This Request for Information (RFI) issued by the United States Agency for International Development (USAID), numbered 7200AA23RFI00008, seeks input from organizations for a forthcoming Global Health Social and Behavior Change (SBC) activity. The aim is to enhance local leadership and ownership of high-quality, evidence-informed SBC programs to improve health outcomes over a projected five-year period. The document emphasizes that this RFI is for market research purposes only and does not guarantee future solicitations or funding. The background section outlines USAID's ongoing investment in SBC programming, which integrates various disciplines to improve behaviors and norms essential for health and development. Challenges identified include varying capacities among local actors, lack of commitment to SBC, and inadequate evaluation systems. USAID is soliciting feedback on barriers and facilitators of SBC programming, local priorities, and strategies for strengthening local capacities. Respondents are encouraged to provide concise responses that address specific questions posed but are not required to answer all questions. The overarching goal is to refine the design of the SBC activity, ensuring it is effectively tailored to local contexts and capable of fostering sustainable health improvements.
