 This study found that certain personality traits are associated with more severe post-concussive symptoms, PPCS, and may also be associated with reduced return to work, RTW, following mild traumatic brain injury, MTBI. Specifically, women, those with higher levels of neuroticism, openness to experience, and conscientiousness, as well as those who had extracranial injuries or high levels of depression, were more likely to experience more severe PPCS. Additionally, these same traits were associated with decreased RTW. After controlling for PPCS, however, personality traits were no longer significantly associated with RTW. This suggests that personality traits may play a role in both PPCS and RTW following MTBI, but their influence on RTW is mediated by PPCS. This article was authored by Benedict A. Madsen, Celia C. R.
