This study describes the features, manifestations and interrelationships of job stress, working capacity, professional performance and safety in loggers with a shift work organization in the North. This study involved 402 loggers. The research methods include questionnaires and psychophysiological diagnostics of stress and working capacity as well as questionnaires on the professional performance and safety of workers. The following statistical methods were used: correlation, multivariate dispersion and multi-regression stepwise analysis. It was found that the severity of stress, speed, accuracy and operator working capacity, as well as well-being, activity and mood in logging equipment operators, timber truck drivers and maintenance specialists statistically differ significantly. Higher professional stress and a more frequent decrease in professional performance are characteristic of truck drivers. Psychological and psychophysiological job stress and working capacity parameters are associated with the professional performance parameters of loggers. According to the results of a number of multi-regression analyses, the reduced professional performance markers of loggers include the index of stress, satiety, monotony and fatigue, vegetative balance and stress (method of M. Luscher and coefficients from G.A. Aminev), operator working capacity and reaction speed (CVMR). Full article

(1) Background: The vitamin D level in blood is one of the markers of the functional reserves of the human body and can contribute to more successful adaptation in the Arctic. (2) Methods: The study involved 38 participants in the project “Arctic Floating University—2021”. The determination of vitamin D content was carried out at the beginning of the expedition. A dynamic study was carried out for 20 days in the morning and in the evening. The functional state parameters of the participants were assessed using psychophysiological and questionnaire methods. Statistical methods: Mann–Whitney U-test and correlation analysis. (3) Results: It was found that at the beginning of the expedition, the functional state of participants with more severe vitamin D deficiency is characterized by a shorter average duration of RR intervals (p = 0.050) and reduced SDNN values (p = 0.015). The higher the content of vitamin D, the greater increase in speed (r = 0.510), the higher the increase in projective performance (r = 0.485), and the smaller the increase in projective stress (r = −0.334). Significant relationships between the subjective characteristics of functional states and the vitamin D of participants have not been established. (4) Conclusion: With an increase in the severity of vitamin D deficiency in the blood, the adaptive capabilities of participants decrease during an expedition to the Arctic. Full article

With high health requirements for FIFO work at industry, workers may experience adverse changes in psychological well-being and health status. This makes it relevant when developing the job performance model to rely on considering not only the effectiveness by employees but also their psychophysiological “cost of activity”, which is not reflected in modern scientific research. This article theoretically substantiates and empirically develops a job performance typology of fly-in-fly-out workers at industrial enterprises by correlating three components: effectiveness, psychophysiological resources, and the way of accomplishing tasks. The study involved 359 fly-in-fly-out workers in oil and gas, diamond mining and construction industries with different duration of the fly-in period, operating in the South and the North of the Russian Federation. The research methods included questioning, psychophysiological instrumental testing, and psychological testing. Statistical processing was carried out using the methods of descriptive statistics, two-stage cluster analysis, and multivariate analysis of variance. As a result of the study, six types of job performance of fly-in-fly-out personnel of industrial enterprises were identified. The employees at industrial enterprises of all six types of job performance correspond to their position and perform the assigned tasks, the difference in them lies in the desire to show an average or the highest possible result, as well as how much internal resources the employee spends to achieve this result and how quickly he restores them, which is expressed in terms of his state and well-being. Based on the results of these connections, measures for personnel management for industrial enterprises were proposed. Full article

The study describes psychosocial risk factors at work in relation to the general functional state of a body, working capacity and stress among shift workers at a logging enterprise in the Far North. The study involved 153 loggers with a 14-day shift period. Research methods included the psychophysiological instrumental method (variocardiointervalometry) used to assess the general functional state of a body, M. Luscher’s color test to assess working capacity and stress and QNordic to assess psychosocial factors. Statistical analysis was performed using multiple stepwise regression analysis and frequency analysis. It was found that 71.1% of employees have a favorable general functional state of the body, 28.9%—unfavorable; the forest loggers who took part in the survey have a high level of working capacity and a low level of stress. It was substantiated that the general functional state of a body, stress and working capacity, measured by objective and subjective methods, are differentially interconnected with psychosocial factors at work. The general functional state of forest harvesting workers is influenced by factors of labor content, intensity and organization. The relationships with the immediate supervisor are important in order to increase the working capacity and efficiency of employees as well as their involvement in work. Full article

(1) Background: the research purpose is to identify and describe the general and different factors of adverse environmental impact on FIFO personnel at industrial enterprises at different levels of differential analysis of professional activity. (2) Methods: The research involved 359 employees of industrial enterprises with FIFO work organization. The study was carried out using a questionnaire, including a subjective assessment of the discomfort of three groups of negative environment impact factors to the FIFO personnel: climatic-geographical, industrial and social. (3) Results: The relationship between the increase in the degree of discomfort of production factors due to the in-fluence of climatic, geographical and social conditions has been established. With a various location of objects, the greatest discomfort is felt from the action of climatic and production factors; with varying degrees of group isolation and the shift period duration—all three groups, with the greatest influence of domestic and social; in various industries and enterprises—all three groups. (4) Conclusions: The differential analysis of the professional activities of FIFO personnel of industrial enterprises should be carried out at the following levels: the location of an industrial facility, the degree of group isolation, the duration of the shift period, the industry, the type of enterprise and the professional group.

(1) Background: the research purpose is to identify and describe the stress and working capacity dynamics of oil and gas fly-in-fly-out (FIFO) workers in the Arctic during the fly-in period using biochemical, psychophysiological and psychological methods with further analysis of the relationship between them using objective, subjective and projective indicators. (2) Methods: The research involved 70 oil and gas FIFO specialists in the Arctic. The study of stress and working capacity was carried out using biochemical (saliva analysis for cortisol), psychophysiological (complex visual–motor reaction and variational cardiointervalometry) and psychological (questionnaire “Well-being. Activity. Mood”, M. Luscher’s color test and the subjective control level methods. (3) Results: There is a similarity in the dynamic curves of oil and gas FIFO employees’ stress and working objective, subjective and projective indicators during the fly-in period. The maximum relationships number was obtained between objective cortisol indicators in saliva (stress), complex visual–motor response indicators (operator working capacity), variational cardiointervalometry (functionality level), and interpretation coefficients (working capacity, stress, vegetative balance) according to M. Luscher’s test. (4) Conclusions: The obtained results made it possible to explain the mechanisms underlying the previously developed FIFO workers’ adaptation strategies classification, in which emergency and economic adaptation strategies were identified.

The professional activity in shifts in the Arctic contributes to the development of unfavorable functional status and destructive personal qualities of workers, which leads to a decrease in the level of mental health and efficiency of labor activity. The reference to the risk-oriented approach is conditioned by the need to predict the professional efficiency of shift personnel. The purpose of this study is to determine the psychological risks of oil and gas workers with a shift work organization in the Arctic. The study involved 70 oil and gas workers. The research methods were used as follows: documentation study, work process monitoring, questionnaire survey, psychophysiological and psychological testing, and statistical analysis methods: descriptive statistics—conjugacy tables with calculation of Pearson’s criterion, two-stage cluster, dispersion, and discriminant analyzes. As a result of this research, it was established that oil and gas workers characterized by different combinations of character accentuations would have different psychological risks, and, consequently, different approaches to their psychological support are needed.
