The aim of this study was to validate the S-WDS for adult patients with EoE. Methods: Ninety-seven Swedish adult patients with EoE and 97 controls without dysphagia filled out the S-WDS, the Swedish Eosinophilic Esophagitis Activity Index (S-EEsAI) and a set of supplementary questions. The reliability of the S-WDS was evaluated using Cronbach\u2019s alpha, Pearson correlation of items and total score, and test\u2013retest analysis (n\u00a0=\u200929). Validity was investigated using Spearman correlations of the S-WDS items, S-EEsAI domains and a self-assessment score, and by investigating floor and ceiling effects. Results: The Cronbach\u2019s alpha of the S-WDS was 0.77 and all items demonstrated moderate to strong correlation to the S-WDS score (r\u00a0=\u20090.40\u20130.81) indicative of sufficient reliability of the instrument. In addition, the test\u2013retest results reflected excellent reliability with an intraclass correlation coefficient of 0.85 for the S-WDS score. Adequate validity of the instrument was demonstrated, the S-WDS score correlated moderately with the self-assessment score and with 4\/6 S-EEsAI domains, and strongly with the remaining two domains. Floor effects were more common for liquids and soft-textured foods and ceiling effects increased with increasing food consistency. The S-WDS scores of the patient group were significantly different from those of the nondysphagia control group (P\u00a0&amp;lt;\u20090.001). Conclusion: The S-WDS instrument is an appropriate and valid instrument for assessment of dysphagia in patients with EoE.<\/jats:p>","DOI":"10.1093\/dote\/doab097","type":"journal-article","created":{"date-parts":[[2022,1,23]],"date-time":"2022-01-23T08:21:57Z","timestamp":1642926117000},"source":"Crossref","is-referenced-by-count":5,"title":["Validation of the Swedish Watson Dysphagia Scale for adult patients with eosinophilic esophagitis"],"prefix":"10.1093","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2038-4286","authenticated-orcid":false,"given":"Sofie","family":"Albinsson","sequence":"first","affiliation":[{"name":"Department of Infectious Diseases , Institute of Biomedicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg , Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Tuomi","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology , Head and Neck Surgery, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg , Sweden"},{"name":"Department of Otorhinolaryngology , Head and Neck Surgery, Sahlgrenska University Hospital, Gothenburg, Region V\u00e4stra G\u00f6taland , Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Wenner\u00e5s","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases , Institute of Biomedicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg , Sweden"},{"name":"Department of Clinical Microbiology , Sahlgrenska University Hospital, Gothenburg, Region V\u00e4stra G\u00f6taland , Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helen","family":"Larsson","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology , Head and Neck Surgery, Institute of Clinical Sciences, Sahlgrenska Academy, University of Gothenburg, Gothenburg , Sweden"},{"name":"Department of Otorhinolaryngology , Head and Neck Surgery, NU Hospital Group, Trollh\u00e4ttan, Region V\u00e4stra G\u00f6taland , Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,1,22]]},"reference":[{"issue":"1","key":"2022071308253212000_ref1","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1016\/j.mcna.2018.08.009","article-title":"Eosinophilic esophagitis","volume":"103","author":"Reed","year":"2019","journal-title":"Med Clin North Am"},{"issue":"6","key":"2022071308253212000_ref2","doi-asserted-by":"crossref","first-page":"954","DOI":"10.1067\/mai.2001.119917","article-title":"Idiopathic eosinophilic esophagitis is associated with a T(H)2-type allergic inflammatory response","volume":"108","author":"Straumann","year":"2001","journal-title":"J Allergy Clin Immunol"},{"issue":"3","key":"2022071308253212000_ref3","doi-asserted-by":"crossref","first-page":"335","DOI":"10.1177\/2050640616689525","article-title":"Guidelines on eosinophilic esophagitis: evidence-based statements and recommendations for diagnosis and management in children and adults","volume":"5","author":"Lucendo","year":"2017","journal-title":"United Eur Gastroenterol J"},{"key":"2022071308253212000_ref4","article-title":"Patient-reported dysphagia in adults with eosinophilic esophagitis: translation and validation of the Swedish eosinophilic esophagitis activity index","author":"Albinsson","year":"2021","journal-title":"Dysphagia"},{"issue":"9","key":"2022071308253212000_ref5","doi-asserted-by":"crossref","DOI":"10.1093\/dote\/doy125","article-title":"Validation of instruments for the assessment of dysphagia due to malignancy of the esophagus","volume":"32","author":"Persson","year":"2019","journal-title":"Dis Esophagus"},{"issue":"12","key":"2022071308253212000_ref6","doi-asserted-by":"crossref","first-page":"3833","DOI":"10.1007\/s00405-015-3696-4","article-title":"Dysphagia and health-related quality of life in patients with eosinophilic esophagitis: a long-term follow-up","volume":"272","author":"Larsson","year":"2015","journal-title":"Eur Arch Otorhinolaryngol"},{"issue":"4","key":"2022071308253212000_ref7","doi-asserted-by":"crossref","first-page":"551","DOI":"10.1177\/0194599811409857","article-title":"Dysphagia and quality of life may improve with mometasone treatment in patients with eosinophilic esophagitis: a pilot study","volume":"145","author":"Bergquist","year":"2011","journal-title":"Otolaryngol Head Neck Surg"},{"key":"2022071308253212000_ref8","doi-asserted-by":"crossref","DOI":"10.1080\/00365521.2021.1906314","article-title":"Topically applied mometasone furoate improves dysphagia in adult eosinophilic esophagitis -
