Dr. Diana Diamond’s primary clinical interests are in developing psychodynamic approaches to treating patients with personality disorders, with a particular focus on the impact of attachment status and pathological narcissism on the treatment process and outcome. Her major clinical and research interests are in investigating changes in attachment and mentalization in patients with combined borderline and narcissistic pathology over the course of TFP. The author or co-author of four books, she is first author of Treating Pathological Narcissism with Transference Focused Psychotherapy (Guilford Press, 2021) which delineates the model of TFP-N, an adaptation of TFP techniques to reach this difficult group of patients. She has also published and lectured widely on the role of attachment theory and research in understanding personality disorders, assessing mental representation, gender and sexuality, and the application of psychological concepts to understanding narrative and symbolism in cinema. She is the recipient of several awards, including the research award from the American Psychological Association (Division 39), and most recently the Aaron Stern Distinguished Professorship lecture award from Weill Cornell Medical College in recognition of her contributions in further understanding of the etiology, pathology and treatment of narcissism. She serves on the editorial boards of Psychoanalytic Psychology and Psychoanalytic Inquiry, is Co-Vice President of the Margaret S. Mahler Foundation, and is in private practice in individual and couple therapy and psychoanalysis in New York City and Sag Harbor, New York.
