Invivo Driving Desensitization is used to help the client cope with driving phobias as a passenger, driver, and/or pedestrian. After learning relaxation skills, the client and therapist create an "anxiety hierarchy." The hierarchy is a catalogue of anxiety-provoking situations or stimuli arranged in order from least to most distressing. With the therapist's support and assistance, the client proceeds through the anxiety hierarchy. Invivo Driving Desensitization is a therapeutic intervention that reduces driving anxiety through exposure.
