A cross-sectional study published in the Journal of Cardiac Surgery assessed the concordance between patient-reported and caregiver-perceived cardiac self-efficacy in individuals undergoing coronary artery bypass grafting (CABG). A total of 246 patients and their caregivers were enrolled using sequential sampling. 

Data were collected using three structured questionnaires, and statistical analyses included t-tests, one-way analysis of variance, Mann–Whitney U, Kruskal–Wallis, and regression modeling to evaluate relationships between variables. The study aimed to determine agreement levels and identify factors associated with differences in perception.

Overall, 67.1% of participants demonstrated a high level of perceived cardiac self-efficacy. Patient-reported self-efficacy scores showed a weak inverse correlation with disease duration (r=−0.162; p=0.011) and cognitive impairment (r=−0.428; p<0.001). Positive correlations were observed with personal control (r=0.159; p=0.013), treatment control (r=0.151; p=0.018), and disease understanding (r=0.146; p=0.022). 

A strong positive correlation was noted between patient-reported self-efficacy and caregiver perception (r=0.874; p<0.001). Differences between patient and caregiver perceptions were statistically significant only across patient education levels (p=0.033). Additionally, increasing cognitive impairment was associated with reduced disparity between patient and caregiver assessments (β=−0.079; p=0.040).

Patient and caregiver perceptions of cardiac self-efficacy were generally aligned but influenced by cognitive and educational factors. These findings highlight variability in perception across subgroups.
