The Turkish M.D.
Anderson Dysphagia Inventory works well for neurological patients. It takes 5–10 minutes, has no missing data issues, and matches the longer SWAL-QOL. Use it to quickly assess swallowing-related quality of life without cultural bias.
Key findings
01The Turkish version of the MDADI showed excellent internal consistency and test-retest reliability, with Cronbach's alpha ranging from 0.89 to 0.96 and ICCs from 0.81 to 0.95.
02The questionnaire is feasible for clinical use, with patients completing it in 5–10 minutes and no missing items reported.
03Convergent validity was supported by significant correlations with the Turkish SWAL-QOL, particularly in food selection, mental health, and social functioning domains.

What it does not show
The patient group was heterogeneous, mixing stroke, MS, Parkinson's, and other conditions, so the tool's performance may vary by specific disease. Factor analysis was not conducted, so the structural validity of the subscales is not confirmed. High Cronbach's alpha values (above 0.90) might suggest some item redundancy, though no specific redundant items were identified in this analysis.

The easy way to misread this
Do not assume this tool is validated for head and neck cancer patients. This study only tested it in people with neurological diseases like stroke and MS.
