Abstract: Within the framework of this article, the authors present the results of studying group dynamic indicators during the corporate culture training. The object of the research is group dynamics as a set of processes occurring in a group of training participants. The subject of the research is the possibility of managing group dynamics of the student group through the corporate culture training. The rationale of the research is caused by the fact that there is a growing interest in trainings at high schools today as well as proved efficiency of trainings as an instrument of group dynamics management. Methods include content analysis, training, questionnaire techniques, observation. When processing research results, the authors have also applied descriptive analysis methods for calculating mean values and standard deviation based on trust-mistrust indicators, correlation-regression analysis, and variance analysis in assessing changes in group dynamics and corporate culture groups after the training. The study involved 78 students, 55 third- and fourth-year students who had attended training sessions and 23 second-year students who did not attend training sessions (69 females and 9 males). As a result of the study, the authors confirm their hypothesis that development of a united group of students in the course of the corporate culture training is possible only taking into account group dynamics factors. The scientific novelty of the research is caused by the authors' approach to the corporate culture development from the point of view of group dynamics. 

Abstract: The article analyzes the current approaches to evaluating efficiency of the training effects from the perspective of social and vocational psychology, and personality as the main object of influence of social-psychological trainings. The authors present the analysis of approaches to understanding efficiency of training effects by Yu. Zhukov, and L. Petrovskaya. They have also analyzed approaches to the evaluation of changes in psycho-impact of the training on the personality, interpersonal relations and professional competence described by such authors as: D. Kirkpatrick, and R. Bickley and D. Caple, A. Chanko, L. Petrovskaya and O. Pyatkova from the point of view of their relevance. Methods used by the authors during their research include content analysis of data from print and electronic sources of text data in empirical and practical studies of the authors concerning efficiency of the training impact of the socio-psychological training. The authors conclude that there are certain gaps in recording and interpreting personal impacts of the most popular short-term training programs. Based on the results of researches by O. Pyatkova and V. Kabrina the authors present a scheme of social and psychological assessment of stress-transformation of personality achieved in the process of implementing short-term training programs. The proposed scheme facilitates the interpretation of results of the training impact in terms of trans-communicative approach to the evaluation of short-term programs at various stages of the training cycle.
