Principal Component Analysis is a translation of the data so the new origin is the mean and then a rotation so that the first axis is in the direction which explains the largest amount of variance, the second axis is the axis orthogonal to the first that explains the largest amount of the remaining variance, the third is the axis orthogonal to the first two that explains the largest amount of what remains and so on.

The analysis highlighted 6 factors (the first six eigenvalues were 11.4, 4.2, 2.4, 2.2, 1.7, 1.6) accounting for 41.2 % of the total variance.

In hierarchical regression analyses with the various ENRICH factor scores as dependent variables and job satisfaction as the independent variable in the first block, the two SSQ factors in the second block, and the WOC factors in the third block, between 24 and 38 % of the variance in seven of the nine ENRICH factors (not significant model for «Family & Friends» and «Marriage & Children») could be explained by the variation in all the independent variables with varying weight of the several independent variables (Table 3).
