NDAR provides a single access to de-identified autism research data. For permission to download data, you will need an NDAR account with approved access to NDAR or a connected repository (AGRE, IAN, or the ATP). For NDAR access, you need to be a research investigator sponsored by an NIH recognized institution with federal wide assurance. See Request Access for more information.

Request Access to Shared Data

Summary information on the data shared in NDA is available on the NDA homepage without the need for an NDA account. You can also build queries and view summary information on data without an account. To request access to detailed human subjects data, you must be sponsored by an NIH recognized institution with a Federalwide Assurance and have a research related need to access NDA data. NDA federated repositories have their own access requirements.

If you meet the above criteria, you can request access by completing a Data Use Certification, and signing it, or having it signed by the investigator if this is not you, and an institutional official with signature authority. If you do not know your institution's signing official, contact us at The NDA Help Desk. Additional research staff from the same institution may be added to the Data Use Certification by completing the Senior/Key Person Profile (Collaborating Investigator) section. There is no limit to the number of additional staff members who can be added to a data access request so only one request is needed for your entire lab.

 

Create an account here and upload the scanned Data Use Certification to your profile, which you can access in the upper-right corner of NDA when logged in, or simply email it to NDAHelp@mail.nih.gov.

 

Once completed, the request is reviewed by the Data Access Committee (DAC) established to oversee access to the NDA shared data. Refer to SOP-04 Data Access Permission Request for the entire procedure.

Those approved will have access to NDA for one year after which you will need to reapply. Those publishing are required to acknowledge NDA as defined in the Data Use Certification. Additionally, the sharing of an NDA Study is strongly encouraged to provide proper attribution to those who initially collected the data.
