Introduction. The current stage of the development of society is characterized by an avalanche-like increase in information, which, due to the continuous and rapidly growing pace, has acquired the character of the information industry. Currently, the problem of developing and using information systems in those areas of activity that are related to human health, especially in the areas of psychosocial status of a person who was under the negative influence of stressogenic factors caused by the state of war, is gaining relevance. Therefore, the development of information technology, which includes methods of operative diagnosis of the psychological state of a person, methods of qualifying corrective and rehabilitation measures with the involvement of the willpower of the victims, taking into account their characterological properties and the strength of the personal "I", are of great importance. Providing psychological support to persons who have been under the negative influence of psychogenic factors is an urgent and rather complex problem. We consider it expedient to involve the means of modern computer technologies in its solution. The purpose of the paper is to develop a computer decision-making support system for the rehabilitation of the psychosocial state of health of a person who was under the negative influence of psychogenic factors, taking into account personal character traits. Results. A hierarchical structure of health assessment technology was developed, taking into account personal characterological properties. On the basis of a hierarchical approach, an information-technological structure of classification and evaluation of human character properties has been developed. A program algorithm for the application of rehabilitation measures depending on the strength of manifestation of characterological properties of the individual has been synthesized. A computer system was developed to support rehabilitation decision-making by a person with psychological problems, taking into account his personal character traits. Conclusions. The developed classification of the working information array, which is carried out using a hierarchical approach, systematizes and transforms a huge amount of unordered data related to the psychological component, taking into account the character, into an information product convenient for further computer-technological transformations. The developed information technology, implemented in a computer decision support system, is a constructive tool for increasing the accessibility and efficiency of providing the necessary specific information to the user when choosing rehabilitation measures, taking into account the personal characteristics of his character. Taking into account the characterological components of mental status in the developed computer support system for making rehabilitation decisions by persons who were under the influence of psychological overstrain in connection with martial law increases the purposefulness of recommendations in the case of independent selection of health measures. Keywords: human character, hierarchical modeling, negative psychogenic factors, mental health, computer decision support system.
