The article is devoted to the analysis of students' crisis communication in the context of their adaptation to the conditions of education during the war. War must be seen in the context of the problem of collective action (and therefore of collective trauma) because it consists of many elements necessary for coalitional aggression (both offensive and defensive). If the war has been going on for a long time, and the current Russian-Ukrainian one has been almost 10 years old, and at the same time it has been full-scale for more than two years, which is long enough in the context of analyzing the impact of various wars on the psychological state of people, in particular young people, students, it makes sense to talk about the need to adapt to the conditions military extremism and the development of effective communication methods that contribute to this adaptation. The purpose of this article is to study the peculiarities of crisis communication in the context of students' adaptation to studying in war conditions. We diagnosed the severity of PTSD symptoms in combatants using the PCL-M (F. Weathers), PCL-5 (T. M. Keane) PTSD questionnaires. The peculiarities of personal adaptation to the conditions of long wars, key aspects of crisis communication during extreme events, concepts of stress and trauma are determined. It has been proven that students are mostly characterized by a sufficient level of adaptability, their PTSD symptoms are mainly represented by intrusions and least of all by avoidance, under such conditions it is very necessary for them to develop the skills of effective crisis communication. In times of crisis, potential helpers take several considerations into account before providing assistance to a person. First, the situation is assessed: if the situation is perceived as serious and dangerous, people are more willing to help. Second, people have to decide how to help and how much of their own resources to spend on helping. Both processes (assessing the situation and choosing a course of action) can be supported by crisis communication, which, as a rule, is aimed at preventing or reducing the negative consequences of the crisis. However, people are generally not passive followers of crisis communication.
