Anxiety Sensitivity, Asthma Control, and Quality of Life in Adults with Asthma

Abstract

Objective. The aim of this study was to examine the role of anxiety sensitivity (AS) in terms of asthma control and asthma-related quality of life in a sample of adults with a physician-verified diagnosis of asthma. Methods. Self-report measures assessing psychological and asthma symptoms were mailed to 368 asthma patients from a community allergy and asthma office who had been seen for a physician follow-up visit between 1 January 2009 and 1 January 2010. Participants in the current study were 127 asthma patients (74% female; Mage = 43.4 years, SD = 12.3) who completed and returned the self-report measures. Results. The results indicated that, after controlling for gender, age, negative affect, and number of comorbid medical problems, the physical concerns factor of AS (AS-Physical Concerns) significantly predicted asthma control and all domains of asthma-related quality of life (symptoms, activity limitations, emotional functioning, and environmental stimuli). Conclusions. These findings replicate and extend previous research and indicate that the fear of physical sensations negatively affects both asthma control and quality of life. These findings also suggest that targeting the AS-Physical Concerns may be a novel way to improve asthma control and quality of life.
