This 18-month follow-up study builds on the findings of a randomized experimental evaluation that found qualified support for the short-term effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) in reducing trauma symptoms among adult female survivors of childhood sexual abuse (CSA). The current study provides preliminary evidence that the therapeutic benefits of EMDR for adult female survivors of CSA can be maintained over an 18-month period. Furthermore, there is some support for the suggestion that EMDR did so more efficiently and provided a greater sense of trauma resolution than did routine individual therapy. (Contains 2 tables.)
