Hello, everyone. I am a masters student working on the online survey for my thesis. I have all of my materials ready to submit to IRB and then I read on my university web page that participants in online surveys must be able to go back and change their responses. I went to make this edit in my survey, and it did not work because I have randomization within my survey. I not only have randomization within blocks, but also between blocks, which is something I would like to keep in my survey to control for order effects. I already called support and essentially the only way to add a back button is to delete all of my randomizers.



There has to be another way/work around! How are we supposed to present a randomized survey that allows participants to change their responses? I do not want to sacrifice randomization for a back button, but I know I will not get passed through IRB if I do not allow this function. Please share your tricks with me!
