Hypnotherapy is a form of psychotherapy used to create change in a patient while in a state of sleep, or unconsciousness, known as hypnosis. The word hypnosis comes from the Greek word “hypnos” which simply means, “sleep.” The therapy itself uses guided relaxation techniques from a trained hypnotist that invoke feelings of intense relaxation, concentration, and/or focus to achieve a heightened state of awareness or trance-like state.
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.
During a hypnotherapy session, the therapist will bring you into a state of deep relaxation in which the critical, conscious part of your brain recedes and the subconscious mind becomes alert and focused. The therapist will make suggestions, based on your intended goals, that will take root in your subconscious mind. These suggestions should affect your thinking in a positive way and empower you to make change.
It is used for a wide variety of applications, and studies into its efficacy are often of poor quality which makes it difficult to determine efficacy. Several recent meta-analyses and systematic reviews of the literature on various conditions have concluded that the efficacy of hypnotherapy is "not verified", that there is no evidence or insufficient evidence for efficacy.
