目的研究一个适合测量我国视功能损害眼病患者的生存质量量表。方法通过指标筛选，最终选择２０个指标形成生存质量量表。应用该量表测量了５７例单纯视力损害的白内障患者和６０例有不同程度视力及视野损害的青光眼患者，并对该量表进行效度、信度和反应性的评价。结果该量表２０个指标，包括症状、视功能、身体机能、社会活动及精神心理等四个方面。（１）准则关联效度：ｒ＝０．６８６５，Ｐ＝０．０００。（２）重测信度：ｒ＝０．８９５９，Ｐ＝０．０００；克朗巴赫系数：α＝０．９３５８；方差比＝０．０５５１；分半信度：Ｒ＝０．９５５３。（３）反应度：ｔ检验＝５．９５（Ｐ＝０．０００），效应大小统计量为１．５３３。结论该量表具有满意的效度、信度和反应度。可试用于临床试验评价
Objective To study a quality of life scale suitable for measuring the impairment of visual function in our country. Methods Through the index screening, the final selection of 20 indicators to form quality of life scale. Using this scale, 57 patients with cataract with simple vision impairment and 60 patients with glaucoma with varying degrees of visual acuity and visual field damage were measured, and the validity, reliability and reactivity were evaluated. Results The scale of 20 indicators, including symptoms, visual function, physical function, social activities and mental and other four aspects. (1) The criterion correlation validity: r = 0.6865, P = 0.000. (2) retest reliability: r = 0.8959, P = 0.000; Cronbach’s coefficient: α = 0.9358; variance ratio = 0.0551; semi-reliability: R = 0.9553. (3) Reactivity: t test = 5.95 (P = 0.000), and the effect size statistic was 1.533. Conclusion The scale has satisfactory validity, reliability and responsiveness. Can be used in clinical trial evaluation
