Jim Kepner has a useful book on this subject, and he will be presenting on the topic at the upcoming AAGT conference in Cleveland (so audio tapes should be available on his presentation following the conference). Jim's book is titled "Healing Tasks, Psychotherapy with Adult Survivors of Childhood Abuse." Granted, this is not specifically about working with children, but perhaps some help could be gleaned from it. For instance, Kepner posits different developmental stages of healing and assigns specific tasks to each stage; those could prove useful in moving away from revictimization through retelling the story to a more therapeutic process. The book can be ordered from the Analytic Press, Gestalt Institute of Cleveland, or online through Amazon.com.
