Mexico /study 1 EFA: validity, data resulting from the factor
analysis suggest that four dimensions (Competence/
productivity, Satisfaction, Empowerment/independence
and Social belonging) represented the best fit. Correlations among factors converge
with theoretical assumptions, which postulate
that the factors are interrelated. Low-medium relations
between sub-scales (from 0.32 to .60,P<0.1), and moderate correlations with total were
found (from 0.65 to 0.81). Study 2 / Spain Correlations among factors
converged with theoretical assumptions, given the
low inter-factor correlations (from 0.13 to 0.36) and
the medium–moderate factor-total correlations (from
0.53 to 0.77; P < 0. 01).- Study design
