Patients suffering from agoraphobia appear to have less stable home backgrounds, and though a link with precipitating events is not clear it appears that the onset of symptoms coincide with life events.

Family studies reveal that the concordance of agoraphobia in first degree relatives is 19.9%, similar to findings in panic disorder relatives. This supports the view that there is a common fundamental disturbance in the two conditions and that agoraphobia may be a severe form of panic disorder.
