The aim of the present study was to investigate whether there are differences in terms stress, anxiety and depression depending on gender and implication level in the war in a sample of 526 Ukrainian teachers (85% women, with a mean age of 39.74, SD = 12.51 and having an average experience of teaching of 16.98 years, SD = 12.30). In order to measure stress, the short version of Perceived Stress Scale (PSS-4; Cohen et al., 1999) was used, and the 4-item version of Patient Health Questionnaire (PHQ-4; Kroenke et al., 2009) was used to measure participants’ depression and anxiety. All scales were filled out on-line using Quick survey platform. The independent t-test showed that women had higher levels of stress, anxiety and depression than men. In terms of implication status, results showed that participants whose relatives or close friends were involved in the war reported higher levels of stress, anxiety, and depression. Additionally, participants whose relatives or close friends were injured because of the war and participants whose relatives or close friends left Ukraine because of the war reported higher levels of stress, and anxiety. Moreover, there were no differences in terms of stress, depression and anxiety between the participants whose relatives or close friends died because of war and the participants whose relatives or close friends did not die because of the war. In conclusion, the results of the present study highlighted the differences in terms of mental health issues such as anxiety, stress and depression based on gender and the status of participants related to the implication in the Russian-Ukrainian war. Moreover, it provided new evidence on the psychological effects of the war. More specifically, we added new evidence on the psychological effects of the war on Ukrainians living in Ukraine since the war started until October-November 2022.
