[Psychosocial interventions in severe mental illness: evidence and recommendations: psychoeducation, social skill training and exercise].

This paper summarizes the results of a systematic literature search on three widely used psychosocial interventions for people with severe mental illness: psychoeducation for patients and relatives, social skill training and physical exercise. Based on this evidence, recommendations given in the S3 guidelines on psychosocial therapies in severe mental illness of the German Society for Psychiatry, Psychotherapy and Neurology (DGPPN) will be reported. Areas of future research are identified.
