A type of therapy where people with OCD work with a therapist to expose themselves to their obsession that induces the compulsory response and try to resist the compulsion a little by little. Continued exposure to the trigger can lead to a decrease in fear in relation to the trigger and can prevent the need for the compulsive behavior. Essentially this method of therapy gradually exposes the patient to their fears from the thing they are least fearful of working up and as they are exposed to the trigger they work with the therapists to find methods to prevent their compulsory response, and over time habituation allows the person to decrease their response.
