[Reform, responsibilities and networks: about mental health care]

In the context of the Brazilian Psychiatric Reform family members and neighbors of psychiatric patients have been urged to ' participate' in the public policies, mainly as ' social support' although officially considered ' partners' . This reconfiguration of the relationship between State and civil society is reflected in the directive that the services have to take over the responsibility for territories, a change in the logic of supply and demand aimed at stimulating extra-hospital services such as Psychosocial Care Centers, the object of this study, to provide care to the population of a certain geographical area. The purpose of this article is to investigate the psychosocial technologies produced in this specific political, institutional and historical context such as mediation of social changes and conflicts. Among the analyzed materials are the medical records indicating the involvement of the social actors in the social support network.
