EMDR FORUM ARCHIVE, 2000
Dose Response Relationship

This study is a follow up study to the original Pitman study which attempted a component analysis of EMDR with 17 multiply traumatized combat veterans. As has been stated on this forum previously, chronic PTSD can not be treated successfully by targeting only a single memory. Combat veterans who have exposure to many traumas need to have their EMDR therapy appropriately designed with enough "doses" of EMDR -- targeted at the multiple memories -- to have a sufficient response to treatment. To clarify how critical this point is, consider this.... Furthermore, back to EMDR, the follow up study compared the participants in the study to an untreated cohort that was outside the study, and so it was not a controlled comparison of treatment in the first place. While we are on this subject, let's not repeat all the criticisms and rebuttals to criticisms of studies that have already been reviewed here in this forum. Readers are referred to the archives to review those prior discussions.
A study of the efficacy of dentistry would obviously have to target more than one rotten tooth, if the whole mouth was full of decay. Any study that purported to test the efficacy of drilling/filling cavities would have to have address a critical amount (and potentially all)-- of the big cavities. If you drilled one tooth, went back five years later, you wouldn't find much difference between those with a mouthful of rotten teeth who had had one "dose" of dentistry compared to those who had had one dose, that is, one tooth addressed. So much for metaphors.
