Great presentation! But, could you please answer to the following: the same way as one can create unlimited repeated forms using the basic (non-longitudinal) method, is it also possible to create unlimited repeated follow-up visits (events) using the longitudinal method instead of defining a specific set of events? Thank you.
Is longitudinal function can only be used with time event? I want to create a data for different episode of infection. Can I use longitudinal function for episode 1, episode 2, episode 3 etc instead of using repeating form? Thanks in advance !
thank you for sharing this. How do I decide when to use a repeating instrument and a longitudinal survey. I have a baseline form and two additional forms that I wish to administer repeatedly: one daily for 1 week and the other weekly for 13 weeks. Sources hint repeated instruments are ideal when the collection count is not deterministic.
Great question. Repeating is best if you don't know how many times you will be collecting the data. But I would typically recommend longitudinal in this case since you know the specific time points and they seem to be consistent, you can designate the time points just as you described above, Day 1, Day 2 . . . Day 7, Week 2, week 3 ... week 13. Hope this helps!
@@researchinformatics1635 thanks for this timely response. I did implement this just using the option you suggested. Now on longitudinal studies, how would you prevent field workers from clicking follow up event or timepoint 3 before clicking 2, and also prevent clicking any follow up event if the consent status on the baseline form is no.
@@francisopiyo2332 I don't think you can stop users from adding new instances of a repeated form or event even when the instance that preceded it was empty. However, if you can prevent that from happening if the forms were filled out as a survey instead. The problem with this approach is that it carries its own problems and limitations.
Say I am using a repeat instrument over the span of several weeks. Is there any way to have the survey questions randomize so that they appear in different orders each week?
Excellent question, one we've gotten a few times. the order of questions cannot be randomized in REDCap, only the question answers using an action tag. You can check with your local redcap admin if there is any external module that might help with that functionality.
There is an external module to randomize questions in a matrix. External modules must be updated by the person or group that created them every time there is a REDCap upgrade. So usually, REDCap admins do not enable or make them available for use as they are prone to break-fix service.
I had completed data entry in "form-1" . Now I created another form called "form-2" where some of the data in "form-2" are the same in "form-1", may I know how I should assign the value from "form-1" to minimize the data entry time? Thx. I tried @DEFAULT but it doesn't seems to work.
Use a section header and pipe the field values from form-1 to form-2 if the values are fixed and cannot be changed. The idea is to minimize multiple fields holding the same value. The @DEFAULT=[form1_field] action tag requires saving form-2 and can be overwritten with a different value. If you must use an actual field and requires piping from another form with exact values that cannot be changed, use the @VALUE action tag instead.
Can you please help me with this, it's the one thing preventing me from saying "yes" to completing this for my new job, and I desperately need to do so. I need a Submission I.D number to auto populate across all my surveys, baseline, follow up, discharge... How can I do this?
Id recommend creating a submission ID Number on the first form in your project. you could use the record_id field to act as a submission ID. then, use the action tag @DEFAULT = '[variable_name_here]' with a text box field on all other forms to auto populate it. Look for the red buttons that say 'learn about action tags' it will help!
I am using a repeated instrument to allow the research coordinator (RC) to enter hours worked for our student research assistants (RA). The RC enters their name and date they are submitting the hours. The next instrument is the repeating instrument in which the RC enters the name of the student RA, the project they are working on, and up to 10 dates and the hours worked for each of the 10 dates. At the end of the survey they can opt to enter hours for another student RA. The RC wants a record of the information they entered. I would like to either (1) display Survey Completion Text that lists the student RA's name, and project on which they worked along with the date and hours worked on up to 10 dates. I can do this with non-repeating forms, but when I have repeating forms, how do I tell redcap to show data from 2 or more repeating instances? Thanks in advance!
Hi there, you're going to want to look at smart-variables. REDCap offers a few options for repeating instances, however it may not solve everything you're looking for. Also it depends on the version you are on For example you can use [ra_name][previous-instance] in your survey completion text to show the name of the previous repeat form. or [hours][previous-instance] . (im just guessing at your variable names) But the full list of commands is [variable_name][first-instance] [variable_name][last-instance] [variable_name][previous-instance] Id recommend checking it out under the green button in the form designer that says smart variables. Hope this helps!
So helpful, I made all these adjustments for my study project. Thanks!
You just blessed me! Thank you for this video with clear theaching! I suscribe for the rest!!!

Great video. I am using an updated version of Redcap that is slightly different but still pretty helpful.
Great video, thank you! Do you have any experience of using this platform for Delphi methods please?
Great video, thanks for the help, very didatic and objective responses
Awesome content. Thanks
Thank you for the video. Can you make tutorial on how to do the analysis for repeating instruments data?
Great explanation!

Hello, is it possible to set up a meeting for help with setting up a RedCap survey?
Great video thanks so much. Make tutorial for multiple languages.
