Use current results from prior participants in the survey (delphi Survey) | XM Community
Skip to main content

Hello! is it possible in Qualtrics to use the other respondents' answers in a survey/survey flow?
Use case would be Delphi surveys, in which participants are asked twice how likely an event is. After the first time, the average likelihood is calculated and used for a second round (You answered X, average answer is Y. Do you want to change your oppinion). Can this be realized in Qualtrics?  Wouldn't this be a valuable addition to Qualtrics? Currently, we have to use (quite limited) third party tools for this.

I have the same question! lipflip did you find how to do it?
Thanks

Hello,
I also have exactly same question. Could you find a solution? I am even not sure what third party tools exist to do this.
Thanks

This could be accomplished with a couple of web service scripts and a database table:

  • Get the participant's and average likelihood for the last round at the beginning of the survey

  • Save the participant's likelihood for the current round at the end of the survey

I also have the same question.  It doesn’t seem like there has been much progress in the three years since the first post?

@TomG could you please expand the explanation of the solution you proposed?

Thank you!

You would use a web server with a database to store the applicable data for each respondent and round.  At the beginning of the survey you would do a web service call from the survey flow. The web service would query the database and return the summarized data (e.g., average) from the previous round into embedded data fields.  At the end of the survey flow, you would another web service call. That web service would save the applicable respondent data for use in the next round.
