Advances in Clinical Child Psychology 

The Advances in Clinical Child Psychology series is directed toward the clinicians and researchers in child psychology to alert them to new developments, data, and concepts which advance the ability of these professionals to help troubled children. This volume represents our at- tempt to highlight the emerging issues and breakthroughs that are likely to guide our field of inquiry in the near future. Our goal in selecting authors to contribute to this series is to seek out those whose work is innovative, relevant, and likely to influence future work in clinical child psychology and related fields. Each author is chosen either on the basis of potentially important new information or viewpoints in his or her own work, or because the author is especially well-qualified to discuss a topic that is not restricted to one program of research. In this volume, the impact of disciplines other than psychology on clinical child psychology is well-documented. Rubenstein presents a wide-ranging overview of research on the neurological causes, indica- tors, and reflections of developmental disorders, including a section on the physiological basis of autism. Costello explores how epidemiology is being applied to child psychiatry and offers insights into the growing importance of applying epidemiological methods to clinical practice.
