After an introduction to the fundamentals and the general therapeutic concept, specific therapeutic approaches are described—both school-specific and cross-school methods and techniques. This includes work with emotions, personality parts, the Felt Sense, imaginations and dreams, addressing motivation issues, as well as the existential perspective, pre-therapy, the inclusion of the body, creative media, and constellations. Furthermore, the psychotherapeutic work with children and adolescents, families, couples, and groups is presented, along with the handling of individuals experiencing crises, trauma-related disorders, addiction issues, eating disorders, sexual problems, depression, anxiety, and personality disorders. The second edition has been updated and revised in content, with particular expansion in the sections on methods and techniques.
