Preliminary validation of a vision-dependent activities of daily living instrument on adults with homonymous hemianopia.

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). Thirty adults with HH from stroke rated their level of difficulty in completing the SRAFVP. 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. The SRAFVP demonstrated acceptable reliability and validity in evaluating the severity of ADL impairment in people with HH. Copyright © 2012 by the American Occupational Therapy Association, Inc.
