Behavioural differences between psychiatric patients with confirmed versus non-confirmed traumatic brain injuries

Abstract

The relationship between history of Traumatic Brain Injury (TBI) and BDI-2 depression scores at admission and discharge from the hospital was assessed in acutely hospitalized psychiatric patients. The participants were assigned to three groups: (1) no reported history of TBI (n = 18), (2) reported but not confirmed TBI history (n = 13), and (3) reported and confirmed TBI history (n = 15). It was found that confirmed history of TBI was associated with elevated BDI-2 depression scores. In contrast, the non-confirmed TBI group was characterized by over-reporting of psychological distress, as measured by MMPI-2 validity indices, 100% prevalence of alcohol use history, and depression scores that were intermediate between the control and confirmed TBI groups.
