Area of Science:

• Behavioral Science
• Respiratory Medicine
• Health Psychology

Background:

• Asthma affects millions, with 70% non-adherence to treatment despite available management strategies.
• Current one-size-fits-all approaches are insufficient due to limited resources for personalized care.
• A feasible tool is needed to identify individual psychological and behavioral adherence barriers.

Purpose of the Study:

• To apply the Capability, Opportunity, and Motivation-Behavior (COM-B) model questionnaire to identify patient-specific adherence barriers.
• To explore psychological and behavioral barriers related to treatment adherence in diverse asthma populations.
• To investigate associations between COM-B responses and asthma phenotypes.

Main Methods:

• A 20-minute iPad-based questionnaire assessing psychological and behavioral barriers using the COM-B model.
• Data collection at a single visit in an asthma clinic setting.
• Routine collection of participant demographics, asthma characteristics, control, quality of life, and medication regimens.

Main Results:

• Study is currently underway.
• Results are anticipated by early 2023.

Conclusions:

• The COM-B questionnaire offers a theory-based, accessible tool for identifying asthma adherence barriers.
• Findings will inform healthcare professionals about behavioral barriers, enabling individualized interventions.
• The study aims to improve medication adherence and address psychological needs in asthma patients.
