# About Study Participants

Source: https://sites.veevavault.help/gr/sitevault/studies/about-participants/

In SiteVault, a Participant is a patient who is being screened for or participating in a study. All Participants are patients, but not all patients are necessarily Participants.

## Participant Lifecycle

The Participant lifecycle enables you to manage and track a participant’s status throughout the study. When you first create the Participant record, the initial status is **Candidate**.

To change a Participant status, select the appropriate state from the button in the **Status** column.

The figure below illustrates an express version of the sequence of states that are available for Participant records in SiteVault. Click **View Full Lifecycle** to view the full sequence of states that are available for participant records in SiteVault.
