The use of between-methods triangulation in cancer nursing research: a case study examining information sources for partners of women with breast cancer.

This article describes between-methods triangulation-the combination of research strategies using different methods--and illustrates its use in cancer nursing research by outlining a case study, which identified the information sources for partners of women with breast cancer. By combining both qualitative and quantitative data, the study was found to possess good convergent validity. Between-methods triangulation also provided a more complete picture of the topic of inquiry than that supplied by either method alone. It is a useful strategy for identifying the information sources for partners of women with breast cancer and its use is encouraged in cancer nursing research.
