Justice Reinvestment in Vermont: Improving Supervision to Reduce Recidivism

By Cassondra Warney, Ellen Whelan-Wuest, Madeleine Dardeau

This policy framework outlines policy options developed as part of a Justice Reinvestment Initiative effort in Vermont in 2019 in collaboration with Vermont’s Justice Reinvestment II Working Group. Many of the policies were reflected in legislation signed into law in 2020. The aim of these policies was to improve post-release supervision, achieve a more equitable criminal justice system, increase data collection and analysis, and, ultimately, reduce recidivism.

Illinois work release centers: Perspectives of prison administration and program staff.

By Ryan Maranville, Emilee Gree, and Jessica Reichert

Illinois’ prison work release centers, called Adult Transition Centers (ATCs), connect incarcerated people to vocational opportunities to support successful community reentry. As part of a larger process and outcome evaluation of Illinois ATCs, we conducted 16 interviews with Illinois Department of Corrections administrators and ATC program staff to understand their perceptions about ATC operations and purpose as well as their perspectives on ATC effectiveness, strengths, and weaknesses. Participants noted that ATCs offer individualized behavioral health treatment, build educational and vocational skills, and provide promising employment prospects upon release. Interviewees believed they fostered positive relationships with work release participants, contributing to their success. However, interviewees believed the effectiveness of work release programs may be reduced when participation is relatively short and community-based social support services are insufficient. Relevant research and some considerations of our findings are discussed.

Exploring the factors influencing prison incentive scheme status among adult males: A prospective longitudinal study

By Michelle Butler,, Catherine B. McName, Dominic Kelly

Despite its impact on imprisonment, no quantitative study has examined the factors related to people's status on prison incentive schemes. This study addresses this gap by using administrative data to explore the factors related to the status of 405 men on a prison incentive scheme. Results revealed that those who had a prior history of passing prison drug tests at time 1, and spent more time imprisoned during the follow-up period, were more likely to be on the highest level of the scheme one year later at time 2. In contrast, those who had a history of past involvement in misconduct, referrals for serious self-harm/attempted suicide in prison, not taken a prison drug test, property offences, and greater periods of custody at time  were more likely to be on the lower levels of the scheme at time . The potential implications for theory, policy, and practice are discussed.

Risk Factors for Interpersonal Violence in Prison: Evidence From Longitudinal Administrative Prison Data in Northern Ireland

By Michelle Butler https://orcid.org/0000-0002-6983-6215michelle.butler@qub.ac.uk, Catherine B. McNamee, and  Dominic Kelly

The present study uses a prospective longitudinal research design to examine whether previously identified risk factors for prison interpersonal violence can predict violent prison misconduct in Northern Ireland (NI). Administrative data drawn from the records of 429 adult males imprisoned on November 22, 2017 were used to predict involvement in violent prison misconduct during a 1-year follow-up period. The results revealed that only a small number of previously identified risk factors were found to be significant in the NI context. Nationality, neighborhood deprivation, history of addiction, submission of prison complaints, past involvement in prison misconduct, and number of incarcerations emerged as significant, while religion, head injury/epilepsy, property offences, and prison visits were significant at the marginal level. Given the variation in risk factors identified as significant in the NI context compared to previous research, it is argued that cultural context matters when attempting to generalize the risk factors for prison interpersonal violence from one jurisdiction to another. These results offer some support for the importation theory, although it should be noted that the inclusion of prison environmental factors was limited due to the nature of the data. It is argued that specialist services and supports should be provided to address the factors contributing to interpersonal prison violence, including interventions to improve feelings of fairness, identify and treat underlying medical issues, as well as support visitation.

A meta-evaluative synthesis of the effects of custodial and community-based offender rehabilitation

By Johann Koehler https://orcid.org/0000-0002-1305-891 j.koehler@lse.ac.uand Friedrich Lösel

We synthesize 53 meta-analyses on the effectiveness of correctional treatment applied to a wide variety of offender groups delivered in either custodial or community-based settings. Those meta-analyses revealed positive overall effects on reoffending of correctional treatment delivered in both settings. However, the treatment setting is also associated with complex moderator effects. With respect to effect size, for most groups, community-based correctional treatment is associated with statistically significant larger reductions in reoffending than treatments delivered in custodial settings. With respect to effect precision, custodial treatments report more consistent effects on reoffending than community-based treatments. The findings extend and develop the insight that treatment flexibility, such as is found among community-based treatments, can optimize program effectiveness. Likewise, the opportunities for monitoring and treatment fidelity that custodial settings enable can homogenize outcomes. Nonetheless, the promising results observed among treatments delivered both inside and outside institutional settings implicate a complex policy tradeoff between prioritizing strong performance and consistent effects.

