Theme #	Theme Description	Example Quotes
1	Trust in the Referring Physician	Quote 1A: “I like my doctor immensely and trusted her, and she gave me the wide berth of discussing it (screening) and then when I came back for the next visit…we discussed it some more. She’s an awesome doctor that trusts me, but also encourages me to do the right thing. I think it’s a lot in having trust in your doctor and the way that they broach it.”
1	Trust in the Referring Physician	Quote 1B: “They should never belittle you or put you down, because that doesn’t help you accomplish what you need to do. And nagging doesn’t help you either, but they need to talk to you and show real concern and let you know—like my doctor did honestly with me—about my odds.”
2	Early-Detection Benefit	Quote 2A: “Even though I am very active and have great health—vitals and everything—I have a concern and actually a fear that I will get lung cancer…it (screening) would detect it (lung cancer) if I had it, and perhaps save my life by catching it early”
2	Early-Detection Benefit	Quote 2B: “Early diagnosis of any significant lung disease would be a huge benefit. The earlier you find it, the better your chances of treating it.”
3	Low or Limited Harm Perception	Quote 3A: “Harms? I don’t see any harm in it (screening). The harm would come in not doing the screening.”
3	Low or Limited Harm Perception	Quote 3B: “I’ve heard about overexposure to radiation and I didn’t want to do that. And then…the doctor told me about the low-dose aspect of this and it was a very minimal exposure, so that kind of made up my mind that it was worth giving it a shot.”
4	Friends or Family with Advanced Cancer	Quote 4A: “I told her (doctor) I wasn’t going to go through what my mother did. My mother had lung cancer. They gave her chemo and radiation. I think it’s a terrible, terrible sickness.”
4	Friends or Family with Advanced Cancer	Quote 4B: “My father died of lung cancer, and my husband died of lung cancer. So when the doctor suggested this (screening), he didn’t have to do very much with me—I said yes I’ll do it.”
