Purpose
Communication deficits may play a critical role in maintaining employment after traumatic brain injury (TBI), but links between specific communication deficits and employment outcomes have not been determined. This study identified communication measures that distinguished stably employed versus unstably employed adults with TBI.
Methods
Participants were 31 adults with moderate-severe TBI who were employed full-time for at least 12 consecutive months before injury in skilled jobs and had attempted return to skilled jobs after injury. Sixteen had achieved stable employment (SE) post-injury, defined as full-time employment for ≥12 consecutive months; and 15 had unstable (UE) employment. Participants completed a battery of communication tests identified in a prior qualitative study of communication skills required for skilled work.
Results
Measures of spoken language comprehension, verbal reasoning, social inference, reading, and politeness in spoken discourse significantly discriminated between SE and UE groups. Two nested models were completed and compared. The first model excluded discourse data because of missing data for two UE and one SE participant. This model revealed that measures of verbal reasoning speed (β = −0.18, p = 0.05) and social inference (β = 0.19, p = 0.05) were predictive independent of the overall model. The second model included discourse data and was a better overall predictor of group membership (Likelihood ratio test, Model 1: 3.824, Model 2: 2.865).
Conclusion
Communication measures were positively associated with stable employment in skilled jobs after TBI. Clinicians should include assessment of communication for adults attempting return to work after TBI, paying specific attention to social inference and speed of verbal reasoning skills.
Traumatic brain injury (TBI) can affect developmental trajectories as well as language, attention, memory, executive functions, and other cognitive skills related to literacy. Literacy demands change through adolescence and into young adulthood, with academic literacy demands increasing and vocational literacy demands being introduced. Speech-language pathology services must evolve with the literacy needs of each client. This article discusses assessment and treatment approaches designed for adolescents with TBI and recommendations for adapting literacy interventions from the learning disabilities literature. Through proper assessment and intervention, speech-language pathologists can have a meaningful impact on the academic and vocational literacy needs of adolescents with TBI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
