There is growing research indicating that event centrality strongly predicts posttraumatic stress disorder (PTSD). However, there is not much research on what makes a traumatic event central to one's life story. One reason a traumatic memory becomes a reference point for one's life story is that it brings about significant changes in one's life. This study investigated the relationships between transitional impact of an event, event centrality, and PTSD symptoms. Specifically, it tested whether higher negative changes were associated with higher levels of event centrality and PTSD symptoms. It also investigated whether event centrality mediated the relationship between transitional impact and PTSD severity. 101 individuals diagnosed with PTSD completed the Transitional Impact Scale (TIS), Centrality of Event Scale, and Impact of Event Scale-Revised regarding their traumatic experiences. Furthermore, they responded to the Posttraumatic Stress Disorder Symptom Scale-Self Report (PSS-SR), Traumatic Events Checklist (TELC), and Beck Anxiety Inventory (BAI). Results indicate that (a) the TIS had valid and reliable psychometric properties in a PTSD sample, (b) most of the traumatic events received high negative psychological and material change scores, and (c) event centrality mediated the relationship between transitional impact and PTSD severity.
越来越多的研究表明，事件中心性强烈预测创伤后应激障碍（PTSD）。然而，对于是什么使创伤性事件成为一个人生活故事的核心，研究并不多。一个创伤性记忆成为一个人生活故事的参考点的一个原因是，它给一个人的生活带来了重大的变化。本研究调查了事件的过渡性影响、事件中心性和 PTSD 症状之间的关系。具体来说，它测试了更高的负面变化是否与更高的事件中心性和 PTSD 症状水平有关。它还调查了事件中心性是否在过渡性影响和 PTSD 严重程度之间起中介作用。101 名被诊断患有 PTSD 的人完成了关于他们创伤经历的过渡影响量表（TIS）、事件中心性量表和修订后的事件影响量表-R 。此外，他们还回答了创伤后应激障碍症状量表自我报告（PSS-SR）、创伤事件检查表（TELC）和贝克焦虑量表（BAI）。结果表明：（a）TIS 在 PTSD 样本中具有有效的、可靠的心理计量学特性；（b）大多数创伤性事件的心理和物质变化得分都很高；（c）事件中心性在过渡性影响和 PTSD 严重程度之间起中介作用。
