摘要
BackgroundThe Eating Assessment Tool is a self-rating questionnaire developed to assess symptom severity and treatment efficacy in swallowing disorders. The aim of this study was to investigate the structural validity of the Eating Assessment Tool and whether individual item scores differed between dysphagia secondary to neurological and structural/esophageal disorders, respectively.MethodsThis is a prospective cross-sectional questionnaire study. In total, 200 community-dwelling adults with suspected dysphagia referred for fiberoptic endoscopic examination of swallowing at Karolinska University Hospital, Stockholm, Sweden, completed the S-EAT-10. Patients' medical charts were reviewed in order to establish the type of dysphagia. Principal axis factoring was conducted to examine structural validity, and Mann-Whitney U tests were used to study differences in the S-EAT-10 score patterns between different types of dysphagia.ResultsOne single factor explained 54% of the total variance in EAT-10 item scores. All ten items loaded substantially or strongly on this factor, supporting the single-factor solution (Cronbach's alpha=0.90). Structural/esophageal dysphagia was associated with higher scores on six items and with a higher total EAT-10 score.ConclusionsThe EAT-10 yields a unidimensional index of symptom severity in patients with dysphagia. Individual item scores reflect typical symptoms in neurogenic and structural/esophageal dysphagia, supporting its clinical relevance.
