CFA of the SF-MPQ-2-CN subscales
| SF-MPQ-2-CN subscales | GFI | RMSEA | NFI | RFI | RMR | Chi-square | Degrees of freedom | p-Value |
|---|---|---|---|---|---|---|---|---|
| Continuous | 0.967 | 0.07 | 0.967 | 0.995 | 0.182 | 15.373 | 9 | 0.081 |
| Intermittent | 0.957 | 0.088 | 0.97 | 0.951 | 0.149 | 18.940 | 9 | 0.026 |
| Neuropathic | 0.975 | 0.042 | 0.982 | 0.969 | 0.131 | 11.244 | 9 | 0.259 |
| Affective | 0.952 | 0.213 | 0.965 | 0.895 | 0.023 | 14.991 | 2 | 0.001 |
Notes: Acceptable fit of the CFA analysis solutions was evaluated based on both GFI and NFI ≥0.90 was considered acceptable; SRMR ≤0.08 was considered acceptable.
Abbreviations: CFA, confirmatory factor analysis; GFI, goodness of fit index; NFI, normed fit index; RFI, relative fit index; RMSEA, root-mean-square error of approximation; RMR, root-mean-square residual; SF-MPQ-2-CN, Chinese version of short-form McGill Pain Questionnaire-2.
