Development, Reliability, and Concurrent Validity of the American Sign Language Version of the Computerized Revised Token Test.

PURPOSE: The present study assessed the test-retest reliability of the American Sign Language (ASL) version of the Computerized Revised Token Test (CRTT-ASL) and compared the differences and similarities between ASL and English reading by Deaf and hearing users of ASL.

METHOD: Creation of the CRTT-ASL involved filming, editing, and validating CRTT instructions, sentence commands, and scoring. Deaf proficient (DP), hearing nonproficient (HNP), and hearing proficient sign language users completed the CRTT-ASL and the English self-paced, word-by-word reading CRTT (CRTT-Reading-Word Fade [CRTT-R-wf]). Both tests were administered twice, 7-14 days apart, to assess test-retest reliability.

RESULTS

Preliminary findings suggested that the CRTT-ASL was acceptably reliable for the DP group across CRTT metrics. All groups showed adequate test-retest reliability for the CRTT-R-wf. The DP group scored comparably across the two language conditions, and on average, the DP group produced significantly lower scores than the two hearing groups on the CRTT-R-wf. The hearing groups did not differ significantly from each other on the CRTT-R-wf.

CONCLUSIONS

The CRTT-ASL may be reliable for assessing Deaf ASL users, the target population for its use. These findings serve as preliminary support for clinical and research use of the novel CRTT-ASL to assess language processing in Deaf individuals who use ASL. The CRTT-ASL may be sensitive to lexical processing inefficiencies in the Deaf signing population.
