Unique contributions of anxiety sensitivity to avoidance: a prospective study in adolescents.
Examination of the prospective relation between anxiety sensitivity (AS) and behavioral avoidance is largely absent from the literature. In a longitudinal study of a community sample of 2246 adolescents, participants completed the Anxiety Sensitivity Index (ASI; Reiss, Peterson, Gursky, & McNally (1986). Behaviour Research & Therapy, 24, 1-8), State-Trait Anxiety Inventory (STAI; Spielberger (1983). STAI: Manual for the Stait-Trait Anxiety Inventory. Palo Alto: Consulting Psychologists Press), and the Fear Questionnaire (Marks & Matthews (1979). Behaviour Research & Therapy, 17, 263-267) on an annual basis. To stringently test AS's ability to prospectively predict behavioral avoidance, linear regression was used to test whether AS factors predicted variance in follow-up behavioral avoidance scores after controlling for gender, trait anxiety, panic attacks, and baseline avoidance. Results indicted that the mental and physical subscales of the ASI predicted change in behavioral avoidance. The findings of the study are consistent with the view that AS may serve as a precursor to avoidant behavior and that, regardless of whether or not acute panic has been experienced, those who fear autonomic arousal may be more likely to avoid situations in which those sensations may be present.
