EFA Output Summary
Extraction Method: Principal Component Analysis (PCA)
Rotation Method: Varimax rotation (orthogonal)
KMO and Bartlett’s Test
- KMO Measure: 0.81 → indicates good sampling adequacy
- Bartlett’s Test of Sphericity: χ²(45) = 210.35, p < .001 → significant
These results suggest that the data are suitable for factor analysis.
Factors and Items Retained
- Total items: 10
- Number of factors retained: 2 factors
The decision was based on:
- Eigenvalues > 1 (Kaiser’s criterion)
- Scree plot showing a clear break after the second factor
- Factor loadings above 0.50
Two items were removed because they had low loadings (< .40) or cross-loadings on multiple factors.
