The NDAR research portal has been developed for the autism research community. The NDAR Policies, however, have multiple stakeholders with differing needs. The policy and procedures defined here address the needs of all NDAR stakeholders.
The NDAR Policy is the primary overarching policy of NDAR addressing considerations for providing data to NDAR, outlining the requirements for data submission and the protection of research subjects.
As defined by the NDAR Policy, an NDAR Data Access Committee (DAC) has been established to objectively and systematically review the requests for data submission and access to NDAR resources. Collectively, the NDAR DAC has overall responsibility for ensuring compliance with the NDAR Policy. Specifically, the NDAR DAC is responsible for the following:
The NDAR DAC consists of a minimum of 3 federal government employees appointed by the NDAR Director. Currently, the NDAR Data Access Committee comprises the following individuals with expertise in science, policy or bioinformatics resources:
NDAR is a protected resource for autism data contributed by investigators, funded by the NIH and other organizations. Contained in the NDAR Central Repository are detailed research data derived from consenting human subjects. Operational procedures have been established to ensure that the data contained in NDAR are efficiently made available to qualified researchers according to the protections defined in NDAR and other federal policies.
The standard operating procedures (SOPs) described below are to be followed by NIH, their designees, and any users of NDAR. Note that these procedures often require an investigator to upload a document into their NDAR profile and possibly associate these documents with an NDAR Collection or NDAR Study. Only the investigator and NDAR staff will have access to these documents. For any other questions or feedback, please contact ndarhelp@mail.nih.gov.
NDAR is a restricted access portal to research data relevant to autism. An NDAR account is required to submit or access autism-related data. Investigators and data managers at research sites are invited to request an account. To provide maximum protection for the confidentiality of research participants whose data is stored in NDAR, professional credentials are verified by NDAR Staff during the account request process.
Procedure
This procedure provides process steps for account request initiation, authorization, and validation. The entire procedure typically requires 1-3 business days.
Account Request Initiation
Account Request Review and Authorization
Account Validation
To request additional privileges for your NDAR account, please refer to the following procedures:
To submit data to the NDAR research portal, an investigator is required to complete an NDAR Data Submission Agreement. With an approved submission request, an investigator can submit descriptive data, experimental data, and a variety of supporting documentation associated with a research study to an NDAR Collection — a virtual container for storing research data. To create an NDAR Collection, an investigator must have at least one current Data Submission Agreement uploaded to the NDAR portal.
The Data Submission Agreement must be signed by two parties:
The person responsible for collecting the data is typically the Principal Investigator. Alternatively, it could be a co-Investigator who is responsible for data coordination for the study. The person who signs the form will create the NDAR Collection.
The NIH-recognized business official is the same person that signs off on grant applications at the research institution.
Procedure
This procedure provides process steps for data submission privilege request initiation, review and approval. The entire procedure typically requires 10 business days.
Data Submission Privilege Request Initiation
Data Submission Privilege Request Review and Approval
As a Federal Information System, NDAR will follow NIH Security Certification and Accreditation as defined at http://ocio.nih.gov/nihsecurity/NIH_System_CnA.htm. NDAR is rated at a Security Objective of Confidentiality and a Potential Impact Level of Moderate. This level of security is defined by NIST publication 800-18 Guide for Developing Security Plans for Federal Information Systems:
"The unauthorized disclosure of information could be expected to have a serious adverse effect on organizational operations, organizational assets, or individuals."
The NDAR Data Access Committee has authorized the NIH Center for Information Technology (CIT) to oversee its certification and accreditation utilizing objective third parties to perform NDAR's security certification and accreditation.
The NDAR research portal will provide investigators with a single point of access to multiple autism-relevant data sources (e.g., AGRE, IAN, NIMH Genomics Repository) in addition to the shared data stored in the NDAR Central Repository.
For permission to query and access shared data stored in the NDAR Central Repository, an investigator is required to complete the following. Please refer to the Data Access Document Completion Instructions for more information.
Both forms must be signed by two parties:
For permission to query and access shared data stored in data sources that are federated with NDAR, an investigator will be expected to complete access agreements specific to these data sources in addition to the SF-424(R&R) and Data Use Certification. Procedures for requesting access to specific federated data sources will be made available as these data sources come online. Until then, contact ndarhelp@mail.nih.gov with any questions.
