Findings and recommendations from usability testing.

Observation feedback from usability testing	Revision in the communication module
Participants were not clear that they could move between four tab pages by clicking on the “tab” interface.	Directions were added at the beginning of the tutorial to explain how to move between tabs. The titles on each tab (i.e., Presenting Information) were also highlighted and underlined to indicate that they are clickable.
Participants had problems using the interactive question prompt list.	Additional text and step-by-step graphic of the functionality of the interactive question prompt list were added at the beginning of the component to demonstrate how to review, select, and print sample questions.
Participants were not clear that they can click on the role-modeling video clips.	We added a “Watch Video” button under each video clip so it is clear that clicking on the button would start the video clip.
Participants were unsure how to move to the next page on the PACE content.	We added “To read more, click “Next” below” over the Next button, along with a directional arrow.
Participants were unsure how to go back to the previous page after opening up a new subcomponent.	We added a “Close” button at the upper right corner of the each popped up subcomponent. Once they clicked on the Close button, participants would be brought back to the previous higher-level page automatically.