Corporate offending in Dutch inland shipping: A trajectory analysis

Jelmar J. Meester, Marieke H. A. Kluin, Arjan A. J. Blokland, Wim Huisman, Margje. M. Schuur, and Stephanie I. Wassenburg

Objectives: Describe the prevalence, frequency, and longitudinal development of regulatory offences within Dutch inland shipping on both the ship and business level. Examine whether latent groups with differing trajectories can be distinguished and compare differences between these trajectory groups. Methods: Longitudinal inland shipping inspection data from several inspection agencies are analysed. Lorenz curves and Gini coefficients are used to describe offence distributions. Group-based trajectory modelling is applied to analyse the longitudinal development of regulatory violations of ships and corporations. Between-group comparisons are made using (multivariate) analysis of variance. Results: A skewed distribution of offending on both the ship and business level is found. On both levels of analysis, four trajectory groups display differing developments in the distribution of offending. Although differences in characteristics between trajectory groups were present, effect sizes were small. Conclusions: Disproportionality in corporate offending at both levels of analysis is in constant motion. Regulators need to regularly (re)identify their target groups.

Exploring Carceral Food Systems as Sites of Contestation and Possibility in Canadian Federal Prisons: The Food Services Modernization Initiative 

By Amanda Wilson

Centering the perspectives and lived experiences of incarcerated persons, this article considers the ways food is used as a tool and site of contestation and possibility within federal prisons in Canada. Focusing specifcally on the implementation of and resistance to the Food Services Modernization Initiative, I explore food as “contested terrain” within carceral systems, making visible a range of tactics of resistance employed by incarcerated persons, from testimonials and ofcial complaints to direct collective action. In analyzing these actions and narratives, I refect on the importance of both food justice and prisoner justice to transforming carceral food systems and call for greater acknowledgment of carceral food systems within food movement discourses and campaigns.

Lifting the Veil of Ignorance: Prison Cruelty, Sentencing Theory, and the Failure of Liberal Retributivism

By  Netanel Dagan and Shmuel Baron

Criminologists have criticized the gap between retributive theory and prison realities. In this study, we drew on qualitative findings from the Supreme Court judges of Israel to explore how judicial decision-makers construct the relationship between their retributive theory and their vision of prison life. We found that these judges perceived prison to be a disproportionate and cruel punishment. In responding to prison excessiveness, these judges constructed a “veil of ignorance” between the phases of sentencing and imprisonment by (a) re-theorizing retribution; (b) closing the gap between sentencing and prison, and (c) neutralizing responsibility. The findings shed light on the judiciary’s epistemology of prisons and its meaning for their retributive theory. In conclusion, the boundaries of retributive scholarship should be expanded to include more fully the problematic meaning of prison cruelties for judges’ philosophies and consciousness.

Are Schools in Prison Worth It? The Effects and Economic Returns of Prison Education

By Ben Stickle, Steven Sprick Schuster

Recent expansions in prison school offerings and the re-introduction of the Second Chance Pell Grant have heightened the need for a better understanding of the effectiveness of prison education programs on policy-relevant outcomes. We estimate the effects of various forms of prison education on recidivism, post-release employment, and post-release wages. Using a sample of 152 estimates drawn from 79 papers, we conducted a meta-analysis to estimate the effect of four forms of prison education (adult basic education, secondary, vocational, and college). We find that prison education decreases recidivism and increases post-release employment and wages. The largest effects are experienced by prisoners participating in vocational or college education programs. We also calculate the economic returns on educational investment for prisons and prisoners. We find that each form of education yields large, positive returns due primarily to the high costs of incarceration and, therefore, high benefits to crime avoidance. The returns vary across education types, with vocational education having the highest return per dollar spent ($3.05) and college having the highest positive impact per student participating ($16,908).

