This chapter presents a conceptual framework of the treatment process in the therapeutic community (TC). The essential elements of the perspective, model, and method are reformulated into the three broad components of the treatment process. First, the multiple interventions in the process consist of the program structure, the people, daily regimen of activities, and social interactions in the TC. Second, individual change is multidimensional, described in terms of objective social and psychological domains as well as subjective perceptions and experiences. Third, social and behavioral learning principles and subjective mechanisms such as critical experiences, perceptions, and internalization are integral in the process itself. The main elements of the treatment process in the TC have been described in terms of community interventions, behavioral dimensions, and the essential perceptions and experiences. All change in the TC is viewed from a behavioral orientation in terms of learning and training.
