Advances in Clinical Child Psychology continues to bring to its readers scholarly papers that review and update advances in diverse areas of research with children. The focus on basic and applied work with chil­ dren encompasses several disciplines and professions. This volume, the fifth in the series, continues to expand the range of topics and specialty areas represented by the contributors. In the present volume, contribu­ tions address several different topics related to diagnosis, assessment, and treatment of childhood disorders. Taxonomy, nosology, and assess­ ment of childhood behavioral problems, and social and emotional ad­ justment are discussed. Contributions also address recent advances re­ lated to specific disorders including childhood depression, conduct disorders, and hyperactivity. Factors that impinge on child development and have implications for social adjustment and psychopathology are covered in separate contributions on the effects of divorce and life events as stressors in general. Treatment techniques are also covered in the present volume. A separate contribution on pharmacotherapy de­ tails the latest advances and outstanding issues in that field. Problem­ solving therapy is also covered in a contribution on the cognitive bases of social adjustment in children. As with previous volumes, we would like to express our gratitude to several persons. Foremost are the contributors whose scholarship and expertise contributed fundamentally to this volume, as well as the over­ all series.
