There is an urgency to the development of culturally competent care. T
his urgency is due to increasing diversity, increasing disclosure of i
dentities, care delivery moving to homes, and increasing inequity in a
ccess to health care. The development of a knowledge base for cultural
ly competent care is constrained by substantive and methodological iss
ues, such as the limited view of culture as a unit of analysis and lim
itations in designs and methods that could capture the integrative nat
ure of participants' experiences. Therefore, I propose that components
of foundational knowledge in nursing may include, but should not be l
imited to, populations and their cultures; culture-specific nursing ph
enomena; and responses to diversity, marginalization, vulnerability, a
nd transitions. To develop culturally competent knowledge, researchers
, theoreticians, and reviewers are urged to address eight criteria to
ensure rigor and credibility in scholarship: contextuality, relevance,
communication styles, awareness of identity and power differentials,
disclosure, reciprocation, empowerment, and time.
