Throughout her career, Dr. Diamond has conducted clinical research in a number of areas, including 1) Attachment and mentalization in patients with personality disorders and the way they change over the course of psychodynamic treatment; 2) The assessment of mental representations; 3) Separation individuation in individuals and families; 4) The relationship between insecure and maladaptive attachment representations and negative affective style in severely disturbed (borderline and psychotic) adolescents and their families; and 5) The impact of pathological narcissism on the treatment process and outcomes of patients with personality disorders.
A major focus of Dr. Diamond’s research and clinical work has involved exploring how attachment theory and research may illuminate aspects of the therapeutic process and relationship. Her particular focus is on the application of attachment theory and research to the understanding and treatment of individuals, couples, and families. She has authored or co-authored many articles and book chapters on attachment theory and psychoanalysis, mental representation, attachment organization and the therapeutic relationship and process, and attachment and psychopathology. She has also adapted the Adult Attachment Interview (AAI) to explore attachment and mentalization in the patient-therapist relationship in the Patient Therapist Adult Attachment Interview or (PT-AAI). She has participated in many presentations, panels, and workshops on attachment theory and research at The American Psychoanalytic Association, the American Psychiatric Association, and the American Psychological Association.
She is currently a Co-principal Investigator with Eric Fertuck, Ph.D. (Principal investigator) on a study funded by the American Psychoanalytic Association, The Impact of Transference Focused Psychotherapy on Pathological Narcissism: The Validity of Attachment Dimensions as Proxies for Structural Personality Change. This grant is part of an active research protocol at Weill-Cornell, Department of Psychiatry, entitled “Predictors of Change in Borderline Pathology Through Transference-Focused Psychotherapy” (Principal Investigator: John Clarkin, Ph.D.). This study examines the nature of the predictors of different facets of change in BPD patients through TFP, and brings together state-of-the-art psychotherapy, and neurocognitive, attachment, and genetic methodologies in the study of the effects of TFP on borderline pathology. Dr. Diamond also co-leads one of the study supervision groups for TFP research therapists and trains research assistants in administering the Adult Attachment Interview (AAI).
