Abstract
BackgroundDysphagia is a health concern that causes severe complications and affects the life quality of the older population. This study aimed to determine the diagnostic performance of the Eating Assessment Tool (EAT)-2 compared with the EAT-10 and the Water Swallow Test (WST) in screening for dysphagia. MethodsA cross-sectional study was conducted among 5,090 community-dwelling older adults. Dysphagia was evaluated using both a subjective measure, the 10-item EAT (EAT-10) and an objective measure, the WST. The kappa index in pairs were analyzed. The validity and reliability of EAT-2 were also assessed. ResultsThe sensitivity and specificity of the EAT-2 were 96.3 % and 94.8 %, respectively. The kappa index between the EAT-2 and EAT-10 was 0.64, whereas it was 0.11 between the EAT-10 and WST. ConclusionsThe EAT-2 was a simpler screening tool for dysphagia. Combining the subjective questionnaire (EAT-10 or EAT-2) and the objective test (WST) is recommended.
