Re: Research Standards (continued)

EMDR research, Dr. Shapiro continues in the 2nd edition of her book, should compare EMDR to other promising methods including exposure, cognitive behavior therapy such as stress innoculation. These should be compared with a non-treatment control when possible. Evaluation should bedone on comparative efficacy, length of treatment, attrition, maintenance and generalization of effect, all issues key to clinical practice. Analysis ofor treatment matching effects on key clinical variables should be conducted.

Component analyses should be conducted on a diagnosed clinical population. If a truncated procedure (dismantled) is conducted against a subclinical poulation, may produce misleading results. The amount of treatment and number of components necessary to bring a subclinical population into the "normal range" may be too small to produce significant observable differences as compared with the treatment's full procedure.

Multiply traumatized vcombat veterans not good subjects for component analyses, given the issues of secondary gain and difficulty in judging the effects of treatment on one or two of many memories. Sample sizes for component analyses should be larger than other studies because a single component of amulticomponent treatment may only produce a partial effect. They should include checks of treatment fidelity, and that appropriate hypotheses are being tested.

It should be noted that the original study, based on EMD, included other procedural elements not described in the article due to space limitations. These augmentations were maintained when the treatment became known as EMDR. The original study was a small sample, and a preliminary study.

Subsequent EMDR studies have been strengthened by the incorporation of more standardizeed diagnostic criteria and symptom measures. Those studies are reviewed in the book as well, and readers are directed to that source for details.
