This guide investigates the clinical application of Mentalization-based Treatment (MBT) as a structured intervention for patients diagnosed with Borderline Personality Disorder. Authors Anthony Bateman and Peter Fonagy, both prominent figures in the field of psychoanalytic research, provide a framework for clinicians to implement MBT in various therapeutic settings. The text synthesizes clinical theory with practical protocols to assist practitioners in fostering the patient's capacity to understand mental states in themselves and others. By focusing on the development of mentalization, the authors argue that clinicians can effectively reduce the symptoms associated with personality pathology.

Clinicians and mental health professionals frequently cite this text as a foundational manual for implementing evidence-based care for personality disorders. Experts highlight the clarity of the clinical instructions, noting that it serves as a necessary companion to the authors' more theoretical academic works.
