The association between anxiety sensitivity and atopy in adult asthmatics

There is growing evidence linking psychological stress to atopic disease, particularly asthma. Anxiety sensitivity, which is the fear of anxiety-related symptoms, may be particularly important in the study of anxiety and atopic disease. The present study examined the association between atopy and anxiety sensitivity in adult asthmatics. A total of 217 asthma patients who had undergone standard pulmonary function and allergen skin prick testing were included. Participants completed the Anxiety Sensitivity Index, Penn State Worry Questionnaire, Type D Personality Scale-16 and Beck Depression Inventory-II on the day of their asthma clinic visit. Total Anxiety Sensitivity Index score was found to be significantly higher in atopic (M = 17.15, SE = .9) versus non-atopic (M = 12.68, SE = 1.5) asthmatics, independent of age, sex, smoking status, asthma severity, asthma duration, and anxiolytic medication use (F = 6.11, p = .014). There was no evidence for a significant association between any of the other questionnaire scores and atopic status.
