This is a clinicians' guide to the assessment and treatment of obsessive-compulsive disorder (OCD). It describes the use of cognitive behavioral therapy (CBT), which is evidence-based, in treatment. The brand of CBT detailed here centers around "exposure and response prevention," having to do with controlled exposure to the source of anxiety that leads to a compulsive or obsessive behavior. The book is divided into five chapters. The first, "Description," describes OCD and differentiates it from other problems. Chapter 2, "Theories and Models," reviews pertinent theories. Chapter 3, "Diagnosis and Treatment Indications," is a how-to for assessment of a candidate for treatment. Chapter 4, "Treatment," frames a step-by-step treatment program. Chapter 5, "Case Vignettes," presents four examples of exposures and treatment plans. Annotation ©2015 Ringgold, Inc., Portland, OR (protoview.com)
