Из вашей же ссылки:"Not all agoraphobia is social in nature, however. Some agoraphobics have a fear of open spaces.""Not to be confused with agraphobia, agoraphobia is a condition where the sufferer becomes anxious in environments that are unfamiliar or where he or she perceives that they have little control. Triggers for this anxiety may include wide open spaces, crowds (social anxiety), or traveling (even short distances). Agoraphobia is often, but not always, compounded by a fear of social embarrassment, as the agoraphobic fears the onset of a panic attack and appearing distraught in public. This is also sometimes called 'Social Agoraphobia' which may be a type of social anxiety disorder also sometimes called "social phobia"."
