有初步证据表明，增强启动创伤相关的线索发挥了作用，在创伤后应激障碍（PTSD）。对119名机动车事故幸存者的前瞻性研究调查了创伤相关刺激的启动是否预测PTSD。受试者在创伤后2周完成了一项修改后的词干完成测试，包括事故相关、交通相关、一般威胁和中性词。在6个月的随访中，对事故相关词汇的启动预测了PTSD，即使在PTSD和抑郁的初始症状水平以及对其他词汇的启动得到控制的情况下。这些结果与创伤性材料引发作用的增强有助于慢性PTSD发展的假设一致。
There is preliminary evidence that enhanced priming for trauma-related cues plays a role in posttraumatic stress disorder (PTSD). A prospective study of 119 motor vehicle accident survivors investigated whether priming for trauma-related stimuli predicts PTSD. Participants completed a modified word-stem completion test comprising accident-related, traffic-related, general threat, and neutral words at 2 weeks post-trauma. Priming for accident-related words predicted PTSD at 6 months follow-up, even when initial symptom levels of PTSD and depression and priming for other words were controlled. The results are in line with the hypothesis that enhanced priming for traumatic material contributes to the development of chronic PTSD.
