A total of 141 adults who lost a significant person during the COVID-19 pandemic completed questionnaires at two time points, assessing perceived restrictions, psychological impact, trauma, anxiety, depression, prolonged grief, and rumination. Results showed that high levels of restrictions\u2019 psychological impact were associated with elevated symptoms of trauma, anxiety, depression, and prolonged grief. Although only 8.5% met criteria for Prolonged Grief Disorder (PGD), trauma symptoms remained prevalent in 70.9% nearly a year after the loss. Mediation analyses showed that grief-specific rumination statistically accounted for the association between the psychological impact of restrictions and prolonged grief symptoms. The findings underscore the disruptive effects of pandemic-related restrictions on grieving processes and suggest that interventions targeting rumination may reduce long-term psychological distress in bereaved individuals.<\/jats:p>","DOI":"10.1177\/00302228261443784","type":"journal-article","created":{"date-parts":[[2026,5,5]],"date-time":"2026-05-05T03:30:01Z","timestamp":1777951801000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Restricted End-of-Life Care and Mourning During COVID-19: A Longitudinal Study on Grief, Mental Health, and Rumination"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2883-415X","authenticated-orcid":false,"given":"Alexandra","family":"Coelho","sequence":"first","affiliation":[{"name":"APPsyCI\u2014Applied Psychology Research Center Capabilities &amp; Inclusion, ISPA\u2014Instituto Universit\u00e1rio, Lisbon, Portugal"},{"name":"University of Lisbon"},{"name":"InLuto \u2013 Associa\u00e7\u00e3o Portuguesa de Cuidados Integrados no Luto"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sara","family":"Albuquerque","sequence":"additional","affiliation":[{"name":"HEI\u2010Lab: Digital Human\u2010Environment Interaction Labs, Lus\u00f3fona University, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mayra","family":"Delalibera","sequence":"additional","affiliation":[{"name":"Faculty of Medicine of the University of Coimbra"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o","family":"Batista","sequence":"additional","affiliation":[{"name":"Department of Education and Psychology of the School of Human and Social Sciences, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), Vila Real, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,5,4]]},"reference":[{"key":"e_1_3_5_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyt.2021.638874"},{"key":"e_1_3_5_3_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association.