For permission to query and access data stored in the NDAR Central Repository that have not been shared, please read SOP-09 Request Ongoing Study prior to performing these procedures.
Procedure
This procedure provides process steps for data access permission request initiation, review and approval. The entire procedure typically requires 10 business days.
Data Access Permission Request Initiation
Data Access Permission Request Review and Approval
The quality of data within NDAR is crucial for ensuring its usefulness and reliability for research. Therefore, the NIH has implemented a multi-tiered quality control procedure for data contributed to NDAR.
Procedure 1: Validation of Data Elements Made Available by NDAR
Prior to a Data Dictionary release or the establishment of a federated data resource, NDAR Staff will certify that the fields defined do not include any information that can be reasonably used to identify a research subject, their specific geography or individuals associated with the research. Although not applicable to NDAR, the HIPAA Limited Dataset definition will be used as the basis for this certification. Specifically, NDAR staff will ensure that the following direct identifiers of the research subject or of relatives, employers, or household members associated with the research subject are removed:
Any potential discrepancies to this privacy rule (e.g., genomics data or images that could be transformed) will be documented and approved/denied by the NDAR Data Access Committee (DAC).
Procedure 2: Sharing of an NDAR Study or NDAR Collection
An NDAR Collection is a virtual container for research datasets contributed to the NDAR Central Repository or made available through federation. An NDAR Study contains references to specific participants either within the NDAR Central Repository or a federated data resource. Both NDAR Collections and NDAR Studies allow for supporting documentation to be uploaded and shared.
Investigators may create NDAR Collections or NDAR Studies many months prior to submitting data to them. As containers empty of research data, NDAR Collections and NDAR Studies contain only general information such as the project title, contributing investigators and funding source. These containers may be shared either to specific individuals through NDAR's Ongoing Study capability or broadly with other researchers. The decision to share an NDAR Collection or NDAR Study is based solely upon the discretion of the owner of the NDAR Collection or NDAR Study. No additional review is necessary.
Sharing an NDAR Collection or NDAR Study only makes general information available to others. Documentation contained in the NDAR Collection or NDAR Study or data contained in the NDAR Collection must follow specific data sharing procedures, defined below.
Procedure 3: Validation of Documents within an NDAR Collection or NDAR Study
For documentation uploaded to NDAR, the following procedure will be followed.
Procedure 4: Validation and Sharing of an NDAR Dataset
Datasets contributed to the NDAR Central Repository are shared with those that have appropriate access. The same process is followed for data shared broadly or data shared through NDAR's Ongoing Study capability.
The NDAR portal has been designed to federate with external data sources, providing investigators with a single point of access to multiple autism-relevant data sources (e.g., AGRE, IAN, NIMH Genomics Repository) in addition to the shared data stored in the NDAR Central Repository.
The following procedure is required to establish a federated resource.
Procedure
These procedures will be developed in support of the NDAR Data Dictionary, when it becomes available. Contact ndarhelp@mail.nih.gov to help lead the autism research community in defining the NDAR Data Dictionary.
In the NDAR Central Repository, research data associated with an individual participant are linked by means of a Global Unique Identifier (GUID) that protects personally identifiable information (PII) about the participant. GUIDs allow investigators to track participants longitudinally, across multiple research sites and across multiple studies.
The GUID is generated using a free software application installed at the research site. The software uses four items found on a typical birth certificate:
If all four items were not collected from participants, the software can be used to generate pseudo-GUIDs, which can be converted to valid GUIDs at a later date.
Participant GUIDs or pseudo-GUIDs are required to submit data to NDAR.
Procedure
This procedure provides process steps for GUID client request initiation, review, approval and verification. The entire procedure typically requires 4-5 business days.
GUID Client Request Initiation
GUID Client Request Review and Approval
GUID Client Verification
NDAR's Ongoing Study capability allows investigators to work collaboratively on research studies in progress; sharing data, tools, and standards through the NDAR portal before they are shared with the rest of the ASD community.
To request this capability, an investigator is required to review the Ongoing Study Policy Addendum to the NDAR Policy and communicate with potential collaborators to develop a request for an ongoing study. An Ongoing Study Request Template is provided, and includes:
The lead investigator designated as primary point of contact is required to have an NDAR account with at least one current Data Submission Agreement uploaded. Co-investigators are required to have an NDAR account. Please refer to SOP-01 NDAR Account Request and SOP-02 Data Submission Privilege Request for these procedures.
