Check out Lifetime Lockdown: How Isolation Conditions Impact Prisoner Reentry.
From the executive summary: “This report represents the first effort to directly link conditions in Arizona’s supermax prisons with the state’s high recidivism rate. Because the statistical evidence of this link is already available, the basis of this report is qualitative research conducted by an anthropologist, Dr. Brackette F. Williams. Dr. Williams interviewed newly released individuals who had spent a significant portion of their time in prison in supermax facilities. This research demonstrates the “why” and “how” of this causal relationship, illustrating the impacts of long-term solitary confinement on actual re-entry experiences.”
