PSYCHOPHYSIOLOGY OF VISIBLE AND INVISIBLE TRAUMA

该项目将利用心理生理学技术来评估 切尔诺贝利灾难工作者和阿富汗战争退伍军人的反应 在想象他们过去的创伤经历时。 受试者将 被诊断为创伤后应激障碍（PTSD）和非PTSD 组，在年龄，自指数创伤以来的时间， 创伤暴露的严重程度和共病精神障碍。 该项目将在创伤压力实验室进行 俄罗斯科学院心理学研究所，莫斯科， 由Nadja V. Tarabrina博士指导 第三十二章“剧本” 将准备与援助的主题描述各种过去的生活 经验，包括要研究的具体创伤经历。 剧本将包含主观的内脏和肌肉反应 伴随着每一次经历的记忆。 这些脚本将 在实验室里回放。将指导受试者 想象剧本中所描绘的事件，而心率，皮肤 记录电导和面部肌肉肌电图。 将通过双因素（创伤、诊断）分析数据 多变量方差分析（MANOVA）。 此外，生理 俄罗斯PTSD和非PTSD受试者的反应将与 军人和平民创伤后应激障碍和非创伤后应激障碍创伤幸存者的反应 已经在美国和以色列用同样的方法进行了研究。 的 成功的判别函数来自这些早期的主题， 将对俄罗斯PTSD和非PTSD受试者进行分类。 所要进行的工作具有双重意义。 一是 将研究扩展到一个重要的心理健康问题，即，创伤后应激障碍， 俄罗斯核灾难工作者和战争的新文化人口 老兵 第二，它将应用一个行之有效的心理生理研究 技术对以前未研究的问题的影响 “看不见的”心理创伤，在这种情况下伤害的可能性 免受核辐射

This project will utilize psychophysiologic techniques to assess the responses of Chernobyl disaster workers and Afghanistan war veterans during imagery of their personal past traumatic experience. Subjects will be diagnosed into post-traumatic stress disorder (PTSD) and non-PTSD groups, matched with regard to age, time elapsed since the index trauma, severity of traumatic exposure, and comorbid mental disorders. The project will be performed at the Laboratory for Traumatic Stress Studies, Institute of Psychology, Russian Academy of Sciences, Moscow, under the direction of Nadja V. Tarabrina, Ph.D. Thirty-second "scripts" will be prepared with the aid of the subject describing various past life experiences, including the specific traumatic experiences to be studied. The scripts will incorporate subjective visceral and muscular reactions that the subject remembers accompanied each experience. The scripts will be recorded for playback in the laboratory. The subject will be instructed to imagine the events the scripts portray, while heart rate, skin conductance, and facial muscle electromyograms are recorded. The data will be analyzed by means of two-factor (Trauma, Diagnosis) multivariate analysis of variance (MANOVA). In addition, the physiologic responses of the Russian PTSD and non-PTSD subjects will be compared with the responses of military and civilian PTSD and non-PTSD trauma survivors already studied with the same methodology in the U.S.A. and Israel. The success of a discriminant function derived from these earlier subjects in classifying Russian PTSD and non-PTSD subjects will be examined. The significance of the work to be performed is two-fold. First, it will extend research into an important mental health problem, i.e., PTSD, to a new cultural population of Russian nuclear disaster workers and war veterans. Second, it will apply a proven psychophysiologic research technique to the previously unstudied question of the effect of "invisible" psychological trauma, in this case the possibility of harm from nuclear radiation.
