Abstract. Fly-in-fl y-out personnel in the Far North are exposed to extreme climatic, geographic, and production factors, and also remain in conditions of group isolation, which makes demands on fl y-in-fl y-out worker’ body that oft en exceed its reserves. Th e full adaptation impossibility is associated with unfavorable functional states of workers, which lead to a decrease in the level of mental health, productivity and work effi ciency. Job tasks of workers in various industries diff er in physical and physiological stress and in the degree of harmful production factors expression. Th e purpose of this study is to identify and describe the psychological adaptation features in fl y-in-fl y-out personnel in industrial enterprises of the Far North. Th e study involved 145 fl y-in-fl y-out workers of oil, gas, and diamond mining industries in the Far North, 82 fl y-in-fl y-out builders in the south of the Russian Federation, who were a comparison group to identify the psychological adaptation features of fl y-in-fl y-out personnel in the Far North. Research methods are psychophysiological and psychological testing aimed at diagnosing conscious self-regulation of voluntary human activity and subjective control as key characteristics of psychological adaptation of workers. Th e results obtained allow us to conclude about the similarity of psychological characteristics that contribute to the successful adaptation of fl yin-fl y-out personnel, regardless of the region where the industrial facility is located. Th ese include internality in the areas of achievement, failure, family relationships, health and illness, as well as modeling, performance evaluation, and autonomy as regulatory processes. At the same time, their expression is specifi c, depending on the region of the object location and the industry.

Background. ^e problem of human adaptation to extreme conditions of the Arctic remains relevant. People have di_erent adaptive potential to ensure the success of their activities and state adequate to loads at the psycho-emotional and physiological levels. Comprehensive research into determination of adaptability and parameters of adaptation to the conditions of the Arctic in workers may be a solution. Interrelationships between functional states and di_erent socio-psychological and personal qualities of participants revealed in our study also conGrm this relevance. Objective. ^e study aims identify and describe the dynamics of functional states in participants of the marine scientiGc expedition during the Arctic trip in conjunction with the personal characteristics of adaptability (internality, conscious self-regulation, socio-psychological qualities). Methods. ^e researchers applied objective psychophysiological instrumental methods, projective method M. Luscher’s colour test, subjective questionnaire “Well-being. Activity. Mood” by V.A. Doskin et al. Сharacteristics of adaptability (internality, conscious self-regulation, socio-psychological qualities) were assessed with questionnaires. Statistical analysis of the data was carried out with correlation analysis. Sample. 39 participants of a 20-day sea expedition to the Arctic. Results. Characteristics of the personal and socio-psychological potential of participants are presented; the dynamics of participants’ functional state during the expedition trip are described; statistically signiGcant relationships have been established between socio-psychological characteristics, individual-personal qualities (regulatory and internality) and objective, projective, and subjective-evaluative parameters of functional states. Conclusion. Adaptive characteristics include developed general internal control, in particular, moderate control (internality) in the Geld of achievements and in the Geld of failures, as well as conscious self-regulation of behavior. ^e dynamics of objective indicators of functional states is positively correlated with the level of subjective control in the Geld of failures, and changes in indicators of projective and subjective methods are associated with characteristics of socio-psychological adaptation, the level of subjective control and conscious self-regulation.
