I’ve just written an app to allow researchers to host their PI sheet and debrief on my site (written in markdown), which has the advantage of a download link for the PI sheet before and after the study. Participants are also able to withdraw their consent at the debrief stage which sends the researcher an email but the participant stays anonymous. Hosted studies will be listed at the link above (in random order) or an individual study can be addressed using a variable (e.g. https://moryscarter.com/vespr/portal/index.php?expt=1)
I’ve created this with free functionality plus additional licenced features of counterbalancing groups taking into account participants who did not complete, the ability to reset the participant number (while maintaining a separate unique session id), plus getting priority on the study list.
Registration is free and I’ll be adding features such as passing through variables untouched and integration with Sona and Prolific for credit granting. Please let me know if you have any requests. I’m also happy to add logos for individual institutions as well as template PI sheets (if you convert them to markdown for me).
New Feature 18 April 2021
On your edit study page you will see the number of participants allocated to each group split into confirmed (they reached the debrief page), in progress (they started less than 12 hours ago), lapsed (they started more than 12 hours ago) and withdrawn (they withdrew consent at the debrief page).
The output looks something like this:
New Features 20 April 2021
Licenced users can set a study to inactive which displays a bespoke message instead of the PI sheet.
The number of hours between when a participant starts and when they get marked as lapsed so their group can be reallocated is now configurable.
New Feature 23 April 2021
If you add a consent statement to your experiment then a check box will be displayed to participants which must be ticked to reach the experiment.
New Feature 26 April 2021
You can ask completed participants to send the researcher their email address via a form on the debrief page, for example for entry into a prize draw. The email address is not stored and the researcher is not told the participant’s id or session numbers.
New Features 1 July 2021
You can now use a Qualtrics preview link as your study URL. When you switch your study from piloting to recruiting, your participants will automatically be sent to the anonymous survey link instead of the preview link (by replacing /preview/ with /form/ and removing ?Q_CHL=preview&Q_SurveyVersionID=current from the URL).
If you assign groups during your experiment rather than using the portal (e.g. based on the response to a question), you can now send this information back to the debrief page so you can easily view the number of participants in each group from your study configuration page.
The instructions for anonymous withdrawal at the debrief and the message shown to participants who don’t consent at the start are both now customisable.
New Feature 23 July 2021
The researcher can now see the maximum session number for pilot participants, the minimum session number for live participants and the individual session numbers for withdrawn participants on their experiment admin page.
New Feature 16 August 2021
Ballot stuffing has been disabled for clicking on the credit link and sending your email address to the experimenter. You can test this using a demo participant which you can reset.
New Feature 23 August 2021
If you want to skip VESPR’s PI sheet and launch the experiment with a direct link then start by ensuring that your consent field is blank (so there is no consent statement to agree to) and then use the URL to https://moryscarter.com/vespr/portal/launch.php?expt=x where x is your experiment number. N.B. This method does not currently permit an id variable to be passed through.
