In addition to our Q&A, we've made it easier to find answers about Submission, QA, and Closeout!
The new fact sheets are designed for at-a-glance help to answer the most asked questions about submitting data and managing your NDA Collection throughout the course of your grant.

Feel free to share this information with the appropriate staff on your project.
As always, you can email the NDA Help Desk with any questions! NDA Help Desk hours are weekdays from 8:30am-5:30pm ET.
NDA recently learned there is a typo in the Common Data Element (CDE) cde_dsm5crossyouth01.
The dsm_cross_ch25 has an incorrect question as referenced in APA-DSM5TR-Level1MeasureChildAge11To17. A new element, dsm_cross_ch25a, has been created to correct the wording.
- The previous question reads (dsm_cross_ch25): Have you thought about killing yourself or committing suicide?
- This has been changed from a “required” element to a “recommended” element.
- The updated and corrected question reads (dsm_cross_ch25a): Have you ever tried to kill yourself?
- This question is now a “required” element.
Please note: If you are collecting data for this element from this point forward, please use the corrected question in dsm_cross_ch25a. You will be permitted to submit data to the previous question if you have already started data collection using it.
Improved Security for the GUID Tool
NDA updated the login process to the NDA GUID Tool using two-factor authentication for added security. Previously, you were required to log into the GUID Tool using your NDA username and password. Now, the GUID Tool requires the same two-factor authentication as the NDA website.
After launching the NDA GUID Tool and accepting the terms and conditions, you will be presented with a RAS login screen, as shown below.
To log in, click the 'Sign in with RAS' link, and a separate browser window will open with the RAS login page. On successful authentication, you will be directed back to the GUID Tool Dashboard screen and can proceed with using the tool as normal.
Data Release for the Osteoarthritis Initiative (OAI)
NDA has new OAI data! Nearly 5,000 clinical assessments and neurosignal recordings data from the Osteoarthritis Initiative (OAI) have been shared and are now available in NDA.
OAI is a multicenter, longitudinal, prospective observational study of knee osteoarthritis (OA) that started in March 2004. The OAI data resource was transferred from the UCSF Data Coordinating Center to the NDA hub in 2017. Recently, there has been a significant update from NDA that has streamlined the setup process of populating Data Expected Lists. This enhanced method accelerates and improves efficiency in mapping of Data Structures to users’ Data Expected Lists.
The OAI cohort of 4,796 participants is 58% female and ranged in age from 45-79 at time of recruitment. Retention remained high throughout the study duration. Some participants (about 7%) from the original cohort with 4 years of follow up did not continue for the additional five years of more limited follow up. The rate of no-contact stabilized in the 15-18% range. The entire OAI cohort has completed:
- Baseline, 12-month, 24-month, 36-month, and 48-month visits in clinic with biospecimen collection and imaging
- 60-month and 84-month visits via mailed questionnaires and telephone interviews
- 72-month visit in clinic with biospecimen collection and imaging
- 96-month visit in clinic with imaging
The above visits were completed as of January 1, 2015. The follow up continues for subsets of the cohort. There are biological specimens available for baseline, 12-month, 24-month, 36-month, 48-month and the 72-month visits. A subset of participants in the progression cohort were also seen at 18 months (n=288) or 30 months (n=494) for knee MRI, blood collection, exam, and questionnaire data to allow for analysis of change over shorter intervals. To learn more about the history of the OAI, please visit the NIAMS Archive.
All data access information is documented on the NDA OAI website. This website contains the permanent archive of the clinical data, patient reported outcomes, biospecimen analyses, quantitative image analyses, radiographs (X-Rays) and magnetic resonance images (MRIs) acquired during this study. Biospecimens have been collected from OAI study participants, including serum, plasma, urine, and DNA. We encourage interested investigators to apply for use of these limited resources. To learn more about the OAI Biospecimens Access Policy and Procedures, please see the Osteoarthritis Initiative Biospecimen Access Policy Statement. To learn more about how to apply for OAI biospecimens, please review the Osteoarthritis Initiative Application Guide for Biospecimen Studies. In addition, genomic data from the ancillary Genetic Components of Knee Osteoarthritis (GeCKO) study, a genome-wide association study on the entire OAI cohort is available at the NCBI dbGaP website. Investigators can use this unique repository to track the natural history of knee OA across the complete spectrum of disease.
NDA Website Enhancements
Modernized Website Layout
NDA has updated its pages to share the same look and feel, providing a more consistent user experience!
- The menu structure is now the same for all pages within the NDA site. Other sites under the NDA domain (e.g., ABCD, OAI, etc.) will continue to have context-dependent menus, which use the same look and feel.
- General fields on the page (e.g., tables, dialogs, buttons, etc.) have been updated for consistency.
- On every page, if you're not logged in, you will see a "Login" button. If you are logged in, you will see a "My Account" button. Many of the menu options that were spread across the previous menu have been consolidated here. This is also where you will see any role-based menu items.
Validation Tool Improvements
The HTML Validation Tool now loads Submissions with QA errors significantly faster! New cosmetic changes make the purpose of the buttons on the pages clearer.
Updated Program Officers and Grants Management Officials (PGMO) Site
NDA changed accessibility to the PGMO site improving visibility and security. The new "PGMO" link is located at the top of every page when authorized users are logged into NDA. Only NDA users with the following roles will see the PGMO link:
- NDA Admin or Staff
- Program Analyst
- Program Official
- Grants Management Offical
- Grants Specialist

Contacting the NDA Help Desk
Need help, no problem! The most efficient way to get assistance or information from NDA is to email the NDA Help Desk and include as much information as possible.
Here are some helpful tips to resolve common issues and expedite your request:
- Logging in to your NDA account:
- If you need to create an NDA account, click here.
- If you are not sure if you already have an NDA account, email the NDA Help Desk for confirmation to prevent creating multiple accounts, which may cause issues later.
- Questions about your specific NDA Collection:
- Please include your NDA Collection ID (ex. C1234) in your Help Desk request. This will allow NDA Help Desk agents to provide quicker service.
- If you are unsure of your NDA Collection ID, you can provide your grant number.
- Having technical issues?
- Please provide screenshots if possible.
- Provide as many details as you can (i.e., what browser you are using, what you were doing when it happened, etc.).
- If you are receiving an error message, provide the exact error message that appears.
- Please be sure you are logging in with your account and not another user's account.

Mandatory Common Data Elements (CDEs) for HIV-related Grants
For NIMH HIV-related research that involves human research participants, three data structures are automatically added to the 'Mandatory Data Structures' section of the Data Expected List:
Select the structure(s) most appropriate for your research. If your research does not require all three, just ignore the ones you do not need. There is no need to delete the extra structures from your NDA Collection. You can adjust the Targeted Enrollment column in the Data Expected tab to “0” for those unnecessary structures. At least one of the three data structures must have a non-zero value.
