Exposure and response prevention (ERP) therapy is an effective way to
obsessive-compulsive disorder (OCD). With exposure and
response prevention therapy, you repeatedly expose yourself to an obsession,
such as something you fear is contaminated, and deny yourself the ritual
compulsive act, which in this case would be washing your hands.
ERP helps break the link between your obsessive thoughts and
compulsive rituals. This process is repeated every day for several weeks or
months until your anxiety is reduced and you do not feel the need to
perform the compulsive behavior in response to the obsessive thought.
