Borderline Personality disorder is a severe personality dysfunction characterized by behavioural features such as impulsivity, identity disturbance, suicidal behaviour, emptiness, and intense and unstable relationships. Approximately 2% of the population are thought to meet the criteria for BPD. The authors of this volume - Anthony Bateman and Peter Fonagy - have developed a psychoanalytically oriented treatment to BPD known as mentalization treatment. With randomised controlled trials having shown this method to be effective, this book presents the first account of mentalization treatment for BPD. The first section gives an overview of BPD, including discussion of nosology, epidemiology, natural history, and psychosocial aetiology. It additionally summarises the present state of our research knowledge about effective psychotherapeutic treatments and use of medication. The second section outlines the authors' theoretical approach and contrasts it with other well known methods, including DBT, CAT, and CBT. In the extensive final section, the authors outline their clinical approach starting with how treatment is organised. A detailed account of the transferable features of the model is provided along with the main strategies and techniques of treatment. Numerous clinical examples are given to illustrate the core techniques and detailed information provided about how to apply aspects of the mentalization based treatment approach in everyday practice. Aimed at mental health professionals, along with counsellors, psychotherapists, and psychoanalysts, the book will be a valuable tool, providing an effective means of treating those suffering from Borderline Personality Disorder.
