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.
21名曾遭遇机动车事故(MVA)的儿童和青少年(年龄范围8 - 17岁,平均12.7岁),以及14名年龄和性别匹配的非MVA对照组,接受了一项心理生理评估,在基线以及两个应激阶段(心算、聆听并想象与自己经历类似的机动车事故)测量心率、收缩压和舒张压以及皮肤电导率。目前符合创伤后应激障碍(PTSD)或亚综合征PTSD标准的8名青少年,相较于13名未患PTSD的MVA青少年或14名非MVA对照组,显著报告称对MVA录音带的主观痛苦更多。所有组在心算时均有生理反应。然而,与预期相反,在对创伤回忆性刺激的反应中,各组之间没有差异生理反应。文中探讨了可能的解释。
