Think-Aloud Interview Script Questions and Probes

Explain the think-aloud to participants. Script/key points:
• We will now watch a video of your doffing. In as much detail as possible, talk us through it as we watch:
○ Explain the process to us as if we were complete doffing novices or lay people.
○ Describe what you were thinking and paying attention to at each step of the process.
○ This will help us understand critical moments and identify common problems in doffing.
• If you’d like to stop or rewind the video, just say “Stop.” I may also stop and ask follow-up questions.
Let them talk and, as necessary, ask probing and follow-up questions:
• Could you describe what you were thinking when you performed this task?
• What were you paying attention to here?
• What was the obstacle/what issues did you have here?
• What made this part easy/hard for you?
• Where, when, and why do you think you self-contaminated?
• You may have noticed that we asked you a question during your [first or second] doffing. a
○ Do you think that affected your performance doffing? How?
○ Did that interrupt your workflow?
○ Did it interrupt your thinking?
○ Did it increase your mental workload?
