Hence, the robust maximum likelihood method of estimation was used to estimate the various models . Several fit indices were used, including the Satorra-Bentler scaled chi-square, root mean square error of approximation (RMSEA), standardised root-mean square residual (SRMR),
comparative fit index (CFI), and the goodness of fit index (GFI). Values close to 0.95 for GFI and CFI are considered indicative of good model fit. It is suggested that values close to 0.06 are indicative of acceptable fit for RMSEA, whilst values less than 0.08 are acceptable for SRMR (Hu & Bentler, 1999). In addition, Akaike’s information criterion (AIC) is used in the comparison of competing measurement and structural models with smaller values representing a better fit for the proposed model
