The objective was to investigate the psychometric properties of the Dysphagia in Multiple Sclerosis (DYMUS) questionnaire and examine whether item reduction improves them.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The participants, 153 patients with MS and 104 healthy controls, completed the DYMUS and the Eating Assessment Tool 10 (EAT\u201010). The study consisted of factor, reliability and validity analysis of DYMUS, and item reduction, reliability, validity analysis and normative data generation for the modified DYMUS (mod\u2010DYMUS).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The internal consistency of DYMUS was excellent (Cronbach\u2019s alpha 0.886). Test\u2013retest reliability was good for all the items. Factor and reliability analysis, along with other psychometric features, supported item reduction. The mod\u2010DYMUS (consisting of items 1 and 3\u20137) showed improved internal consistency (Cronbach\u2019s alpha 0.903) and inter\u2010item correlation coefficients (0.558\u20130.657), good test\u2013retest reliability, excellent criterion validity and improved convergent validity. Patients had significantly higher mean mod\u2010DYMUS score than controls (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001), and dysphagic patients (EAT\u201010\u00a0\u2265\u00a03) had significantly higher mod\u2010DYMUS than non\u2010dysphagic patients (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001). A strong positive and significant correlation was noted between the mod\u2010DYMUS and the EAT\u201010 (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001). A mod\u2010DYMUS score of 1 or higher indicates dysphagia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Item reduction improves the psychometric properties of DYMUS. The mod\u2010DYMUS is a valid, reliable, low\u2010burden, screening tool for the detection of dysphagia in MS, which can enhance personalized assessment and guide management decisions that better
