Carrying Participant ID from Qualtrics, to Pavlovia, and back to Qualtrics

Online experiments

Hi sorry, I have a few more questions I was hoping you could help with.

  1. You had a post in this thread saying that you used a branch to have participants come back to the same Qualtrics survey after finishing the Pavlovia experiment. Where did you put the branch? Right now, I have some survey question, then a link to the Pavlovia experiment on a Qualtrics page, and then put a branch after that to branch to the end of the survey if var = 1, which I define in the completed URL from Pavlovia ( I have $"https:// ... ?var=1&id="+expInfo['participant']for the URL). Does this work or am I doing something horribly wrong?

  2. Relatedly, I’ve had one participant so far and she said that there was an error when she clicked to end the Pavlovia experiment. She said it brought her back to the ‘initializing experiment’ screen like it was starting over. Do you know why it might be doing that?

  3. The output file from Pavlovia doesn’t have the participant ID from Sona or Qualtrics. Under the ‘participant’ column, it just says “{e://Field/id}”. So it looks like it might not be transfering correctly from the link?

I’ve been making this Sona --> Qualtrics --> Pavlovia --> back step-by-step as I go along. I was planning on sharing it with you to share with others once I figured it out, but it will also help now to show you exactly what I’ve done so far. Thanks for your help!
