Notes. The best fit statistic among the seven models is italicized for each goodness-of-fit statistic. For the χ2/df fit index, ratios of 2.0 or smaller are considered to be good fit. NFI = Normed Fit Index (better fit is indicated by values closer to one). TLI = Tucker-Lewis Index (better fit is indicated by values closer to one). CFI = Comparitive Fit Index (better fit is indicated by values closer to one). PCFI = Parsimony-adjusted CFI (better fit is indicated by values closer to one). PFI = Parsimonious Fit Index (better fit is indicated by values closer to one). RMSEA = Root Mean Square Error of Approximation (better fit is indicated by values closer to zero). Bollen-Stine χ2 is interpreted the same way as the χ2 fit statistic; however, bootstrap analyses of raw data are used to account for nonnormality in the data which results in lower χ2 values.
