Manuscript Preparation

Researchers who share data through NDA, or who conduct a secondary analysis on any data shared through NDA, are expected as part of the Terms of Use to report their results using the NDA Study feature. An NDA Study links a finding, data release, or publication directly to the underlying subject-level records for the outcome measures defined. Automatically, the NDA Study provides attribution (i.e. credit) for those that contributed the data. Each NDA Study is also issued a Digital Object Identifier (DOI), which is expected to be referenced in the publication as a persistent link to the supporting dataset. Read on to learn more about how the NDA Study must be used to cite data and provide acknowledgement of its original collectors when used for secondary analyses, and how to create one while preparing to publish a manuscript.


NDA Study Acknowledgements

The NDA Study provides appropriate attribution to those who have collected, analyzed, and/or published on data. The Data Use Certification (DUC), which must be completed and its terms agreed to by qualified researchers seeking to access shared data, includes an expectation that appropriate attribution be provided to those who have made a substantial contribution to the NDA by submitting data. The NDA Study automatically provides this attribution.  Therefore, when publishing on their own or others data, researchers are expected to create and share an NDA Study and include the following acknowledgement in any oral or written presentation, disclosure, or publication, which includes a disclaimer of NIH endorsement, as appropriate:

 Data used in the preparation of this article/presentation/etc. reside in the NIH-supported NIMH Data Archive in [NIMH Data Archive Collection ID(s) or Study DOI]. 

and can thus link this data to a publication. The NDA Study itself includes an "attribution report", calling out the grants and Principal Investigators responsible for the original collection of the underlying data and linking to the original datasets in NDA. In order to appropriately include such acknowledgement and obtain a usable DOI that can be included in the original publication, the NDA Study must be created, but not necessarily finalized, before the publication is released. 


NDA Study Creation

If you are preparing a manuscript, have recently published or at the end of grant award, it is likely time for you to create an NDA Study. A brief tutorial on how to create an NDA Study can be found below, along with an outline of the basic steps below that:


How to Create an NDA Study


  1. The NDA Study is created initially by clicking an "Add New Study" on the Data From Papers page.
  2. In the empty NDA Study, enter in all applicable information in the General tab. Once you've completed it sufficiently, "Save" it using the button at the bottom.
  3. In the Cohorts tab of the Study, create one or more Cohorts, filling out required information to describe them. "Save" the page after adding each Cohort. You should now have one or more empty Cohorts with descriptive information.
  4. Complete the appropriate information to provide queryable metadata on your NDA Study in the rest of the tabs and "Save"
  5. Leaving your incomplete Study, proceed to any of the NDA Query tools, and build a package of the subjects whose data are used in this manuscript. The easiset way to do this is to enter their Global Unique IDs (GUIDs) into the Query by GUID tool.
  6. Proceed to the packaging step through your Filter Cart but assign these subjects to the appropriate Cohort using the options available instead of packaging them for download.
  7. Once this is completed for all Cohorts, return to the Cohorts tab and add measures, designating them as primary or secondary outcome measures.
  8. Once all data are specified and all tabs completed, you can "Save" the NDA Study and share it.

If your manuscript is not ready to publish and the data not ready to share, you can leave an NDA Study incomplete at any step in the process, being sure to save your progress. Even an empty shell of an NDA Study can be assigned a Digital Object Identifier (DOI).

The DOI is a persistent link to the location of the dataset, which can be used as a way to cite it in your manuscript as defined in the Acknowledgement section of your Data Submission Agreement or Data Use Certification. In order to properly include this citation in the manuscript, you'll need to prepare ahead of time by creating an NDA Study and getting your DOI generated. In other words, the broad steps will be;

  1. Begin preparing your manuscript
  2. Visit the NDA website and create at minimum a placeholder or shell (if possible you could complete its creation) NDA Study
  3. Generate a DOI in the NDA Study
  4. Add the DOI to your manuscript as defined in the Acknowledgement section of your agreement
  5. When the paper is ready to be published, complete the NDA Study if needed, and share it when appropriate.

Data are shared at a granular level (e.g. specific outcome measures by subject/timepoint) when an NDA Study is created, allowing other unpublished data that is not scheduled for sharing to remain private.  A DOI is issued for each NDA Study and authors are expected to reference the location of data in the publication using the DOI.  To do this, authors are expected to contact the NDA Help Desk when a manuscript is submitted for review, so that the NDA Study and the DOI can be issued and included in the actual publication.  A DOI for the underlying data may increase the visibility of your work.

There is another way to create an NDA Study if your publication has already been released and cites a grant number supporting the project submitting data to your NDA Collection. Each Collection has a Publications tab, which lists publications in PubMed that reference the grant number associated with that Collection. This tab is populated automatically, and you can view the tab to mark publications as relevant or not relevant to the data that has been submitted to your Collection. If a publication is relevant, you can click Create Study to begin the process from this tab. This will take you to the unsaved General tab of your new Study, pre-populated with all of the required information, pulled directly from PubMed. Please note manuscripts should have an associated DOI and NDA Study prior to publication, so this feature should only be used as a convenient way to report results retrospecitvely or to correct a mistake and a publication that may have been missed.

Data that are part of your "Analyzed" dataset as defined in the Data Sharing Regimen will be shared 2 years after your project end date, or when published - whichever is earliest.
