The comparative fit index (CFI) analyzes the model fit by examining the discrepancy between the data and the hypothesized model, while adjusting for the issues of sample size inherent in the chi-squared test of model fit, [21] and the normed fit index. [37] CFI values range from 0 to 1, with larger values indicating better fit.
