This paper presents a participant-centred virtue ethics approach, the "Omolúàbí" moral-ethical framework, which moves beyond researcher-centred reflexivity to incorporate participants' moral virtues within a broader research ethics framework. It demonstrates a methodical application of the framework during research with rural "Yorùbá" communities in Northcentral Nigeria through the principles of "continuity"; "adherence to local and national processes"; "adaptation to local ways of being and doing"; and "provision of tangible benefit." After proposing a conceptual approach for participant-centred ethics, the paper explores the tensions and complexities that may occur when attempting to reconcile diverse ethical traditions and provides practical suggestions for researchers who wish to conduct moral and ethical fieldwork in similar contexts. Ultimately, the paper argues for an integration of participants' values and virtues within research ethics in order to affirm diverse ethical and intellectual traditions.
