Dissociation is often considered to be a psychological defense mechanism used by victims of traumatic events (e. g., sexual abuse, physical punishment, or emotional abuse). Evidence for this view comes from studies that found a connection between self-reported traumatic childhood experiences and high levels of dissociation. However, there are some problems with this causal interpretation. The aim of this review is to summarize evidence that casts doubts on the commonly voiced view that the connection between self-reported trauma and dissociation is a simple and robust one. First, we briefly summarize studies that looked at the link between trauma and dissociation as well as studies that identified factors that may modulate this link. Second, we review studies that explored the psychological correlates of dissociation. Over the past few years, our knowledge of these correlates has increased considerably. Some of these correlates (e. g., fantasy proneness, suggestibility, and frontal lobe dysfunction) are especially relevant because they may undermine the accuracy of retrospective self-reports of trauma. Finally, we conclude that the link between trauma and dissociation is more complex than many clinicians seem to assume. In particular, the possibility that dissociation acts as an antecedent of self-reported trauma warrants serious attention.
解离通常被认为是创伤事件(如性虐待、体罚或情感虐待)受害者所使用的一种心理防御机制。这一观点的证据来自于一些研究,这些研究发现自我报告的童年创伤经历与高水平的解离之间存在联系。然而,这种因果解释存在一些问题。本综述的目的是总结一些证据,这些证据对一种普遍观点提出了质疑,即自我报告的创伤与解离之间的联系是简单而稳固的。首先,我们简要总结那些研究创伤与解离之间联系的研究,以及那些确定了可能调节这种联系的因素的研究。其次,我们回顾那些探索解离的心理相关因素的研究。在过去几年里,我们对这些相关因素的了解有了显著增加。其中一些相关因素(如意象性、易受暗示性和额叶功能障碍)尤其重要,因为它们可能会削弱创伤回顾性自我报告的准确性。最后,我们得出结论,创伤与解离之间的联系比许多临床医生似乎所认为的更为复杂。特别是,解离作为自我报告创伤的一个先行因素的可能性值得认真关注。
