Dr. Harry Wexler walks through the past and current research developments on the efficacy of Therapeutic Communities in prisons. A timeline from the 1950s to present details how the Therapeutic Community model developed in prisons, and what research efforts supported that development. Wexler discusses a breadth of topics including: the evidence that prison treatment alone is insufficient for long-term change, and the importance of aftercare; the benefits and potential problems of manual-based treatment; the need for incentives; the importance of bridging TC members and facilitators with their outside communities; and the promising new research of TCs in maximum-security prisons and the potential of reducing violence among their prisoners.
