Notice of Funding Opportunity Description Research Scope and Objectives Potential applicants are strongly encouraged to consult with NIMH staff as early as possible when developing plans for an application. This early contact will provide an opportunity to clarify NIH policies and guidelines and help to identify whether the proposed project is consistent with NIMH program priorities and NOFO goals.

For the NIMH, areas of high priority include, but are not limited to: Identification of neurobiological and psychological risk and protective factors that may serve as modifiable targets in future mental illness intervention development. Studies investigating the role of social comparison and risk for psychopathology, including but not limited to, peer social processes, body image comparison, and comparison with influencers.

Studies of novel technologies and their intersection with mental health, including artificial intelligence, virtual reality, smart glasses, and novel smartphone and wearable technologies.

Services and intervention Research that leverages partnerships with purveyors of mental health-related information aimed at providing accurate content (i.e., psychoeducation) and embedding tools for online screening for early detection and strategies to promote referral, help-seeking, and treatment engagement.

For applications that involve optimizing and testing interventions for prevention, treatment, or for promoting help-seeking and engagement in services , research designs must be consistent with the NIMH experimental therapeutics approach . Trial designs should include an evaluation of at least one hypothesized mechanism of action that is presumed to account for intervention effectiveness.

Applications must specify (1) at least one hypothesized mechanism of action for the intervention and/or implementation strategy, (2) measurement plans to feasibly assess the mechanism of action and primary outcomes, and (3) an analytic plan designed to evaluate both changes in the mechanism of action and the association between changes in the mechanism of action and the primary outcome(s).

The nature of the proposed mechanism will vary depending on the nature of the intervention (e.g., for preventive and therapeutic interventions, mechanisms include factors that have been empirically associated with mental disorder risk, etiology, maintenance, or severity). Applications Not Responsive to this NOFO. The following types of studies are not responsive to this NOFO.

Applications proposing such studies will be considered non-responsive and will not be reviewed or considered for funding. Applications that are not focused on adolescence, defined broadly as 10-20 years of age. Applications without theoretical and methodological considerations of mental illness.

Applications that only measure duration of time spent on screens or digital communications. Applications proposing animal research.

Applications that propose preventive, therapeutic, or services intervention without an evaluation of the mechanism of action and its impact on the primary outcomes, including the following components: (1) specified mechanisms of action, (2) measurement plans designed to assess the mechanism of action and clinical outcomes in the intervention setting, and (3) analytic plan for evaluating whether intervention-induced mechanisms of action are associated with outcomes.

Applications that propose psychoeducation, health literacy, and referral interventions without explicitly examining the impact on service access, engagement, quality and/or outcomes of care. The NIMH has published updated policies and guidance for investigators regarding human research protection and clinical research data and safety monitoring ( NOT-MH-19-027 ).

Resource Sharing Plan : Individuals are required to comply with the instructions for the Resource Sharing Plans as provided in the How to Apply- Application Guide.

All instructions in the How to Apply-Application Guide must be followed, with the following additional instructions: All applicants planning research (funded or conducted in whole or in part by NIH) that results in the generation of scientific data are required to comply with the instructions for the Data Management and Sharing Plan.

All applications, regardless of the amount of direct costs requested for any one year, must address a Data Management and Sharing Plan. To advance the goal of advancing research through widespread data sharing among researchers, investigators funded by NIMH under this NOFO are expected to share those data via the National Institute of Mental Health Data Archive (NDA; see NOT-MH-23-100 ).

Established by the NIH, NDA is a secure informatics platform for scientific collaboration and data-sharing that enables the effective communication of detailed research data, tools, and supporting documentation. NDA links data across research projects through its Global Unique Identifier (GUID) and Data Dictionary technology. Investigators funded under this NOFO are expected to use these technologies to submit data to NDA.

To accomplish this objective, it will be important to formulate a) an enrollment strategy that will obtain the information necessary to generate a GUID for each participant, and b) a budget strategy that will cover the costs of data submission.

The NDA website provides two tools to help investigators develop appropriate strategies: 1) t he NDA Data Submission Cost Model which offers a customizable Excel worksheet that includes tasks and hours for the Program Director/Principal Investigator and Data Manager to budget for data sharing; and 2) plain language text to be considered in your informed consent available from the NDA's Data Contribution page .

Investigators are expected to certify the quality of all data generated by grants funded under this NOFO prior to submission to NDA and review their data for accuracy after submission.

Submission of descriptive/raw data is expected semi-annually (every January 15 and July 15); submission of all other data is expected at the time of publication, or prior to the end of the grant, whichever occurs first (see NDA Sharing Regimen for more information); Investigators are expected to share results, positive and negative, specific to the cohorts and outcome measures studied.

For more guidance on submitting data to NDA, refer to the NDA Data Management and Sharing Plan on the NDA website . NDA staff will work with investigators to help them submit data types not yet defined in the NDA Data Dictionary . Appendix: Only limited Appendix materials are allowed.

Follow all instructions for the Appendix as described in the How to Apply- Application Guide. No publications or other material, with the exception of blank questionnaires or blank surveys, may be included in the Appendix.

