Theoretical background and therapist guidance

People with OCD are trapped in a cycle characterized by repeated obsessions and compulsions. An effective way to break this cycle is exposing individuals to the situations that triggers their obsessions without engaging in compulsions. This facilitates new learning: anxiety declines naturally, feared disasters don’t happen, obsessions reduce, and compulsions are not needed. In this way exposure (facing the feared situation) and response prevention (not doing the compulsion) break the vicious cycle that maintains OCD.

The Why OCD Persists And How ERP Works handout was developed to help clients understand the vicious cycles that keep OCD going and how ERP can help.
