The Translating Socioenvironmental Influences on Neurocognitive Development and Addiction Risk (TranSINDA) (R34 Clinical Trial Not Allowed) funding program from the National Institutes of Health (NIH) supports research projects of limited scope proposing a set of planning activities that will lay the groundwork for a scientific project aiming to use animal models and longitudinal research designs to elucidate mechanisms mediating the impact of the early-life social environment on neurobehavioral development and the emergence of SUD risk-relevant behaviors. This planning grant funding opportunity will support the planning and development of the research framework, design, and approach; including activities that will establish feasibility, validity, and/or other technically qualifying results that, if successful, would support a competitive application for an R01 or equivalent NIH research award. Applications are open to researchers in the USA and worldwide. Applicants may apply for up to 450,000 USD for over 2 years. Opportunity ID: RFA-DA-24-019. Letters of intent are due October 10, 2023. Full applications are due November 9, 2023.
