It has been nearly a half-century since the inaugural edition of The Psychiatric Interview in Clinical Practice, and the book's status as a classic was again validated with the second edition a decade ago. This new, third edition maintains the book's reputation with thoroughly updated content that reflects changes brought about by the publication of DSM-5. The book presents the psychiatric interview in the context of the enormous and ongoing progress that has been made in biological and descriptive psychiatry. In addition, the book emphasizes the shift in the social relationship between patient and clinician, recognizing that the therapeutic alliance has become the foundation of all medical treatment efforts and that patients are now better informed and seek active involvement in treatment decisions. The text reflects this growing equality and supports the clinician's efforts to nurture the relationship for optimum therapeutic outcomes. The chapter on the traumatized patient has been completely updated for this edition, and a chapter on the patient with dissociative identity disorder has been added. Clinicians familiar with the previous edition will be pleased that its commonsense, easy–to-use structure has been retained even as its content has been thoroughly revised. The Psychiatric Interview in Clinical Practice will benefit mental health clinicians, both seasoned and in training, ensuring that their skills are current and their knowledge cutting-edge.
