EMDR Phase 2 is often where clinicians slow down and ask more careful questions. After history taking and treatment planning in Phase 1, the focus shifts to readiness, stabilization, and safety. This intermediate-level continuing education online course examines how to assess dissociation, evaluate regulation capacity in real time, and determine whether dual attention remains intact under mild activation. The course will address how to modify stabilization and resourcing when clients cannot generate visual imagery, including aphantasia, and how preparation may need to be structured differently for neurodevelopmental differences. Designed for licensed clinicians who have completed formal EMDR training, this on-demand webinar reviews current research on EMDR mechanisms, intolerance of calm, and processing difficulties, while applying those findings to clinical scenarios such as loss of dual attention, elevated DES-II scores, recurrent SUD rebound between sessions, and difficulty generalizing gains. The emphasis is practical: extending preparation when indicated and selecting strategies based on observable presentation rather than protocol habit.
