The term "hypnosis" comes from the ancient Greek word ὕπνος hypnos, "sleep", and the suffix -ωσις -osis, or from ὑπνόω hypnoō, "put to sleep" (stem of aorist hypnōs-) and the suffix -is. The words "hypnosis" and "hypnotism" both derive from the term "neuro-hypnotism" (nervous sleep), all of which were coined by Étienne Félix d'Henin de Cuvillers in 1820. These words were popularized in English by the Scottish surgeon James Braid (to whom they are sometimes wrongly attributed) around 1841. Braid based his practice on that developed by Franz Mesmer and his followers (which was called "Mesmerism" or "animal magnetism"), but differed in his theory as to how the procedure worked.
Hypnotherapy is a use of hypnosis in psychotherapy. It is used by licensed physicians, psychologists, and others. Physicians and psychologists may use hypnosis to treat depression, anxiety, eating disorders, sleep disorders, compulsive gambling, and posttraumatic stress, while certified hypnotherapists who are not physicians or psychologists often treat smoking and weight management.
To investigate the effectiveness of cognitive hypnotherapy (CH), hypnosis combined with cognitive-behavioral therapy (CBT), on depression, 84 depressives were randomly assigned to 16 weeks of treatment of either CH or CBT alone. At the end of treatment, patients from both groups significantly improved compared to baseline scores. However, the CH group produced significantly larger changes in Beck Depression Inventory, Beck Anxiety Inventory, and Beck Hopelessness Scale. Effect size calculations showed that the CH group produced 6%, 5%, and 8% greater reduction in depression, anxiety, and hopelessness, respectively, over and above the CBT group. The effect size was maintained at 6-month and 12-month follow-ups. This study represents the first controlled comparison of hypnotherapy with a well-established psychotherapy for depression, meeting the APA criteria for a "probably efficacious" treatment for depression.
It would be difficult to find an area of scientific interest more beset by divided professional opinion and contradictory experimental evidence…No one can say whether hypnosis is a qualitatively unique state with some physiological and conditioned response components or only a form of suggestion induced by high motivation and a positive relationship between hypnotist and subject…T.X. Barber has produced "hypnotic deafness" and "hypnotic blindness", analgesia and other responses seen in hypnosis—all without hypnotizing anyone…Orne has shown that unhypnotized persons can be motivated to equal and surpass the supposed superhuman physical feats seen in hypnosis.
Look for a hypnotherapist who is a member of the American Society of Clinical Hypnosis (ASCH) or the Society for Clinical and Experimental Hypnosis. To be a member of either of these organizations, a hypnotherapist must have a doctorate level degree in medicine, dentistry, or psychology, or a master’s degree in nursing, social work, psychology, or marital/family therapy plus a specific number of hours of approved training in hypnotherapy. In some cases, accredited, doctoral-level practitioners of alternative health care, such traditional Chinese medicine, may also be approved for membership. Of course, in addition to looking at qualifications, you should also find a hypnotherapist with whom you feel confident and comfortable in a therapeutic relationship.
