Causation in Mixed Methods Research: The Meeting of Philosophy, Science, and Practice

Abstract

This article provides a systematic and pluralistic theory of causation that fits the kind of reasoning commonly found in mixed methods research. It encompasses a variety of causal concepts, notions, approaches, and methods. Each instantiation of the theory is like a mosaic, where the image appears when the tiles are appropriately displayed. This means that researchers should carefully construct a causal mosaic for each research study, articulating what is causally relevant given their particular research questions, purposes, contexts, methods, methodologies, paradigms, and resources. Our theory includes 11 propositions that can guide researchers addressing causation.
