Measurement Model Analysis
Structural equation modelling (SEM) was employed as the main statistical technique to analyze
data with confirmatory factor analysis (CFA) using Amos 16. The overall goodness-of-fit was
assessed using fit Indices (X
2
, df, X
2
/df, RMR, IFI, TLI, CFI and RMSEA). The initial
confirmatory factor analysis showed an acceptable overall model fit. The goodness fit indices to
measurement model all values were acceptable the measurement model results are shown in
Table 4.

Summary of Goodness Fit Indices
Type of Measure
Acceptable Level of Fit
Value
Chi-square (χ2)
≤ 3.5 to 0 (perfect fit) and (ρ > .01)
2541.302
Normed Chi-square (χ2)
Value should be greater than1.0 and less than 5.0
2.107
Root-Mean Residual (RMR)
Close to 0 (perfect fit)
.033
Incremental Fit Index ( IFI)
Value should be equal to or greater than 0.90.
.952
Tucker Lewis Index (TLI)
Value should be equal to or greater than 0.90.
.949
Comparative Fit Index (CFI)
Value should be equal to or greater than 0.90.
.953
Root mean square error of
approximation (RMSEA)
Value below 0.10 indicates a good fit and below 0.05 is
deemed a very good fit.
