This study examined how pre-existing emotional and personality vulnerability factors affect responses to an analogue trauma experience. Sixty-eight undergraduate participants viewed a distressing film and completed measures of trait anxiety, intelligence, depression, trait dissociation, as well as changes in state anxiety, then recorded intrusions over the following week. Results revealed that trait anxiety, depression, trait dissociation, change in anxiety, and post-state anxiety were associated with intrusion frequency. Post-state anxiety mediated the relationship between trait anxiety, depression and trait dissociation, and intrusions. Implications for PTSD theories and laboratory trauma analogue research examining specific elements of cognitive models of PTSD are discussed.
本研究考察了预先存在的情绪和人格易损因素如何影响对模拟创伤经历的反应。68名本科参与者观看了一部令人痛苦的影片，并完成了特质焦虑、智力、抑郁、特质解离的测量，以及状态焦虑的变化，然后在接下来的一周记录侵入情况。结果显示，特质焦虑、抑郁、特质解离、焦虑变化和状态后焦虑与侵入频率相关。状态后焦虑介导了特质焦虑、抑郁和特质解离与侵入之间的关系。文中讨论了对创伤后应激障碍（PTSD）理论以及检验PTSD认知模型特定要素的实验室创伤模拟研究的启示。
