Describe the implementation and uses of fuzzy cognitive mapping as a constructive method for meeting the unique and rapidly evolving needs of nursing inquiry and practice.Discussion paper.Drawing on published scholarship of cognitive mapping from the fields of ecological management, information technology, economics, organizational behavior and health development, we consider how fuzzy cognitive mapping can contribute to contemporary challenges and aspirations of nursing research.Fuzzy cognitive mapping can generate theory, describe knowledge systems in comparable terms and inform questionnaire design and dialogue. It can help build participant-researcher partnerships, elevate marginalized voices and facilitate intercultural dialogue. As a relatively culturally safe and foundational approach in participatory research, we suggest fuzzy cognitive mapping should be used in settings of transcultural nursing, patient engagement, person and family centered care and research with marginalized populations. Fuzzy cognitive mapping is amenable to rigorous analysis and simultaneously allows for greater participation of stakeholders.In highly complex healthcare contexts, fuzzy cognitive mapping can act as a common language for defining challenges and articulating solutions identified within the nursing discipline.There is a need to reconcile diverse sources of knowledge to meeting the needs of nursing inquiry. Fuzzy cognitive mapping can generate theory, describe knowledge systems, facilitate dialogue and support questionnaire design. In its capacity to engage multiple perspectives in defining problems and identifying solutions, fuzzy cognitive mapping can contribute to advancing nursing research and practice.
