Some people have the opinion that the results of hypnotherapy are temporary. But the truth is the other way round. The following bar chart shows the effectiveness of different methods of therapy – Psychoanalysis, Behaviour Therapy and Hypnotherapy. You can see in the chart that the results of hypnotherapy have 93% results in merely 6 sessions of therapy which is the highest of the three. The study was conducted by Alfred A. Barrios, PhD and was published in American Health Magazine, Volume 7.
