In this compact, richly detailed volume, 13 distinguished contributors show how CBT's primary focus of identifying and changing maladaptive patterns of information processing and related behaviors is fully compatible with biological theories and treatments and can be combined with pharmacotherapy to optimize treatment results in clinical practice. In five chapters that illustrate the broadening reach and scope of CBT, these experts discuss research results demonstrating the efficacy of CBT for patients with chronic, severe mental illnesses, as well as for patients with medical illnesses.
