Yet only recently has the study of youth benefited from advances in both clinical and scientific research. Advances in the social and biological sciences, the emergence of disciplines and subdisciplines that focus exclusively on childhood and adolescence, and greater appre- ciation of the impact of such influences as the family, peers, and school have helped accelerate research on developmental psychopathology. Apart from interest in the study of child development and adjustment for its own sake, the need to address clinical problems of adulthood naturally draws one to investigate precursors in childhood and adolescence. Within a relatively brief period, the study of psychopathology among children and adolescents has proliferated considerably. Several different professional journals, annual book series, and handbooks devoted entirely to the study of children and adolescents and their adjustment document the proliferation of work in the field. Nevertheless, there is a paucity of re- source material that presents information in an authoritative, system- atic, and disseminable fashion. There is a need within the field to convey the latest developments and to represent different disciplines, concep- tual views, and approaches to the topics of childhood and adolescent adjustment and maladjustment. The Sage Series Developmental Clinical Psychology and Psychiatry is designed to serve uniquely several needs of the field. The series encom- passes individual monographs prepared by experts in the fields of clinical child psychology, child psychiatry, child development, and related dis- ciplines. The primary focus is on developmental psychopathology, which in this volume refers here to the diagnosis, assessment, treatment, and prevention of problems that arise in the period from infancy through adolescence. A working assumption of the Series is that understanding, Vll Vlll ATTENTION DEFICITS AND HYPERACTIVITY identifying, and treating problems of youth must draw on multiple disciplines and diverse views within a given discipline. The task for individual contributors is to present the latest theory and research on various topics including specific types of dysfunction, diag- nostic and treatment approaches, and special problem areas that affect adjustment. Core topics within clinical work are addressed by the series. Authors are asked to bridge potential theory, research, and clinical practice and to outline the current status and future directions. The goals of the series and the tasks presented to individual contributors are demanding. We have been extremely fortunate in recruiting leaders in the fields who have been able to translate their recognized scholarship and expertise into highly readable works on contemporary topics. The present monograph, prepared by Dr. Stephen Hinshaw, focuses on attention deficits and hyperactivity in children. The topic has received a great deal of attention in research and is commonly encountered by parents, teachers, and therapists in everyday life. In many ways, atten- tion deficits and hyperactivity serve as a showcase for many advances as well as challenges before researchers and practitioners in the mental health professions. In this book, Dr. Hinshaw masterfully presents advan- ces and challenges in diverse areas including diagnosis, assessment, etiol- ogy, and intervention. The developmental course of the attention deficits is traced, with an effort to identify promising and needed interventions to improve current practice. The book is enriched by the fact that the author's own work has played an important role in elaborating key features of attention deficits. Overall, the monograph provides a com- prehensive yet concise presentation of attention deficits, current advan- ces, and sources of controversy that currently guide both clinical re- search and practice. Alan E. Kazdin, Ph.D. PREFACE The amount of literature that has been published in recent years regard- ing the constellation of behavioral and cognitive problems commonly known as hyperactivity, attention deficit disorder, or attention-deficit hyperactivity disorder (ADHD) is nothing short of staggering. Supple- menting the countless journal articles that appear each year, a number of books on the topic have appeared within the past decade, including a provocative monograph (Conners & Wells, 1986) in this very series on Developmental Clinical Psychology and Psychiatry. Attempting to synthesize findings from this vast and often confusing array of infor- mation is both daunting and challenging. Furthermore, misinformation abounds in the field. Public and even professional understanding of children with clinically significant atten- tion problems and overactivity is limited by outdated notions, subopti- mal assessment strategies, nonreplicated scientific findings, and pervasive tendencies to pursue narrow, unidimensional perspectives in both scholar- ship and intervention. Regarding the latter point, such prior terms as minimal brain dysfunction for many years ascribed causation exclusive- ly to neural mechanisms, whereas other paradigms looked solely toward deviant parent-child interaction as the key etiologic factor. Notions of com- plex causal pathways in which psychobiologic risk factors, problematic family functioning, and wider system influences might combine to shape problems in attention regulation, activity level modulation, and response inhibition have been slow to gain acceptance. My chief goals for this book are as follows: (a) to provide sufficient background information regarding basic clinical, conceptual, diagnos- tic, etiologic, and treatment-related issues so that readers are conversant with major themes; and (b) to illuminate and critically evaluate several key debates and core questions that have confronted the field for many years and that still merit close consideration. Such questions include the IX
