Effectiveness Studies of Hypnosis
A study of Hypnosis published in The Psychotherapy Journal of the American Psychiatric Association showed the effectiveness of hypnosis. After surveying over 2000 journal articles, Dr. Alfred Barrios came up with the following recovery rates:
Number of Sessions Type of Therapy Recovery Rates
6 Hypnotherapy 93%
22 Behavior Therapy 72%
600 Psychoanalysis 38%
In this article, Dr Barrios pointed out that the average success rate for hypnotherapy was 93% after an average of 6 sessions. This was compared to a 38% success rate after an average of 600 sessions for psychoanalysis and 72% after 22 sessions for behavior therapy.
It is important to remember that these are average numbers and should not be interpreted that any condition can be helped in 6 hypnotherapy sessions. Many would take less time and some may require more.
Some of these studies include:
Hypnosis Most Effective in Smoking Cessation Says Largest Study Ever: 3 Times as Effective as Patch and 15 Times as Effective as Willpower.
Hypnosis is the most effective way of giving up smoking, according to the largest ever scientific comparison of ways of breaking the habit. A meta-analysis, statistically combining results of more than 600 studies of 72,000 people from America and Europe to compare various methods of quitting. On average, hypnosis was over three times as effective as nicotine replacement methods and 15 times as effective as trying to quit alone.

87% Reported Abstinence From Tobacco Use With Hypnosis
A field study of 93 male and 93 female CMHC outpatients examined the facilitation of smoking cessation by using hypnosis. At 3-month follow-up, 86% of the men and 87% of the women reported continued abstinence from the use of tobacco using hypnosis.

81% Reported They Had Stopped Smoking After Hypnosis
Thirty smokers enrolled in an HMO were referred by their primary physician for treatment. Twenty-one patients returned after an initial consultation and received hypnosis for smoking cessation. At the end of treatment, 81% of those patients reported that they had stopped smoking, and 48% reported abstinence at 12 months post-treatment.

Hypnosis Patients Twice As Likely To Remain Smoke-Free After Two Years
Study of 71 smokers showed that after a two-year follow-up, patients that quit with hypnosis were twice as likely to remain smoke-free than those who quit on their own.

90.6% Success Rate for Smoking Cessation Using Hypnosis
Researchers analyzed 18 studies comparing a cognitive behavioral therapy such as relaxation training, guided imagery, self-monitoring, or goal setting with the same therapy supplemented by hypnosis. Those who received the hypnosis lost more weight than 90 percent of those not receiving hypnosis and maintained the weight loss two years after treatment ended.

Hypnosis and Weight Loss
Hypnosis Over 30 Times as Effective for Weight Loss
In a study investigating the effects of hypnosis in weight loss for 60 females, Hypnotherapy group with stress reduction achieved significantly more weight loss than the other two treatments. Randomized, controlled, parallel study of two forms of hypnotherapy (directed at stress reduction or energy intake reduction), vs dietary advice alone in 60 obese patients with obstructive sleep apnea on nasal continuous positive airway pressure treatment.

Two Years Later: Hypnosis Subjects Continued To Lose Significant Weight
109 people completed a behavioral treatment for weight management either with or without the addition of hypnosis. At the end of the 9-week program, both interventions resulted in significant weight reduction. At 8-month and 2-year follow-ups, the hypnosis subjects were found to have continued to lose significant weight, while those in the behavioral-treatment-only group showed little further change.

Weight Loss is Greater Where Hypnosis is Utilized
Research into cognitive-behavioral weight loss treatments established that weight loss is greater where hypnosis is utilized. It was also established that the benefits of hypnosis increased over time.

Hypnosis Showed Significantly Lower Post-Treatment Weights
Two studies compared overweight smoking and non-smoking adult women in an hypnosis-based, weight-loss program. Both achieved significant weight losses and decreases in Body Mass Index. Follow-up study replicated significant weight losses and declines in Body Mass Index. The overt aversion and hypnosis program yielded significantly lower post-treatment weights and a greater average number of pounds lost.
