Many psychological problems are maintained, in part, by dysfunctional response expectancies, and changing those expectations is an essential part of treatment. Hypnotic inductions alter response expectancies and have been shown empirically to substantially enhance the effects of psychotherapy. Therefore, hypnosis can be used therapeutically as a nondeceptive placebo. Expectancy plays a major role in hypnotic inductions and their effects. Clinical procedures suggested by these data are explored.
