CFA = Confirmatory Factor Analysis

CFI = Comparative Fit Index

TLI = Tuker-Lewis Index

RMSEA = Root Mean Square Error of Approximation

WRMR = Weighted Root Mean Square Residual

Hu and Bentler (1999)[58] suggest the following cut off values for good fit, CFI > .95, TLI > .95, RMSEA < .06, and WRMR < .90
