Abstract

Research has shown that traumatic brain injury (TBI) survivors frequently show deficits in executive function compared to healthy individuals. This study examines the effects of TBI on verbal fluency performance in a Latinx sample. The sample consisted of 20 persons with moderate-to-severe TBI and 23 healthy comparison participants. Independent sample T-tests were used to determine the effect of TBI on verbal fluency letter, category, and category switching performance. Persons with TBI were tested 6 months or more post-injury. All participants passed performance validity testing. We found that the healthy comparison group outperformed the TBI group on verbal fluency category and category switching, p’s<.05, ηp²=.10-.14. No significant differences between groups were found on verbal fluency letters. As expected, the TBI group performed worse than healthy comparison participants on the verbal fluency category and category switching tasks. To the authors’ knowledge, this the first study to examine the effects of TBI on verbal fluency performance using only a Latinx sample. Data suggests better verbal fluency category and category switching performance recovery in our Latinx TBI sample, but not verbal fluency letter performance. Future studies with larger sample sizes should consider variables (e.g., acculturation) if it impacts verbal fluency performance.
