[Integration of services and practices: the test of experience.]

The authors explore how integration of services takes shape in specific contexts according to data of a research on discourses and practices of mental health workers and consumers of community groups. The analysis aims at understanding how the models prevailing on the level of organization of services impact on one hand, on the rules of work organization of professionals and their concept of problems and interventions and on the other hand, on the climate of organizations and the daily lives of consumers, the relationship between themselves as well as with mental health workers and the place given to consumer's words, projects and wishes. The authors thus examine how organizational models and their implications affect the possibilities offered to consumers and the paths opening or not to improve their lives.
