This seventh book in the Prevention Practice Kit illustrates how carefully constructed programs are involved with reaching prevention goals. Using examples and drawing from a clearly presented framework, this book helps readers easily translate concepts of program development and evaluation (PD&E) into doable, practical steps. This book is guided by five tenets: Prevention occurs through programs applied early. A program is comprised of interrelated elements existing within an open system. PD&E involves cyclical phases of planning, implementation and effects, while being infused by the processes of community, collaboration, and cultural relevance. Conducting prevention PD&E relies on both technical and people skills. Effective programs depend on sound processes that are guided by an overall 10-step PD&E in Prevention Model, which include planning the program, implementing process evaluation, and evaluating output. This book is part of the Prevention Practice Kit: Action Guides for Mental Health, a collection of eight books each authored by scholars in the specific field of prevention and edited by Dr. Robert K.
