To address targeted violence at military installations, the Defense Personnel and Security Research Center (PERSEREC) developed a targeted violence prevention program plan and corresponding evaluation plan. The program plan uses existing installation resources (e.g., clinicians, chaplains, financial staff, and social workers) and resources in the local civilian community. It allows installations to adapt or add activities to existing local procedures and practices. The evaluation plan guides the installation as it assesses the program plan’s implementation and effectiveness. This research note describes the development of the program plan and corresponding evaluation plan.
