21名发生过机动车事故（MVA）的儿童和青少年（年龄范围8-17岁，平均12.7岁），以及14名年龄和性别相匹配的非MVA对照组，接受了心理生理学评估，在基线和两个应激源阶段：心算和听并想象他们自己的MVA时，测量了心率、收缩压和舒张压和皮肤电导。8名目前符合PTSD或亚症候群PTSD标准的青年在MVA录音中比13名MVA非PTSD青年或14名非MVA对照者报告了更多的主观痛苦。所有小组都对心算有生理上的反应。然而，与预期相反的是，各组之间对创伤刺激的生理反应没有差异。探讨了可能的解释。
Twenty-one children and adolescents (age range 8-17, mean 12.7 years) who had been in motor vehicle accidents (MVAs), and 14 non-MVA controls matched for age and gender, underwent a psychophysiological assessment in which heart rate, systolic and diastolic blood pressure, and skin conductance were measured during baseline and two stressor phases: mental arithmetic and listening to and imagining a MVA like their own. The eight youth who currently met criteria for PTSD or sub-syndromal PTSD significantly reported more subjective distress to the MVA audiotape than the 13 MVA non-PTSD youth or the 14 non-MVA controls. All groups responded physiologically to the mental arithmetic. However, in contrast to expectations, there were no differential physiological responses among the groups to the stimuli reminiscent of the trauma. Possible explanations are explored.
