Findings demonstrated that the culturally adapted versions of questionnaires (e.g. Swallowing quality of life questionnaire [SWAL-QOL] the Dysphagia Handicap Index [DHI], the M.D. Anderson Dysphagia Inventory [MDADI], and the Eating Assessment Tool-10 [EAT-10]) for adults with dysphagia generally received strong measurement ratings for content validity and reliability as assessments of health-related quality of life. However, further work is needed to improve the cultural adaptation and validation processes. Mixed findings regarding construct validity and internal consistency. Overall, these adaptations had poor criterion validity, interpretability (i.e. the ability to assign qualitative meaning to quantitative scores), and reproducibility agreement. These measures also were notable for floor and ceiling effects, which may represent poor content validity.
