Abstract

OBJECTIVE

Our objective was to validate the construct of the Revised Self-Report Assessment of Functional Visual Performance (R-SRAFVP) for older adults with low vision resulting from age-related eye disease.

METHOD

The 50-item draft of the R-SRAFVP was administered to 87 older adults with low vision. Construct validation included principal-components analysis and the known-groups method.

RESULTS

Principal-components analysis revealed nine components (comprising 33 items): Personal Care, Oral Care, Meal/Laundry Preparation, Financial Management, Telephone Usage, Personal Preference Activities, Reading, Writing, and Functional Mobility. Cronbach's α ranged from .72 to .84 for individual components and was .92 overall. Known-groups comparisons showed that participants with moderate to profound acuity loss or contrast sensitivity deficits reported significantly greater difficulty completing tasks on the R-SRAFVP than those with milder acuity loss or normal contrast sensitivity.

CONCLUSION

The 33-item R-SRAFVP demonstrates adequate evidence of reliability and validity to evaluate the ability of older adults with low vision to complete vision-dependent activities of daily living.

摘要

目的

我们的目的是验证修订后的功能视觉表现自我报告评估量表（R-SRAFVP）对于因年龄相关性眼病导致视力低下的老年人的结构效度。

方法

将R-SRAFVP的50项初稿施用于87名视力低下的老年人。结构效度验证包括主成分分析和已知群体法。

结果

主成分分析揭示了九个成分（包含33个项目）：个人护理、口腔护理、膳食/洗衣准备、财务管理、电话使用、个人偏好活动、阅读、写作和功能移动性。各个成分的Cronbach's α系数在0.72至0.84之间，总体为0.92。已知群体比较表明，与视力轻度下降或对比敏感度正常的参与者相比，中度至重度视力丧失或对比敏感度缺陷的参与者在R-SRAFVP上完成任务时报告的困难程度明显更高。
