It is increasingly recognized that a significant number of individuals with personality disorders can benefit from therapy. In this new edition - based on the treatment of over a hundred patients with antisocial and borderline personality disorders - Kate Davidson demonstrates that clinicians using cognitive therapy can reduce a patient's tendency to deliberately self-harm and to harm others; it also improves their psychological well-being. Case studies and therapeutic techniques are described as well as current evidence from research trials for this group of patients. Cognitive Therapy for Personality Disorders provides a thorough description of how to apply cognitive behavioural therapy to patients who are traditionally regarded as being difficult to treat: those with borderline personality disorders and those with antisocial personality disorders. The book contains detailed descriptions and strategies of how to: formulate a case within the cognitive model of personality disorders overcome problems encountered when treating personality disordered patients understand how therapy may develop over a course of treatment. This clinician's guide to cognitive behavioural therapy in the treatment of borderline and antisocial personality disorder will be essential reading for psychiatrists, clinical and counselling psychologists, therapists, mental health nurses, and students on associated training courses.
