Matrix analysis is a methodologic tool used by researchers to systematically enter qualitative data into matrices and to simultaneously perform the complex integrative functions of data analysis and verification of findings. The article focuses on (1) the steps of qualitative data analysis that can be achieved by using matrix analysis, (2) the appropriate conditions for using matrix analysis, (3) the procedure for constructing a matrix, (4) the application of matrix analysis to a research problem that involved refining an emergent theory of the health life-style-change process, and (5) the use of matrix analysis to meet the criteria for trustworthiness of research findings.
