Short-term Objectives include:
1. Establishing the criterion-related validity of the Traumatic Brain Injury-4 (TBI-4) questionnaire in the Veteran homeless population using the Ohio State University TBI-Identification Method (OSU TBI-ID) (Corrigan et al., 2007) as the gold standard for establishing traumatic brain injury (TBI) diagnosis.
2. Identifying the prevalence of those that screen positive for a lifetime history of TBI among homeless Veterans.
3. Comparing psychiatric outcomes (psychiatric hospitalizations, suicide attempts and deaths, and clinical contacts) and psychosocial outcomes between those with and without a lifetime history of TBI.
