Anxiety sensitivity has been implicated as a risk factor in the development and maintenance of anxiety and fear-related disorders. Indeed, persons who score high on the anxiety sensitivity index (ASI) are generally more responsive to biological challenge procedures such as CO2-inhalation that directly evoke the feared bodily events. One would expect, therefore, that persons high on anxiety sensitivity should be more conditionable and hence more likely to acquire fears, than persons low on anxiety sensitivity when CO2-enriched air is used as an unconditioned stimulus (UCS). Undergraduates (N = 96), scoring high, medium and low on the ASI received 8 repeated 20-s inhalations of either 20 or 13% CO2-enriched air (UCSs) paired with one of three CSs differing in fear-relevance (snake, heart and flowers). Several autonomic and self-report measures were assessed. Contrary to expectation, electrodermal and cardiac conditioned responses failed to discriminate between ASI groups. Yet, SUDS and severity and frequency of DSM-IV panic symptoms varied reliably as a function of anxiety sensitivity. Overall, the findings suggest that anxiety sensitivity is related to subjective fear-related complaints, but not autonomic responding and conditionability. We discuss clinical and theoretical implications for understanding the place fo anxiety sensitivity in fear onset.
