This advanced online course introduces a comprehensive and clinically grounded framework based on concepts developed in Dolores Mosquera’s new book, A Trauma-Informed Relational Approach for Dissociative Parts (TADP). It offers an updated way of understanding and working with clients with complex trauma and dissociative parts. This structured model informs EMDR therapy and highlights action and motivational systems as organizers of experience, reframing dissociative parts as coherent, protective responses that preserve safety, control, and attachment – and guiding effective, relational treatment practices.
