Abstract

Cronbach’s alpha is a very commonly used method in biomedical research. Cronbach’s alpha Indicates the extent to which the items in your questionnaire are related to each other, a useful coefficient for assessing the internal consistency of the items. Although this method is commonly used in medical research, the statistical software packages do not have the direct menu-driven operation for Cronbach’s alpha. Hence this paper intends to provide an R function (Cronbach. Alpha) for Cronbach’s alpha analysis.
