Mental Health and well-being During the COVID-19 Pandemic and After the Russian Invasion of Ukraine.

The study compared the mental health of university students during the COVID-19 pandemic and the Russian invasion of Ukraine. A repeated online cross-sectional study was performed twice among university students in Ukraine: in November 2020 (Pre-war sample, n = 752) and September-October 2022 (During-war sample, n = 862). The survey measured life satisfaction (SWLS), perceived stress (PSS-10), anxiety (GAD-7), and depression (PHQ-9). Stress, anxiety, and life satisfaction levels were similar during the war and pandemic, while symptoms of depression decreased during the war, compared to the pandemic. Network analysis showed that anxiety has a crucial effect on depression and stress, and stress is most closely related to life satisfaction. The association of life satisfaction with anxiety and depression disappeared in wartime, in contrast to the pandemic. The priority of prevention and intervention programs in wartime Ukraine should focus on anxiety as the most influential factor in other mental health and well-being problems. The results showed high resistance and adaptation to war conditions among university students in Ukraine.
