| pubmed-article:2730507 | pubmed:abstractText | The establishment of Panic Disorder (PD) as a distinct diagnostic category stems largely from the conceptualization of panic as a phenomenon qualitatively different from severe levels of anxiety. The current study utilized patients with Generalized Anxiety Disorder (GAD) and Obsessive Compulsive Disorder (OCD) as comparison groups to examine the validity of this conceptualization. Seventeen PD, 29 OCD, and 12 GAD patients completed self-report inventories from which a panic factor was derived. Controlling for level of overall anxiety, the total panic factor was rated significantly higher by the PD group. A cluster of symptoms emerged which differentiated the PD group from the other two groups. The panic items and total score were correlated with total levels of state and trait anxiety but correlations were generally low, accounting for a limited amount of the total variance. Results were interpreted as providing only equivocal support for viewing panic as a separate dimension apart from high levels of general anxiety. A discussion of conceptual issues is presented. | lld:pubmed |
