Single SurveyPID 4
Survey Distribution Tools
Public Survey Link Participant List Survey Invitation Log
The Participant List option allows you to send a customized email to anyone in your list and track who responds to your survey. It is also possible to identify an individual's survey answers, if desired, by providing an Identifier for each participant (this feature must first be enabled by clicking the 'Enable' button in the table below). Note: All survey responses collected are considered anonymous unless you 1) are using Participant Identifiers or 2) have enabled the designated email field for invitations. More details

Disabled:
Participant Identifiers are disabled and thus cannot be used in this project. Only a REDCap administrator can enable Participant Identifiers once the project is in production status.
Cannot modify:
The participant's identifier cannot be added after the record has been created if the identifier was originally blank beforehand. This is to prevent users from adding an identifier after the fact and thus incidentally turning an anonymous response into an identifiable response.
Cannot add or modify identifier:
A participant identifier can only be *added* before the record has been created. It can be *modified* if the identifier existed before the record was created; however, the only place it can be modified is on Participant List for an Initial Survey (i.e. the first instrument).
Cannot modify email address here:
A participant's email address cannot be modified here but *can* be modified on the Participant List for an Initial Survey (i.e. the first instrument). Alternatively, if you are utilizing a 'designated email field', then you may modify the email address on the data collection instrument where the 'designated email field' is located.
Cannot modify phone number here:
A participant's phone number cannot be modified here but *can* be modified on the Participant List for an Initial Survey (i.e. the first instrument). Alternatively, if you are utilizing a 'designated phone field', then you may modify the phone number on the data collection instrument where the 'designated phone field' is located.
Cannot modify email address here:
The participant's email address cannot be modified here because it originates from the 'designated email field'. However, you can modify the email address on the data collection instrument where the 'designated email field' is located.
Cannot modify phone number here:
The participant's phone number cannot be modified here because it originates from the 'designated phone field'. However, you can modify the phone number on the data collection instrument where the 'designated phone field' is located.
Response cannot be viewed:
When clicking the 'Responded' icon, you may only view responses that have a Participant Identifier defined. Thus you will not be able to view this participant's response by clicking this icon. This is done in order to preserve this response as anonymous.
Among the participants selected, 0 participants have survey invitations that are already scheduled to be sent. These participants will have their survey invitations rescheduled for the new time you specified. If you do not wish to reschedule them but instead wish to keep the current scheduled time, then click the Cancel button below and deselect them in the list.
