Participation in multicomponent hypnosis treatment programs for women's weight loss with and without overt aversion.

Studies of hypnotic, covert and overt aversive techniques have yielded equivocal results when each has been examined for a singular effect on weight lost. Some have advocated study of effective combinations of techniques before investing in other applications. Two programs of hypnosis, imagery, diet, tape, behavior management and support but differing in the overt use of aversion (electric shock, disgusting tastes smells) were examined. A total of 172 overweight adult women were treated, 86 in a hypnosis only and 86 in an overt aversion and hypnosis program. Both programs achieved significant weight losses. Although subjects who received overt aversion attained somewhat more desired goals and lost more weight than subjects recovering only hypnosis, the differences were not significant.
