The program began in 1979, has had more than 500 participants, and currently involves 6 groups of approximately 15 members each. Their recidivism in terms of rearrests over a 5-year period is less than 1 percent. The program uses behavioral techniques to help members acquire effective interpersonal skills. Behavioral change is fostered by a gestalt orientation, cognitive restructuring, and experimentation with 11 specifically defined behaviors. The particularly difficult problem of measuring the effect of a program has been incorporated into the learning process, with observable behaviors providing group leaders and participants with a sound basis for evaluation. 12 references.
