Distribution settings

The distribution settings screen provides settings for activating and deactivating the study, managing participant access and egress, and managing collaborators on shared studies. Multiple participant sources can be set which provides great flexibility in participant recruitment.

Activate and deactivate study

Studies can be activated and deactivated by toggling the Activate study / Deactivate study button located on the right hand side of the study tab bar.


Participant settings (participants tab)

The participant settings screen allows customization of how participants access the study, where participants are redirected to upon completion of the study, including various security related settings (e.g. bot prevention using reCAPTCHA). When creating a new study, a default Public participant source is automatically added to the study (Figure 1). This participant source can be edited or deleted, and/or be added to with additional participant sources.

Adding a participant source

New participant sources can be added to the study by clicking New (Figure 1). Choose from any of the available participant sources (Figure 2).

Note: multiple participant sources can be used within a study, however only one Public source can be used in a study at a time.

Each participant source has its own study link so be sure to use the right one for each source when advertising your study or when changing your settings in your management service.

Participant sources include:

  • Public: Anyone can enter the study.
  • Public + reCAPTCHA: Anyone who passes the reCAPTCHA (human verification check) can enter the study. Participants need to perform a quick task (approx 5 to 10 seconds duration) before access to the study is granted.
  • Public + password: Anyone with the correct password can enter the study.
  • Public + password + reCAPTCHA: Anyone with the correct password who passes the reCAPTCHA (human verification check) can enter the study. Participants need to perform a quick task (approx 5 to 10 seconds duration) before access to the study is granted.
  • Sona Systems: Sona Systems is a participant management service typically provided by universities.
  • Positly: Positly is a participant recruitment and management service.
  • Prolific: Prolific is a participant recruitment and management service.

Author's note: reCAPTCHA is a simple cognitive challenge (courtesy of Google). A successfully completed task provides a very strong indicator that the participant is human.

Editing a participant source

Participant sources can be edited by clicking on the source to reveal the participant source list (Figure 2). The completion link can be edited, and on applicable sources, the password can also be changed.

Deleting a participant source

Sources can be removed by clicking Delete on the relevant source.

Completion links

Participants will be redirected to the link supplied (Figure 1) upon completion of the study. This functionality is particularly useful for sending participants back to where they were directed to the study, or to send them on to the next step in whatever workflow is being executed. This feature is heavily used by participant management services and crowdsourcing services. If left blank, participants will be redirected to the Psychstudio home page.


Collaborator settings (collaborators tab)

Studies can be shared with multiple users within Psychstudio allowing them to view and edit the study. Study owners (either the original creator or someone who has since been granted ownership) can invite others to collaborate on the study, invite others to take ownership of the study, and remove collaborators from the study. Study collaborators (those who do not own the study but do have collaborator access) can remove themselves from collaborators but are not permitted to invite others to collaborate or delete the study.

Inviting new collaborators (study owner only)

New collaborators can be invited to share your study by clicking Invite new collaborator (Figure 2). You will be presented with a form that requires the email address of your invitee and optional message. Invites are sent by email.

Transferring study ownership (study owner only)

Study ownership can be transferred to another user by clicking Transfer ownership (Figure 2). You will be presented with a form that requires the email address of your invitee and optional message. Invites are sent by email.

Removing collaborators (study owner only)

Collaborators can be removed from your study by selecting the collaborator(s) using the checkbox next to their name(s) and clicking Remove collaborators (Figure 2). Note: owners cannot remove themselves.

Removing yourself from study collaboration (study non-owners only)

Collaborators can remove themselves from a study by clicking Leave collaborators (Figure 3).
