of Problem Behaviors
Perhaps the most critical principle of intervention in positive behavior support (PBS) is that a plan of support should be based on a functional understanding of the problem behavior that caused the plan to be developed in the first place. The behavior support plan is not arbitrary; it is not photocopied from generic behavior management manuals; and its components are not dictated by previous experience or interventions with other individuals. Rather, the plan is based on the existing science of human behavior and, most importantly, on information that is derived from a functional assessment of the individual's identified problem behavior. The synthesis of the functional assessment information constitutes the functional understanding that is the foundation of the support plan. The purpose of this chapter is to describe the concepts and assumptions that serve as the basis for the functional assessment process and PBS.
Our aim in this chapter is to present a simple conceptual framework for understanding how problem behaviors may be governed by events in
