Recent studies have suggested that anxiety disorders in childhood may be prevented and treated with early intervention programs. It is essential that guidelines are available for health professionals to use in the development of these programs. Following an introductory chapter, chapter 2 explains the rationale for early intervention. Chapter 3 presents an overview of anxiety in children and adolescents and includes the nature, types, and prevalence of anxiety disorders. A discussion of the risk and protective factors for anxiety disorders is included in chapter 4. Chapter 5 reviews existing early intervention programs for anxiety disorders with children and adolescents. This is followed by a discussion of practical issues in chapter 6 and some steps in planning and implementing early intervention programs in chapter 7. (Contains 132 references.) (JDM)
