Under conditions of a full-scale war, the population of Ukraine is experiencing intense stress exposure, which may have a serious negative impact on mental health [1, p. 555; 2, p. 1280236]. The effects of war-related social stress are particularly dangerous for psychologically vulnerable groups, including medical university students [3, p. 437; 4, p. 304]. Education at a medical university is associated with a significant informational and stress load due to increased academic demands, high responsibility, competition, and the need for substantial changes in lifestyle patterns [5, p. e41185; 6, p. 772; 7, p. e41185]. The risk of developing psychopathological reactions as a result of the psychotraumatic effects of stress is determined not only by the intensity and duration of stress exposure but also by the effectiveness of an individual’s psychological defense mechanisms [8, p. 39; 9, p. 59]. In recent years, particular attention has been paid to the psychological phenomena of hardiness and resilience, the development of which is considered a promising means of counteracting the destructive effects of psychoemotional stress [10, p. 1458049; 11, p. 516; 12, p. 223]. The aim of this study was to examine the characteristics of hardiness and resilience in medical university students during wartime and to analyze the relationship between these psychological phenomena and the severity of depressive, anxiety, and stress-related disorders. In compliance with the requirements of biomedical ethics and based on informed consent, 207 full-time students (53 males and 154 females) of National Pirogov Memorial Medical University, Vinnytsia, majoring in “Medicine,” “Pediatrics,” and “Medical Psychology,” were examined during March-April 2025. The mean age of the participants was 20.0 ± 1.6 years. The study protocols were approved by the Bioethics Committee of Vinnytsia National Pirogov Memorial Medical University (Protocol No. 11 dated 2024/11/21). The assessment was conducted using an original questionnaire, Ukrainian-language versions of the Depression, Anxiety and Stress Scale (DASS-21) [13], the short form of Maddi’s
