This cross\u2010sectional study recruited internet users from advertisements on social media. Levels of rumination, Depression, Anxiety and Stress Scale (DASS), Impact of Event Scale\u2010Revised (IES\u2010R), time spent on news of the war, and related demographic variables were collected. The reliability and construct validity of rumination were estimated. Potential factors associated with the level of rumination were identified using univariate linear regression analysis, and further entered into a stepwise multivariate linear regression model to identify independent factors. Due to the non\u2010normality of distribution, multivariate linear regression with 5000 bootstrap samples was used to verify the results. A total of 1438 participants were included in the analysis, of whom 1053 lived in Poland and 385 lived in Ukraine. The questionnaires on rumination were verified to have satisfactory reliability and validity. After analysis with stepwise and bootstrap regression, older age, female gender, higher DASS and IES\u2010R scores, and longer time spent on news of the war were significantly associated with higher levels of rumination for both people living in Poland and Ukraine. Lower self\u2010rated health status, history of chronic medical illness and coronavirus disease 2019 infection were also positively associated with rumination for people living in Poland. We identified several factors associated with the level of rumination about the Russo\u2010Ukrainian War. Further investigations are warranted to understand how rumination affects individuals\u2019 lives during crises such as war.<\/jats:p>","DOI":"10.1002\/kjm2.12711","type":"journal-article","created":{"date-parts":[[2023,6,8]],"date-time":"2023-06-08T04:11:13Z","timestamp":1686197473000},"page":"943-953","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Rumination about the <scp>Russo\u2010Ukrainian War<\/scp> and its related factors among individuals in Poland and Ukraine"],"prefix":"10.1002","volume":"39","author":[{"given":"Dian\u2010Jeng","family":"Li","sequence":"first","affiliation":[{"name":"Graduate Institute of Medicine and School of Medicine, College of Medicine Kaohsiung Medical University  Kaohsiung Taiwan"},{"name":"Department of Addiction Science Kaohsiung Municipal Kai\u2010Syuan Psychiatric Hospital  Kaohsiung Taiwan"},{"name":"Department of Nursing Meiho University  Pingtung Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agata","family":"Chudzicka\u2010Czupa\u0142a","sequence":"additional","affiliation":[{"name":"Faculty of Psychology SWPS University of Social Sciences and Humanities  Katowice Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateusz","family":"Paliga","sequence":"additional","affiliation":[{"name":"Faculty of Social Sciences, Institute of Psychology University of Silesia in Katowice  Katowice Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadiya","family":"Hapon","sequence":"additional","affiliation":[{"name":"Department of Psychology, Faculty of Philosophy Ivan Franko National University in Lviv  Lviv Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liudmyla","family":"Karamushka","sequence":"additional","affiliation":[{"name":"G.
