TST is a model of care for traumatized children that addresses both the individual child’s emotional needs as well as the social environment in which he or she lives. It is about breaking down barriers between service systems, understanding a child’s symptoms in the context of his or her world, and building on a family’s strengths and dreams. It is both a clinical model as well as an organizational model. TST is implemented within an organization to serve as a framework for organizing a multi-disciplinary team of providers from within and outside of an organization to coordinate their interventions. Providers are brought together to address the complex needs of traumatized youth and families using TST as an organizing model concerned with the child’s social environment.
