Comparison to the International Personality Item Pool (IPIP)

Like IPIP, we support research by making it free to include our materials in studies.

Unlike IPIP, we protect scoring keys so that material remains useful in high-stakes testing.

Options for including our materials in your studies

  1. Add materials into your chosen research platform (e.g., Qualtrics, SurveyMonkey).
  2. Invite participants to complete materials on our testing platform. All device types are supported.
  3. Use our API to integrate the survey into your own testing platform.
