Background Due to the high importance of CV assessment and the lack of user-friendly guide, this study was conducted with the aim of providing a tutorial on content validity. Methods This is a tutorial study and the stated information has been collected from reliable sources such as books and similar articles. Results The standardization of a tool in research is a necessary condition for the accuracy of research results. One of the methods of standardizing a questionnaire is to check the content validity (CV). CV means how much a scale measures exactly what it was designed for. CV is checked both qualitatively and quantitatively. In the quantitative method, the content validity ratio (CVR) and the content validity index (CVI) are measured.
