失智症態度量表中文版之發展與信效度驗證

目標：本研究旨在發展失智症態度的中文版量表（Dementia Attitude Scale -Chinese Version, DAS-C），以測量一般大眾對失智症的態度並驗證其心理測量特性。方法：參考Beaton等人的跨文化翻譯指引，翻譯成中文版量表，原始量表有20題，採用7分李克特計分，得分越高表示態度越正向。量表收案對象包括參與失智友善課程的大學生和兩家金融機構的臨櫃人員，並於課前進行問卷調查。內容效度由相關領域專家進行評估，並採取項目分析評估量表題目，使用主軸因素法進行探索性因素分析，建立量表整體的效度，信度測試使用Cronbach's alpha值。結果：5位專家對翻譯後的DAS-C量表內容進行評估，S-CVI值為0.94-1.00達到標準。共236人納入樣本，經項目分析刪減合計3項或以上指標未達標準的題目後共17題；透過主軸因素法萃取三個因素，分別為認知、情感和行為。DAS-C整體信度為0.83。結論：DAS-C具有良好的信效度，可以有效測量一般大眾對失智症的態度，未來研究建議擴大收案對象，以進一步驗證此量表在台的適用性。

Objectives: This study developed the Chinese version of the Dementia Attitude Scale (DAS), which measures attitudes about dementia, and its psychometric properties were tested on individuals from the general population. Methods: This study developed the DAS-Chinese version (DAS-C) following Beaton's cross-cultural translation guidelines. The original DAS has 20 items rated on a 7-point Likert scale, with higher scores indicating more positive attitudes. We recruited college students and frontline staff from two banks in Taiwan, who completed the questionnaire before attending dementia-friendly lectures. The content validity of DAS-C was established by an expert panel by using the scale-level content validity index (S-CVI), and item analysis was performed for each item. Exploratory factor analysis was performed through principal axis analysis (PAF) to establish the construct validity of the scale, and reliability was measured using Cronbach's α. Results: The content of the DAS-C was verified by five experts, and the S-CVI value of 0.94-1.00 was satisfactory. A total of 236 completed questionnaires were included in the analysis. After removal of the items that failed to meet three or more criteria based on item analysis results, the DAS-C contained 17 items. PAF revealed a three-factor structure: cognitive, affective, and behavioral factors. The revised DAS showed acceptable internal consistency overall (Cronbach's α = 0.83). Conclusions: The 17-item DAS-C has good validity and reliability and can effectively measure the general public's attitudes toward individuals with dementia. Future studies with larger sample sizes and individuals with different characteristics are warranted to further validate the use of the DAS-C in Taiwan.
