Filling a crucial gap in the clinical literature, this book provides a contemporary view of pathological narcissism and presents an innovative treatment approach. The preeminent authors explore the special challenges of treating patients—with narcissistic traits or narcissistic personality disorder—who retreat from reality into narcissistic grandiosity, thereby compromising their lives and relationships. Assessment procedures and therapeutic strategies have been adapted from transference-focused psychotherapy (TFP), a manualized, evidence-based treatment for borderline personality disorder. Rich case material illustrates how TFP-N enables the clinician to engage patients more deeply in therapy and help them overcome relationship and behavioral problems at different levels of severity. The volume integrates psychodynamic theory and research with findings from social cognition, attachment, and neurobiology.
