In the U.K., there is a version of online CBT for depression called Beating the Blues, which became popular despite only being available by prescription. “They would write you out a prescription with a web address and access code, and you’d be able to access that...”
Is there any clinical reason for doing such a thing?
I'm not sure what you mean by "clinical" in this context, but I don't think the prescription thing was a charade to add some extra placebo effect. Rather, it was probably because once you start claiming to treat depression, you are regulated like a prescription drug.
In case it's not clear from the context, you don't need a prescription for Joyable either.
MoodGYM is a terrific alternative with a somewhat different focus. If you're not sure which is for you, I recommend you try both for free (MoodGYM is free and we have a 7-day free trial). Here are a few major differences:
(1) We give you a personal coach. Our clients say their coaches are key to their success, since one of the challenges of CBT is finishing it.
(2) We are specifically focused on social anxiety and tailored to be most effective for people with social anxiety.
