The psychometric evaluation of the Turkish version of the Mann Assessment of Swallowing Ability in patients in the early period after stroke

Background/aim: The Mann Assessment of Swallowing Ability (MASA) is an efficient tool that allows physicians to determine the alertness, cooperation, and respiration of patients, which are important factors when assessing swallowing . This study aimed to translate the MASA into Turkish (T-MASA) and to assess its reliability and validity in patients during the early period after a stroke . Materials and methods: The scale was administered to 141 patients in the early period after a stroke. For reliability, both internal consistency (Cronbach's alpha and corrected item-to-total correlations) and interrater reliability were analyzed. The procedures were scored by two blinded independent expert observers. The validity was assessed using the convergent validity. The cut-off value of the T-MASA for dysphagia was accepted as 169 points. The correlation between the MASA and endoscopic evaluation was evaluated. Results: The T-MASA showed good internal consistency using Cronbach's alpha (0.899-0.901) and corrected item-to-total correlations. In addition, the intraclass correlation coefficient scores indicated excellent agreement. A significant moderate negative correlation was found between endoscopic evaluation and the T-MASA in terms of the presence of dysphagia (r: -0.324, r: -0.302, respectively, and both P = 0.001) Conclusion: Our results suggest that the Turkish version of the MASA is a valid and reliable instrument when determining dysphagia in patients in the early period after a stroke.
