title: Phobic disorders and anxiety states: how do they differ?
abstract: A review of the clinical literature to date has shown that the nature of the relationship between phobic disorders and anxiety states is still unclear. As a wide range of symptoms are shared by patients with all DSM-III anxiety disorder diagnoses, at this stage there is still a need to investigate the latent dimensions which distinguish the anxiety disorder subtypes. In the present study 176 patients with the DSM-III diagnoses of agoraphobia with panic attacks, social phobia, panic disorder and generalized anxiety disorder completed the Fear Survey Schedule, Fear Questionnaire, Hostility and Direction of Hostility Questionnaire, Maudsley Personality Inventory, and the Hamilton Anxiety and Depression Scales. Group membership was significantly predicted by a discriminant analysis which yielded a Fear Questionnaire agoraphobia function and a social phobia function. The results from discriminant analysis suggests that agoraphobia and anxiety states may be closely related. Classification errors were also determined, providing further evidence with which to refute the claim that agoraphobia has "all or none" characteristics.
