Cardiac Self-Efficacy Mediates the Relationship Between Patient Empowerment and Medication Adherence: A Path Analysis in Patients With Coronary Artery Disease - Empirical Research Quantitative.
Article in Nursing open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimTo examine the mediating role of cardiac self-efficacy in the relationship between patient empowerment and medication adherence among patients with coronary artery disease (CAD) and to identify which empowerment sub-dimensions are most prominent.
designA cross-sectional correlational study.
methodsA convenience sample of adults attending a cardiology clinic completed validated versions of the Coronary Artery Disease Empowerment Scale (CADES), Cardiac Self-Efficacy Scale and Morisky Medication Adherence Scale. Data were analysed using Spearman's correlations, ordinal logistic regression and path analysis with bootstrap mediation testing.
resultsPositive correlations were found among empowerment, self-efficacy and adherence. Regression analysis showed that cardiac self-efficacy predicted adherence, while empowerment did not directly predict adherence. Path analysis confirmed that self-efficacy mediates the empowerment-adherence relationship. The self-determination subscale of empowerment was the strongest predictor of self-efficacy, whereas personal competence was not significant.
conclusionPatient empowerment enhances medication adherence indirectly by building cardiac self-efficacy, primarily through fostering patient autonomy rather than merely providing knowledge. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Nurse-led strategies should target cardiac self-efficacy. Motivational interviewing and autonomy-supportive interventions may be more effective than traditional education. IMPACT: What problem did the study address? The study addressed the gap in understanding the nurse-led interventions that translate patient empowerment into actual medication adherence behaviours. What were the main findings? Self-efficacy acts as the essential bridge between empowerment and adherence and this bridge is built most effectively through self-determination rather than personal competence. Where and on whom will the research have an impact? These results will impact clinical nurses, nurse educators and healthcare professionals involved in cardiac care by highlighting that nurse-led counselling strategies and autonomy-supportive interventions may be more effective for improving medication.
