Confirmatory factor analysis: goodness-of-fit indices of the tested BPRS-E factor models (n = 240).
| Model | χ2 | CFI | ΔCFI | RMSEA [90% CI] | SRMR |
|---|---|---|---|---|---|
| 21-item, 5-factor (this study model) | 266.53 | 0.78 | 0.05 [0.04, 0.06] | 0.09 | |
| 19-item, 5-factor (this study model) | 189.95 | 0.91 | 0.13 | 0.04 [0.02, 0.05] | 0.07 |
| 15 core items, 4-factor (original model) | 197.08 | 0.70 | 0.08 [0.06, 0.09] | 0.10 | |
| 12 core items, 4-factor (best fitting model) | 63.39 | 0.94 | 0.16 | 0.04 [0.00, 0.06] | 0.06 |
| 15-item, 5-factor (alternative model) | 109.95 | 0.91 | 0.13 | 0.04 [0.02, 0.06] | 0.06 |
χ2, chi square test statistic; CFI, comparative fit index; ΔCFI, changes in the comparative fit index; RMSEA, root mean square error of approximation; SRMR, standardized root mean square residual.
