This authoritative book reviews current cognitive-behavioral models of OCD and delineates an innovative, theoretically and empirically grounded approach to assessment and treatment. Leading scientist-practitioner David A. Clark first elaborates and refines existing theories of obsessions and compulsions. He then spells out effective strategies for assessing client needs, developing a clear case formulation, implementing an array of cognitive and behavioral interventions, and troubleshooting potential difficulties. Illustrated with extensive clinical material, the volume is practical and user-friendly. Reproducible appendices feature over a dozen rating scales, client handouts, and homework tasks.

"This very readable and wonderfully detailed volume provides up-to-date and comprehensive coverage of the phenomenology of OCD, as well as the theoretical and research basis for understanding this complicated condition....Especially useful is the detailed presentation of the subtleties of effective cognitive and behavioral interventions."
