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.
