法，即奥尔巴赫和米库林纳心理疼痛（OMMP）问卷和心理痛苦量表，以探讨它们与35名有抑郁症病史的成年人静息心率变异性（HRV）之间的关系。随着心理疼痛加剧，低频HRV显著降低，尤其是未使用抗抑郁药的参与者，而逐搏分形维数在使用抗抑郁药的参与者中降低。心率和高频HRV均与心理疼痛无关。这些结果表明存在一种以交感神经活动增加为特征的唤醒状态。结果还表明，与心理痛苦量表相比，OMMP可能是一种更准确测量与当前心理疼痛相关的自主神经唤醒的方法。
