There is an urgent need to understand how programming inside prisons can facilitate rehabilitation and reentry processes, especially among men convicted of violent offenses. GRIP (Guiding Rage into Power) is a year-long “Offender Accountability” program presently spreading through the California prison system. GRIP is a group-therapy and trauma-healing program that follows a somatic-awareness-centered model. We use audiovisual data to investigate the sequenced, second-to-second inner workings of what actually constitutes operational excellence in this evidence-based in-prison rehabilitation program. Making use of interaction ritual theory and conversation analysis, we demonstrate how two processes—the diffusion and the redirecting of attentional focus/mood—transpire in GRIP classrooms. The conclusion argues that these two processes may be the “hidden” building blocks, or what is lacking, in countless rehabilitation programs and other social work interventions—both inside and outside of correctional facilities.
