Psychometric Properties of the Chinese Version of the M.D. Anderson Dysphagia Inventory for Head and Neck Cancer Patients

Background: Dysphagia is a common side effect of anticancer treatments in patients with head and neck cancer (HNC) and can worsen patients’ quality of life. A well-established measure is essential to evaluate dysphagia in HNC patients. Objectives: The aim of this study is to determine the psychometric properties of the Chinese version of the M.D. Anderson Dysphagia Inventory (MDADI-C) for HNC patients. Methods: A total of 220 subjects were included in the study. Reliability was examined by internal consistency (Cronbach’s α) and test-retest reliability (intraclass correlation coefficient). Validity was evaluated with Spearman correlations (r). Results: The Cronbach’s α and intraclass correlation coefficient of the MDADI-C were .923 and 0.942, respectively. The criterion validity of the MDADI-C was 0.777. The Spearman correlation coefficients of the MDADI-C with the European Organization for Research Into the Treatment of Cancer Quality of Life Questionnaire for Head and Neck Cancer (r = −0.851), Hospital Anxiety and Depression Scale (r = −0.424), radiotherapy dose (r = −0.553), and treatment regimens (r = −0.407) demonstrated good construct validity (all P
