________ is more effective than any other treatment for agoraphobia.

A) Exposure therapy
B) Cognitive therapy
C) Existential therapy
D) Family intervention therapy

Exposure therapy involves gradually exposing the individual to the triggering situations or environments that cause anxiety and panic attacks, while providing coping mechanisms to deal with the anxiety. This is considered the most effective treatment for agoraphobia, as it directly targets the individual's specific phobic responses. Cognitive therapy and family intervention therapy may be helpful as adjunct treatments, but are not as effective on their own for treating agoraphobia. Existential therapy may not be appropriate for treating agoraphobia, as it focuses on broader philosophical questions rather than specific behavioral changes.
