Using Normalization Process Theory as a Practical Tool Across the Life Course of a Qualitative Research Project.

Drawing on work that aimed to understand factors influencing experience of and engagement with the National Health Service (NHS) Health Check Program, this article discusses how Normalization Process Theory was used throughout the life course of a research project. As a relatively new theory, Normalization Process Theory is still being refined and much work undertaken to develop interactive tools and "test" the utility of it. Although there is little published critique of the theory, two main issues have arisen in the literature: (a) difficulties ensuring interpretation of constructs are congruent to the original theory and (b) the intensity of translation work to contextualize the theory to individual settings. These issues are explored in this article by examining the processes undertaken to translate Normalization Process Theory so that it was usable to shape a qualitative research project from design to analysis and interpretation.
