To 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.
Cataract 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.
The 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.
BCVA 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.
使用中文版的美国国立眼科研究所视觉功能问卷25项（CHI-NEI-VFQ-25）评估中国术前年龄相关性白内障患者的视觉相关生活质量，并分析其影响因素。
使用CHI-NEI-VFQ-25对白内障患者进行访谈，并记录他们的人口统计学信息。采用Cronbach α系数来确定CHI-NEI-VFQ-25的内部一致性。采用多特质分析来评估结构效度，包括项目收敛效度和项目区分效度。通过描述性统计分析、Kruskal-Wallis秩和检验以及多项逻辑回归对数据进行评估。
除驾驶分量表外，Cronbach α系数均高于0.8。所有项目均通过收敛效度和区分效度检验。综合得分为63.0。得分最低的五个分量表分别是总体视力（40.0）、心理健康（37.5）、角色困难（37.5）、近视力活动（50.0）和依赖（58.3）。除总体健康和眼痛分量表得分外，综合得分和分量表得分与较好眼的最佳矫正视力（BCVA）呈正相关。多项逻辑回归显示，性别、年龄和教育程度与综合得分和分量表得分显著相关。
较好眼的BCVA是与视觉相关生活质量下降相关的最重要决定因素。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。在包括性别、年龄和教育程度在内的所有人口统计学特征中，均对年龄相关性白内障患者的生活质量产生影响。
