Table 6.
Measurement Invariance of PIUQ.
| Model | CFI | TLI | SRMR | RMSEA | 90%CI of RMSEA | ΔCFI | Pass? |
|---|---|---|---|---|---|---|---|
| Configural Invariance | 1.000 | 1.000 | 0.000 | 0.000 | (0.000, 0.000) | Yes | |
| Metric Invariance | 1.000 | 1.000 | 0.014 | 0.000 | (0.000, 0.069) | 0.000 | Yes |
| Scalar Invariance | 0.995 | 0.992 | 0.038 | 0.061 | (0.000, 0.125) | 0.005 | Yes |
Note: Due to the complexity of the model structure of PIUQ scale and the small sample size of the male group, the multigroup model did not converge. Therefore, we packaged the 18 observed variables of PIUQ scale and then conducted multigroup model for this scale.
