intrust structured assessment for evaluation of tbi (safe-tbi)

Conditions: Brain Injuries, Traumatic

Summary: the current study will evaluate the initial reliability and validity of a new instrument, the intrust structured assessment for evaluation of tbi (safe-tbi), in three samples of operation enduring freedom/operation iraqi freedom/operation new dawn (oef/oif/ond) veterans. the safe-tbi is a relatively brief measure developed by intrust consortium investigators and designed to be given by a trained administrator. it allows for a determination of the level of evidence for exposure to a mild traumatic brain injury (tbi) using the following categories: strong, moderate, weak, or no evidence of mild tbi. the first objective is to determine the reliability (both test-retest and inter-rater) in a sample of 100 veterans recently returned from deployment at joint base lewis-mcchord and fort bragg (cohort 1), who have screened positive for tbi on the post-deployment health assessment. the second objective is to determine the concordance between the safe-tbi and the va tbi screen in 100 oef/oif/ond veterans within the northern new england va research consortium (cohort 2). the third objective, to be carried out in a sample of 200 walter reed national military medical center (wrnmmc) and fort belvoir community hospital oef/oif/ond patients (cohort 3), is to determine the sensitivity and specificity of the safe-tbi using the intrust study "brain indices of risk for posttraumatic stress disorder after mild traumatic brain injury" initial evaluation as the "gold standard" for tbi assessment.
