I'd recommend checking out Barlow's (2018)
Unified Protocol for the Emotional Disorders. It's an innovative, integrative CBT with a mindfulness component.
Progressive relaxation which, was its
own behavior therapy, and breathing re-training are principal components of
mindfulness-based CBT and
prolonged exposure. The linked therapies are all evidence-based. Also, of course,
DBT has a mindfulness component as well.
One of the reasons I'm drawn more to hypnosis, the
Ericksonian form, is the tailoring of these rituals into what the patient believes is valuable. For instance, I have many patients who roll their eyes when I mention "box breathing" but get excited if I urge them to become absorbed into
their thing (e.g., rock-rock climbing, yoga, trance music, etc).
