However, the factor structure of PGD has been contested and few studies have tested competing models or assessed the item-level fit of PGD symptoms included in the DSM-5-TR using Item Response Theory (IRT). Therefore, this study addressed these gaps using IRT. The results indicated that a modified three-factor model of the PGD criteria demonstrated the best model fit. IRT analyses identified items in the PGD criteria provided little information or peak information at low-to-average levels of PGD. These findings underscore the importance of assessing item-level information to improve the DSM-5-TR PGD criteria and the need to replicate study results using IRT in a representative sample. These findings and future studies are vital to improve our measurement of PGD and advance the field for future iterations of the DSM.<\/jats:p>","DOI":"10.1177\/00302228261489676","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T14:38:59Z","timestamp":1790174339000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Item Response Theory to Evaluate Prolonged Grief Disorder in the DSM-5-TR Among Young Adults"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5535-0572","authenticated-orcid":false,"given":"Carol","family":"Fadalla","sequence":"first","affiliation":[{"name":"Texas Tech University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth","family":"McLean","sequence":"additional","affiliation":[{"name":"Texas Tech University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Littlefield","sequence":"additional","affiliation":[{"name":"Texas Tech University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zachary G.","family":"Baker","sequence":"additional","affiliation":[{"name":"Arizona State University, Phoenix, Arizona, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Singer","sequence":"additional","affiliation":[{"name":"Texas Tech University"},{"name":"Texas Tech University Health Sciences Center"},{"name":"exas Tech University Health Sciences Center"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"e_1_3_8_2_1","volume-title":"Categorical data analysis","author":"Agresti A.","year":"2013","unstructured":"Agresti A.
