简要总结
This descriptive study aims to examine the relationship between self-efficacy and medication adherence in individuals with coronary artery disease (CAD). The study will be conducted between March and October 2025 at Adıyaman University Training and Research Hospital with a planned sample size of 135 participants. Data will be collected using a Descriptive Information Form, the Self-Efficacy for Managing Chronic Disease Scale, and the Medication Adherence Report Scale (MARS).
详细描述
Coronary artery disease (CAD) remains one of the leading causes of death worldwide. Managing CAD requires long-term treatment adherence and lifestyle changes. Self-efficacy, which reflects an individual's belief in their ability to perform specific health behaviors, plays a key role in disease management. In CAD patients, high levels of self-efficacy have been associated with better treatment adherence, improved symptom management, and successful adoption of healthy behaviors.
This descriptive study is designed to investigate the relationship between self-efficacy and medication adherence in individuals diagnosed with CAD. The study will be carried out at Adıyaman University Training and Research Hospital between March and October 2025. The target population includes patients who have been diagnosed with CAD (e.g., angina pectoris, myocardial infarction) for at least one year and meet the inclusion criteria. Based on a power analysis using G*Power software (effect size f² = 0.15, α = 0.05, power = 0.90), the required sample size is calculated as 112. However, accounting for possible data loss or participant dropout, the final sample size is set at 135.
Data collection tools include:
Descriptive Information Form to assess demographic and clinical characteristics,
The 6-Item Self-Efficacy for Managing Chronic Disease Scale, validated in Turkish by İncirkuş and Özkan Nahcivan (Cronbach's alpha = 0.90),

结局指标
主要结局
Self-efficacy score for chronic disease management
时间窗: At the time of data collection (March 2025 - October 2025)
Self-efficacy levels of patients with coronary artery disease will be measured using the 6-Item Self-Efficacy Scale for Chronic Disease Management. Each item is rated from 1 to 10. The total score ranges from 6 to 60, and higher scores indicate better self-efficacy in chronic disease management.
次要结局
- Medication adherence score(At the time of data collection (March 2025 - October 2025))
