Psychophysiological assessment data, including heart rate (HR), blood pressure, and frontal electromyogram (EMG) responses to mental arithmetic, idiosyncratic audiotape descriptions of motor vehicle accidents (MVAs), and a standard videotape of MVAs, were collected on 105 injured victims of recent MVAs and 54 non-MVA controls. Their data replicated data from an earlier report (Blanchard et al., 1994) and support the utility of HR response to the audiotaped description of the MVA as useful in distinguishing MVA victims with PTSD from those with subsyndromal PTSD and non-PTSD. At a 1-year follow-up, the psychophysiological assessment was repeated on 125 MVA victims; results showed a general diminution of psychophysiological responding. Initial psychophysiological assessment results predicted 1-year follow-up clinical status (continued PTSD or full or partial remission) for 37 or 48 individuals who initially met criteria for PTSD.
收集了105名近期机动车事故（MVA）受伤受害者和54名非MVA对照者的心理生理评估数据，包括心率（HR）、血压以及对心算、机动车事故的个性化录音描述和标准机动车事故录像带的额肌电图（EMG）反应。他们的数据复制了早期报告（Blanchard等人，1994年）中的数据，并支持心率对机动车事故录音描述的反应在区分患有创伤后应激障碍（PTSD）的MVA受害者与患有亚综合征PTSD和非PTSD者方面的效用。在1年随访时，对125名MVA受害者重复进行了心理生理评估；结果显示心理生理反应普遍减弱。最初的心理生理评估结果预测了37名或48名最初符合PTSD标准的个体在1年随访时的临床状态（持续PTSD或完全或部分缓解）。
