The National Institutes of Health (NIH) is offering a funding opportunity for Pilot Effectiveness Trials for Treatment, Preventive, and Services Interventions (R34 Clinical Trial Required). This initiative aims to support pilot studies that evaluate the effectiveness of preventive and therapeutic interventions with established efficacy, focusing on broader populations and community practice settings, while also exploring innovative service interventions to enhance mental health outcomes. The program emphasizes the importance of understanding the empirical mechanisms behind intervention benefits and encourages collaboration with stakeholders to ensure practical implementation. With an anticipated funding amount of $27 million available for FY 2022, applicants can request up to $450,000 in direct costs over a project duration of three years. Interested parties should submit their applications by October 15, 2024, and can reach out to the NIH OER Webmaster at FBOWebmaster@OD.NIH.GOV for further inquiries.
