This guide presents a capacity building framework and process for demonstrating and documenting prevention outcomes. Achieving Outcomes was developed by the Center for Substance Abuse Prevention (CSAP) in response to requests from the prevention field for guidance in selecting and implementing science-based prevention programs. The guide is organized conceptually around a framework called a program logic model. The components of the model are the five chapters of the guide: (1) needs and assets assessment, (2) capacity building, (3) program selection, (4) implementation and assessment, and (5) final evaluation. Each chapter is graphically represented as well by a component logic model, or conceptual map, of the activities that make up the chapter. It is hoped that the guide will keep practitioners focused on authentic goals and objectives, enabling them to select an appropriate intervention that--when properly implemented, measured, and evaluated--will lead to behavioral change and, ultimately, substance abuse prevention and/or reduction. This guide seeks to help ensure that what practitioners are doing in the prevention field leads to measurable change for their chosen population, policy, or neighborhood of interest.
