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 alpha 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.