A typology of prisoner compliance with the Incentives and Earned Privileges scheme: Theorising the neoliberal self and staff–prisoner relationships

By Zarek Khan

This article is based on interview data (N = 16) collected in a medium security men’s English prison (HMP Wandsworth). It begins with an introduction of the Incentives and Earned Privileges scheme and outlines the amendments to Incentives and Earned Privileges that have transformed prisoners’ requirements for progression during their sentence. As the article demonstrates, the policy alteration increases the need for prisoners to be visibly compliant by staff in order to advance through the scheme; it is no longer sufficient to be invisibly compliant. To this end, I present a typology of visibility that illustrates prisoner compliance and outcomes to the Incentives and Earned Privileges scheme. The article situates the revisions made to Incentives and Earned Privileges against the backdrop of neoliberal informed penal politics. The article concludes by summarising the key theoretical and practical implications of the study.

Growing Rich Off the Fruits of Private Incarceration

By Joseph Hennessy

Mass incarceration is a uniquely American phenomenon. With roots in chattel slavery, modern mass incarceration truly exploded in the latter half of the 20th Century. As Reagan-era politicians advocated for fiscal conservatism on the one hand and heavy-handed responses to crime on the other, private prison pioneers saw an opportunity to derive profit from society’s most vulnerable. Today, private prisons house as much as half of some states’ total prison population, and private prison corporations have demonstrated an insatiable desire to expand their reach. This Note explores the unique social vulnerability of privately incarcerated people through a statutory and judicial lens. It highlights the unique burdens placed on private prisoners that put them at greater risk of personal harm and civil rights violations than their publicly incarcerated counterparts. This Note attempts to incentivize corporate officers of private prisons to maintain safer prisons by imputing to them criminal liability for their subordinates’ crimes. It does so by advocating for the prosecution of unscrupulous corporate officers via the responsible corporate officer doctrine in the 9th Circuit, which has been particularly receptive to expansions of that doctrine.

Who Benefits from Mass Incarceration? A Stratification Economics Approach to the “Collateral Consequences” of Punishment

By Tasseli McKay and William A. “Sandy” Darity Jr.

  A rich empirical literature documents the consequences of mass incarceration for the wealth, health, and safety of Black Americans. Yet it often frames such consequences as a regrettable artifact of racially disproportionate criminal legal system contact, rather than situating the impetus and functioning of the criminal legal system in the wider context of White political and economic domination. Revisiting a quarter century of mass incarceration research through a stratification economics lens, we highlight how mass incarceration shapes Black–White competition for education, employment, and financial resources and contributes to Black–White disparities in well-being. Highlighting persistent research gaps, we propose a research agenda to better understand how mass incarceration contributes to systematic White advantage. To address mass incarceration’s consequences and transform  it arose, we call for legislative and judicial intervention to remedy White hyper-enfranchisement and reparations to eliminate the Black–White wealth gap.

