1) The effectiveness of hypnotherapy is acknowledged for several fields of application by the “Wissenschaftlichen Beirat Psychotherapie” (Scientific Advisory Board for psychotherapy in Germany). Additionally, I’d like to cite Wikipedia:
“In 2003, a meta-analysis of the efficacy of hypnotherapy was published by two researchers from the university of Konstanz in Germany, Flammer and Bongartz. The study examined data on the efficacy of hypnotherapy across the board, though studies included mainly related to psychosomatic illness, test anxiety, smoking cessation and pain control during orthodox medical treatment. Most of the better research studies used traditional-style hypnosis, only a minority (19%) employed Ericksonian hypnosis.
The authors considered a total of 444 studies on hypnotherapy published prior to 2002. By selecting the best quality and most suitable research designs for meta-analysis they narrowed their focus down to 57 controlled trials. These showed that on average hypnotherapy achieved at least 64% success compared to 37% improvement among untreated control groups. (Based on the figures produced by binomial effect size display or BESD.)
According to the authors this was an intentional underestimation. Their professed aim was to discover whether, even under the most skeptical weighing of the evidence, hypnotherapy was still proven effective. They showed conclusively that it was. In fact, their analysis of treatment designs concluded that expansion of the meta-analysis to include non-randomized trials for this data base would also produce reliable results. When all 133 studies deemed suitable in light of this consideration were re-analyzed, providing data for over 6,000 patients, the findings suggest an average improvement in 27% of untreated patients over the term of the studies compared with a 74% success rate among those receiving hypnotherapy. This is a high success rate given the fact that many of the studies measured included the treatment of addictions and medical conditions. The outcome rates for anxiety disorders alone, traditionally hypnotherapy’s strongest application, were higher still (though a precise figure is not cited).(Flammer & Bongartz, “On the efficacy of hypnosis: a meta-analytic study”, Contemporary Hypnosis, 2003, pp179 – 197.)”
2) The effectiveness of EFT has been examined in many studies. In 2012, David Feinstein published an article called “ACUPOINT STIMULATION IN TREATING PSYCHOLOGICAL DISORDERS: EVIDENCE OF EFFICACY” in the journal “Review of General Psychology” of the American Psychological Association. In this article, which is considered to be a milestone towards academic recognition of EFT, Feinstein writes:
“A literature search identified 51 peer-reviewed papers that report or investigate clinical outcomes following the tapping of acupuncture points to address psychological issues. The 18 randomized controlled trials in this sample were critically evaluated for design quality, leading to the conclusion that they consistently demonstrated strong effect sizes and other positive statistical results that far exceed chance after relatively few treatment sessions. Criteria for evidence-based treatments proposed by Division 12 of the American Psychological Association were also applied and found to be met for a number of conditions, including PTSD. “
