Randomly assign people to conditions in a longitudinal study | XM Community
Skip to main content

Hi all, 

 

I’m doing a longitudinal study (one time per week for 3 weeks). People will be assigned into a random condition (1 of 5) the first time they participate. How can I have it so that people who access the study again for the next time points will be in the same condition?

For example, say Person A has been assigned to Condition 1 the first time they participate. How can I ensure that Person A will see the stimuli for Condition 1 (and not any of the other conditions) the second and third time they participate?

 

Thank you in advance!

Post the first entry you can update an embedded data with the choice that was selected along with first entry of respondent in 2 different embedded data with XM Directory Task.

Later on second entry of respondent skip randomizer for them with branch logic and use hardcoded embedded data to show them block of questions with branch logic.

Hope it helps!
