However, in clinical research patients can be overwhelmed with multiple questionnaires. We recently developed the 7\u2010item brief QOD\u2010NS (B\u2010QOD). Our objective was to evaluate the psychometric properties of the B\u2010QOD in both the development (D) sample, and in a separate replication (R) sample.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Testing on D (<jats:italic>n<\/jats:italic>\u00a0=\u00a0203) and R (<jats:italic>n<\/jats:italic>\u00a0=\u00a0281) samples included initial exploratory factor analysis (EFA), followed by internal reliability, information loss, and confirmatory factor analysis (CFA). Finally, incremental predictive utility analysis (IPUA) was performed by correlating the B\u2010QOD with the 22\u2010item Sino\u2010Nasal Outcome Test (SNOT\u201022) survey.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>EFAs of both D and R demonstrated an underlying single\u2010factor structure (eigenvalue\u00a0=\u00a04.17 and 3.57, respectively) with comparable loading factors (<jats:italic>R<\/jats:italic>\u00a0&gt;\u00a00.30 for both). B\u2010QOD also had good internal reliability in both D and R (Cronbach's alpha\u00a0=\u00a00.88 and 0.83, respectively). Also, there is minimal information loss with B\u2010QOD compared to QOD\u2010NS in both D and R (<jats:italic>R<\/jats:italic>\u00a0=\u00a00.98 and 0.96, respectively). CFA indicates that the B\u2010QOD single\u2010factor model has good overall fit as measured by the Comparative Fit Index (CFI) and the Standardized Root Mean Squared Residuals (SRMSR) in the D and R samples (CFI\u00a0=\u00a00.99 and 0.97; SRMSR\u00a0=\u00a00.035 and 0.053). IPUA shows that the QOD\u2010NS offers no additional predictive benefit of SNOT\u201022 scores when compared with B\u2010QOD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The 7\u2010item B\u2010QOD captures a structurally coherent and reliable single dimension, with minimal information loss and excellent external predictive utility when compared to the QOD\u2010NS.<\/jats:p><\/jats:sec>","DOI":"10.1002\/alr.22800","type":"journal-article","created":{"date-parts":[[2021,4,17]],"date-time":"2021-04-17T18:12:38Z","timestamp":1618683158000},"page":"1436-1442","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Psychometric properties of the brief version of the questionnaire of olfactory disorders in patients with chronic rhinosinusitis"],"prefix":"10.1002","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8766-1626","authenticated-orcid":false,"given":"Jose L.","family":"Mattos","sequence":"first","affiliation":[{"name":"Division of Rhinology and Sinus Surgery Department of Otolaryngology\u2013Head and Neck Surgery University of Virginia  Charlottesville Virginia USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Todd E.","family":"Bodner","sequence":"additional","affiliation":[{"name":"Department of Psychology Portland State University  Portland Oregon USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jess C.","family":"Mace","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Oregon Health and Science University  Portland Oregon USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodney J.","family":"Schlosser","sequence":"additional","affiliation":[{"name":"Division of Rhinology and Sinus Surgery Department of Otolaryngology\u2013Head and Neck Surgery Medical University of South Carolina  Charleston South Carolina USA"},{"name":"Department of Surgery Ralph H.
