Research has demonstrated that the extent to which an individual integrates a traumatic event into their identity ("trauma centrality") positively correlates with posttraumatic stress disorder (PTSD) symptom severity. No research to date has examined trauma centrality in individuals exposed to combat stress. This study investigated trauma centrality using the abridged Centrality of Event Scale (Berntsen & Rubin, 2006) among Operation Enduring Freedom/Operation Iraqi Freedom combat veterans (n = 46). Multiple regression analyses demonstrated that trauma centrality predicted PTSD symptoms. Trauma centrality and PTSD symptoms remained significantly correlated when controlling for depression in subgroups of veterans with or without probable PTSD. This study replicates and extends findings that placing trauma at the center of one's identity is associated with PTSD symptomatology.
研究表明，个体将创伤事件融入自身身份认同的程度（“创伤中心性”）与创伤后应激障碍（PTSD）症状的严重程度呈正相关。迄今为止，尚无研究探讨经历战斗应激的个体的创伤中心性。本研究使用缩短版事件中心性量表（Berntsen & Rubin，2006）对“持久自由行动/伊拉克自由行动”作战老兵（n = 46）进行了创伤中心性研究。多元回归分析表明，创伤中心性可预测 PTSD 症状。在 PTSD 可能性较高或较低的退伍军人亚组中，控制抑郁后，创伤中心性和 PTSD 症状仍呈显著相关。本研究复制并扩展了先前的研究结果，即把创伤置于个人身份的中心与 PTSD 症状有关。
