The purpose of this FOA is to seek applications for a Coordinating Center (CC) for Community-Level Interventions for Firearm Violence Prevention (CLIF-VP) Research Network. Members of the CLIF-VP Research Network, including the CC, will work collaboratively with the NIH to develop and test interventions at the community or community organization level that aim to prevent firearm and related violence, injury, and mortality. The CLIF-VP Research Network will include the CC funded under this Cooperative Agreement and up to 10 Research Projects funded under the companion UG3/UH3 Phased Cooperative Agreement FOA, Research on Community Level Interventions for Firearm and Related Violence, Injury, and Mortality Prevention (CLIF-VP) PAR-22-115 . In phase 1 (1-2 years) the Research Projects will need to demonstrate sufficient preparation, feasibility, and capacity for the planned intervention study. Those that pass their milestones will transition into phase 2, during which they will implement their proposed intervention. The CC will provide overarching support and guidance to the network in three domains: (1) administration, coordination, and communication; (2) data, measurement, and analytic support and consultation; and (3) public/stakeholder engagement and dissemination support. It is important that applicants for the CC also read the companion FOA to understand the full mission and structure of the research network.
