Note: χ2 = Model chi-square statistic. df = Degrees of freedom. CFI = Comparative fit Index. TLI = Tucker-Lewis index. RMSEA = Root mean square error of approximation. SRMR = Standardized root mean squared residual. AIC = Akaike information criterion. BIC = Bayesian information criterion. * p < 0.001.
