Abstract
Objective: The Chinese version of the M. D. Anderson Symptom Inventory—Head and Neck Module (MDASI-HN-C) has been linguistically validated. However, its psychometric properties have not been established yet. The purpose of the study was to psychometrically validate the MDASI-HN-C in patients with nasopharyngeal carcinoma (NPC). Methods: 130 Chinese NPC patients who were undergoing radiotherapy (RT) participated in this cross-sectional study. The content, convergent, and construct validity of the MDASI-HN-C were examined. The reliability of the instrument was tested by examining the internal consistency and test–retest reliability. Results: Cronbach's α coefficients ranged from 0.85 to 0.91 for the three subscales of the MDASI-HN-C. The 3-day test–retest reliability was acceptable with intraclass correlation coefficients (ICC) ranged from 0.52 to 0.71. The scale content validity index (S-CVI) was satisfactory (0.97). Subscale scores of the MDASI-HN-C were negatively correlated with the total score of the Chinese version of the Functional Assessment of Cancer Therapy—Head and Neck Scale (FACT-H&N-C) as hypothesized (r = −0.484 to −0.563, all P < 0.01). Exploratory factor analysis (EFA) revealed two factors for the 13 core and another two for the nine HNC-specific items. Only one factor was generated for the six interference items. Conclusions: The MDASI-HN-C shows desirable psychometric properties for evaluating symptom burden in NPC patients, which can be used in both clinical and research contexts.
