About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adults aged 18 years or older

Diagnosed with at least one chronic disease (e.g., diabetes mellitus, hypertension, cardiovascular disease, chronic respiratory disease, chronic kidney disease) for a minimum duration of six months

Prescribed long-term medication therapy

Able to understand and respond to the study questionnaire

Disqualifiers

Patients with acute medical conditions requiring immediate care

Individuals with severe cognitive impairment or psychiatric illness that would preclude reliable participation

Patients who are terminally ill

Patients unwilling to participate or provide consent

Trial population

Adult patients receiving routine outpatient care for diabetes at a tertiary-care teaching hospital in North India. Participants are recruited from specialty outpatient clinics managing chronic disease pharmacotherapy. The source population represents individuals undergoing long-term medical management within a structured hospital-based care setting.

Treatments tested in this trial

  • Multilevel Ecological Determinants of Medication Adherence

    Other intervention

    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.

Secondary outcomes

1

Medication Literacy

Medication literacy assessed using the Single Item Literacy Screener (SILS), evaluating the need for assistance in reading medical instructions.

Time frame
Single assessment at enrollment (Day 1)
2

Beliefs About Medicines

Reflective motivation assessed using the Beliefs about Medicines Questionnaire (BMQ-Specific), measuring necessity and concern beliefs regarding prescribed medicines.

Time frame
Single assessment at enrollment (Day 1)
3

Family Involvement in Medication Management

Level of family participation in medication management categorized by degree of responsibility sharing.

Time frame
