Computational Approaches for Validating Dimensional Constructs of Relevance to Psychopathology (R01 Clinical Trial Optional) | PAR 21 263

Frequently Asked Questions (FAQs)

What is the official title of this grant opportunity?

The opportunity is titled "Computational Approaches for Validating Dimensional Constructs of Relevance to Psychopathology (Clinical Trial Optional)."

Which agency and institute are offering this funding opportunity?

This funding opportunity is offered by the National Institutes of Health (NIH) through the National Institute of Mental Health (NIMH).

What is the Funding Opportunity Number (FOA number)?

The Funding Opportunity Number is PAR 21-263.

What is the CFDA number listed for this opportunity?

The CFDA number listed is 93.242.

What grant mechanism is being used?

This opportunity uses the NIH R01 research project grant mechanism.

Is this a reissue of an earlier announcement?

Yes. This announcement is described as a reissue of an earlier call, RFA-MH-19-242.

What is the overall purpose of this FOA?

The purpose is to strengthen the scientific foundation of the NIMH Research Domain Criteria (RDoC) framework by conducting broad, data-driven validation of RDoC-style dimensional constructs (or closely comparable constructs defined using similar criteria) using computational approaches.

What does NIMH want validated under this FOA?

NIMH is seeking rigorous tests of whether RDoC-style dimensional constructs truly reflect how behavior, brain function, and psychopathology are organized in real-world data.

Does the FOA focus on traditional diagnostic categories?

No. A central theme is moving beyond traditional diagnostic categories and instead testing dimensional constructs that may cut across classic diagnoses.

What kind of research approaches are expected?

The FOA specifically emphasizes computational approaches, including (as examples) modeling, machine learning, and other computational strategies, used to validate constructs within the RDoC matrix.

Is the work expected to be data-driven?

Yes. The FOA calls for broad, data-driven validation efforts aimed at examining the structure of the RDoC matrix as a whole.

Why is NIMH calling for a comprehensive validation effort now?

While the RDoC matrix has been updated over time, NIMH notes that a comprehensive, systematic validation effort exploring the structure of the matrix as a whole has not yet been done.

What aspects of the RDoC matrix structure are applicants expected to examine?

Proposed projects are expected to test whether different behavioral domains separate from one another in measurable ways or whether they blend together more than the matrix implies.

Is there an emphasis on linking constructs to brain circuitry?

Yes. A major emphasis is determining whether domains and constructs depend on distinct neural circuits versus overlapping brain systems.

Are applicants expected to examine relationships among domains, constructs, and subconstructs?

Yes. The FOA highlights mapping relationships among domains, constructs, and more specific subconstructs both statistically (for example, correlational structure) and biologically (for example, shared circuitry or mechanisms).

Do computational and empirical components need to be connected?

Yes. A key expectation is tight integration of computational work with experimental or empirical components, rather than treating them as separate tracks.

How should computational tools be used according to the FOA?

The FOA indicates applicants should show how computational tools will directly inform measurement, experimental design, interpretation of neural and behavioral data, and ultimately the validation (or revision) of constructs.

What kinds of models does NIMH want tested?

The FOA describes a goal of testing integrative models of functioning that can identify patterns of dysregulation linked to psychopathology-related mechanisms that cut across classic diagnoses.

Does the FOA consider that psychopathology-related mechanisms may change over time?

Yes. The FOA notes that mechanisms may shift over time, reflecting developmental change, illness progression, or other dynamic factors.

What is the translational or long-term goal of this research?

NIMH frames the end goal as improving how mental illnesses are classified and treated by establishing which dimensions are separable, which are intertwined, and which share biological substrates, enabling more biologically and behaviorally grounded classification approaches and helping identify treatment targets that may be missed when research is organized strictly around diagnostic labels.

Are clinical trials required?

No. Clinical trials are listed as optional.

Can an application include a clinical trial?

Yes. Because clinical trials are optional, an applicant may propose a study that includes a clinical trial component if it is well-justified and fits the program goals.

What is the listed award ceiling?

The listed award ceiling is $500,000.

What was the original closing date mentioned in the information provided?

The original closing date provided is 2023-09-25.

Should applicants rely only on the date shown here?

No. The information provided notes that applicants should confirm current submission dates and any updates in the official posting and NIH application guides.

Who is eligible to apply in general?

Eligibility is broad and includes state, county, and local governments; public and private institutions of higher education; independent school districts; special district governments; federally recognized Native American tribal governments; tribal organizations (including those other than federally recognized tribal governments); public housing authorities/Indian housing authorities; nonprofits with or without 501(c)(3) status (excluding institutions of higher education where specified); for-profit organizations (other than small businesses); and small businesses.

Are minority-serving institutions specifically mentioned as eligible?

Yes. The FOA explicitly highlights eligibility for Alaska Native and Native Hawaiian Serving Institutions, Asian American Native American Pacific Islander Serving Institutions (AANAPISIs), Hispanic-serving Institutions, Historically Black Colleges and Universities (HBCUs), and Tribally Controlled Colleges and Universities (TCCUs).

Are faith-based or community-based organizations eligible?

Yes. Faith-based or community-based organizations are explicitly listed among eligible applicant categories.

Are U.S. territories or possessions eligible to apply?

Yes. U.S. territories or possessions are listed as eligible applicant categories.

Are foreign (non-U.S.) organizations eligible?

Yes. Non-U.S. entities (foreign organizations) are explicitly included as eligible applicants.

Are tribal governments that are not federally recognized eligible?

Yes. Tribal governments that are not federally recognized are explicitly included among eligible applicant categories.

Why does NIMH emphasize broad eligibility?

The information provided explains that wide eligibility reflects NIMH's interest in drawing from diverse research environments and populations to strengthen the generalizability and real-world relevance of findings.
