Traditionally, obsessive-compulsive disorder has been classified as an anxiety disorder, but there is increasing evidence that it has schizotypal features - in other words it is a belief disorder. This book describes the ways in which reasoning can be applied to OCD for effective treatment regimes.

Are all obsessive disorders best considered as anxiety disorders?

People with strong obsessional doubt and fixed, overvalued obsessional beliefs are often resistant to cognitive-behaviour therapy and difficult to help. In over ten years of clinical practice with people with obsessive-compulsive disorders (OCD), it became clear to Kieron O'Connor, Frederick Aardema and Marie-Claude Pélissier that current cognitive explanations of such disorders are often incomplete.

Beyond Reasonable Doubt presents an innovative approach that brings together reasoning research, philosophy of mind and language, and cognitive therapy to understand OCD. It outlines the development and validation of an inference-based approach to treating OCD, which addresses the inductive and often imaginary narrative leading to obsessional inferences.

Clinical psychologists, psychiatrists and other mental health workers will find this book of great interest. Also included is a complete treatment manual of inferential based therapy (IBA), together with an appendix of supplementary treatment cards for the client that are available online at: www.wileyeurope.com/go/oconnor.

This book describes the ways in which reasoning can be applied to OCD for effective treatment regimes. It moves comprehensively through theoretical, experimental, clinical and treatment aspects of reasoning research, and contains a detailed treatment manual of great value to practitioners, including assessment and treatment protocols and case studies
