This presentation will include an in-depth description of solitary confinement, a brief history of solitary confinement in the US, and its parallel course with mass incarceration. Following will be a discussion on the human response to solitary confinement and the biopsychosocial targets for intervention. Next will be an exploration of ethical conflicts/dilemmas when working within that environment as a social worker and a focused discussion on how to recognize and resolve the issue of dual loyalty within this setting. We will end the session with a list of ways social workers can join in advocating for people in solitary confinement on a state and federal level. Participants will strengthen their knowledge of solitary confinement as a social and environmental justice issue, learn about the unique ethical issues confronting social workers in this setting, use Reamer's ethical framework to resolve the issue of dual loyalty, and be able to articulate ways they can advocate for those in solitary confinement moving forward.
