In the EMDR approach to psychotherapy, each patient is approached in an individualized manner. This presentation will clarify core elements of history taking and AIP informed case formulation including pacing, methods and depth of history taking and simple ways to screen for factors that complicate EMDR therapy. Participants will consider best practices for responding to Phase one case vignettes including: pacing history taking, prior adverse EMDR therapy experiences, and fears of facing a traumatic past. Forms for organizing patient history, triggers, symptoms and concerns will be presented and reviewed. Sample target sequences will be presented for common treatment plans.
