The test-retest reliability of the Western Aphasia Battery-Revised

The purpose of the study was to examine the test-retest reliability of the Western Aphasia Battery-Revised (WAB-R). Ten people with stroke-induced aphasia were administered the entire WAB-R twice. Correlation coefficients were .80 for 11/13 WAB-R sections/subtests. Paired t-tests revealed no significant difference between the means at Time 1 and Time 2 for any of the 13 WAB-R sections/subtests. Effect size was less than small for 11/13 WAB-R sections/subtests and small for two subtests. For 8/13 sections/subtests, one WAB-R standard error of measurement (SEM) represented less than 5% of the total number of points possible; thus, 68% of the time, persons with aphasia would be expected to score within 5% of the total number of points possible on repeated testing. For 5/13 sections/subtests, one WAB-R SEM represented more than 5% but less than 10% of the total number of points possible.
