Introduction. The result of overcoming the consequences of the impact of the stressors of the combat situation and military professional activities by servicemen can be, along with negative ones, positive psychological changes that manifest themselves in changes in at least three areas: a) self-perception, b) philosophy and values of life, c) relationships with others, which we conceptualize as post-experience growth (PEG). In the course of psychological recovery, rehabilitation, and reintegration of servicemen with the aim of returning them to the conditions of everyday life, positive psychological changes are an important personal resource that is often used by psychologists when working with this category of people. In this context, there is a need to determine not only the presence of signs of positive psychological changes, but also the level of their manifestation, which will help to form an individual program for the cultivation of PEG, taking into account the psychological characteristics of the servicemen – combatants. Purpose. An empirical study of the multilevel manifestation of post-experience growth in servicemen - combatants and its group characteristics. Methods: The study used general scientific (measurement, comparison, analysis, synthesis, generalization and interpretation) and special (statistical, correlation, ranking, grouping, factor analysis) methods were used. Originality. The scientific novelty of the study is that the article is the first to empirically investigate the gradation of indicators of the general level of PEG on a sample of Ukrainian servicemen - combatants and to identify generalized psychological characteristics of this category of persons by the levels of PEG manifestation. Determining the levels of development of PEG and their group characteristics is important for taking into account the individual psychological characteristics of combatants in the process of their psychological recovery, rehabilitation and reintegration. The results of the study can be used during the further empirical study of the post-experience growth of military personnel participating in combat operations. Conclusion. In a sample of Ukrainian military personnel participating in combat operations, we identified four levels of PEG manifestation and their corresponding numerical indicators: 1st - high level (92.0-125.0 points); 2nd - above average level (51.0-76.0); 3rd - below average level (77.0-91.0); 4th - low level (from 0 to 50.0 points). Each of these levels has its own content in the form of group features that include personal determinants of the development of PEG, namely friendliness, conscientiousness, openness to new experiences, resilience, and self-efficacy. The latter two factors are important determinants of PEG at all levels of its manifestation. The group of servicemen with the 1st (high) level of development of PEG is characterized by high rates of resilience and self-efficacy, an increase in the importance of openness to new experiences, and a decrease in friendliness and conscientiousness. This group has the highest percentage of servicemen released from forced isolation (captivity). The group with the 2nd (above average) level is characterized by a sufficient balance between the four determinants - friendliness, conscientiousness, resilience and self-efficacy. This group includes about 40% of the respondents. The group characteristics of the 3rd (below average) level are a significant impact on the PEG of friendliness, average indicators of resistance and conscientiousness, insufficient manifestation of self-efficacy, the influence of which is also reduced. This group includes about 25% of the subjects. The group of servicemen with the 4th (low) level of development of the PEG is also characterized by a low level of self-efficacy and openness to new experiences, but has a sufficient level of resistance. At the same time, resilience, conscientiousness, and self-efficacy have the greatest impact on the further development of positive psychological changes. This group has the highest percentage of servicemen who recover after being withdrawn from the areas of assigned missions.

У статті досліджуються рівні прояву та групові ознаки постдосвідного зростання військовослужбовців – учасників бойових дій, як результату позитивних психологічних змін особистості внаслідок переживання травматичних і стресових подій. У ході емпіричного дослідження запропоновано чотирирівневу градацію прояву потсдосвідного зростання з визначенням відповідних їм групових ознак.
