This book provides a clinical and forensic approach to personality disorders. It references the 10th and 11th editions of the International Classification of Diseases (ICD-10 and ICD-11). It allows the reader to compare categorical (ICD-10) and dimensional (ICD-11) classifications and consider a third—hybrid—classification, as advocated by several scholars. Laying down various diagnostic and therapeutic guidelines, this book will appeal to clinical and forensic psychiatrists, psychologists, residents of psychiatry, and students of medicine and psychology.
