Applying confirmatory factor analysis to evaluate the fit of measurement models in education and psychological assessment

Wahyu Widhiarso*, Jiri Kozeny**

Abstract

Confirmatory factor analysis (CFA) was used to verify three measurement models as defined by classical test theory for three scales that represent a wide range of individual attributes and are manifested in various indicators. The congeneric measurement model represents a general true score model whereas the others represent restrictions on congeneric model it. It is assumed that congeneric model will match the characteristics of all of these measures. Accordingly, we hypothesized that the congeneric model will fit to the data. Analysis results suggest that the congeneric measurement model appears to be the best fit for the data. Based on our findings, we recommend that it is important to make a distinction of which measurement model fits to the data before continuing into further analysis. read more
