This volume of Advances in Clinical Child Psychology is the third under our editorship and the seventeenth of the series. It continues the tradition of examining a broad range of topics and issues related to the study and treatment of child and adolescent behavior problems. Over the years, the series has served to identify important and exciting new developments in the field and provide scholarly review of current thought and practices. In the openingchapter, Cichetti, Toth, and Lynch examine attachment theory and its implications for psychopathology. They provide exacting commentary on the status of the construct of attachment and its potential role in the development of diverse psychopathologies. Similarly, Richards explores the impact of infant cognitive psychophysiology and its role in normal and abnormal development in the second chapter. Both of these chapters address issues of risk for subsequent psychopathology and are deeply embedded in developmental theory. In Chapter 3/ Nottelmann and Jensen tackle the important issue of comorbidity in psychiatric diagnosis from a developmental perspective.

It is with both pride and sadness that we publish the twentieth and last volume of Advances in Clinical Child Psychology. This series has seen a long and successful run starting under the editorship of Ben Lahey and Alan Kazdin, who passed the baton to us at Volume 14. We are grateful to the many contributors over the years and to the Plenum staff for producing a quality product in a timely manner. This volume covers a diverse array of significant topics. In the open ing chapter, Maughan and Rutter explore the research literatures related to continuity and discontinuity of antisocial behavior from childhood to adulthood. Their review and conceptualization emphasize the significance of hyperactivity and inattention, early-onset conduct problems, low reac tivity to stress, and poor peer relations as potentially influential variables in the persistence of antisocial behavior. Social cognitions, environmental continuities, substance abuse, cumulative chains of life events, and protec tive processes are considered as well."

This volume of Advances in Clinical Child Psychology, which is the second under our editorship and the sixteenth of the series, continues the tradi tion of including a broad range of timely topics on the study and treat ment of children and adolescents. Volume 16 includes contributions per taining to prevention, adolescents, families, cognitive processes, and methodology. The issue of prevention in child clinical psychology is no longer restricted to a few speculative sentences in the future directions part of a discussion section. Prevention research is actually being undertaken, as reflected in two contributions to the volume. Winett and Anderson pro vide a promising framework for the development, evaluation, and dis semination of programs aimed at the prevention of HIV among youth. Lorion, Myers, Bartels, and Dennis address some of the conceptual and methodological issues in preventive intervention research with children. Adolescent development and adjustment is an important area of study in clinical child psychology. Two contributors address key and somewhat related topics, social competence and depression in adoles cence. Inderbitzen critically reviews the assessment methods and meth odologies for social competence and peer relations in adolescence. Reynolds analyzes contemporary issues and perspectives pertaining to adolescent depression."

This nineteenth volume of Advances in Clinical Child Psychology continues our tradition of examining a broad range of topics and issues that charac terizes the continually evolving field of clinical child psychology. Over the years, the series has served to identify important, exciting, and timely new developments in the field and to provide scholarly and in-depth reviews of current thought and practices. The present volume is no exception. In the opening chapter, Sue Campbell explores developmental path ways associated with serious behavior problems in preschool children. Specifically, she notes that about half of preschool children identified with aggression and problems of impulse control persist in their deviance across development. The other half do not. What accounts for these differ ent developmental outcomes? Campbell invokes developmental and fam ily influences as possible sources of these differential outcomes and, in doing so, describes aspects of her own programmatic research program that has greatly enriched our understanding of this complex topic. In a similar vein, Sara Mattis and Tom Ollendick undertake a develop mental analysis of panic in children and adolescents in Chapter 2. In recent years, separation anxiety and/ or experiences in separation from attach ment figures in childhood have been hypothesized as playing a critical role in the development of panic. This chapter presents relevant findings in the areas of childhood temperament and attachment, in addition to experi ences of separation, that might predispose a child to development of panic."

As in past volumes, the current volume of Advances in Clinical Child Psychology strives for a broad range of timely topics on the study and treatment of children, adolescents, and families. Volume 18 includes a new array of contributions covering issues pertaining to treatment, etiol ogy, and psychosocial context. The first two contributions address conduct problems. Using quali tative research methods, Webster-Stratton and Spitzer take a unique look at what it is like to be a parent of a young child with conduct problems as well as what it is like to be a participant in a parent training program. Chamberlain presents research on residential and foster-care treatment for adolescents with conduct disorder. As these chapters well reflect, Webster-Stratton, Spitzer, and Chamberlain are all veterans of programmatic research on treatment of child and adolescent conduct problems. Wills and Filer describe an emerging stress-coping model that has been applied to adolescent substance use and is empirically well justi fied. This model has implications for furthering intervention strategies as well as enhancing our scientific understanding of adolescents and the development of substance abuse. Foster, Martinez, and Kulberg confront the issue that researchers face pertaining to race and ethnicity as it relates to our understanding of peer relations. This chapter addresses some of the measurement and conceptual challenges relative to assessing ethnic variables and relating these to social cognitions of peers, friendship patterns, and peer accep tance."
