摘　　要：目的探讨制定一个可量化测定视力下降人群视功能相关生活质量的量表,评价其信度和效度.方法翻译英文版'低视力者生活质量量表'(LVQOL)为中文版CLVQOL.采用单纯随机抽样,设置原始组和对照组.原始组间隔2周再次复查,成为重测组.分析量表的内在一致性、重测信度、内容效度、结构效度及判别效度,计算不同性别、年龄、学历及视力与CLVQOL量表得分的相关性. 结果经过系统的翻译、回译及文化调适步骤后所得的CLVQOL量表无论是在临床患者,还是在社区居民中克朗巴赫α系数和分半信度都在0.75～0.97之间,重测信度的组内相关系数在0.69～0.95之间.各条目集合效度的相关系数均在0.4以上,而条目判别效度绝大多数在0.4以下.因子分析共提出4个公共因子.原始组的CLVQOL各维和总体得分比对照组明显低.CLVQOL得分在不同性别、年龄和学历之间无差异,与视力的相关系数高.结论 CLVQOL符合中国的文化特点;其信度、效度均高,适用于临床和社区等各种人群,是能敏感地反映视力下降人群与视功能相关生活质量状况的量表.Objective To develop and evaluate a Chinese language vision health related quality of life (VRQoL) questionnaire Methods The low vision quality of life questionnaire (LVQOL) was translated and adapted into the Chinese version low vision quality of life questionnaire (CLVQOL) The systematic protocols were set as 3 forward translations, 2 committee reviews and 1 back ward translation The CLVQOL was performed in 100 randomly selected people with low vision (primary group) and 100 people with normal vision (control group) Ninety four participants from the primary group completed the CLVQOL and repeated 2 weeks later (test retest group) The results were compared with patient demographics and the internal consistency reliability, test retest reliability, item internal consistency, item discrimination validity, construct validity and discrimination validity of the CLVQOL were calculated Results The review committee agreed that the CLVQOL replicated the meaning of the LVQOL and was sensitive to cultural adaptations The Cronbach α coefficient and the split half coefficient for the four scales and total CLVQOL scales were 0 75 to 0 97 The test retest reliability as estimated by intraclass correlation coefficient was 0 69 to 0 95 Item internal consistency was >0 4 and item discrimination validity was generally <0 40 The varimax rotation factor analysis of the CLVQOL identified four principal factors All of the scores of four subscales and the total score of CLVQOL of the primary group were lower than those of the control group, both in patients and local residents CLVQOL scores were highly correlated with visual acuity Conclusions The CLVQOL is a culturally specific VRQOL measure instrument CLVQOL can satisfy conventional psychometric criteria, can discriminate visually healthy populations from low vision patients and is valuable in the clinical practice and in the screening of the community populations
