The aim of this study was to understand how family members of people with mental disorders conceive the performance of self-help groups (SG). This qualitative study was conducted with eleven family members who participate in a SG of the Maringaense Mental Health Association. Data were collected from April to June 2010 during group meetings, in an adjoining room, by means of semi-structured interviews, which were then subjected to content analysis. Two categories emerged: "The group compensates for deficiencies in care", which points out deficiencies arising from the formal care services and the benefits of SG for family members and, "Idealized care", which reveals the expectations of the family in relation to mental health care. It was concluded that family members would like activities of the SG to be incorporated by mental health care services and for family care to become a part of the care plan.
