Bringing together prominent researchers and practitioners, this authoritative volume describes significant recent advances in understanding and treating anxiety that are grounded in emotional processing theory and the seminal work of Edna Foa. Current etiological perspectives are explained; effective assessment approaches discussed; and important findings presented on the benefits of cognitive-behavioral therapies, pharmacotherapy, and combined treatments. Coverage encompasses the full range of frequently encountered disorders: posttraumatic stress disorder, obsessive/n-/compulsive disorder in children and adults, panic, generalized anxiety, social phobia, and complicated grief. Special topics include the introduction of a new treatment, virtual reality exposure therapy.
