The objective of the present article was to examine the mediational significance of peritraumatic dissociation in the relationship between peritraumatic distress and posttraumatic stress disorder (PTSD). A total of 71 individuals with spinal cord injuries completed interviews and questionnaires measuring PTSD symptomatology, peritraumatic dissociation, and peritraumatic distress. Peritraumatic dissociation was found to partially mediate the relationship between peritraumatic distress and PTSD symptomatology. These findings provide support for the hypothesis that peritraumatic distress and peritraumatic dissociation significantly impact PTSD severity. The findings also support the hypothesis that peritraumatic dissociation is provoked by peritraumatic distress. The results further indicate that although peritraumatic dissociation seems to be a significant risk factor for PTSD, it is not necessary for the development of PTSD; the presence of peritraumatic distress may be sufficient. These findings highlight the importance of investigating peritraumatic reactions after a traumatic event in order to identify individuals at risk for developing PTSD. Such a practice may help prevent the development of chronic conditions.
本文旨在探讨创伤后分离在创伤后应激障碍（PTSD）与创伤时痛苦之间关系中的中介作用。共有 71 名脊髓损伤患者完成了访谈和问卷调查，评估 PTSD 症状、创伤时分离和创伤时痛苦。创伤时分离部分中介了创伤时痛苦和 PTSD 症状之间的关系。这些发现为创伤时痛苦和创伤时分离显著影响 PTSD 严重程度的假设提供了支持。这些发现还支持创伤时分离由创伤时痛苦引发的假设。结果进一步表明，尽管创伤时分离似乎是 PTSD 的一个重要风险因素，但它并不是 PTSD 发展的必要条件；创伤时痛苦的存在可能就足够了。这些发现强调了在创伤事件后调查创伤时反应的重要性，以便识别可能发展为 PTSD 的个体。这种做法可能有助于预防慢性疾病的发生。
