"Confirmatory factor analysis is a special form of factor analysis in which a researcher uses her model as a basis for the final factors. Its purpose is to confirm or refute the researcher's model. To complete a confirmatory factor analysis, a researcher must develop a model and corresponding hypotheses before performing the data analysis. This model relates the variables of interest to one another; the hypotheses should posit how strongly these variables are related. The ultimate goal of a confirmatory factor analysis is to confirm or refute these hypotheses and the model itself by seeing how they conform to the output of the analysis. While confirmatory factor analysis may seem complicated at first, it is actually a fairly straightforward, linear process."
