背景：人格解体障碍（DPD）患者通常抱怨情绪脱离。先前的研究发现，与焦虑症患者相比，DPD患者对情绪刺激的自主神经反应性降低。我们的目的是研究与对照组相比，DPD患者对情绪听觉刺激的自主神经反应。此外，我们还研究了正念呼吸对这些反应以及去人格化强度的调节作用。方法比较22例DPD患者和15例对照患者的抑郁、焦虑程度、年龄、性别和受教育程度的差异：1)静息期皮电和心率数据；2)正常听力和正念呼吸两种条件下标准化声情感刺激的自主神经反应和认知评价。结果与对照组和标准化标准评分相比，DPD患者对情绪声音的评分明显更中性。然而，与此同时，他们对声音情绪刺激的反应更强烈，与对照组相比，他们的皮肤电反应模式更受效价和觉醒的调节。正念呼吸降低了DPD患者人格解体的严重程度，并增加了整个样本中皮电反应的唤醒调节。最后，与对照组相比，DPD患者在休息期间表现出更高的皮肤电稳定性。结论DPD患者对情绪声音的认知评价与其对这些情绪刺激的自主神经反应是脱节的。DPD患者皮肤电不稳定性的增加可能反映了内向性和情绪冲动认知控制的增加。这些发现具有重要的心理治疗意义。
Background Patients with depersonalization disorder (DPD) typically complain about emotional detachment. Previous studies found reduced autonomic responsiveness to emotional stimuli for DPD patients as compared to patients with anxiety disorders. We aimed to investigate autonomic responsiveness to emotional auditory stimuli of DPD patients as compared to patient controls. Furthermore, we examined the modulatory effect of mindful breathing on these responses as well as on depersonalization intensity. Methods 22 DPD patients and 15 patient controls balanced for severity of depression and anxiety, age, sex and education, were compared regarding 1) electrodermal and heart rate data during a resting period, and 2) autonomic responses and cognitive appraisal of standardized acoustic affective stimuli in two conditions (normal listening and mindful breathing). Results DPD patients rated the emotional sounds as significantly more neutral as compared to patient controls and standardized norm ratings. At the same time, however, they responded more strongly to acoustic emotional stimuli and their electrodermal response pattern was more modulated by valence and arousal as compared to patient controls. Mindful breathing reduced severity of depersonalization in DPD patients and increased the arousal modulation of electrodermal responses in the whole sample. Finally, DPD patients showed an increased electrodermal lability in the rest period as compared to patient controls. Conclusions These findings demonstrated that the cognitive evaluation of emotional sounds in DPD patients is disconnected from their autonomic responses to those emotional stimuli. The increased electrodermal lability in DPD may reflect increased introversion and cognitive control of emotional impulses. The findings have important psychotherapeutic implications.
