Note. χ2 = Chi-Square test of model fit; df = degrees of freedom. SCR = scaling correction factor for Satorra-Bentler chi-square difference testing; RMSEA = Root Mean-Squared Error of Approximation. CI = Confidence interval. CFI = Comparative Fit Index. TLI = Tucker-Lewis Index. SRMR = standardized root mean square residual; nBIC = Sample size adjusted Bayesian information criteria.
