To develop and investigate the reliability and validity of a Brazilian version of the 25-Item National Eye Institute Visual Function Questionnaire.
A Brazilian version of the questionnaire was developed and applied to patients with chronic eye diseases and healthy controls. Reliability was assessed by Cronbach's alpha coefficient, intraclass correlation coefficient and interrater reliability coefficient. Participants were submitted to the Medical Outcomes Study Short Form-36 Questionnaire. Validity was estimated by the correlation between the questionnaires and among the 12 subscales of the questionnaire, subscales scores and visual acuity, patients' and controls' subscales scores, and the factor analysis. Responsiveness of the questionnaire was assessed in a group of patients before and following cataract surgery.
Cronbach's alpha, intraclass correlation and interrater reliability coefficients were highly significant. Validity was well established in all tests. In patients who underwent cataract surgery, a better vision-related quality of life was observed following surgery.
The Brazilian version of the 25-Item National Eye Institute Visual Function Questionnaire has valid and reliable psychometric properties and can be applied to vision-related quality of life research.
开发并研究巴西版25项国立眼科研究所视觉功能问卷的信度和效度。
开发巴西版问卷并应用于慢性眼病患者和健康对照者。通过克朗巴哈α系数、组内相关系数和评分者间信度系数评估信度。参与者接受医学结局研究简明健康调查问卷-36。通过问卷之间、问卷的12个分量表之间、分量表得分与视力之间、患者和对照者的分量表得分之间的相关性以及因子分析来估计效度。在一组白内障手术前后的患者中评估问卷的反应度。
克朗巴哈α系数、组内相关系数和评分者间信度系数均高度显著。在所有测试中效度均得到充分确立。在接受白内障手术的患者中，术后观察到与视力相关的生活质量有所改善。
巴西版25项国立眼科研究所视觉功能问卷具有有效的和可靠的心理测量特性，可应用于与视力相关的生活质量研究。
