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 Psychiatric Rating Scale (BPRS) assessments; and systematic reviews of medical and disciplinary files for 106 randomly selected people in solitary confinement in the Washington State Department 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, or guilt 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 eventually 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.

In the face of the continually worsening COVID-19 pandemic, jails and prisons have become the greatest vectors of community transmission and are a point of heightened crisis and fear within the global crisis. Critical public health tools to mitigate the spread of COVID-19 are medical isolation and quarantine, but use of these tools is complicated in prisons and jails where decades of overuse of punitive solitary confinement is the norm. This has resulted in advocates denouncing the use of any form of isolation and attorneys litigating to end its use. It is essential to clarify the critical differences between punitive solitary confinement and the ethical use of medical isolation and quarantine during a pandemic. By doing so, then all those invested in stopping the spread of COVID-19 in prisons can work together to integrate medically sound, humane forms of medical isolation and quarantine that follow community standards of care rather than punitive forms of solitary confinement to manage COVID-19.
