Childhood anxiety disorders represent one of the most common psychological disorders found among the general population. They can be serious, distressful, and functionally impairing, so much so that there has been an explosion of interest in their treatment, primarily from pharmacological and cognitive-behavioral perspectives. Addressing these perspectives is the Second Edition of Child Anxiety Disorders. Beidel and Alfano pay close attention to new pharmacological and psychological interventions as well as multi-center trials that compare single and combined treatment modalities. Additionally, they include new case studies, sections on stability of childhood fears and the longitudinal course of anxiety disorders, and a new chapter on sleep and anxiety disorders. Written on the cusp of newly published information and studies, Child Anxiety Disorders is relevant, informative, and indispensible.
