Exposure and Response Treatment

Exposure treatment purposefully generates anxiety by exposing the patient repeatedly to the feared object or situation, either literally or using imagination and visualization. It uses the most fearful stimulus first. (This differs from the desensitization process because it does not involve relaxation or a gradual approach to the source of anxiety.)

Exposure treatments are usually known as either flooding or graduated exposure :

  • Flooding exposes the person to the anxiety-producing stimulus for as long as 1 – 2 hours.
  • Graduated exposure gives the patient a greater degree of control over the length and frequency of exposures.

In both cases, the patient experiences the anxiety over and over until the stimulating event eventually loses its effect. Combining exposure with standard cognitive therapy may be particularly beneficial. This approach has helped certain patients in most anxiety disorder categories, including post-traumatic stress disorder.
