PAa after breast cancer
	Levers
		Physical	Physical benefits and previous practice are important levers	Physical benefits 5/9; Previous practice 4/9	And there is another thing that is beneficial too; it’s that I have a lot of joint pain. And indeed, when I move, it hurts less. [Sylvie, 50 years, working part-time] So, it helps the fact that was doing a little bit of physical activity before getting sick. [Rose, 47 years, working part-time]
		Psychological	Oncologist’s recommendation is an incentive	4/9	So, indeed, it’s the oncologist who told me and this made me want to move: “Well, you are tired, there aren’t a hundred options: it’s physical activity!” [Anne, 60 years, sick leave]
		Social	Doing it in a group, with friends, or with relatives are seen as levers	4/9	Because me too, I like doing it in a group. Otherwise it’s hard for me to do physical activity. [Christine, 39 years, working part-time]
		Organizational	Planning PA sessions to fit PA in the daily regular schedule is helpful	Planning PA 2/9	When I come home from work at night ... I feel really exhausted ... So I’m lucky to be able to do physical activity at work at lunch time. [Rose, 47 years, working part-time]
	Barriers
		Physical	Late effects of cancer treatment can negatively impact the practice	Late effects 9/9	And regarding fatigue level, after the end of primary treatments, I was at 10/10. Today, I don’t know, I may be at... it decreased though: I’m at 6/10. But still always with this permanent exhaustion feeling, it is hard to exercise. [Rose, 47 years, working part-time]
		Psychological	Lack of motivation is a main psychological barrier cited	3/9	I’m really not motivated at all. [Sandrine, 44 years, working part-time] So me, I try to do it. But motivation is not always there. [Sylvie, 50 years, working part-time]
		Organizational	Lack of time is a main organizational barrier cited	2/9	But I don’t always have time... It’s also a lack of time. [Rose, 47 years, working part-time]
Use of mHealth
	Lever
		Psychological	To be able to know how many steps a day and track the activity they do is associated with motivation and facilitates the use of these strategies	3/9	It’s a tool that allows us to see what we are doing, either when we don’t do a lot, or when we do a lot. [Sylvie, 50 years, working part-time]
	Barriers
		Psychological	Some patients are not familiar or interested in mHealth, which can be a barrier to their use	6/9	I think I have a friend who has one. But I have never asked for more details. [Marie, 46 years, full-time] I’m not really interested about that. [Marlène, 29 years, sick leave] Oh, me, I’m not a “connected device” person. I’m not a geek at all. [Anne, 60 years, sick leave]
