Dear Michiel,
I have defined some attributes based on the real context and some others based on a hypothetical scenario. The idea is to show the real attributes and ask respondents to select an alternative and then show some new attributes while the previous attribute levels and alternatives are the same as the first choice to investigate how the new setting may influence their second choice. Could you please let me know how I can design such a survey?
Thanks for your support.
Best,
Peyman.
