With this volume, Advances in Clinical Child Psychology enters its second decade. The goal of the series is to provide clinicians and researchers in the fields of clinical child psychology, child psychiatry, school psychol ogy, and related disciplines with an annual compilation of statements that summarize the new data, concepts, and techniques that advance our ability to help troubled children. Looking forward, the series intends to highlight the emerging developments that will guide our field of inquiry and practice; looking back, the eleven volumes in the series provide an interesting chronicle of changes in our understanding. Each year, scholars are chosen whose recent work is on the leading edge of clinical child psychology and its sibling disciplines, who offer potentially important new theoretical viewpoints, or who are well qualified to discuss topics of emerging importance that are not identified with one particular laboratory. Perhaps more than in any previous vol ume, the authors of the present volume have achieved fully the goals of the series. Volume 11 is a rich source of exciting ideas, important new information, and cogent analysis. The topics of these chapters, moreover, can be seen to represent the important broad themes in clinical child psychology today. The volume begins with two chapters that describe emerging theoretical perspectives.
