^a p of Close Fit >.05, the null hypothesis is RMSEA <.05.
^b P < .05
^c The 90% confidence interval is .018 to .161
CFI Comparative Fit Index, values > 0.90 indicates a good fit of the model.
RMSEA Root Mean Square Error of Approximation, values < 0.08 indicating acceptable, and < 0.05 good fit of the residuals.
SRMR Standardized Root Mean Residual, values < 0.10 indicating good fit.
Δdf Difference in degrees of freedom from reference model
Δχ² Difference in chi-square from reference model chi square
