目的：为了测试在5种常见的慢性眼病中的国家眼科研究所视觉功能问卷（NEI-VFQ）的51项现场测试版本的可靠性和有效性，设计：对患有5种慢性眼病中的1种的患者进行前瞻性观察性队列研究，这些患者计划在眼科实践中进行非紧急访问或因任何原因导致视力低下，并参考无眼病的患者。六所大学的眼科实践和国家眼科研究所临床中心，Bethesda，MD患者：合格的参与者必须有以下眼部疾病之一：年龄相关性白内障，年龄相关性黄斑变性，糖尿病视网膜病变，原发性开角型青光眼，巨细胞病毒视网膜炎或任何原因的低视力。7个研究中心中的每个研究中心还在参考样本中招募了人员。参考样本参与者没有基础眼部疾病的证据，但计划进行筛查性眼部检查或屈光不正矫正。所有符合条件的受试者必须年满21岁，会说英语，认知能力强，能够提供知情同意并参与健康状况访谈。为了提供评估51项NEI-VFQ的信度和效度所需的数据，所有受试者完成了包括51项NEI-VFQ、医学结局研究36项简表健康调查、内部一致性和重测重复性的估计表明，51项NEI-VFQ是可靠的。与其他规模和临床变量的关联测试支持结构效度的surveillance.Conclusions：在这项横断面研究中，51项NEI-VFQ似乎是可靠的和有效的，应该是一个有用的工具，组水平的比较，有针对性的，健康相关的生活质量在临床研究。此外，NEI-VFQ的心理测量特性不受潜在眼病的类型或严重程度的影响，这表明当在多种眼病中使用时，该测量将提供可重复和有效的数据。
Objective: To test the reliability and validity of the 51-item Field Test Version of the National Eye Institute Visual Function Questionnaire (NEI-VFQ) across 5 common chronic eye conditions.Design: Prospective observational cohort study of persons with 1 of 5 chronic eye diseases who were scheduled for nonurgent visits in ophthalmology practices or had low vision from any cause, and a reference sample of persons without eye disease.Setting: Six university-based ophthalmology practices and the National Eye Institute Clinical Center, Bethesda, Md.Patients: Eligible participants had to have 1 of the following eye conditions: age-related cataracts, age-related macular degeneration, diabetic retinopathy, primary open-angle glaucoma, cytomegalovirus retinitis, or low vision from any cause. Each of the 7 sites also enrolled persons in a reference sample. Reference sample participants had no evidence of underlying eye disease but were scheduled for either screening eye examinations or correction of refractive error. All eligible persons had to be aged 21 years or older, English speaking, and cognitively able to give informed consent and participate in a health status interview.Measurements and Main Results: To provide the data needed to assess the reliability and validity of the 51-item NEI-VFQ, all subjects completed an interview that consisted of the 51-item NEI-VFQ, the Medical Outcomes Study 36-Item Short-Form Health Survey, and at least 1 measure of vision-targeted functional status, Estimates of internal consistency and test-retest reproducibility indicate that the 51-item NEI-VFQ is reliable. Tests of association with other scales and clinical variables support the construct validity of the survey.Conclusions: In this cross-sectional study, the 51-item NEI-VFQ seems to be reliable and valid and should be a useful tool for group-level comparisons of vision-targeted, health-related quality of life in clinical research. Additionally, the psychometric properties of the NEI-VFQ were not influenced by the type or severity of the underlying eye disease, suggesting that the measure will provide reproducible and valid data when used across multiple eye conditions.
