Established for fifteen years as the standard work in the field, Melvin Lewis's Child and Adolescent Psychiatry: A Comprehensive Textbook is now in its Fourth Edition. Under the editorial direction of Andres Martin and Fred R. Volkmar two of Dr. Lewis's colleagues at the world-renowned Yale Child Study Center this classic text emphasizes the relationship between basic science and clinical research and integrates scientific principles with the realities of drug interactions. This edition has been reorganized into a more compact, clinically relevant book and completely updated, with two-thirds new contributing authors. The new structure incorporates economics, diversity, and a heavy focus on evidence-based practice. Numerous new chapters include genetics, research methodology and statistics, and the continuum of care and location-specific interventions. A companion Website provides instant access to the complete, fully searchable text."
