Validation of the Spanish Version of the Eating Assessment Tool-10 (EAT-10spa) in Colombia. A Blinded Prospective Cohort Study

Abstract

Dysphagia might affect 12 % of the general population, and its complications include pneumonia, malnutrition, social isolation, and death. No validated Spanish symptom survey exists to quantify dysphagia symptoms among Latin Americans. Therefore, we performed a prospective cohort study in a tertiary care university hospital to validate the Spanish version of the 10-Item Eating-Assessment-Tool (EAT-10spa) for use in Colombia. After an interdisciplinary committee of five bilingual specialists evaluated the EAT-10spa (translated and validated in Spain) and deemed it appropriate for the Colombian culture, its feasibility, reliability, validity, sensitivity to change, and diagnostic capacity were evaluated. As a reference standard, we used the flexible endoscopic evaluation of swallowing with sensory testing and a standardized clinical evaluation. All assessments were blinded. In total, 133 subjects were included (52 % women, mean age 55 years) and completed the EAT-10spa (median completion time: 2 min [IQR 1–3 min]), 39 % of whom had an elementary-level education. Cronbach’s α coefficient: 0.91; test–retest intra-class correlation coefficient: 0.94. The Spearman’s correlation coefficient of the EAT-10spa with the 8-point penetration-aspiration scale was 0.54 (P < 0.001). The area under the receiver-operating-characteristic-curve (AUC-ROC) for dysphagia and aspiration were 0.79 (P < 0.001) and 0.81 (P < 0.001), respectively. The best cut-off points for dysphagia and aspiration were EAT-10spa ≥2 (sensitivity 93.6 %, specificity 36.4 %) and EAT-10spa ≥4 (sensitivity 94.3 %, specificity 49.5 %), respectively. A reduction in the EAT-10 ≥3 was the best cut-off point for a clinically significant improvement (AUC-ROC 0.83; P < 0.0001). The EAT-10spa showed excellent psychometric properties and discriminatory capacity for use in Colombia.
