You can create surveys as you would in Survey Monkey and data forms, e.g. Case Report Forms (CRF); or a combination of both.

There are three project types available in REDCap:

  1. Data collection performed only by study team using Data entry forms

  2. Data collection performed only by subjects / study participants using Surveys

  3. Screening phase before enrolling subjects using Survey + Data entry forms

There are two collection formats available for data entry forms:

  1. Classic: one record per patient

  2. Longitudinal: one record per patient per event, with the possibility of defining multiple arms

Data Collection Forms:

  • Must be filled out by a user who logs into REDCap.

  • Simply add the users to your project and have them click on “Add/Edit Records”

  • Advantages:

    • Users entering data have the ability to see all data they’ve previously entered, edit previous responses, or check for updates.

    • Users not only have access to data entry, but all other REDCap features (reports/exports, Training Videos, File Repository, Data Quality checks, etc.).

    • Easier to troubleshoot errors because of the log that accompanies data entry.

    • All entries are logged with a timestamp. REDCap tracks who entered data, any changes with old and new values, the IP address where it was entered, the date and time, etc. NOTE: This timestamp is not included in reports or exports though.

    • User have the ability to give a form a status, marking it as “complete” or “incomplete” depending on what is most useful for workflow.

Surveys:

  • Intended to be filled out participants (non-REDCap users)

  • No login required.

  • Responses are anonymous unless survey invitations are used and combined with a Participant Identifier (different from marking a field as an identifier in the Online Designer).

  • Web interface has a sleeker design and can be customized with Logos and instructions.

  • Advantages

    • Survey responses are anonymous (can also be a disadvantage).

    • All completed surveys have a date and timestamp that can be included in reports and exports.

    • Easier to enter responses from a smartphone or tablet.

    • No need for logging in or adding users.
