Abstract

Higher lifetime trauma exposure and increased peritraumatic dissociation (PD) are well-known predictors of Post-Traumatic Stress Disorder (PTSD) symptoms following new trauma (prospective PTSD symptoms). The interplay between those factors, however, is not well established. In this study, we aimed to assess whether PD mediates the influence of lifetime trauma exposure on prospective PTSD symptoms. A total of 387 adults visiting five emergency departments who had experienced a traumatic event within 72 hours completed baseline assessments on lifetime trauma exposure count and PD. PTSD symptoms were assessed 1 month later. Structural equation modeling was used to examine the mediation effect of PD in the relationship between lifetime trauma exposure count and 1-month PTSD symptoms. We found that PD mediated the association between lifetime trauma exposure count and 1-month PTSD symptoms, even after accounting for some confounders. However, the mediation was partial, accounting for 17.9% of the lifetime trauma exposure count's total effect. While this finding is significant, it also suggests that additional mechanisms beyond PD play a role in explaining the influence of higher lifetime trauma exposure on prospective PTSD symptoms. These findings provide valuable insights into the complex dynamics of PTSD development and call for further research to explore complementary factors and preventive strategies.

创伤性分离对终生创伤暴露对未来创伤后应激障碍症状的影响具有部分中介作用。
众所周知,较高的终生创伤暴露和较高的创伤周解离(PD)是预测新创伤后创伤后应激障碍(PTSD)症状(前瞻性创伤后应激障碍症状)的因素。然而,这些因素之间的相互作用尚未得到很好的证实。在本研究中,我们旨在评估创伤后应激障碍是否会介导终生创伤暴露对未来创伤后应激障碍症状的影响。共有 387 名在 72 小时内经历过创伤事件的成年人到五个急诊科就诊,他们完成了关于终生创伤暴露次数和创伤后应激障碍的基线评估。一个月后对创伤后应激障碍症状进行评估。我们使用结构方程模型来研究创伤后应激障碍在终生创伤暴露次数与 1 个月创伤后应激障碍症状之间的中介效应。我们发现,即使考虑了一些混杂因素,创伤后应激障碍仍对终生创伤暴露次数与 1 个月创伤后应激障碍症状之间的关系起到了中介作用。然而,这种中介作用是部分的,只占终生创伤暴露次数总效应的 17.9%。虽然这一发现意义重大,但它也表明,在解释较高的终生创伤暴露对未来创伤后应激障碍症状的影响时,除了创伤后应激障碍之外,还有其他机制在发挥作用。这些发现为创伤后应激障碍的复杂动态发展提供了有价值的见解,并呼吁进一步研究以探索补充因素和预防策略。
