Dr Alfred A. Barrios conducted studies that compared the effectiveness of achieving long-term positive changes for different types of therapy. His analysis showed that:

93% of cases achieved long-term positive changes after 6 sessions of Hypnotherapy.

72% of subjects achieved long-term positive changes after 22 sessions of Cognitive Behavioural Therapy

and only 38% of people achieved long-term positive changes after 600 sessions of classical psychotherapy.

According to world-renowned research and publications, hypnotherapy is much more effective than the classical methods of treatment. It is especially effective in cases such as:
Anxiety, smoking, obesity, migraines, postoperative recovery, headache and anxiety, burn pain, phantom limb pain, acute and chronic pain, drug addiction, low self-esteem, decreased libido, anger, regeneration after fractures and operations.
