RESUMO
The mental health users' movement is a worldwide phenomenon that seeks to resist disempowerment and marginalisation of people living with mental illness. The Latin American Collective Health movement sees the mental health users' movement as an opportunity for power redistribution and for autonomous participation. The present paper aims to analyze the users' movement in Argentina from a Collective Health perspective, by tracing the history of users' movement in the Country. A heterogeneous research team used a qualitative approach to study mental health users' associations in Argentina. The local impact of the Convention on the Rights of Persons with Disabilities and the regulations of Argentina's National Mental Health Law are taken as fundamental milestones. A strong tradition of social activism in Argentina ensured that the mental health care reforms included users' involvement. However, the resulting growth of users' associations after 2006, mainly to promote their participation through institutional channels, has not been followed by a more radical power distribution. Associations dedicated to the self-advocacy include a combination of actors with different motives. Despite the need for users to form alliances with other actors to gain ground, professional power struggles and the historical disempowerment of 'patients' stand as obstacles for users' autonomous participation.
