Evaluation of interdependencies between psychometric parameters and spontaneous cerebral electric activity in the ChNPP accident clean up workers, evacuees from exclusion zone, and anti terrorist operation service men.
Psychometric and neurophysiological parameters were reviewed in the study subjects retro spectively and in comparison. Study population included the ChNPP accident clean up workers (ACUW), evacuees from the 30 kilometer exclusion zone, specifically in a sample from a cohort of the NRCRM Clinical Epidemiological Register (n=316), and anti terrorist operation servicemen (n=81) undergoing rehabilitation in the NRCRM Radiation psychoneurology department. A control group of persons (n=84) was also involved in the study. Diagnostic method ology for the characteristic personality features, namely the personality test of character accentuation by G. Shmishek and K. Leonhard, and Eysenck Personality Inventory (by H. J. Eysenck) were applied. Computer EEGs were registered and analyzed on the 16 channel electroencephalograph DX 4000 (Kharkiv, Ukraine).
In the aftermath of the emergency period, a personality deformation occurs in the clean up workers and survivors of the ChNPP accident, which is characterized by aggravation of such personality traits as jam (fixedness), emotiveness, pedantry, anxiety, cyclothymia, excitability and disthymia, with diminished hyperthymia and ostenta tion (demonstrability). Increased incidence of fixedness, pedantry, cyclothymia, affectability and disthymia with decreased hyperthymia were revealed in the group of ATO participants. Cerebral bioelectrical activity in the ChNPP ACUW was characterized by an increased delta activity power with decreased beta and theta activity power and dom inant frequency in comparison with all groups of survivors and control group. The ATO group was different from groups of survivors and control group with a lower power of delta, theta and beta activity, and a higher dominant frequency. Introversion featured a negative correlation with delta and theta activity index along with positive cor relation with alpha activity index. The absolute spectral power of beta, alpha and theta bands positively correlated with introversion. Increase in neuroticism featured a decrease in theta activity index and an increase in beta activ ity index along with decreased theta and delta band absolute spectral power.
There is a deformation of personality in the group of ChNPP ACUW, evacuees from the 30 kilometer zone and ATO servicemen. Deformation of personality correlates with abnormal cerebral bioelectrical activity.
评估切尔诺贝利核电站事故清理人员、禁区撤离人员以及反恐行动人员的心理测量参数与自发性脑电活动之间的相互依存关系。
对研究对象的心理测量和神经生理参数进行回顾性比较研究。研究人群包括切尔诺贝利核电站事故清理人员（ACUW）、30公里禁区的撤离人员，具体来自NRCRM临床流行病学登记队列中的一个样本（n = 316），以及在NRCRM放射精神神经科接受康复治疗的反恐行动人员（n = 81）。还纳入了一组对照人员（n = 84）参与研究。应用了用于评估特征性人格特征的诊断方法，即G. Shmishek和K. Leonhard的性格强化人格测试以及艾森克人格问卷（由H. J. 艾森克编制）。使用16通道脑电图仪DX 4000（乌克兰哈尔科夫）记录并分析计算机脑电图。
在应急期过后，切尔诺贝利核电站事故清理人员和幸存者出现人格变形，其特征为固执（僵化）、情绪化、迂腐、焦虑、环性心境障碍、易激惹和心境恶劣等人格特质加重，而情感高涨和炫耀（表现欲）减弱。在反恐行动参与者组中，发现固执、迂腐、环性心境障碍、易感性和心境恶劣的发生率增加，情感高涨减少。与所有幸存者组和对照组相比，切尔诺贝利核电站事故清理人员的大脑生物电活动特征为δ活动功率增加，β和θ活动功率及主导频率降低。反恐行动组与幸存者组和对照组不同，其δ、θ和β活动功率较低，主导频率较高。内向性与δ和θ活动指数呈负相关，与α活动指数呈正相关。β、α和θ波段的绝对频谱功率与内向性呈正相关。神经质增加表现为θ活动指数降低和β活动指数增加，同时θ和δ波段绝对频谱功率降低。
切尔诺贝利核电站事故清理人员组、30公里区域的撤离人员以及反恐行动人员存在人格变形。人格变形与异常的大脑生物电活动相关。
