Illustrative quotes related to using the self-management app: nutrition management.

Id	Concern	Interviewee	Quote
N1	Adjusting diet	10-year-old teen, C4	“I looked at the calories often because then I could see how many calories I needed, and how many calories I was below the goal. [...] I drink more milk now for the breakfast.”
N2	Getting more disciplined	Mother of a 5-year-old child, C5	“The app helps you to be more disciplined with the food, and controlling nutrients makes you follow a more balanced diet. It has helped us to make his meals more balanced.”
N3	Nutritional goals as a game: educating young teens	Parents of an 11-year-old child, C6	“He eats less than necessary, and we put a lot of effort in pressing him to eat what is recommended by the dietician. So, the app helps our son to understand why we put a big pressure on him to eat. Sometimes it is very difficult to make him understand how important the amount of calories is. I would say it is like a game, you add your meals at the end of the day, you see the amount of calories and the distance to the goal. It was very useful in letting him understand he needs to eat more.”
N4	Need for HCPa support: not reaching goals	Father of a 3-year-old child, C2	“We saw that it was quite difficult sometimes to get this right amount of energy, fat or things like that. [...] We checked with the nutritionist. She told us that it was OK with the things that we are giving him right now.”
N5	Disadvantages: obsession with goals, need for individual tailoring	Dietician, C6	“Yes, they liked it, but, in some cases, they were obsessed about the goals. Patients who have a good nutritionals status, like this information. They are concerned about the nutritional status. If the patients have problems with nutrition and see every day that they can’t reach the nutritional goals, it is bad. It is important to adjust the goals to every patient.”
