A good way to understand qualitative research in general is to begin with the philosophical bases that drive methodological practices (see first the entry for research). Qualitative researchers assume different epistemological and philosophical stances that influence their work. These include subjectivism, interpretivism, and constructivism. Qualitative work also may be guided by particular theoretical perspectives such as pragmatism; symbolic interaction; and deconstructionism; as well as by postmodernist, poststructuralist, feminist, critical, or participatory/action theories and worldviews. Common values include holism and contextualism.
