Nearly half of asthma patients in a trial reported non-adherence to medication. This study highlights the importance of accurate self-reporting for adherence interventions.
Area of Science:
- Respiratory Medicine
- Clinical Pharmacy
- Health Psychology
Background:
- Asthma medication adherence is crucial for effective disease management.
- Self-reported adherence is a common but potentially biased assessment method.
- Optimizing compliance interventions requires understanding true adherence rates.
Purpose of the Study:
- To assess self-reported non-adherence in asthma patients within a compliance intervention trial.
- To introduce and evaluate a novel, neutral two-question questionnaire for non-adherence disclosure.
- To explore the extent to which patients disclose non-adherence behavior.
Main Methods:
- A controlled trial involving 244 Danish asthma patients from November 2007 to May 2008.
- Utilized an SMS monitoring and compliance intervention.
- Employed a new approach to self-reported adherence assessment using a two-question survey delivered via the web.
Main Results:
- 43.9% of trial participants reported non-adherence to their prescribed asthma medication.
- This high rate was reported despite participants having previously documented their awareness of the medication regimen.
- The novel questionnaire facilitated the disclosure of non-adherence.
Conclusions:
- A significant proportion of asthma patients (43.9%) are willing to self-report non-adherence.
- The findings underscore the challenges in achieving full medication adherence.
- The developed questionnaire shows promise as a tool for assessing non-adherence in clinical trials.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
