Hello everybody, Qualtrics newcomer here :)
I am looking to design a Longitudinal Survey where participants are initially randomized into a block using a block randomizer. Each block contains only one question, which is randomized in each iteration with a certain number of fields through the loop and merge feature. I want to know how I can record the ID of the loop and merge that the participant encounters and keep a record of it. In a subsequent survey, I want to use this record to extract the same question, ensuring that the participant answers the same question.
I am aware that participant IDs can be recorded using XM Directory, and the corresponding block can be extracted in the survey flow using the authentication feature. However, I am unsure how to extract the specific fields of the loop and merge question.
How can I do this?
Thanks a lot!
