In March 2025, the New York State (NYS) Department of Correction and Community Supervision (DOCCS) and correction officers reached an agreement to end a 22-day unauthorized work stoppage.1 That agreement includes three terms related to the Humane Alternatives to Long-Term Solitary Confinement Act (HALT), a law that limits and regulates DOCCS’ use of segregated confinement: (1) a 90-day suspension of the law’s programming provisions, (2) a directive for facility administrators to prioritize suspending general population programs over HALT-mandated ones on days with high staff vacancies, and (3) the establishment of a committee to recommend changes to the law (HALT Committee). Before these events unfolded, the Correctional Association of New York (CANY) set out to examine two interrelated issues: compliance with and perceptions of HALT within state correctional facilities. In March 2023, CANY published a report examining the first eight months of HALT’s implementation. Building on that earlier work, this report examines trends in DOCCS’ use of segregated confinement, compliance with key provisions of the law, and perceptions of HALT’s impact on work and life in prison. More specifically, this report covers the period from January 2023 to July 2024 but occasionally includes data from the year before and months after HALT was implemented for comparison. The analysis draws from one-on-one interviews, stakeholder meetings, and administrative data. It is presented in three sections: Part I: Analysis of DOCCS’ Data on the Special Housing Unit (SHU) and Rehabilitative Residential Unit (RRU), Part II: Implementing HALT, and Part III: Living and Working with HALT. The report finds that, since HALT was implemented, the number of people isolated from the general population for disciplinary reasons, either in a SHU or RRU, has increased. While the SHU and RRU are meant to serve distinct purposes, the law’s implementation—constrained by existing infrastructure, staffing challenges, and, at times, DOCCS’ interpretation—has led to gaps in compliance that blur the distinction between the two units.

In a given year, one in five people incarcerated in the U.S. prisons is locked in solitary confinement. We study solitary confinement along three dimensions of penal harm: (1) material deprivation, (2) social isolation, and (3) psychological distress. Data from a longitudinal survey of incarcerated men who are interviewed at baseline in solitary confinement are used to contrast the most extreme form of penal custody with general prison conditions observed at a follow-up interview. Solitary confinement is associated with extreme material deprivation and social isolation that accompanies psychological distress. Distress is greatest for those with histories of mental illness. Inactivity and feelings of dehumanization revealed in qualitative interviews help explain the distress of extreme isolation, lending empirical support to legal arguments that solitary confinement threatens human dignity.

This article deals with the right to make requests and complaints (RCs) inside Spanish prisons. It discusses the European Prison Rules and the principles set forward by the European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment (CPT), examining how the Spanish system respects these. It then introduces the RCs system in Spain. Through research carried out in four prisons, interviews with the directors and with 21 inmates and taking as an example one prison, we were able to discover that the number of requests in one year is 55,000. This result reveals the formalised character of Spanish prisons and raises the question as to how to respond to RCs inside prison. The last part of the article draws on interviews with three Penitentiary Judges and discusses their role in reviewing RCs. In our analysis of 626 of the final decisions we found that 98.6% were denied. Finally, the article provides some explanations for this result and questions whether judges can be said to provide an effective remedy in such cases.

We examine how solitary confinement correlates with self-reported adverse physical health outcomes, and how such outcomes extend the understanding of the health disparities associated with incarceration. Using a mixed methods approach, we find that solitary confinement is associated not just with mental, but also with physical health problems. Given the disproportionate use of solitary among incarcerated people of color, these symptoms are most likely to affect those populations. Drawing from a random sample of prisoners (n = 106) in long-term solitary confinement in the Washington State Department of Corrections in 2017, we conducted semi-structured, in-depth interviews; Brief Psychiatric Rating Scale (BPRS) assessments; and systematic reviews of medical and disciplinary files for these subjects. We also conducted a paper survey of the entire long-term solitary confinement population (n = 225 respondents) and analyzed administrative data for the entire population of prisoners in the state in 2017 (n = 17,943). Results reflect qualitative content and descriptive statistical analysis. BPRS scores reflect clinically significant somatic concerns in 15% of sample. Objective specification of medical conditions is generally elusive, but that, itself, is a highly informative finding. Using subjective reports, we specify and analyze a range of physical symptoms experienced in solitary confinement: (1) skin irritations and weight fluctuation associated with the restrictive conditions of solitary confinement; (2) un-treated and mis-treated chronic conditions associated with the restrictive policies of solitary confinement; (3) musculoskeletal pain exacerbated by both restrictive conditions and policies. Administrative data analyses reveal disproportionate rates of racial/ethnic minorities in solitary confinement. This analysis raises the stakes for future studies to evaluate comparative prevalence of objective medical diagnoses and potential causal mechanisms for the physical symptoms specified here, and for understanding differential use of solitary confinement and its medically harmful sequelae.

