[Triennial experience in group hypnosis therapy and the teaching of medical self-hypnosis].

A three year experiment with group hypnosis therapy for the teaching of medical self-hypnosis is reported. The teaching was divided into 7 courses followed by a total of 142 pupil-patients. The self-hypnotic techniques employed maximised motivational and gratification factors. A special type of deep-breathing is also described. This at least partially solves the problem of inducing a sufficiently deep trance for the achievement of appreciable results. Its efficacity was confirmed in almost all the patients despite the number and diversity of their problems and varied motivation.
