This book proposes an integrated model of treatment for Personality Disorders (PDs) that goes beyond outdated categorical diagnoses, aiming to treat the general factors underlying the pathology of personality. The authors emphasize the development of metacognitive functions and the integration of procedures and techniques of different psychotherapies. The book addresses the treatment of complex cases that present with multiform psychopathological features, outlining clinical interventions that focus on structures of personal meaning, metacognition and interpersonal processes. In addition, this book: Provides an overview of pre-treatment phase procedures such as assessment interviews Explains the Metacognitive Interpersonal Therapy (MIT) approach and summarizes MIT clinical guidelines Outlines pharmacological treatment for patients with PDs Includes checklists and other useful resources for therapists evaluating their adherence to the treatment method Complex Cases of Personality Disorders: Metacognitive and Interpersonal Therapy is both an insightful reexamining of the theoretical underpinnings of personality disorder treatment and a practical resource for clinicians. "This book fills a gap in available texts on the integrative treatment of severe clinical situations. It presents an updated view on the metacognitive interpersonal therapy model, a fundamental tool for the approach to personality disorders. Theoretical aspects and empirical research findings are combined with examples that illustrate what therapists do concretely in their daily work, so that it is a contribution that enriches Practice Oriented Research. Reading a new book is an adventure, as is treating severe patients. This book allows us to observe, step by step, what that adventure consists of and to arrive at the end greatly enriched." Prof. Héctor Fernández-Álvarez, Fundación Aiglé, Buenos Aires "An exceptionally useful and much needed volume. While there are many books on treating personality disorders, few deal with complex conditions despite them being common. Written by an experienced and thoughtful group of clinicians, the book offers a unique, integrated perspective on an interesting and important clinical problem." John Livesley, Professor Emeritus, Department of Psychiatry, University of British Columbia.
