dc.description.abstractObjective The 10-item Dysphagia in Multiple Sclerosis (DYMUS) questionnaire is a self-administered tool used to identify swallowing problems in adults with MS. The questionnaire was not validated against other existing questionnaires to assess its convergent validity. Moreover, its test-retest reliability was not measured previously. Therefore, the purpose of this study was to assess the factor analysis, internal consistency and test-retest reliability of the DYMUS, as well as its convergent validity against an established and validated questionnaire, the EAT-10. Method English-speaking adults with MS in New South Wales, Australia who were seen for routine medical check-ups were invited to complete two questionnaires across two phases. One hundred participants completed phase 1, while 55 completed phase 2. Statistical analyses were performed to investigate the psychometric properties of the DYMUS questionnaire. Results Internal consistency (Cronbach's Alpha) reduced the DYMUS questionnaire from ten to five items. The shortened version of the DYMUS showed high internal consistency (alpha = 0.904). It also showed satisfactory reproducibility, and adequate correlation with the 10-item Eating Assessment Tool (EAT-10).<h4>Conclusion</h4>Evaluation of the DYMUS resulted in a shortened version of the questionnaire with five questions related to dysphagia. This shortened version is considered an easy and useful tool in identifying patients with MS-related dysphagia.
