Several measures were used to assess the model fit: the Chi-square goodness of fit, the ratio of the Chi-square goodness of fit to the degrees of freedom, the root mean square error of approximation (RMSEA), the normed fit index (NFI), and the expected cross-validation index (ECVI).

Also, according to Bentler and Bonett (1980), when the Root Mean Square Error of Approximation is less than.
