What is the average time it would take to treat agoraphobia w/o panic disorder?

Varies a lot: Typically people with agoraphobia are also diagnosed with an anxiety disorder, such as panic disorder. If you're avoiding only 1-2 specific situations, you might be diagnosed with a "specific phobia, " or "social phobia" if the avoidance is limited to social situations. These sorts of behavioral and anxiety problems are often improved within a few months, but there is a wide range among patients.

It depends : On the therapist skills and patients motivation to change.
