Our aim was to adapt and examine the cultural validity and reliability of a swallowing\u2010related quality of life measure, the MD Anderson Dysphagia Inventory (MDADI), in English and Chinese, with head and neck cancer patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We adapted the MDADI to Chinese through formal forward\u2010backward translation. Sixty\u2010six head and neck cancer survivors completed the MDADI, Swallowing Quality of Life (SWAL\u2010QOL) questionnaire and Hospital Anxiety and Depression Scale (HADS) in English or Chinese. Swallowing status was scored on the Functional Oral Intake Scale (FOIS). Seventy\u2010four percent (<jats:italic>n<\/jats:italic> = 49) of participants completed a repeat administration of the MDADI for test\u2013retest reliability analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The MDADI showed high internal consistency reliability (Cronbach's <jats:italic>\u03b1<\/jats:italic> , 0.82\u00a0\u2264\u00a0<jats:italic>\u03b1\u00a0<\/jats:italic>\u2264\u00a00.94), and test\u2013retest reliability in both English (intraclass correlation coefficient, ICC = 0.81) and Chinese (ICC = 0.72). Criterion validity was established through moderate to strong correlations with relevant SWAL\u2010QOL domains. Convergent validity was determined by significant correlations to the HADS and FOIS. Divergent validity was determined by nonsignificant association to the SWAL\u2010QOL Sleep domain.
