Objective indicators of posttraumatic dissociation

游离是一种心理现象，可伴随各种精神障碍。典型的症状只持续几分钟，包括人格解体、现实感丧失和情绪体验的改变。症状还表现为感觉知觉和情绪体验下降。为了确定分离过程中的神经生物学变化，以前的研究几乎只关注主观体验的报告。到目前为止，这种方法是有问题的，因为报告受到症状本身的阻碍，而且很少有常见的可操作结构。到目前为止，还没有经验数据可以客观地量化分离的严重程度。然而，这对于理解解离的神经生物学相关性及其对治疗过程的影响至关重要。因此，我们的目的是在实验设计中检查抑郁的客观标记。根据文献，已经确定了以下潜在的标志：疼痛感觉降低，嗅觉感觉降低，肌肉张力增强和心血管改变。在一个具有症状激发的实验设计中，这些参数被检查作为分离标记的可用性。

Dissociation is a psychological phenomenon, which can accompany various mental disorders. Typical symptoms last only minutes and involve depersonalization, derealization und changes of emotional experience. The symptomatalogy is furthermore characterized by a reduced sensory perception and emotional experience. In order to identify neurobiological changes in dissociation, previous research focused almost solely on reports of subjective experiences. This approach is problematic insofar, as the reports are hindered by the symptomatology itself and as there are few common operationalized constructs. Up to now, no empirical data is available which allows an objective quantification of the severity of dissociation. This is however pivotal in order to understand the neurobiological correlates of dissociation and its impact on the therapeutic process. We therefore aim to examine objective markers of depression in an experimental design. Based on the literature, the following potential markers have been identified: reduced pain perception, reduced olfactory perception, enhanced muscle tonus and cardiovascular changes. In an experimental design with symptom provocation, those parameters are examined for their usability as markers for dissociation.
