The role of traumatic stress in shaping early development and the issue that exposure to complex interpersonal trauma is qualitatively distinct from acute trauma in both experience and effect cannot be understated. Traumatized children need a flexible approach to intervention. ARC has been developed in response to this challenges as an intervention framework designed to address the array of developmental vulnerabilities experienced by the complexly traumatized child by building or restoring developmental competencies, identifying and enhancing internal, familial, and systemic resources, and providing a foundation for continued growth.
