Emotion regulation among adults with asthma: Links with short-acting inhaler medication overuse and utilization of acute medical care.

Objective: Existing research suggests that emotion plays an important role in airway inflammation and asthma symptom control. The objective of this study was to determine whether difficulties regulating emotion were associated with overuse of short-acting inhaled medications and acute medical care usage in adults with asthma.

Methods: The sample included 401 adults with asthma recruited from an online panel of adults with chronic respiratory disease. Sequential binary logistic regression models were used to examine the associations of emotion regulation with short-acting inhaled medication use and acute medical care use, controlling for patient characteristics and comorbid mental health conditions.

Results: Greater difficulties with emotion regulation were significantly associated with greater odds of short-acting inhaler medication overuse (p < 0.001), emergency department visits (p < 0.001), and hospitalizations (p = 0.001).

Conclusions: Emotion dysregulation may play an important role in asthma management. Evidence-based interventions to reduce difficulties in emotion regulation may help improve problematic patterns of short-acting medication overuse and acute service use. The current findings should be interpreted in the context of several limitations, including the use of self-report measures. Future research should use electronic medical records or metered dose inhalers to objectively assess short-acting inhaler overuse and acute medical care use.
