χ2, chi-square; df, degree of freedom; CFI, comparative fit index; TLI, Tucker-Lewis index; SRMR, standardized root-mean-square residual; RMSEA, root-mean-square error of approximation; AIC, Akaike information criterion; BIC, Bayesian information criterion; and △BIC, change in Bayesian information criterion relative to the preceding model. *p < 0.05. The best fitting model was in bold.
