摘要

背景與目的：本研究目的為驗證台灣版特定活動平衡信心量表(Chinese version of the Activities-specific Balance Confidence scale)應用於中風患者之再測信度。方法：本研究徵召13位居住於社區且能獨立行走之慢性中風患者，每位患者都會接受由同一位物理治療師所施測之台灣版特定活動平衡信心量表，前後共兩次。研究者使用Cronbach's α檢驗量表的內在一致性，並且利用級內相關係數(intraclass correlation coefficient, ICC)驗證再測結果之信度。結果：台灣版特定活動平衡信心量表具有很高的內在一致性(Cronbach's α=0.96)，且級內相關係數高達0.94（95%信賴區間為0.83-0.98），表示有相當良好的再測信度。結論：本研究顯示台灣版特定活動平衡信心量表有高度的內在一致性和良好的再測信度，可提供臨床治療師和研究人員一個符合台灣地區中風患者族群使用的評估工具，可應用於量測中風患者執行日常生活時自我平衡的信心程度。

Background and Purpose: The purpose of the present study was to examine the test-retest reliability of the Chinese version of the Activities-specific Balance Confidence (ABC) scale in individuals with stroke. Methods: We recruited 13 patients with chronic stroke who lived in the community and could walk independently. The Chinese version of ABC scale was administered twice by the same physical therapist for each subject. Cronbach's α was used to examine the internal consistency, and intra-class correlation coefficient (ICC) was used to assess the level of agreement between test and retest. Results: Final test items of this scale showed high internal consistency with a Cronbach's α coefficients of 0.96. The ICC was 0.94 (95% CI=0.83-0.98), indicating excellent test-retest reliability. Conclusions: The results show that the Chinese version of the ABC scale had high internal consistency and excellent test-retest reliability. It means that the Chinese version of the ABC has demonstrated acceptable measurement properties in patients with chronic stroke.
