B. MODERATOR INSTRUCTIONS
Thank you for sharing your previous experience and some of your preferences with me. Now let’s move ahead and take a
look at the ClinicalTrials.gov website: https://clinicaltrials.gov/. I’m going to drop the link to the website into the Webex
chat. Please let me know if you have trouble locating it. Once you receive it, please feel free to click it open directly or
copy and paste the link into a browser of your choice.
Now that you have it up on your screen, the next step is for you to share your computer screen with us so that we can
observe how you navigate the site. To share your screen, look for the “Screen Share” button on the bottom of your
Webex window (next to video and looks like a document icon).
C. PARTICIPANT TASKS
C1. Now we’re on the homepage of the ClinicalTrials.gov website.
C1a. Without clicking on anything just yet, can you tell me your initial reactions to this site?
C1b. What does the appearance of this page tell you about the site’s purpose and its creators?
C1c. What kind of information do you see here? What do you think you can accomplish on this site?
C1d. If you were exploring, what would you click on first?
C2. Next, I am going to ask you to complete various tasks on this site. Remember that there are no wrong answers. If a
task is difficult to complete, that just lets us know that certain areas may need to be improved. Please remember to think
aloud as much as you can. You can let me know when you feel you’ve accomplished the task.
