目的采用中国眼科研究所视觉功能问卷-25（CHI-NEI-VFQ-25）对我国年龄相关性白内障患者术前视觉相关生活质量进行评估，并对其影响因素进行分析。Cronbach α系数用于确定CHI-NEI-VFQ-25的内部一致性。采用多特质分析方法，对问卷的结构效度，包括项目聚合效度和项目区分效度进行评价。资料经描述性统计分析、Kruskal-Wallis秩和检验及多项Logistic回归分析。所有项目都通过了收敛有效性测试和判别有效性测试。综合评分为63.0。最低的五个分量表得分是一般视力（40.0），心理健康（37.5），角色困难（37.5），近视活动（50.0）和依赖（58.3）。除了一般健康和眼痛的子量表评分外，综合评分和子量表评分与较好眼的最佳矫正视力（BCVA）呈正相关。多项Logistic回归分析显示，性别，年龄和教育程度显着相关的综合评分和子量表scores.ConclusionsBCVA在更好的眼睛是最重要的决定因素与视力相关的生活质量的下降。视力损害对患者生活质量的心理社会参数的影响大于其他参数。在所有的人口学特征中，包括性别、年龄和受教育程度，影响年龄相关性白内障患者的生活质量。
BackgroundTo evaluate vision-related quality of life in preoperative age-related cataract patients in China, using the Chinese version of the National Eye Institute Visual Function Questionnaire-25 (CHI-NEI-VFQ-25), together with analyses of its influencing factors.MethodsCataract patients were interviewed using the CHI-NEI-VFQ-25, and their demographic information was recorded. The Cronbach α coefficient was used to determine the internal consistency of the CHI-NEI-VFQ-25. Multi-trait analyses were used to assess construct validity, including item convergent validity and item discriminant validity. The data were evaluated by descriptive statistical analyses, by the Kruskal–Wallis rank sum test, and by multinomial logistic regression.ResultsThe Cronbach α coefficients were all above 0.8, except for the driving subscale. All items passed the convergent and discriminant validity tests. The composite score was 63.0. The lowest five subscale scores were in general vision (40.0), mental health (37.5), role difficulty (37.5), near vision activities (50.0), and dependence (58.3). Except for the subscale scores of general health and ocular pain, the composite scores and subscale scores were positively associated with the best-corrected visual acuity (BCVA) in the better eye. Multinomial logistic regression showed that sex, age, and educational attainment were significantly associated with the composite score and subscale scores.ConclusionsBCVA in the better eye was the most important determinant associated with the decrease in vision-related quality of life. Visual impairment had more impact on the psychosocial parameter than on the other parameters of the patients’ quality of life. Among all the demographic characteristics, including sex, age, and educational attainment, influenced the quality of life in age-related cataract patients.
