Abstract
Researchers who use a critical perspective analyze the historical, political, economic, social, cultural, and gender factors that impact on the people being studied. Research is regarded as a way to promote social justice. The purpose of this article is to describe why and how a critical perspective was used in designing and implementing research with Aymara women healers in the high plains of Peru. The study is used to demonstrate the usefulness of a critical perspective in global health nursing research to promote social justice.
