Purpose: This study reports the psychometric development of the Cantonese versions of the English Computerized Revised Token Test (CRTT) for persons with aphasia (PWAs) and healthy controls (HCs). Method: The English CRTT was translated into standard Chinese for the Reading--Word Fade version (CRTT-R-[subscript WF]-Cantonese) and into formal Cantonese for the Listening version (CRTT-L-Cantonese). Thirty-two adult native Cantonese PWAs and 42 HCs were tested on both versions of CRTT-Cantonese tests and on the Cantonese Aphasia Battery to measure the construct and concurrent validity of CRTT-Cantonese tests. The HCs were retested on both versions of the CRTT-Cantonese tests, whereas the PWAs were randomly assigned for retesting on either version to measure the test--retest reliability. Results: A two-way, Group × Modality, repeated-measures analysis of variance revealed significantly lower scores for the PWA group than the HC group for both reading and listening. Other comparisons were not significant. A high and significant correlation was found between the CRTT-R-[subscript WF]-Cantonese and the CRTT-L-Cantonese in PWAs, and 87% of the PWAs showed nonsignificantly different performance across the CRTT-Cantonese tests based on the Revised Standardized Difference Test. The CRTT-R-[subscript WF]-Cantonese provided better aphasia diagnostic sensitivity (100%) and specificity (83.30%) values than the CRTT-L-Cantonese. Pearson correlation coefficients revealed significant moderate correlations between the Cantonese Aphasia Battery scores and the CRTT-Cantonese tests in PWAs, supporting adequate concurrent validity. Intraclass correlation coefficient showed high test-retest reliability (between 0.82 and 0.96, p < 0.001) for both CRTT-Cantonese tests for both groups. Conclusions: Results support that the validly translated CRTT-R-[subscript WF]-Cantonese and CRTT-L-Cantonese tests significantly differentiate the reading and listening comprehension of PWAs from HCs and provides acceptable concurrent validity and high test-retest reliability for both tests. Furthermore, favorable PWA versus HC sensitivity and specificity cutoff scores are presented for both CRTT-Cantonese listening and reading tests.
