Recently developed psychosocial treatments for anxiety disorders reflect the systematic influence of scientifically generated knowledge, and these new treatments yield strong results. Research in such areas as information processing, cognition, behavioral avoidance, and the physiological components of anxious arousal has increased our knowledge of mediators that cause and maintain anxiety disorders.The development of these new clinical tools is timely, as epidemiological studies now show that up to 25% of people will experience at least one anxiety disorder in their lifetime. Meanwhile, mental health care providers are increasingly pressured to limit the number of sessions and use demonstrably effective treatments.In this book, the authors review psychosocial treatments for anxiety disorders, focusing on the scientific basis and demonstrated outcomes of the treatments. Cognitive behavioral therapies are highlighted, as they have been the most frequently investigated approaches to treating anxiety disorders. Individual chapters feature specific phobias: social phobia, panic disorder, and generalized anxiety disorder. The book is rich in clinical material and integrates science and clinical practice in an effort to help practitioners to improve the effectiveness of their work with anxious clients.
