EMDR is very good... it is one of the the four treatments approved for PTSD, though EMDR is actually a CBT therapy. As of 2010, the actual statistics for success of the treatment of PTSD stand as follows:
- Exposure Therapy
- Cognitive Therapy
- EMDR
- Stress Inoculation Training
These are the four Tier 1 approved CBT treatments for PTSD, all showing the most efficacy.
Most people when referring to CBT, refer to Cognitive, Exposure and Stress Inoculation, as those three have conclusively shown the most benefit for long term results. EMDR by itself is excellent, but fails for PTSD unless combined with other CBT components to provide the longevity.
LC, what you say about treatment rates for severe cases is absolutely true. Studies that show statistics are useless, as those studies use barely marginal cases, and exclude anyone with severe symptoms, which is PTSD. Studies are useless that have any type of control measure included for treatment outcome.
EMDR however, is only a traumatic memory processing therapy, it is outright proven, and admitted by Shapiro herself, as only traumatic memory processing. You must combine exposure therapy and other stress management components into the equation to provide longevity results, otherwise, everything you process through EMDR is all undone over the course of the following year or two, and suddenly the sufferer is back to square one. These are proven results on current 2010 data by the experts, ie. NIMH, US DOD VA, etc etc.
Even medication now, due thankfully to neuroscience, is starting to be wavered away slowly, as neuroimaging has proved there is no chemical imbalance, or chemical balance to begin with, backing pharmacological companies theoretical basis on the Pax Medica model claimed in the 70's when Prozac came about. It has been the only theory workable, until now after several years of neuroimaging data is showing the same results over and over, being medication should not be a preferred treatment option vs. psychotherapy.
It works on some, but they actually don't know how... and as there is no chemical balance to imbalance like thought, this tends to back why results are so hit and miss with medication types and dosages.
Neuroimaging is now beginning to put a lot of holes in existing theories, which have been accurate as we have known nothing else, but now technology is allowing us to see the brain and its associated areas as provoked under controlled situations.
