In many parts of the Western world, interventions for people with mental illness have radically changed in recent decades. In the deinstitutionalized system of today, the role for non-profit organizations is generally characterized by dual goals: political advocacy and service provision. Here, the role and function of the user movement in the Swedish mental health system is examined through a case study of all local branches of the largest non-profit organization within the Swedish mental health field. The empirical material consisted of annual reports from all local branches, and was analysed through two analytical schemes, concerning voice/service and conflict/consensus. The analysis pointed to a user movement that still retained the basic ideas of peer support and mutual aid, but were also increasingly being asked by formal service providers to represent the need of users. A hybrid organization category, a ‘Social Movement Peer Organization’, was identified that where social recreational activities are combined with local political advocacy.