Procedure
This procedure provides process steps for ongoing study request initiation, review and approval. The entire procedure typically requires 10 business days.
Ongoing Study Request Initiation
Lead investigators:
Co-investigators:
Ongoing Study Request Review and Approval
Ongoing Study Participation
Lead investigators:
As the owner of the NDAR Collection/Study, the lead investigator will then be free to assign particular individuals to the NDAR Collection or NDAR Study to allow them access to data and/or documents contained therein. Please refer to the procedures defined in SOP-05 Quality Assurance and Quality Control prior to sharing.
This request applies only to data contained in the NDAR Central Repository.
After an investigator has submitted data to the NDAR Central Repository, the NDAR policy defines a timeframe in which QA/QC activities are to be performed prior to data being made available for sharing. Investigators, please refer to the data-sharing policy associated with your specific research study to determine the length of time between data submission and data sharing.
The investigator may request an extension to this timeframe if, in the interest of science, there are reasons for which the release of data would be considered premature. Extensions will not be granted for the singular purpose of delaying QA/QC activities.
To request this extension, an investigator is required to develop a brief, written request to include:
For an extension supporting a longitudinal outcome, identify which time points may be provided (e.g., baseline) and which time points should be withheld.
Procedure
This procedure provides process steps for time extension request initiation, review and approval. The entire procedure typically requires 10 business days.
Time Extension Request Initiation
Time Extension Request Review and Approval
Over the course of research, circumstances may arise that necessitate a change in the data sharing terms associated with NIH funded research. In anticipation of this need, the following procedure has been developed.
Procedure
NDAR Staff
NDAR technical and operational staff must have access to NDAR resources, including the ability to query and review research data within NDAR. The NDAR Director is responsible for granting individual access to those administering NDAR. The NDAR Director may choose to delegate the responsibility of granting access to other NDAR Staff.
Extramural Program Staff
Extramural program staff, or their designees, must be allowed to query NDAR data. Requests for such access will be approved by the NDAR Data Access Committee. The procedure for requesting such access will follow procedure SOP-04 Data Access Permission Request but require a document specifying the reason for the request in lieu of forms SF-424(R&R) and the NDAR Data Use Certification.
Beginning in fiscal year 2012, all NIH funded human subject research data related to autism is expected to be shared through the National Database for Autism Research (NDAR). For new projects, the data sharing terms will be included in the Notice of Grant Award (NGA) which will also include expected timelines for data submission. For projects enrolling new research subjects and collecting new data on those subjects, both descriptive and experimental data are expected to be deposited into NDAR. When experimental results are obtained from a dataset originating from an NDAR federated source (e.g. ATP, AGRE), only the newly derived experimental data are expected to be submitted to NDAR in an effort to avoid duplication. While most data are expected to be submitted directly into NDAR, there may be valid scientific and/or operational reasons for submitting data, either descriptive and/or experimental, into another repository and not NDAR. However, to ensure that data remains available to the research community, only repositories that are federated with NDAR, make the data generally available to the autism research community, and have a memo of understanding (MOU) in place with NDAR ensuring such data deposited remain available to the community in perpetuity, will be considered.
The following procedure should be followed for such cases.
Procedure
Investigators who wish to use another repository for data sharing should first consult with their Program Officer. If the Program Officer believes that it is appropriate for the investigator to submit to a repository other than NDAR, then the investigator should provide the following information to ndarhelp@mail.nih.gov:
NDAR Staff will provide the request to submit and share data through a federated repository and any related information to the NDAR Data Access Committee (DAC) for a decision. The NDAR DAC meets twice a month to review these requests. NDAR Staff may contact investigators and/or the Program Officer for additional information if required. The NDAR DAC reviews the request and makes a decision based on the information provided in the request. Final approval of the request to submit to another repository instead of NDAR is contingent upon approval from both the Program Officer and the DAC. Once approved, NDAR Staff will send an e-mail message to the lead investigator with the decision. The entire procedure typically requires 10 business days.
The Policies and Procedures listed here are reviewed and approved by the NDAR Leadership Team periodically, at a minimum of once per year.
