Review of Prevention Programming Undertaken by Allies Abroad to Identify Promising Practices Report

While the threat of terrorism is not a new phenomenon, the United States, along with many of its allies, face a heightened threat environment that requires a coordinated response from policy, operations, and research partners. As communities continue to develop and implement prevention programming, it is vital to understand what is working, what is not, and what is promising. Although there is limited research identifying evidence-based practices, decades of programming have identified lessons in the approaches, activities, and factors that may affect the success of prevention programming. To help close this gap, the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) commissioned a study by RTI International to identify promising practices based on their experience across government, academic, and nongovernmental organizations. This study was narrowed to three domains: 1) community engagement programs, 2) deradicalization and disengagement programs in criminal legal systems, and 3) DD programs in the community.
