The consistency was identified by the Goodness of Fit Index (GFI) at 0.992, the Adjusted Goodness of Fit Index (AGFI) at 0.980, and the Root Mean Square Residual (RMR) at 0.00890, and the Root Mean Square Error of Approximation (RMSEA) at 0.0147. Authentic leadership engaged the highest significant effect on psychological capital (0.89), tailed by learning organization (0.30) and organizational commitment (0.11**). Authentic leadership received the indirect effects (0.48**) affecting on learning organization significantly with a total effect (0.78**), through psychological capital and organizational commitment.
