Qualitative Comparative Analysis and Implementation Research: An Introduction


by Laura Damschroder, MPH ; Edward Miech, EdD
Seminar date: 1/7/2016

Description: Qualitative Comparative Analysis (QCA) is a numerical, case-oriented approach for examining complex causality in implementation. QCA helps determine necessary and sufficient conditions for implementation success and allows for equifinality (i.e., when multiple pathways lead to the same outcome). QCA uses numbers to represent “membership” in a defined group or set, and draws upon applied set theory and Boolean algebra to reveal direct, explicit connections between specific combinations of conditions and implementation outcomes. This presentation will provide an introduction to QCA using examples from several recent VA implementation evaluations. Intended audience: Participants in the VA Implementation Research Group and others interested in implementation research and/or data analysis methods (VA or non-VA).
