Depressive disorders are among the most common types of psychopathology in the United States.  Adolescent-onset depressive disorders represent particularly insidious conditions because of their strong association with chronic and recurrent emotional problems in adulthood. This handbook offers authoritative reviews of research on the nature, causes, and treatments for depression in adolescents. It covers the breadth of this research, focusing on etiology, predictors, and the interplay of biological, psychological, and social factors in adolescent depression. Highlighting both recent studies on treatment of adolescent depression and the prevention programs directed at high-risk youth, the book also covers assessment, diagnosis, and epidemiology, and related and comorbid conditions. Handbook of Depression in Adolescents is an invaluable and comprehensive resource for students and practitioners alike.
