Summary comparison of varimax and oblimin solutions
Criterion	Varimax	Oblimin	Interpretation
Number of factors	4	4	Identical structure
Factor composition	Stable	Stable	No item shifts
Factor loadings	> 0.70	> 0.70	Strong in both
Cross-loadings	None	None (<0.30)	Clean structure
Factor correlations	Not estimated	0.36–0.45	Moderately correlated
Overall conclusion	Clear structure	Consistent structure	Robust solution
