Hypnosis as an Adjunct to Cognitive-Behavioral Psychotherapy: A Meta-Analysis

A meta-analysis* was performed on 18 studies in which a cognitive-behavioural therapy was compared with the same therapy supplemented by hypnosis. The results indicated that the addition of hypnosis substantially enhanced treatment outcome, so that the average client receiving cognitive-behavioural hypnotherapy showed greater improvement than at least 70% of clients receiving non-hypnotic treatment.

Effects seemed particularly pronounced for treatments of obesity, especially at long-term follow-up, indicating that unlike those in non-hypnotic treatment, clients to whom hypnotic inductions had been administered continued to lose weight after treatment ended. These results were particularly striking because of the few procedural differences between the hypnotic and non-hypnotic treatments.
