An Evaluation of Psychometric Properties of EAT-10: A Malayalam Version

AbstractThe Eating Assessment Tool (EAT-10) is a 10-item self-administered questionnaire that assesses the severity of dysphagia symptoms, the impact of dysphagia on quality of life and treatment efficacy. EAT-10 has been adapted into several languages, including Malayalam. However, the information on the psychometric properties of EAT-10 MALAYALAM is not known. Therefore, the study aimed to evaluate the psychometric properties of the EAT-10 MALAYALAM. EAT-10 MALAYALAM questionnaire was administered to two groups of native Malayalam-speaking participants. Group 1 consisted of a total of 110 participants (76 males and 34 females) with a mean age of 52.9  ± 13.5 years diagnosed with oropharyngeal dysphagia. Group 2 consisted of 110 age and gender-matched healthy participants with normal swallow function and no history and symptoms of swallowing disorders. The test–retest reliability was assessed using Spearman’s rank correlation coefficien t between the test and the retest scores; internal consistency was assessed using Cronbach’s alpha, and Known groups validity was evaluated by comparing the EAT-10 MALAYALAM scores between the participants of both groups. The results of Spearman’s correlation coefficient showed 0.99, indicating that the EAT-10-MALAYALAM has excellent test–retest reliability. The Cronbach’s alpha was 0.94, indicating strong internal consistency. Mann–WhitneyU test showed significant differences in the scores of EAT-10-MALAYALAM between the ...
