Validation of the action naming test with videos (T-DAV) in individuals with post-stroke aphasia

Verb anomia is a key symptom in individuals with post-stroke aphasia, yet its assessment tools remain limited. The Action Naming Test With Videos (T-DAV) had not yet been validated for this population. This study aims to validate the T-DAV in individuals with post-stroke aphasia by exploring the effects of lexical frequency and phonemic cues on naming performance. Discriminant validity was examined by comparing the performance of 18 individuals with post-stroke aphasia with that of healthy participants. The effect of lexical frequency was also analyzed. The T-DAV accurately differentiated the performance of patients and healthy participants, showing good discriminant validity. A frequency effect was observed, and phonemic cues improved performance in individuals with post-stroke aphasia. The T-DAV addresses a need in the French-speaking assessment of verb anomia in post-stroke aphasia, thereby facilitating more targeted therapeutic interventions.
