In this online course, authors of this curriculum will present an overview of the most important published modifications of EMDR therapy for Complex Trauma (CT) and Dissociative Disorders (DDs), both to highlight the complexity of treating this population and as enticement to obtain further training. We will discuss diagnostic evaluation, discernment of ‘red flags’ in the client’s history/presentation, and the known and potential challenges of applying standard EMDR therapy protocols with clients with CT and DDs. We will briefly describe, with examples, specific techniques in the stabilization phase (Resource Development and Installation, Ego-strengthening, and Enhancing Orientation) and memory processing phase of EMDR therapy (Flash Technique, Memory Fractionation, Wreathing Protocol, Targeting Avoidance Defenses, Constant Installation of Present Orientation and Safety and the Back of the Head Scale). EMDR therapy interventions spanning all 3 stages of complex trauma treatment include Paulsen’s ACT-AS-IF Model, Gonzalez and Mosquera’s Progressive Approach, Kitchur’s Strategic Developmental Model for EMDR, Knipe and Forgash’s Cross Training Model, Knipe’s Loving Eyes Procedure, Fraser’s Dissociative Table
