The synergy of critical realism and case study: a novel approach in nursing research

Critical realism is a framework that explains causations of observable events. It is useful in exploring and explaining complex nursing phenomena. It is grounded in the stratification of reality and the understanding that the world is complex, open, and has interactions that support or cancel each other whether we observe it or not. It can be used as a theoretical foundation of case study approach, an in-depth inquiry that seeks to understand a particular phenomenon within specific settings. This paper introduces the basic concepts of critical realism and how it can inform a qualitative case study methodology. To support this approach, we present a study on caregiving experiences for older people with dementia from culturally and linguistically diverse backgrounds which we believe highlights the value of combining critical realism and case study to inform future nursing research.
