Dimensional assessment using exploratory factor analysis.
| Panel (a) Fit and factor dominance results | ||||||
|---|---|---|---|---|---|---|
| Model | SRMRS | RMSEA | CFI | EVC | PA | BIC |
| 1 factor | .086 | .073 | .981 | .850 | 1 factor (62.37%) | 1002.05 |
| 3 factors | .034 | .032 | .997 | – | – | 679.18 |
| Panel (b) Added-value and quality of the solutions results | ||||
|---|---|---|---|---|
| Added-value | H-index/marginal reliability(EAP scores) | Alpha reliability (raw scores) | Ordinal alpha | |
| General factor | -- | .955 | .90 | .93 |
| Depression factor | .925 (.487) | .919 | ||
| Anxiety factor | .952 (.572) | .952 | ||
| Somatization factor | .847 (.278) | .850 | ||
Note: SMRS = Standardized Root Mean Squared Residual; RMSEA = Root Mean Square Error of Approximation; CFI = Comparative Fit Index; ECV = Explained common variance; PA: Parallel Analysis; BIC: Bayesian Information Criterion; Added-Value results = first value: mean squared error reduction when predicting from the corresponding factor, second value within brackets: mean squared error reduction when predicting from the general factor.
