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

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
