DC0-3R is the only diagnostic system which supplies at least six subcategories of early feeding behaviour disorders. The system is compatible with DSM IV-R and offers classification on five independent levels of functioning including medical, developmental, social and relational items. Experts of the NoTube team were part of the Task Force Team of the NCCIP (National Center for Clinical Infant Programs) who published the manual in 1994 and came up with the first revision (DC:0-3R) in 2005 (Washington, D.C.: ZERO TO THREE Press). Tube dependency in itself is not a diagnostic category on its own behalf. It can involve posttraumatic aspects, sensory and perceptions issues, anatomical and functional aspects and a range of dysfunctional parental interactions in the feeding situation itself. All these themes are focused on in the diagnostic assessment performed via questionnaire and video analysis and are topics to address in the netCoaching process itself.