Ensuring Economic Success for Formerly Incarcerated Coloradans

By Tamara Ryan and Cole Anderson   

Upon release, formerly incarcerated people often have few resources to get by while they are seeking employment. They struggle to find work because of criminal stigma, low education levels, and work history gaps. Supporting formerly incarcerated individuals upon their re-entry helps ensure they can take part in the activities needed for employment, such as resume preparation and learning job search skills. One key to improving the likelihood of employment post-incarceration is to ensure returning citizens have adequate financial resources and support to address their immediate needs and allow a focus on gaining employment. Moving more formerly incarcerated people into the workforce presents a massive opportunity for the state. Not having these individuals in the workforce is a lost opportunity for both employers and the state and increases the likelihood they will return to prison or will be rearrested, adding to the cost burden for the state. Key Findings • Formerly incarcerated people are 24% less likely to return to prison when they have acquired new skills and maintained employment during incarceration. • An estimated 6,000 individuals are released from Colorado prisons annually, a number that is roughly equivalent to 20% of the new entrants that are added to the state workforce each year. This number is also 1.5 times larger than Cherry Creek High School, the largest high school in the Denver area. • Breakthrough, a Colorado nonprofit that works with formerly incarcerated individuals, has helped those citizens achieve a 94% employment rate after their release. If Breakthrough’s results could be replicated for all applicable individuals exiting prison, 2,400 more individuals would be employed among each annual prison release cohort. Together those 2,400 individuals would contribute to GDP growth totaling more than $1 billion and a $650 million increase in personal income.  • Colorado’s current 3-year recidivism rate is 28%. Reducing that rate to Breakthrough’s 6% rate would save the state an estimated $55 million annually in recidivism-related costs, realized after the three-year recidivism measurement period. • Inmates working in Colorado’s prisons earn just dollars per day.i Marginally increasing the income inmates can earn while working in prison and on work release programs could help reduce the financial burden to the state through decreased public benefit use and lower recidivism rates. • There is a strong connection between employment and lasting economic benefits for formerly incarcerated individuals. • Colorado currently lacks any data to capture the outcomes, particularly the employment and earnings outcomes, of former inmates. This deficit makes it difficult to gauge the success of post-release programs. • Over the 5-year period prior to the COVID-19 pandemic, more than half of those who recidivated went back to prison because of technical violations such as possessing a firearm or failing to report to a parole officer, not commission of new crimes.  Employment for Returning Citizens Employment is a critical component of successful re-entry into the community after release from incarceration. A study by the Institute of Politics at the John F. Kennedy School of Government found a lack of employment was one of the most significant risk factors affecting successful re-entry.ii Researchers also found community organizations that offer returning citizens assistance with employment were most successful when they provided a holistic approach that included both training and job placement and emphasized high quality jobs with upward mobility potential. Positive benefits of employment include decreased reliance on state assistance, increased self-esteem, a more positive sense of identity, and a life made more stable because of income. Employers also benefit from successful reentry. Hiring formerly incarcerated individuals expands hiring pools at a time when businesses report difficulty finding talent, provides evidence of nondiscriminatory hiring practices, and creates potential tax credit and free bonding service opportunities. Additionally, employers could reduce training costs by hiring individuals who received training while incarcerated. Unfortunately, research shows a felony conviction or incarceration makes individuals significantly less employable. After release, finding a job can take six months or more.iii Providing resources for released individuals to get and keep a job decreases the risk of recidivism because it ensures these citizens are meeting the requirements of parole, contributing to their households, paying off fines or making restitution, and forming the prosocial connections that discourage re-offending. National data shows more than 27% of formerly incarcerated people are unemployed, a number that is higher than the U.S. unemployment rate at any time in history, including the Great Depression. Unemployment is worse for women than men, particularly for formerly incarcerated black women, whose unemployment rate is 43.6%.iv There is a clear connection between unemployment and likelihood to engage in crime. One study found that, among unemployed men in their 30s, more than half had been arrested or convicted of a crime. Additionally, it is important to remember the unemployment rate only measures people who are actively looking for work and does not include discouraged workers who have stopped looking for jobs. When these individuals are included in the calculation, the jobless rate reaches closer to 60%.

