Heuristics | Definition | Example from “think aloud” interview |
---|---|---|
Prior clinical or symptom related experience | previous interactions with a health care provider, prior experiences with symptoms (self or familiar other) | “I would—this would probably be where I would reflect on what my personal experience would have caused me to feel this way, and I would—if I started feeling really terrible” |
“Then I’ll search for symptoms of the flu, because I didn’t get my flu shot, so I have to look into that.” | ||
“I want to check silent migraines, sometimes I get those, and see what happens and why it triggers it.” | ||
Credibility of information source | recognition of information status or contributors to the website, organization or format of the website, and resonance with participant | “We're going to go to CDC for seasonal influenza because I feel like that would be a beneficial type of information.” |
“I’m going to use Wikipedia, even though it’s frowned upon.” | ||
“I’d probably click on flu and oh, the first one says flu.gov. So, a government site might have some accurate information.” | ||
Internet story coherence | consistency in information presented with own biases, vignette symptom definition, prior history with symptoms, or information obtained during search | “This is sounding a little bit closer to what I’m experiencing.” |
“And this is pretty much where I would probably stop because it says right here the common cold, bronchitis or a viral syndrome.” | ||
“There’s a lot of the same or the similarities between the flu and my symptoms, so I’m going to keep that on the table and think that maybe I have the flu, but go look at some other diseases.” |
