AbstractWhile the literature on well‐being and stress following natural disasters is well‐developed, it is less so when it comes to ongoing war experiences. Between September and October of 2022, 223 Ukraine‐based civilian adults (156 women and 67 men) completed a survey measuring symptoms of post‐traumatic stress disorder (PTSD), peritraumatic experiences, paranoia, quality of life, death anxiety, anxiety about weapons of mass destruction and depression (i.e. assumed ‘war consequence’ factors), as well as perceived social support, resilience, loneliness and expected military support from the West (i.e. assumed ‘buffer’ factors). Our exploratory structural equation model (SEM) suggests that Perceived Social Support predicted fewer PTSD Symptoms and more Peritraumatic Experiences. The regression modelling, however, shows that Perceived Social Support was also positively correlated with Peritraumatic Experiences. Highlighting the need for a civilian war stress buffer disruption theory, we argue that when composed of one's circle of family and friends, social support could likely mean greater exposure to war stressors through the mutual sharing of ongoing war experiences with no end in sight. Such a possible war stress sharing deterioration effect would imply that Perceived Social Support may compound peritraumatic distress if the support in question is offered by those facing the same grim reality.
