Overview of interviewees, their opinions, and the assessment of their self-perceived self-efficacy with regard to medicine use and their adherence to asthma medicine.

Pseudonym	Outcome Expectations (High/Low)	Self-Efficacy—General or in Relation to Medicine (High/Low)	Adherence to Asthma Medicine (High/Low)
IP1	High for reliever “I use it [the medicine] and then I get tremors and after half an hour it works. And I begin to feel the effect” Low for controller [2nd author: “Do you think the controller medicine would help you not experience these asthma exacerbations?”] “No, it doesn’t matter”	High (in general) “[I am] an energetic young woman who fights for good results in life that can benefit me in my future”	Low (for medicine) “I tell her [the physician] that I don’t use my medicine”
IP2	High “Now I can feel when I need to use it/…/you don’t get better by not using it [the medicine]”	High (for medicine) “The blue [reliever] I always carry with me when I am not home, but I don’t use it that often. It is mostly the brown one [controller] that I use morning and evening every day”	High (for medicine) “In gym class when I felt ill, my teacher came and said that I should sit down /…/and use my medicine /…/But now I can feel when I need to use it”
IP3	Low “Because the medicine does not give you an immediate effect. You still feel bad even after [using] the medicine. Actually it takes a long time before the medicine works”	High (for medicine) [2nd author: “Where are you on a scale from 1–10 about remembering to use the medicine, where 1 is bad and 10 is good?”] “I actually think I am about 7–8”	Low (for medicine) “Sometimes I take it [medicine] twice a day. It depends on how I feel… I actually think [my asthma] has improved over time, therefore I am thinking about quitting [using medicine]”
IP4	High for reliever, low for controller “I don’t think I see a difference in the one [controller] that I use morning and evening. But more to a higher degree with the one I use when necessary; its effect I feel right away”	High (for medicine) “[I] just put it by my bed so that I remember to use it both morning and evening. And the blue one [reliever] I always have with me in the car”	High (for medicine) “And right during my workout, I felt I needed air, but I did not get enough /…/I took my medicine right away”
IP5	High for reliever, low for controller: “I use the blue [reliever] one [mostly], that is probably the strongest [medicine]”	High (in general) “I am probably very positive. I am always lively. I always have energy”	High (for medicine) “I had started coughing/…/so I went home and took my medicine and then I went back to the party”
IP6	High “[Terbutaline, reliever]. That is [used] when I feel worst/…/if I don’t use the brown one [controller] for a period, then there can come a time where I get an exacerbation and am hospitalised”	Low (for medicine) “I am irresponsible regarding my own medicine. But I always remember my mom’s”	Low (for medicine) “With asthma, it is first when I start to feel ill that I remember to use it. Once, two months passed where I didn’t use my medicine. Not one single [time]”
IP7	Low “If I use my medicine, I will probably get better, but I probably won’t be completely asthma-free”	High (in general) “I am very strong-willed and occasionally stubborn, but at the same time I see myself as a responsible, mature and sensible young woman”	Low (for medicine) “Would say I am pretty bad at using the one I need daily. So when I feel ill, I get motivated to use it”
IP8	High “Sometimes the two don’t help, the brown and the red [controllers]. Then, it is only the blue [reliever] that helps, because it works faster than the other two”	High (for medicine) [2nd author: “Where are you on a scale from 1–10 about remembering to use the medicine, where 1 is bad and 10 is good?] “Maybe 8”	High (for medicine) “I use my medicine morning and evening”
IP9	Low “I was told that it would go away when I used my inhaler daily for a while, but I haven’t seen the effect yet. When I don’t use it for 3–4 days, I get a severe cough and breathing difficulties”	High (in general) “I am very outgoing, helpful, and can be aggressive but also friendly”	Low (for medicine) “I don’t need to do anything [to remember the medicine]. When I don’t use it my cough reminds me right away”
IP10	High “I can really feel how the medicine helps”	High (for medicine) “I use the brown one [controller] morning and evening, and the blue [reliever] when needed. The blue I also use before exercising”	High (for medicine) “I set the alarm so I remember to use my medicine”
