Foundations of Clinical Psychiatry: Fourth Edition is an introductory text for students of medicine and other health professions, including psychiatric nursing, psychology, social work and occupational therapy, as well as family doctors. This fourth edition emphasizes biological, psychological and social factors in assessing and treating patients, and illustrates this approach with dozens of clinical stories, the integrated use of DSM-5 classifications, and provides further reading suggestions. All twenty-eight chapters have been updated by the five editors in collaboration with their protégés. Chapters on ethics, the effects of trauma and the mental health of indigenous people, and a section on the mental health of refugees also feature.
