An exploration of analytical tools to conduct a realist synthesis and demonstrate programme theory development: An example from a realist review

Introduction
A realist literature review involves iterative processes, with searches, appraisal and synthesis occurring simultaneously. Whilst this lends itself to theory development, the synthesis process often lacks transparency. This has led to unanticipated challenges for novice realist researchers, particularly PhD candidates.
Methods
The aim of this paper is to contribute to the realist methodological knowledge base by outlining the analytical tools of coding, consolidating and conceptual mapping used within a realist review. Specifically, how these techniques aid the synthesis process and demonstrate the development of valid and evidence informed programme theories.
Results
A worked example is provided to illustrate how; (i) coding techniques using realist logic can evidence a rigorous synthesis process; (ii) the use of consolidating techniques facilitates data management and aids theory development; and (iii) conceptual mapping demonstrates programme theory development.
Conclusions
Recommendations for novice realist researchers include defining and documenting the analytical tools for conducting a rigorous realist synthesis to provide transparency about how valid programme theories were developed. Plus, theory development checks can be built into the structure of the review process.
