Treatment for patients with obsessive-compulsive disorder (OCD) has dramatically improved with the innovative use of cognitive-behavioral therapies. Drs. McGinn and Sanderson have developed a comprehensive method of treatment that combines psychoeducational and cognitive restructuring with traditional exposure and response prevention techniques. A detailed session-by-session guide is presented to help clinicians assess and treat OCD with this unique blend of therapies. Using a composite case example, the authors demonstrate exactly how to implement various strategies from the initial interview to the conclusion of treatment.
