Differentiating social phobia and panic disorder: A test of core beliefs

Fears of anxiety symptoms, panic attacks, and negative evaluation as well as assertiveness were examined in 102 patients with a diagnosis of panic disorder alone, social phobia alone, comorbid social phobia and panic disorder, or comorbid social phobia and depressive disorder. The results indicated that social phobia and panic disorder can be differentiated by fears of negative evaluation and by assertiveness, but a substantial overlap between these disorders exists with regard to anxiety sensitivity and catastrophic beliefs about panic attacks. The boundaries between social phobia and panic disorder were especially blurred by the presence of comorbid depression within social phobia. Mood-specific biases in catastrophic thoughts and pessimistic attitudes may account for the findings for depression. Treatment implications are discussed.
