Résumé

To discuss the multi-centre qualitative methodology as a unique design, articulate its guiding paradigm/theoretical perspectives, and highlight its methodological and methodical issues. A secondary objective is to generate further scholarly discourse regarding the multi-centre approach within the broader qualitative research tradition. Methodological discussion. Rather than an emphasis on only experiences, the multi-centre approach is presented as a unique design which also focuses on uncovering why a phenomenon or problem exists and perceptions regarding the phenomenon/problem. With its focus on capturing multiple subjective realities, the multi-centre qualitative design is arguably underpinned by pragmatist constructivism which offers a robust framework for researching phenomenon in a way that is both theoretically informed and practically relevant. Methodologically, the multi-centre qualitative research design emphasises a problem-centred enquiry, collaborative approach and rigorous study protocols, systematic site selection, contextual immersion and sensitivity and methodical flexibility. With the rapidly evolving nursing and global health landscape, the multi-centre design lends itself to exploring and capturing perceptions on a larger scale compared to single site studies. Careful planning, availability of adequate resources, rigorous protocols and quality assurance plans are critical to ensuring its success. The multi-centre approach offers the possibility of undertaking the same study across multiple settings/locations which has the potential to improve representation and strengthen transferability. This methodological discussion offers clarity regarding the use of the multi-centre approach and offering strategies for its subsequent uptake in nursing and healthcare research. Not applicable. No patient or public contribution.