Prison Estate Capacity

By U.K. Parliament. House of Commons. Committee of Public Accounts

The Ministry of Justice’s (MoJ’s) and HM Prison and Probation Service’s (HMPPS’s) failure to increase prison capacity in line with demand has led to a prison estate in crisis. Their plans to deliver 20,000 additional prison places in England and Wales by the mid–2020s have been delayed by approximately five years until 2031, and will cost at least £4.2 billion more than planned. MoJ’s and HMPPS’s original plans were unrealistic and they did not work effectively with others in Government to address delivery risks. As at September 2024, HMPPS had delivered just 6,518 additional places, and its plans to deliver the remaining 14,000 are still subject to significant risk. The Lord Chancellor, in her December 2024 announcement of MoJ’s 10–year prison capacity strategy, emphasised the continued need for prison places, as it projected the prison population to increase by an average of 3,000 annually over the coming years. As a result of poor planning and delays, the adult male prison estate was operating at 98.0% to 99.7% occupancy between October 2022 and August 2024 and remains alarmingly full. Overcrowding is endemic, staff are overburdened, and access to services and purposeful activity is poor. The current prison system has had to focus on ensuring there are sufficient places to house prisoners. While the efforts of HMPPS staff to avert disaster are admirable, this state of crisis undermines their efforts to rehabilitate prisoners and reduce reoffending. It also represents poor value for money for the taxpayer, with MoJ and HMPPS unable to make sufficient progress on maintaining existing cells, and needing to rent police cells due to a lack of capacity. MoJ and HMPPS have relied on the early release of prisoners to prevent total gridlock in the criminal justice system. Despite releasing thousands of prisoners early, MoJ still forecasts it will run out of capacity by early 2026. It is relying on the ongoing independent Sentencing Review to prevent this. However, any decisions to divert more people from prison will likely increase pressures on other parts of the system, particularly the Probation Service, which already has issues with staff shortages and high caseloads. This Committee has recently reported on the Crown Court backlog, which is significantly delaying access to justice. Courts and prisons cannot be viewed in isolation: creating sufficient capacity in prisons is vital to enabling a reduction in the courts backlog, and in turn if the courts backlog is reduced this will decrease the number of people on remand. If prisons continue to operate at near–full capacity, this will exacerbate the backlog and stymie efforts to improve efficiency in the justice system.

The impact of incarceration on employment, earnings and tax filing.

By Andrew Garin, Dmitri K. Koustas, Carl McPherson, Samuel Norris, Matthew Pecenco, Evan K. Rose, Yotam Shem-Tov, and Jeffrey Weaver.

We study the effect of incarceration on wages, self-employment, and taxes and transfers in North Carolina and Ohio using two quasi-experimental research designs: discontinuities in sentencing guidelines and random assignment to judges. Across both states, incarceration generates short-term drops in economic activity while individuals remain in prison. As a result, a year-long sentence decreases cumulative earnings over five years by 13%. Beyond five years, however, there is no evidence of lower employment, wage earnings, or self-employment in either state, as well as among defendants with no prior incarceration history. These results suggest that upstream factors, such as other types of criminal justice interactions or pre-existing labor market detachment, are more likely to be the cause of low earnings among the previously incarcerated, who we estimate would earn just $5,000 per year on average if spared a prison sentence.

The State of Solitary: Restrictive Housing and Treatment of Incarcerated Delawareans with Mental Illness

