OBJECTIVE. This study sought to validate the use of the Self-Report Assessment of Functional Visual Performance (SRAFVP) as a measure of the severity of activity of daily living (ADL) limitations in people with homonymous hemianopia (HH).
METHOD. Thirty adults with HH from stroke rated their level of difficulty in completing the SRAFVP.
RESULTS. The Cronbach’s αs of the SRAFVP and its three subscales (Reading, Eye–Hand Coordination, and Functional Mobility) ranged from .73 to .99. All three subscales were significantly correlated with each other and with the total SRAFVP score. Paired t tests revealed that Functional Mobility was significantly less difficult for participants to complete than Reading or Eye–Hand Coordination. Participants with complete HH reported greater difficulty in completing the Reading tasks than those with macular sparing.
CONCLUSION. The SRAFVP demonstrated acceptable reliability and validity in evaluating the severity of ADL impairment in people with HH.
Occupational therapy practitioners can use the SRAFVP to identify and characterize ADL limitations in people with HH and can use this knowledge to develop tailored interventions.
The SRAFVP can prompt occupational therapy practitioners to pay more attention to how visual limitations may affect occupational performance in clients with multiple impairments from stroke.
The SRAVFP can be used as an outcome measure to evaluate the effectiveness of occupational therapy interventions to improve performance of vision-dependent ADLs.
