This document outlines an 8-session group psychoeducation program to teach inmates with serious mental illness skills to manage negativity in prison. The program aims to help inmates examine how their negativity can be debilitating and develop coping skills. It is presented as a structured class format rather than traditional group therapy. The goals are to help inmates adjust to prison rather than expecting the environment to adjust to them. Each session builds on the last to cumulatively develop a positive learning experience and new skills for managing stressors, identifying strengths, making decisions, and minimizing the impact of negative situations. The program is intended to be used alongside other mental health treatments to comprehensively address negativity that stems from incarceration.
