The aim of this paper is to examine the role of qualitative research in the development of the Roy adaptation model. An exploration of the findings from qualitative research using Roy's adaptation model from 1995 to 2005 is compared with the findings and recommendations from a previous review over a 25-year period (1970-1995). The usefulness of qualitative methods in furthering nursing theory is highlighted. Findings from both reviews support the assumptions of the model while generating new information and demonstrating the valuable place of qualitative research in promoting nursing science.
