When are survey data documents (PDFs) updated?

The release of survey documentation is timed to match the release cadence of new dataset versions. As participant data from additional surveys is added to the dataset, the survey documentation will be updated to correspond. You can search for specific survey questions and/or answers along with their corresponding OMOP concept codes by accessing our survey codebooks or by browsing and/or downloading all All of Us concepts via ATHENA, the Observational Medical Outcomes Partnership (OMOP) community's searchable database of standardized vocabularies it supports. To browse All of Us PPI concepts in ATHENA, select "Vocabulary" in the left-side navigation bar and scroll to "PPI."
