The article discusses modern approaches to defining the concept of social and psychological climate. It has been established that in the conditions of military tension, the socio-psychological state of a person undergoes a destructive effect on the personality, which can be accompanied by long-term depression, anxiety disorders, the formation of post-traumatic stress syndrome, a decrease in work capacity, and a lack of interest in professional development and growth.The main approaches to defining the concepts of «influence» and «informational social influence» have been analyzed. A theoretical analysis of the concept as a process and result of an individual’s change in the behavior of another person, his attitudes, intentions, ideas, assessments, etc. in the process of interaction with him, was carried out. And the ways of using informational social influence in the context of the constructive and destructive effect of informational social influence on the individual in the conditions of war are analyzed.It has been established that informational influence can be manipulative in nature, which in turn will reflect on the mental, social and psychological well-being of Ukrainians.The mechanism of the influence of information manipulation, which can manifest itself in the form of propaganda, provocation, disinformation, intimidation, is revealed, and the place and role of constructive communication in the process of counteracting manipulative influence is defined. A theoretical analysis of the concept of «isolation» was carried out. It was determined that this is a protective mechanism that removes associative connections when the threat of danger is perceived.It was established that the social isolation of the individual in the collective makes support, empathy, and mutual understanding impossible in critical situations and in situations of uncertainty. And this, in turn, can increase the feeling of constant danger, excessive excitement, panic attacks, problems in relationships, the inability to express and show one’s feelings and experiences. On the basis of theoretical analysis, it was determined that the role of the leader is actualized in the conditions of martial law, because the situation that has developed requires him to be flexible in thinking and speed of decision-making, objectivity of reactions to external challenges in conditions of changeable situations and limited resources.We see the prospects for further research in the diagnosis of the current state of the social and psychological climate in the collectives of educational institutions, and in the search for optimal ways to solve the problem.The role of the team and the leader in the formation of a favorable social and psychological climate is characterized.
