All over the world, traumatizing events and conditions (war, domestic terrorism, criminal violence, natural disasters, poverty, diseases, accidents and more) are extensive and ongoing. Massive unmet needs for trauma relief exist. EMDR-based Early Intervention (EMDR-EI) protocols allow much larger numbers of traumatized people to receive effective services. Therefore EMDR-EI offers an exciting opportunity to meet these needs, both among well-resourced and disadvantaged populations.
