Accessing VETSA Data
De-identified VETSA Wave 1, 2 and 3 data is publically available through the National Archive for Computerized Data on Aging (NACDA): https://www.icpsr.umich.edu/web/ICPSR/studies/38836 

De-identified VETSA Wave 4 data is in preparation and will eventually be publically available. Please let VETSA PIs know if you are interested in using Wave 4 data for your project. 

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 (can you also use the variable search function in NACDA; and look at relevant codebooks/documentation
2. If requesting data not on NACDA, fill out and submit a Data Request Form
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.
