Competency and Role Development in Advanced Nursing Practice Following a Swiss Master’s Cohort Through Education and Early Clinical Practice: Protocol for a Longitudinal Convergent Mixed Methods Study

This study will generate longitudinal evidence on APN competence and role development in a Swiss master's cohort. By developing a conceptual, explanatory model of competence acquisition, role perception, and influencing factors, the study is expected to inform curriculum development, strengthen role clarity, and support the evidence-based implementation of APN roles in the Swiss health care system. Findings will contribute to national and international discussions on APN competency frameworks and professional role development.