By The Delaware Community Legal Aid Society, Inc. Disabilities Law Program

The Disabilities Law Program (DLP) of Community Legal Aid Society, Inc. (CLASI) serves as Delaware’s Protection and Advocacy (P&A) system, charged with protecting the legal rights of people with physical and mental disabilities. Under federal law, P&A systems have the authority to conduct monitoring and investigative activities in a variety of settings where people with disabilities live and receive services, including correctional facilities. Conditions in correctional facilities are of great concern to CLASI and to other P&A systems around the country, due to the overrepresentation of people with disabilities, including mental illness, in correctional settings. Research also suggests that the experience of incarceration, and of segregation or solitary confinement in particular, can cause mental health problems and also exacerbate existing mental illness. History of CLASI’s Interventions on Behalf of Incarcerated People with Mental Illness Held in Solitary Confinement In 2013, CLASI and the ACLU of Delaware became troubled by reports they were receiving about the placement of individuals with serious mental illness in solitary confinement, meaning that they were confined to cells for at least 22 hours per day, often for extended periods of time. After investigation, in 2015 CLASI, the ACLU, and Pepper Hamilton LLP filed a federal lawsuit, CLASI v. Coupe, against the Delaware Department of Correction (DDOC), which detailed concerns about the treatment of individuals with mental illness placed in restrictive housing environments, including solitary confinement. These concerns included minimal out-of-cell time, lack of access to mental health treatment, and conditions for individuals placed on suicide watch. The parties settled the suit in 2016, and DDOC agreed to make several changes related to the use of restrictive housing. These included: increased mental health staffing; minimum requirements for out-of- cell time; establishing that individuals could not be placed in disciplinary detention for more than 15 consecutive days; requiring a break of at least 15 days between disciplinary detention sanctions; and that no individual classified as seriously mentally ill could be placed in disciplinary detention for any period of time unless they presented an immediate danger and there was no reasonable alternative. The terms of the settlement were effective for five years and concluded in 2021. While the settlement was in effect, CLASI monitored DDOC’s progress by reviewing data, meeting regularly with DDOC leadership, and conducting on-site facility visits with an expert monitor. CLASI’s Recent Monitoring of Correctional Facilities and Treatment of Individuals with Mental Illness In the spring of 2023, CLASI retained two experts to assist its staff in conducting updated monitoring, in order to assess current conditions at DDOC facilities with a specific focus on restrictive housing units, including designated mental health units and units housing individuals in disciplinary detention. CLASI’s monitoring found areas where DDOC appeared to remain in compliance with the policy changes agreed to as part of the CLASI v. Coupe settlement. It also found areas where additional progress had been made, particularly in the implementation of Residential Treatment Units (RTUs) for individuals with mental illness at two facilities. However, the monitoring also identified several major areas of concern. These areas included: suicide prevention practices, the need to expand RTUs, the continuum of mental health services and crisis intervention practices, substance abuse treatment protocols, and the use of punitive point and classification systems and privilege sanctions as “backdoor” methods to restrict and isolate incarcerated individuals, now that more traditional disciplinary detention practices, such as solitary confinement, have been reformed. CLASI is particularly concerned with the need for increased transparency and data sharing to enable it to effectively assess current conditions and carry out its obligations as the P&A. During the monitoring process, DDOC unfortunately denied many of CLASI’s requests for more specific data and information, which made it difficult to assess how DDOC’s current practices compare with those reported while the CLASI v. Coupe settlement was in effect. There is a particular need for more transparency with respect to DDOC’s practices surrounding the use of points-based classification, privilege restrictions, and administrative segregation. CLASI urges DDOC to review the findings and specific recommendations in this report, summarized below, to ensure that incarcerated Delawareans with mental illness are treated fairly and humanely. We also urge DDOC to increase transparency by collecting and making available data regarding the length of restrictions, use of point-based classification, privilege restrictions, and administrative segregation in its facilities.

The Death Row Phenomenon: A Prohibition Against Torture, Cruel, Inhuman and Degrading Treatment or Punishment

By Nkem Adeleye

Several debates on the legitimacy, constitutionality, and acceptability of the death penalty have arisen throughout the years. The death row phenomenon refers to the psychological effects on prisoners of being on death row for a prolonged period while awaiting an imminent execution under harsh conditions of confinement. Having been declared a violation of a customary norm of international law by several international tribunals and national courts, this Article explores the possibility of the death row phenomenon, as a legal concept, becoming widely accepted and ultimately preventing the execution of another category of offenders. The existence of a lack of judicial consensus arising from different standards set by these courts in the determination of what constitutes delay could be an obstacle to this development. This Article suggests that if pursued diligently, the death row phenomenon could become universally accepted as an unacceptable practice and a standard could be set under international law which would become binding upon national courts.

Prevalence of severe mental illness among people in prison across 43 countries: a systematic review and meta-analysis

By Christina Emilian, Noura Al-Juffali, Seena Fazel

Prison populations have been increasing worldwide. Previous studies suggest that there is a high burden of psychiatric morbidity in people in prison, but, to our knowledge, the last published meta-analysis of prevalence is more than a decade old. We aimed to describe the pooled prevalence of depression, psychosis, bipolar disorder, and schizophrenia spectrum disorders for people who are incarcerated. Methods In this updated systematic review and meta-analysis, we searched six databases and grey literature published from database inception until Aug 8, 2024, with no language or geographical restrictions. We included primary quantitative studies that reported the prevalence of depression and psychotic disorders in the unselected prison population, based their diagnoses on clinical examination or from interviews and by the use of validated diagnostic instruments, met standardised criteria of the ICD or the Diagnostic and Statistical Manual of Mental Disorders for the diagnoses, and provided pooled prevalences for psychosis in the previous 6 months and clinical depression in the previous 2 weeks to 1 month. We excluded studies that used selected samples or were only qualitative. We investigated bipolar and schizophrenia spectrum disorders as separate diagnostic subcategories. We synthesised studies using random-effects meta-analysis and explored heterogeneity with meta-regression and subgroup analyses. The protocol is registered with PROSPERO, CRD42022378568. Findings We identified 131 publications reporting the prevalence of mental illness in 58838 people in prison in 43 countries. We estimated that the prevalence of depression was 12·8% (95% CI 11·1–14·6) and for any psychosis was 4·1% (3·6–4·7). For diagnostic subcategories, we found that the prevalence of bipolar disorder was 1·7% (1·0–2·6) and schizophrenia spectrum disorders was 3·6% (1·3–7·1). Between-study heterogeneity was substantial for these estimates (I² 69–97%) with few explanations. However, subgroup analyses revealed that people in prison in lowincome and middle-income countries had higher prevalences for depression (16·7% [95% CI 13·6–20·0]) than in high-income countries (10·8% [9·0–13·0]), and that, for people with psychosis who are incarcerated, psychiatrists were less likely to diagnose (3·5% [2·8–4·3]) than were non-psychiatrists (4·7% [3·9–5·5]). Interpretation Our study indicates that the prevalence of severe mental illness in people who are incarcerated worldwide is considerable. Meeting the treatment needs of people in prison who have mental ill health remains an ongoing challenge for public mental health. More evidence on how to improve the assessment, treatment, and linkage to services on release, which will require more research-friendly prison services, is now needed.

