Large effectiveness: 1.26

What is Exposure and Response Prevention?

  1. Individuals confront their fears and discontinue their escape response.peter-forster-373964-unsplash

2. With a therapist, the client comes up with a hierarchy of the phobia.

Example: a picture of a plane, followed by being in a car to the airport, followed by being in the airport, etc.

3. Client and therapist approach each fear on the hierarchy while not doing the ritualistic behaviors common to Obsessive Compulsive Disorder, for example.

4. Physiological and psychological distress gradually decreases with exposure to the feared event.
