The centrality of a traumatic event to one's autobiographical memory has been associated with posttraumatic stress disorder (PTSD) symptom severity. In the present study, we investigated the associations between specific features of event centrality (EC), as measured using the Centrality of Event Scale, and specific symptoms of PTSD. We computed a cross-sectional graphical lasso network of PTSD symptoms and specific features of EC in a sample of trauma-exposed individuals (n = 451), many of whom met the clinical threshold for a PTSD diagnosis. The graphical lasso revealed intrusive memories, negative trauma-related feelings, and the perception that the traumatic event was central to one's identity to be influential nodes. Viewing the future through the lens of one's trauma exposure was the EC feature most strongly linked to PTSD. Among all PTSD symptoms, blaming oneself or others for the traumatic event showed the strongest link to EC. The network was stable, allowing for reliable interpretations. Future longitudinal research is needed to clarify the associations among EC features and PTSD symptoms over time.

DSM-5 创伤后应激障碍症状和事件中心性的网络分析

创伤事件对一个人的自传体记忆的中心性与创伤后应激障碍 (PTSD) 症状的严重程度有关。在本研究中，我们调查了事件中心性 (EC) 的特定特征（使用事件中心性量表衡量）与 PTSD 的特定症状之间的关联。我们计算了创伤暴露个体样本中 PTSD 症状和 EC 特定特征的横截面图形套索网络（n =451)，其中许多人达到了 PTSD 诊断的临床阈值。图形套索揭示了侵入性记忆、与创伤相关的负面感受，以及认为创伤事件是一个人身份的核心，是有影响力的节点。通过一个人的创伤暴露的镜头来看待未来是与 PTSD 最密切相关的 EC 特征。在所有 PTSD 症状中，将创伤事件归咎于自己或他人与 EC 的联系最强。网络稳定，可以进行可靠的解释。需要未来的纵向研究来阐明 EC 特征和 PTSD 症状之间随时间推移的关联。
