Affordance	Heuristic	Cue	Examples
Modality

		Visual
		Text	“I was reading [subtitles] as she was talking” (P48, FG4, VER1).
Agency
	Trustworthiness
		Voice	“Her voice was so convincing. You could just ease right into it” (P34, FG7, VER3).
		Friendliness/likability	“Make her a little more friendly” (P47, FG4, VER1).“Happy, very happy. You have some people talk to you, they want to show happy, but you can see the other side. All I see was happiness in her” (TA33, VER 3).
		Appearance	“I don't wanna go to nobody looking all weird and start asking me questions” (P91, FG1, print).“Eyes were funny,” and “[she] could be a little bit easier on the eyes” (P38, FG3, VER1).
	Expertise
		Authority	“I want it to come from a doctor, that's my opinion. Nurses don't know…that's why they're a nurse...” (P48, FG4, VER1).
		Clothing	“The scrubs, I mean they're bland. Everybody wears scrubs that aren't doctors” (P103, FG2, print).
		Age	“She sounded young…too young to be a doctor giving us this important advice” (P44, FG4, VER1).
	Content
		Novel	“It said you would [test] annually, every year, for the FIT. I didn't think you would have to do it that often” (P33, FG3, VER1).
		Confusing	“If it's loose [stool], do you do the same thing?” (TA34, VER3).
		Consistent	“I trusted what she was sayin’ and mainly because I had gone through it…proving most of what she said was true all the time” (P135, FG8, VER3).
		Understandable	“It wasn't like with all these big words that I can't understand at all…even a child could understand what she was saying” (P133, FG8, VER3).
		Missing	“It was basically saying, look, there's this nifty new FIT thing that you can do at home…But it didn't really explain why [to choose FIT over colonoscopy]” (P44, FG4, VER2).
	Social presence
		Movement	“The movements of her hand—usin’ her hand figuratively…a lot of people talk like that. That was really human, and actually they're easy to understand when she does it” (P133, FG8, VER3).
		Fake versus real	“It's not real…I'll interact with you [moderator] not her [referencing VHA]” (P91, FG1, print).“It's more lifelike…like a real woman” (P132, FG8, VER3).

Interactivity
	Social presence

		Responsiveness	“They asked you a question, what was your reluctance to having the test…You have to pick one, and if you didn't pick one it just sat there and stared at you” (P32, FG3, VER1).
		Ability to ask questions	“I might need to wanna’ know something before I go off and take this test…[There's] nobody there to answer the question for you. If I don't get an answer, why would I sit there and listen to that then?” (P118, FG5, VER2).
Navigability
		Ease of navigating	“Nobody likes technology when they're a certain age, and this is just easy…you just plug in, listen, and it was really simple” (P113, FG5, VER2).
		Transitions	“It's very user‐friendly, but there's no back button to review or make corrections. I inadvertently hit ‘yes’ for smoker, and I've never smoked a day in my life, and of course you can't go back to make that change” (P32, FG3, VER1).
