Hi,
as holch said:
The best is to put the question of Sx and Qx into one group.
This is easy to randomize.
If it is really necessary to display Sx and Qx separately you have to use "question by question"
That's something we desire: A better grouping concept, nested groups or so.
Each Questions-group starts with a (randomised) ending of the story which could influence the answer to the one question in the Stories-group,
I don't understand this.
How can this randomized ending of the story influence the answer in the story group.
I think the Story group is always asked before the Question group.
Anyway, to understand better and be able to advise something else, send a sample of your survey.
