The ongoing war in Ukraine significantly affects the mental and emotional well-being of its citizens. Consequently, there is an urgent need to explore the use of the resource psychotherapy model to develop effective support methods for trauma victims. The research aims to enrich the understanding of resource-based psychotherapy as an effective tool for supporting people who have experienced psychological trauma and improving their psychological well-being and quality of life. The analytical method, generalization, and systematization were used in this research. A clinical case of psychotherapy of a military man according to the 7-step model of working with the consequences of a psychotraumatic event is considered, which ultimately showed the effectiveness of its application. The study found that the resource psychotherapy model has significant potential for improving the psychological state of victims of trauma, as this approach allows the active use of internal resources of the individual to overcome the consequences of traumatic experiences and restore mental well-being. The results of the study indicate the effectiveness and deep potential of resource-based psychotherapy in working with people facing psychological trauma, helping them to build positive adaptation strategies and strengthen their psychological state. The results of this study may be useful for psychologists and psychotherapists working with people who have experienced traumatic experiences to improve the quality of psychological support and assistance to such people.
