This study sought to replicate past research that has shown differences in physiological responsiveness among survivors of motor vehicle accidents (MVAs) with posttraumatic stress disorder (PTSD) and those survivors who do not develop this disorder. Such physiological differences have been found specifically with heart rate (HR) reactivity. This study also attempts to account for differences among those survivors with PTSD who do respond physiologically in laboratory situations and those who do not show a physiological response when presented with audiotaped descriptions of their accidents. Results replicated the significant differences in HR reactivity between diagnostic groups with chronic PTSD versus those with subsyndromal PTSD and non-PTSD. Variables related to the severity of the diagnosis and trauma were found to discriminate between physiological responders and nonresponders with chronic PTSD.
本研究旨在重复以往的研究，该研究表明，患有创伤后应激障碍（PTSD）的机动车事故（MVA）幸存者与未患该障碍的幸存者之间存在生理反应差异。这种生理差异尤其体现在心率（HR）反应性方面。本研究还试图解释那些在实验室情境中出现生理反应的PTSD幸存者与那些在听事故录音描述时未表现出生理反应的幸存者之间的差异。研究结果重现了慢性PTSD诊断组与亚综合征PTSD及非PTSD诊断组之间HR反应性的显著差异。研究发现，与诊断和创伤严重程度相关的变量能够区分慢性PTSD的生理反应者和无反应者。