PHS Human Subjects and Clinical Trials Information When involving human subjects research, clinical research, and/or NIH-defined clinical trials (and when applicable, clinical trials research experience) follow all instructions for the PHS Human Subjects and Clinical Trials Information form in the How to Apply- Application Guide, with the following additional instructions: If you answered “Yes” to the question “Are Human Subjects Involved?

5. Intergovernmental Review (E. O.

12372) This initiative is not subject to intergovernmental review. Use of Common Data Elements in NIH-funded Research Many NIH ICs encourage the use of common data elements (CDEs) in basic, clinical, and applied research, patient registries, and other human subject research to facilitate broader and more effective use of data and advance research across studies.

CDEs are data elements that have been identified and defined for use in multiple data sets across different studies. Use of CDEs can facilitate data sharing and standardization to improve data quality and enable data integration from multiple studies and sources, including electronic health records.

NIH ICs have identified CDEs for many clinical domains (e.g., neurological disease), types of studies (e.g. genome-wide association studies (GWAS)), types of outcomes (e.g., patient-reported outcomes), and patient registries (e.g., the Global Rare Diseases Patient Registry and Data Repository). NIH has established a Common Data Element (CDE) Resource Portal" ( http://cde. nih.

gov/ ) to assist investigators in identifying NIH-supported CDEs when developing protocols, case report forms, and other instruments for data collection. The Portal provides guidance about and access to NIH-supported CDE initiatives and other tools and resources for the appropriate use of CDEs and data standards in NIH-funded research.

Investigators are encouraged to consult the Portal and describe in their applications any use they will make of NIH-supported CDEs in their projects. NIMH expects investigators for this funding announcement to collect Common Data Elements (CDEs) for mental health human subjects research.

Unless NIMH stipulates otherwise during the negotiation of the terms and conditions of a grant award, this Notice applies to all grant applications involving human research participants. The necessary funds for collecting and submitting these CDE data from all research participants to the NIMH Data Archive (NDA) should be included in the requested budget. A cost estimator ( https://nda.

nih. gov/ndarpublicweb/Documents/NDA_Data_Submission_Costs. xlsx ) is available to facilitate the calculation of these costs.

NIMH may seek further information regarding CDEs prior to award. Additional information about CDEs can be found at the NIMH webpage on Data Management and Sharing for Applicants and Awardees. All NIH awards are subject to the terms and conditions, cost principles, and other considerations described in the NIH Grants Policy Statement .

Pre-award costs are allowable only as described in the NIH Grants Policy Statement Section 7. 9. 1 Selected Items of Cost.

Post Submission Materials Applicants are required to follow the instructions for post-submission materials, as described in the policy Section V. Application Review Information Only the review criteria described below will be considered in the review process. Applications submitted to the NIH in support of the NIH mission are evaluated for scientific and technical merit through the NIH peer review system.

Reviewers will provide an overall impact score to reflect their assessment of the likelihood for the project to exert a sustained, powerful influence on the research field(s) involved, in consideration of the following scored review criteria and additional review criteria (as applicable for the project proposed). An application does not need to be strong in all categories to be judged likely to have a major scientific impact.

Reviewers will consider Factors 1, 2 and 3 in the determination of scientific merit, and in providing an overall impact score. In addition, Factors 1 and 2 will each receive a separate factor score. Factor 1.

Importance of the Research (Significance and Innovation) Evaluate the importance of the proposed research in the context of current scientific challenges and opportunities, either for advancing knowledge within the field, or more broadly. Assess whether the application addresses an important gap in knowledge in the field, would solve a critical problem, or create a valuable conceptual or technical advance.

Evaluate the rationale for undertaking the study, the rigor of the scientific background for the work (e.g., prior literature and/or preliminary data) and whether the scientific background justifies the proposed study. Evaluate the extent to which innovation influences the importance of undertaking the proposed research.

Note that while technical or conceptual innovation can influence the importance of the proposed research, a project that is not applying novel concepts or approaches may be of critical importance for the field. Evaluate whether the proposed work applies novel concepts, methods or technologies or uses existing concepts, methods, technologies in novel ways, to enhance the overall impact of the project. Factor 2.

Rigor and Feasibility (Approach) Evaluate the scientific quality of the proposed work. Evaluate the likelihood that compelling, reproducible findings will result (rigor) and assess whether the proposed studies can be done well and within the timeframes proposed (feasibility). Evaluate the potential to produce unbiased, reproducible, robust data.

Evaluate the rigor of experimental design and whether appropriate controls are in place. Evaluate whether the sample size is sufficient and well-justified. Assess the quality of the plans for analysis, interpretation, and reporting of results.

Evaluate whether the investigators presented adequate plans to address relevant biological variables, such as sex or age, in the design, analysis, and reporting. For applications involving human subjects or vertebrate animals, also evaluate: the rigor of the intervention or study manipulation (if applicable to the study design). whether outcome variables are justified.

whether the results will be generalizable or, in the case of a rare disease/special group, relevant to the particular subgroup. whether the sample is appropriate and sufficiently diverse to address the proposed question(s). For applications involving human subjects, including clinical trials, assess the adequacy of inclusion plans as appropriate for the scientific goals of the research.

Considerations of appropriateness may include disease/condition/behavior incidence, prevalence, or population burden, population representation, and/or current state of the science. Evaluate whether the proposed approach is sound and achievable, including plans to address problems or new challenges that emerge in the work.
