Credibility aspects and examples of these aspects

Aspects of Credibility	Justifications from “think aloud” sessions
Status of the site or contributors	“I’m going to go to the Mayo Clinic website on the common cold because Mayo Clinic seems like a really kind of trustworthy place.
	“I’d probably click on flu and, oh, the first one says flu.gov. So, a government site might have some accurate information.”
Site design	“So usually, maybe I’ll look and see the first couple sites that come up if something sticks out to me as looking more professional, I would go with that.”
	“This kind of has cute little pictures and stuff and it shows a person with the stomach flu like they have stomach cramps.”
Familiarity or resonance with the participant	“Heard of this website.”
	“Familydoctor.org, health forum, meningitis. That sounds like that rings a bell.”
