Initial theoretical CFA model | 36 | 4 | 2074.40 a | 575 | 0.839 | 0.053 | 0.048 (0.046–0.051) |
Final theoretical CFA model | 34 | 4 | 1406.53 b | 508 | 0.896 | 0.048 | 0.039 (0.037–0.042) |
Undifferentiated theoretical CFA model | 34 | 1 | 3384.04 c | 514 | 0.667 | 0.079 | 0.071 (0.069–0.073) |
Note: Significant differences in model fit are represented by comparisons of a with b and b with c. CFI = comparative fit index; SRMR = standardized root mean square residual; RMSEA = root mean square error of approximation.
