In the last 15 years we have seen a dramatic increase in efforts to develop and evaluate new psychosocial treatments for a variety of child and adolescent psychiatric disorders. The editors of this volume address a serious need, the development, they say, of "a comprehensive document that recapitulates ongoing research of the psychosocial treatments for children and adolescents that examines, in detail, several therapeutic approaches for different disorders and that, at the same time, can be used for teaching, research, and clinical practice." This book is indeed such a document. Most of the chapters are reviews of research projects funded by the National Institute of Mental Health on specific psychosocial interventions.
