Systemic therapy focuses on the social context of mental disorders. Relationship experiences with parents, partners, and other significant individuals influence the development and maintenance of mental disorders. These, in turn, affect family and partnerships. Systemic therapy helps clients and their relatives to change distressing relationship patterns and to further develop existing resources. The book provides an overview of theory and evidence of effectiveness. It describes the therapy process and typical interventions, such as positive reframing, genograms, or family sculptures. It introduces settings with adults, children, and adolescents, as well as individual, couple, and family therapy, along with new approaches in multi-family group therapy and work with complex support systems.
