CFI comparative fit index, RMSEA root mean square error of approximation, SRMR standardized root mean square residual, TLI Tucker–Lewis index
CFI and TLI ≥ 0.90 considered acceptable and ≥ 0.95 excellent model fit
RMSEA ≤ 0.8 considered acceptable and ≤ 0.5 good model fit
SRMR ≤ 0.8 considered acceptable model fit
