Abstract
The use of vignettes in research and education is well documented. Documentation of how vignettes are developed and content validity is established, however, are rare. The purpose of this paper is to describe a method for development and establishing content validity of vignettes that can be used to assess student performance and research participant outcomes. This three-phase method was designed to validate seven vignettes for a future research project. Content validity index survey and expert panel interviews were used to inform improvements in validity. Findings showed that clinical vignettes were improved with respect to content relevance (from 0.93 to 0.96) and importance (from 0.68 to 0.93). Developing validated vignettes is essential when used to measure outcomes in education and in research. This three-phase method of vignette development and validation is feasible and effective in improving content validity of vignettes and can be used in other education and research projects.
