The use of different measures to assess similar study variables and/or assess outcomes limits important advances in psychological health (PH) and TBI research. Without a set of common data elements (CDE) comparison of findings across studies is challenging. The federal agencies involved in PH and TBI research, the National Institute of Neurological Disorders and Stroke, Department of Veterans Affairs, National Institute on Disability and Rehabilitation Research, Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury, and Defense and Veterans Brain Injury Center, therefore cosponsored a scientific initiative to develop CDEs for PH and TBI research. Scientific experts were invited to participate in 1 of 8 working groups to develop recommendations for specific topic driven CDEs.
Position Statement: Definition of Traumatic Brain Injury

A clear, concise definition of traumatic brain injury (TBI) is fundamental for reporting, comparison, and interpretation of studies on TBI. TBI is defined as an alteration in brain function, or other evidence of brain pathology, caused by an external force. This article discusses new criteria for considering or establishing a diagnosis of TBI, with a particular focus on the problems of how a diagnosis of TBI can be made when patients present late after injury and how mild TBI may be differentiated from non-TBI causes with similar symptoms.
