Are matching funds, or research funds from other outside sources, required for this funding opportunity?

No, matching funds are not required, but supplemental funding is welcomed and encouraged. The ability to leverage other funding for the proposed research project is not a criterion for awarding grants, but it may be a consideration in the decision-making process. Awards may also be used to add a supplemental component to an existing project funded by another source; for example, if there is an existing, funded intervention study taking place in another country, this CFP could fund a supplemental study about translating or adapting the intervention to a U.S. setting.
