Abstract

The purpose of this study was to assess the test-retest reliability of the Computerized Revised Token Test (CRTT) and three CRTT-R reading versions in normal elderly individuals (NEI) and in persons with aphasia (PWA). Results revealed high correlation coefficients between test and retest performance for all CRTT versions in the PWA and moderate to high correlations in the NEI. There were no significant differences among test-retest conditions for overall and subtest scores except for the reading word-fade condition (both groups) and auditory condition for the PWA. Overall, high test-retest reliability of the CRTT and the three CRTT-R versions was demonstrated.
