本研究探讨了目睹死亡和受伤是否会产生心理生理反应性创伤后应激障碍（PTSD）。参与者包括患有当前PTSD （n = 17）和从未患过PTSD （n = 21）的无药越战女护士退伍军人，与她们的服兵役有关。描述个人创伤性军事护理事件、标准军事护理事件和其他生活事件的个性化脚本被录音并播放给参与者，同时记录心率、皮肤电导和面部肌电图。创伤后应激障碍护士仅在与军事相关的护理事件意象中表现出比非创伤后应激障碍护士更大的生理反应。两组自我报告的情绪反应在想象过程中没有差异。心理生理学结果支持这样一个命题：目睹他人死亡和严重伤害的压力足以导致PTSD。
This study examined whether witnessing death and injury could produce psychophysiologically responsive posttraumatic stress disorder (PTSD). Participants consisted of medication-free female Vietnam nurse veterans with a diagnosis of current PTSD (n = 17) and who never had PTSD (n = 21), related to their military service. Individualized scripts describing personal traumatic military nursing events, a standard military nursing event, and other life events were tape recorded and played back to the participant while heart rate, skin conductance, and facial electromyograms were recorded. Nurses with PTSD showed significantly larger physiologic responses than non-PTSD nurses only during imagery of military-related nursing events. The groups' self-reported emotional responses did not differ during imagery. Psychophysiologic results support the proposition that witnessing death and serious injury to others is sufficiently stressful to cause PTSD.
