摘要

目的：研究中文版视觉训练视光师学会生存质量量表（COVD-QOL）的信度和效度。方法：横断面调查研究。应用Brislin翻译模型对美国视觉训练视光师学会生存质量量表（19个条目）进行汉化，即先将英文版量表翻译成中文版，再回译成英文版，专家组对个别条目进行调适，形成最终中文版。 2018年1月抽取118名20～23岁的厦门医学院大学生受试者进行中文版量表的调查测试，3周后其中的80名参加了重复测试，采用项目分析、克朗巴赫系数和重测信度Pearson相关分析、内容效度和结构效度进行数据分析。结果：项目分析显示，各个条目与量表总分均相关，相关系数在0.333～0.684 之间（P<0.01）；量表信度检测发现Cronbach's α系数为0.791；重测信度采用Pearson相关分析，重测信度良好（r=0.750，P=0.002）；内容效度指数为0.985，探索性因子分析提取6个公因子，共解释了 62.3%的总方差，但6个公因子难以做专业解释，量表的结构效度欠佳。结论：中文版COVD-QOL具有良好的信度、重测信度和内容效度，结构效度有待改进，可以应用于评估大学生双眼视异常患者的生存质量。

Abstract：

Objective: To examine the test-retest reliability and validity of the College of Optometrists in Vision Development Quality of Life questionnaire (COVD-QOL) that had been translated and culturally adapted to the Mandarin Chinese language. Methods: In this cross-section study, the final Chinese version of COVD-QOL was established after translation, back-translation and cognitive interviews based on the Brislin translation model. A sample of 20-23 year-old subjects (118 participants) from Xiamen Medical College completed the Chinese version of COVD-QOL, only 80 subjects were retested after three weeks. All data were analyzed using item analysisi, Cronbach's α coeffcient, retest reliability and so on. Results: The correlation coefficient between each item score and total score ranged from 0.333 to 0.684 (P<0.01). The coefficient of internal consistency (Cronbach's α) was 0.791, the Chinese version of COVD-QOL had good retest reliability with a Pearson correlation coefficient of 0.750 (P=0.002). The content validity index was 0.985. The construct validity was not good, because six factors were extracted by exploratory factor analysis, which could explain 62.3% of the total variance, but the results cannot be analyzed by professional interpretation. Conclusions: The Chinese version of COVD-QOL demonstrates good test-retest reliability and content validity. This questionnaire is an appropriate tool to assess the changes in visual symptoms for these native Chinese language speakers.
