臺灣版安德森頭頸部癌症吞嚥障礙生活品質量表（MDADI-Taiwan Version）信度與效度分析

本研究目的為建立臺灣版安德森頭頸部癌症吞嚥障礙生活品質量表（MDADI-Taiwan version），並分析信度及效度。本研究流程包含三項，（1）中文化MDADI量表、（2）正式施測階段及（3）第二次施測。本研究招募100位頭頸部癌症患者為研究對象，以功能性由口進食量表（FOIS）、中文版醫院焦慮與憂鬱量表（HADS）及中文版華盛頓大學生活品質量表（UW-QOL-v4-C）為效標工具。結果顯示臺灣版安德森頭頸部癌症吞嚥障礙生活品質量表（MDADI-Taiwan version）的Cronbach’s α值為0.609～0.870，具有可接受範圍至佳的內在一致性信度；組內相關係數（ICC）為0.651～0.931，具有中等至非常良好的重測信度；內容效度為1，具佳的內容效度。臺灣版安德森頭頸部癌症吞嚥障礙生活品質量表（MDADI-Taiwan version）與功能性由口進食量表（FOIS）的r值為0.234～0.504（p < 0.05）之間、rs值介於0.277～0.530（p < 0.01）之間，具弱至中相關程度的效標關聯效度；與中文版醫院焦慮與憂鬱量表（HADS）的r值介於-0.080～-0.471之間、rs值介於-0.097～-0.468之間，具可忽略至負向中相關程度的效標關聯效度；與中文版華盛頓大學生活品質量表（UW-QOL）r值介於0.070～0.543之間、rs值介於0.064～0.546之間，具可忽略至中相關程度的效標關聯效度。本研究也討論臺灣版安德森頭頸部癌症吞嚥障礙生活品質量表（MDADI-Taiwan version）的其他研究結果發現、實務影響、研究限制及未來研究建議。

The purpose of this study was to establish the Taiwan version of the M. D. Anderson Dysphagia Inventory (MDADI-Taiwan Version) and to test its reliability and validity. Three research procedure included: (1) translation of the English wordings of the MDADI into Mandarin Chinese, (2) formal testing, and (3) re-testing. The current study recruited 100 participants who were diagnosed with head and neck cancer. Functional Oral Intake Scale (FOIS), Mandarin Chinese version of the Hospital Anxiety and Depression Scale (HADS) and University of Washington quality of life Head and Neck Questionnaire (UW-QOL-v4-C) were used in this study. The results showed that MDADI-Taiwan version has an acceptable to high internal consistent reliability (Cronbach’s α = 0.609 ~ 0.870), moderate to good test-retest reliability (ICC = 0.651 ~ 0.931), and good content validity (I-CVI = 1 and S-CVI = 1). A weak to moderate criterion-related validities between MDADI-Taiwan version and FOIS (r = 0.234 ~ 0.504, p < 0.05 and rs = 0.277 ~ 0.530, p < 0.01), and a negligible to negative moderate criterion-related validity between MDADI-Taiwan version and HADS (r = -0.080 ~ -0.471 and rs = -0.097 ~ -0.468), and a negligible to moderate criterion-related validity between MDADI-Taiwan version and UW-QOL-v4-C (r = 0.070 ~ 0.543 and rs =0.064 ~ 0.546). The other findings, implications, limitations, and future research were discussed.
