The purpose of the present study was to investigate differences between four anxiety disorder groups with respect to their levels of hostility. Patients with diagnoses of panic disorder, agoraphobia with panic, generalized anxiety disorder and social phobia were compared as regards their performance on the Hostility and Direction of Hostility Questionnaire (HDHQ). Results showed that while the groups did not differ on their extrapunitiveness, there were significant differences on intropunitive scores, with social phobics showing the most self criticism and guilt, followed in order by the agoraphobics with panic, generalized anxiety disorder and panic disorder subjects. Scores on the Anxiety Symptoms and Consequences Scale were used to predict intropunitiveness and extrapunitiveness for each diagnostic group. Results showed that intropunitiveness was related to anxiety symptoms differently for each diagnostic group. Overall, the study indicates that intropunitive hostility may be an important feature of anxiety disorders, especially panic with and without agoraphobia, and that the finding is worth further exploration with longitudinal studies.
