The OCD Workbook: Your Guide to Breaking Free from Obsessive-Compulsive Disorder (3rd Ed). (2010) by Bruce M. Hyman & Cherry Pedrick. Oakland: New Harbinger.

Written with exceptional insight into OCD and solid understanding of scientific evidence on its treatment, this book guides the reader in setting up and following a personal intervention strategy. Possibly the least understood form of OCD is what is called "pure obsessions" or "primarily obsessional OCD" and this workbook has a whole chapter on this topic. There is also a chapter on helping family members understand how to support the person who has OCD.
