Abstract

The eating assessment tool (EAT-10) is a self-reported questionnaire to assess the patient’s perception of swallowing difficulties. The aim of this study was to cross-culturally adapt and determine validity and reliability of the Persian version of the EAT-10 (P-EAT-10) in patients with oropharyngeal dysphagia. The EAT-10 was translated into Persian language and cross-culturally adapted. One hundred patients with dysphagia (mean age ± SD = 44.44 ± 14.69 years) participated. The test–retest reliability (time interval = 7 days) was assessed in 50 patients. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and smallest detectable change (SDC) were analyzed. The Persian version of functional oral intake scale (FOIS-P) was also recorded to assess construct validity. One hundred healthy subjects completed the P-EAT-10 for clinical validity. Factor analysis was performed to determine the P-EAT-10 structure. There were no missing responses and floor or ceiling effects. Internal consistency was high (Cronbach’s α 0.91). Item–total correlations exceeded acceptable standard of 0.3 for the all items (0.62–0.83). The test–retest reliability was excellent [(ICC)agreement 0.96]. The SEM and SDC were 2.61 and 7.23, respectively. Construct validity was confirmed by a significant correlation between the P-EAT-10 and FOIS-P scores (r = 0.84). Clinical validity was supported by a significant discrimination between patients and healthy subjects (t = 29.97, P < 0.001). Factor analysis indicated 2 components for the P-EAT-10. The P-EAT-10 is a valid and reliable tool and can be used in clinic and research for the assessment of oropharyngeal dysphagia in Persian-speaking patients. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
