12 sessions are truly the "tipping point" for lasting transformation.
The following statistic will help to explain this finding:
A Survey of Psychotherapy Literature by Alfred A. Barrios, PhD., which was later reprinted in American Health Magazine, revealed the following recovery rates:
Psychoanalysis: 38% recovery after 600 sessions
Behavior Therapy: 72% recovery after 22 sessions
Hypnotherapy: 93% recovery after 6 sessions
While the average presented in this study was 6 sessions for 93% recovery, we have found that most of our clients completely work through an entire issue in less time, approximately 3-4 sessions, which means that with a package of 12 sessions you are able to address approximately 3-4 areas of concern.
We have found that with 12 sessions we are able to access and resolve the root of an issue, which transforms the client in every facet of their lives.
Of course, some topics require more sessions than others, weight loss being one of them. If a client needs to lose 100lbs, that cannot be safely done in only 3-4 sessions and therefore an entire 12 session package (and perhaps an additional package or two) may be used for the various factors affecting the client and their need to lose weight.
