The dimensionality analyses performed revealed factorial structures theoretically interpretable, using two alternative forms of item analysis. In the final version, EPE is composed of 25 items within a four factor solution (35.5% of total variance explained), named as follows: (1) epistemological sophistication; (2) epistemological naivety; (3) unchanging knowledge; and (4) learning quickl
