Evidence indicates that substance use and mental health treatment is often associated with reduced criminal activity. The present systematic review examined this association among military veterans, and aimed to provide a comprehensive summary of needed research to further contribute to reduced criminal activity among veterans. This systematic review was derived from a scoping review that mapped existing research on justice-involved veterans health. For the current systematic review, a subset of 20 publications was selected that addressed the question of whether criminal activity declines among veterans treated for substance use and mental health disorders. Generally, veterans improved on criminal outcomes from pre- to post-treatment for opioid use, other substance use, or mental health conditions, and more sustained treatment was associated with better outcomes. This occurred despite high rates of criminal involvement among veterans prior to entering treatment. Needed are substance use and mental health treatment studies that include women justice-involved veterans, follow criminally-active veterans for longer periods of time, and use validated and reliable measures of criminal activity with fully transparent statistical procedures. Future randomized trials should evaluate new treatments against evidence-based treatments (versus no-treatment control conditions). Subsequent studies should examine how to link veterans to effective treatments, facilitate sustained treatment engagement, and ensure the availability of effective treatments, and examine mechanisms (mediators and moderators) that explain the association of treatment with reduced criminal activity among veterans. Best practices are needed for reducing criminal activity among the minority of justice-involved veterans who do not have diagnosed substance use and/or mental health disorders.

Veterans often need civil legal services, yet little is known about veterans use and consequences of these services. This study examined veterans seeking legal services at VA-housed legal clinics. Baseline data from 61 clients of two VA-housed legal clinics were used to identify clients legal needs and psychosocial characteristics. Data collected from 49 (80%) of the same clients two months later were used to address clients improvement and satisfaction after receiving legal services. At baseline, clients reported a mean of 6.0 (SD = 4.2) legal needs, with the most common being help obtaining VA benefits (87%). Clients represented a vulnerable population in that most had an extensive criminal history (e.g., had been arrested, charged, and incarcerated) and multiple health care needs (had a chronic medical condition, had recently received treatment in an emergency department, and had received psychological treatment due to significant psychological symptoms). At follow-up, clients reported a mean of 4.4 (SD = 3.8) legal needs. Tests to identify changes between baseline and follow-up on legal needs, housing arrangement, psychological symptoms, and substance use yielded few significant results. Most participants did not receive additional help with their legal matters after the baseline appointment. At follow-up, clients reported that few of their legal needs were met but also that they were mostly satisfied with the legal services they received. Findings suggest that because clients may need more intensive legal intervention of longer duration to resolve their legal needs and achieve better housing and health status, VA-housed legal clinics require greater resources and expansion.

Legal clinics housed by the Department of Veterans Affairs (VA) help veterans eliminate service access barriers. In this survey of 95 VA-housed legal clinics (70% of clinics), clients legal problems were mainly estate planning, family, obtaining VA benefits, and housing (14-17% of clients). Most clinics rarely interacted with VA health care providers, did not have access to clients VA health care records, and did not track clients VA health care access (58-81% of clinics); 32% did not have dedicated and adequate space. Most clinic staff members were unpaid. Survey findings-that most VA-housed legal clinics do not interact with VA health care or directly address clients mental health and substance use needs, and lack funds to serve fully all veterans seeking services-suggest that VA and community agencies should enact policies that expand and fund veterans legal services and health system interactions to address health inequities and improve health outcomes.

Background

In the criminal justice system, special populations, such as older adults or patients with infectious diseases, have been identified as particularly vulnerable to poor health outcomes. Military veterans involved in the criminal justice system are also a vulnerable population warranting attention because of their unique healthcare needs. This review aims to provide an overview of existing literature on justice-involved veterans' health and healthcare to identify research gaps and inform policy and practice.

Methods

A systematic search was conducted to identify research articles related to justice-involved veterans' health and healthcare that were published prior to December 2017. Study characteristics including healthcare category, study design, sample size, and funding source were extracted and summarized with the aim of providing an overview of extant literature.

Results

The search strategy initially identified 1830 unique abstracts with 1387 abstracts then excluded. Full-text review of 443 articles was conducted with 252 excluded. There were 191 articles included, most related to veterans' mental health (130/191, 68%) or homelessness (24/191, 13%). Most studies used an observational design (173/191, 91%).

Conclusions

Knowledge gaps identified from the review provide guidance on future areas of research. Studies on different sociodemographic groups, medical conditions, and the management of multiple conditions and psychosocial challenges are needed. Developing and testing interventions, especially randomized trials, to address justice-involved veterans care needs will help to improve their health and healthcare. Finally, an integrated conceptual framework that draws from diverse disciplines, such as criminology, health services, psychology, and implementation science is needed to inform research, policy and practice focused on justice-involved veterans.
