Obsessive Compulsive Disorder has most usually been classed as an anxiety disorder, but there is increasing evidence that perhaps it is schizotypal in nature, ie a belief disorder. Speaking from personal experience as some one who has been diagnosed as schizotypal, the OCD symptoms I have certainly seem consistent with this.
This book suggests that reasoning and logical thinking should be the cornerstone of effective treatment for OCD. It evaluates theoretical, experimental, clinical and treatment aspects of reasoning research, and provides case studies and historical data to back up its assertions. Though the book is clinical in nature and written for clinicians, it is recommended for the lay person and for patients too, simply because there are so few quality books on schizotypal disorder and its relationship to anxiety disorders.
