Validity and Reliability of an Arabic Version of MD Anderson Dysphagia Inventory (MDADI)

Abstract

Dysphagia is a common adverse event among head and neck (H&N) cancer patients. We aimed, for the first time, to validate the Arabic version of the MD Anderson Dysphagia Inventory (MDADI) among 82 Saudi Arabian patients with H&N cancer. We followed established validation guidelines and translated the 20-item MDADI using the forward-backward method. Our results revealed 100% feasibility. Test-retest reliability demonstrated acceptable interclass correlation coefficients (ICC) for the subscale domains (emotional = 0.973, physical = 0.971, and functional = 0.956) and composite score (ICC = 0.984). The Cronbach's alpha coefficients for the emotional, functional, and physical subscales were 0.937, 0.825, and 0.945, respectively (composite score = 0.975). We confirmed concurrent validity by demonstrating significant correlations between the domains of the Arabic MDADI and European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Head and Neck Module (QLQ-H&N35). Our study validated the Arabic version of the MDADI among H&N cancer patients from Saudi Arabia.
