Countering violent extremism consists of various prevention and intervention approaches to increase the resilience of communities and individuals to radicalization toward violent extremism, to provide nonviolent avenues for expressing grievances, and to educate communities about the threat of recruitment and radicalization to violence. To explore the application of health approaches in community-level strategies to countering violent extremism and radicalization, the National Academies of Sciences, Engineering, and Medicine held a public workshop in September 2016. Participants explored the evolving threat of violent extremism and radicalization within communities across America, traditional versus health-centered approaches to countering violent extremism and radicalization, and opportunities for cross-sector and interdisciplinary collaboration and learning among domestic and international stakeholders and organizations. This publication summarizes the presentations and discussions from the workshop.

This textbook serves as a guide to design and evaluate evidence-based programs intended to prevent or counter violent extremism (P/CVE). Violent extremism and related hate crimes are problems which confront societies in virtually every region of the world; this text examines how we can prevent or counter violent extremism using a systematic, evidence-based approach. The book, equal parts theoretical, methodological and applied, represents the first science-based guide for understanding “what makes hate,” and how to design and evaluate programs intended to prevent this. Though designed to serve as a primary course textbook, the work can readily serve as a how-to guide for self-study, given its abundant links to freely available online toolkits and templates. As such, it is designed to inform both students and practitioners alike with respect to the management, design, or evaluation of programs intended to prevent or counter violent extremism. Written by a leading social scientist in the field of P/CVE program evaluation, this book is rich in both scientific rigor and examples from the “real world” of research and evaluation dedicated to P/CVE. This book will be essential reading for students of terrorism, preventing or countering violent extremism, political violence, and deradicalization, and highly recommended for students of criminal justice, criminology, and behavioural psychology.

Developmental evaluation (DE) offers a powerful approach to monitoring and supporting social innovations by working in partnership with program decision makers. In this book, eminent authority Michael Quinn Patton shows how to conduct evaluations within a DE framework. Patton draws on insights about complex dynamic systems, uncertainty, nonlinearity, and emergence. He illustrates how DE can be used for a range of purposes: ongoing program development, adapting effective principles of practice to local contexts, generating innovations and taking them to scale, and facilitating rapid response in crisis situations. Students and practicing evaluators will appreciate the book's extensive case examples and stories, cartoons, clear writing style, "closer look" sidebars, and summary tables. Provided is essential guidance for making evaluations useful, practical, and credible in support of social change.
