Relationship Development Intervention (RDI) is a trademarked proprietary treatment program for autism spectrum disorders (ASD), based on the belief that the development of dynamic intelligence is the key to improving the quality of life for autistic people. The program's core philosophy is that autistic people can participate in authentic emotional relationships if they are exposed to them in a gradual, systematic way. The goal of treatment is to systematically build up the motivation and tools for successfully interacting in social relationships, to correct deficits in this area that are thought to be common to all autistic people.
