The program addresses inmates’ conduct while incarcerated, in the hope that positive changes will carry over when they return to live in their home communities. The basic principle of cognitive theory is that to change behavior, thinking must change. Program participants are consistently reminded that their behavior is their own responsibility. The staff’s function is to provide necessary information and opportunities, and to help offenders see the connection between thinking patterns and their destructive behaviors. Phase 1 is approximately 4 weeks long and offers information about the cognitive process. Restructuring and skill training take place during Phase 2, which may last up to 2 years. Phase 3 is a maintenance period, similar to that of Alcoholics Anonymous, during which offenders self-report on the success or failure of their change efforts. The program includes review sessions during which supervisors and peers monitor one another’s group interaction and document constructive criticism of group behaviors and lesson content.
