Exposure therapy is a well-researched and very effective method to treat persons with anxiety disorders. Normally, when an individual experiences a high degree of anxiety and distress, s/he seeks to escape from the situation immediately and then avoid that situation again in the future. This natural fear response works well when the fear is accompanied by real danger, but in the case of anxiety disorders, fear and avoidance become “teammates.” Fear and avoidance work together because this avoidance of the feared situation prevents the person from the experiencing the natural process of corrective feedback that would inform the person that while the fear is real, the danger is not.
Exposure therapy seeks to harness this natural process of corrective feedback by encouraging a person to choose not to avoid or escape from his/her anxiety, but rather to intentionally allow the anxiety to remain, knowing that the anxiety is temporary and harmless. When a person remains in the presence of a feared situation or object, a natural process known as “habituation” occurs. Habituation is the phenomenon that occurs when an individual enters cool water in a pool or at the beach and “gets used to it.” To put it simply, we don’t defeat anxiety by avoiding it. We defeat it by outlasting it.
Therefore, during exposure therapy a client and psychologist create a hierarchy of feared situations, and then together decide how to begin and how to proceed up the hierarchy over time, like they are climbing a ladder. The client is always in control of the process and is an active member of his/her treatment team.
