Additionally, the prevalence and levels of embitterment among the participants were assessed. This cross\u2010sectional methodological study included 575 participants. Following a rigorous forward\u2010backward translation process, the PTED\u201021 was adapted into Turkish. Reliability was assessed using Cronbach's alpha and split\u2010half reliability coefficients. To evaluate construct validity and identify the factor structure, exploratory factor analysis (EFA) was performed using principal component analysis with varimax rotation. Reliability analysis yielded a Cronbach's alpha of 0.960 and a Spearman\u2013Brown coefficient of 0.961. The Kaiser\u2013Meyer\u2013Olkin value was 0.958, and Bartlett's test of sphericity was statistically significant\n                    <jats:italic>(p\u2009&lt;\u20090.001)<\/jats:italic>\n                    . Factor analysis revealed that the Turkish PTED\u201021 consists of a three\u2010factor structure, explaining 67.49% of the total variance. The Turkish version of the PTED\u201021 is a valid and reliable instrument for assessing embitterment. Its clinical application may significantly enhance the diagnostic assessment of embitterment in Turkish\u2010speaking populations.\n                  <\/jats:p>","DOI":"10.1002\/cpp.70306","type":"journal-article","created":{"date-parts":[[2026,7,11]],"date-time":"2026-07-11T10:06:02Z","timestamp":1783764362000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Validation Study of the Turkish Version of the Post\u2010Traumatic\u2010Embitterment\u2010Disorder 21\u2010Item Scale"],"prefix":"10.1002","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1883-0761","authenticated-orcid":false,"given":"Zeynep","family":"A\u015fik","sequence":"first","affiliation":[{"name":"Department of Family Medicine Adana City Training and Research Hospital  Adana Turkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6628-8954","authenticated-orcid":false,"given":"Muhte\u015fem Erol","family":"Yayla","sequence":"additional","affiliation":[{"name":"Department of Family Medicine Adana City Training and Research Hospital  Adana Turkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,11]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40653\u2010021\u201000407\u20104"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.5455\/bcp.20151205113132"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.59075\/k23ttj75"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psychres.2014.03.032"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.18401\/2014.4.1.4"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.3346\/jkms.2023.38.e15"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.30773\/pi.2023.0299"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.140.1.105"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1159\/000070783"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1159\/000511468"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/cpp.610"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12888\u2010023\u201004642\u2010x"},{"key":"e_1_2_12_14_1","unstructured":"Ozdemir V.2021.The Investigation of Childhood Trauma and Post Traumatic Embitterment Level in Travesties: A Comparative Study [Master's Thesis Istanbul Gelisim University].
