Table 2.

Principle component analysis with varimax rotation (Kaiser-normalization); criterion for N° of factors extracted: Eigenvalue >1 (Kaiser-Guttman-Criterion); values x with −0.100 < x < 0.100 are not shown; factor loadings above 0.500 are considered high loading and highlighted in bold gray shadow.
