Introduction. During long-term shift work, there is a cumulative effect of the adverse environment effects on the industrial enterprises’ personnel, which can be compensated by the adaptive qualities of workers. It requires clarification of how effective various combinations of conscious self-regulation of behaviour and character accentuation characteristics in shift workers at industrial enterprises can be in relation to the success of socio-environmental occupational adaptation.

The study purpose was to identify the success of socio-environmental occupational adaptation characteristics among shift personnel at industrial enterprises with different combinations of the severity of character accentuations and behaviour conscious self-regulation parameters.

Materials and methods. The study involved three hundred fourteen shift workers at various industrial enterprises. The assessment of the functional states in workers was assessed using instrumental methods and testing. Questionnaires were used to study the occupational effectiveness and safety. Character accentuations and behaviour conscious self-regulation characteristics were assessed using tests. Statistical methods are descriptive statistics, two-stage cluster and multivariate analyzes of variance.

Results. As a result of the study, shift workers at industrial enterprises were divided into four groups regarding the combination of conscious self-regulation and character accentuations. The successful socio-environmental occupational adaptation was found to be demonstrated by less accentuated shift workers with high self-regulation.

Limitations. The limitations of this study were the industrial enterprises choice of oil and gas production, diamond mining and construction as empirical objects, which requires consideration when extending the results to other samples. The methods selection for assessing the socio-environmental professional adaptation parameters of shift personnel is determined by the author’s concept.

Conclusion. The results and conclusions obtained make it possible to expand knowledge about the success in socio-environmental occupational adaptation in shift personnel at industrial enterprises and develop practical recommendations for their optimization. Due to the extreme conditions of the occupational environment, a larger number of shift workers with pronounced character accentuations are observed at northern sites, with a shift period lasting more than one month and, in the oil, and gas industry.
