The relationship between event centrality (i.e., the degree to which a stressful event is integrated into one's identity) and acute posttraumatic outcomes after relatively minor physical injury is unknown. We examined pre-injury and Emergency Department (ED) predictors of event centrality at 6-weeks post-injury, and whether event centrality is uniquely associated with 6-week posttraumatic outcomes.
In the EDs of two Level I trauma centers, 149 patients completed surveys regarding demographic, psychological and injury-related factors within 24 h post-injury; 84 patients (51% male) completed 6-week surveys of event centrality, posttraumatic stress symptoms (PTSS) and trauma-specific QOL (T-QoL). Data were analyzed using linear regression modeling.
At least 20% of patients agreed or strongly agreed that the injury changed their life. Hospitalization status and peritraumatic dissociation were significant predictors of event centrality at 6-weeks. After controlling for demographics, ED-related factors and pre-injury PTSS, event centrality was uniquely associated with PTSS (p < .001) and T-QOL (p < .001) at 6 weeks.
Over and above the effects of the injury itself, event centrality conveyed important information for posttraumatic outcomes at 6 weeks post-injury. The centrality scale is brief and feasible to administer; future work is needed to determine the predictive utility of event centrality on post-injury outcomes.
事件核心度（即压力事件与一个人身份的融合程度）与相对较小的身体损伤后急性创伤后结局之间的关系尚不清楚。我们研究了受伤前和急诊部（ED）对受伤后 6 周时事件核心度的预测因素，以及事件核心度是否与 6 周后的创伤后结局有独特的相关性。
在两个一级创伤中心的 ED 中，149 名患者在受伤后 24 小时内完成了关于人口统计学、心理和损伤相关因素的调查；84 名患者（51%为男性）完成了 6 周的事件核心度、创伤后应激症状（PTSS）和创伤特异性 QOL（T-QoL）调查。使用线性回归模型分析数据。
至少 20%的患者同意或强烈同意受伤改变了他们的生活。住院状态和创伤前解离是 6 周时事件核心度的显著预测因素。在控制人口统计学、ED 相关因素和受伤前的 PTSS 后，事件核心度与 6 周时的 PTSS（p<0.001）和 T-QoL（p<0.001）有独特的相关性。
除了损伤本身的影响外，事件核心度为受伤后 6 周的创伤后结局提供了重要信息。核心度量表简短可行，未来需要进一步研究事件核心度对受伤后结局的预测作用。
