Book excerpt: Demonstrating that public health and prevention program development is as much art as science, this book brings together expert program developers to offer practical guidance and principles in developing effective behavior-change curricula. Feinberg and the team of experienced contributors cover evidence-based programs addressing a range of physical, mental, and behavioral health problems, including ones targeting families, specific populations, and developmental stages. The contributors describe their own professional journeys and decisions in creating, refining, testing, and disseminating a range of programs and strategies. Readers will learn about selecting change-promoting targets based on existing research; developing and creating effective and engaging content; considering implementation and dissemination contexts in the development process; and revising, refining, expanding, abbreviating, and adapting a curriculum across multiple iterations. Designing Evidence-Based Public Health and Prevention Programs is essential reading for prevention scientists, prevention practitioners, and program developers in community agencies. It also provides a unique resource for graduate students and postgraduates in family sciences, developmental psychology, clinical psychology, social work, education, nursing, public health, and counselling.
