Since the publication of the acclaimed second edition of Handbook of Diagnosis and Treatment of DSM-IV Personality Disorders, much has changed in how the personality disorders are understood and treated. However, like its previous editions, this new edition is a hands-on manual of the most current and effective, evidence-based assessment and treatment interventions for these challenging disorders. The beginning chapters describes several cutting-edge trends in the diagnosis, case conceptualization, and treatment of them. Then, specific chapters focus on evidence-based diagnosis and treatment interventions for each of the 10 DSM-5 personality disorders. Emphasized are the most recent developments from Cognitive Behavior Therapies, Dialectical Behavior Therapy, Cognitive Behavior Analysis System of Psychotherapy, Pattern-Focused Psychotherapy, Mindfulness, Schema Therapy, Transference Focused Psychotherapy, and Mentalization-Based Treatment. As in previous editions, extensive case material is used to illustrate key points of diagnosis and treatment.
