Inner motivation through resolving ambivalences. In this book, the authors present the fundamentals of motivational interviewing (MI) clearly and thoroughly, supported by numerous case studies, along with its development to the present day, application areas, and practical implementation possibilities. Since its inception in the 1980s, MI has found new areas of application: in addition to its successful use in addiction therapy (eating disorders, substance abuse, pathological gambling, etc.), MI can also assist individuals with anxiety disorders or those dealing with chronic illnesses in experiencing their self-efficacy and implementing goal-oriented behaviors. The inner motivation of the client is fostered by exploring and resolving ambivalent attitudes. Since MI primarily focuses on an underlying attitude and a universal approach.
