Definition of the categories used in the qualitative analyses of Clinician views on acceptability.

Categories	Definition	Quotes
Content	Content concerned both the quality and format of the iCBT intervention and the clinicians’ perceptions of its necessity and utility for the user.	“The little stories are quite good and the kind of case studies, we liked that” (1)
		“key concepts and strategies which apply to most things” (2)
Responsiveness	Responsiveness concerned the action of writing for and responding to a user, the purpose of carrying out a review and whether it was an accurate and comprehensive manner in which to respond to the user’s needs.	“I think it was all tailored and I suppose I would, I am happy to be enthusiastic and do the extra work at the beginning and then if the person is not responding, then I tend to write less” (1)
		“I think encouragement and motivation is part of it … for them to know that there is somebody that they can ask questions to if they are feeling stuck” (2)
Relationship	Relationship concerned the perceived strength of the bond between the supporting clinician and the user.	“There were very few people I felt I had any kind of relationship with … there were people that I had on SilverCloud who I then had for individual therapy and it was essentially like meeting a stranger” (1)
		“I guess if you are writing things down, you are more measured about what you say, you have time to think about” (2)
Purpose	This category concerned the clinicians’ opinions on the iCBT package being offered and used as part of the care pathways for the clinicians and their service.	“The least it gives you is behaviours, challenging your thoughts, looking at your behaviour. It gives you all of that foundation and if that saves us two sessions within therapy across the board, that can be huge” (1)
		“SilverCloud filled the space for those people that can’t think of anything worse than sitting in a room with other people and seem much more happy doing the work on their own” (2)
