The Scientific or Scholarly Rationale: Clinical experience and anecdotal reports have demonstrated EFT to be effective for a wide range of behavioral disorders, including PTSD. However with the exception of several studies demonstrating the efficacy of EFT for the treatment of simple phobias, there have been no formal research studies in this area. It is the intention of this study to extend the phobia studies to the area of PTSD, and to determine what other conditions EFT might be effective in treating. Another intention of this study is to see whether, and to what degree, changes in psychological functioning (as measure by the PAI and TSI) are reflected in physiological markers such as HRV (Heart Rate Variability) and levels of cortisol and DHEA.
