Anxiety sensitivity as a predictor of the development of panic, symptoms, panic attacks, and panic disorder: a prospective study

The purpose of the study was to examine how anxiety sensitivity (AS) acts as a dispositional factor in the development of panic symptoms, panic attacks, and panic disorder. Between 1986 and 1988, data were collected from 505 undergraduates at an urban university. At Time 1, measures used were the ASI to assess AS, the trait scale of the State-Trait Anxiety Inventory (STAI-T) to measure trait anxiety, and self-report questionnaires to measure personal and family history of panic and anxiety symptoms. During the Spring of 1999, 178 of these subjects were re-contacted, and information was gathered on subjects' subsequent development of panic symptoms, panic attacks, panic disorder, and trait anxiety (STAI-T). The ASI was the strongest predictor of the development of panic symptoms and panic attacks. After controlling for trait anxiety, the ASI was not predictive of the development of panic disorder.
