NIMH Investigator-Initiated Research

NIMH R01/R21/R03

Funds investigator-led mental health science in the United States through established and exploratory research projects.

The National Institute of Mental Health (NIMH) funds investigator-initiated research through the standard NIH research project grant mechanisms — primarily R01, R21, R03, R15, and R34 — submitted to parent Program Announcements open to any scientifically meritorious mental health topic. NIMH's extramural portfolio covers basic, translational, and clinical research on depression, anxiety disorders, bipolar disorder, schizophrenia, post-traumatic stress disorder, suicide, and related neuroscience. In FY2023, NIMH awarded 579 new and competing grants at an approximately 22 percent success rate across all extramural mechanisms, out of more than 3,000 active research grants and contracts. The institute's FY2025 budget request was $2.5 billion in constant FY2017 dollars, and the BRAIN Initiative transferred an additional $45.5 million to NIMH for neurotechnology research that year.

Eligible organizations include US and international universities, hospitals, and research institutions; principal investigators must hold a position at an eligible institution. The modular R01 cap is $250,000 per year in direct costs (NIH-wide rule), and applications for larger budgets require detailed non-modular budgets. Standard R01 receipt dates run on three cycles per year (February, June, and October). NIMH operates ALACRITY Research Centers (P50) for accelerating reach and impact of treatments, and the Early Psychosis Intervention Network (EPINET) through U-series cooperative agreements — separate NOFOs with their own deadlines govern those programs.

Applicants are advised to contact the relevant NIMH division program officer before submitting to confirm fit with current institute priorities and to identify the correct parent NOFO. Applying to a NOFO that does not accept the research type (e.g., clinical trial versus basic) results in administrative withdrawal before peer review. Applicants should note that NIMH's website carries a standing disclaimer that some content is not being updated regularly due to ongoing HHS and NIH organizational restructuring; grants.nih.gov and eRA Commons remain the authoritative sources for current receipt dates and paylines.
