Table 1.
Fit indices of the confirmatory factor analysis (original 2-factor model) and exploratory factor analysis based on the RPQ
| Factor structure | TLI | CFI | RMSEA | Estimated RMSEA | Eigen-value |
|---|---|---|---|---|---|
| CFA | 0.954 | 0.958 | 0.056–0.066 | 0.061 | - |
| EFA | |||||
| 2-factors | 0.958 | 0.965 | 0.053–0.063 | 0.058 | 1.46 |
| 3-factors | 0.974 | 0.981 | 0.040–0.052 | 0.046 | 1.33 |
| 4-factors | 0.988 | 0.982 | 0.032–0.045 | 0.038 | 0.891 |
The three factor model shows the best fit, since the Eigen-value is >1, the RMSEA <0.06 and the TLI and CFI are >0.90. Furthermore, the two factor model did not correspond with the original two factor model as used in the CFA
