In the dissertation the solution of the problem of combat psychological traumatization of the soldiers of the National guard of Ukraine (NGU) is proposed, which is to elaborate its theoretical and methodological principles, substantiate the empirical model of combat psychological traumatization of the personnel of NGU, determine the mechanisms of formation of the stability of the military service of the NGU to the psychological trauma of the combat experience, typing military psychological traumatization at NGU servicemen at different levels of psychotravel combat experience, the development of psychometric tools for assessing the psychological traumatization of combat experience and the stability of NGU servicemen to psychological traumatization, offering a comprehensive program for the prevention of combat psychological traumatization of NGU servicemen and the implementation of regulatory and legal principles for its implementation. The types of adaptation of NGU servicemen to the stressful conditions of performing military-combat tasks (MCT), self-regulation and value-semantic sphere of personality with various features of post-traumatic stress disorder (PTSD) are determined. It is proved that among the NGU servicemen there are four types of personality adaptations to stay in the anti-terrorist operation (ATO): «predicts danger», «open to danger», «assumes the role of victim», «hides his fear». The types of combat psychological traumatization of the personality of NGU servicemen with different levels of traumatic experience of combat experience are ascertained: ascending (high PTSD indicators) and downward (low PTSD indicators). It is determined that the NGU servicemen of the descending type, in contrast to the ascending type, perceive themselves more closely involved in society's life, are aware of the meaning of their own lives, consider it possible to control it, are confident in themselves, their capabilities, are satisfied with their own abilities, knowledge, abilities, skills, confident in their significance and its impact on the environment; aspire to certainty; volitional. It is revealed that structural changes in personality that occur in NGU troops descending type with the acquisition of combat experience in the ATO are determined by the experience gained from their professional team, which is the basis for training personnel to act in the ATO. For the NGU servicemen of the upward type, the structure of personality change with the accumulation of combat experience is due to their distancing from dangerous situations, the avoidance of active opposition to it, the increase of isolation, the notions of the uniqueness of their own experience, and the consolidation of negative self-determination. The automated psychodiagnostic complex «Psychological traumatization of personality» has 20 methodological forms (of which two are author's) and a projective color test of retrospective diagnostics of mental states. The complex provides 8 standard recommendations on the possibility of involving a serviceman of NGU to participate in ATO, the need to apply individual measures for psychological prevention.
The comprehensive program for the prevention of psychological traumatization of the personality in NGU troops covers the whole process of psychological support for their military and combat activity. This program may be adapted for further use in other central executive bodies, in particular in the National Police, the State Emergency Situations Service of Ukraine, the State Border Guard Service of Ukraine and other bodies for carrying out psychological rehabilitation of combatants. The results of the study have been embodied both in the preparation of statutory legal acts on the problems of psychological support and in the practical activities of the service of psychological support of the NGU.