Objectives. To specify symptoms and measure prevalence of psychological distress among incarcerated people in long-term solitary confinement. Methods. We gathered data via semistructured, in-depth interviews; Brief PsychiatricRating Scale (BPRS) assessments; and systematic reviews of medical and disciplinary filesfor 106 randomly selected people in solitary confinement in the Washington StateDepartment of Corrections in 2017. We performed 1-year follow-up interviews and BPRS assessments with 80 of these incarcerated people, and we present the results of our qualitative content analysis and descriptive statistics.Results. BPRS results showed clinically significant symptoms of depression, anxiety, orguilt among half of our research sample. Administrative data showed disproportionately high rates of serious mental illness and self-harming behavior compared with general prison populations. Interview content analysis revealed additional symptoms, including social isolation, loss of identity, and sensory hypersensitivity.Conclusions. Our coordinated study of rating scale, interview, and administrative data illustrates the public health crisis of solitary confinement. Because 95% or more of all incarcerated people, including those who experienced solitary confinement, are even-tually released, understanding disproportionate psychopathology matters for developing prevention policies and addressing the unique needs of people who have experienced solitary confinement, an extreme element of mass incarceration.

The literature on the prevalence and causes of punishment has been dominated by research into the United States. Yet most of the world's prisoners live elsewhere, and the United States is no longer the country with the world's highest incarceration rate. This article considers what we know about the prevalence and causes of incarceration around the world. We focus on three features of incarceration: its level, inequality, and severity. Existing comparative research offers many insights, but we identify methodological and theoretical shortcomings. Quantitative scholars are still content to draw causal inferences from correlations, partly because (like qualitative scholars) they are often limited to studying the present and the developed world. More data will allow better inferences. We close by defending the goal of building precise and generalizable theories of punishment.

Question What is the association between exposures to extreme heat and suicide-watch incidents in a state prison system without air-conditioned living units?

Findings This case series of 6576 facility-incarceration days found that extreme heat was significantly associated with a 30% increase in the incident rate of daily suicide-watch incidents.

Meaning These findings suggest that extreme heat may increase vulnerabilities to situations that lead to suicide-watch placements for incarcerated people, bolstering calls for heat mitigation and decarceral interventions to assuage heat-induced harms among incarcerated populations.

Importance Extreme heat poses a distinct risk to the 2.1 million incarcerated people in the United States, who have disparately high rates of behavioral health conditions. Suicide is a leading cause of death among people in prisons.

Objective To examine associations of extreme heat, solitary confinement, and an indicator of suicidal behaviors among incarcerated men in a Deep South US prison system.

Design, Setting, and Participants This longitudinal case series panel study included adult men in prisons in Louisiana, a state with one of the largest prison systems in the United States that has been engaged in litigation due to lack of air conditioning and extreme heat. The unit of analysis was prison facility-days. A facility-level data set was created by merging administrative data files, which included demographic characteristics, health classification, housing location and movement, disciplinary records, and involvement in suicide-watch incidents for all incarcerated men in Louisiana during the observation period. Individual-level variables were aggregated to facility-days to merge in daily maximum heat index data from the US Local Climatological Data, which were linked to the zip codes of prisons. The observation period was January 1, 2015, to December 31, 2017. Data set construction occurred from August 2020 to September 2022, and analysis was conducted from December 2022 to February 2023.

Exposure The focal exposure was extreme heat days. Daily maximum heat index data were categorized into 6 bins (<30 °F, 30-39 °F, 40-49 °F, 50-59 °F, 70-79 °F, and ≥80 °F) and as an indicator for any facility-day where the maximum heat index exceeded the 90th percentile of heat indices for total days in observation period. Conditional fixed-effects negative binomial regression models were used to calculate incident rate ratios to test associations between extreme heat and suicide watch incidents, while controlling for covariates.

Main Outcomes and Measures The focal outcome was daily count of suicide watch incidents that were recorded in a carceral system database. Covariates included daily percentages of incarcerated persons at each prison with serious mental illness diagnosis, daily rate of solitary confinement, and total facility population.

