Psychosocial treatments in schizophrenia: a review of the past 20 years.

Pharmacotherapy can improve some of the symptoms of schizophrenia but has limited effect on the social impairments that characterize the disorder and limit functioning and quality of life. Through computerized literature searches and bibliographies of published reports we identified peer reviewed studies of group, family, and individual therapy with schizophrenia and schizoaffective disorder patients. We identified 70 studies: 26 on group therapy, 18 on family therapy, and 11 on individual therapy. Additionally, treatment models were compared in 4 studies and combined in 11 others. Controls were included in 61 and all studies included medication. Benefits in symptoms as well as social and vocational functioning were associated with psychosocial treatments. Family therapy demonstrated the most promising findings and traditional social skills treatment yielded the least robust results. Adjunctive psychosocial treatments augment the benefits of pharmacotherapy and enhance functioning in psychotic disorders. Although these positive results have led to increased enthusiasm about psychosocial treatments for schizophrenia, questions remain about comparative benefits of specific treatment methods and additional benefits of multiple treatments.
