The fourth edition of Concise Guide to Child and Adolescent Psychiatry addresses the essential body of knowledge in the field of child mental health that has been accumulating at a rapid pace since the release of the third edition in 2003. With this acceleration of research has come a greater awareness of the increasing emotional and behavioral problems faced by our youth, refined evaluation practices, and enhanced treatment options, including new medications and evidence-based psychotherapies. Findings that most experts agree are relevant to clinical practice are incorporated into this edition. Designed to be a practical reference tool for psychiatrists, psychiatric residents, medical students, and other mental health, pediatric, and education professionals working in a wide variety of settings, Concise Guide to Child and Adolescent Psychiatry is an important tool for all those working in pediatric mental health.
