Objective: Self-efficacy is a known predictor of patient-reported outcomes in individuals with acquired diseases. With an overall objective of better understanding patient-reported outcomes in adults with congenital heart disease, this study aimed to: (i) assess self-efficacy in adults with congenital heart disease, (ii) explore potential demographic and medical correlates of self-efficacy and (iii) determine whether self-efficacy explains additional variance in patient-reported outcomes above and beyond known predictors. Methods: As part of a large cross-sectional international multi-site study (APPROACH-IS), we enrolled 454 adults (median age 32 years, range: 18–81) with congenital heart disease in two tertiary care centres in Canada and Switzerland. Self-efficacy was measured using the General Self-Efficacy (GSE) scale, which produces a total score ranging from 10 to 40. Variance in the following patient-reported outcomes was assessed: perceived health status, psychological functioning, health behaviours and quality of life. Hierarchical multivariable linear regression analysis was performed. Results: Patients’ mean GSE score was 30.1 ± 3.3 (range: 10–40). Lower GSE was associated with female sex (p = 0.025), not having a job (p = 0.001) and poorer functional class (p = 0.048). GSE positively predicted health status and quality of life, and negatively predicted symptoms of anxiety and depression, with an additional explained variance up to 13.6%. No associations between self-efficacy and health behaviours were found. Conclusions: GSE adds considerably to our understanding of patient-reported outcomes in adults with congenital heart disease. Given that self-efficacy is a modifiable psychosocial factor, it may be an important focus for interventions targeting congenital heart disease patients’ well-being.
