Traumatic Brain Injury Severity, Comorbidity, Social Support, Family Functioning, and Community Reintegration Among Veterans of the Afghanistan and Iraq Wars.

OBJECTIVE To examine the association between traumatic brain injury (TBI) severity; social, family, and community reintegration outcomes; and return to work status among post-9/11 veterans in Department of Veterans Affairs (VA) care. DESIGN Retrospective observational cohort study. SETTING Mail/online survey fielded to a national sample of veterans. PARTICIPANTS Sample of post-9/11 veterans with at least 3 years of VA care stratified according to TBI severity and comorbidities who completed and returned surveys (N=2023). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Deployment Risk and Resilience Inventory-2 family functioning and social support subscales; Military to Civilian Questionnaire; and employment status. RESULTS Bivariate analyses revealed that veterans with every classification of TBI severity reported significantly more difficulty on social, family, and community reintegration outcomes than those with no TBI. In the fully adjusted model, veterans with unclassified and moderate/severe TBI reported significantly more difficulty with community reintegration and were less likely to be employed relative to those with no TBI; those with unclassified TBI also reported significantly more difficulty with family functioning. Veterans with mild TBI also reported significantly more difficulty with community reintegration. CONCLUSIONS This study provides insight into long-term outcomes associated with TBI in post-9/11 veterans and suggests that exposure to TBI has a negative effect on social and family functioning, community reintegration, and return to work even after controlling for comorbidity, deployment experiences, and sociodemographic characteristics. Additional research is required to explicate what appears to be complex interactions among TBI severity, psychosocial well-being, combat exposures, and socioeconomic resources in this population.
