Mobile health characteristics
	Perceived ease of use	8	“The platform (for professionals) is easy to use, very practical, quick and intuitive”; “Patients found it (TCApp) easy to use, simple, and they learned fast how to use its different functionalities. They have never asked for more explanations than those given at the beginning."
	Perceived usefulness	8	“I value the immediacy of the instrument and the ability to advance visits when things were not going well a lot...I believe that the app can be a good tool for therapists. They can have information prior to their face-to-face visits.”; “The app facilitates our clinical practice a lot...The whole team feels more reassured with regard to each patient´s treatment”; “I value the possibility to give patients quick and valuable information (mostly resolve their doubts) during the time in between their regular sessions or advance visits, when there is something worrying in their records or messages...By doing so, we can also reduce the amount of visits of our patients to the emergency department”; “The online chat provides very valuable information as it facilitates contact with patients in-between sessions. However, it does require more time to explore and exploit the potential of these messages and how to use the information provided by each patient in face-to-face sessions.”
	Design: Platform	8	“The platform is attractive and does not overload visually”; “The possibility to receive photographs of the patients’ meals is great!! I like how the food records described with words appear in the same screen next to the meal photographs.”
