For Researchers

• Accessing VETSA Data

  Deidentified VETSA Wave 1, 2 and 3 data are now accessible through the VETSA PIs and will soon be available via the ICPSR website. VETSA 4 data will be available in late 2024.
  
  • The Basic Process:
    There are 4 simple steps for qualified researchers interested in using VETSA data:
    1. Take a look at the list showing many of the VETSA measures.
    2. Fill out and submit a Data Request Form; we will send you a complete data dictionary.
    3. If the request is approved, you will be asked to fill out and submit a Data Use Agreement (DUA).
    4. Upon receipt of the signed DUA, we will provide the relevant data.
