Table 3.

Quotes from the therapist consultants (n=10) during think-aloud testing.

Theme	Quote
Enjoyment	I like the visuals… It is attractive to use The gamified elements make it more enjoyable This is definitely more enjoyable and accessible than conventional CBT for psychosis
Usability	I like how simple it is… It’s a nice scaffolding tool I like the bar along the bottom to help with time management I feel more confident to be flexible given my experience level... I worry that low intensity therapists would struggle to deliver in a flexible manner
Usefulness	The structure scaffolds good CBT… you can be more focused on the person in the room The formulation feels personalized It gives such a clear focus for both therapists and client I think it makes [the therapy process] less intense for people who struggle with conversations for an hour
