Authored by over 500 internationally acclaimed expert editors and chapter authors from around the world. Completely updated and expanded with almost 40 new chapters. Significantly increased attention to the role of culture in all aspects of evaluation and care. New sections on Digital Mental Health Services and Technologies, Treatment Issues in Specific Populations and Settings, and on Prevention, Systems of Care, and Psychosocial Aspects of Treatment address key advances. This edition is the first comprehensive reference work to cover the entire field of psychiatry in an updateable format, ensuring access to state of the art information. Earlier editions were called “the best current textbook of psychiatry” by the New England Journal of Medicine, and “the gold standard” by the American Journal of Psychiatry. Tasman’s Psychiatry, 5th Edition, builds on the initial vision in prior editions of approaching psychiatric evaluation and care from an integrative bio-psycho-social-cultural perspective. It is designed to be an essential and accessible reference for readers at any level of experience. This editorial approach encompasses the importance of the first encounter between patient and clinician, followed by the complex task of beginning to develop a therapeutic relationship and to develop and implement a treatment plan in collaboration with the patient. The importance of increasing attention to the role of culture and social determinants of mental health is reflected both in specific chapters and in components of many chapters throughout the book, especially in those pertaining to clinical evaluation, the therapeutic alliance, and treatment. The global scope of this edition is reflected throughout the book, including the section on psychiatric disorders where evaluation using both ICD 11 and DSM 5-TR is discussed. Most chapters are authored by experts from at least two different countries or continents, adding a critically important dimension which often is missing in major psychiatric textbooks. Tasman’s Psychiatry, 5th Edition, is an essential reference for all medical professionals and students who need a trusted reference or learning tool for psychiatry, psychology, clinical research, social work, counseling, therapy, and all others.
