Is there a limit to the number of questions that can be presented for a Delphi study? There is no limit to the number of questions.
Does the platform offer an autosave feature that saves responses as participants answer each question, rather than requiring completion of the entire page? The platform immediately saves all results. Participant can return to the platform at any time to revise or finish their ratings up until the moment you close the survey.
By any chance, does stat59 offer a "branching" option in response to a statement question? 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? 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.
