In this chapter we define behavioral systems and behavioral systems analysis with examples of contexts where behavioral systems may be used to fulfill ethical obligations of protecting consumers and providing high quality care. Specifically, we describe a systems approach to incorporate consumer choice into treatment decisions, monitoring adverse events in behavioral treatment, and develop and use consumer feedback loops to improve practice and standards. Where appropriate, we provide examples behavioral systems in visual or table format to help further illustrate the concept of a behavioral system to help support ethical behavior in practice.
