Countertransference, the clinician’s emotional reaction to the patient, is constantly present, strongly influences the therapeutic relationship, but often is overlooked. It is not limited to psychoanalytic treatment but exists in pharmacotherapy, consultation-liaison, forensic, and hospital psychiatric settings. For those psychiatrists who are not familiar with the newer developments in countertransference theory, this book, part of volume 18 in the Review of Psychiatry series edited by John M. Oldham, M.D., and Michelle B. Riba, M.D., will help them become acquainted with how their reactions to patients can be a potential problem but also how it can be extremely useful in treatment and consultation.
