Abstract
Objective
To preliminarily validate the Visual Skills for Reading Test (VSRT) for assessing
reading performance in persons with homonymous hemianopia (HH) or quadrantanopia.
Design
Retrospective chart review.
Setting
University-based outpatient low vision rehabilitation center.
Participants
Persons (N=38) with HH or quadrantanopia who completed the VSRT.
Interventions
Validation procedures included testing for equivalence of the 3 test versions, estimation
of internal consistency reliability, and known-group comparison using VSRT results
from previous studies of adults with normal vision and central field loss.
Main Outcome Measures
Corrected reading rate, reading accuracy rate, type and number of reading errors,
and completion time were recorded and evaluated.
Results
Cronbach α for the VSRT across all participants was .80, which indicated good internal
consistency. A known-group comparison showed that persons with a visual field deficit
read significantly slower than did normally sighted adults (t580=10.13; P<.0001). Persons with quadrantanopia read significantly faster than did persons with
HH (t36=2.25; P=.03) or those with central field loss (t48=3.17; P=.0027). These findings confirmed that the VSRT correctly discriminated between groups
in terms of reading performance.
Conclusions
Preliminary validation results indicate that the VSRT demonstrates adequate evidence
of reliability and validity to evaluate reading performance in adults with HH or quadrantanopia.