Results The sample of 6 state-operated prisons provided 6576 facility-days for the analysis. Results suggest a dose-responsive association between extreme heat and daily counts of suicide-watch incidents; compared with days with temperatures between 60 and 69 °F, the rate of daily suicide incidents increased by 29% when the heat index reached the level of caution (ie, 80-89 °F) and by 36% when reaching extreme caution (90-103 °F) (80-89 °F: incidence rate ratio [IRR], 1.29; 95% CI, 1.17-1.43; P < .001; 90-103 °F: IRR, 1.36; 95% CI, 1.15-1.61; P  95% CI, 1.18-1.45; P < .001).

Conclusions and Relevance Findings suggest an association between extreme heat and an indicator of suicidality among an incarcerated sample, contribute to an emerging literature exploring linkages between climatological events and health outcomes in prisons, and may have implications for legal interventions and advocacy seeking to abate heat-induced morbidity and mortality in carceral contexts.

There is considerable speculation that prisons are a breeding ground for radicalization. These concerns take on added significance in the era of mass incarceration in the United States, where 1.5 million people are held in state or federal prisons and around 600,000 people are released from prison annually. Prior research relies primarily on the speculation of prison officials, media representations, and/or cross-sectional designs to understand the imprisonment-extremism nexus. We develop a tripartite theoretical model to examine continuity and change in activism and radicalism intentions upon leaving prison. We test these models using data from a large probability sample of prisoners (N = 802) in Texas interviewed in the week preceding their release from prison and then re-interviewed 10 months later using a validated scale of activism and radicalism intentions. We arrive at three primary conclusions. First, levels of activism decline upon reentry to the community (d = -0.30, p < .01), while levels of radicalism largely remain unchanged (d = -0.08, p = .28). What is learned and practiced in prison appears to quickly lose its vitality on the street. Second, salient groups and organizations fell in importance after leaving prison, including country, race/ethnicity, and religion, suggesting former prisoners are occupied by other endeavors. Finally, while we identify few correlates of changes in extremist intentions, higher levels of legal cynicism in prison were associated with increases in both activism and radicalism intentions after release from prison. Efforts designed to improve legal orientations could lessen intentions to support non-violent and violent extremist actions. These results point to an imprisonment-extremism nexus that is diminished largely by the realities of prisoner reentry.

Question: How commonly are medications for chronic conditions used in jails and state prisons compared with community settings in the US? Findings In this cross-sectional descriptive study of incarcerated and non-incarcerated populations in the US from 2018 to 2020, use of prescription medications for chronic conditions was consistently lower in jails and state prisons compared with community settings. After adjusting for disease prevalence, the relative disparity was 2.9-fold for diabetes, 5.5-fold for asthma, 2.4-fold for hypertension, 1.9-fold for hepatitis B or C, 3.0-fold for human immunodeficiency virus, 4.1-fold for depression, and 4.1-fold for severe mental illness. Meaning This analysis suggests that prescription medications for chronic conditions may be substantially underused in jails and state prisons in the US relative to the non-incarcerated population, after accounting for the differential burden of disease in these settings.

During a summer marked by record-setting heat waves, the state of New Jersey housed roughly 3,500 people in prison housing units with no air conditioning. About 3,000 correctional police officers were also assigned to these non-temperature-controlled spaces. On July and August site visits, the Office of the Corrections Ombudsperson measured temperatures in 80 percent of the state’s populated housing units and conducted brief interviews with incarcerated individuals and staff. Temperatures inside individual prison cells were as high as 88 degrees Fahrenheit during the July site visit and 94 degrees during the August visit. People in state prisons described temperatures in their living spaces as “unbearable,” “beyond hot,” and “like Hell.” The Ombuds office heard reports of people engaging in assaultive behavior in order to be transferred to air-conditioned disciplinary housing assignments. The office also heard reports from staff and labor leaders that high heat increased irritability and slowed responses to prison security incidents. Three prisons—Bayside State Prison, East Jersey State Prison, and Garden State Correctional Facility— account for more than three-quarters of the state’s non-air-conditioned prison beds. Another three prisons, including the two largest facilities, are fully air-conditioned. And the remaining three state prisons have a mix of temperature-controlled and non-temperature-controlled housing units. Because people detained in prison facilities cannot leave of their own accord and have limited control over their movement, possessions, and environment, the state assumes a responsibility for their humane treatment, including a responsibility to protect them from potential harms associated with extended exposure to heat and cold. Department of Corrections executive and facility leaders have taken proactive and reactive steps to mitigate the heat and have worked closely with the Office of the Corrections Ombudsperson to address areas of concern. They should be applauded for their efforts, utilizing the resources they have, to reduce the risks of heat stroke and other heat-related illnesses and security risks. These risks, however, will continue to surface each summer absent state appropriations for major building repairs.
