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人员和阿富汗战争退伍军人的反应 在想象他们个人过去的创伤经历时。研究对象将 被诊断为创伤后应激障碍(PTSD)和非创伤后应激障碍 在年龄、自创伤指数以来经过的时间方面进行匹配的组， 严重的创伤暴露，以及共病的精神障碍。 该项目将在创伤应激实验室进行 俄罗斯科学院心理研究所研究，莫斯科， 在Nadja V.Tarabrina博士的指导下，第三十二期《剧本》 将在描述各种过去生活的主题的帮助下进行准备 经验，包括需要研究的具体创伤经历。 剧本将结合主观的内脏反应和肌肉反应 受试者记忆中伴随着每一次经历。剧本将会 被录制下来，以便在实验室回放。受试者将被指示 想象剧本所描绘的事件，而心率，皮肤 电导和面部肌肉肌电记录。 数据将通过双因素(创伤、诊断)进行分析 多变量方差分析(MANOVA)。此外，生理上的 俄罗斯创伤后应激障碍和非创伤后应激障碍受试者的反应将与 军地创伤后应激障碍与非创伤后应激障碍幸存者的反应 已经在美国和以色列用同样的方法进行了研究。这个 从这些较早的受试者导出的判别函数在 将考察俄罗斯创伤后应激障碍和非创伤后应激障碍受试者的分类。 这项工作的意义是双重的。首先，它将 将对一个重要的精神健康问题，即创伤后应激障碍的研究扩展到 俄罗斯核灾难工作者与战争的新文化群体 退伍军人。其次，它将应用一项经过验证的心理生理学研究 技术解决了以前没有研究过的影响的问题 “看不见”的心理创伤，在这种情况下可能造成伤害 不受核辐射影响。

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.
