BACKGROUND: Self-care is increasingly recognized as a key determinant of outcomes in inflammatory bowel disease (IBD), yet its relationship with medication adherence remains inconsistently mapped. This scoping review aimed to explore how self-care-related constructs, including self-efficacy and patient activation are associated with medication adherence. METHODS: A scoping review was conducted according to Joanna Briggs Institute methodology and PRISMA-ScR guidelines. PubMed, Scopus, Web of Science, and CINAHL were searched using terms related to IBD, self-care or self-management, including self-efficacy, patient activation and medication adherence. Primary studies involving adult outpatients were included. Study selection and data charting were performed by two reviewers, with discrepancies resolved through discussion with a third supervisor. RESULTS: The search identified 699 records; after removing 164 duplicates, 535 records were screened. Eleven full texts were assessed, and five studies were included. Evidence was heterogeneous and included interventional and observational designs. Interventions supporting self-management, such as nurse-led counselling and practical tools, were associated with improved adherence. Telemedicine monitoring improved patient activation but not self-efficacy. Observational evidence suggested that higher self-efficacy and lower regimen complexity were associated with better adherence. CONCLUSIONS: Available evidence suggests that self-care-related constructs, particularly self-efficacy and patient activation, may be associated with medication adherence in IBD outpatients. However, the literature remains limited and heterogeneous. Further theory-informed and adequately powered studies are needed.
