There have been a number of exciting advances in the area of behavioral pediatrics this past year. Perhaps the most important is the increased methodological sophistication of the studies that are being published. For example, studies with prospective random assignment to alternative treatment groups have documented the efficacy of programs for treating sibling rivalry, bulimia nervosa, injection phobia, headaches, Tourette syndrome, tics, and attention deficit hyperactivity disorder (ADHD). Simple treatment procedures have been described for the management of thumbsucking and hair pulling, and injection phobia. Substantive analyses have been published in the areas of encopresis and ADHD. The breadth of the topics examined and the increased sophisitication of the research designs represent substantial gains in the area of behavioral pediatrics.
