中文版吞咽生存質量量表（SWAL-QOL）在腦卒中患者中信度和效度研究
The reliability and validity of the Chinese version of swallowing quality of life questionnaire (SWAL-QOL) in stroke patients with dysphagia
摘要
目的：探討中文版吞咽生存質量量表SWAL-QOL用於評估澳門腦卒中吞咽障礙患者生存質量的各種信度及效度。方法：選取符合入選標準的腦卒中吞咽障礙患者82例為受試者，用中文版SWAL-QOL評估。對其測量者間信度、重測信度、同質性信度、內容效度和結構效度進行檢測。結果：中文版SWAL-QOL的測量者間信度相關係數為0.921～0.987（P<0.01）；重測信度相關係數為0.908～0.975（P<0.01）；同質性信度，即量表內部一致性指標Cronbachα係數在0.769～0.973（P<0.01）；每一個條目與其所在領域的相關係數為0.754～0.978（P<0.01），且每一個條目與其所在維度的相關係數均高於與其他維度的相關係數；在10個維度總分的因子分析中提取出2個公因子（吞咽相關生存質量領域和普通生存質量領域），累計貢獻率為57.438%。結論：中文版吞咽生存質量量表SWAL-QOL具有良好的信度和效度，可作為一種有效的測量工具對腦卒中吞咽障礙患者的生存質量進行評估。

Objective: To evaluate various reliabilities and validities of Chinese version of swallowing quality of life questionnaire (SWAL-QOL) in Macau stroke patients with dysphagia. Methods: After translation and cultural adaptation, SWAL-QOL was used to evaluate the QOL of 82 stroke patients with dysphagia. The inter-rater reliability, test-retest reliability, internal consistency reliability, the content validity and construct validity will be examined in this study. Results: The intergroup correlation coefficient (ICCS) of SWAL-QOL and its domains were in the range of 0.921 - 0.987 (P<0.01). The coefficient test=retest coefficients of SWAL-QOL and its domains were 0.908 - 0.975 (P<0.01). The Cronbach coefficients range from 0.769 to 0.973 (P<0.01). Significant correlation was shown between each entry of WSAL-QOL and its domain, the correlation coefficients were 0.754 - 0.978 (P<0.01). Factor analysis was used for the ten scales of the SWAL-QOL and found two common factors, namely dysphagia specific quality of life factor and generic factor. These two factors' cumulative contribution was 57.44%. Conclusion: The Chinese version of SWAL-QOL is reliable and valid. It can be used as an effective measuring tool to evaluate the quality of life in stroke patients with dysphagia.
