Summary
Racial and ethnic disparities in arrest probability persist 10 years after traumatic brain injury (TBI). These differences remain even after accounting for injury and sociodemographic factors, highlighting the need for targeted interventions.
Area of Science:
- Neuroscience and Public Health
- Traumatic Brain Injury (TBI) Research
- Health Disparities
Background:
- Existing research indicates racial/ethnic variations in traumatic brain injury (TBI) risk, etiology, care, and recovery.
- Understanding long-term outcomes, such as legal involvement, is crucial for comprehensive TBI care.
- Previous studies have not fully explored racial/ethnic differences in arrest probability trajectories post-TBI.
Purpose of the Study:
- To examine racial/ethnic disparities in arrest probability over the first decade following moderate-to-severe traumatic brain injury (TBI).
- To determine if injury characteristics and sociodemographic factors explain these observed racial/ethnic differences in arrest probability.
- To identify specific groups at higher risk for post-TBI legal involvement.
Main Methods:
- Analysis of a large cohort (13,195 participants) from the TBI Model Systems National Database with moderate-to-severe TBI.
- Inclusion of arrest data from multiple follow-up points (Years 1, 2, 5, and 10 post-injury).
- Application of hierarchical linear models to assess racial/ethnic differences in arrest probability trajectories, controlling for covariates.
Main Results:
- White individuals with TBI exhibited lower arrest probability trajectories compared to Black and Native American individuals.
- Asian individuals with TBI had significantly lower arrest probability trajectories than White, Black, Latinx, and Native American individuals.
- Racial/ethnic disparities in arrest probability often persisted even after adjusting for sociodemographic and injury-related factors.
Conclusions:
- Significant racial/ethnic disparities in long-term arrest probability exist following TBI.
- Rehabilitation clinicians must proactively assess for risk factors like age, sex, education, unemployment, prior arrests, and substance abuse.
- Targeted interventions are needed, especially for Black, Latinx, and Native American populations, to reduce post-TBI arrest risk and enhance rehabilitation outcomes.
