REDCap has the ability to repeat a data collection instrument or an entire event of instruments an unlimited number of times without having to specify the amount needed.
|
The following are instructions how to do this:
Go to "Project Setup"
Scroll to the "Enable optional modules and customizations" section and click on "Enable" next to "Repeatable instruments and events" (circled in red in image below)
Select which events or forms you want repeated. Do this by clicking on the "-- not repeating --" box (circled in red below) and selecting "Repeat Entire Event (repeat all instruments together)" or "Repeat Instruments (repeat independently of each other)"
If repeating instruments (and not full event), select which instruments you would like repeated in the "Instrument name" column. You can also label the repeating instruments by typing in a variable name of the question you would like them to be labeled by in the blank text box (located to the right side)
(For surveys) If one wishes to allow survey participants to fill out a survey for an event more than once, they must enable an optional setting in the Survey Settings page. This is done by doing the following:
Go to the "Online Designer", and click on "Survey settings" button that's next to the survey you want to repeat.
Scroll to the bottom and select "(Optional) Allow respondents to repeat the survey" (circled in red in image below)
Set the custom text or the button and select the location of the button. The options and a description are the following:
Before survey is completed, next to Submit button – At the bottom of the survey will be a button to "Take the survey again" (as shown in image below). Once "Submit" is selected, participants will not be able to return and make a new entry on this survey for this event again. This is can be very useful when entering medications or something similar to it.
After survey is completed, below Survey Completion Text – When survey is submitted, will go to a page similar to the one shown in image below where participant has the choice to take survey again. This setting can also be used to resend the survey for the same event, new entry (mainly done through the participant list).
Repeat instruments is now set up. When you open a record, the "Data Collection Instrument" table will appear with the different colored dots to indicate if the instrument has been filled out or not; a blue dot indicates different statuses for separate entries. Repeating Instrument tables will be below the "Data collection Instrument" table and contain repeated instruments and the entries made (as shown in image below). Can add a new entry on these by clicking "+ Add new". Can also add a new entry by clicking on the + sign in the "Data Collection Instrument" table
