The first comprehensive history of "psychiatry's bible"-the Diagnostic and Statistical Manual of Mental Disorders.Over the past seventy years, the Diagnostic and Statistical Manual of Mental Disorders, or DSM, has evolved from a virtually unknown and little-used pamphlet to an imposing and comprehensive compendium of mental disorder. Its nearly 300 conditions have become the touchstones for the diagnoses that patients receive, students are taught, researchers study, insurers reimburse, and drug companies promote. Although the manual is portrayed as an authoritative corpus of psychiatric knowledge, it is a product of intense political conflicts, dissension, and factionalism. The manual results from struggles among psychiatric researchers and clinicians, different mental health professions, and a variety of patient, familial, feminist, gay, and veterans' interest groups. The DSM is fundamentally a social document that both reflects and shapes the professional, economic, and cultural forces associated with its use.In DSM, Allan V. Horwitz examines how the manual, known colloquially as "psychiatry's bible," has been at the center of thinking about mental health in the United States since its original publication in 1952.
