The beginning chapters briefly describe the changes between the DSM-IV-TR and DSM-5 and emphasize the best of the recent evidence-based CBT assessment and treatment strategies applicable to personality disorders. The book then guides clinicians in each step of the treatment process—from assessment to case conceptualization to selection and implementation of intervention. Case material is used to illustrate this process with the most recent developments from Behavior Therapy, Cognitive Therapy, Schema Therapy, Cognitive Behavioral Analysis System of Psychotherapy, Mindfulness-based therapies, and Dialectic Behavior Therapy.
