This introductory packet provides an introduction to anxiety problems, framing the discussion within the classification scheme developed by the American Pediatric Association. The variations in degree of problem are discussed with respect to interventions that range from environmental accommodations to behavioral strategies to medication. The packet is divided into six sections. Section 1 highlights the classification of anxiety problems, and specifically the importance of keeping the environment in perspective as a cause of commonly identified psychosocial problems. Sections 2 and 3 provide a discussion of the broad continuum of anxiety problems, as well as a quick overview of some basic resources. Section 4 presents interventions for anxiety problems, including accommodations to reduce anxiety, behavior management and self-instruction, and medication. Section 5 presents additional resource aids. Section 6 concludes with a discussion on keeping anxiety problems in broad perspective. For further information, a set of references, a list of agencies and Web sites, and other resources are included. (GCP)
