Live studies work best when joining is simple and participants know exactly what to do next. Keep the setup boring, test it once as a participant, and have a backup plan for late arrivals.
Plan Timeslots and Recruiting
- Use multiple timeslots when you need different groups, time zones, or smaller sessions.
- The current live-study show-up rate is around 70%, so over-recruit a bit if you need a fixed number of participants in the room.
- You do not need to pay no-show participants.
- Any reserved funds that are not used are returned after the study is reviewed.
- For live studies with multiple timeslots, the quota is distributed proportionally across each timeslot.
With a Moderator
- If you need everyone in the room first, use a Zoom link as the external study link. Share the real experiment link in Zoom when you are ready to start.
- Open Zoom early. Check screen sharing, audio, and the participant list before the start time.
Without a Moderator
- Write instructions as if no one will be there to explain the next step.
- Only put the real study link directly in the external link if the study can start and end without someone controlling the room.
- Set multiple timeslots if participants need to show up at specific times but no moderator will be present.
Async studies are usually best for surveys and individual tasks that participants can finish on their own schedule.
Qualtrics Studies
- Use URL parameters so the MobLab participant ID is passed into Qualtrics.
- Redirect participants back to the MobLab completion URL at the end of the survey.
- For screen-outs or failed attention checks, use different manually specified completion codes to mark different cases for now. These codes are useful identifiers when you review submissions on our platform. If the completion code does not match, the system will not assign base payment automatically. Multiple completion-code support for automatic processing is planned for the future.
- For setup details, see the Qualtrics Integration Guide. For partial completion handling, see Handling Partial Completions and Screen-Outs.
