ANSWER: There is no limit to the number of questions.

By any chance, does stat59 offer a "branching" option in response to a statement question?

ANSWER: We do have branching options on our normal survey modules, but not on the Delphi module. Normally Delphi studies require all participants to answer all questions.

Where can I find the threshold for determining if "consensus" has been reached for statements in a delphi study?

ANSWER: You will not have direct access to view the consensus thresholds. Generally, these are pre-set at a standard deviation of <= 1.00 on the 1-7 scales, and >=67% of experts choosing the same response on the other scales. We can change those on the backend if you need to use other cut-offs. We strongly suggest using the 1-7 scale and the SD <= 1.00 as your rating scale, as we have studied and published on the reliability of this method. View
