Degrees of freedom 661 624 588 553
NOTES: RMSEA is the Root Mean Squared Error of Approximation (<0.1 is the minimally accepted cut-off; <0.05 is desired); CFI is Comparative Fit Index (>0.9 is the minimally accepted cut-off; >0.95 is desired); TLI is a Tucker-Lewis Index (>0.9 is the minimally accepted cut-off; >0.95 is desired).
