In obsessive-compulsive disorder, obsessions are repetitive, unwanted and intrusive thoughts, images or urges...was the stove really off? Am I really straight? Did I hit someone while driving? OCD is sometimes called the “doubting disease” (Singer, 2013) because its sufferers tend to doubt the truth or definitiveness of their obsession. These obsessions cause distress and anxiety in the individual who may attempt to suppress the obsession or reassure himself using another thought or action which then becomes compulsive. Because it is impossible to have certainty all of the time, OCD sufferers are stuck in a cycle of obsessions and doubt, compulsions and further doubt. This project’s aim was to provide comprehensive, evidence-based care to patients of the OCD clinic.
