Serious mental illness can devastate the lives of people who suffer from it. These persons have a right to be treated according to current knowledge. Psychosocial interventions aim at reintegrating the mentally ill into the community and improving their quality of life. The goal of psychosocial intervention is to help disabled individuals to establish the emotional, social, and intellectual skills needed to live, learn, and work in the community with the least amount of professional support. The refinement of all these approaches has achieved a level where they should be made readily available for every person with severe mental disorders.
