The UGRS, originally validated in Western and Eastern cultures, had not been examined in a Iranian context. The research involved translating the UGRS into Persian, followed by a thorough psychometric evaluation involving 325 bereaved Persian-speaking adults. The Persian UGRS demonstrated strong internal consistency (Cronbach\u2019s alpha and McDonald\u2019s \u03c9 = 0.92) and test-retest reliability (ICC = 0.85). Confirmatory factor analyses supported a second-order hierarchical model of grief rumination. Concurrent validity was affirmed through significant correlations with depression, anxiety, prolonged grief, and PTSD. Known-groups validity highlighted higher rumination levels among individuals with lower education, those who lost close family members, and women. These findings underscore the Persian UGRS\u2019s reliability and validity, offering a robust tool for assessing grief-related rumination in the Iranian population.<\/jats:p>","DOI":"10.1177\/00302228241286923","type":"journal-article","created":{"date-parts":[[2024,9,25]],"date-time":"2024-09-25T20:12:39Z","timestamp":1727295159000},"page":"2610-2628","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Psychometric Properties of the Persian Version of Utrecht Grief Rumination Scale"],"prefix":"10.1177","volume":"93","author":[{"given":"Ahmad","family":"Ashouri","sequence":"first","affiliation":[{"name":"Iran University of Medical Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6994-3240","authenticated-orcid":false,"given":"Shahab","family":"Yousefi","sequence":"additional","affiliation":[{"name":"Iran University of Medical Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatemeh","family":"Abdoli","sequence":"additional","affiliation":[{"name":"Department of Clinical Psychology, Faculty of Psychology and Educational Science, Allameh Tabatabaei'i University, Tehran, Iran."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arezoo","family":"Nasirimoghadam","sequence":"additional","affiliation":[{"name":"Islamic Azad University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hajar","family":"Aliyaki","sequence":"additional","affiliation":[{"name":"Department of Clinical Psychology, Faculty of Psychology and Educational Science, Allameh Tabatabaei'i University, Tehran, Iran."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,9,25]]},"reference":[{"key":"e_1_3_6_2_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1478951524000348"},{"key":"e_1_3_6_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425787"},{"key":"e_1_3_6_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/07481187.2023.2272984"},{"key":"e_1_3_6_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/00302228231162730"},{"key":"e_1_3_6_6_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1478951523000202"},{"key":"e_1_3_6_7_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1352465807004079"},{"key":"e_1_3_6_8_1","doi-asserted-by":"publisher","DOI":"10.1037\/0003-066X.59.1.20"},{"key":"e_1_3_6_9_1","doi-asserted-by":"publisher","DOI":"10.4324\/9781315827506"},{"key":"e_1_3_6_10_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12888-018-1630-1"},{"key":"e_1_3_6_11_1","doi-asserted-by":"publisher","DOI":"10.1521\/ijct.2008.1.3.192"},{"key":"e_1_3_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2020.09.049"},{"key":"e_1_3_6_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.beth.2022.01.001"},{"key":"e_1_3_6_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/bjc.12067"},{"key":"e_1_3_6_15_1","doi-asserted-by":"publisher","DOI":"10.1080\/02682621.2017.1349291"},{"key":"e_1_3_6_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10862-013-9377-y"},{"issue":"5","key":"e_1_3_6_17_1","first-page":"369","article-title":"Waarom is dit mij overkomen?\u201d: Ontwikkeling en validatie van de Utrechtse Rouw Ruminatie Schaal","volume":"45","author":"Eisma M.
