  1. SB = Satorra-Bentler; RMSEA = root mean square error of approximate; CI = confidence interval; CFI = comparative fit index; NNFI = non-normed fit index; Initial model, which is defined in Figure 1, has 19 degrees of freedom and the modified model has 16 degrees of freedom; * denotes a SB χ2 statistic that is statistically significant at α = .05
