Overall, empirical evidence suggests that (1) individuals with asthma are less likely to engage in physical activity than those without asthma, (2) individuals with asthma are not biased in their subjective reporting of symptoms during aerobic exercise, (3) physical inactivity among individuals with asthma is associated with negative health consequences and increased asthma-related difficulties, and (4) regular aerobic exercise improves asthma symptom management, lung function, and mental health.

The present study evaluated the role of distress tolerance (DT), defined as the ability to tolerate negative emotional states, in the use of four specific emotion regulation strategies (suppression, avoidance, rumination, and reappraisal). Undergraduate psychology students (N = 431, 71.7% female; Mage = 19.80 years, SD= 3.71) completed self-report measures online for course credit. It was hypothesized that, after controlling for the effects of anxiety sensitivity and negative affectivity, DT would be negatively associated with suppression, avoidance, and rumination, and positively associated with reappraisal. Consistent with prediction, low DT significantly predicted greater use of suppression, avoidance, and rumination. However, contrary to prediction, DT did not significantly predict reappraisal. These results suggest that individuals who are unable to withstand negative emotions are more likely to use maladaptive regulation strategies.

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.
