There are two use cases where you might want to reuse the same participants for a study.
First, you know up front that you want to use the same participants for a two part study.
Second, you may not plan to have the same participant take a second study. For example, Charlotte took an unmoderated study and said some interesting things. Now you're looking to do a follow up session with Charlotte to share some new designs.
If you fall into the first case, make sure to add a screener question to first study. Similar to this one:
When you are ready set the first part live, please chat our customer chat support. Customer support is the blue button on the bottom right of the PlaybookUX website and the PlaybookUX app. Here's an example chat that you can send!
Here's the message for reference:
Hey! I set up a two part study and I'm ready to launch the second part now. Can you please invite the same testers from the first study called "Medium usability study" take part in the second study called "Medium usability study V2"? Thank you!
Our team will make sure the participant is routed to the second part of the study after completing the first part.
In the second use case (where you don't know before the first test that you are looking for a repeat tester) you can send us a chat that looks like:
Hey! I had a few testers that did a great job and I'd like to invite them to participate in our second round of testing. I'm ready to launch the second part now. Can you please invite the testers Charlotte, Nicole and James from the first study called "Medium usability study" take part in the second study called "Medium usability study V2"? Thank you!
Please note, we will reach out to the testers you requested. However, we can't guarantee they will be available to test the second version. Most testers are happy to participate a second time but they can't always participate due to scheduling conflicts.
However, if you've set up the study as a two part study up front and added the screener question shared above, that will guarantee you receive the same testers for both studies.
