Early evidence on the mental health of Ukrainian civilian and professional combatants during the Russian invasion.

A sizable portion of Ukrainian combatants reached cut-off levels for clinical symptoms of anxiety (44·4%), depression (43·3%), and insomnia (12·4%). Importantly, the mental health of Ukrainian combatants varied between professional soldiers and civilian combatants, as well as by gender, marital status, by whether or not they were located in Russian-occupied/active-combat areas, and dependent on whether they were personally involved in combat. This study provides early evidence on the mental health of Ukrainian combatants, pointing to their urgent need for mental health assistance in the ongoing war.
