COSA method and theory

COSA has been developed as a practice based approach, out of a strong belief in ethical and practical principles and was less derived from theoretical insights into sex offender relapse prevention. The call for ‘evidence based practice’, however, is growing in social intervention policies and funding, which means that interventions more and more have to provide proof that money has been well spent and goals are being met. A first step is to provide a rationale for the COSA method.
