My new co-investigator is wanting to propose to do conjoint (traditional CVA possibly, or possiblyCBC, we haven't decided) as part of a telephone interview. I don't think that telephone administration is really feasible, except as Green and Srinivasan described as the telephone-mailed-telephone. It is a CBC, it would just be 2 alternatives (different medication therapies) so maybe not impossible.
I can't find any literature on just plain telephone administration, and it seems dicey to me. Any thoughts by anyone?
