Evidence for Energy Psychology methods

Evidence for the clinical effectiveness of therapeutic methods derived from energy psychology include:

Thousands of brief case studies
Systematic clinical observation studies
Randomised controlled studies
Brain Scan data
Studies of effects on Heart Rate Variability
Field studies of treatment of PTSD in disaster areas
Audio-visual recordings showing behavioural change
A 14 year audit in South America, incorporating numerous randomised controlled double blind trials demonstrating the superiority of these methods over cognitive behavioural and medication treatments.
Staffordshire University is pioneering the research into the effectiveness of  Emotional Freedom Technique (EFT) or tapping in the UK. http://www.staffs.ac.uk/news/alternative-tapping-technique-good-for-mental-health.jsp
For the current state of Energy Psychology research see the Association of Comprehensive Energy Psychologies (ACEP) website: http://www.energypsych.org/?Research_Landing
Some would say that there is a much greater research evidence base for energy psychology methods than for most other interventions within mental health services.
