Hello, I have 15 vignettes that participants will rate on a scale of one to 10. Each vignette is a block. I want the 15 vignettes to be randomly assigned to three accountability conditions (five vignettes per condition). Each condition is a block which is also randomised so all participants are exposed to all three conditions just in a different order.
Randomising the three conditions works fine – I randomise for all three conditions to be shown. However, I am not sure how to treat the vignettes. Currently I have all 15 blocks randomised under each condition block but this means I am getting duplicates across conditions because each set is randomly selected from the total group of 15 vignettes each time. I want each vignette to appear only once across all three conditions – randomisation but without repeats. Is there a way to do this?
I also want to make sure I collect all data about the order and condition for each vignette per participant – so any tips on making sure I get this right would be a big help. Thanks in advance for any help you can offer.
How to stop duplication when randomising vignettes within randomised conditions
+21You can add the display logic to the survey flow for each block using the question whether it is displayed or not.
Thanks so much for taking the time to respond to my question. I took your advice and looked at using display logic but it doesn’t seem to help prevent the question/vignette blocks repeating in the second and third conditions (or I was doing still doing something wrong!). A colleague came back and said he didn’t think it was possible within Qualtrics so has written some javascript to deal with the issue and it is now working.
