Examining the utility of the DESCARTE model for case study research

Abstract

The DESCARTE model aims to guide health care researchers on the design, conduct, and reporting of case studies. The current article critically appraises the utility of the model and provides an example of its application to a multiple case study that examined the effect of MARIO, a social robot, on the resilience of people with dementia. The DESCARTE model is explained, and its strengths and the challenges encountered during its application are discussed. DESCARTE provides a structured framework that promotes quality in case study research by requiring the researcher to articulate philosophical cohesiveness, ethical considerations, reflexivity, and the strategies used during data integration and throughout data analysis. However, the model does not prompt the development of research questions or methods to promote rigor and reflexivity throughout the case study. A task list and additional guiding questions are provided to address these deficits and to improve the utility of the DESCARTE model.
