Addressing epistemologic and practical issues in multimethod research: a procedure for conceptual triangulation.

Although a combination of quantitative and qualitative methods are being used increasingly in nursing research, little practical advice exists about the conduct of such studies. Conceptual triangulation offers one approach to multimethod research, addressing epistemologic and practical issues that have long plagued investigators. Conducting quantitative and qualitative research as parallel studies and using method-specific criteria for rigor provide an alternative to blending methodologic assumptions. Systematic examination of the support for findings guides judgments about model development, and the provision for multiple conceptual models resolves issues about the interpretation of findings.
