Reliability and Validity of the Turkish Eating Assessment Tool (T-EAT-10)


The purpose of this study was to test the reliability and validity of the Turkish Eating Assessment Tool (T-EAT-10) among patients with swallowing disorders. One hundred and five patients completed the T-EAT-10 and Functional Oral Intake Scale (FOIS). The internal consistency, test–retest reliability, and criterion validity of T-EAT-10 were investigated. The internal consistency was assessed using Cronbach’s alpha. Intraclass correlation coefficient (ICC) value with 95 % confidence intervals was calculated for test–retest reliability. The criterion validity of the T-EAT-10 was determined by assessing the correlation between T-EAT-10 and FOIS. All the patients in the study completed the T-EAT-10 without assistance. The mean time to complete the instrument was 1.8 ± 0.9 min. The internal consistency of the T-EAT-10 was found to be high with 0.90 Cronbach’s alpha for test and 0.91 Cronbach’s alpha for retest reproducibility. No difference between the test and retest scores of the T-EAT-10 was found (p = 0.14). A negative, moderate correlation between T-EAT-10 and FOIS was detected (r = −0.365, p < 0.001). The T-EAT-10 is a reliable and valid symptom-specific outcome tool for dysphagia in adult Turkish patients. It can be used in clinical practice and research.
