Principles of sustainable prevention: Designing scale‐up of School‐wide Positive Behavior Support to promote durable systems

In this article, we provide an overview of School‐wide Positive Behavior Support (SWPBS), an approach to building protective school cultures and preventing the development of problem behavior through instruction, environmental redesign, and attention to systems‐level variables. We define the critical features of SWPBS within a prevention science lens, including identification of its conceptual foundations, proximal mediators of student outcomes, and current research base and goals. Given its evidence of effectiveness, we describe efforts and a research agenda in the area of sustainability of SWPBS, including a description of a proposed model of sustainability and a case study of statewide implementation with steps taken to promote sustained implementation.
