Theory and the breadth-and-depth method of analysing large amounts of qualitative data: A research note

This research note builds on a previously published discussion of the ‘breadth-and-depth’ method for working with extensive amounts of secondary qualitative data, to consider the way that theory can be used and developed as part of this method. We illustrate potential deductive, inductive, and abductive logics of the relationship between theory and data that can be pursued using the method, but note that in reality research analysis rarely proceeds along such clear categorical lines. Rather, qualitative researchers are more likely to pursue an approach akin to a retroductive logic and analytic practice, which that the breadth-and-depth method also can accommodate.
