Abstract

The present study investigated the relationship between psychosocial and neurocognitive vulnerabilities that contribute to a history of suicide attempt among persons in the criminal legal system who have a history of traumatic brain injury (TBI). The archival dataset used for this study consisted of records from 710 justice-involved participants. Results suggest that persons with a history of mental illness or who were a victim of violence as a child or adult were more likely to report a history of one or more suicide attempts. Additionally, results suggest that deficits in reaction time, processing speed, and spatial working memory were also predictive of a suicide attempt history. Persons in the criminal legal system are at the highest risk of suicide and persons with a history of brain injury are also at an increased high risk for suicide. To reduce the risk of suicide in this vulnerable population, this study affirms that treatment for people with mental illness or trauma history is critical, especially for the vulnerable persons with brain injury in the criminal legal system.
