COGNITIVE BEHAVIORAL THERAPY (CBT) is the fastest-growing form of psychotherapy and the most widely applied worldwide, as it has proven its effectiveness in a wide variety of mental disorders. This book presents the basic theoretical framework of CBT as well as all the necessary elements for its effective clinical practice. It helps therapists develop their understanding of their case, plan an effective therapeutic process, enrich their techniques, and directly address any difficulties. "Judith Beck's book titled 'Introduction to Cognitive Therapy,' which was published in Greek in 2004, was an extremely successful book. It was translated into dozens of languages and became the basic manual for every cognitive behavioral therapist—from the inexperienced to the experienced therapist—as well as for every training program in CBT in Greece and around the world. The tremendous progress of CBT over the past 15 years or so led the author to revise her book. The content of the chapters has been rewritten to a great extent, and three new chapters have been added. Additionally, Judith Beck personalizes the therapeutic process, as she now speaks as a therapist-supervisor in the first person, making the reading experience even more immediate as she addresses the reader-therapist in the second person. For these and many other reasons, the book 'Introduction to Cognitive Behavioral Therapy' becomes even better than its very good previous edition." GRIGORIS SIMOS (Psychiatrist, Associate Professor.
