This blog seems to be the origin of a quote that has been widely copy-pasted by many hypnotherapists:
American Health Magazine reported the following findings from a recent study.
• Psychoanalysis: 38% recovery after 600 sessions
• Behavior Therapy: 72% recovery after 22 sessions
• Hypnotherapy: 93% recovery after 6 sessions
(As far as I can tell, American Health shut down in 2000, so it wouldn't have been that recent...)
Recovery from what is not stated, and searching elsewhere reveals at best only a small (often insignificant) improvement using hypnosis versus more conventional treatment. What are the origins of this claim?
