Domains and themes

Quotes

Knowledge

Participants’ knowledge about their lung condition, mental health, experiences of illness and treatment, and the psychological impacts of living with both (or more) conditions

Respiratory condition and treatments

“She [respiratory physician] explains a lot to me but I still don’t understand. I know that I’ve got really bad lungs….And how long I will live with my lungs I don’t know.” (Cynthia, P13)

Mental health issues and treatments

“Well, I’ve been diagnosed with depression….Uh, I’m on, uh, Zoloft for depression….Yeah, I’m on 200mil of that per day.” (Sam, P7)

“I don’t know what anxiety is [laughs]. If something went wrong, I mean, in my day, have another beer. That’s what you did, you had another beer [laughs]. Anxiety? I don’t understand what it is.” (Derrick, P4)

Link between mental health and COPD

“It can get very frightening. Really frightening. I know when we were in Queensland for a holiday, I was sent to hospital, quite sick with the breathing. And I couldn’t breathe. And I was so frightened that I wasn’t breathing at all, because of it. And yeah, it caused a bit of a trip to hospital.” (Allen, P1)

“I’m getting short of breath. Just standing here. Maybe that’s got something to do with the pain as well, but… This is where I get depressed and think I just want to give it up. I just want to stop fighting.” (Irene, P8)

Comorbidities

““So partial asbestosis, partial emphysema and then because of the cardiomyopathy… er having the heart muscle damaged… which was unfortunate because by the time I got into hospital with the heart attack… was over an hour… um. I was not supposed to be alive, but I am.” (Neil, P11)

Misattribution

“Well before that, if I lost my breath, I had to sit down and get the fan to blow on me to be able to breathe. And now I’m taking the mirtazapine, I hardly do that anymore. I don’t have that problem. So that’s a big plus for me….I better tell them to put it up a bit more. ‘Cos it’s the only tablet that helps me breathe.” (Derrick, P4)

Social/Professional Role & Identity

Participants’ personal qualities, self-identity, or role transitions that may have been associated with the development of psychological distress

Self-identity type

“I start to cry sometime, you know. I can’t live like that. Because, to live like that, do nothing in the house, for a woman, that’s… I feel like my life is finished.” (Antonella, P6)

“I have moments… My, not my own personal thing, but about other people where I get stressed and I worry for them,… And I worry and I know there’s nothing I can do, I just think I love worrying.” (Pauline, P9)

Social influences

“It’d be one of the guys. Um, “have a smoke, that’ll make you feel better”. And, do you know, I took it up, because that was, that was the thing that, you know, obviously associated the pair of them - stress and smoking.” (Kathy, P3)

Environmental context and influences

Circumstances in a person’s life or environment which may have led to or triggered the onset of psychological distress

“When I was in my 40s and I think it was part of.…Was after I went to a lot of trouble trying to conceive. And after I stopped doing that, when my eggs failed…I was pretty down there and they put me on some antidepressants, I was on that for a couple of years, but that’s a long time ago. Like…30 years ago.” (Pauline, P9)

““I think because I just wasn’t coping with three kids under two and a half. Um and as I said, my husband was never home. And he used to go out drinking after work and you know, get home at 10, 11 o’clock at night.” (Fiona, P10)

Psychosocial circumstances

“Each one of us has a cross to bear in the house. My health, [husband’s] health, and my son’s health. We’ve all got a cross to bear, and we’ve got to tolerate each other, but when things aren’t going too good for one person - just verbal - but yelling and that, I just can’t cope with that anymore. It gets me down; very down.” (Barbara, P2)

Emotions

Participants’ reactions, feelings, or emotional state experienced as a result of living with their physical condition, mental health condition, or the interaction between both

“I used to be a bit embarrassed by it. And always I felt a bit embarrassed and a bit ashamed because people would always say to you, oh, did you smoke? [Laughs].

Optimism

Participants’ optimism or pessimism regarding the state of their lung condition, mental health, and future wellbeing
