The study, "The development of guidelines of treatment and support network and non-specialist treatment programs for eating disorders" was conducted between 2017 and 2019 with the aim of promoting cooperation among medical institutions and local governments to enable patients to receive appropriate treatment for eating disorders at an early stage. The goals of the project were: 1) to clarify the problems of prefectural governments and municipalities in establishing a regional network system of treatment and support for eating disorder patients; 2) to develop tools, such as guidelines, manuals, and materials, for collaboration of multiple psychiatric and medical facilities relevant to eating disorders; 3) to develop early treatments for eating disorders that are feasible to non-specialist doctors; and 4) to establish a model of regional multi-facility cooperation for treatment and support of eating disorders. The organization of the study group consisted of researchers and collaborators with expertise in mental health, psychiatry, and psychosomatic medicine. In this paper, we report on the background and outline of the development of: (1) guidelines for collaboration in the field of psychiatry and in the field of physical medicine, respectively; and (2) early treatment programs for anorexia nervosa and online guided self-help. In the future, it will be necessary to disseminate the deliverables of this research and to verify their effectiveness. The development of more specialized treatment guidelines and materials is also an issue for the future.
