These resources describe the creation and validation of the TBIMS-NSDI, a neighborhood socioeconomic deprivation index, designed to assess socioeconomic disadvantage in the context of traumatic brain injury (TBI) recovery. The index uses principal component analysis of U.S. Census data and is linked to individual-level socioeconomic data from the TBI Model Systems National Database. A residual variable is also developed to show the discrepancy between individual and neighborhood socioeconomic status. The researchers analyze how these indices relate to various TBI outcomes and demographic characteristics. The findings suggest that the TBIMS-NSDI and the residual variable provide valuable tools for understanding the influence of environmental factors on TBI recovery.
