I have a study with 64 benefits and 4,000 respondents. I would like to test benefits via MBC, but how do I prevent people from selecting most/all benefits on each screen. There is no cost associated with benefits-we are just testing availability effects. Do you typically include text (please select only benefits that you would really use)?
Is selecting too many benefits a problem when there is no cost associated with them?
Can MBC handle 64 on/off benefits with 4,000 respondents? Benefits can be nicely organized to logical categories.
