Furthermore, after using a more detailed diagnosis referencing the measurement model, it is worth noting the
statistical significance of all parameters, as all coefficient, which measure the relationship between latent and observable variables, are significant at 95% and are all equal contributing to the perception of quality (Table 9),Therefore confirming the validity of the construct. Furthermore, it is noteworthy that the Cronbach’s alpha and Rho’s composite reliability index, have high values (0.925 and 0.928, respectively), assuming that the scale is reliable
measure of the construct (Nunnally, 1978, George and Mallery, 1995; Bentler, 2006).
