Postconcussion syndrome (PCS), the protracted recovery profile following a TBI is not well understood. Previous investigations suggest premorbid and post-injury factors may play a pathogenic role, though few investigations have examined interaction effects. The purpose of this study was the examination of factors contributing to the severity of PCS. Eighty-seven participants (recruited online) that endorsed history of TBI, completed the Insomnia Severity Index, Epworth Sleepiness Scale, Big Five Inventory 10, and the Neurobehavioral Symptom Inventory. A moderating effect of high conscientiousness on the relationship between measures of daytime sleepiness and PCS was observed (ΔR2 = .054, F (1, 83) = 6.51, p < .05). Both high and low neuroticism moderated the relationship between insomnia and PCS severity (ΔR2 = .035, F (1, 83) = 5.01, p < .05). While these results were unexpected they offer a route to a greater degree of personalized rehabilitation services following TBI.