Supporting the Employment Goals of Individuals on Probation: Supportive Services in the Los Angeles County Innovative Employment Solutions Program

By Sophie Shanshory

For individuals on probation and those reentering their communities after incarceration, finding employment is often one of multiple challenges. It can be overwhelming to think about finding and maintaining a job when concerns on an individual’s mind might be How will I get there? What if they find out about my record? Will I make enough money to support myself and my family? Employment is an important factor in reentry but getting to a place where the focus can be on a job, education, or a career requires support in other parts of life as well. In the workforce development field, supportive services are used to respond to a range of needs, encompassing those directly related to and outside of work. These services are considered an important complement to employment-focused services provided through local workforce development systems.

The Los Angeles County Innovative Employment Solutions Program (INVEST) is designed to address the complex range of employment and supportive service needs individuals may have and support them in pursuing their employment and career goals. MDRC, a nonprofit, nonpartisan education and social research organization, is studying INVEST along with several other Los Angeles County–based, criminal legal system and reentry-focused programs. INVEST takes an innovative approach to providing employment and supportive services to people on probation in Los Angeles County. The program prepares staff members to understand the unique needs and challenges of people on probation while at the same time using a flexible spending approach that allows for comprehensive service provision.

A Promising Approach to Coordinated Community-Based Reentry Services

By Michelle S. Manno, Ann Bickerton, Bret Barden, Niko Leiva, Megan Schwartz

Evidence for coordinated reentry—or the coordination of services from multiple community provid­ers—shows that it is a promising approach to supporting people with mental health needs or substance use disorders who are released from correctional facilities. One such program is the Reentry Intensive Case Management Services (RICMS) program. Through a network of 29 community-based providers located across Los Angeles County, the RICMS program links individuals with prior criminal legal system involvement to community health workers—most of whom have lived experience with the criminal legal system, housing instability, or mental health issues. For about one year, the community health workers provide care coordination and help clients navigate the many services and other forms of support available to them.

This report presents findings from the RICMS evaluation, which is part of the Los Angeles County Reentry Integrated Services Project (LA CRISP), a multiyear, multistudy evaluation of services offered by the Los Angeles County Reentry Division that is led by MDRC. The RICMS evaluation includes a process study and outcomes study of the RICMS program that are based on analyses of administrative records and management information system data for people who enrolled in the program between April 2018 and March 2021; a survey of program staff members and man­agers from April 2022; and semistructured interviews with program managers, staff members, and participants that were conducted between June 2019 and August 2022. The study used a nonexperimental approach to compare the health and criminal legal system outcomes of individuals who enrolled and participated in the RICMS program with those of individuals in a matched comparison group who enrolled but did not participate in the program. In the absence of a random­ized controlled trial, this exploratory quasi-experimental analysis provides some initial information about the differences in outcomes that could be due to participation in the program.

Overall, the results suggest that the RICMS approach to coordinated, community-based reentry is promising and could improve the life experiences of program participants, especially by reducing their future contact with the criminal legal system.
