Table 3. Fit indices for CFA models of the SPANE (best fitting model in bold).
Models | χ2 | Df | CFI | SRMR | AIC | RMSEA |
1a. Single factor | 64632.7 | 54 | .645 | .1545 | 64680.70 | .237 |
1b. Single factor, correlated errors (CE) permitted | 19636.5 | 42 | .892 | .1318 | 19708.53 | .148 |
2a. Positive experience (PE) and negative experience (NE) as correlated factors | 15823.4 | 53 | .913 | .0503 | 15873.43 | .118 |
2b. PE and NE as correlated factors, CE permitted | 4611.2 | 41 | .975 | .0283 | 4685.23 | .072 |
3. Bifactor model, PE and NE as correlated factors | 6707.3 | 41 | .963 | .0309 | 6781.29 | .087 |
Note. Values >.90 for the CFI indicate a reasonable fit, whereas those >.95 suggests a good fit. Values <.05 for the RMSEA indicate a good fit, and values between .05 and .08 for the RMSEA indicate a reasonable fit. Values ≤.08 for the SRMR indicate a good fit; for AIC, the smaller the better.
