Abstract

Although substantial information exists about factors related to who returns to work and time taken to return to work after traumatic brain injury (TBI), less is known about the stability of the work experience after the injury. One hundred sixty-five workers with complicated mild to severe traumatic brain injury were followed for 3 to 5 years postinjury. Work stability definitions included amount of time worked (amount of time worked divided by time observed postinjury) and maintenance of uninterrupted employment once a person returned to work. Amount of time worked was significantly and systematically related to brain injury severity, neuropsychological functioning at 1-month postinjury, and preinjury characteristics such as prior work stability and earnings. However, once persons returned to work, the ability to maintain uninterrupted employment was largely related to premorbid characteristics such as being older, higher income before the injury, or a preinjury job with benefits. It was also related to higher neuropsychological functioning at 1-month postinjury (reflecting the combined effects of premorbid functioning and traumatic brain injury severity), but not related to neurologic indices of severity.
