This book offers an updated vision of psychoanalytic object relations theory, revealing its application to transference-focused psychotherapy (TFP), a treatment approach derived from, and related to, psychoanalysis. Collecting previously published articles and new material based on empirical studies this volume expands the applications of TFP, illustrating its use in severe personality disorders, disturbances in sexuality and love relations of narcissistic personalities, inpatient hospital treatment, and group settings.
