Psychotherapy has developed over the past few decades into a theoretically well-founded and practically proven core area of treatment for addiction disorders. The now third, expanded, and updated edition of the standard work "Psychotherapy of Addiction" is based on the bio-psycho-social model. Experienced medical and psychological therapists describe various methods – from cognitive behavioral therapy to person-centered therapy, as well as body-oriented and imaginative approaches. Comorbid disorders and models of integrated treatment are presented in detail. The volume is intended as a handbook and practical guide for all professionals working in addiction therapy, although the concepts originate primarily from an inpatient setting and often include group therapeutic approaches.
