Incentive for rating physicians

Type of Factor	Code	Example Quote
User Specific	1. Very positive or very negative experience	“So I think that would be the two extremes. If I was totally delighted, if I had been to a physician and thought, wow, I never experienced that. They were so friendly, great physician, then I could imagine [rating the physician], or if I experienced the exact opposite and thought that wasn’t appropriate at all.” I09
	2. Confidence in anonymity of the evaluators	“Yes of course. Obviously, I would place a lot of value on any kind of anonymization.” I16
	3. Responsibility to provide feedback for the benefit of others	“Well, obviously, I contribute to this. Because I find it important that information is shared.” I02
PRWs Specific	4. Clearly defined criteria for evaluation	“Because you know, if I get scientifically prepared survey, I have the impression that they know what they want and then I can rate.” I12
	5. Rating process simple and fast	“It has to work fast and easy. And there must not be too many questions.” I03
	6. Ability to provide rating via mobile apps	“As I said regarding the low threshold, just for an example, that it is included in another app. Yes, it would be the best, if I had it on my mobile phone, but most websites are still fixed so that you can only see it on a huge computer screen, but my generation are rather mobile-app-users.” I10
Physician Specific	7. Pro-active request to provide feedback	“If the physician said, there is a physician rating website and I would like to ask you leave your opinion there. Then I would probably do that if I had time.” I11
