Dr. Diamond has recently focused on adapting TFP to meet the special challenges of treating patients with narcissistic disorders, including pathological narcissism (PN) and narcissistic personality disorder (NPD), and those with co-occurring borderline and narcissistic pathology (NPD/BPD), a patient group that is both increasingly prevalent and difficult to engage and treat. Pathological Narcissism (PN) and NPD are complex and prevalent mental disorders that involve significant relationship and work-related deficits and have serious implications for social, political, and organizational life. With her colleagues at the Personality Disorders Institute (PDI), she has developed Transference Focused Psychotherapy for pathological narcissism and NPD, or TFP-N, which is described in their recent book, Treating Pathological Narcissism with Transference Focused Psychotherapy (Guilford Press, 2021).
The book provides an overview of the theory, research, and treatment of patients with PN and NPD from a contemporary object relations perspective that integrates psychodynamic, attachment, and neurocognitive perspectives. Transference Focused Psychotherapy for PN and NPD (TFP-N) is designed to meet the specific challenges of working with patients across the spectrum of personality functioning, from higher level to borderline to those with malignant narcissism, the most severe variant of the disorder. While these patients come to therapy with diverse presentations, a common factor is their retreat from reality into an often illusory grandiosity that makes them particularly difficult to engage in treatment. Treating Pathological Narcissism shows the progression of TFP-N as it helps the patient move from the distorted, unintegrated mental representations underlying narcissistic pathology to the more integrated, realistic concept of self and others that characterizes healthier functioning.
Dr. Diamond has also explored the social and political ramifications of pathological and malignant narcissism as it relates to leaders in government, organizations, and social life.
