Validation of the Swedish translation of eating assessment tool (S-EAT-10)

Conclusion The Swedish Eating Assessment Tool (S-EAT-10) is a reliable and valid self-administered tool in assessment of dysphagia in adult Swedish patients with high internal consistency, reliability, and discriminative validity. The normative data show that a score of 3 or more is abnormal. S-EAT-10 is recommended to be used in preliminary diagnostics of dysphagia. Objective To translate and adapt the EAT-10 for use in the Swedish patient population, and to present norms and measures of discriminative validity and reliability of a Swedish version of the Eating Assessment Tool-10 (S-EAT-10). Methods Prospective consecutive clinical study. In total, 134 community-dwelling adult respondents/controls without dysphagia completed the S-EAT-10, as did 119 patients referred for fiberendoscopic evaluation of swallowing at Karolinska University Hospital, Stockholm, Sweden. Patient vs control status was used as the criterion for discriminative validity assessment by logistic regression analysis. Results The mean S-EAT-10 score was 0.2 (range=0-3) for controls and 18 (range=0-38) for patients. Based on a cut-off score of 3 which was considered to be reflective of abnormalities, sensitivity was 98.5% and specificity 94.1%. Internal consistency reliability was high (Cronbach's alpha=0.88), as was test-re-test reliability (ICC=0.90).
