Summary

This observational study aims to understand why some adults with diabetes find it difficult to take their medicines as prescribed. Medication adherence is essential for controlling blood sugar levels and preventing complications, yet many patients face challenges that go beyond personal motivation. The study will examine multiple factors that may influence medication-taking behavior, including patients' understanding of their medicines, beliefs about treatment, family and social support, communication with healthcare providers, and practical issues such as medicine cost, availability, and distance to care. These factors will be analyzed using a structured behavioral framework to better understand how capability, opportunity, and motivation contribute to adherence. By identifying the most important barriers and supports across different levels, this research aims to provide evidence that can guide patient-centered care strategies and improve medication adherence in diabetes management.

Plain Language Summary

Simplified for easier understanding

This study examines why people with diabetes and other chronic diseases sometimes struggle to take their medications as prescribed. Researchers will look at individual, social, and environmental factors — using a behavioral framework called COM-B — to understand the barriers to medication adherence. **You may be eligible if...** - You are 18 or older - You have been diagnosed with a chronic disease (such as diabetes, high blood pressure, cardiovascular disease, or kidney disease) for at least 6 months - You are on long-term prescribed medication - You are willing to complete a questionnaire **You may NOT be eligible if...** - You do not have a chronic condition requiring long-term medication - You are unable to understand or respond to the study questionnaire Talk to your doctor to see if this trial is right for you.

Interventions

OTHERMultilevel Ecological Determinants of Medication Adherence

Assessment of contextual and behavioral determinants associated with medication adherence among adults with diabetes receiving routine clinical care. Determinants include individual-level factors (medication literacy, beliefs about medicines), interpersonal factors (family involvement, social support), healthcare interaction factors (communication quality, regimen complexity), and structural/access-related factors (availability, affordability, distance). These exposures are measured through validated questionnaires and prescription review during a single outpatient encounter. No intervention is assigned as part of the study.
