Dedicated to the Study of Personality Disorders
The Center for Transference-Focused Psychotherapy

The Personality Disorders Institute (PDI) under the leadership of Otto F. Kernberg, M.D., director, and John F. Clarkin, Ph.D., co-director, is an internationally recognized group of mental health professionals examining the range of personality pathology, including that of borderline personality disorder, and developing empirically supported treatment for these patients. Individuals suffering from personality disorder are characterized by disturbances in self-definition and functioning, and disturbances in their interpersonal relations. Personality disorders are often accompanied by depression, anxiety, self-destructive and suicidal behavior, and serious disturbances in intimate relations, social relations, and work productivity.

The interdisciplinary professionals in the PDI have authored and edited multiple books on psychodynamic theory, practice, techniques, and research findings. These experts have lectured at major conferences concerning personality pathology internationally.

Our team provides training on the treatment of personality pathology both nationally and internationally. We have helped establish TFP training and research sites in Quebec City, Canada; Munich, Germany; Vienna, Austria; London, England; and the Netherlands.

Please Note: Due to new Federal regulations, we are not able to respond to any clinical questions by e-mail. This includes requests for referrals. In most parts of the country, information regarding referrals can be obtained from the local branches of the American Psychiatric Association, the American Psychological Association, and the National Association of Social Workers. They often have lists of therapists who specialize in specific areas of treatment.
