This self-paced, text-based independent study is designed for mental health professionals who have already completed EMDR Basic Training and want to strengthen their foundation and fidelity in the work. The course uses Francine Shapiro’s EMDR Therapy: Basic Principles, Protocols, and Procedures (3rd ed.) as its primary text, offering clinicians the chance to revisit the core of EMDR while sharpening their application with complex clients. Participants will review the Adaptive Information Processing (AIP) model, the eight phases of EMDR therapy, and the standard protocol, while exploring how these apply to challenging clinical presentations. Topics include history-taking, preparation, target selection, desensitization, installation, and strategies for working with blocked processing, high-intensity affect, and cognitive interweaves. The study also highlights treatment fidelity, ethical considerations, and adaptations for diverse populations, including dissociation, complex trauma, grief, and medical conditions.
