Note. AP = adoptive parent, S = state factor. RMSEA = root mean square error of approximation, CFI = comparative fit index, TLI = Tucker-Lewis index, SRMR = standardized root mean residual. The final models selected are in bold. χ 2 represents robust model test statistics, Δχ2 is a function of standard model test statistics in Satorra-Bentler scaled chi-square difference tests.
