Obsessive Compulsive Disorder (OCD) consists of intrusive thoughts so terrifying that clients become debilitated in their efforts to neutralize them. The obsessions are intrusive and persistent thoughts, images and urges. The thoughts may concern danger, contamination, or reckless activity. The client fears them, tries to suppress them, but the fear of these thoughts lead to increased frequency, intensity, and duration. Clients develop a catastrophic view of these intrusions. Compulsions are repetitive behaviors, mental acts, or rules. They may involve activities like hand washing, checking, ordering, counting, or repeating words internally. They serve to temporarily eliminate these intrusions, but ultimately lead to more obsessions.
