Well just say I am finding it difficult, in that I didn't want to reenter this particular conversation, but..
Not being well versed in psychology and specific therapies /techniques , is there a difference between CBT and AVRT other than trademark registeration? It seems to me that AVRT is more specific in nature, but I could be wrong, obviously. In a nit- picky nuance-y way I would say I think that one would have to identify behavior and troublesome in more depth , to determine if AVRT would be helpful or perhaps if it would be the most helpful in a given application.
Like I have said, to me, the troublesomeness of the OP stems from the proscription of the behavior, eg it would not be troublesome outside of the 'artifical' particular proscription. And again coming at it from a very secular position.
