________________________________________________________________

Analysis of the goodness of fit values yielded the following results. To indicate a statistically significant fit model, a value of >.90 was used for the comparative fit index and Tucker- Lewis index analyses. Both of these values were below .90; thus, the current model is deemed weak in fitness. The chi-square value of 1162 is considerably high; the CMIN/(degrees of freedom), also referred to as normal chi-square or relative chi-

square, value of 2.35 is <3, which indicates a strong goodness

of fit for the model (Garson, 2005).

Using a goodness of

fit

reference of <.05-.06, the root mean squared approximation value for this model of .91 is therefore, goodness of fit is not supported.

error of deemed high;

For the next and final step in the analysis of the SEM, the structural equation model (Figure 3) was reconfigured by eliminating all independent variables deemed statistically insignificant (with a critical ratio value <1.96). These
