NIMH Data Archive (NDA) Data Dictionary

This page displays a list of all the structures currently supported in the NIMH Data Archive (NDA) Data Dictionary. Each structure represents a standardized definition of a measure that has been defined by researchers. On this list you can view:

  • Title: The name of the measure. This list is sorted alphabetically by title by default
  • Short Name: The NDA abbreviated ID for the structure
  • Shared Subjects: The number of unique subjects with shared data in this structure
  • Sources: Which NDA database(s) or federated systems include projects that have used this structure
  • Categories: The type of measure, relevant mental health issue, or other way of categorizing the structure
  • Submission: Some structures are obsolete, superseded by newer structures, or were created to support legacy projects. This column will display "Allowed" or "No" to indicate whether or not submissions of new data are currently accepted in this structure.

You can use the Search bar to filter the displayed structures based on category and title, or use the arrows in the header row to sort the current display based on that column. Once you’ve located a structure of interest, click on the title to enter the individual structure page.

You can use the check-boxes on the left to make selections and "Download" to add all data in those structures to your download cart. Please email the The NDA Help Desk with any questions.
